Running transcript files in Inventor 2011

[cadsupport]

I'm still struggling with transcript files.

My aim is to benchmark client performance in opening files from vault in Inventor.

I have created a transcript file to download, checkout, update and checkin files from within Inventor 2011. 

The transcript file works perfect, but a full automation would require an automated execution of this script.

I have used a bit of VBA code:

Sub AutoStart()

Dim Inventor As Application
Dim ActiveDocument As Inventor.Document
Dim oControlDef As ControlDefinition

ThisApplication.SilentOperation = True
Dim ComMan As CommandManager
Set ComMan = ThisApplication.CommandManager

Call ComMan.PostPrivateEvent(kFileNameEvent, "c:\temp\transdir\testfall-1.tf")
Set oCtrlDef = ComMan.ControlDefinitions.Item("AppReplayTranscriptCmd")
oCtrlDef.Execute

ThisApplication.SilentOperation = False

End Sub

Although I have added the PostPrivateEvent, the dialog will always pop-up, that asks for the transcript file name.

Can anyone help?

Oh, and it doesn't have to be VBA. I'm more familiar with C#. So if there's a function in C# for calling a transcript file, that would do the job.
