SAVING/STORING VALUES IN A VARIABLE & RESTORIN

[Rawlings]

Hi Everyone
Can anyone assist me on how to save values in a variable (numeric, character, etc), restore this variable anytime, use the value stored in it, change the value & resave it if I choose. I know how to create variables in a layout design mode I am not familiar on how to save a value in it & the value will remain in the variable even when A5 is not running. I am used to the VSAVE & VRESTORE funtion in A4 but I don't know if a similar command or funtion exists in A5. Any help will be greatly appreciated. Thanks in advance.

RE: SAVING/STORING VALUES IN A VARIABLE & REST

in your autoexec script, you can define global variables, like

dim global cnum as c 'for customer number
dim global rnum as n 'for record number

then, anywhere in your app, you can freely reference the variable's value and/or change it - it remains in memory for as long as your app is open

or you could name them

dim global vcCnum as c 'for customer number
dim global vnRnum as n 'for record number

then, in a script you can say cnum=parentform:customer_number.value 'setting it for the current client

then whereever you go in the app the variable's value will remain until you change it again.

Rawlings,

I don't believe there is a direct equivalent for Vsave or Vrestore, as you've grown accustomed to in Alpha Four.

Most simply store them in a table. If you build a script and name it autoexec it will be run each time the database opens. This script can open the table and retrieve the last stored values for each field, and then use them to assign the same values to a series of global variables.

Check this article at www.learn alpha.com for details:

By the way, if you're not familiar with www.learn alpha.com you would benefit from spending time there browsing the articles list.

Hi all,

Something funny happened. I replied to this thread earlier today and was able to see my comment added to the thread. But now (obviously) it's gone. A metaphor for life, perhaps. Fleeting.

In any case, I recommended two options:
-storing variables in a table, and
-storing them in the database which Ver. 5 permits.

To do the former consult the link Tom recommends. For the latter, see the online docs for A5_save_settings() and A5_load_settings().

Wonder if this one will stick.

Thanks Folks,
I will like to thank Martin, Tom, & William for your quick response/assistance to my variable question. I will implement all your suggestion into my application soon. Thanks.
