How to gain access to member variables of the control derived class from its property page when you use an ActiveX control

   // The header file of the control-derived class must be included in
   // the same source file.
   #include "myctrl.h"
  // This code is for versions prior to Visual C++ 2005. Comment out this code
  // when you are using the Visual C++ 2005 code.
   CMyCtrl* CMyPropPage::GetControlClass()
   {
     CMyCtrl *pMyCtrl;
     ULONG Ulong;

     // Get the array of IDispatch pointers that is stored in the property page.
     LPDISPATCH FAR *m_lpDispatch = GetObjectArray(&Ulong);

     // Get the CCmdTarget object that is associated with any one of the previous
     // array elements.
     pMyCtrl = (CMyCtrl*) CCmdTarget::FromIDispatch(m_lpDispatch[0]);

     // Cleanup
     return pMyCtrl;
   } 
   // This is the end of the code that is used for versions other than Visual C++ 2005.

   // The following code applies only to Visual C++ 2005. Uncomment this code for Visual C++ 2005. 
   CMyCtrl* CMyPropPage::GetControlClass() 
   {   
      CMyCtrl *pMyCtrl; 
      ULONG Ulong; 
      // Get the array of IDispatch pointers that is stored in the property page.
      LPDISPATCH FAR *m_lpDispatch = GetObjectArray(&Ulong); 
      // Get the CCmdTarget object that is associated with any one of the previous 
      // array elements.
      pMyCtrl = (CMyCtrl*) CCmdTarget::FromIDispatch(m_lpDispatch[0]); 
       if(NULL == pMyCtrl) 
       { 
           LPDISPATCH pDisp; 
           HRESULT hr = lpDispatch[0]->QueryInterface(IID_DTestActix,(void**)&pDisp); 
           ASSERT(SUCCEEDED(hr)); 
           pMyCtrl = (CTestActixCtrl *) CCmdTarget::FromIDispatch(pDisp); 
           pDisp->Release(); 
      } 
      // Clean up.
      return pMyCtrl; 
   } 
   // This is the end of the Visual C++ 2005-specific code.

   // If your control has a public member variable, you can manipulate that variable
   // as follows. (This code uses m_direct_control.)

   void CMyPropPage::OnLButtonDown(UINT nFlags, CPoint point)
      {
        // Directly modify a member variable of the Control class.
        CMyCtrl *pMyCtrl = GetControlClass();
        if (pMyCtrl)
        {
           pMyCtrl->m_direct_control++;
 
           // Display the new value of the variable in a message box.
           char buf[100];
           AfxMessageBox (_itoa (pMyCtrl->m_direct_control, buf, 10));
        }
 
        COlePropertyPage::OnLButtonDown(nFlags, point);
      }
				

CPropPageAccessCtrl::CPropPageAccessCtrl()
{
    InitializeIIDs(&IID_DPropPageAccess, &IID_DPropPageAccessEvents);

// New code.
// No aggregation, please!  
    m_xInnerUnknown = 0; //Base class COleControl. Set this by using a call to EnableAggregation().
//End of new code.
