VB6 -Access Timed scehduler..
Looking for assistance to write an application in VB 6 with Access 2000 (and/or 97).
The idea is that Access would have at least 2 tables... geo_section_date_time_file
The idea is to have a program that runs all the time and checks your system time and date. Depending on the time and date, the application would run a file (EXE/WAV/SQF/etc).. that has to be defaulted to certain file, but allow the user to change.. so say I opt in the database to open up Notepad at 7:00PM on June 2 from Section 3 facility in San Diego, CA .. then on such time (PST) on June 2 (every June 2)... Notepad should come up.. reason for Section and Location, is 1 for time (daylight savings or not) and section is say I want to kick off Notepad for Section 3 and MP3 file for Section 2 at the same time... I should be able too.
This app is to run all the time.. System Tray app would be the best. but I leave that to you.
The application should allow user to set the values in the database.. including file and file type... for this maybe a "wndows dialog box to select the file instead of typing in the name and location of the file.
The last and most important thing is that I need to learn from it.. so if you could comment the code.. I would appreciate that. Also, any references or components added, let me know if comments as well. Will learn and also use to help class learn.
If the code is tight, I will increase the points. I have another idea to build on this application, which is to make it an ASP project.. I hope to use the example and build on it with ASP to make it a web application for my class project.
Looking forward to your ideas...
Thanks.

I went to the site.. but the download requires a password.. which requires me to pay... plus if the owrk is done already... I can't request for the more detailed "commenting" allowing us to learn.
Does Vb have any compnoents that do the schedulers work or can you help me create something like that?

To create your own, you will need several things.
Scheduling Requirement Decisions
1) To what day level do you want to schedule events?
Daily? Day of week? Specific date?
2) What time granularity do you want to specify?
Do you want to specify exact times? Time windows?
3) If an event window is missed, what happens?
Run right away? Wait until next window?
Develop a notation for defining events as required above.
Write interpreter.
---
You'll need an event definition file to identify scheduled events. Something like an INI file or registry key would be handy. A section header (or key) would define the event name and values within the section would give the event parameters. For example:
[EventNameX]
COMMAND=<CommandToRun>
DATE=<DayList>
This specifies the days of the week on which the event is to be executed. <DayList> is a list of 3-character day name abbreviations separated by commas. The recognized abbreviations are: SUN, MON, TUE, WED, THU, FRI, SAT. Day name abbreviations may appear in any order and case is not important.
TIME=<TimeIntervalList>
This specifies one or more time intervals during which the event may be considered for execution (in conjunction with the day(s) specified on the DATE= command). Time intervals are separated by commas and have the format:
<StartHHMM>-<EndHHMM>
Each HHMM represents a 4-digit hour and minute combination based on a 24-hour clock.
To simplify the specification of events that are to be executed hourly, you may define a single window using '*' for both the beginning and end hour.
Note that there is no requirement that an event be completed within the specified interval. Rather, the interval is used only to specify a range of acceptable event begin times.
---
Next you'll need an event history log that records, at least, the most recent execution of any event. Something whose lines look like:
<EventName>=<LastExecution
---
At some regular interval, say once every minute:
* Load the event definition info
(opening it each time means changes take effect immediately)
* Look at each event to see if it qualifies for execution now.
* If it does, look in the event history log to see if the execution window it qualified for has been satisfied yet.
---
And that's pretty much it - a simple, not at all fancy event scheduler.

SNilsson - Is it possible to get code for this as the Schedule.zip file has a DLL which I am not allowed to register at my work pc.. which is where I need it. Is it possible for you to help with the code.. provide snippets or full code?
Cookre - could you elaborate? I am not sure what you were trying to do.. give direction or solution.. please clarify.. and if you can help with code .. that would be great.

That was a coarse outline for a scheduler I wrote for NetWare servers, but the idea can be implemented on any platform. Before starting any coding, however, you'll have to fully define WHAT it's supposed to do (the coding is just the HOW).
Recapping from above:
Scheduling Requirement Decisions
1) To what day level do you want to schedule events?
Daily? Day of week? Specific date?
Do you want scheduled events to repeat? If so, then such events would have start times
such as MONDAY/23:30, DAILY/16:45, FIRSTOFMONTH/10:00
Single executions might be defined like 2003/12/25-00:01
Other event times might be things like the third Tuesday of each month.
2) What time granularity do you want to specify?
Do you want to specify exact times? Time windows?
Some events may have to be scheduled for precise times, e.g., 23:56.
Others may be more lax - anytime between 23:00 and 23:55.
3) If an event window is missed, what happens?
Run right away? Wait until next window?
Despite all out desires, it may not be possible for something to start at 15:17. The box
may be busy doing something else that has control. That's the main reason for allowing
a start window instead of a hard, fixed time. In either case, however, one needs to specify
what the scheduler should do if an event window is missed.
Basicly, this means you need to define how you want to define a scheduled event. Implicit therein is also the question of interface - text file, GUI, whatever.

Sorry for the delay - I got sick and was in the hospital.
Given your time contraints, you should consider an off the shelf package.
I would estimate that writting this would take several weeks - and that's presuming a conversion of one that I have for NetWare written in Rexx.

If you can read Rexx, I edited down my scheduler to ~800 lines (removed the NetWare specific things).
Interested?

I don't know REXX... however if you think the code is easy to read or can be understood by someone who is a vb/asp programmer and who knows bits of Perl/Smalltalk...
again.. i don't know rexx..but am willing to try it.

How's it going?
Hope you get the points and an A for this Cookre (if the questioneer is still around that is) , you deserve it for all the work you put in to it.

Cookre.... Sorry for the delay.. I was pulled away for something else..
so I did not get a chance to try your code.. actually didn't get a chance to re-engineer it to VB code. Would still prefer this is VB code if you can.. this way, I can dwalk thru the code in debug mode and learn that way.. Debugging code is better than reading code (for me at least). From my end... you have got the points and an "A"... just hoping for VB code or more time on my hands to re-engineer the code.. that is why I am leaving this question open for a bit longer. Will give it a few more weeks and than award the points. Hope you don't mind!
SNilsson - Thank you for givign him credit.. and I definitely plan to give him the points and even if he can't help me with VB code.. he will get an A.. and if someone else comes by now and puts up VB code that works the way I need... Cookre will still get points..

Cookre.. .thank you for your help.. Sorry for delay.. I got busy with something else..
But here are you points and Grade A..
Also.. if you get a chance.. can you try to convert the code to VB?
Thanks.

As it turns out, I just started working on a service that will contain several of these event scheduling features. Alas, it'll be in C, but, if you're still interested, post something here around mid-February and I'll put up the C code.

Cookre...
Did you ever get to do the code that you spoke about?
I know it has been a long time.. but thought to try.

Sure did, but it's c#.NET.
I'll post it, but I've got to pull out some security specific things first.

This sound like a job for scheduler.
