In that case, I would reccomend you pass in the title and check the .Caption property instead of the name. If your captions are the same, well ... How does an end user differentiate between the two forms in that case? If they have to go to each form and examine the data displayed, that would be a bad design (IMHO).

>>>the _screen.objects(nindex)... allows to uniquely identify an object in the _scree but how can i know this 'nindex' for a form ?
>>>Is there a command which returns this number ? i'd like to get it in the init event of the form.
>>>
>>The only way I know of is to create your own function that looks in the _Screen.Forms[] collection and finds the form based on some criteria you pass (e.g. form title or name). But at this point you have the form and can get an object reference to it as Erik suggested in another post.

>>      endif
>>   Endwith
>>endfor
>>return luretval
