Re: Conceptual subfile question

Jon,

The week that article came out our shop tried it, liked it and have never
looked back. We stopped using hidden everything and just use likerec
and eval-corr for inquiry and maintenance. Love it!

Bill

Boy you guys like to make it complicated!

Read this for a much simpler approach

The example there is for a single record update but the exact same method
can be used when handling subfiles. The only time I would ever consider
using hidden fields for this purpose in a subfile is if that “subfile”
were a web page and I was using to hold state information.

Your response is a great response and is well said.

I'd add this: I define a data structure made up of the input-capable

fields on the screen and also define a field named OrigFields. When I
write the subfile record I also populate OrigFields, which becomes a
hidden field in the subfile record.

That provides:
- an easy two-field compare,
- allows an easily implemented F5-Refresh,
- an easy way to check if any updated fields were changed at another

work station in the interim between the unlocked read and the locked
chain.

I save the subfile record out to the database. ...
