如何让单文档窗口初始化时最大化？

[guanxg]

我要求我的单文档的窗口在初始化时要最大化，我在
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)函数中加了如下代码：
cs.style = WS_OVERLAPPEDWINDOW | WS_MAXIMIZE;
也试过cs.style = cs.style | WS_MAXIMIZE;
都不可以。
我记得可以通过设置cs.style达到要求，而且不是通过修改cs.cx,cs.cy，但是忘了怎么弄了。请各位帮忙！

先说窗口。
在 InitStance 函数中设定 m_nCmdShow的取值.
m_nCmdShow=SW_SHOWMAXMIZED //最大化
m_nCmdShow=SW_SHOWMINMIZED //最小化
m_nCmdShow=SW_SHOWNORMAL //正常方式

MDI窗口:
如果是创建新的应用程序,可以用MFC AppWizard 的Advanced 按钮并在MDI子窗口风格组中检测最大化或最小化还可以重载 MDI Window 的PreCreateWindow函数，设置WS_MAXMIZE or WS_MINMIZE

如果从 CMDIChildWnd派生,调用 OnInitialUpdate函数中的 CWnd::Show Window来指定 MDI Child Window的风格

BOOL CPracticeApp::InitInstance()
{
AfxEnableControlContainer();

// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.

#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif

// Change the registry key under which our settings are stored.
// TODO: You should modify this string to be something appropriate
// such as the name of your company or organization.
SetRegistryKey(_T("Local AppWizard-Generated Applications"));

LoadStdProfileSettings(); // Load standard INI file options (including MRU)

// Register the application's document templates. Document templates
// serve as the connection between documents, frame windows and views.

CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CPracticeDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CPracticeView));
AddDocTemplate(pDocTemplate);

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
return FALSE;

// The one and only window has been initialized, so show and update it.
m_pMainWnd->ShowWindow(SW_SHOW);//在这里改个标志就OK了。：）
m_pMainWnd->UpdateWindow();

return TRUE;
}

YourApp::OnInitialUpdate最后加上

m_pMainWnd->ShowWindow(SW_MAXIMIZE);

[fingerfox]

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.x = 0;
cs.y = 0;
cs.cx = GetSystemMetrics(SM_CXSCREEN);
cs.cy = GetSystemMetrics(SM_CYSCREEN);
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

return TRUE;
}
