Duplicate Interface Names Across different components

Question

0.00/5 (No votes)

See more:

My Visual Studio solution has around 10 projects. Each project has different target and some projects use output of other projects. Most of the projects are ActiveX components represented by DLLs. Each project has its own set of interfaces. I want to define new interfaces in ProjectB but want to keep the interface name same ( but different CLSID) as the one used in ProjectA. The project A uses output of ProjectB. When I build the solution, I get compilation errors indicating re-definition. How this isssue can be resolved? Is it practical or not? I think it is quite practical because an application may use components from diffrent vendors and each vendor develops component without bothering about keeping the unique names but ensuring unique id. But how to resolve compilation issues ?

Solution 1

If the interfaces are defined in speparate namespaces it shouldn't matter. You have to make sure though that when one class uses both interfaces they would have to be fully qualified.

I hope I expressed it clearly.

Modification: After all namespaces were especially made for resolving naming conflicts.End of modification

Cheers,

Do .idl files have namespaces ?

yep, just fully qualify - but Manfred was (again) faster with his answer. @ Manfred - thumbs up!
