Ignacio,
can you help?
I hold some dbfs open during the runtime and like to open one of them again
in a new workarea for browseing the indexed data with TDBBrowse and
TDbfDataSet.
The problem is, that in this case Ctrl+PgDn TDBBrowse doesn't show the last
record in the index.
Please take a look to the sample.
Click on the "GesList"-button to open the dialogbox with the TDBBrowse.
Push Ctrl+PgDn - the oDataSet:KeyNo shows 676, the last record in the
indexfile.
But the last row of the TDBBrowse shows the data from KeyNo 530 and not from
676.
What is wrong with my code?
Regards
Ingo

Ingo,
After 1 hour searching I found the bug. Is a xHarbour bug. Just change the
following code on your sample:
METHOD FormInitialize( oSender ) CLASS GesList
With Object ::oData
:Open()
:lReUseDel:=.F.
:GoBottom()
logdebug( :Recno() )
:Skip()
logdebug( :Recno() )
End with
RETURN Nil
First LogDebug() shows record number 229. After the SKIP the record number
should be the same since is the end of file, but you will see that it jumps
to record 676.
I know there are a lot changes on xHarbour CVS right now, and that is the
reason why they can not publish the first RC. I suggest to wait until that
RC is released.
Regards,

Ingo,
José Giménez did some research and found the real problem, you are using the
ALIAS in the index expression. Since you open the table twice the second
table is openened with a diferent ALIAS, but its index points to the first
table openened. Quite complicated.
Just change the index expression to:
FIELD GESETZ
INDEX ON UPPER(GESETZ) TAG WDGES TO wdges
