CLSID not found

[Mannie]

Hello everyone!

I want to call a method written in C# from a C++ level.

To do this I create a C# class, I wrap it with [ComVisible(true)] atribute, rightclick on a project , I click "register for COM interop" and rebuild the whole solution (just a standard procedure recommended in this situation)

Then I start a new project in C++ and I want to call my COM object using a construction : "HRESULT hr = CoCreateInstance(CLSID_... " - but, by using an intellicense, I can't find my class (created in c#).

Any idea why my c# COM object didn't received an CLSID number after being build in .NET?

or maby my problem has anothers bases?

Have you registered the C# Com DLL with windows?
(using the regsvr32 command line tool is the easiest way I've found)

If it has been registered, have you given your C++ project permissions to use it?

When I use VS 2005 application isn't it so that it does the whole job for me?? (and I don't have to use regsvr32)? - or maybe regsvr32 does something more ?

What kind of permissions in C++ project do I have to give? Could you explain me this, or perhaps send me an useful URL with explanation,please?

King regards,

Well the RegSvr32 registers your DLL into the Windows Registry. This is how your other applications will be able to look it up and use it.

To register you DLL in windows

• Pick a folder to install the DLL into (your system32 folder is where all your system DLLs are installed into).
• Move your DLL there.
• Open a Command Line window.
• Go to the folder where your DLL is installed.
• Type: regsvr32 NameOfTheDLL.dll

I'd try registering the DLL and re-referencing it in your project before we get into any permissions stuff.
