I’ll need to use the PowerShell parser to find each reference to Write-Progress just inside of the function itself.
However, it gets a little hairy at this point. Once I figure this out, I can then do some arithmetic to get the actual percentage values. To do this, I first need to find out how many Write-Progress calls I have.

To do this, I’ll first need to figure out a way to prevent having to hard code the PercentComplete value in each Write-Progress call. We need to refactor this code to come up with a more dynamic way to specify the PercentComplete parameter and remove as much code duplication as possible. If you want to use a progress bar, you might consider having your job script output the percentage of progress.

Also, I’m not following the DRY principle here by repeating the same string Write-Progress -Activity 'Title' -Status 'Doing something' four different times. Displaying Progress with the Job Tracker: If you want to display partial data or the Job’s progress, you should use the Receive-Job cmdlet during the update script block. Notice that I had to statically assign the values 0,25,50 and 75? We never want to statically code anything unless necessary. Write-Progress -Activity 'Title' -Status 'Doing something 4' -PercentComplete 75Īt first glance, you might not notice a problem here but think about how this is maintained. Write-Progress -Activity 'Title' -Status 'Doing something 3' -PercentComplete 50 The timer checks the status of a job that is created when the button is pressed.
The Start-Sleep cmdlet at the end of each step gives a slight delay allowing the progress bar to display the script step text. The progress bar PerformStep () method visually increments the bar.
If you look at the control set it inserts a button and a timer. The progress bar TextOverlay property displays the step text. It will stop every time at that point and only frees up again when the job is completely done. The fact that your are doing a loop to check every time the status of the job is why the interface freezes. More info on the SAPIEN page PowerShell Studio: Creating responsive forms. Version 3.0.3 of PowerShell Studio has a Control Set called Button Start Job. So it doesnt freeze the interface and even updates a progress bar if you will. Write-Progress -Activity 'Title' -Status 'Doing something 2' -PercentComplete 25 Now that we covered the caveats, we can now begin to modify our forms so that it can handle jobs.
