To get the usable desktop area, use SystemParametersInfo()...

' hDlg, dx & dy are the DDT dialog metric's.... psuedo code follows:
DIM Rct as RECT
SystemParametersInfo %SPI_GETWORKAREA, 0, BYVAL VARPTR(Rct), 0
' Now convert the values into DDT units...
DIALOG PIXELS hDlg, Rct.nLeft,  Rct.nTop    TO UNITS Rct.nLeft,  Rct.nTop
DIALOG PIXELS hDlg, Rct.nRight, Rct.nBottom TO UNITS Rct.nRight, Rct.nBottom
' Now centre the dialog in the true desktop area...
DIALOG SET LOC hDlg, Rct.nLeft + (Rct.nRight - Rct.nLeft - dx) / 2, Rct.nTop + (Rct.nBottom - Rct.nTop - dy) / 2

By using all 4 RECT parameters, it's possible to center your window in the usable desktop space, instead of the center of whole screen. ie, try making your taskbar very large and see how your program reacts without taking the taskbar into effect... some app's look positively horrible is the taskbar is ignored (ie, the taskbar may be displayed over the top of your dialog).

Beautiful, thank you!


Working on a setup program, needed the "Normal" setup look for the gradient blue screen..

How does one capture what screen resolution the Computer is set to?

nScreenWidth = GetSystemMetrics( SM_CXSCREEN )
nScreenHeight = GetSystemMetrics( SM_CYSCREEN)

This does not appear to return a valid size...

Local wndclass As WndClassEx

GetWindowRect %HWND_DESKTOP, WndRect

Thanks,
