Lu,

Did you find an answer to this one?

I tried using the same code but it doesn't give the right screen coordinates back.

Thanks!

So the method you're using is described in the documentation as converting a point on the page to pixels.  I think what you are after is to convert a map pt to a page pt?  If so, trying looking up the IDisplayTransformation interface's "FromMapPoint" method.

thank you for your answer,I have try, but it don't  work.when i input different map pt, but output the same page pt.why? this is my code:

IActiveViewPtr is PageLayout  property
void CPlotView::MapToLayoutview(IActiveViewPtr& pActiveview,double dMapX,double dMapY,int& iScrX,int& iScrY)
{
 IPointPtr ipMapPt(CLSID_Point);
 long X,Y;
 ipMapPt->PutCoords(dMapX,dMapY);
 IScreenDisplayPtr m_pScreendisp;
 pActiveview->get_ScreenDisplay(&m_pScreendisp);
 IDisplayTransformationPtr m_pDisplaytransfor;
 m_pScreendisp->get_DisplayTransformation(&m_pDisplaytransfor);
 m_pDisplaytransfor->FromMapPoint(ipMapPt,&X,&Y);
 iScrX=int(X);
 iScrY=int(Y);
}
