Child Windows In Other Apps Under Vista

Recommended Posts



I have been playing with Volly's old SciTE toolbar (you can find it here if you are interested) and I have run into problems setting it as a child window within SciTE. I am running Vista Home Premium SP1.

Volly's code uses the following to create the toolbar window:

Global $Scite_Hwnd = WinGetHandle("classname=SciTEWindow")
Global $My_Hwnd = GUICreate("SciTE interface", 100, 18, Default, Default, $WS_POPUP, $WS_EX_TOOLWINDOW, $Scite_hwnd)

When I run from within SciTE this poses no problem and I get a nice child window, but disaster follows when trying to run the compiled code. All windows begin to flash and gradually become unresponsive. The only way to break out is to log off. I have played with the code and it seems to be the "parent" parameter in GUICreate that is causing the problem.

As no-one reported this when Volly was developing his code (he ceased development in 2006), I can only presume that it is a Vista (sigh!) thing and that the OS does not like you trying to create child windows within another application. Any confirmation of this hypothesis or suggestions as to how to get around the problem?

Of interest, I am at present using a compiled script which creates the toolbar with $WS_POPUP, $WS_EX_TOOLWINDOW + $WS_EX_TOPMOST styles and then hiding it when the SciTE window is not active. This works quite well - but it is a bit disconcerting to see the toolbar vanish and reappear from time to time!

Any thoughts welcome - actual help would be better!
