CFrameWnd that overlaps the Start Menu when maximized !

Hi !

I created a CFrameWnd usign this code :

CreateEx(0, wClass, "test", WS_MINIMIZEBOX|WS_MAXIMIZEBOX|WS_SYSMENU|WS_THICKFRAME|WS_CLIPCHILDREN|WS_VISIBLE|WS_POPUP, 20, 20, 520, 560, NULL, NULL, NULL);

I didn't specify WS_CAPTION cause I don't want my window to have a caption.

Everything was fine until I try to maximize the window usign :

ShowWindow(SW_MAXIMIZE);

The result is weird : the window takes up all the screen, overlapping the Start Menu !!!  Is there a way I can go around that strange behavior without adding a caption to my window ?

Thanx

You need to handle the WM_GETMINMAXINFO message. That'll give you the opportunity to specify exactly the size you want your window to have when it's maximized.  You can measure the screen your application is on by using the GetSystemMetrics() APIs.

See the FULLY.ZIP sample at http://www.nwlink.com/~mikeblas/samples/ for a program that does both of those things.

Is WS_POPUP appropriate? Have you tried removing it?

When I remove the WS_POPUP style, my window has a caption.  But thanks for the help anyways.  I finally could find what the problem was.  I had to make a little tweak in the OnGetMinMaxInfo callback :

void CMyFrameWnd::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
      CFrameWnd::OnGetMinMaxInfo(lpMMI);

      CRect r;
      SystemParametersInfo(SPI_GETWORKAREA, 0, &r, SPIF_UPDATEINIFILE);

      lpMMI->ptMaxSize.x = r.Width();
      lpMMI->ptMaxSize.y = r.Height();
      lpMMI->ptMaxPosition.x = r.left;
      lpMMI->ptMaxPosition.y = r.top;
      
}

This does exactly what I needed !
