Dear friend,
I'm searching documentation about sharing of one or more variables between tasks.
Any advice?
Thanks in advance
Marco
For example In the first task (task1.exe) I have this
cVariab := "Marco Boschi"
and obviously when this task is running.....
In the second task would be fantastic a command like this
? GetOtherTaskVar( "task1.exe", cvariab ) //
? "Marco Boschi"
P.S. I'm serious 
The easiest way is to have a database that can be called from different .exe's and where you store those variables. You could also use a text file ( like an .ini ). Be sure to refresh your mem variables in the program from that file periodically.
Yes ... I do this, especially with my auto update routines. The CONFIG.dbf file holds variable data that may be used by 4 different programs. It resides on the server and is read at the clients. A timer provides for periodic updating when values change, and before certain operations, that data is re-read from the server, so I don't have to ever leave the client program to get the latest values.
Tim,
thank you for your interest.
The problem is: I wouldn't like to load and unload from the disk into memory variables.
It takes too long for what I do.
My goal is as follows: to load into memory an entire dbf table and perform fast wild searches.
I imagine this scenario in a server
First task
- initial load of the table into one single variable.
- for any change in the table must follow an update of the variable in memory
Second task
- waits for user's requests of searches from clients reading new records in a shared table
- perform the requested search into shared variable (in memory) and not into the dbf table
