不使用ATL向导,创建一个简单的ATL对话框程序.

本例使用CWindowImpl类创建对话框程序.第一步:建立一个新的Win32 Application工程.

第二步:在stdafx.h中包含下面三行.     

#include <atlbase.h>extern CComModule _Module;#include <atlwin.h>

第三步:写WinMain函数,如下:     

int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE, LPSTR, int ){_Module.Init( NULL, hInstance );

// Create an instance of CMcbWindowCMcbWindow atlWnd;atlWnd.Create( NULL, CWindow::rcDefault, _T("Mahesh's ATL Window"),WS_OVERLAPPEDWINDOW|WS_VISIBLE );

MSG msg;while( GetMessage( &msg, NULL, 0, 0 ) ){TranslateMessage( &msg );DispatchMessage( &msg );}

_Module.Term();return msg.wParam;}第四步:从CWindowImpl继承CMcbWindow类:

// NOTE: See the template parameter. Its CMcbWindowclass CMcbWindow : public CWindowImpl<CMcbWindow> {// START MESSAGE_MAPBEGIN_MSG_MAP( CMcbWindow )MESSAGE_HANDLER( WM_PAINT, OnPaint )MESSAGE_HANDLER( WM_DESTROY, OnDestroy )END_MSG_MAP()// END MESSAGE_MAP

// This function will paint a Hello mindcracker string LRESULT OnPaint( UINT, WPARAM, LPARAM, BOOL& ){PAINTSTRUCT ps;HDC hDC = GetDC();BeginPaint( &ps );TextOut( hDC, 0, 0, _T("Hello mindcracker"), 17 );EndPaint( &ps );return 0;}

LRESULT OnDestroy( UINT, WPARAM, LPARAM, BOOL& ){PostQuitMessage( 0 );return 0;}};第五步:定义CComModule _Module:

// ATLWnd.cpp : Defines the entry point for the application.#include "stdafx.h"CComModule _Module;最后:编译执行.
