Здравствуйте, Denis Titov, Вы писали:

DT>Вообще-то, OleDraw просто IUnknown требует а не IViewObject. Или я чего не понял?

К сожалению требует

Remarks
The OleDraw helper function calls the QueryInterface method for the object specified (pUnk), asking for an IViewObject interface on that object. Then, OleDraw converts the RECT structure to a RECTL structure, and calls IViewObject::Draw as follows:

lpViewObj->Draw(dwAspect,-1,0,0,0,hdcDraw,&rectl,0,0,0);
