The TWBSLicenseClient project don't work. There is always an execption thrown:

'System.Reflection.TargetInvocationException' occurred in mscorlib.dll

1. The service on server is running

2. the corba brige is registered as server

3. the Twbslicenseclient don't work on client side and not on server side

    Hi Markus,

    I suggest that you "catch" the exception - and check the message that comes with it.

    It didn't work for me as well - and the reason was that the port (which is hard-coded in the sample code) wasn't open on my machine; I tried another one - and that worked fine...

    • Hi Markus,

      Just to clarify that first:

      Anything you get here on SDN doesn't fall into the scope of the formal / regular support - unless stated otherwise.

      Especially code samples uploaded by externals...

      Anyway - and sorry that I didn't have the time / missed to follow up with your problem...

      ...I still wonder what you did (or not) to isolate the problem?

      - I understand that you installed the Com2Corba license bridge and the .NET service on the same system where the B1 license service is installed???

      - Did you check (e.g. debug on <b>both</b> sides) whether the connection to the .NET service is established successfully?

      - If not there must be sth "wrong" with your .NET installation - or the network configuration / ports ("beginners idea": maybe the port is used by "sth else"?)?!

      - I am not having any issue with the sample (after changing the port number (of course in the service + the client) to a port which I knew it would work on my system (I think 4334).

      - BTW: Did you use the installer from SDN to install the bridge?

      Sorry, but I think there's actually not much that can be "wrong "in the bridge or the .NET service sample; I tend to suggest that you check the situation on another system.
