Problem in thread

Question

Hi

I start a thread in my main form and inside it I call a module, inside that module, I process some files, after each file, I call:

MainForm.IncreaseProgressBar

which is:

Public Delegate Sub IncreaseProgressBarCallback()
Public Sub IncreaseProgressBar()
If MAPIProgressBarX.InvokeRequired Then
   Invoke(Sub() MAPIProgressBarX.Value = MAPIProgressBarX.Value + 1)
Else
   MAPIProgressBarX.Value = MAPIProgressBarX.Value + 1
End If
End Sub

Simply does not work and progress bar won't go through!

Any workaround? :(

Answer 1

Consider looking at IProgress<T> using Report method. Check out a basic example here.

Hi @Sani Love , Try the following code to see if it helps.

MainForm.Invoke(New IncreaseProgressBarCallback(AddressOf MainForm.IncreaseProgressBar))

Best Regards.
