Marshal.GetActiveObject fails with InventorServer Object. Help!

[KKizildemir]

Hi,

I'am trying to write some code on VS .NET Framework 4.6.1 and to generate a .dll file for my Inventor model that works on C360. So I can not use 'Inventor.Application' object. That's OK.

When I use 'Inventor.InventorServer' object, I can't set that object reference to the intance of my object. I think 'Marshal.GetActiveObject' does not work in this case. So what is the solution?

This is the error message: Object reference not set to an instance of an object.

This is related part of my code:

        Dim oThisServer As Inventor.InventorServer = Nothing
        Try
            oThisServer = Marshal.GetActiveObject("Inventor.InventorServer")
        Catch ex As Exception
            Exit Sub
        End Try

Thanks!

Is inventor server already running.
Otherwise use createobject.....

Hi Arthur,

Sorry, I didn't get you. Maybe you would like to do your solution clearer.

Thanks anyway.

I think that Inventor Server can only be used in the context of a job. 

GetActiveObject() can not get an instance, it will always returns null.

Inventor Server is started from C:\Program Files\Autodesk\Vault Client 20xx\Explorer\Inventor Server\Bin\VaultInventorServer.exe and then there is a specific process to connect to the running instance which can not be used by an external developer (only Autodesk can use this).

That is correct.

You can only use it with a Vault JobProcessor Job!
