IPC between VB6 COM control and C# application

[Guest]

I'd like to pass a simple string from a VB6 COM (dll) to a c# application
(we're new in c#). I need to do this while the c# program is running (IPC,
not in the program argument). Can anyone help guide me to the most
clean/simple technique?

Hi,

Tips: Shared Memory, TCP/IP, NamedPipes ...

...or ..
I wroted IPC Library for .NET.. you can see it on
http://www.habjansoftware.com/ipc_library.aspx .
I can modify it to be COM accessible if you are interested, so it can be
used between VB6 and C#.

That means you have a method in your COM dll that returns a string, right.
What you could do is simply create a interop assembly using tlbimp.exe and
add a reference to this assembly (or set a reference to your COM dll in VS)
and call the method from C#.
Check MSDN for details on COM Interop in .NET
