SQLDMO error in Test Case 31 for Windows Vista

Hi Experts,

I´m trying to certificate my application to Windows Vista.
I´m using SQLDMO in a Visual Basic 6 application, but I´m having trouble in Test Case 31.

In the Test Code below I receive the message:
-2147483645-Automation error One or more arguments are invalid

Private Sub Command1_Click()
    Dim oNameList As Object
    Dim oApplication As Object
   
    Dim n As Integer
   
    On Error GoTo Erro
   
    Screen.MousePointer = vbHourglass
    Set oApplication = CreateObject("SQLDMO.Application")
    Set oNameList = oApplication.ListAvailableSQLServers
    Set oApplication = Nothing
    Combo1.Clear
    For n = 1 To oNameList.Count
        Combo1.AddItem oNameList(n)
    Next n
    Combo1.ListIndex = 0
    Set oNameList = Nothing
    Screen.MousePointer = vbDefault
    Exit Sub
Erro:
    Screen.MousePointer = vbDefault
    MsgBox Err.Number & "-" & Err.Description
    Set oApplication = Nothing
    Set oNameList = Nothing
End Sub

Private Sub Form_Load()
    Combo1.Clear
End Sub

IanWelch,

the code works fine if I don´t use AppVerifier and Windbg.

I´m talking about TC 31. You need to use AppVerifieer and Windbg.

Using your code the error occur on line 1010. Same message.

In my test machine I installed SQL Server 2005 Express edition.

The code worked fine on my Vista machine.

Having said that, there's the possibility that no servers are found in which case the line
Combo1.ListIndex = 0
would result in error.

Can you try the following code and see if you still get error. If so, on what line does the error occur?

Private Sub Command1_Click()
        Dim oNameList As SQLDMO.NameList
        Dim n         As Long

        On Error GoTo Erro

1000    Screen.MousePointer = vbHourglass
1010    Set oNameList = SQLDMO.Application.ListAvailableSQLServers
1020    Combo1.Clear

1030    If oNameList.Count > 0 Then
1040        For n = 1 To oNameList.Count
1050            Combo1.AddItem oNameList(n)
1060        Next n
        End If

1070    Set oNameList = Nothing

1080    If Combo1.ListCount > 0 Then
1090        Combo1.ListIndex = 0
        End If

1100    Screen.MousePointer = vbDefault

        Exit Sub

Erro:
1110    Screen.MousePointer = vbDefault
1120    MsgBox Err.Number & "-" & Err.Description & vbCrLf & "at line " & Erl
1130    Set oNameList = Nothing
End Sub

Private Sub Form_Load()
    Combo1.Clear
End Sub
