  • 1. stepping through records retrieved using SQL
    I'm using Delphi 5 and need some help in using SQL. - as follows: How can I step through records that have been retrieved using a SQL command. I believe this is done be controlling the cursor, but I have no idea how to do this.
  • 2. TDBGrid drag 'n drop
    Is it possible to drag and drop from a TDBGrid component? I can't get it to work. The component reacts to doubleclick but not mousedown, and if I do begindrag in a cellclick event nothing happens either. Thanks.
  • 3. ACCESS dbase
    Hi, When I connect a TTable to the Dbase IV tables I simply set the databasename property to the actual dbf-file (path+filename) from Delphi. This works fine. When I try to do the same thing with ACCESS 97 database / table files I get an error message "invalid parameter" when I try to set connected to true. What am I doing wrong ? Thanks for any help, Jur van Oerle
  • 4. Either BOF or EOF is true
    Using TADOQuery and an Access database with MDAC 2.6 and Jet Engine version 4.0 When I run the code below I get the error 'Either BOF or EOF is True' when I try and close the ADOQuery. I can only close it by going back one record with genQ.prior; If I change the query so that no results are returned, I am unable to close the query at all as both BOF and EOF are true. with genq do begin close; sql.clear; sql.add('Select ADDRESS2 from memberlist group by ADDRESS2'); open; wwDBComboBox7.items.Clear; while not eof do begin if length(fields[0].asString) > 0 then wwDBComboBox7.items.add(fields[0].asString); next; end; close; // ERROR HERE end Any suggestions as why this should be gratefully received Richard
  • 5. Delete Record? Confirmation
    I have a D5 navigator connected to an Advantage Data Base. When the user clicks the - (delete) button the "Delete record?" conformation appears. How do I turn this off? Or ... can I modify the Question? I also need to delete a bunch of detail records that are connected to the master (above). I'm assuming the "Before Delete" in the DB is the best place for a couple SQL statements to accomplish this... right? Thanks, Craig.

I had no idea it was a common problem, but I'm certainly glad to hear that
it is.

May I bother you to instruct me as to how one goes about searching the
newsgroup archives?

This is a known problem, and has been discussed much in threads in this
forum, in borland.public.bde, and in other forums.  Search the newsgroup
archives for "insufficient disk space" or "4G limit" and you'll find
plenty.  There are also suggested work-arounds, and I think one is
a download available from Code Central.

Thank you Bill and Rick.

I found this on "Rick's dBase page" (www.goldenstag.net/dbase/#Source)...
has anyone used this fix and care to comment?

BDE "Insufficient disk space" Error Fix
The BDE in all releases earlier than 5.2.0.2 (the version that ships with
dBASE Plus 2.5 and later) and later releases one assumes, has an error that
can occur if you or your users have free disk space on the hard drive that
is an exact increment of 4 gigabytes (i.e., 4, 8, 12, 16 ...). The file
BDE4GigFix.zip includes the .DLL file that solves this issue (it's a "patch"
for the BDE), and also a small program that will load it. Details are in the
file "BDEFix.prg" contained in the .zip file. Note that if you have dBASE
Plus 2.5 or later, this should not be an issue, and you do not need this
file.

I ran into the problem on occasion and just copied some file to the drive to
change the size of the free disk space.  It happened so infrequently, that
the biggest issue I had was to remember what to do when it happened..
