  1. Since W8.1 (actually IE 11 with W7 will work also) microsoft has a Javascript runtime that can be called from scripting languages As shown in this example from C++: https://iobservable.net/blog/2013/11/12/introduction-to-jsrt/ By loading either JSCRIPT9.DLL or CHAKRA.DLL you can embed ECMA JavaScript in your application And implemented here in AutoHotKey https://autohotkey.com/boards/viewtopic.php?f=6&t=5739 Triggered by other threads: https://www.autoitscript.com/forum/topic/185883-accessing-autoit-variables/ https://iobservable.net/blog/2013/11/12/introduction-to-jsrt/ https://www.autoitscript.com/forum/topic/184824-chakracore-udf-executing-javascript-in-autoit/ http://eclipsesource.com/blogs/2016/04/06/getting-started-with-microsoft-chakracore/ This code is almost working but unfortunately not with the expected output.

  2. Function Reference _GUIRegisterMsgEx.au3 Register a user defined function for a known Windows Message ID (WM_MSG) to an individual ctrl using Call Back! Sintax: _GUICtrlMsg_Register( controlID, MsgID, "Function" ) _GUICtrlMsg_UnRegister( hWnd [, MsgID ]) Supports: ; AutoIt GUI controls to register message! Downloads: Version: 0.9b _GUIRegisterMsgEx_(RedirectLink).html Note: The functions have new parameters!, see fixes below! You can use this UDF in controls that consume internally specific Windows Message ID that we could not register with the GUIRegisterMsg function, eg: WM_CHAR, WM_KEYDOWN, WM_KEYUP are consumed by an edit control. Usage example is included! Sample: Fixes: I.e: Func _MyRegisterFunc( $hCtrlID, $iMsgID, $WParam, $LParam ) ;... EndFunc The 4 parameters have the following values: hCtrlID, The control handle in which the message is registered.iMsg, The Windows message ID.wParam, The first message parameter as hex value.lParam, The second message parameter as hex value. (Position. Parameter, Meaning) 0.9.0812.2600b09/09/2012 -> First release!I like to use UDFs, although I think this will not be very useful, I hope someone will find useful! Regards, João Carlos.
  3. Hello, I would like to develop a DLL for autoit but I have some questions. I use Autoit 3.3.9.0beta and codeblock with mingw for the DLL part. I have the DLL, a external program developped in C to test this DLL and an autoit program to test this DLL. The DLL have only one function: addition to add two integer and return the result. This is part of my source code (I put the full project in attachment): int DLL_EXPORT addition(int integer1, int integer2) { return integer1 + integer2; } #define DLL_EXPORT __declspec(dllexport) #ifdef __cplusplus extern "C" { #endif int DLL_EXPORT addition(int integer1, int integer2); #ifdef __cplusplus } #endif local $hDll = DllOpen("LibTest.dll") $result = DllCall($hDll, "int:cdecl","addition", "int",3, "int",7) MsgBox(4096, "In AutoIt", "3 + 7 = " & $result & @CRLF & "error = " & @error) DllClose($hDll) ExitThe returned value on my DLL function is correct (=10) with my C test program but not in autoit (=0). The parameters is correctly passed to the DLL in both case (I display it in the DLL with a msgbox). I have tested with __stdcall and without. What is wrong with my code?When I use the __stdcall version, my DLL function name change to addition@8, why this? and how to avoid this? (sorry I not realy familiar with DLL development).I would like to call an autoit function in my DLL. I suppose I need to use the DllCallbackRegister to get a pointer on my autoit function and to pass it to a function in my DLL, like what it’s done in the Example of DllCallbackRegister with EnumWindows. But in my DLL how I call this pointer? Does I need a specific mechanism or I can call it like another C function pointer? And how to pass parameters to the autoit callback function and eventualy get a return value?Thank you for your help.dll.zip
