Programming Microsoft Outlook and Microsoft Exchange, Second Edition (DV-MPS Programming)

Outlook enables you to test your forms as you develop them. Since the design and run environment are built into Outlook, you do not have to compile or save your forms before testing them. You can start a separate run mode so that you can test the form's functionality while making changes to it in design mode. You can also enable multiple instances of your forms in run mode, which is useful if you want to try different versions of the form and test different areas of functionality. To test your forms in run mode, enter design mode and select Run This Form from the Form menu. Outlook will automatically create a new instance of your form in run mode. To get back to design mode, just close the running instance of the form. Figure 5-22 shows an Outlook form in both design and run modes.
