Property Value retrieval in OCX

SBERTRAN.US.ORACLE.COM -- SBERTRAN@us.oracle.com

Environment: VC++ 2.0, Windows 95 
 
I am developing a common dialog OCX that contains properties, events, and 
methods.  I have a CDialog implementation for each common dialog in its own 
file.  The look and feel of these dialogs can be modified by changing the 
values of certain properties, but I cannot figure out how to retrieve and set 
the values of my properties from outside the COleControl class implementation. 
 
If you've been there before, please let me know at the below e-mail address.  
Many thanks in advance,

I hate to answer my own question, but I figured it out.  Many thanks to Tom 
Armstrong, I retrieved the following from the OLE Control FAQ at 
http://www.sky.net/~toma/faqprop.htm#DDP (note the disclaimer at the end of 
this message, retrieved from the site): 
 
"You can also get a pointer to your COleControl derived class by using the 
FromIDispatch method of CCmdTarget like this:  
 
   // Get the property page's IDispatch array 
   ULONG ulObjects; 
   LPDISPATCH* lpObjectArray = GetObjectArray( &ulObjects ); 
   ASSERT( lpObjectArray != NULL ); 
 
   // I'm assuming there is but one control, mine 
   LPDISPATCH lpControl = lpObjectArray[0]; 
 
  // Get a pointer to the control object 
   CMyCtrl* pControl = (CMyCtrl*) CCmdTarget::FromIDispatch( lpControl ); 
 
   // Call a public method in CMyCtrl 
   long x = pControl->SomeMethod( 100 );
