问题描述
CDialog和CDialogEx有什么区别?我决定使用CDialog,因为如果Dlg是从CDialogEx派生的,则无法将m_pMainWnd分配给Dlg.
What is the difference between CDialog and CDialogEx? I decided to use CDialog because I can't assign m_pMainWnd to Dlg if Dlg is derived from CDialogEx.
BOOL CPreparationApp::InitInstance()
{
MyClass2 Dlg; //derived from CDialog
m_pMainWnd = &Dlg;
Dlg.DoModal();
return TRUE;
}
如果不使用像表单向导那样的CDialogEx,我可能会遇到什么样的问题?

推荐答案
CDialogEX是从CDialog派生的,因此,将m_pMainWnd设置为CDialogEx派生的对象应该没有问题. CDialogEx提供了设置对话框的背景颜色或图像的能力.
CDialogEX is derived from CDialog, so, setting m_pMainWnd to a CDialogEx derived object should not be a problem. CDialogEx provides the abillity to set the background color or image of the dialog.
