MFC creating non-modal child windows

In the first window, create a second window with the following code:

#include "second.h"//second window header file void Ctestdlg::onbnclickedbutton6 () {Seconddig *pdig = new Seconddig;      Pdig->create (Idd_second);  Pdig->showwindow (SW_SHOWNORMAL); }

If you want to destroy a child window in the second window. The following two virtual functions are handled first, as follows:

void Seconddig::P Ostncdestroy () {//TODO: Add private code here and/or call base class CDialogEx::P Ostncdestroy ();  Delete this;       } void Seconddig::oncancel () {//TODO: Add the dedicated code here and/or call the base class DestroyWindow ();  Cdialogex::oncancel (); }

Rewrite the above two virtual functions. If the button is complete, call OnCancel () in the button click Message or use the following code

Exit the entire program:

PostQuitMessage (0);//or//afxgetmainwnd ()->sendmessage (wm_close,0,0);
