dotnet interop : Problems registering C# COM object manually
Whenever I try to use the class (in the normal C++) from the COM object
I get the "Class not registered" error. I have tried to register the object with commands "regasm.exe MyModule.dll" and "regasm.exe MyModule.dll /codebase" but neither of them doesn't work. What is the correct way to register C# COM object class manually?
Hello,
The correct way to register the C# assembly for interop is, 1. to put the assembly in GAC and register it. 2. to put anywhere other than GAC and register with /codebase option. For your problem, it seems that you will have to register the assembly with /tlb option like, regasm.exe /codebase /tlb <assemblyname> And import that TLB file while compiling your application. Let me know if that does not work. regards, jigar [quoted text, click to view] On Nov 23, 1:27 pm, miikka.laa...@kaannos.com wrote:

Hi
I have imported the typelibrary and actually I don't have any problems with it on my developing machine, but when I try to use it in my testing machine (x64) it says that the "Class it not registered". I should have all needed dlls, and all other dlls are registered properly. My dlls reside on different path than the executable, but shouldn't codebase attribute solve this? My dll is not used for general purposes, so it might not be wise to install it to GAC? Jigar Mehta kirjoitti: [quoted text, click to view] > Hello,

Hello,
Can you try registering your C# component on deployment box with /tlb option? ============= Regards, Jigar Mehta [quoted text, click to view] > Hi > > I have imported the typelibrary and actually I don't have any problems > with it on my developing machine, but when I try to use it in my > testing machine (x64) it says that the "Class it not registered". > > I should have all needed dlls, and all other dlls are registered > properly.

Hi
With the win 32 (development) machine I can register the C# Com object with command "regasm MyModule.dll /tlb:/my/typelib/path /codebase" without any problem. There has been different dll versions of the same module on the test machine (x64) which might not be unregistered properly. Is there way to clean registry from these false entries?

Hello,
Yes, you can use regasm /u <assembly name> OR regasm /unregister <assembly name> for unregistering the assembly. ============= Regards, Jigar Mehta [quoted text, click to view] > Hi > > With the win 32 (development) machine I can register the C# Com object > with command "regasm MyModule.dll /tlb:/my/typelib/path /codebase" > without any problem. > > There has been different dll versions of the same module on the test > machine (x64) which might not be unregistered properly.

Hi
I unregistered everything and added the assembly to the GAC, still the problem remains. Is there some different situations than class is not really registered that might cause "Class not registered" error message (for example some needed module is missing etc.)?

Hello,
If you unregistered and then re-registered, then also the problem persists, then I think there is possibility that your TLB file (on the development machine is not lilnked to the latest TLB file.. Can you tell me by which way you are using your TLB file? I mean are you using relative path to import the TLB file? Sometimes this happens if you have wrong TLB file referenced in your project. If you can check this and let me know. ============= Regards, Jigar Mehta [quoted text, click to view] > Hi > > I unregistered everything and added the assembly to the GAC, still the > problem remains. > > Is there some different situations than class is not really registered > that might cause "Class not registered" error message (for example > some needed module is missing etc.)? > > Jigar Mehta kirjoitti: > >> Hello, >> >> Yes, you can use regasm /u <assembly name> OR regasm /unregister >> <assembly name> for unregistering the assembly. >> >> ============= >> Regards, >> Jigar Mehta >>> Hi >>> >>> With the win 32 (development) machine I can register the C# Com >>> object with command "regasm MyModule.dll /tlb:/my/typelib/path >>> /codebase" without any problem. >>> >>> There has been different dll versions of the same module on the test >>> machine (x64) which might not be unregistered properly.
