Using :Find you MUST :MoveFirst() before you issue the :Find() .. you might also use :Filter

Rick,
Adordd uses seek in the following way (also with relations).
It works just like dbfs any changes needed in app code. See the code
We will have another function adoseek(cKey) to build a recordset with the ckey expresssion as where clause
and adoseek() to revert to the previous recordset.
Its faster than the ado_seek() but you will need to insert these changes into your app code.

ADO RDD xHarbour

Antonio, Enrico, Lucas,
Do you have any experience use SELECT * FROM cTable with adUseServer and adUserClient ?
Does ADO load all rows? Is there a way to avoid that? CacheSize? MaxRecords?
I have now a new adordd version imitating 100% dbf behaviour, however Im afraid that during trials this will be slow because of the use of SELECT as explained above and the use of find to locate record number.
With adUseClient we can use ADO index property for field recno but I dont have any trials on this.
Besides this, with new version all browses in the app work without any changes.
The tester in our client says that with Oracle, although much slower than ADSrdd its ok.
In ADSoledb its slow!
In Mysql didnt tried yet.
The table average size of this application is 100.000 Recs some with > 700.000.
Can you share some of your experience?
Here you have alternatives:

Antonio,
Dbeval calls UR_EVALBLOCK that calls ADO_EVALBLOCK.
There is something missing because the block its not properly evaluated in SUM
Can you help me finding out whats the problem?
Is the RETURN correct?

Isn't uResult provided by reference ?
If not, then this value will be lost:
uResult := Eval( bBlock )
not sure if it will be also applicable to:
UR_SUPER_EVALBLOCK( nArea, bBlock, uResult )

ADO RDD xHarbour
|
UR_SUPER_EVALBLOCK( nArea, bBlock, @uResult ) maybe ?
|
ADO RDD xHarbour
|
Antonio,
I dont know if uResult it is provided by reference because its called from dbeval().
Dont know why but UR_SUPER_EVALBLOCK( nArea, bBlock, uResult ) works! (without @)
Adordd its almost ready ! Now adordd its a true Rdd!
There are big differences from previous posted version.
Its much slower than DBF or ADS with few users but completely workable and the difference begin to decrease as more users are getting in.
Ill report after the trials.
The converted app is running quite ok with zero changes in the logic of the code.
The only code changes we had to make were for locates and some index creation expressions, nothing else!
Now we are testing every app routine and Im sure that we will still find some small bugs.
We are still with some minor problems like the display of numeric fields on the browses (right just instead of left just) to be solved.
Ill post the last version soon!

Antonio, Mr Rao,
Im having a problem with Numeric fields Len and Dec.
Ive found this in adofuncs.prg:
Max( 19, oField:Precision + 2 )
What does it mean?
NumrericScale = Nr of decimal places
Precision = Total field len
numfield N 11 4
Precision = 11
NumericScale = 4
Len = 11
Dec = 4
Making numeric fields for calculations it round always decimals to 0 although field len and dec are correct.
What can we do?

ADO RDD xHarbour

Antonio,
I don´t understand the change in LOCATES:
IF RDDSNAME() = "ADORDD"
hb_adoSetLocateFor( "pessoa = "+"'"+(MeuNome())+"'")
[b:24kjbi6a] locate for "pessoa = "+"'"+(MeuNome())+"'" [/b:24kjbi6a]
ELSE
...
We have to keep LOCATE FOR as DBFCDX, so not to use hb_adoSetLocateFor.
Or provide it for complex locating, but not for ordinary use.
If we have to start changing code, there is no RDD compilant.
Thank you.
|
ADO RDD xHarbour
|
Lucas,
Please remember:
hb_adoSetLocateFor is needed as LOCATE calls in adordd:
ADO_SETLOCATE( nWA, aScopeInfo )
ADO_LOCATE( nWA, lContinue )
Unfortunately aScopeInfo doesnt supply the cFor condition only bFor condition thus we need to set it up before with hb_adoSetLocateFor.
Let me check what we can do.
|
ADO RDD xHarbour
|
Antonio,
Thnak you for your attention.
At least, it should support LOCATE FOR Upper(FIELD->City) = Upper(cCity).
|
ADO RDD xHarbour
|
Lucas,
I ve just recheck it and I dont see any other alternative.
You have to consider :
LOCATE FOR Upper(FIELD->City) = Upper(cCity).
This s passed to ADO_SETLOCATE in aScopeInfo as a code block.
We need hb_adoSetLocateFor to have it as a string.
But another problem is the hb_adoSetLocateFor( <(for)> ) (adordd.ch) needs to receive it as a string:
" Upper(FIELD->City) = Upper(cCity)"
This cant be evaluated because the variables are out of scope at ado framework.
This we must sent as for other rdds like ADS with the value of that var and not the var itself thus you will have to do:
"Upper(FIELD->City) ="+"'"+ Upper(cCity)+"'"
Then the string would be:
Upper(FIELD->City) ='LONDON'
The same will happen in index expressions with vars.
Sorry there isnt any other way.
For us no problem because the app worked already with ADS and it was already doing that.
Nevertheless this should not be a problem because its a very fast change in the app code and does not break any logic of it that's why I proposed the foloowing way of change it:
IF RDDSNAME() = "ADORDD"
//NEW EXPRESSIONS FOR ADO
ELSE
//AS ALREADY WRITTEN CODE
ENDIF

I am moving our disucssions to this thread to keep them at one main place.
You said:
[quote:2h6acl7o]
(ownd:numera)->dataultmov is 28/04/15
dDataM is 28/04/15
if (ownd:numera)->dataultmov > dDataM
msginfo("Data do ult doc "+dtoc((ownd:numera)->dataultmov)+CRLF+;
"Data deste doc "+dtoc(dDataM) )
endif
The code inside the IF should never be executed but it is and the msginfo shows both with the same date 28.04.15.
What might be the reason?
[/quote:2h6acl7o]
First recommended caution is to keep always Century on.
Most date fields in various SQL servers store acutally date-time values, not pure truncated date values. Please keep in mind that I said "most" not "all".
If for some reasons, the value stored in the field is 28/04/2015 00:00:00.001 then this field value is greater than pure date 28/04/2015. Years back I struggled till I found that xHarbour was adding one extra milli second. ( I do not know if this is ok now)
We need to be extra-cautious while dealing with dates in sql databases. For the purpose of ADORDD, please return truncated date ( with valtype 'D') when the FieldType is "D" and full value with valtype 'T' when the field type is 'T'.
I suggest you return FW_TTOD( <fieldvalue> ) when the FieldType is 'D' and FW_DTOT( <fieldvalue> ) when the field value is 'T'. We use this in our XBrowse, TDataRow and TRecSet so that users are insulated from this behavior.
We need to keep this in mind when preparing SQL statements comparing Dates.
For example, SELECT * WHERE INVDT BETWEEN '2015-04-01' AND '2015-04-30' may totally exclude all transactions that took place on 30th Apr 2015. Because this is actually translated as INVDT >= '2015-04-01 00:00:00' and INVDT <= '2015-04-30 00:00:00'. Naturally this query ignores transactions from '2015-04-30 00:00:00.001' till '2015-04-30 23:59:59.999'
This is just an example to show how deceptive can be date comparisons. In addition MS Sql server has a very awkward habit of storing '2014-04-01' internally as '2014-04-01 12:00:00' in the field.
So, the safer construct is SELECT * WHERE INVDT >= '2015-04-01' AND INVDT < '2015-05-01'. I still see many amatuers committing this mistake which turns out to be a blunder in real life situations.
I hope if you keep this points in mind, everything will work as expected.

[quote:2sov47l7]I´ve tested it and it works perfectly with adUseclient and adUserServer cursors.

Extracts:
[quote:2sov47l7]
adLockPessimistic 2 This value indicates pessimistic locking, record by record. The provider does what is necessary to ensure successful editing of the records, usually by locking records at the data source immediately after editing.
This lock type is supported by the Microsoft® OLE DB Provider for AS/400 and VSAM and the Microsoft OLE DB Provider for DB2. However, the OLE DB Provider for AS/400 and VSAM internally maps this lock type to adLockBatchOptimistic.
[/quote:2sov47l7]
and
[quote:2sov47l7]
The adLockPessimistic setting is not supported if the CursorLocation property is set to adUseClient. If an unsupported value is set, then no error will result; the closest supported LockType will be used instead.
[/quote:2sov47l7]
You said:
[quote:2sov47l7]
So we never call :Update() in ADO_PUTVALUE and ADO_APPEND and the :Update is then called only ADO_UNLOCK. Right?
[/quote:2sov47l7]
Good Idea.
[quote:2sov47l7]
The app Im converting gets all the new records an locks and then goes through the Locklist array of each table processing each replace.
Since we move the record we lost the physical lock right?
[/quote:2sov47l7]
Yes.
It appears multi-record locking does not seem possible in ADO. Anyway you need to keep experimenting more on this, simultaneously working as two users on the same table.
[quote:2sov47l7]
Starting a transaction can eliminate this ?
[/quote:2sov47l7]
Transactions and locking are two different things altogether.
All updates within one transaction block either they get written or abandoned but never written partially. Normally used for multi-table updataions with the same connection.
Talking about transactions, they work for a single connection. If we open recordsets with connection string each of them will get a separate connection.

To avoid apps code change then we could do it:
SELECT * WHERE INVDT BETWEEN '2015-04-01'+'00:00:00:000' AND '2015-04-30'+'23:59:59.999'
adding the time part to the date at adordd.
Resuming we always add at adordd the time part of the date like that. Right?
Thanks so much for your help and expertise.

[quote:f0elt87e]Glad to know it is working well with both client and server-side. [/quote:f0elt87e]
It works in the sense of the locking (with 2 users the 2nd cannot edit) but changing order focus we build a new recordset with the order by clause and closing the current one throws an error.
Also if we get the locks and move to other records we loose it.
I think the only alternative is to have another field or a table to do it but we still didn't find how.
Do you have any idea?
Also using adUseclient seems not to work ok with our browses. adUseServer ok.
But adUseServer doesnt work with Browse() in ACCESS.
Dont know why.

New adordd version with working locking as dbfs at <!-- m --><a class="postlink" href="https://github.com/AHFERREIRA/adordd.git">https://github.com/AHFERREIRA/adordd.git</a><!-- m -->
This is still on trial and its working quite well on heavy transactions many records in many tables.
It assures completely record locking and concurrent access control like any other rdd.
The drawback is that we must use a dbf table in a network share with another rdd for this to work.
Its very small recsize only 50b and has a recycle scheme for records not needed.
Still have some issues with dates and NULL values in adordd.

This function calls ADO_APPEND but the nWA received its a new one.
Probably this function selects a new area to copy file to.
Can we somehow change it or do we have to write a replacement from scratch.
Where can I find this function?

Antonio,
Thanks for the code.
adordd its working almost perfectly.
Antonio, Mr Rao,
But I've still 2 pending problems:
1) Fields N without any decimal returning 2 decimals. (xxx.00) Do you have any idea what might be the problem.
2) Locates. Can you check the adordd.prg ado_locate to see what might be the problem?
If we do :
[code=fw:3aktb8z7]<div class="fw" id="{CB}" style="font-family: monospace;"><br /><span style="color: #000000;">(</span>calias<span style="color: #000000;">)</span>-><span style="color: #000000;">(</span>__dblocate<span style="color: #000000;">(</span> <span style="color: #000000;">{</span>|| namefiled->name = cNname<span style="color: #000000;">}</span> <span style="color: #000000;">)</span><span style="color: #000000;">)</span><br /> </div>[/code:3aktb8z7]

Antonio, Mr Rao,
[quote:2opahsr4]Try to check the size of the field and use int() when its not a decimal[/quote:2opahsr4]
Solved!
In adofuncs.prg you have:
[code=fw:2opahsr4]<div class="fw" id="{CB}" style="font-family: monospace;"> nLen := <span style="color: #0000ff;">Max</span><span style="color: #000000;">(</span> <span style="color: #000000;">19</span>, oField:<span style="color: #000000;">Precision</span> + <span style="color: #000000;">2</span> <span style="color: #000000;">)</span> </div>[/code:2opahsr4]
Shouldnt it be:
[code=fw:2opahsr4]<div class="fw" id="{CB}" style="font-family: monospace;"> nLen := <span style="color: #0000ff;">Min</span><span style="color: #000000;">(</span> <span style="color: #000000;">19</span>, oField:<span style="color: #000000;">Precision</span> <span style="color: #000000;">)</span> <span style="color: #B900B9;">//</span></div>[/code:2opahsr4]
Otherwise we will have all fields much bigger because the minimum it will be 19.
Why not only oField:Precision?

Thanks. I am correcting Max to Min in adofuncs.prg.
+2 is for ( 1 decimal place and 1 minus sign )

Lucas,
Always both with same size an order.
One for ado framework the other for all usual index functions to work correctly.
The SET ADODBF TABLES INDEX LIST TO must follow the (x)Harbour usual syntax.
The SET ADO TABLES INDEX LIST TO its for SQL it might even contain SQL functions.

Mr Rao,
[quote:joq2j8lc]+2 is for ( 1 decimal place and 1 minus sign )[/quote:joq2j8lc]
In dbf when we say field,"N" ,11,4 the total length f the field is 11 but in fact one is taken for the "." decimal
so we only have 6,4 and if we want a minus we only have 5,4.
Shouldn't we use the same criteria in adordd ?
Besides that if we create a field, "N", 10 ,2 in ACCESS in adofuncs it is considered as "MONEY" why?
|

Money must be used with 2 decimals because there is a bug with Access.

Antonio,
What are the differences between SET ADO TABLES INDEX LIST TO and SET ADODBF TABLES INDEX LIST TO?.
Tryadordd.prg explanation is not clear.
Also, in last versión locking does not work.
Also, OrdSetFocus() fails too.
I suggest you to try with XBROWSER FASTEDIT.
With this command, you will be able to add, modify, delete records... etc and you will be able to find bugs.
Thank you.
|
ADO RDD xHarbour
|
Lucas,
Please check your version.ADOVERSION() in adordd and inform.
SET ADO TABLES INDEX LIST TO these are the indexes for adordd without any dbf expressions for ado framework
Ex index expression "date+nrcod+id"
SET ADODBF TABLES INDEX LIST TO are the indexes with dbf expressions as you use in your dbf application
Ex index expression "dtos(date)+str(nrcod)+id"
Dont forget that the ADODBF are the index expressions to be evaluated like Indexkey() or &(indexkey())and all index functions.
Locking should be working although with some bugs now corrected.
It was not releasing all locks.
If you dont have any autoinc field indicated to adordd you will get problems.
Orsetfocus() is already working ok since the last couple of verions.
We ve using it without any errors.
Could you post the error and the index expression?
I dont work with xbBrowse in this app and I dont have it.
Ill post a new version today working ok with:
Dates and numbers
Exclusive use
Locking
Missing to do:
append from
copy to

So SET ADO TABLES INDEX LIST TO and SET ADODBF TABLES INDEX LIST TO must be defined both or just one?.

How do you call it from app?

I need your help.
What are these doing?
/* non WorkArea functions */
#define UR_INIT this I know!
#define UR_EXIT 95
#define UR_DROP = ADO_DROP (DROP TABLE OR INDEX)
#define UR_EXISTS = ADO_EXISTS (TABEL EXIST?)
#define UR_RENAME 98
#define UR_RDDINFO This I kow
In previous version of adordd from Fernando and Miguel they are redirected to ado_.
I think these are rdd driver related functions so that redirection is wrong.
Can you confirm?

You have to check how those commands are translated:
[quote:5wcw9ss0]#command APPEND [FROM <(f)>] [FIELDS <fields,...>] ;
[FOR <for>] [WHILE <while>] [NEXT <next>] ;
[RECORD <rec>] [<rest:REST>] [ALL] ;

__dbDelim( .F., <(f)>, <(delim)>, { <(fields)> }, ;

Now look in Harbour source code for __dbDelim() code

It seems to me that this has to do with rdddriver and not table.
I think we dont need this. Right?

It looks like a cleaning on exit if needed.
If you don't need it to clean anything, then you don't need it.

Antonio,
I'm working "copy to" but guessing what to do because there isn't any documentation.
Please inform what is in aFieldsStru I see some code blocks but I have no idea what it is.
__dbTrans( nDstArea, aFieldsStru, bFor, bWhile, nNext, nRecord, lRest )
are these parameters correcto for UR_TRANS?
Also parameters for UR_TRANSREC and what is for.

Elvira,
Please try:
SET ADO LOCK CONTROL SHAREPATH TO "C:" RDD TO "DBFCDX" //cant use final "\"
SET ADO TABLES INDEX LIST and SET ADODBF TABLES INDEX LIST TO
the name is of the table not the alias.
And add HB_RECNO when creating the tables. This field its not auto creates by ado.
Please let me know result.
Thanks

I did those changes, and I still get:

By the way, in order to have ADORDD more clear, SET ADO LOCK CONTROL SHAREPATH should be by default HBDIRBASE(), without needing to specify it. The same for SET ADO DEFAULT RECNO FIELD.
Thank you.

Elvira,
You must do it like this:
Please note table1 instead of test2 in SET ADO... TABLES as the indexes are related to tables not to DBs and ID field in dbcreate.
Like this should work ok.

Elvira,
Its a bug !
Take out test2.mdb; from dbcreate.
DbCreate( "table1", { { "FIRST", "C", 30, 0 },;
{ "LAST", "C", 30, 0 },;
{ "AGE", "N", 8, 0 },;
{ "ID" ,"+",10, 0} }, "ADORDD" )
Im correcting it but like this its working here.
Let me know if it worked.
Thanks.

If you want keep things the same way please replace in adordd in function ado_create
IF( ALLTRIM( cDataBase ) == "" ,cDataBase:= t_cDataSource, cDataBase )

ADOVERSION() Returns adordd version
hb_adoRddGetConnection( nWorkArea ) Returns the connection for the workarea
hb_adoRddGetRecordSet( nWorkArea ) Returns the recordset for the nWorkArea
hb_adoRddGetTableName( nWorkArea ) Returns tabe name for the nWorkArea
hb_adoRddExistsTable( oCon,cTable, cIndex ) Returns .t. if table or table and index exist on the DB
hb_adoRddDrop( oCon, cTable, cIndex, DBEngine ) Drops (delete) table or index in the DB
hb_GetAdoConnection() Returns ado default connection
Exclusive its only working if you try to open the table in another instance of app.
Updating records its still not verifying it if table its exclusive and since it does not find a lock record throws error.
All this only working next post tomorrow.

Antonio,
I can´t add, modify or delete records.
I get that errors.
I open the table like this:
[code=fw:8lf6z6gz]<div class="fw" id="{CB}" style="font-family: monospace;"><br />USE table1 <span style="color: #0000ff;">ALIAS</span> <span style="color: #ff0000;">"TEST2"</span> <span style="color: #00C800;">NEW</span> <br /> </div>[/code:8lf6z6gz]
And:

Both cases I get errors.

Here tryadordd and variants are working perfectly.
I can add modify and delete records with browse() or with append and replace .
I dont work with xBrowse
Did you tried with browse()
Can you navigate well with xbrowse ?
Can you send to my email your trial prg?

ADO RDD xHarbour
|
Antonio,
Have you checked my sample?.
Thank you.

ADO RDD xHarbour

Elvira,
Yes and it runs ok here.
I ve found out that the problem is with cursorlocation because with ACCESS aduseclient you can not :update()
so I've change it to adUseServer but with adOpenKeyset because with adOpenDynamic ACCESS also does not work correctly.
In my tests with MYSql everything its ok.
Also since locks are enforced using Browse() you need to pass the deleteblock otherwise adorddd will raise "lock required" error as Browse() deletes without call dbrlock().
Exclusive use is still under development because it wasnt work correctly.
Locks have been readjusted and now seem to work ok.
When creating views please remember that you need to have also a autoinc field to be used as recno so you can include it in the "as select" statement.
Please send me your email and Ill send you now last adordd.
Did you managed to navigate correctly with xbrowse?

ADO RDD xHarbour

Mr Rao, Lucas,
How can I use adUseServer cursor with MySql?
I can only work with adUseClient.

ADO RDD xHarbour

New version adordd.prg posted <!-- m --><a class="postlink" href="https://github.com/AHFERREIRA/adordd.git">https://github.com/AHFERREIRA/adordd.git</a><!-- m -->
Its very imortant that you indicate in adordd.prg in the several places with the cursorlocation the type of cursor you need to your DB.
Not choosing the right cursor the browses become irregular.
Please remember that all browse positioning is based on absoluteposition thus a cursor that can not support it doesnt work.
Also you need a cursor that supports update() and requery().
The cursors defined in adordd support:
ACCESS
MYSQL
ORACLE
Changes:
Locks now work as it should.
Exclusive use in progress not validated
Using Browse() you must pass delete block because it does not lock the record and adorddd raises a lock required error.
Also when you change the index key value the browse() does not re-position immediately the grid. Click right or left arrows.
adordd has been working ok with :
ACCESS
MYSQL
ORACLE
both in internal network and internet and its ok.
Internet a little slow but not crawling with tables 30.000 recs.
You must find which are the best parameters for your case and adjust it in ADO_OPEN
Look for:
[code=fw:1sp69mki]<div class="fw" id="{CB}" style="font-family: monospace;"><br /> <span style="color: #B900B9;">//PROPERIES AFFECTING PERFORMANCE TRY</span><br /> <span style="color: #B900B9;">//oRecordSet:MaxRecords := 60</span><br /> <span style="color: #B900B9;">//oRecordSet:CacheSize := 50 //records increase performance set zero returns error set great server parameters max open rows error</span><br /> <span style="color: #B900B9;">//oRecordset:PageSize = 10</span><br /> <span style="color: #B900B9;">//oRecordSet:MaxRecords := 15</span><br /> <span style="color: #B900B9;">//oRecordset:Properties("Maximum Open Rows") := 110 //MIN TWICE THE SIZE OF CACHESIZE</span><br /> </div>[/code:1sp69mki]
Please post your comments and findings.

Lucas,
How can I set value for "Maximum Open Rows" with MySql?
Is it possible with this property that the server only returns blocks of rows as they are requested?
Can this increase performance?
Thanks
|
ADO RDD xHarbour
|
Mr Rao, Lucas,
We found a performance problem with adordd trials.
The issue is that ADO_RECCOUNT (reccount() or lastrec()) sends a sql SELECT MAX(FIELD USED AS RECNO)
This is delaying quite a bit all browses mainly on WAN because gets called many times.
Taking this out the browses are quite fast.
Is there a way to question the DB if table has been updated and only then adordd sends the sql SELECT?
Or may be a faster way to question the DB ?
Im trying it with MySql over LAN and WAN and the difference in browses performance its huge.
|
ADO RDD xHarbour
|
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¿-

Also the "hbusrrdd.ch" are not present at xHarbour (only usrrdd.ch)
What to do?

[quote="lucasdebeltran":ju475lui]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¿-[/quote:ju475lui]
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

[quote="byte-one":9do002tf]Antonio, congratulations for your work!!!
I test to compile the adordd.prg with xHarbour and become many errors:
Also the "hbusrrdd.ch" are not present at xHarbour (only usrrdd.ch)
What to do?[/quote:9do002tf]
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,
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.
