Efficient timers in Net Express or Object COBOL

Hi

I've been looking at the threads here and haven't found a clear answer
to the question:

Is there or is it possible to implement an efficient timer control,
class or algorithim in either of these products?

By efficient I mean something that does not use a hard loop and will
not eat CPU cycles. In most of the Microsoft family of Visual products
visual timer controls are part of the product offering and these seem
to be designed using system api's rather than loops so that overall
performance is not degraded.

Does Micro Focus have anything that's equivalent?

Thanks

Elliot

If you are on Windows and you feel up to using the Windows' API directly,
the timer objects created by the CreateTimer and CeateWaitableTimer
functions are what the MS-Visual Anything 'native' functions use (see these
functions in your Windows' API reference).

Both utilize the normal thread-switching alogrithms of the Windows Operating
system, essentially checking timer status at the same time it is checking
that another thread may run.. that is, there is no "looping" other than what
the operating system does anyway to parcel out CPU time amongst all users.

No, I don't know how to implement these using the Microfocus / Net Express
product(s), but I'm sure you can make WinAPI calls, so there simply must be
a way to do it; perhaps someone here can point you in the right direction.

(FWIW, IMNSHO Microsoft Visual Anything is designed for those less capable
than the audience here).

Thanks Michael

Are you aware of any example code for doing API calls in general in Net
Exress?

Nah.

I ain't done no COBOL for more than five years, and all that was procedural
"batch-type" or "console display-accept" type code.

But if you can figure out how to call a standard DLL you can do it, because
that's all the WinAPIs are, a bunch (make that, "a **WHOLE** bunch) of
functions in a bunch of DLLs.

That said, if you are hooking into window procedures, then you may have to
watch out for 'compiler-specific' quirks... much as you have to do with
Microsoft Visual Anything.

(Adding a little shameless self-promotion)...let's say find what you need
for calling a function in a DLL, but are just not comfortable using all the
system objects... you could always contract with someone who does understand
those things, who could create for you a DLL with all the functions you need
using the syntax you want.... someone like, well, myself.

Hi Elliot,

If you look under the Micro Focus SupportLine site at
http://supportline.microfocus.com/e...mp.asp#Win32API ,
you will find a variety of examples of calling Windows APIs. (You may need
to register/login to access this page).

Hope this helps.

Thanks for the help everyone.

I think I'm going to run my COBOL program from an external scheduler.
Why reinvent the wheel?

Because Real Men don't need no stinkin' external schedulers.

Oh well I guess I'll just have to email you a nasty reply in hex ...

How nasty can you get restricted to the letters A, B, C, D, E and F?

(oh-oh, that was asking for it, wasn't it?)

Is that the same as sending a hex by email?
