DLL returns a variant data type - how to convert and use in VB .NET

[darrenbenn]

I need to convert this code to VB .NET (2003).

Dim FaxMsg As IFaxMessage

Set FaxMsg = gFC.NewMessage

Dim Recip As Variant
' add a recipient to the fax recipients collection
Set Recip = FaxMsg.Recipients.Add(0)
Recip.Name = sWho
Recip.Company = sCompany
Recip.FaxNumber = sPhone

The problem I am having is that variant type does not exist in .NET and
FaxMsg.Recipients.Add(0) returns a variant type. I have Option Strict
and Option Explicit set to On. The upgrade utility converts the Variant
to type Object which is no good as I can't access Name, Company and
FaxNumber properties of Recip.

Thanks in advance

You can cast the object into the correct type using the CType method. So if
the type you want is a Recipient you would do it like so

dim temp as object

temp = FaxMsg.Recipients.Add(0)

dim Recip as Recipient = CType(temp, Recipient)
