Ok I am doing a check to see if a name is in a database or not. Returns true if it is, false if it isn't there..

Is the following code the best practical way to do this or is there a better way and I'm being clueless?

Private Function IsAccount(ByVal strSQL As String) As Boolean
 
        Dim oConn As OleDbConnection = New OleDbConnection(sConn)
        Dim cmd As OleDbCommand = New OleDbCommand(strSQL, oConn)
        Dim r As OleDbDataReader = Nothing
        Dim retValue As Boolean = True
 
        Try
            'Open the connection
            oConn.Open()
 
            'Get the reader
            r = cmd.ExecuteReader
 
            'Check to see if this account name exists
            If (r.Read) Then
                retValue = True
            Else
                retValue = False
            End If
 
        Catch ex As Exception
            retValue = True
        Finally
            If (Not r Is Nothing) Then r.Close()
            oConn.Close()
        End Try
 
        Return retValue
 
    End Function

Any insight, critisizm, or general "You should'nt do it that way" or "Here's a better way" comments are all welcomed...
