WD24. hFilter.

Hi all,

I'm using hFilter to show special content in a table. Is there a way to catch an empty filter, so the filter doesn't give any values back.
I use hfFilter together with TableDisplay(Table,TaInit).

Best regards,

AadG

Hi AadG,

just use the filter to filter for a value that will never ever appear in that database item.

Kind regards,

Hi Guenter,

I don't know exactly what you mean. What I want is, that when a searched value is not found during the filter, I get a message "Value not found".
and not an empty table.

Thanks for your reply.

Hi, you'd have to add an

IF HReadseekFirst(YourFile, YourKey, YourFilterValue) THEN
HFilter(.....
ELSE
Info("Filter value can't be found in file!")
END

Kind regards,
