Hi all,

I am working on a project which will require some data entry for IP =
address (ex: 192.168.1.001). I will like to get some suggestions on how =
to handle this kind of data with some validations. I was thinking in =
having 4 fields to handle each segment and another field to store the =
whole IP, what do you think?

I would use a single text field. I am not sure the application
environment though.

thisform.text1.InputMask="999.999.999.999"

Procedure thisform.Text1.LostFocus
If !udfCheckAddress(this.value)
this.SetFocus
EndIf
EndProc

Function udfCheckAddress(pcAddr)
local x, lcSeg, retval
pcAddr=alltrim(pcAddr)

retval=.t.
lcSeg=""
for x=1 to len(pcAddr)
if substr(pcAddr,x,1)<>"."
lcSeg=substr(pcAddr,x,1)
else
if val(lcSeg)=0 or val(lcSeg)>=256
retval=.f.
endif
endif
next
return retval

Just my 2 cents. There may be much easier way to do it. If you want
the hassle of four fields, the validation can be much easier.

I'm not sure that would work too well. Since IP address octets range in
value from 0 to 255 I would think that 4 textboxes capturing numeric
data and checking for values between 0 and 255 would be the most user
friendly along with being the easiest to check for possible validity.
