// file IButtonCallback.h
class IButtonCallback {
public:
   virtual void OnForm2Button1Pressed() = 0;
};

// file mainwnd.h
#include "IButtonCallback.h"
class MainWnd : public CWnd, IButtonCallback {
   // ...
   void OnForm2Button1Pressed();
};

// file mainwnd.cpp
MainWnd::MainWnd(/*...*/) { // constructor
   form2.SetCallback(this);
   // ...
}
void MainWnd::OnForm2Button1Pressed() {
   form1.SetText(_T("Button pressed!"));
}

// file form1.h
class Form1 : public CWnd {
   // ...
   void SetText(TCHAR* text);
};

// file form2.h
#include "IButtonCallback.h"
class Form2 : public CWnd {
   // ...
   void SetCallback(IButtonCallback* cb);
   void OnButtonPressed();
private:
   IButtonCallback* m_cb;
};

// file forms.cpp
void Forms::SetCallback(IButtonCallback* cb) {
   m_cb = cb;
}
void Form2::OnButtonPressed() {
   m_cb->OnForm2Button1Pressed();
