Delegate Method.

[Nanda_MR]

I am doing a program that completely depend on serial port. While data receiving event I m getting following error. The calling thread cannot access this object because a different thread owns it. for that I used delegate method. Problem solved.

CP_Text.Dispatcher.Invoke(New DelegateUiText(AddressOf UpdateUiCP))

    Delegate Sub DelegateUiText()
    Private Sub UpdateUiCP()
        CP\_Text.Content = Format(Convert.ToInt32(RxStr.Substring(1, 2), 16) / 100, "0.00") 
    End Sub

But I am using 25 labels and 2 datagrids and 12 textboxs. so i need write above 5 line for all controls so. Is any method, i can handle above error in single method or event? thanks in advance Nanda.

You could reduce the delegate-invoked code to one pair of methods for each property you want to update by doing something like:

Delegate Sub delSetText(ByVal theControl As Control, ByVal st As String)
Sub doSetText(ByVal theControl As Control, ByVal st As String)
    theControl.Text = st
End Sub
Sub InvokeSetText(ByVal theControl As Control, ByVal st As String)
    theControl.Invoke(New delSetText(AddressOf doSetText), theControl, st)
End Sub

then to set the text on a happyButton to "George", you would simply say InvokeSetText(happyButton, "George"). Nice and clean and easy.
