Is this possible?

I have a dialog box (CDialog1) that has a few buttons and a list control.  Now I have another Dialog Box (CDialog2) that has the same items plus one more list control on it.  Is it possible to derive Dialog2 from Dialog2??  Do I have to name the controls the same?  The two dialog boxes do the same thing except CDialog2 has one more control, I am trying to avoid writting the same code for both dialog boxes.  Thanks.

Have a look at control subclassing in the online-help. Perhaps you can drive the class for the second dialog from the class for dialog1 or create a base class for both dialogs.

The solutoion for meetze has nothing to do with control subclassing. meetze's needs can be addressed with C++ subclassing.

Yes .. you can do this.  As long as the control id's are the same it is pretty easy .. just add the extra code for your extra controls.

Unfortunately it is not easy to have your disloag reousrces inherit from each other .. they will have to remain copies.  But inheriting one CDialog-derived class from another (instead of directly from CDialog) works well .. I use it all the time.

The solution to your problem seem to be:

class CDialog1 : public CDialog
{
   public:
       CDialog1();
   private:
       CControl1   *m_pCont1;
};

class CDialog2 : public CDialog1
{
   public:
      CDialog2();
   private:
      CControl   *m_pCont2;
};


Here the second object is derived from the first.
