Hi, and Thank's for your help.
I will try to explain me.
We have a Windows Application solution (MyApp from now) with many class
libraries and one of them libraries reference to an external dll (PBdll)
(developed on PowerBuilder) running this application as a Local application
works fine, we also have a Windows Service App with all the same libraries
(including the one who use PBDll).
Finally in our config file for MyApp we have an option to decide if app will
be Local or Remoting, if remoting the application creates objects through
tcp/http channel)
Everything works fine here but the methods on PBdll class (not the object
itself, It's create without error I guess)
I don't know if is more clear for you now...
Which code do you think could help you to understand more??
Anyway properties for the PBdll reference:
Copy Local true
Culture 0
Description A description
Identity {98989898...}\1.0\0\tlbimp
Path C:\VSS\Work\Source\Varsling\obj\Interop.net_fravsjekk.dll
Runtime Version
Strong Name true
Type ActiveX
Version 1.0
