The TypeValdiationCompleted passes a parameter variable. This event is also fired when the ValdiateText method is called. Use this event in order to react to when a type validation fails or succeeds. $main_(($Label, $StartButton, $EndButton)) This event occurs when MaskedTextBox has finished parsing the current value using the ValidatingType property. $EndButton.Location = New-Object (350, 75) $StartButton.Location = New-Object (350, 75) $procFont = New-Object ("Verdana", 20, (::Bold))

$main_form.Text = 'Subtitle Software Suite'

If ($result -eq ::OK) until ($job.State -eq "Completed") $EndButton.Location = New-Object (350,75) Take a look at this example: PowerShell command ::New (queryString, connection) () command. $StartButton.Location = New-Object (350,75) Sometimes you dont need to handle an error but still need some code to execute if an exception happens or not. $Label.Text = "Audio extraction can take a long time" $main_form.Text ='Subtitle Software Suite' $ProgressBar.Location = New-Object (10,35) NB: I found I had to include the ProgressBar within the function as adding it via AddRange, and then setting it to "Visible" within function meant it didn't show at all Add-Type -AssemblyName PresentationFramework > Calls dialogues (within function) to locate a file / location to save / Program runs silently for 15 - 30 seconds whilst showing marquee progressbar (or animation) but that left me even more confused!Ĭhange label to "Processing" / remove start button

Everything I'm finding is how to disable a button and not individual textboxes or comboboxs. I'm stuck as I can still enter information in my subject textbox even though the combo box before it is empty. but seems you can't included GIF animations without even more problems! I'm trying to enable textboxes in my form only if the field prior has been completed. I thought about using an animation aka the busy pointer. I even tried a second 'form', placing the progress bar in that, and running it via "Show" (as apparently, that should run as in background as it doesn't accept user interaction. But of course, whilst it's processing the "do" loop / external program, the "main" program is halted until the former terminates, (which is defeating the whole object) In short, the user clicks "Start" This executes an external program that takes about 20 seconds to run, (represented by the "do" loop at the top) At this point, the GUI appears 'frozen'. (I think it's to do with the "single thread" nature of the Powershell in PERL you could do a 'fork' which may solve the problem) Having spent about 8hrs trying different configurations, I've run out of ideas.
