Subject Using onCallback to Show Meter or Clock ticking with TIB_QUERY
Author R. S. Patil
Dear friends,

I am doing

select
*
from
Selectable_Proc(:Parma1, :Param2,....)

in a TIB_Query Components SQL property.

The SP is doing a bit longer processing before
any data is suspended.

Many times the user gets tired since while M/C
is processing there is no indication on the screen
only thing I could do was to turn the cursor to
different one but that's not sufficient. So I designed
a form to show a clock and a meter and I showed
it before I actually open the query.

for the query I have set CallbackInc to 1.
CallbackRefreshInt to 1000
and CallbackInitInt to 1000

In oncallback event I have put
Application.Processmessages

I ran application with BP set at above statement
I found execution do not reach to it and the
Clock as well the meter is standstill.

is anything else to be set ?
is there any demo application anywhere to explain
the timerbased callbacks even when there is no actual
fetching in progress ?


Best Regards
