Hi

I've added a barcode reader recognition which has partially started to work

I get 'Invoke or BeginInvoke cannot be called on a control until the window handle has been created.' error message on the line highlighted


Friend Sub AccessFormMarshal(ByVal action As String, ByVal formText As String)

AccessFormMarshalDelegate1 = New AccessFormMarshalDelegate(AddressOf AccessForm)
Dim args() As Object = {action, formText}

' Call AccessForm, passing the parameters in args.

MyBase.Invoke(AccessFormMarshalDelegate1, args)

End Sub

Thanks
