Need help for COM running from Web application, but not form .EXE application

[JeffQ888]

Hi,


Can anybody help me to figure out my issue I am currently facing. The
issuse is we are building a .NET application on top of a third party
software. Since the software is based on old Microsoft technology ( I
mean COM), we are using .NET TlbImp utility to wrapper
COM dlls, then we can use them in a C# application. Anyway, for some
reason, those new .NET dlls ( I meam after warpping) can only work
correctly from a Web application. If calling them from a .NET exe
application (Windows Form app or Window Service app), those dlls will
not work. The error message is "mscorlib Exception has been thrown by
the target
of an invocation.". I am gussing those old COMs relying on Web
environment, but just can't fingure out how to solve it. It will
appreciated if anybody can give me some help.



Thanks,




Jeff

The com objects are installed on the local machine (win forms) as well
as the iis box right?

Can you create a reference directly to the com object in your win form?
