The purpose of this article is to help to .net developer to add custom scheduling
task to windows scheduler using c#.net.
Let's write a console application to perform a schedule job.to this you need , open
visual studio and select new Project menu , then select console application from
list of template in window.look figure to more clear.
Lets write simple operation within the program.cs file.
Within the job performer application have followings lines of code to create a simple
text file write date and time into the file.
Code:
static void Main(string[] args)
{
using (FileStream stream=new FileStream(@"c:\schedulejobCreated.txt",FileMode.Append))
{
using (StreamWriter writer=new StreamWriter(stream))
{
writer.Write("Date and time" + DateTime.Now.ToLongDateString() + "-" + DateTime.Now.ToLongTimeString());
}
}
}
Next step we need create a GUI for configure schedule with Windows scheduler.that
like be followings,
Here we need supply job name , that's mandatory field user name and password also
you must supply to add task on the widows scheduler.
Lets say now have to schedule our SchedulerPeformer to a weekly job to create file
in your local drive. to that you need write code like followings.
Note:here I'm suing a custom lib for access windows scheduler on the Machine.
when user supply all value on the GUI click Configure button to save.Lets say you
are going configure like this GUI showing
The button click event code like be
private void btnConfigure_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(txtName.Text))
{
MessageBox.Show("Please enter task name");
return;
}
else if (cmbtaskTypes.SelectedIndex < 0)
{
MessageBox.Show("Please select the schedule task type");
return;
}
else if (string.IsNullOrEmpty(txttime.Text))
{
MessageBox.Show("Please enter time to begin task");
return;
}
short hour = short.Parse(txttime.Text.Substring(0, 2));
short minute = short.Parse(txttime.Text.Substring(3, 2));
using (ScheduledTasks tasks = new ScheduledTasks())
{
Task task = null;
if (tasks.OpenTask(txtName.Text.TrimEnd()) == null)
{
task = tasks.CreateTask(txtName.Text.TrimEnd());
}
// Fill in the program info
task.ApplicationName = "ScheduleJobPerformer.exe";// here you need give full path of the your exe
task.Comment = "Create file on the disk";
// Set the account under which the task should run.
task.SetAccountInformation(txtUserName.Text, txtpwd.Text.ToString());
// Declare that the system must have been idle for ten minutes before
// the task will start
task.IdleWaitMinutes = 10;
// Allow the task to run for no more than 2 hours, 30 minutes.
task.MaxRunTime = new TimeSpan(12, 0, 0);
// Set priority to only run when system is idle.
task.Priority = System.Diagnostics.ProcessPriorityClass.Idle;
if (cmbtaskTypes.SelectedText.Equals("Weekly"))
{
if (chkmon.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Monday));
}
if (chktus.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Tuesday));
}
if (chkwed.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Wednesday));
}
if (chktur.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Thursday));
}
if (chkfri.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Friday));
}
if (chksat.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Saturday));
}
if (chksun.Checked == true)
{
task.Triggers.Add(new WeeklyTrigger(hour, minute, DaysOfTheWeek.Sunday));
}
}
else if (cmbtaskTypes.SelectedText.Equals("Daily"))
{
task.Triggers.Add(new DailyTrigger(hour, minute, 1));
}
else
{
int []days =new int[] {4,12,15,20};
task.Triggers.Add(new MonthlyTrigger(hour, minute,days));
}
// Save the changes that have been made.
task.Save();
// Close the task to release its COM resources.
task.Close();
}
}
Note:You need add using statement on the top of the code file
using TaskScheduler;
when you clicked and configured, just verify its was create on on the windows scheduler.just
go to the control panel, the select schedule tasks.
The look there task name as FileCreator,then double click on that.its look like followings,
Look nice everything fine. i hope this helpful to who are create schedule job with
windows scheduler.
