Update label from mainform class with backgroundworker from another class

Question

I have two classes.

Public Class MainForm

     Private Project As clsProject


Private Sub btnDo_Click
   ...
   Backgroundworker.RunWorkerAsync()

End Sub
         


        

Answer 1

Try:

Me.Invoke(...)

instead of lbl.Invoke(.... I had to do this. This is my implementation:

Delegate Sub SetTextDelegate(ByVal args As String)

Private Sub SetTextBoxInfo(ByVal txt As String)
    If txtInfo.InvokeRequired Then
        Dim md As New SetTextDelegate(AddressOf SetTextBoxInfo)
        Me.Invoke(md, txt)
    Else
        txtInfo.Text = txt
    End If
End Sub

And this worked for me.
