Python COM Variant problem

[Annie]

I am trying to call a COM object which expects a variant datatype to
be passed in to the COM API object. However, I get "<COMObject
<unknown>>" and the program fails.

Below is my code in Python, and the same code in VB which is working
fine...

I guess this is a variant problem with python? How can I make this
work? Would appreciate if someone can guide me as I am a python
newbie...

Thanks very much...

##In Python
def setAddOnValue(oBusObj
oAddOns = oBusObj.AddOns
print oAddOns #returns "<COMObject <unknown>>"
print oAddOns.Count #return 3
for x in range(1, oAddOns.Count):
oAddOn = oAddOns.Item(x) #expects variant datatype for the x
variable



##In VB
Public Function setAddOnValue(oBusObj As Variant, strAddOnLabel As
String, strPropLabel As String, oVal As Variant) As Boolean
Dim x, y
Dim oAddOns As CAddOns
Dim oAddOn As CAddOn
Dim oAddOnValues As CAddOnValues
Dim oAddOnValue As CAddOnValue

setAddOnValue = False
Set oAddOns = oBusObj.AddOns

For x = 1 To oAddOns.Count
Set oAddOn = oAddOns.Item(x)
If oAddOn.AddOnName = strAddOnLabel Then
Set oAddOnValues = oAddOn.AddOnValues
For y = 1 To oAddOnValues.Count
Set oAddOnValue = oAddOnValues.Item(y)
If oAddOnValue.PropertyLabel = strPropLabel Then
setAddOnValue = True
Set oAddOnValue.Data = oVal
Exit For
End If
Next y
End If
If setAddOnValue = True Then
Exit For
End If
Next x
End Function

Try running makepy on the typelib that contains the objects.
Also, the actual error msg that if fails with would be helpful.

Normally if you've run makepy, the support should be invoked automatically
when you create an instance. What do you get back when you use
win32com.client.gencache.EnsureDispatch ?
