Here's code that might work better for you:

CREATE FORM (myform) NOWAIT 
nObjs=ASELOBJ(aObjs,1)
nIdx=0
FOR i = 1 TO nObjs
   IF UPPER(aObjs(i).Class) = "FORM"
      nIdx=i
   ENDIF
ENDFOR
aObjs(nIdx).Caption="I can change the form's caption in developer mode!"

Note use of the ASELOBJ function.....







>In VFP 6.0 SP5 (or SP3?) the following code worked:
>
>MODI FORM (myform) NOWAIT
>
>FOR ln = 1 TO _screen.FormCount
> IF _screen.Forms(ln).Name = "form1"
> lo = _screen.Forms(ln)
> EXIT
> ENDIF
>ENDFOR
>lo.Caption = "I can change the form's caption in developer mode!"
>
>I could run this code from within an APP, EXE or PRG and use it to modify the form in design mode. But in VFP 7.0 the form being modified is not shown in the _screen.Forms collection.
>
>Was this an undocumented feature that was taken out of VFP 7.0? Will it be in VFP 8.0? I was able to create several form builders using this technique and they have saved me hours.
