BOOL CXXXXApp::InitInstance()

//以下检测是否有运行着的实例，若有就退出
HANDLE hMutex = ::CreateMutex( NULL, TRUE, m_pszAppName );

if ( ::GetLastError() == ERROR_ALREADY_EXISTS )

return FALSE;

pFrame->LoadFrame(IDR_MAINFRAME,

WS_OVERLAPPEDWINDOW,/*这里去掉了FWS_ADDTOTITLE（负责往TITLE加document名称）*/

NULL);

//以下更改TITLE图标

HICON hIcon=AfxGetApp()->LoadIcon(IDI_ICON1);

ASSERT(hIcon);

m_pMainWnd->SendMessage(WM_SETICON,TRUE,(LPARAM)hIcon);

// m_pMainWnd->SetWindowText("在这里可以改变TITLE名称");

// The one and only window has been initialized, so show and update it.

pFrame->ShowWindow(SW_SHOW);
