Sergey,
That is one solution, but it has major limitations. What if the user tries to launch another instance of that form? Public variables are not a good thing.

Another approach is to create a non-visible object whose job is to launch and track forms. This object has a couple of methods in it named LaunchForm, RegisterForm, and RemoveForm. Your start up program would create the object;

* Startup
PRIVATE oForms
* CReate the form mngr
oForms = CReateObject("YourFormLauncherClass")
* Launch the menu
DO Whatever.mpr

READ EVENTS

The menu opions for a form would;

oApp.LaunchForm("TheFormYouWant")

The RegisterForm method would be called by the Form class in its Activate event and the RemoveForm would be called from the Form class's Destroy event.

For an example of this approach look at the TasTraders sample that comes with VFP.
