Use the Run Form command from the File menu to test a form that you are developing. The Run Form command runs any form, whether that form was created by you or generated by using the Form Wizard. The Run Form command is disabled:
When the form is in the latest version of a versioned schema
Until a form is loaded into the Painter; that is, selected for edit
To run a test of your form
Select the Run Form command from the File menu.
The form runs as though in runtime mode; that is, you can use it to enter data. When running a form, the following may apply.
It may fail if there is any dependency on another form or another process being run first.
If the form is an MDI child form, it is run inside an MDI test frame.
