ControlSend script blocking bug?

I just tested the workaround 1 that was posted above. I commented out the first line and added a declaration for the dummy. Works!!

;~ $gGUIDummy = GUICreate("")
Local $gGUIDummy
Run("notepad.exe")
$HWND = WinWait("Untitled - Notepad")
WinActivate($gGUIDummy)
ConsoleWrite("Sending..." & @CRLF)
;~ ControlSend($HWND, "", "", "!f") ;control Id 0 is the issue here
WinMenuSelectItem($hWnd,"","&File","&Save")
ConsoleWrite("sent..." & @CRLF)

I think as long as you use a valid dummy variable (not defined on the fly, EVER) it seems to work. no errors.

 

 

Can any of you mod's please move this topic to the development forum?

yeah, I think you were just feeding it garbage and not a null variable, so this actually makes sense. Did you check the @error? and extended error info when you don't allocate a variable before using it? This is probably not a bug IMO. You can't feed things garbage memory locations and expect things to work in any language.

Why? This looks like an AutoIt3 discussion.

i think this is working properly. You can't throw out an un-allocated memory address (pointer) at a function and not expect problems. that variable is just a pointer to memory somewhere.

Well, people tend to do a "Here, I fixed it..." instead of discussing is it a bag or not

Actually, if you look at my original post, I am sending a zero, not a variable.

You are right, we can't expect everything to work no matter what we trow at it.

I just wanted to point out an observation. Nothing critical.

good luck with your scripting. BrewMan had the correct answer first. You just had to WinActivate your Notpad instance and your original code works great.

$gGUIDummy = GUICreate("")
;~ MsgBox(1, "", "GUI Windows Handle is: " & $gGUIDummy)
Run("notepad.exe")

$HWND = WinWait("Untitled - Notepad")

WinActivate($gGUIDummy)
WinActivate($HWND)
ControlSend($HWND, "", 0, "!f") ;control Id 0 is the issue here

GUICreate was giving us a valid handle, checked it.

That code is showing how in certain condition the ControlSend is blocking further script execution.

You can't remove a part of code and say "Here! It doesn't block anymore!" XD
