Modeless Form timer does not tick until after processing is complete

[david_rock]

Hello,

I have a modeless form that I have added a timer control.

On OK button click I have

Timer1.Interval = 1000
Timer1.Start()

And have the following:

    Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
            If uxProgressBar.Value + 1 < uxProgressBar.Maximum Then
                uxProgressBar.Value = uxProgressBar.Value + 1
            Else
                Timer1.Stop()
            End If
    End Sub

However it seems that my progress bar does not move until after the processing is complete.

Any ideas?

Kind Regards

David

Dear David,

To do you have to use Invoke method. Timer tick is not working.

Steps:

Step 1: Make function asyn.

Step 2: Invoke progress bar method.

Example:

private async void funcationName()

{

  //  Assigning maximum value for progress bar

  progressBar_Part.Invoke(new System.Action(() => this.progressBar_Part.Maximum = Count));

// Show  status on lable;

  this.label_progress_part.Invoke(new System.Action(() => this.label_progress_part.Text = "Processing Elements : " + (i + 1) + "/" + count));
  this.Invoke(new System.Action(() => this.Refresh()));

// Increasing Progress bar
await Task.Run(new System.Action(() => { this.progressBar_Part.Invoke(new System.Action(() => this.progressBar_Part.Value = i + 1)); }));
await Task.Run(new System.Action(() => { this.Invoke(new System.Action(() => this.Refresh())); }));

}

Thank you for the reply.

I am able to move the progressbar along. The main think I am after is perhaps a background worker example of a timer as the forms timer is not ticking.

I need to use the timer so that the progress bar continues to move during a long process, such as synchronizing and printing.

Otherwise the progress bar appears jerky.

Kind Regards

Dear David,

I have implemented various timers running in a modeless context in a separate thread, e.g. to raise an external Revit event at certain intervals, e.g. here:
