Create CWnd problem

[TOMNKZ]

hi.
i create cwnd derived class.

Create(NULL,_T("Errors"),WS_CHILD|WS_CAPTION|WS_MAXIMIZE|WS_MINIMIZE|WS_OVERLAPPED,CRect(100,100,500,500),&CWnd(GetDesktopWindow()),0);

In OnCreate of this window i create CListCtrl and button.

But when i call ShowWindow(SW_SHOW), i see my window icon in task bar,but when i press it,i see window area with copy of my desktop screen,why?

i think you need to supply WS_VISIBLE flag to the Create function

I do not see what are you creating (calling Create member of what class)?
Does your code compile? I have doubt: &CWnd(GetDesktopWindow())
Is your code snippet verbatim?
You also create window that is a child of the desktop window. It is also created without background brush since Windows is using default window class. You should register your own.

I find solution for my problem.

I create window in dll,so it lead to problems. Solution was to create not modal dialog, which parent can be NULL.

Thank you for interest.
