CButton* btnApply = new CButton;
CRect recto;
GetClientRect(&recto);
ScreenToClient(&recto);
btnApply->Create((LPCTSTR)"Apply", WS_CHILD | WS_VISIBLE, recto,this, 1234);
btnApply->ShowWindow(SW_SHOW);

The button control is not displayed. What is the problem in the above code?

[Moved "answer" to comment:]
It does not look as C++/CLI. It is not. This is all regular C++ and native unmanaged code (or a fragment in mixed-mode project). Please change the tag or provide C++/CLI code.

You should not call ScreenToClient there. The rect you pass is in the coordinates relating to the parent window. And you've already called GetClientRect on the parent window. Of course this will basically create a button that fills your entire parent window (but perhaps that is what you want?)

Thanks. I am just starting my first MFC Application (UI Part). My ultimate aim : "How to position the controls in dialog box at runtime? (My controls will be created runtime and the number of controls vary everytime)."

Yeah, then use a rect relative to the top, left of the parent window.

Something like CRect(10, 10, 50, 30) should work well.
