I need to replace an ActiveX control with a new one for use in

0

I need to replace an ActiveX control with a new one for use in an existing application, without modifying the existing application.

I have the original ocx file and the code for the wrapper class that creates and uses the ActiveX control in the existing application.

I have created a test console app in VS 2005, using the wrapper class from the existing application, which can create and use the old ActiveX control.

I have created a new ActiveX control with the same interface as the old, modified all the Class Ids to match and registered the new ocx. The new control can be created, but on calling any of the methods I get a Catastrophic failure with error code 7fff0001.

I took a step back and created another new ActiveX control with the same interface, but didn’t modify the Class Ids. I then built a new test console app using the wrapper class and compiled it for this new control. But I still get a Catastrophic failure when calling the control’s methods.

I have searched for an answer, but most refer to problems calling ActiveX methods from managed c# applications and don’t provide any help for my situation.

Please see the code for the wrapper and ActiveX control import files below, any help would be appreciated thanks.
