Hi
Unfortunately you cannot deal with C# so much. The only one way to do this
is when your c# lib is COM accessible. If so, this white paper can help if
not you should modify c# lib.

I am sorry.
Of course you can create a web service in C# and then access your functions
from Team Developer.

Okay,
thank you for the answer, the white paper was very helpful. I build the dll
file like the sample in the white paper. Then i want to load the dll file in
the Active X Explorer. But I get an error message. Unaable to load type
library "C:\*******\test.dll".
Where is the mistake?
Sorry, but my english is not so good.

Do you have this type library in this folder?
Do you have VS project on the same machine with GTD?
Did you try register this assembly with regasm.exe? (If prev answer is 'NO')
(And you should remember to do this when you will deploy your app)

hi,
okay,... at first I develop in VS.NET and Team Developer on the same
machine.
I created a type library file with tlbexp.exe.
Then I loaded the dll-File in Team Developer.
But now when I call the function from the dll File i don't get a return
value.
In the c# function i write 'return "Hello";'.
I call the function like the description in the white paper.
What's wrong.
Do you have any other sample code for me. I don't see the mistake.

so long...

Hi
Since you have not attached you c# project I can't see any mistake either.
I can only guess than your c# project is not configured to create com
objects (Are you using express edition?)
Or you have made mistake doing translation from vb to c#.
It could be a way you handle interfaces.
It should be done like this.
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
public interface IMyInterface

Ok
So
C# is "ok" but you forgot declare namespace and in gupta you are trying to
create object "ManageClass.NETClass"
Where "ManageClass" is really namespace name in c#, So you have two options
here 1. Add namespace to your c# project what is in my opinion the best
solution; or 2. Remove this namespace and leave only "NETClass" in you Gupta
code.
The second solution works fine but is good only for tests and small
projects.

Did the GUID of the assembly change?

Maybe it needs to be re-registered (see regasm.exe)

I don't see the AssemblyInfo.cs file in your project. It should contain
this line:

[assembly: ComVisible(true)]

Also in the project properties, on the Build tab, make sure Register for COM
interop is checked.
