I have imported an ActiveX in the Delphi IDE. Now if I start a new blank project and place this ActiveX on its form and run it (by pressing F9) it runs and the ActiveX behaves as documented. But when I use this ActiveX in an existing project I keep getting this message. What must be the problem? Can you give me code snipper as to how to call CoInitialize and CoUnInitialize? TIA Yogi Yang
