Re: Get MDI client area?

Where are you calling the dialog box from? Is you event handler to bring up
the dialog box in the CMainFrame?
If so I would simply get the rectangle before you call DoModal and pass it
to the dialog.

If for some reason you don't want to do that, then you can do this:

void CMDIArrangeDlg::GetMDIClientRect()
{
int nCaptionHeight=GetSystemMetrics(SM_CYCAPTION),
nEdgeThickness=GetSystemMetrics(SM_CYSIZEFRAME),
nMenuHeight=GetSystemMetrics(SM_CYMENU);

// Get the MDI client area
CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
::GetClientRect(pFrame->m_hWndMDIClient,&m_rectPos);

// Subtract height of title bar and width of edge * 2
m_rectPos.bottom-=((nEdgeThickness*4)+nCaptionHeight+nMenuHeight);
m_rectPos.right-=((nEdgeThickness*4));
}

But I highly encourage you to put your handler for the dialogbox in the
frame class, and pass the rect into the constructor of the dialog.
