Foxpro screen exist

[kitnba]

I am using Menu editor, I don't want user click my menu item twice.
If 'A' program is already on screen , I don't let him to run 'A' program again.

How can I do it, or check the Progrma is already Exist now ? or I can disable the Menu item?

Thanks

Hi kitnba,

On the Init of you form you could so something like

SET SKIP OF PAD _EDIT OF _mysysmenu .F.

and at the destroy event of you form,

SET SKIP OF PAD _EDIT of _mysysmenu .T.

For more information check out the MSDN, SET SKIP.

Hope this helps.

Creeder's example isn't the first solution I thought of, but its the best and cleanest way to get the behaviour you want.

If you ever do need to look at the list of executing programs, though, you can use the PROGRAM() function. This example loops through all running VFP programs and displays their names on the screen:

for nPrograms = 1 to program(-1)
	? program(nPrograms)
endfor
