 Posted: Thu Jun 22, 2006 9:32 pm Post subject: is there any function in JBuilderX like dataset.disableCont |
 |
|
In Delphi, if scrolling a large dataset, we can call disableControls and
after scrolling, call enableControls (this prevent the controls keep refresh
while the dataSet is scrolling), but is there any similar function in
JBuilder X?
my JDBTable connect to a large TableDataSet which contain > 10000 records, I
try to call TableDataSet.deleteAllRows() and find the machine hangs!! I
think the times is spent on continuous refreshing the display of JDBTable.
Thx!! |

Well, I don't know anything about java but in Delphi I never do what you
do ! I use an SQL command like this : "DELETE FROM db WHERE ..." and
most of the time, I create the command or query (dataset component)
needed directly in the code. I do a "free" when finished.
"deleteAllRows" is certainly not to be used with large tables.
