OLE Server Presentation Data Problem

Dear MFC Collective, 
 I generated my project  using AppWizard as a OLE Server.  It is basically a 
text editor.  We are using a third party MFC CView derived view for the RTF 
text.  I would like the presentation data to display the first page of the 
document.  I assume that this is done in  the CMySrvrItem::OnDraw(CDC* pDC, 
CSize& rSize) function.  Here is some what I am trying:

BOOL CMySrvrItem::OnDraw(CDC* pDC, CSize& rSize)  // Class is derived from 
COleServerItem
{
 CTeditDoc* pDoc = GetDocument();
 ASSERT_VALID(pDoc);

 pDC->SetMapMode(MM_ANISOTROPIC);
 pDC->SetWindowOrg(0,0);
 pDC->SetWindowExt(3000, 3000);

 /* Here's my code */
    
 POSITION pos=pDoc->GetFirstViewPosition();
 CThirdPartyRTFView *view = (CThirdPartyRTFView*)pDoc->GetNextView(pos); // get 
our view
 view->OnDraw(pDC);    

 /* End of my code */

 return TRUE;
}

I am getting a stack overflow even if the document consists of 3 lines.

Thank you very much for your help.

     Hi Timothy,
     
     You got a stack overflaw because you're calling CMySrvrItem::OnDraw 
     inside CMySrvrItem::OnDraw via the call 'view->OnDraw'. When in-place 
     activated, you're drawing into a metafile, there isn't a 
     CThirdPartyRTFView object around. 
     
     Normally you'd manually draw whatever the representation yourself 
     instead of delegating the task to your ThirdPartyView class.
     
     Hope this gives you some idea.
     
     -Bing.

I apologize for putting too many superflous details in my question last time.  
Thanks, Bing, for answering.  Here's goes:
I have a multiple paged ole text document.  I would like the OLE presentation 
data (a WMF) to display the first page.  
Is this possible?  Thanks a lot.

     Timothy,
     
     If I understand your question correctly, to tailor the OLE 
     presentation data to your like, you would draw the data in your 
     COleServerItem's OnDraw function. In your case, you'd copy the code 
     that draws the first page of the multiple-paged text document from 
     whereever to your COleServerItem's OnDraw function.
     
     If however the code cannot be copied, say it's a OLE control itself, I 
     haven't tried this myself, but you may create an instance of the 
     control in your CInPlaceFrame,(CInPlaceFrame::OnCreateControlBars may 
     be the place) and ask the control to draw the first page in the 
     CInPlaceFrame's space instead of using COleServerItem's drawing 
     function. Again, this is just a way to try if you don't have better 
     solutions.
     
     Hope this at least is relavent to what you asked.
     
     -Bing.
