A SDI project based on CView,for example ,named Test;a public member variable named speed(int type) in TestView.cpp,the project include a dialog resource,the dialog called by menu.

Now ,i want to transfer the variable:speed in the TestView.cpp to a variable in the dialog,how can i do?

You can pass it to a dialog when is instantiated, before calling DoModal or Create.
Or you can obtain it later from a view.
You have to have some means to access a view object. Another words you have to have a pointer or a reference to the instance of the view.
For example:
- you can obtain pointer to a view from a dialog by calling framework or supplied functions.
- you can pass pointer to a view to a dialog when dialog is instantiated
Having pointer to an instance you will be able to access public members of that object.
