Help with Win API function - Systemparametersinfo

4 posts in this topic

Afternoon (Well at least where I am ;))

I would love to be able to work with the SystemParametersInfo function in order to set "Adjust for best performance" (or really anything within this awesome function) within Windows XP (possibly with Vista and 7). But I'm sorely lacking in my WINAPI abilities... Any help would be GREATLY appreciated!

Here's a snippet from the WinAPIEx UDF (written by Yashied) that shows how to get the WorkArea using SystemParametersInfo.

Func _WinAPI_GetWorkArea()

    Local $tRECT = DllStructCreate($tagRECT)
    Local $Ret = DllCall('user32.dll', 'int', 'SystemParametersInfo', 'uint', 48, 'uint', 0, 'ptr', DllStructGetPtr($tRECT), 'uint', 0)

    If (@error) Or (Not $Ret[0]) Then
        Return SetError(1, 0, 0)
    EndIf
    Return $tRECT
EndFunc   ;==>_WinAPI_GetWorkArea

The number 48 in the DLLCall statement is used in place of SPI_GETWORKAREA from the MSDN page to get the information. Using that page and this snippet, I can only assume you should be able to get any of the other parameters using the appropriate value in place of the 48 in that line.

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.

Don't thank me, I only copied it from Yashied's work.

I used to homebrew, but the wife doesn't want the house to smell. ;)
