Show message while progressbar is processing

[kbalor]

So I want to make a Text while ProgressBar is processing. A text will show below the progressbar like. "Please wait...." then a second text if it hits the middle of the bar it will say "Verifying..." and the last text if it hits the last bar or the end will be "Complete!" something like this..

This are my codes

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        ProgressBar1.Increment(1)
        If ProgressBar1.Value = ProgressBar1.Maximum Then
            Button2.Enabled = True
        End If
        Label2.Text = ProgressBar1.Value & (" %")
    End Sub

    Private Sub ProgressBar1_Click(sender As Object, e As EventArgs) Handles ProgressBar1.Click

    End Sub

Thanks!

Firstly, ProgressBars don't process anything. They just sit there showing a fraction in a fancy UI. You do the processing in code and then you set the fraction being displayed in the ProgressBar to indicate where that code is up to.

As for the question, I'm not sure what the problem is. If you want to display a message in a Label then go ahead. You obviously know how to display text in a Label and you obviously know how to use an If statement to determine the state of the ProgressBar so what exactly is the issue?

I have the same problem...

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        ProgressBar1.Increment(3)
        If ProgressBar1.Value = ProgressBar1.Maximum Then
            Timer1.Stop()

        End If

        If ProgressBar1.Value & ("1") Then
            Label1.Text = "Status: Start"
        End If

        If ProgressBar1.Value & ("50") Then
            Label1.Text = "Status: Bla"
        End If

        If ProgressBar1.Value & ("100") Then
            Label1.Text = "Status: Finished"
        End If
    End Sub

With this code the Label only shows :" Status: Finished"

How would be the correct syntax?

I think the problem the both of you are having is this:

Everything is running on the same thread, which means that the UI is not updating while the progress bar is working.

Try running the progress bar as a background worker

I dont know much on the topic but hopefully someone else chimes in

I am pretty sure, that there is a more easy way than that, but thanks anyway.

Propably there is someone else who could help me/us with that problem?

Well, you'd run the process as the background worker and keep the progress bar on the UI actually. I doubt that either case demands this approach but even if it does the programming of the label will be the same and it's difficult to see why there should be any problems with it.

In cocobrico's case it's this ...

If ProgressBar1.Value & ("1") Then

... which is the problem. Makes no sense. It really is very simple ...

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        ProgressBar1.Increment(2)
        Select Case ProgressBar1.Value
            Case Is < 20
                Label1.Text = "Give me a chance, I've only just started!"
            Case 20 To 39
                Label1.Text = "Now we're getting somewhere!"
            Case 40 To 70
                Label1.Text = "Better finish that coffee. Won't be long now."
            Case 71 To 98
                Label1.Text = "Nearly there."
            Case Else
                Label1.Text = "All done!"
                Timer1.Stop()
        End Select
    End Sub

Having said that I'm not a fan of timer based progress bars not least because they are inherently inaccurate.

Thank you!! :-) It's working like charm!

ProgressBar1.Value & ("1") means what? The ampersand means: Put two strings together, so if the value of the ProgressBar happens to be 25 then 25 & "1" = "251" so what does the If statement:

If "251" Then

means, well not much... Since you have Option Strict set to Off it means: "251" is not false so it must be true...
