Controlling a progress bar.

How can I control a progress bar on my form from another class I created?

For example, my main form calls a function in another class called SectionLister and in that class I have calls to other functions in another class called SubSectionLister. SectionLister figures out how many subsections it needs to parse using a hashtable with subsection URLs in it, and I want to be able to set the progress bar to the number of entries in the hashtable, then move the bar each time SubsectionLister.List is called with a value from the hashtable.

So I tried to Dim progressbar as formMain.progressBar1 but I can't. What's the right way to do this?

Pass the progressbar into the function as a parameter.

VB Code:

'in class
Dim _progressBar As ProgressBar
 
Public Sub DoSomething(ByVal progressBar As ProgressBar)
   _progressBar=progressBar
 
   _progressBar.Value+=1
End Sub
 
'in calling form
Dim t As New Test
t.DoSomething(Me.ProgressBar1)

You are the f***ing MAN! I had to pass it to a function that already took a parameter but I didn't realize I could pass it as an additional one.

VB Code:

ElseIf sectionSelected = 2 Then
            gamesTable = sectionLister.List(gamesUrl, Me.mainBar)
            gridMain.DataSource = gamesTable

That works just fine. I also had to step the bar from within the for loop I have that iterates over the hashtable in the sectionLister.List function and that worked like a charm. I LOVE VB.NET!!!

WOOHOO!

Peace,
