"text size" changed from default 100% causing GUI problems

3 posts in this topic

Unfortunately I've found that my input boxes and combos are getting truncated if users change their text size from the default 100% by "screen resolution" -> "make text and other items larger or smaller" (or Control PanelAll Control Panel ItemsDisplay) and selecting medium or larger. This seems to even alter how much text can be stored in the GUI fields by truncating them.

Is there any way I can easily set the "make it easier to read what's on your screen" setting to 100% during script execution and put it back upon close please?

You can set the control size depending on the DPI.

I use this GDI+ function to get the DPI size:

Func _GDIPlus_GraphicsGetDPIRatio($iDPIDef = 96)

    Local $hGfx = _GDIPlus_GraphicsCreateFromHWND(0)

    If @error Then Return SetError(1, @extended, 0)

    Local $aResult = DllCall($ghGDIPDll, "int", "GdipGetDpiX", "handle", $hGfx, "float*", 0)

    If @error Then Return SetError(2, @extended, 0)

    Local $iDPI = $aResult[2]

    _GDIPlus_GraphicsDispose($hGfx)

    Local $aResults[2] = [$iDPIDef / $iDPI, $iDPI / $iDPIDef]

    Return $aResults

EndFunc ;==>_GDIPlus_GraphicsGetDPIRatio

According the information you can set the size of your control or the font size.

Thank you.

Apparently "$ghGDIPDll" been renamed in the GDIPlus UDF, so from the GDIPlus startup function, its new name is $__g_hGDIPDll and I think the function needs "If Not $__g_hGDIPDll Then _GDIPlus_Startup()" at the beginning and "_GDIPlus_Shutdown()" at the end (and the includes for GDIPlus).

If there has been no change to the PC's "size of text" from the default 96dpi (100%) then this function returns array value [1, 1].
