vc ++中的多个对话框 [英] multiple dialog in vc++

问题描述

你好，

我正在使用VC ++ 6.0 [基于MFC].我需要创建多个对话框，以使所有对话框同时处于活动状态.
使用无模式对话方法可以做到这一点吗?
如有可能，请以我为初学者的方式帮助我进行创建，并逐步说明操作步骤.

在此先感谢

推荐答案

Nitheesh George答案几乎是正确的.您只需要动态创建对话框对象，或使其成为类的成员，否则退出该函数后，该对话框对象将被销毁.

如果您希望动态创建对话框，则可以执行以下操作:

Nitheesh George answer is almost correct. You just need to create the dialog object dynamically, or make it member of a class, otherwise the dialog object will be detroyed as soon as you exit the function.

If you prefere to create the dialog dynamically, you can do something like:

CYourDialog* dlg = new CYourDialog();
dlg->Create(IDD_YOUR_DIALOG_ID, this);
dlg->ShowWindow(SW_NORMAL);

为了确保没有内存泄漏，一旦不再需要创建的对话框，还必须删除它.例如:

将此添加到对话框.h文件中:

And to make sure you don''t have memory leaks, you also have to delete the created dialog once it is not needed anymore. For example:

Add this inside your dialog .h file:

class CYourDialog
{
    ...
protected:
    virtual void PostNcDestroy();
    afx_msg void OnClose();
};

将此添加到对话框.cpp文件中:

Add this inside your dialog .cpp file:

BEGIN_MESSAGE_MAP(CYourDialog, CDialog)
    ...
    ON_WM_CLOSE()
END_MESSAGE_MAP()
...
void CYourDialog::PostNcDestroy()
{
    CDialog::PostNcDestroy();
    delete this;
}
void CYourDialog::OnClose()
{
    CDialog::OnClose();
    DestroyWindow();
}

请在下面找到示例，

CMyDialog dlg;
dlg.Create(IDD_DIALOG1，this);
dlg.ShowWindow(SW_NORMAL);

这将创建一个无模型的窗口，您可以与父窗口或任何其他顶级交互，并创建另一个没有问题的模型/无模式的窗口


希望对您有帮助

Hi,

Please find the sample below,

CMyDialog dlg;
dlg.Create(IDD_DIALOG1, this);
dlg.ShowWindow(SW_NORMAL);

this will create a modelless window you can interact with the parent window or any other top level and create another model/modeless window no probs


Hope this helps

您使用的是MFC还是Win32?

Are you using MFC or just Win32?
