Show multiple instances of the same form without any problems.
#Acrosync multiple instances code
As long as you code with encapsulation in your mind, you can That's a basic feature of VFPs class design and therefor multiple instances of a customer form is absolutely normal business for VFP. The whole reason of encapsulation is Multiple Inheritance. In VFP the reuse of a table doesn't create new filehandles, thus your point isn't really valuable.
First you are argueing about the waste of filehandles etc, but then recommend to do multiple instances of a whole application, which will surely put way more resource usage/waste onto the box. Seems today you're focussed with nitpicking on me :)Īgain I disagree with your view. The only disadvantage is a confusion in Datasession So I am rather opening several "global" tables under their name and generating app unique alias name for each other table which can be open several times and everything can live in Default Datasession then. Also multiple instances of one application is an easier solution than difficult implementation of multithreading to VFP app. One crash does not affect other instances.

The functionality you are describing as a big advantage of Private Datasession can utilize any Windows application when you execute it in multiple instances. I would need one Public Datasession.īut that's not the main reason I am replying to your post. Private data session also requires to open many more files than necessary - just imagine data dictionary, predefined lookup tables and conditions etc. Microsoft " Most Valuable Professional" from 1996 to 2009 This number is used by mysqldmulti to identify each instance, so it must be unique across the server. Or do you just allow multiple instances of an editform so that you can easily work on several customer records at the same time (Also good for comparing two records for duplicates etc)?įoxPro makes it very easy to create multiple independent forms with the help of the "Private Datasession" form property. To have multiple instances of MySQL running we must replace the mysqld group in my.cnf configuration file by as many mysql N groups as we want instances running, with N being a positive integer, also called option group number. Now what do you do? Tell theĬustomer "Hey, please call back in 5 minutes because I have to finish the updates on the currently displayed customer first, because that f***g program doesn't allow me to open up more than one instance of a customers form!" ou then have propably just
Why should this be foolish? That's a commomn scenario: You are editing a customers address in the customers form, and the phone rings and you have to immediately look up the data of that calling customer. I know it seems rather foolish of a user to open multiple instances
