Hopefully you may want not a windows program running, waiting for a timer during one month.

The best way is to isolate this functionalty in a separate console application and use the task scheduler of Windows to planify when, and under wich user, must be executed.

Be aware that this console application can not have any interactive screen or message, as is running in batch, and should end gently.

Hope this helps


i wan design a program that have a timer to execute certain code(like send sms) at certain period.
The period is select by user(daily,monthly,weekly) and user oso can execute this certain code manually at anytime when user wan.
who can provide the code that how to set this timer?


Dim WithEvents MyTimer as System.Timers.Timer ' to define the timer at module or class level
' inside de sub where you define when to fire the timer
Dim NumberOfSecondsToFiretheTimer As Double = 86400D ' One Day
MyTimer.Interval = NumberOfSecondsToFiretheTimer

To catch the event

Private Sub MyTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles MyTimer.Elapsed
'  do whatever you need
End Sub

i think, if your program running everyday, you can use timer event tick,then set interval, then the event you need just insert in that tick


if i wan the code execute at every monday(8am),how i nid to do?


Use the windows task scheduler
http://support.microsoft.com/kb/308569/en-us for XP

Also maybe you are interested on http://msdn.microsoft.com/en-us/library/aa383614(v=vs.85).aspx for the task scheduler API and http://msdn.microsoft.com/en-us/library/aa384006(v=vs.85).aspx showing examples about task scheduler API usage.

Hope this helps


may i got some code sample for this function?
it is bcoz i wan write the code in the program that i design so can generate a report every monday(8am).
it's urgent...


You could use a timer control that constantly checks the time and when the time matches 8:00 it will run your code. An example in vb.net is below. iIuse something similar to run a SQL Backup Utility I created.

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim time As Date = Date.Now
        Dim currhour As Integer
        Dim currminute As Integer
        Dim ReportHour As Integer
        Dim ReportMinute As Integer
        currhour = time.Hour
        currminute = time.Minute
        ReportHour = 08
        ReportMinute = 00
        If currhour = ReportHour AndAlso currminute = ReportMinute Then
        End If
    End Sub
