Anyone use the timer feature of RichCopy? I have a job that works fine when I manually start the job. However, when I schedule the job and click run, the app appears to be waiting for the scheduled time to elapse yet never fires. Interesting enough when I stop the job the copy starts.
Anyone have any experience with using RichCopy timer?

Try created a batch file with command line options. Then use windows scheduler to launch the batch.
OMBG (Bill Gates) You need to read and get security policy and the respect it has to place on a hierarchy of upstream objects and credentials. Well that's the MS answer and attitude...
The reality is if you are working with server OSs you need to understand their security & policy frameworks, and how to debug them :). If your process loses the necessary file permissions or rights (2 different things) you should ask: "Hot damn, why didn't I fix that in the config/setup". People that blast the vendor/project (or even ####&$! MS) are just blinding themselves to the solution/s.
In most cases this kind of issue is due to Windows' AD removing the rights of a Local administrator User to run a scheduled task. It is a common security setting in corporate networks (implemented with glee by Domain Admins to upset developers) though it is really a default setting these days. It happens because the machine updates against an upstream policy (after you've scheduled a task) and decides that all of a sudden it won't trust you to run it (even though previously it let you set it up). In a perfect world it wouldn't let you set it up in the first place, but that isn't the way policy applies in Windows... (####&$! MS). LOL
Wow it only took 5 months to get an answer! (but here they are for the next person at least!)

I'm wondering is there a way to recognize the OfflineComamd is being executed or internal flag or something to represent this command has been passed or mark it has been executed successfully. I have issue in recognizing the command is passed or not with unstable internet. I keep retrieve the records from database and comparing each and every time to see this has been passed or not. But due to the flow of my application, I'm finding it very difficult to avoid duplicates.IS there any automatic process to make sure commands executed automatically or something else?
2nd question, I can use UITimer to check isOffline() to make sure internet is connected or not on the forms. Is there something equivalent on server page or where queries is written to see internet is disconnected or not. When the control moved to queries and internet is disconnected I see the dialog open from form page being frozen for unlimited time and will not end. I have to close and re-open the app to continue the synchronization process.At the same time I cannot set a timeout for dialog because I'm not sure how long it will take the complete the Synchronization process. Please advise.
Extending on the same topic but I have created a new issue just to give more clarity on my questions.
executeOfflineCommand skips a command while executing from storage on Android
There is no way to know if a connection will stay stable as it requires knowledge of the future. You can work like transaction services do where the server side processes an offline command as a transaction using the approach of 2-phase commit.
In this approach you have an algorithm similar to this:
Client sends command to server
Server returns a special unique ID for the command
Client asks server to perform the unique id
Server acknowledges that the command was performed
If the first 2 stages didn't complete you just do that again. The worst thing that could happen is some orphan commands on the server.
If the 3rd option didn't complete you just do it again. The server knows whether it processed the command and will just acknowledge it if it was already processed.
I have a web scraping job that needs to be executed each evening. Our company has a virtual machine with the "Windows Task Manager" application installed. So, I created a new task (i.e., an entry in task manager) to run every evening at 3 a.m.
Initially, the process did exactly as expected: it fetched the data and inserted them into our database. A few nights later, the website we were scraping from kept shutting down for maintenance, so I went into Task Manager, changed the time setting to start at 10:30 pm instead of 3:00 a.m., and waited until the next morning.
The script executed completely with no exception issues- but nothing was entered into the database! The task manager even said that the script ran completely, and it even took the usual amount of time to run, but alas, no new rows.
One might posit that there was no new data to fetch. However, When I execute the script manually from the command line (and kept the start date/end date the same), the script uploaded the usual ~10,000 rows into the database. So there is data- but it only gets written to the database when we launch the script manually during the day, and not when scheduled in the evening.
Does anyone know a potential reason as to why this happens?
Thank you in advance.
Edited to add:
I understand that this question might sound a little ridiculous, especially since from the surface, there doesn't seem to be a lone factor in determining the issue. If I could provide any further background information into the issue, feel free to ask.
We have a Practice Management system that is about 15 years old. I've been working on it for about 12, and I've never encountered this problem until just recently, and we can't figure it out.
It is written in VB6 which uses ADO/JET to access an Access .mdb file on the network. The application opens the connection when it starts, keeps it open while it's open, and closes it when it exits. It does a LOT of stuff with the DB - the system deals with Patient Accounts, Charges, Payments, Scheduling Appointments, and about a million other things. We have dozens of clients that use this program, each with their own DB and most of them 'offsite', where they have their own server, some number of workstations, between 1 and 20 users, pounding away at the system 24 hours a day, 7 days a week, and except for the occasional DB field bug or having to compact/repair DBs, it's pretty stable.
About 3 weeks ago, we started seeing a problem that we hadn't seen before.
We have an 'in-house' system setup for us to use: the DB is on our Server which houses maybe 10 other DBs, and only a couple of people connect in to this system.
We started noticing that if someone logged into the system, went straight to our Scheduler screen, and then sat idle for about 5-10 minutes, they might get "Disk or Network Error", or "Cannot find the input table or query X on database Y".
What's strange is that it SEEMS to happen only when 2 or more people are logged into that DB from different computers, and then one of them will get the error (Randomly?) but the other 2 users will be fine.
There is a Timer on the 'main' MDI Parent form of the system which wakes up about ever minute (there are some things which will change the interval to a shorter interval, and there are some things which disable the timer, but we don't think either of them are happening in this situation). It performs a pretty basic SQL Query on the DB: SELECT loggedin FROM Users WHERE UserId = 'DBUPDATER' THIS is the SQL Query that seems to be ALWAYS triggering one of those errors.
There is also a timer that runs about every 2 minutes while a user is logged in to check for emails and a few other things that would be running during this time.
And since they are on the Scheduler screen, there's a timer on there that runs every 30s or so which will check the DB to see if any changes to the scheduler have been made to see if it needs to refresh the screen or not.
There are some other strange things:
The DB and the Users table seem to be perfectly fine. When the person who gets the error logged into the system - usually only 5 minutes earlier - the system HAD to look at the Users table to mark them as Logged in, and I'm almost 100% sure that the query that it's dying on had been run at least once - probably 4-5 times before it dies.
Once a user gets this error, if they leave the Error's MessageBox on the screen (not quit the .exe), if they try to access that DB file in any way, they get "Disk or Network error" - this includes if they try to open that DB in Access. HOWEVER, they can still get to the Network just fine, and even open up other mdb files IN THE SAME FOLDER as the one they can't open. OTHER PEOPLE on other computers can open that mdb without any errors. Once the user acknowledges the Error, and allow the exe to close, they can open that DB file again just fine.
I'm told that this is not in anyway a Network issue. Our IT guy says he's run pings and traces and all sorts of tests to ensure that the network connection is not getting dropped.
I've also run some things on the DB to make sure it's not corrupted and it seems to be fine - and we get it to happen on other DBs.
If anyone has seen anything like this and knows a possible fix, I would greatly appreciate it! Thanks!
New Information (9/5/13 - 10:30am)
We noticed that at the same time we get this error, in the errorlog on the computer that gets the error is a Warning Event that says:
{Delayed Write Failed} Windows was unable to save all the data for the file \MEDTECHSERVER\MEDTECH DATA\VB\SCHEDTEST2\MEDTECH.MDB; the data has been lost. This error was returned by the server on which the file exists. Please try to save this file elsewhere.
I have several HTTP callouts that are in a schedulable and set to run ever hour or so. After I deployed the app on the app exchange and had a salesforce user download it to test, it seems the jobs are not executing.
I can see the jobs are being scheduled to run accordingly however the database never seems to change. Is there any reason this could be happening or is there a good chance the flaw lies in my code?
I was thinking that it could be permissions however I am not sure (its the first app I am deploying).
Check if the organisation of your end user has added your endpoint to "remote site settings" in the setup. By endpoint I mean an address that's being called (or just the domain).
If the class is scheduled properly (which I believe would be a manual action, not just something that magically happens after installation... unless you've used a post-install script?) you could also examine Setup -> Apex Jobs and check if there are any errors. If I'm right, there will be an error about callout not allowed due to remote site settings. If not - there's still a chance you'll see something that will make you think. For example batch job has executed successfully but there were 0 iterations -> problem?
Last but not least - you can always try the debug logs :) Enable them in Setup (or open the developer console), fire the scheduled class's execute() manually and observe the results? How to fire it manually? Sth like this pasted to "execute anonymous":
MySchedulableClass sched = new MySchedubulableClass();
sched.execute(null);
Or - since you know what's inside the scheduled class - simply experiment.
Please note that if the updates you might be performing somehow violate for example validation rules your client has - yes, the database will be unchanged. But in such case you should still be able to see failures in Setup -> Apex Jobs.
I've got a winforms app that I developed to do batch processing on tens of thousands of students, now we're trying to run it nightly as a scheduled task.
I personally find it useful to be able to login to the box and see how it's processing by looking at the GUI, though the standard way it to convert it into a commandline app.(which radically limits the amount of screen realestae I can use for loggin messages)
Can I run the app as a schedueld task, the IT Guy whos scheduling says it's not running because it's a winform app. Are there any tricks needed to get it to run well, or am I forced to rewrite it as a commandline app with it's 80 char width limit.
Basicaly I just echo the log file to the screen in realtime to make debugging issues easier. So the gui is output only.
Its' running as the currently loggedin user, but the issue is that it does not run if the user is not currently logged in on the box,so when we leave for the night it fails to run.
Thanks,
Eric-
You need to make sure it is running as the currently logged in account. If it runs as 'system' I don't think it will show up correctly.
I have one of these myself... and despise it. It only exists because I haven't had a chance to rewrite it into a proper service. Don't forget there are more ways to log than just outputting to the console. ;)
