Any ideas on how to speed up the table refresh rate?

[bthorp]

When adding rows to an existing table control, the screen refresh rate is extremely slow. I have had this issue with high and low speed computers. One solution, although not acceptable, was to hide the table while adding rows, then re-display the table. This sped up the add-row process, but of course caused the table to flash annoyingly. Any other suggestions? Thanks in advance.

To speed up table refreshing you should:
- add all rows at one call,
- to insert values use SetTableCellRangeVals function,
- before updating table set ATTR_VISIBLE to '0' when you finish set
ATTR_VISIBLE to 1
( don't call ProcessDrawEvents or ProcessSystemEvents while updating
table )

Using this three metodhs I speed up table refreshing (100 x 2000) more than
1000 times.

Setting ATTR_VISIBLE to '0' is great improvement, but unapplied for changing BG color of individual cells (not row or column). I need to change cells BG color in <1ms, and in some rare cases thing work, in other (only close and reopen LabView) not, they need almost 10 time more times.
