Winhandle and resolution (Help)

4 posts in this topic

Does anyone see an issue with this code or does anyone believe it will not work on every PC.

Func Window_Resolution()    
If WinExists ( "My window", "") Then    
$hWnd = ControlGetHandle("My window", "", "")
$sHWND = String($hWnd)  
Iniwrite("My.ini", "Settings", "WinHandle", $sHWND)
EndIf   
EndFunc

I am using the windhandle to retrieve pixel colors from it.

Example:

PixelGetColor($X, $Y, $sHwnd)

Is the way I am doing this reliable?

For one thing, if you copied and pasted the PixelGetColor line then, the variable for the handle is incorrect. It should be "$sHWND" instead of "$sHwnd" as those are two different variables. Also, if using the variable outside of your function, then I believe you need to make the variable global. For this, use "Global $sHWND = String($hWnd)".

I cannot answer as to if it is very reliable as I am fairly new to AutoIt myself but, it works for me. :huh2:

It should be "$sHWND" instead of "$sHwnd" as those are two different variables.

Just an FYI, $sHWND and $sHwnd are the same variable, variable names aren't case sensitive in AutoIT.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

That's strange. I once was told opposite. Oh, well... live and learn. :huh2:
