... display. Actually, they display very briefly when resizing the window but then they vanish leaving the panel showing through. I found that if I subclass TPanel and use the parent classes' paint method instead, it works fine. So there is apparently a problem with the paint method in the TPanel ...

Tim, If you are doing what Rao said, and if ::save() is a method of a TData or TRecord subclass, then you should not be making user interface code as part of the subclass, but rather passing the data object to the UI code. Remember that data objects should be models ...

Eduardo, Did you mean file locks or record locks? Either way, I use database objects. I wrote a subclass to TDatabase which adds many enhancements. I added some enhancements for record locking including automatic retries if a record is already locked. Personally, I aways ...

... code before and after every file lock in the program. That is, unless, you are using a database class. In this case all you have to do is create a subclass and add locking tracking. Then it gets used anywhere in the program that locking was used.

... So instead of oTDesc, just oDesc, or oDescrip, or even oDescription. The idea is to make the code more readable. An even better solution is to subclass TDatabase for each DBF file. So you do something like: CLASS TDescrip from TDatabase   method New()ENDCLASSMethod New( lShared ...

... have my old notes with me right now, but I will try to remember to look them up tonight for more specific information. It may be that creating a subclass of xBrowse would solve the problem. James

tData is always built from the latest tDatabase ... because it is a subclass.

CLASS TData from TDatabase

Thus, when I do a rebuild of the program, it will always be deriving from the current tDatabase.

... primary-key field containing a unique non-blank value. Use the primary key field to link to another DBF containing only a memo field. 2) Create a subclass of TDatabase (or TData) and write new save() and load() methods. In these methods you need to automatically lookup the memo field associated ...

Tim,

I see no reason it wouldn't work with data objects. We just need to subclass and add the password unlock and possibly a check to make sure the database is encrypted.

When time permits, I will test this to be certain.

... primary key record, and actually reading it. I.E. lock it, wait, read it using oDBF:load(). Or use both ideas. You can build all this logic into a subclass of TDatabase. Create a new Append method that automatically increments the primary key field and saves it to the newly appended record, then ...

... some informations from data to classdata in xbrowse so we can assign them once for all Two ways you can do this without modifying xBrowse. 1) Subclass xBrowse to your own class and use that class instead of TxBrowse in your app. create class MyxBrowse() from TxBrowse   method New()endclassMethod ...

... so it would be better if those static functions were defined as protected methods. Then the class is still fully encapsulated and we can also subclass and use those methods if needed. And, of course, they won't affect the use of your library with the same routines as functions. Regards, James
