C# - DateTime Issue In .net Regarding Automatic Scheduling?
May 23, 2012
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 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 ??
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 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 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 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 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.
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?
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.
I'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

Why is it so? The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.
datetime1 and datetime2now two fields are have data ( date )in table recordi want to update only datetime2 is an emptyi am using visual basic 2010 ( visual studio 2010
I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?
Assume the following program is started at 1:59:01 AM on 3/13/2011 in the United States. The first time Timer1 ticks what will be the value of the TimeSpan (ts)?
Public Class Form1 Private Sub Timer1_Tick(sender As System.Object, _ e As System.EventArgs) Handles Timer1.Tick
I'm trying to add the date and time of Today into a Sql-database-field that has the datetype datetime.
[Code]...
the msgbox gives me the following result: 29/01/2011 18:49:21 my sqlException gives me the following error: 102 - Incorrect syntax near '18'. Is it better that i set the datatype to char in my sql database? It's maybe a bit easier? When I do that, can I calculate with these date?
[code] "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated." [code]
i completed sending mail automatically. but i have an issue bothering me.i am using gmail as my smtp server and database as access.i am able to send mails but when i give a wrong address it is redirecting to my mail stating failure of delivery but i want that to be displyed on the console once i send the mail and also if net connection is not available i want it to show network connection is not available. here is the code so far

I am designing an Windows application in Vb.net. When ever I run the application it needs to check the current time and remind me some tasks which I have defined. In what way can I do this.
I want to send an automatic E-mail based on the date. If the current date is greater than 5 days than the current date field in the table then i need to send an E-mail to the designated person. I am using VS.NET2003/VB.NET/ASP.NET/SQL Sever 2000.
