"OleCreate" 0x80040154 Eorror when used ActiveXControlComponent

Hi,everybody.

I use ActiveXControlComponent to load a ActiveX obj. I found that the function OleCreate used in ActiveXControlComponent::createControl returned error - 0x80040154 - "Class is not registered".

I had registered the ActiveX obj in fact.

 

Could someone have some idea ? Thanx.
