*** Ruud - is this a COM bug or "lack-of-feature" ? *** (Shawn)

I am trying to use Kixtart to script Microsoft Virtual Server 2005 R2 but it simply doesn't work with Kixtart at all!

The following VBS code works just fine:

 Code:
Set objVS = CreateObject("VirtualServer.Application")
Set vm = objVS.FindVirtualMachine("Server1")
Wscript.Echo "Name=" & vm.Name


But the Kixtart version:

 Code:
$objVS = CreateObject("VirtualServer.Application")
$vm = $objVS.FindVirtualMachine("Server1")
? "Name=" + $vm.Name


Always returns -2147352567 which translates into 80020009 which as far as I can see is some sort of "Exception occurred" or if I take the 9 and type NET HELPMSG on it says "The storage control block address is invalid".

The CreateObject itself doesn't return an error but as soon as I try to do something with it @ERROR is set to the value mentioned above.

I dont have this object, but try this:

Can you try some debugging lines and report back ?

$objVS = CreateObject("VirtualServer.Application")

?"FindVM=" + VarTypeName($objVS.FindVirtualMachine)

?"Server1=" + VarTypeName($objVS.FindVirtualMachine("Server1"))

? "Name=" + $vm.Name

Hi Shawn!

The result of the debug code is:

FindVM=Empty
Server1=Empty

Whats the error code after the call to FindVirtualServer ? Might want to add in the WrapAtEol to show those long COM messages.

$= SetOption("WrapAtEol", "On")

$vm = $objVS.FindVirtualMachine("Server1")

? "ERROR @ERROR - @SERROR"

Well that's the strangest thing. Should work - it appears like VBS COM is "doing something" that Kixtart is not. Think I may have found out what the difference is - here's a quote from MSDN:

 Quote:

Connecting to the Virtual Server COM Object

The Virtual Server programming interface is a standard COM object. Before any of the interfaces are accessed, the COM layer is initialized, the default security access level is set, and a pointer to the main IVMVirtualServer object is obtained. All other Virtual Server objects are accessed through this primary interface.

The Virtual Server COM interfaces can only be accessed if the COM Security level is set to Impersonation level or higher. By default, COM uses the Identification security level if no level is explicitly specified. To set the COM security level, the user's program should make a call to CoInitializeSecurity immediately after the initial CoInitializeEx call and before any of the Virtual Server's interfaces are accessed.


Its the second paragraph that may apply. Not sure if Ruud (developer) is calling the CoInitializeSecurity function on created com objects or not.

I'm going to move this thread to BETA and hopefully Ruud can respond.

Thanks for this report. Haven't seen this problem before, I'll dive into it and let you know what I find. Cheers, Ruud
