Made a ocx in Delphi, in another Delphi procedure calls, it's no problem, can display the selected normal (control prototype TDrawGrid) :



Code:


OCX when making key code is as follows:

Note: implementation has add attribute SelectionRect: property SelectionRect: OleVariant read Get_SelectionRect write Set_SelectionRect;


Above is in Delphi ocx development, and use this ocx in Delphi, no problem, ok, problem is coming, to call in c #, but error:


Is the type used wrong?
