to display dialog box?

推荐答案

你不能那样使用它（你的程序会崩溃）。您可以这样使用它：

You can''t use it that way (your program will crash). You may use it this way:

// Allocate CDialog object on the heap.
// Object must be destroyed when no longer needed.
CDialog *pDlg = new CDialog;
pDlg->DoModal();
delete pDlg;

// Allocate CDialog object on the stack.
// Object is destroyed when going out of scope.
CDialog dlg;
dlg.DoModal();
