VC对话框启动时隐藏

这个问题其实网上有很多答案，但大多都不够简洁和完美，下面这个方法可能是最佳的。

 

首先要在资源中将对话框属性的Visible勾选去除。

修改项目App的实现文件，以笔者的一个名为AutoInstall的项目为例：

BOOL CAutoInstallApp::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

    CAutoInstallDlg dlg;
    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;
}

 

 修改为：

BOOL CAutoInstallApp::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

    m_pMainWnd = new CAutoInstallDlg;
    return ((CAutoInstallDlg *)m_pMainWnd)->Create(IDD_AUTOINSTALL_DIALOG);

    // Since the dialog has been closed, return FALSE so that we exit the
    //  application, rather than start the application's message pump.
    return FALSE;
}

 

由于程序运行后对话框根本不会显示，因此如果希望任务完成后自动退出，需要在程序中控制对话框自动关闭。

可以在OnInitDialog()返回的地方插入一句：PostQuitMessage(0);
