Antonio,

I have not been able to test last version due lack of time. Does it work with Access now?. Which RDBMS have you tested?.

Regarding configuration optimization settings, please review adofuncs.prg Fw_OpenAdoConnection and FW_OpenRecordSet. They are high optimized and work very well. Also, for a WAN connection, the key is to have a connection with low ping, such as cable or fiber. Good DSLs work fine too.

About xBrowse speed, yes, it calls very often reccount(). Mr. Nages could provide more insight to it.

Have you checked out XBROWSER FASTEDIT¿-

It works with ACCESS the problem was only with the chosen cursor.
Now I'm only working with MYSql and its perfect. It works also with Oracle.

Performance without ADORECCOUNT its excellent.
Im trying to find a solution for it.

Concerning Xbrowse I dont work with it but there is any reason not to work ok.
Please let me know what is the problem with it ?

In adordd its only missing:

USE EXCLUSIVE
APPEND FROM
COPY TO

We are still clearing code.
I'll post today a new version with these corrections and hbussrdd.ch.

Thanks for your help.

Antonio,

Latest version from 06 seems much better.

I found a bug at dbcreate, you are not distinguishing Database and Table, so dbcreate fails.

Also, command SET ADO TABLES INDEX LIST TO <array> and SET ADODBF TABLES INDEX LIST TO <array>have been changed?. I can´t see the difference.

Also, SET ADO LOCK CONTROL SHAREPATH TO should take by default hb_dirbase(), so It won´t be called unless the programmer needs to change paths.

In my opinion, the less settings the more easy for new programmers to test it.

Thank you.

Lucas,

Lucas,

adordd works mainly with cursor adUseClient.

This brings a problem because new and deleted records by others are not seen.

Deleted records its not so difficult because in editions or transactions when we lock we do resync and if there is an error we requey and locks fail so edition or transaction doesn't not proceed.

But with new records...
We are studying a way to trigger that and requery again the recordset when needed.

As ADO expertise do you have any solution or idea for this?

Thanks for your precious help.

Antonio,

About Append from, please review function fw_dbftoado().

About refreshing, yes it is a behaviour in ADO, but xBrowse does refresh when scrolling. Also, I do refresh Recordset after adding of editing records, so in my opinion it´s not an issue.

Thank you

Where can I find it?

What you mean by refreshing is it requery ?
Thus if other user add new record you will only see it after adding or editing?

Antonio,

At source\adofuncs.prg

function FW_AdoImportFromDBF( oCn, cDbf, cAdoTable, cColPrefix, nMultiRowSize, aFields )


function FW_AdoExportToDBF( oRs, cDbf, lEditStruct )


In xBrowse yes. But that´s not a problem, in DBFCDX you have to issue a refresh() too.

xBrowse handles it very good with ADORDD. You should try latest xbrowse.

Lucas,

In the app we are working browses are not a problem. All work well without a single changed line.

My worry is with transactions.

The app works 99% like this:

First closes and add all records to all tables necessary to the trans.
If all goes well loop through those records in the several tables and replace values

Lets say a another user add a line to an order before its locked.
When I initiate transaction locking the order that new record does not exist in my set yet.
Thus will not be taken in account in my transaction.

Dont you think this is a potential problem?

By the way I have xbrowse code here and I cant see any :Requery
