I'm having a problem with adding push button to a window.
It is MFC document/view application in which i have some drawing in OnDraw method and I want do add button bellow the drawing.
I'm trying with

m_wndPushButton.Create(_T("Button"), WS_CHILD | WS_VISIBLE, BS_PUSHBUTTON, CRect(100, 600, 200, 650), this, IDC_BUTTON);

I'm adding that code to view class. If I put it into constructor, nothing happens, if I put it into OnCreate, the same thing, if I try to put it at the end of OnDraw method, button shows but wen I click it or when I resize window I get Debug assertion failed (file: wincore.cpp, line:628).
