Visual FoxPro merupakan bahasa pemrograman yang sudah mulai ditinggalkan orang, tetapi, bagi beberapa kalangan masih dipergunakan, dengan beberapa alasan. Masukkan AccessTest untuk nama Data Source. Klik tombol Pilih, dan menemukan database Access yang akan digunakan. Klik OK, dan tutup Administrator ODBC.
Most VFP developers begin their careers by developing small desktop apps meant to be used by single users on a single machine. Indeed, I have several of these applications running right now. The likelihood of there ever being more than one user accessing the data at one time is remote.

On the other hand, there is a possibility that as the organization grows, you will eventually want that application to be able to handle multiple users. Let’s face it, the whole idea behind using a database is that you have a central repository for data that can be used by a number of users. Before you can move your app to a multi-user app, you will need some very basic changes: 1 - In your Main.Prg, you must SET EXCLUSIVE OFF. As the name suggests, if you SET EXCLUSIVE ON, you are asking that your database and tables be opened for the exclusive use of this user. That is the opposite of what you are trying to do here. 2 - When you open tables or databases, use the SHARED clause: OPEN DATABASE MyDatabase.DBC SHARED or USE MyTable SHARED. 3 - If you are dropping tables onto the form’s Data Environment, then you need to ensure that you set the.Exclusive property for that table to.f.
Now, there are a number of commands that require exclusive use of the tables. For example, PACK requires exclusive use of the table. “But wait,” you say. “If I cannot open the table exclusively, how can I PACK the table?” The answer is: “you don’t use the PACK command.” In your Main.Prg, you need to issue SET DELETED ON.
This will make it so your users do not get to see deleted records. VFP will simply “ignore” these deleted records so they do not appear for the users. You need to note that SET DELETED is one of those commands that is “scoped” to the data session. If you are only working in the default data session, a single SET DELETED command in your Main.Prg will suffice. On the other hand, if you are using a private data session in a form or report, you will need to go into the data environment and double click it to bring up the data environment’s code window, find the.BeforeOpenTables() method and add the SET DELETED ON command to this method.
Again, “But wait” you say, “I eventually need to get rid of those deleted records! I don’t want my tables half filled with deleted records!” At some point, you will need to PACK these tables – but you do not need to do this when there are other users trying to access the data.
I use something called a “Pack and Re-index” utility. This is a separate EXE file that runs as a scheduled (using Windows Scheduler) application once a month in the middle of the night when there are no other users on the system. Yes, in this application, I open the tables exclusively. Once the pack and re-index is done, it closes all of the tables, and the next morning, the users can go back to shared access. Another of these “basics” is the SET MULTILOCKS ON command. You will probably want to be able to modify several records at a time. This being the case, you need to be able to lock more than one record at a time.
