A timer will repeat execution at specified intervals.

The most important PEM for a Timer object are:

.Enabled: Set this to .T. if you want to use the Timer, or to .F. to disable it.

.Interval: For example, set this to 5000 to check every 5 seconds. (The time is specified in miliseconds.)

Timer() Event: Here you put the code that will get executed, for instance, every 5 seconds.


I think Çetin meant to use LLFF (fopen(), etc.) to check whether you can access the file.

I think this would be more or less like this:

* If you can obtain R/W access to a file, delete it
local lnMyFile
lnMyFile = fopen("MyExcelFile.xls", 2)
if lnMyFile > 0
  fclose(lnMyFile)
  erase MyExcelFile.xls
endif

Of course, instead of putting all the code into the Timer event, the Timer event can simply call a form method, or a procedure in another PRG.
