Hi Cetin,
I've looked over your code and I understand what each module is doing, but I am not sure where each module is being run from and in what order.

Where is this snipett being executed from:

* Assumes all aplication forms are in forms folder
* For forms that have a DE replaces 'ALL' DE method codes with
* custom BeforeOpenTables code
Clear
Clear All
Local lnForms,ix
Local Array arrForms[1]
lnForms = Adir(arrForms, "forms\*.scx")

TEXT to m.lcMethod noshow
PROCEDURE BeforeOpenTables
UpdateDE(this)
ENDPROC
EndText

For ix=1 To lnForms
Use ('forms\'+arrForms[m.ix,1])
Locate For Atc('dataenvironment',BaseClass)>0
If !Eof()
Replace methods With m.lcMethod
Endif
Use
Compile Form (arrForms[m.ix,1])
Endfor

Is SetDbPath a .prg? Is it being run from thr command window?

Could you explain how each transition from one to another?

Thanks,
Bob
