VMware Server 2.0, VIX API 1.2, MS VS2005 Visual Basic ==> DISP_E_TYPEMISMATCH

[rkt]

Hi!

I tried to run that code:

-

---

Private Sub Connect(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Connect.Click

Dim libr

Dim host

Dim vm

Dim err

Dim results

Dim job

libr = CreateObject("VixCOM.VixLib")

job = libr.Connect(VixCOM.Constants.VIX_API_VERSION, VixCOM.Constants.VIX_SERVICEPROVIDER_VMWARE_VI_SERVER, "https://localhost:8333/sdk", 0, "user", "pw", 0, Nothing, Nothing)

' results needs to be initialized before it's used, even if it's just going to be overwritten.

results = Nothing

err = job.Wait((VixCOM.Constants.VIX_PROPERTY_JOB_RESULT_HANDLE), results)

If libr.ErrorIndicatesFailure(err) Then

' Handle the error...

End If

host = results(0)

job = host.OpenVM("C:\VMs\winxppro\winxppro.vmx", Nothing)

err = job.Wait((VixCOM.Constants.VIX_PROPERTY_JOB_RESULT_HANDLE), results)

If libr.ErrorIndicatesFailure(err) Then

' Handle the error...

End If

vm = results(0)

job = vm.PowerOn(VixCOM.Constants.VIX_VMPOWEROP_LAUNCH_GUI, Nothing, Nothing)

err = job.WaitWithoutResults()

If libr.ErrorIndicatesFailure(err) Then

' Handle the error...

End If

End Sub

Like you can see, I modified an example of the VIX reference guide. For running it, I added a reference to the VixCOM 1.0 Type Library (VixCOM.dll).

My problem is that I get always this error in the line of "libr.Connect(...)":

"An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in Microsoft.VisualBasic.dll

Additional information: Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))"

Is anybody able to help me? Thanks!

The sample code given is for VBScript, which is a little different VB.NET, unfortunately.

You'll need to change to code to something like this:

Private Sub Connect(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Connect.Click
Dim libr As VixCOM.VixLib
Dim host As VixCOM.IHost
Dim job As VixCOM.IJob
Dim vm As VixCOM.IVM
Dim results = Nothing
Dim err

libr = New VixCOM.VixLib()
job = libr.Connect(VixCOM.Constants.VIX_API_VERSION, VixCOM.Constants.VIX_SERVICEPROVIDER_VMWARE_VI_SERVER, "https://localhost:8333/sdk", 0, "user", "pw", 0, Nothing, Nothing)
host = Nothing
Dim propertyIDs() As Integer = {VixCOM.Constants.VIX_PROPERTY_JOB_RESULT_HANDLE}
Dim err = job.Wait(propertyIDs, results)
If libr.ErrorIndicatesFailure(err) Then
   ' Handle the error...
End If
host = results(0)


job = host.OpenVM("C:\vms\winxppro\winxppro.vmx", Nothing)
err = job.Wait(propertyIDs, results)
If libr.ErrorIndicatesFailure(err) Then
   ' Handle the error...
End If
vm = results(0)

job = vm.PowerOn(VixCOM.Constants.VIX_VMPOWEROP_LAUNCH_GUI, Nothing, Nothing)
err = job.WaitWithoutResults()
If libr.ErrorIndicatesFailure(err) Then
   ' Handle the error...
End If
End Sub

[esloof]

vm = results(0)

Results is error:

Unable to cast COM object of type 'System.__ComObject' to interface type 'VixCOM.IVM'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{11E879B1-7969-4654-BE4B-3F05679F742E}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Update: I fixed it, there was a typo in my VMX path

Cool huh
