I have the following code:


Code:
Private Sub btnConfirm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConfirm.Click
        Try
            CheckSignature()

            If flashBMSign = False And flashCustSign = False And flashConsSign = False Then
                If FnProcessApproval() Then
                    If chkCOOApproval.Checked = True And strRole <> "COO" Then
                        MsgBox("Successfully pass the approval to COO!")
                    Else
                        MsgBox("Successfully Confirm Approval.")
                    End If
                End If
            End If
        Catch ex As Exception
            MsgBox(ex.Message, MsgBoxStyle.Information, Me.Text)
        End Try
    End Sub

May I know how can I put a progress bar to make it keep running when the function FnProcessApproval() is running and stop when the messagebox is display?
