VB.net Prompt user using Windows form

Hi

I have a Windows Form that I use to prompt the user. It is loaded with a list that the user
has to make a selection from.
I have an OK button that then runs the rest of the code.
Is there a way to pause the code, show the form and then run the rest of the code
without havening to channel it through the OK button?

In essence, I want the Windows form to gather feedback just like the OpenFileDialog would in the
following code and gather feedback from the user
                      With Globals.ThisAddIn.oAUTOMATOR.OpenFileDialog1
                            .FileName = ""
                            .InitialDirectory = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
                            .Filter = Nothing
                            '.AddExtension
                            .ShowDialog()

                            sFileAndPath = .FileName
                            sPath = System.IO.Path.GetDirectoryName(sFileAndPath)
                            sFile = System.IO.Path.GetFileName(sFileAndPath)
                            oSource_File = sFileAndPath
                        End With
