What is the best way to schedule task on VB.Net application? I have searched this forum and google but I still need some more comments.There are two ways that I've found so far:
Command Prompt By using AT or SCHTASKS command. My Windows 7 seems to recogonise both Command. May I know is there any significant different between this two command?
Timer By using Timer function, but I'm not sure whether is this a good method as it might slow down my program by constantly checking. May I know by using the above method, can I retrieve the scheduled task and display back in my program with ease?
I have an application that I need to automate where at a certain time each day, say 6pm, it will run a certain method(which is to check a database for key terms and then access the api to search for these terms). But there is also another process which is running all the time accessing the stream api so when the search is complete, it interrupts the stream and hands over the new terms.
Now I thought of adding the .exe file to windows task scheduler but not sure if that would work. The stream method run indefinitely and at 6pm each day another process needs to run. I thought of using the system.threading.task TaskFactory but when I include it, it shows taskfactory as undefined. ( I do have .net framework 4.0)If it launches using the task scheduler as 6pm with my code logic as follows:
I have a problem in detecting the 30 minutes interval in time scheduling like for example i have a combobox(starting_time) and combobox2(endtime) and I select there 9:30-10:00 it has 30 minutes I want to show a message box that I should be 1 hour.
is it guaranted that a task A started before TaskB will be completed before task B assuming the task do the same level of operatons?or in other words is there a chance that a task B will finish before tast A in the assumption that the task calls the same procedure?
I am having an issue where I need to implement a type of thread scheduling... I'm looking to implement a list of tasks, each with a set time that they need to execute, and after the time is up they will execute the respective code that goes with that task. I would use a timer based solution, however, I don't think that it would be very efficient. There will be a very large list of tasks, some of which need to be executed within seconds of being placed in the list.
this is the logic : smallest time + burst time = sum1 if the next arrival time is less than the sum1 then add the next burst time but if the next arrival time is greater than the sum1 then subtract the sum1 to the arrival time so you will get the difference1. after that the difference1 must be added to the sum1 then add the burst time. that is the cycle.
I am trying to write a vb.net code which would run evry moth and perform the following task:
it would retrieve three existing excel files from a folder ,perform excel based reporing modification on them and send them as emails to alist of users ids of whom are available in a fourth excel sheet(another folder)
i am not looking for thhe full code. but i donot know the syntax for
how to access excel files from within a vb code and morover perform operations on them.
secondly is it possible to scedule such a email sending application ??
I have a program that checks for the date and minute part of my job object. If these match then it triggers a particular job.
If jb.ScheduledStartTime.Value.ToString("MM/dd/yyyy mm") = Now().ToString("MM/dd/yyyy mm") Then 'Do some work here. End If
Issue:If I schedule different jobs during the day at different time interval then they just work fine. I mean they are triggered and in the above code they enter the loop when it matches the current format.
However, it doesn't work when the date changes at 12:00. Even though I have scheduled start time set to trigger at 9:00 AM in the morning it enters the loop exactly at 12:00 AM which is invalidating my logic leaving me confused.
I have 5 separate class libraries where each one of thses are consuming separate web services (the web services connects to a server, runs stored procedures and return data tables to the .dll).
My task is to sequentually run these 5 jobs unattended through a job scheduler. I am not really sure how to do this and what my options are.I was planning on creating a driver (a console application) that would call each .dll. If this is a acceptable way then I am not sure how to reference and call each .dll, could I use import, add a reference to the .dlls and instantiate a new class, make a setup project with dependancies etc.
I need references to how to schedule emails to notifiy users on a specific date in the month (each month).All the references I stumbled upon were in C#.I'm not that advanced to convert them properly to VB dot net.
I'm wondering if there is any scheduler control in Vb.Net -MS VS 2005- and if not I hope I can find a one - free - that I could use on my application...
how to implement scheduling tasks requirement in my application..
I have a question for the well versed among you. I have done some research, but didn't seem to find the exact answer I was looking for. So without further adieu.Given an event which needs to occur at a very specific time, whats the best and most predictable way or making that happen.
A: Use a worker thread, and threading.thread.sleep(TIME).
or B: Use System.Timers.Timer or System.Threading.Timer to execute in (TIME).
NOTE- I am fully aware that any of these will work. My question is in regards to priority of execution. How will a timer, which I can't figure out how to set a priority on, compare to a thread with a priority of Highest or even Real Time. Microseconds DO count in this instance.
I'm currently using SQL Server 2005 and I've created a business intelligence solution that has a "Package1" copying a table from a database to my local database. I tried executing this package/solution from my .Net IDE and it worked.
Later, I tried creating a job that will execute the package at the intervals of 1 hour per day using SQL Server Agent but when I get to the part where I select the type of job (under the "Job step property", I can't find the job type of "SQL Server Integration Services Package". I've been following this: http://www.mssqltips.com/tip.asp?tip=1180 tutorial but I can't execute my job probably because I'm using an incorrect job type.
I'm building an application that will need to run a specific functions at user defined times I need help with setting up the schedule part of the app. What I would ideally like to do is be able to set up an "event" which will occur at a specific time and date or at a specific time on specific days such as 9:00 Monday's Tuesday's Wednesday's and Saturday's.
I once saw in an app a control that allowed the user to choose when they wanted the Timer running. It looked something like this: And when the squares are green, for example Tuesday 3:15 AM - 4:15 AM, the timer would run during that time period. I'm curious as to what control will allow me to do something similar?
Anyone some advice how to schedule a task?At 19.00 hours I want to download new log-files, and restart the application.The download-part and the Application.Re(s)tart are not the issues here, but how do I tell my form that it is 19.00 hours?
How do you go about putting your app in the system tray or pinning to the task bar (as in Windows 7)?How do you become part of the right-click menu on the desktop or files - like you see various zip archive tools?

am doing my thesis entitled Automatic Exam Scheduling System. this works when button "GENERATE" is click. that would initialize the automatic assigning of proctors and rooms to classid.....plz help...i can't filter the conflicts of proctors and rooms since it is automated.
I am trying to make a random shift scheduling application for a rotating workforce that must satisfy the following basic requirements: 3 shifts (8 hours each) per day (Morning, Afternoon, Night), 2 workers per shift work a maximum of 7 consecutive days and rest a minimum 1 day. 9 Total workers separate in 5 supervisors and 4 operators, and 2 part time workers (1 supervisor and 1 operator) for covering the possible absences of 9 standard workers. Total days off are 8 days per month (normal sequence 2,2,4) and the vacation days are 22 per year. A basic rule is that the shift must cover from 2 supervisors, or 1 supervisor and 1 operator. 2 operators are forbidden.
im currently in the process of making a program that im going to release here. But i need a way to open Task Manager in VB 2008. Does anyone know a way to do it?
Even though I issue the commands, the EXCEL.exe still appear in the TASK MANAGER -> PROCESS after the Excel application is quit, closed and terminated.
How would i know when a thread is completed running it's task? I mean in background worker it has a completed event, but can i make something similar to that?
I want to run a series of .BAT files - but only have ONE RUNNING at a time. If I have two or three .BAT files I want them queued up so that only one runs - then the next - and so on. I could do this with other O/S task management tools. I was going to code my own methods - seeing if a .BAT was running - holding the others - etc. But the handshaking on this operation could be painful to test... I was hoping the SCHTASKS tool in windows would be my answer - but I'm not seeing options to do this.
My MDI parent form sizes itself so that the activity field (with the start button etc) doesnt show. This happens every now and then and I cant figure out why.
