Question

Is there a method on a DgnButtonEvent to accomplish the same thing? 
 UpdatePosition(DgnButtonEventCR ev)
{
	DPoint3d screenPt3D = { 0 };
	ev.GetViewport()->ViewToScreen(&screenPt3D, ev.GetViewPoint(), 1);	// Transfrom an array of points in DgnCoordSystem::View into DgnCoordSystem::Screen.
	Point2d globalPt = { (int)screenPt3D.x, (int)screenPt3D.y };
	Point2d screenPt2d = { 0 };

 // Can I do this somehow directly without calling mdlWindow_globalPointToScreen() ?
	mdlWindow_globalPointToScreen(&screenPt2d, mdlWindow_viewWindowGet(ev.GetViewNum()), &globalPt);	// Converts a point in global coordinates to a point in screen coordinates for the screen number specified by windowP.
}

That is what I'm currently doing. You have confirmed my suspicions:

 Thanks !!

// note: you can use the following corrected code piece to get pure windows screen point for the button event. 
 // both pointInMDLclient and globlePoint are in a window coordinates which is relative to a window rect. 
 // as you said, Viewport::ViewToScreen don't return screen point in fact. 
 // please focus on the using of mdlWindow_globalPointConversionIncrease which is the key point here. 
 // other changes just rename the variable names to make it's meaning more accurate. 
 //

// ev.GetViewPoint returns the mouse position of client area of the view window, 
 // Viewport::ViewToScreen returns the point which is relative to left-up corner of a special client window which 
 // is the gray area to contain the 8 view windows. The special client window is like the Win32 
 // MDClient for multi-document program. 
 // 
 DPoint3d pointInMDLclient3D = { 0 }; 
 ev.GetViewport ()->ViewToScreen (&pointInMDLclient3D, ev.GetViewPoint (), 1); 
 Point2d pointInMDLclient = { (int)pointInMDLclient3D.x, (int)pointInMDLclient3D.y }; 
 
 // in CE, because there is ribbon bar, we must convert the pointInMDLclient to global point which is relative to 
 // the left-up corner of the main frame window. 
 // 
 Point2d globlePoint = { 0 }; 
 MSDialogP viewWindow = mdlWindow_viewWindowGet (ev.GetViewNum ()); 
 if (mdlWindow_isGlobalPointConversionRequired (viewWindow->GetScreenNumber ())) 
 mdlWindow_globalPointConversionIncrease (&globlePoint, viewWindow, &pointInMDLclient); 
 else 
 globlePoint = pointInMDLclient; 
 
 // now use mdlWindow_globalPointToScreen to convert the global point to screen point which is pure windows concept 
 // but not the Microstation concept, and I don't think there is equivalent C++ method in DgnButtonEvent or other class 
 // 
 Point2d screenPt2d = { 0 }; 
 mdlWindow_globalPointToScreen (&screenPt2d, mdlWindow_viewWindowGet (ev.GetViewNum ()), &globlePoint);
