I f tried many times but failed. Plz help me, I'm newbie in vb.net n correct if I'm wrong.

Below is the code.

Private Sub txtMRN_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtMRN.KeyPress

        Dim cnSQL As SqlConnection
        Dim cmSQL As SqlCommand
        Dim drSQL As SqlDataReader
        Dim strSQL As String

        Try

            ' Build Select statement to query product information from the products table 
            strSQL = "SELECT mrn FROM tbl_patient_registration WHERE mrn=" & Val(Trim(txtMRN.Text))

            cnSQL = New SqlConnection(ConnectionString)
            cnSQL.Open()

            cmSQL = New SqlCommand(strSQL, cnSQL)
            drSQL = cmSQL.ExecuteReader()

            If drSQL.Read() Then
                ' Populate form with the data
                txtMRN.Text = drSQL.Item("mrn").ToString
                lblName.Text = drSQL.Item("p_name").ToString()
                lblSex.Text = drSQL.Item("p_sex").ToString()
            End If

            ' Close and Clean up objects
            drSQL.Close()
            cnSQL.Close()
            cmSQL.Dispose()
            cnSQL.Dispose()

        Catch e1 As SqlException
            MsgBox(e1.Message, MsgBoxStyle.Critical, "SQL Error")

        Catch e2 As Exception
            MsgBox(e2.Message, MsgBoxStyle.Critical, "General Error")
        End Try

    End Sub
