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 CMcbWindow
CMcbWindow 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 CMcbWindow
class CMcbWindow : public CWindowImpl<CMcbWindow>
{
// START MESSAGE_MAP
BEGIN_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.
