Concurrency Problem

[Marcel Groffen]

Hello to all,

I have a problem between 2 programs I have running.

We have got an old databridge for our clients to upload data to our
central database. This one is written in C++ (not by me).
We now have a new Databridge developped, which is written in VB.NET.
Functionally they are the same, but technically there are differences.

I think we have got a concurrency problem, because when the new
Databridge (VB.Net) is running (several instances), the old databridge
will not run.

The error given by the old databridge, is that it cannot connect to
the database, while it can when NOT using the new databridge.

Some technical details:
Old Databridge:
- C++;
- using port 8041 (this one has a direct connection with the client);
New Databridge:
- VB.Net

All is running on a Win2K SBS SP3 with SQL Server 2000.

It is difficult for me to explain, so when more information is needed,
please ask me!!

Thanks to everyone in advance.

Kind Regards,

Marcel Groffen

Hi Marcel,

Ask this question also in the newsgroup

microsoft.public.dotnet.framework.adonet

There you have probably a better change to get a fast answer on this
question.

I can give you a simple advice, I would make the new VB.databridge with a
different name and check what happen when those two work at the same time.

If not the problem is in the VB part if they do the problem is in the C++
part.

I hope this helps?
