Hi Friends

I'm an addon DEVELOPING SAP 8.81, when generating an error generatedOpenFileDialog

El subproceso actual debe establecerse en el modo de subprocesamiento controlado simple (Single Thread Apartment, STA) para poder realizar llamadas OLE. Asegúrese de que la función Main tiene marcado STAThreadAttribute. Esta excepción sólo se desencadena

My code is as follows

Public Function abrirOpenFileDialog()


            Dim MyTest As New OpenFileDialog

            Dim MyProcs As Process()

            MyProcs = Process.GetProcessesByName("SAP Business One")

            If MyProcs.Length > 0 Then

                'For i As Integer = 0 To MyProcs.Length - 1

                'Dim MyWindow As New WindowWrapper(MyProcs(i).MainWindowHandle)

                Dim MyWindow As New WindowWrapper(MyProcs(0).MainWindowHandle)

                MyTest.Filter = "Text Documents (*.txt)|*.txt"

                If MyTest.ShowDialog(MyWindow) = DialogResult.OK Then

                    coForm.DataSources.UserDataSources.Item("txt_archiv").Value = MyTest.FileName




                End If



                oAplicacionSBO.SetStatusBarMessage("No SBO instances found.")

            End If

        Catch ex As Exception

            oAplicacionSBO.MessageBox("Error al Abrir OpenFileDialog. " & ex.Message)

        End Try

    End Function

Help Me!
