1. 完全全屏
在OnInitDialog() 方法中調用如下代碼:

m_bFullScreen = FALSE;
CDialog::OnInitDialog();

 // Call SHInitDialog with flags for full screen.
 SHINITDLGINFO shidi;

 shidi.dwMask = SHIDIM_FLAGS;
 shidi.dwFlags = SHIDIF_FULLSCREENNOMENUBAR;
 shidi.hDlg = m_hWnd;
 ::SHInitDialog(&shidi);

 // TODO: Add extra initialization here.
 //::CommandBar_Show(m_pWndEmptyCB->m_hWnd, FALSE);

 // SHFullScreen fails if dialog box is not foreground.
 SetForegroundWindow(); 
 SHFullScreen(m_hWnd, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON);

 // Resize the window over the taskbar area.
#define MENU_HEIGHT 26
 RECT rect;
 GetWindowRect(&rect);
 rect.top -= MENU_HEIGHT;
 MoveWindow(&rect, TRUE);

上面一段代碼可以實現(xiàn)完全的全屏, 但是我使用的過程中發(fā)現(xiàn)對話框的標題欄消失了..不知道為什么..

2. 客戶區(qū)全屏

 CHikConfigDlg configDlg;

 CRect rc;

 SetRect( &rc, 0, 0, GetSystemMetrics( SM_CXSCREEN ), GetSystemMetrics( SM_CYSCREEN ) );

// 用來隱藏菜單欄的

 //HWND hCommandBarWnd = ::FindWindowW( _T("menu_worker"), NULL );

 //::CommandBar_Show(hCommandBarWnd, FALSE);

 ::SHFullScreen( configDlg.m_hWnd, SHFS_HIDETASKBAR | SHFS_HIDESTARTICON | SHFS_HIDESIPBUTTON );

 ::MoveWindow( configDlg.m_hWnd, rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top, FALSE );

 INT_PTR nResponse = configDlg.DoModal();

 if ( nResponse == IDOK )
 {

 }
