GetWindowHandle, nothing found doesn't set the result variable to 0

[Grovkillen]

I need to set the window handle to zero before running the GetWindowHandle command just to be sure that the value isn't from a previous check. I would expect the command to return zero if nothing is found.

Code: Select all

Let>WINDOW_HANDLE=0
GetWindowHandle>Window Title*,WINDOW_HANDLE

Well... apparently if no window is found the result is not set to anything. Since window handles are always a number, rather than presetting the result value to "0" I'd set it to a text value perhaps "BLANK" or even "ZERO". After the GetWindowHandle> function if the result is still set to the preset text, you'll know that no window was found.
