rs.Open "SELECT * FROM [tbladmin] WHERE [username]= '" & txtUsername.Text & "'", con, adOpenStatic, adLockOptimistic

        If rs.RecordCount <> 0 Then
            If rs![Password] = txtPassword.Text Then
                If rs![user_type] = "Principal" Then

                    MsgBox "The Principal has login", vbOKOnly + vbInformation, "LOGIN"

                        frmMain.Transaction.Visible = True

From the help system, "ADO Error Codes":
*adErrInvalidConnection 3709
The application requested an operation on an object with a reference to a closed or invalid Connection object. *

So that tells me you have either a) not properly opened your connection object (but we can't see what's in the "OpenCon" subroutine) or b) not properly defined and/or instantiated your connection object.

It is entirely possible that the problem is in your OpenCon subroutine. Double check that you aren't running into a variable scope issue.

Hope that helps! Good luck!
