Thanks shouvik! I think only containing interface information is not enough. I think it should also contain the CLSID (implementation class guid of the interface) information, right? Or else, in client program, how could we know and pass both the IID and CLSID information to QueryInterface? regards, George

Thanks ThatsAlok,

If I have a C++ client and a C# COM component. Without a tlb file, how could the C++ client utilizing the C# COM component? I do not think it could be achieved by using header file, since C# does not have any header files. For managed C++ client, we could import DLL directly, but for unmanaged C++ client, how could we utilize C# COM interfaces/classes without a tlb? regards, George

since c# com component deploy managed stuff, i believe might be you are not able to use it in c++ native.. but by the way... what C# dll is COM Server Exe or DLL

Might be they have some wrap over class informations written within the COM component. I actually am more like a novice when it comes to COM. Please forgive me :-O

Thanks ThatsAlok, I have tested that we could invoke C# (COM) function from C++ unmanaged code. regards, George

I don't have much Experience in InterOpr!, but just want know what C~ compiler is producing, is it dll or exe

Because the C# COM component implements
IDispatchamong other interfaces. With this one you have an automatized component, and you don't need to know the name of the method invoked, only their number (1, 2, 3, etc) which can be found in the extra information of the component, defined with IDL language.A polar bear is a bear whose coordinates has been changed in terms of sine and cosine.

Hi ThatsAlok, I have found there is no .tlh and .tli generated in C# COM server project. Do you know how to make then generated? regards, George

look if this help How to call a COM C# component from VC++?[^].. and by the way the original name is Alok :)
