Another time DataGrid.... not work ok in exe.

[tabbiati]

Hello to all,
I needed more information on the DataGrid:
I made a small application with a DataGrid and with a button
that adds a record to the DataGrid by taking the values of some field;
everything is working fine in development mode but once built the executable
visually everything is fine ( i see added record) but the next time you start application added records are not saved
( in development mode work ok).
This code is used to add data:

put field "Titolox" into gVTheDataB["Titolo"]
put field "Cognomex" into gVTheDataB["Cognome"]
put field "Nomex" into gVTheDataB["Nome"]
put field "Giornox" into gVTheDataB["Giorno"]
put field "Orax" into gVTheDataB["Ora"]
put field "Posizionex" into gVTheDataB["Posizione"]
put field "Presenzax" into gVTheDataB["Presenza"]

put 1 into theLineNo
dispatch "AddData" to group "DataGrid 1" with gVTheDataB, theLineNo
put the result into theNewIndex

I see a previous similar topic but i think that is not same thing.
I start to read PDF of DataGrid but now i am more confused....
Thanks

Bongiorno tabbiati,

standalones NEVER save themselves on any platform!

You need to export the complete data when the app closes and re-import when the app starts!
This is a common technique, so get used to it

Check this RunRev newsletter, you can adapt the principles (at least the place WHERE to save your data) to your needs:
http://runrev.com/newsletter/october/is ... etter3.php

If your datagrid is a TABLE then you can simply get/set the dgtext of grp "your data grid here" and save/read it to/from
a file in a directory where your app has write permission, see the newsletter!
If your datagrid is a FORM, then this will requre some extra steps.

And come back when you have more questions.


Best

Klaus
