DDX_Control and DDX_Text

[derek7]

what is different between them?

[mbue]

Use your SDK manual. I think DDX_Control subclasses the given control and DDX_Text exchanges the text.

[derek7]

what does subclasses mean? it mean use a subclass to override the base class?

[mbue]

Subclassing in this case is: to attach the control or window to a given class (for instance: CButton). This class will handle all events for that window.

Is sub ab. of substitute?
