Hi
I am calling a method of a .NET component from both win forms and web
service applications.
Strangly, it is working fine from win forms application, but when i
call the same method (same code with same input values) of that . NET
component from the web service method it is giving the following
exception,
[System.ArgumentException] {"Object type cannot be converted to target
type." }
_remoteStackTraceString "\nServer stack trace: \n at

I don't know how come the same code is working from the win forms
button action.
Can anyone please suggest me on might be the problem. I both cases i am
referencing the .NET dll to the application.
Thanks,
