Problem with COM dispatcher in Analysis Automation

[adlevo1]

Dear all,

I am trying to set up an Analysis Automation Procedure in SystemLink 19.6 TDM Server.

I have created the VBS analysis script in DIAdem 19 SP 1, which involves the creation of an MD5 checksum (code snippet attached). It runs fine in DIAdem, but testing it in SystemLink's Analysis Automation Procedure Library environment, it breaks at the line

Set MFoMD5 = CreateObject("System.Security.Cryptography.MD5CryptoServiceProvider")

with the error "Exception from HRESULT: 0x80020101", which points to the COM interface.

I have found some examples for wrapper code in VB and .NET, which involves customizing the compiling, but what can be done here?

Thanx a lot in advance,
Volker

Hello Volker,

I have created a very simple test vbs script where only the create object is called (see attachment). I was able to reproduce the error.

The components used in create object are included in .NET 3.5, which was not installed on the machine where SystemLink TDM Server was running.

You can install the missing components by directly downloading .NET Framework 3.5 from Microsoft or by using the "Turn Windows features on or off".

Note: Not all COM Components are thread safe and when executing a analysis procedure in parallel mode it could happen that some of the CreateObjects will fail.

Please let me know if this fixes your problem.

Kind regards,

Alin

Hi, Alin!

Just to let you know: I'm still waiting for my IT to install .NET 3.5. Big company bureaucracy...

Thanx for the advice already now,
Volker

Hi, Alin!

As you could guess, since I accepted your solution: It works.
Thanx a lot!
