SOTAMAS90 and ACCESS DAO

[tmcelroy]

I have created an Access 2000 form connecting to MAS90 tables. I created ODBC User and System DSN configurations named SOTAMAS90_VB. On my Open Form code I attempted to open the ODBC connection to avoid the Sign On window. The code is as follows:

Dim DAOws As DAO.Workspace
Dim DAODB As DAO.Database
Dim DAOrs As DAO.Recordset
Set DAOws = CreateWorkspace("UDALinkWorkspace", "", "", dbUseODBC)
Set DAODB = Workspaces(0).OpenDatabase("", False, False, "ODBC;DSN=SOTAMAS90_VB;UID=PSI|ABC;PWD=KISS;&quot
(note: PSI = user, ABC = Company)
I am able to open and read the linked tables without encountering the sign on window. However, I have combo boxes that reference the tables. Whenever these combo boxes are referenced, I encounter the sign on window. (Sign On asks for Company, User Name and Password)
Example of referencing combo box below:

For Idx = 0 To cboCustomer.ListCount - 1
MsgBox (" reading cboCustomer - Idx= " & Idx)

Next Idx

Why can I open and read tables without the sign on window, but any combo box reference prompts the sign on?
Thanks!
