用MFC编好对话框想在启动时首先打开登录对话框，用VC6.0程序运行没有错误，但是就是不能执行 。

方法一是在主对话框的OnInitDialog里调用登录对话框
代码：
BOOL CFingerDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
// TODO: Add extra initialization here
Login gin; //调用登录对话框
if(gin.DoModal()!=IDOK)
OnOK();
return TRUE; // return TRUE unless you set the focus to a control
}更多0

程序调试没出错，但是就执行的时候，不弹出任何窗口。求大神帮帮忙，指点一下

还尝试了第二方法在InitInstance()中改
代码：
BOOL CFingerApp::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
CLogin dlg; //改为登录对话框
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}

依然是没有出错，但不弹出对话框

哥们 你能把你的程序发给我吗 今年大一 想学一下怎么建立多对话框

这个很简单的，祝窗口初始化时隐藏主窗口然后打开登陆窗口
