Hi!

First of all, do not use the variable created with name that match to form name. This variable is usable only in design-time mode for debugging purposes to quickly view the properties and objects of the form. In run-time mode this variable is nto reliable for referencing forms, do not use it in the code in the future.

You can use the _Screen.Forms collection to check if some particular form is opened:

* form class load event
if this.lOnlyOneInstanse && custom flag property, set it to .T. if form could be opned only once
  for i=1 to _Screen.FormCount && loop through all opened forms
    if _Screen.Forms(i).Name == this.Name && check if this form name match to any opened form name
      nodefault && prevent this form from loading
      _Screen.Forms(i).Show() && show the instanse of the form with this name that is already opened
      return .F. && do not continue any more in this instanse of the object
    endif
  endfor
endif

HTH.

>I know there has to be a standard way to do this. Within my app I launch forms from menus, from command buttons within other forms, and by double-clicking areas of forms, all using the DO FORM command. I am using the following code in the LOAD event of some of my forms to prevent creating a new instance of the form if it already exists:
>
>IF TYPE("Reportselect") = "O" and !ISNULL(Reportselect)
> Reportselect.Show()
> RETURN .F.
>ENDIF
>
>Of course "Reportselect" is the name of this particular form. How can I use a generic version of this code in the base class for my forms.
