I trying to write a COM object in VFP that will expose its database functions to other languages like VB and VC. I seem to be doing well so far except when it comes to passing optional paramters. In VFP I do not receive an error if I use...

MyData.Close()

... this should close all open tables. But when I try to do the same in VB I get an error "Agrument not optional...". This is how I used the object in VB.

Option Explicit
Dim MyData as New VFPData

Sub Form_Load()
MyData.Open "D:\MyProgs\MyTable.DBF"
...
End Sub

Sub Form_UnLoad()
MyData.Close && This is where the error happens since I did not
pass an Alias name of an open table.
...
End Sub

Please e-mail me if you have a answer.

Thanx! in adavance.
