Auto It crashed with Error $IEComErrorNumberHex = 00000000

7 posts in this topic

Good afternoon !

Please, help me with my code: i have strange error while run this code:

In this code i create main window with embedding IE window frame.

In IE frame i injected HTML code with one button and set event on this button.

If you press button, event fired and run 'Event_IE_BTN_onclick' that create new window with embedding new IE.

While i injecting any code or run _IELoadWait, AutoIt Crashed with strange errors.

Please, help!

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#include <IE.au3>


Opt("GUIOnEventMode", 1)
Opt("GUICloseOnESC",1)


Global $MainWindow  = GUICreate("Main Window", 233, 122, 335, 214)
GUISetOnEvent($GUI_EVENT_CLOSE, "CLOSEMain", $MainWindow)


$ieFrame = _IECreateEmbedded ()
 GUICtrlCreateObj($ieFrame, 10, 10, 200, 100)
 $ieFrame.navigate("about:blank")
 _IELoadWait($ieFrame)

 _IEDocWriteHTML($ieFrame, "<html><body><button name='BTN'>Press This</button></body></html>")
 _IELoadWait($ieFrame)

  ObjEvent(_IEGetObjById($ieFrame, "BTN"), "Event_IE_BTN_")

 _IEErrorHandlerRegister("MyErrFunc")


GUISetState(@SW_SHOW, $MainWindow) ; will display an empty dialog box

You're getting an error but it doesn't crash.

Some improvements made:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

#include <IE.au3>


Opt("GUIOnEventMode", 1)
Opt("GUICloseOnESC",1)


Global $MainWindow  = GUICreate("Main Window", 233, 122, 335, 214)
GUISetOnEvent($GUI_EVENT_CLOSE, "CLOSEMain", $MainWindow)


$ieFrame = _IECreateEmbedded ()
 GUICtrlCreateObj($ieFrame, 10, 10, 200, 100)
 _IENavigate($ieFrame, "about:blank")

 _IEDocWriteHTML($ieFrame, "<html><body><button id=""BTN"">Press This</button></body></html>")
 _IELoadWait($ieFrame)

$obj = _IEGetObjById($ieFrame, "BTN")
ObjEvent($obj, "Event_IE_BTN_")

 _IEErrorHandlerRegister("MyErrFunc")


GUISetState(@SW_SHOW, $MainWindow) ; will display an empty dialog box

While 1
  Sleep(1000)  ; Idle around
WEnd

Exit

;-- Open new window when button in 'IE' pressed
Func Event_IE_BTN_onclick()
    
    Global $ParentWindow  = GUICreate("Parent Window", 233, 122, 335, 214)
    $ieParentFrame = _IECreateEmbedded ()
    GUICtrlCreateObj($ieParentFrame, 10, 10, 200, 100)
    _IENavigate($ieParentFrame, "about:blank")

    _IEDocWriteHTML($ieParentFrame, "<html><body>Simple Text</body></html>")
    _IELoadWait($ieParentFrame)

    GUISetState()

EndFunc

;-- Close main window
Func CLOSEMain()
    Exit
EndFunc

;-- My Error Handler
Func MyErrFunc()
    SetError(0,0,0)
    Return
EndFunc  ;==>MyErrFunc

Yes, i getting error.

But if you modify code for closing popup window and click five or six times on button (and close pop up window, of course), Auto It crashed.

For my application this is really big problem ;-(

What error do you get using the standard _IEErrorHandlerRegister() instead of your custom handler?

If i use _IEErrorHandlerRegister(), and seen this error message

--> COM Error Encountered in IEErrSample.au3

----> $IEComErrorScriptline =

----> $IEComErrorNumberHex = 00000000

----> $IEComErrorNumber =

----> $IEComErrorWinDescription =

----> $IEComErrorDescription =

----> $IEComErrorSource =

----> $IEComErrorHelpFile =

----> $IEComErrorHelpContext =

----> $IEComErrorLastDllError =

When i not use any error handler (i think, in this cause uses internal handler)

C:\Program Files\AutoIt3\Include\IE.au3 (4341) : ==> Variable must be of type "Object".:

$IEComErrorScriptline = $oIEErrorHandler.scriptline

$IEComErrorScriptline = $oIEErrorHandler^ ERROR

->07:58:29 AutoIT3.exe ended.rc:1

I think, this strange behaviour of IE component is caused by incorrect handling of events: error

error occurs only when creating a new window with IE in the processing of event (onclick in my sample)

P.S. I ran the code in this style on different computers (WinXP, IE7/IE8) and all the time the result was the same: there was an error and after a few opened windows AutoIT crashed

Must be something strange you are doing. I have just tried this on second computer and it was fine.

First test was on Win7 with IE8 and second test was on Win Vista with IE8. I have an old Win XP machine with IE6 I can test it on, but I'll need to dust it off..
