Progress Meter

Hello Everyone:

I am trying to use a power meter to track the progress of my program; this will be for my use only and will be removed later. I would also like to display the percentage run in the meter. I already know what the start and end points will be for the meter. What do I need to search for? I have been looking and haven’t been able to find anything that suits my needs yet. I am running VB 2005.

Thanks

Art W.

I'm not sure what you're actually asking for. Are you saying that you want a dial-type progress indicator, like a speedometer in a car? Your first sentence makes it sound like you have external hardware that you want to use to indicate progress, but the second sentence suggests that is not the case.

Hi,

No I want a bar type meter that progresses as the program progresses.

Thanks

I was assuming that you were aware of the ProgressBar control but were not using it for a specific reason, but now I'm not so sure. There's a ProgressBar control in your VS Toolbox. Have you tried that?

Ah, I guess that the requirement to have the percentage displayed in control would preclude the standard ProgressBar. For future reference, using terms like "power meter" is only going to confuse people because you're not measuring any power. All you had to say was you want a control like the ProgressBar but one that can display the percentage on the bar.

I'm quite sure that there are numerous examples of just that around already. If I was looking, I would just search for "custom progressbar .net". Seems the obvious choice to me. That said, it's not too hard to whip up something yourself with a bit of GDI+. Example code to follow.

I dont think you need to go to any trouble. I understand you are doing this only in the development stage and would be removed later. So, put the progressBar control, which is very straight forward and a separate label with the percentage text. It does not need to be really neat if you are not using it in the end product.

You just need to put the ProgressBar control on your form and set the minimum and maximum values and stretch it as you need. then in the program you control the value property. that's it.

I'm sure you could go with GDI+ but I decided to use a Panel and two Labels. I created it in VS 2010 so I've provided code only. If you create a new project and add a Button, a Panel, two Labels and a BackgroundWorker and then the following code, the whole thing should work. This is just one way you could do it. There are various others, including putting this functionality into a UserControl.

Code:

Imports System.Threading

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.Label2.AutoSize = False
        Me.Label2.SetBounds(10, 100, 200, 25)
        Me.Label2.BackColor = SystemColors.ControlDark
        Me.Label2.ForeColor = SystemColors.ControlText
        Me.Label2.TextAlign = ContentAlignment.MiddleCenter
        Me.Label2.BringToFront()

        Me.Label1.AutoSize = False
        Me.Label1.Parent = Me.Panel1
        Me.Label1.SetBounds(0, 0, 200, 25)
        Me.Label1.BackColor = SystemColors.Highlight
        Me.Label1.ForeColor = SystemColors.HighlightText
        Me.Label1.TextAlign = ContentAlignment.MiddleCenter
        Me.Panel1.SetBounds(10, 100, 0, 25)
        Me.Panel1.BringToFront()

        Me.BackgroundWorker1.WorkerReportsProgress = True
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Not Me.BackgroundWorker1.IsBusy Then
            Me.SetProgress(0)
            Me.BackgroundWorker1.RunWorkerAsync()
        End If
    End Sub

    Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
        For count = 0 To 100
            Me.BackgroundWorker1.ReportProgress(count)
            Console.WriteLine("count = " & count)
            Thread.Sleep(500)
        Next
    End Sub

    Private Sub BackgroundWorker1_ProgressChanged(ByVal sender As Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles BackgroundWorker1.ProgressChanged
        Me.SetProgress(e.ProgressPercentage)
    End Sub

    Private Sub SetProgress(ByVal progress As Integer)
        Me.Label1.Text = progress & " %"
        Me.Label2.Text = progress & " %"
        Me.Panel1.Width = progress * 2
    End Sub
End Class

That's a point. I forgot that part. Now I've gone to some trouble. :cry:
