.NET Remoting and LabVIEW as a server

[sangjin]

Hi

I'm trying to connect labview and c# application via .NET Remoting.

First I'll explain briefly the software structure.

There is an assembly which manages all about .NET Remoting.

By using this assembly, commnications among applications can be easily perfomed.

The application can be implemented by C# or labview. 

In labview app, it has nothing with .NET Remoting. Instead, it just instantiates

some class in the assembly which take care all about .NET Remoting.

When the labview app. communicates with other C# app. via .NET Remoting,

the problem is that when the c# app as a client tries to access to objects in labview app.

which is set up as a server, an error is ouccured like this :

"unable to find an assembly which includes the types which is set up as  .NET Remtoing server"

But, when the labview app. conducts as a client, communication works well.

This is, the access to .NET Remoting servers hosted by labview app. from other c# app. is blocked.

Any replies would be welcome.

Thank you in advance.

first check the firewall....

When communicating between C# app., everything is ok.

I think this means firewall doesn't matter.

However if labview has its own firewall function, it could be the cause.

I solved this problem by copying all necessary assemblies to the folder where the labview.exe file exists.
