Question How to access labels through backgroundworker_DoWork?

[skyfe]

Hi,

Was wondering: How can I set for example a value of a label within the progress that my bagroundworker does? So for example my backgroundworker is scanning files (in my case) and I want it to set label1.text equal to the name of the file it's scanning at that moment, but how do I do this? because when I do like:

Private Sub bgwScan1_DoWork(ByVal sender As Object, _
ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgwScan1.DoWork

[... some code ...]

label2.text = foundDir

[... some code ...]

End Sub

Then it says "access denied" or something. So how do I change the label2.text with my backgroundworker progress?

Thanks in advanced,

Skyfe.

Set the BackgroundWorker's ReportProgress to True in the designer.

In the DoWork event

Me.BackgroundWorker1.ReportProgress(0, foundDir)

In the ProgressChanged event

Me.label2.Text = e.UserState

Thanks a lot! It works!

Thanks so much, will be using this, and I guess I can use 2 backgroundworkers at same time, right?

Yes you can.

Ok thanks, well just found a way to do it with only 1 backgroundworker, while using 2 progressbars and 2 subs ^^ With using the e.UserState variable, reporting the progresses into their and when progresspercentage = 0, then the e.UserState would give the progress of the 2nd progressbar instead of the first, and update that one, etc., and so worked
Well, Thanks for the help, got it all working now
