像CDialogBar这种MFC提供的类要继承的话是不是只能手工加代码，而不能靠在classwizard里选择base class这种方法？

哪位高手能回答我一下？谢谢！

是！

微软也真是的，这个难度又不高，干嘛做成这样，自已改还是挺麻烦的。

这是我在别的帖子里的解答,转到这:

我摘要了九步列出来(例子就看上面的url吧)
1.Change the base class from CDialog to CDialogBar in the class declaration. Don't forget to also change the base class in BEGIN_MESSAGE_MAP in the .cpp file.
2.Change the constructor in both the .h and the .cpp files. Also make the change to the DoDataExchange(). Below are three items to change.
3.Remove "virtual BOOL OnInitDialog();" from the class header and add "afx_msg LONG OnInitDialog ( UINT, LONG );" in its place.
4.Add "ON_MESSAGE(WM_INITDIALOG, OnInitDialog );" to the message map in the .CPP implementation file
5.Make the OnInitDialog() conversion as the example(见例子)
6.Make sure the dialog box resource styles to the following:
Style: Child
Boarder: None
Visible: Unchecked
At this point, everything has been reconnected to make the transformation from a CDialog class to a CDialogBar class work correctly. Now, create and use it.
7.Add an instance of the derived CDialogBar to the CframeWnd-derived class (normally called CMainFrame).
8.Call the create method for the m_myDlgBar variable in the CFrameWnd::OnCreate() method
9.
Finally, you an support dynamic docking and resizing of the CDialogBar

其实这里涉及的一个问题就是如何从classwizzard列表里没有的基类派生新类.

那这样可真麻烦啊。

我采用的方法是基类选择CWnd，然后改成CDialogBar就行了。

你可以先继承cdialog,做完了你的wizard工作后,将cdialog改成cdialogbar
注意,构造函数是传给cdialog是没有参数的.
我试过,还是比较方便的.呵呵
