I mean to say that the second dialog should appear like other controls in that main dialogbox.

How ?

m_Preview.Create(IDD_MYDAILOG,0);//without WS_CAPTION
m_Preview.ShowWindow(1);

You might also consider using string instead of CString

Is string actually faster? Do you know of any benchmark results? I've got a couple classes in an application that use CString heavily, and wonder if string would improve their performance.

These APIs r complicated. Better u use CRT functions.

WCHAR wcPath[MAX_PATH];
