Hi Antonio

I changed to this

oDb:CreateIndex(alltrim(oIndex:datafile),alltrim(oIndex:tagname),alltrim(oIndex:key),{||if(!empty(oIndex:cond),alltrim(oIndex:cond),oIndex:cond)})

the indexes are created but when I use an index which has a condition it does not work.

Regards

Colin

Hi James Thanks for the advice. I look forward to future discussions. My code consists of a small module that instantiates the required objects, calls for user logon (via a USER_Class) launches a main window with a menu has a couple of utility functions but all the rest is done via objects that inte...

Dear Dale,

What does it mean "CRC of Datafile"? and
How do I check it (Which function)?

Thanks,
Dutch

100 means 0.1 seconds. I would use 1000 (1 second) to reduce the CPU usage.

OK - I think I am getting very clever. I have defined a timer with an interval of 100 that checks the CRC of the datafile and only if the CRC has changed will it refresh the listbox browse. This works as any changes made on workstation 1 immediately update on the display of workstation ...
