Popular Post LarsJ Posted February 16, 2021 Popular Post Share Posted February 16, 2021 (edited) The ObjectFromTag() function is used to implement COM callback interfaces, pointers and objects. This is documentation for using the function. When talking about ObjectFromTag(), you cannot get around ObjCreateInterface(). ObjCreateInterface() was introduced in AutoIt version 3.3.8.0 (2011-12-23). The function is coded in the C/C++ language by trancexx. At the top of the official documentation there is a large warning box. A few comments on this warning: "This feature is experimental". No it's not. A function that has been used for more than 9 years to implement advanced code like the following is no longer experimental but has long proven its worth: IUIAutomation MS framework automate chrome, FF, IE, .... created by junkew August 2013 Newer versions of UIA code in this and other threads Using .NET library with AutoIt, possible? and several derived and advanced examples Implementing IRunningObjectTable Interface File/Windows Explorer examples Microsoft Edge - WebView2 As well as a myriad of other examples "It may not work, may contain bugs". The function works and it contains no bugs. This has long been proven by the examples above. "may be changed or removed without notice". On what grounds? The function works, contains no bugs, and adds lots of value to the AutoIt language. "DO NOT REPORT BUGS OR REQUEST NEW FEATURES FOR THIS FEATURE". There's really no reason for that. ObjectFromTag() is implemented as pure AutoIt code and is also made by trancexx. One of the first versions of the function is available in the Ribbon example. One of the latest versions of the function coded by trancexx is found in this post. Description tagsBoth ObjCreateInterface() and ObjectFromTag() use description tags to create objects with methods and properties. A description tag is a string that looks like this (the example of ObjCreateInterface()) $dTag_ITaskbarList = _ "HrInit hresult();" & _ "AddTab hresult(hwnd);" & _ "DeleteTab hresult(hwnd);" & _ "ActivateTab hresult(hwnd);" & _ "SetActiveAlt hresult(hwnd);" Here, the description tag is split into substrings for each method/property. ITaskbarList is the name of the COM interface. The name to the left of each substring is the name of the method/property. hresult in the middle is the method/property return type (always hresult for COM methods/properties), and the data types to the right in parentheses are parameter data types. If there are several parameters, the data types must be separated by a semi colon. Methods/properties of the description tag string must be in correct Vtable order. Vtable order In the Microsoft documentation for the ITaskbarList interface, methods/properties are listed in alphabetical order. But it's not possible to determine the correct Vtable order from this alphabetical list. The only way to determine the correct Vtable order is to study the interface in the appropriate C/C++ header file (shobjidl_core.h for ITaskbarList). All Microsoft header files are included in the Windows SDK. To access the header files, it's necessary to install the Windows SDK on your PC. The header files are located in the folder "E:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0" or similar. When you need a specific header file, it's easiest to search for it. shobjidl_core.h is found in the um subfolder. This is the definition of ITaskbarList in shobjidl_core.h: expandcollapse popup/* interface ITaskbarList */ /* [object][uuid] */ EXTERN_C const IID IID_ITaskbarList; #if defined(__cplusplus) && !defined(CINTERFACE) MIDL_INTERFACE("56FDF342-FD6D-11d0-958A-006097C9A090") ITaskbarList : public IUnknown { public: virtual HRESULT STDMETHODCALLTYPE HrInit( void) = 0; virtual HRESULT STDMETHODCALLTYPE AddTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE DeleteTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE ActivateTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE SetActiveAlt( /* [in] */ __RPC__in HWND hwnd) = 0; }; #else /* C style interface */ typedef struct ITaskbarListVtbl { BEGIN_INTERFACE HRESULT ( STDMETHODCALLTYPE *QueryInterface )( __RPC__in ITaskbarList * This, /* [in] */ __RPC__in REFIID riid, /* [annotation][iid_is][out] */ _COM_Outptr_ void **ppvObject); ULONG ( STDMETHODCALLTYPE *AddRef )( __RPC__in ITaskbarList * This); ULONG ( STDMETHODCALLTYPE *Release )( __RPC__in ITaskbarList * This); HRESULT ( STDMETHODCALLTYPE *HrInit )( __RPC__in ITaskbarList * This); HRESULT ( STDMETHODCALLTYPE *AddTab )( __RPC__in ITaskbarList * This, /* [in] */ __RPC__in HWND hwnd); HRESULT ( STDMETHODCALLTYPE *DeleteTab )( __RPC__in ITaskbarList * This, /* [in] */ __RPC__in HWND hwnd); HRESULT ( STDMETHODCALLTYPE *ActivateTab )( __RPC__in ITaskbarList * This, /* [in] */ __RPC__in HWND hwnd); HRESULT ( STDMETHODCALLTYPE *SetActiveAlt )( __RPC__in ITaskbarList * This, /* [in] */ __RPC__in HWND hwnd); END_INTERFACE } ITaskbarListVtbl; interface ITaskbarList { CONST_VTBL struct ITaskbarListVtbl *lpVtbl; }; The upper part of the definition is used in the C++ language. The lower part is used in the C language. When translating the definition to AutoIt, it's easiest to look at the C++ definition: /* interface ITaskbarList */ /* [object][uuid] */ EXTERN_C const IID IID_ITaskbarList; #if defined(__cplusplus) && !defined(CINTERFACE) MIDL_INTERFACE("56FDF342-FD6D-11d0-958A-006097C9A090") ITaskbarList : public IUnknown { public: virtual HRESULT STDMETHODCALLTYPE HrInit( void) = 0; virtual HRESULT STDMETHODCALLTYPE AddTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE DeleteTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE ActivateTab( /* [in] */ __RPC__in HWND hwnd) = 0; virtual HRESULT STDMETHODCALLTYPE SetActiveAlt( /* [in] */ __RPC__in HWND hwnd) = 0; }; Note that the order of the methods in the description tag string above corresponds to the order of the methods in the C++ definition. Names of methods/properties and the correct Vtable order can be copied directly from the C++ definition. Parameter data types The parameter data types that can be used in the description tag string are listed in the ObjCreateInterface() documentation. Both the header file and the Microsoft documentation can be used to help you find the right data types. In many cases, the data type in the header file or Microsoft documentation corresponds directly to one of the data types in the ObjCreateInterface() documentation. In other cases, it's necessary to translate the data type to one of the valid AutoIt data types. Filling in the parameter data types is the most time consuming task of creating the description tag string. Fortunately, it's enough to fill in the data types for the methods/properties you actually need. For methods/properties you don't need, you can simply enter an empty parenthesis, as is the case in the "HrInit hresult();" substring (in this case because HrInit doesn't actually take any parameters). You can omit the parameter data types for methods/properties that are not to be used in the first place, but all methods/properties must be specified in the correct Vtable order. IUnknown interface All COM interfaces inherits from the IUnknown interface. It's indicated in the C++ definition by this line ITaskbarList : public IUnknown Because all COM interfaces inherits from the IUnknown interface, don't specify IUnknown methods/properties in the description tag string. IUnknown methods/properties are added automatically in both ObjCreateInterface() and ObjectFromTag() functions. $sIID and $sCLSID Note that this line in the AutoIt code $sIID_ITaskbarList = "{56FDF342-FD6D-11D0-958A-006097C9A090}" corresponds to this line in the C++ definition MIDL_INTERFACE("56FDF342-FD6D-11D0-958A-006097C9A090") And that this line in the AutoIt code $sCLSID_TaskbarList = "{56FDF344-FD6D-11D0-958A-006097C9A090}" corresponds to these lines in the C++ definition (further down in the header file) class DECLSPEC_UUID("56FDF344-FD6D-11D0-958A-006097C9A090") TaskbarList; ObjectFromTag() functionThe version of ObjectFromTag() that I'm using is based on this version by trancexx. My first version is contained in the 7z-file below and coded in ObjectFromTag-a.au3 dated 2014-01-14. My current version is coded in ObjectFromTag.au3 dated 2021-02-06. The function is defined as follows: Func ObjectFromTag( _ $sFunctionPrefix, _ ; Presents methods/properties with the same prefix name $tagInterface, _ ; Interface description tag string ByRef $tInterface, _ ; Interface struct (DllStruct) $bObject = True, _ ; Return object or object pointer $bPrint = False, _ ; Print information in SciTE console $bIsUnknown = True, _ ; Inherits from the IUnknown interface $sIID = "{00000000-0000-0000-C000-000000000046}" ) ; $sIID_IUnknown ObjectFromTag() exampleAs an example of using the function, I'll show how to create the first part of the WebView2-1.au3 example here (WebView2-1-0.au3, all required code and files are contained in the 7z-file below). According to the Getting started with WebView2 example, the prerequisites for running the code are installing the Microsoft Edge Chromium version and the WebView2 Runtime (Evergreen Bootstrapper). expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui ; Project includes #include "..\Includes\WV2Interfaces.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate( True ) ; DllCall CreateCoreWebView2EnvironmentWithOptions Local $hWebView2Loader = DllOpen( @AutoItX64 ?

However, since it's only about half of all the code, an empty window without web content is displayed. A crucial point, of course, is to create this code from scratch. I've read the WebView2 documentation and especially the API reference documentation and studied the HelloWebView.cpp and WebView2.ahk examples (contained in the 7z-file). By running the examples and adding "ConsoleWrites" to the code, I've found that the examples can be translated to AutoIt code as shown. Because the WebView2 code is new code that's still under development, the WebView2.h header file isn't included in the Windows SDK. WebView2.h can instead be downloaded in a NuGet package as described in the WebView2 documentation. I'll focus on this part of the code: ; Create callback interfaces and functions CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate( True ) The code creates the CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler callback interface and its functions. CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate() in WV2Interfaces.au3: Func CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate( $bPrint = False ) $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ ObjectFromTag( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_", _ $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, False, $bPrint ) If $bPrint Then ConsoleWrite( "$pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = " & _ $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler & @CRLF & @CRLF ) EndFunc The function executes ObjectFromTag(), which creates the callback interface and its functions. Note the False parameter just before $bPrint. False means that ObjectFromTag() returns an object pointer instead of the object itself. It seems that all WebView2 callback interfaces are created from an object pointer and not the object itself. Implement these steps to create the callback interface and its functions: Step 1: Create the description tag for ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler callback interface Step 2: Execute ObjectFromTag() with the $bPrint = True parameter Step 3: Copy the functions printed in the SciTE console into the code and run the code again Step 4: Continue executing ObjectFromTag() and copy the functions until there are no more errors Step 5: Test the code to check if the interface functions are called as expected Step 1The $dtag for the ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler callback interface can be created based on the information in WebView2.h (search the interface) and the Microsoft documentation (google the interface): Global Const $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ "Invoke hresult(hresult;ptr*);" Step 2Execute ObjectFromTag() with the $bPrint = True parameter this way (WebView2-1-1.au3) expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui Global $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler Global Const $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ "Invoke hresult(hresult;ptr*);" ; Project includes ;#include "..\Includes\WV2Interfaces.au3" #include "..\Includes\ObjectFromTag.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ ObjectFromTag( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_", _ $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, False, True ) ; $bPrint = True ; Show WebView2 GUI GUISetState( @SW_SHOW ) ; Loop While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd ; Cleanup EndFunc SciTE console output: Func CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_QueryInterface( $pSelf, $pRIID, $pObj ) ; Ret: long Par: ptr;ptr* ConsoleWrite( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_QueryInterface()" & @CRLF & @CRLF ) Return 0 ; S_OK = 0x00000000 #forceref $pSelf, $pRIID, $pObj EndFunc @error = 3 Func CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_AddRef( $pSelf ) ; Ret: dword ConsoleWrite( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_AddRef()" & @CRLF & @CRLF ) Return 1 ; For AddRef/Release #forceref $pSelf EndFunc @error = 3 Func CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Release( $pSelf ) ; Ret: dword ConsoleWrite( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Release()" & @CRLF & @CRLF ) Return 1 ; For AddRef/Release #forceref $pSelf EndFunc @error = 3 Func CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Invoke( $pSelf, $long, $ptr ) ; Ret: long Par: long;ptr* ConsoleWrite( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Invoke()" & @CRLF & @CRLF ) Return 0 ; S_OK = 0x00000000 #forceref $pSelf, $long, $ptr EndFunc @error = 3 @error = 3 is an error code from DllCallbackRegister() in the ObjectFromTag() function and apparently means that the functions don't exist.

If you get a CreateCoreWebView2EnvironmentWithOptions ERR from the DllCall() function and you're sure that the function is coded correctly, read this post by Chimp for a description and solution to the problem. Note that for all WebView2 callback interfaces, it seems that the Invoke() method is interesting, while the other methods/properties aren't so interesting. To proceed with the WebView2-1.au3 example (included as WebView2-1-a.au3) add code in the CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Invoke() function. 7z-fileThe 7z-file contains source code for the UDF and examples and other files needed to run the code.

LarsJ Posted February 19, 2021 Author Share Posted February 19, 2021 (edited) Responding eventsIn the first post, the ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler callback interface was implemented. According to the Microsoft documentation, this callback interface is implemented to be able get an object pointer to the the ICoreWebView2Environment through a DllCall() to either the CreateCoreWebView2Environment() or CreateCoreWebView2EnvironmentWithOptions() functions implemented in WebView2Loader.dll. ICoreWebView2Environment represents the WebView2 environment on the PC. You pass the $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler pointer to one of the dll-functions. As a consequence of the function call, the dll-function generates a CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler event. You respond to this event by adding code in the callback function CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_Invoke() (WebView2-1-4.au3) expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui Global $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler Global Const $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ "Invoke hresult(hresult;ptr*);" ; ICoreWebView2Environment interface Global $oCoreWebView2Environment Global Const $sIID_ICoreWebView2Environment = "{B96D755E-0319-4E92-A296-23436F46A1FC}" Global Const $dtag_ICoreWebView2Environment = _ "CreateCoreWebView2Controller hresult(hwnd;ptr);" & _ "CreateWebResourceResponse hresult();" & _ "get_BrowserVersionString hresult();" & _ "add_NewBrowserVersionAvailable hresult();" & _ "remove_NewBrowserVersionAvailable hresult();" ; Project includes ;#include "..\Includes\WV2Interfaces.au3" #include "..\Includes\ObjectFromTag.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ ObjectFromTag( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_", _ $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, False, True ) ; $bPrint = True ; DllCall CreateCoreWebView2EnvironmentWithOptions Local $hWebView2Loader = DllOpen( @AutoItX64 ?

From this pointer the CoreWebView2Environment object can be created: ; Create CoreWebView2Environment object $oCoreWebView2Environment = ObjCreateInterface( $ptr, $sIID_ICoreWebView2Environment, $dtag_ICoreWebView2Environment ) ConsoleWrite( "IsObj( $oCoreWebView2Environment ) = " & IsObj( $oCoreWebView2Environment ) & @CRLF & @CRLF ) ; Set $pCoreWebView2CreateCoreWebView2ControllerCompletedHandler callback pointer for the WebView2 GUI ;$oCoreWebView2Environment.CreateCoreWebView2Controller( $hGui, $pCoreWebView2CreateCoreWebView2ControllerCompletedHandler ) ; Forces CoreWebView2CreateCoreWebView2ControllerCompletedHandler_Invoke() below to be executed Data for the ICoreWebView2Environment interface is included at the top of WebView2-1-4.au3. The most interesting method of the CoreWebView2Environment object is CreateCoreWebView2Controller(). The method takes our AutoIt GUI and a pointer to an ICoreWebView2CreateCoreWebView2ControllerCompletedHandler callback interface as input parameters and creates a WebView2 window embedded in the AutoIt GUI. Create callback interfaceBefore we can execute the CreateCoreWebView2Controller() method, we need to create the ICoreWebView2CreateCoreWebView2ControllerCompletedHandler callback interface and its functions so that we can pass the object pointer to the method. We create the callback interface and its functions by performing the 5 steps described in first post. Step 1The $dtag for the ICoreWebView2CreateCoreWebView2ControllerCompletedHandler callback interface can be created based on the information in WebView2.h (search the interface) and the Microsoft documentation (google the interface): Global Const $dtag_ICoreWebView2CreateCoreWebView2ControllerCompletedHandler = _ "Invoke hresult(hresult;ptr*);" Continue with steps 2 - 4 as described in first post. Step 5To test whether the interface functions are called as expected, we need to execute the CreateCoreWebView2Controller() method in the code above. The CoreWebView2CreateCoreWebView2ControllerCompletedHandler_Invoke() function is called as a consequence of executing this method. Check if the interface functions are called as expected (WebView2-1-5.au3) expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui Global $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler Global Const $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ "Invoke hresult(hresult;ptr*);" Global $pCoreWebView2CreateCoreWebView2ControllerCompletedHandler, _ $tCoreWebView2CreateCoreWebView2ControllerCompletedHandler Global Const $dtag_ICoreWebView2CreateCoreWebView2ControllerCompletedHandler = _ "Invoke hresult(hresult;ptr*);" ; ICoreWebView2Environment interface Global $oCoreWebView2Environment Global Const $sIID_ICoreWebView2Environment = "{B96D755E-0319-4E92-A296-23436F46A1FC}" Global Const $dtag_ICoreWebView2Environment = _ "CreateCoreWebView2Controller hresult(hwnd;ptr);" & _ "CreateWebResourceResponse hresult();" & _ "get_BrowserVersionString hresult();" & _ "add_NewBrowserVersionAvailable hresult();" & _ "remove_NewBrowserVersionAvailable hresult();" ; Project includes ;#include "..\Includes\WV2Interfaces.au3" #include "..\Includes\ObjectFromTag.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions $pCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler = _ ObjectFromTag( "CoreWebView2CreateCoreWebView2EnvironmentCompletedHandler_", _ $dtag_ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, _ $tCoreWebView2CreateCoreWebView2EnvironmentCompletedHandler, False, True ) ; $bPrint = True $pCoreWebView2CreateCoreWebView2ControllerCompletedHandler = _ ObjectFromTag( "CoreWebView2CreateCoreWebView2ControllerCompletedHandler_", _ $dtag_ICoreWebView2CreateCoreWebView2ControllerCompletedHandler, _ $tCoreWebView2CreateCoreWebView2ControllerCompletedHandler, False, True ) ; $bPrint = True ; DllCall CreateCoreWebView2EnvironmentWithOptions Local $hWebView2Loader = DllOpen( @AutoItX64 ?

LarsJ Posted February 20, 2021 Author Share Posted February 20, 2021 UDF versionThe definitions at top of WebView2-1-6.au3 are starting to fill up a lot. It's time to support the examples with a UDF: WV2Interfaces.au3. WV2Interfaces.au3 contains all the interface definitions as well as the callback functions generated by ObjectFromTag(). These callback functions always seem to consist of 4 functions: $sFunctionPrefix_QueryInterface() $sFunctionPrefix_AddRef() $sFunctionPrefix_Release() $sFunctionPrefix_Invoke() For the first 3 functions, the code appears to be constant. These functions can be moved directly into the UDF. For the last function, Invoke(), the code varies depending on the functionality we want in the WebView window. Therefore, Invoke() is placed in the UDF as a function skeleton commented out. When we need to use the Invoke() function in our own code, we can start by copying the function skeleton, and add code as needed. WebView2-1-7.au3 is similar to WebView2-1-a.au3 (WebView2-1-a.au3 is a copy of the WebView2-1.au3 example here) but is slightly updated: expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui ; Project includes #include "..\Includes\WV2Interfaces.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate( True ) CoreWebView2CreateCoreWebView2ControllerCompletedHandlerCreate( True ) ; DllCall CreateCoreWebView2EnvironmentWithOptions Local $hWebView2Loader = DllOpen( @AutoItX64 ?

The Invoke() method returns an ICoreWebView2Controller interface. The creation of the ICoreWebView2Environment and ICoreWebView2Controller interfaces required to create a WebView window appears to be implemented as a kind of pseudo-events to handle code running asynchronously. Creating a WebView window is about creating two callback interfaces and executing code in a DllCall function and a method function to call the corresponding Invoke() methods. Real events in a WebView windowAn example of real events (due to user actions that may occur multiple times) in a WebView window is NavigationStarting events as coded in WebView2-2-0.au3 (similar to WebView2-2-a.au3 but slightly updated (WebView2-2-a.au3 is a copy of the WebView2-2.au3 example here)) expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w- 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7 #AutoIt3Wrapper_UseX64=y Opt( "MustDeclareVars", 1 ) #include <MsgBoxConstants.au3> #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPICom.au3> #include <WinAPI.au3> Global $hGui ; Project includes #include "..\Includes\WV2Interfaces.au3" WebView2() Func WebView2() ; Create WebView2 GUI $hGui = GUICreate( "WebView2 Sample", 1200, 900, -1, -1, $WS_OVERLAPPEDWINDOW ) ; Initialize COM _WinAPI_CoInitialize( $COINIT_APARTMENTTHREADED ) ; Create callback interfaces and functions CoreWebView2CreateCoreWebView2EnvironmentCompletedHandlerCreate( True ) ; Create WebView window CoreWebView2CreateCoreWebView2ControllerCompletedHandlerCreate( True ) ; Create WebView window CoreWebView2NavigationStartingEventHandlerCreate( True ) ; Create event handler ; DllCall CreateCoreWebView2EnvironmentWithOptions Local $hWebView2Loader = DllOpen( @AutoItX64 ?

LarsJ Posted February 22, 2021 Author Share Posted February 22, 2021 $oObject.AddRef()In WebView2-2-0.au3 in the post above, a $oCoreWebView2NavigationStartingEventArgs.AddRef() code line is added after the object is created. This code line is required to prevent 0xC0000005 errors (STATUS_ACCESS_VIOLATION). It can be a little difficult to figure out when this line of code is needed. The easiest way is usually to run the code and see if the 0xC0000005 error occurs. In that case, try adding the code line and see if the error disappears. Global variablesThe Invoke() functions are defined and created based on description tags for callback interfaces and they are executed due to events. Therefore, the easiest way to pass data between these functions and the rest of the code is to use global variables. If there are many Invoke() functions, it can result in a fairly large number of global variables. There's not much to do about it. At least not in the program development phase. Once the program is complete, you may be able to group the variables into a single or a few global arrays. WebView2 projectThe WebView2 project has been used as a starting point for the examples above. If you are interested in a complete translation of the WebView2 API into AutoIt, keep an eye on the original project.

davidkim Posted April 2, 2021 Share Posted April 2, 2021 (edited) Thank your for sharing this excellent UDF. I'm sure many AutoIt-Users are looking at your work with a great expectaion. I have run your examples and they all run as expected. Here I have a couple of questions. My first question is: how do I get the event id when I interface with Edge, clicking a button for example? ex html: <div id="exit">exit</exit> <div id="button_action">action</exit> id:exit or id:button_action click event receved function not search... ----------------------- ie using objevent . Local $oEventsDoc = ObjEvent($oIE.document, "ie_", "HTMLDocumentEvents2") Volatile Func ie_onclick($oEvtObj) If IsObj($oEvtObj) Then Local $sId = $oEvtObj.srcElement.id & "" ConsoleWrite($sId & @CRLF) Switch $sId Case "exit" Exit Case "start_action" ;start_action func EndSwitch EndIf EndFunc ------------------------- Second, how can I inject a jQuery in webview2. In IE, for example, I could use $jQuery = $oIE.document.parentWindow.jQuery. Can I do this in webview2 as well?

LarsJ Posted April 2, 2021 Author Share Posted April 2, 2021 All AutoIt code that exists in relation to Microsoft Edge (Chromium) and WebView2 can be found in the original thread. And the existing code is so far largely limited to a translation of the Getting started with WebView2 examples into AutoIt. You can download the AutoIt translation of the examples in bottom of this post. My examples here are all based on code in the original thread. So if you're interested in WebView2 code, study the original thread. But as already mentioned, not much code has been implemented so far. Sufficient code has simply not been implemented to make it practically usable in real-world examples. Much more of the code in WebView2.h (included in the code for the AutoIt examples) needs to be translated into AutoIt before the code is practically applicable in real examples. davidkim 1 Controls, File Explorer, ROT objects, UI Automation, Windows Message MonitorCompiled code: Accessing AutoIt variables, DotNet.au3 UDF, Using C# and VB codeShell menus: The Context menu, The Favorites menu.

Gianni Posted April 6, 2021 Share Posted April 6, 2021 Hi @davidkim, it doesn't work that way. You have to: 1) place your script somewhere on the managed webpage. In this case we just inject the script into the blank page (see lines 115 and 131-138) 2) call that function from AutoIt using the ExecuteScript method (see lines 60-63) 3) and get the returned result from within the callback function CoreWebView2ExecuteScriptCompletedHandler_Invoke() where it is passed in the third parameter $wstr (see line 126) Here the larsj script referred to in my previous link slightly modified in a very basic way just to express proof of concept. Put the numbers in the first 2 input boxes, click on the ExecuteScript button and see the result returned by the script in the box on the right p.s.
