VB.Net 2003 - Not Sure whether CONNECTION is CLOSE

The connection will be closed unless an exception occurs in the lines preceding Connection.Close. In order to ensure that the connection is closed regardless of whether an exception occurs, put Connection.Close in a Finally block:

Public Function GFActionRec(ByVal iSql As String) As Integer

'this routine provides generic function for Insert/Delete/Update to table

Try
With adoCmd
.Connection = New SqlConnection(GFGetDataPath)
.Connection.Open()
.CommandText = iSql
GFActionRec = .ExecuteNonQuery()
End With
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
adoCmd.Connection.Close()
End Try
End Function
