gui adjustments

5 posts in this topic

#1 ·  Posted (edited)

anyone knows of a to date function UDF that will help adjusting the gui to scale correctly with labels, font sizes.. (for different desktops/dpi)
 
I found this topic

I tried to run it with the example but it errors in scite :

$hDC = DllCall("user32.dll", "long", "ReleaseDC", "long", $hWnd, "long", $hDC)

(56) : ==> Variable used without being declared.:

and it seems to be declared :huh:

 

Thanks

Run it like this. Don't know if that is really what you are looking for though...

 thanks kylomas

so it will only get the dpi for the gui and controls but wont help doing the conversions for re-sizing things around .. it seems like a good  formula 
 
so I'm guessing anything like this can be done only after learning winapi and  _GDIPlus calls 
strange there is no simple UDF for this yet ;)
