You should be able to adapt the example code here to do what you want:

MSDN: Initializing a dialog box

I do it with a Dialog Box app. In the resource editor properties for the dialog resource, set Border=None and Title Bar=False to eliminate all border elements. In OnInitDialog, use the following to resize the dialog to the entire desktop:

CRect rcDesktop;
rcDesktop.left = GetSystemMetrics(SM_XVIRTUALSCREEN);
rcDesktop.right = rcDesktop.left + GetSystemMetrics(SM_CXVIRTUALSCREEN);
rcDesktop.top = GetSystemMetrics(SM_YVIRTUALSCREEN);
rcDesktop.bottom = rcDesktop.top + GetSystemMetrics(SM_CYVIRTUALSCREEN);
MoveWindow(rcDesktop, FALSE);

This code works on multiple monitors, unlike maximizing the window.

No need to worry about making the window topmost, Windows will display it on a dedicated desktop with no other windows present.

I think removing the border from the dialog resource and showing the window as maximized (ShowWindow(SW_SHOWMAXIMIZED)) should do the job.

As for topmost use the System Modal style in the dialog resource.
