Progress Bar Running

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?

Look up worker threads, and use System.threading.thread ...

sample code i use to process reciepts

Code:

---

                    If MsgBox("Print receipt for this transaction?", MsgBoxStyle.YesNo Or MsgBoxStyle.DefaultButton1) = MsgBoxResult.Yes Then
                        Dim WT1 As New System.Threading.Thread(AddressOf PrintReceipt)
                        WT1.Start()
                    End If




        Private Sub PrintReceipt()
            Dim TmpPrinter As New Printers.PrinterModule("ID1")
            Dim nr_of_copies As Integer
            For nr_of_copies = 1 To Copies.KeyVal 'get nr. of copies as setup in File/Properties
                TmpPrinter.Print()
            Next
        End Sub

---

In this I spawn a worker thread to take care of all the printing, and can now continue processing the transaction...

I tried your code, but how can I embedded my progress bar codes into the thread so that the bar will running?
