Insert block with block attached to mouse.

This will solve the problem. It starts the drag/drop operation as if the user drags the block onto the drawing. Written here in C#.<br /><br />private void AttachBlockToMouse(string blockFile)<br />        {<br />            string[] fList = new string[1];<br />            fList[0] = blockFile;<br />            DataObject dataObj = new DataObject(DataFormats.FileDrop, fList);<br />            dataObj.GettingData += new EventHandler<EventArgs>(dataObj_GettingData);<br />            DragDropEffects eff = DoDragDrop(dataObj, DragDropEffects.Link | DragDropEffects.Copy);<br />        }
