I Have a lot of numerical interval, never overlayed and not necessarly contigous, like this: 1-10, 11-56,90-134. how can I determine if a given interval, for example 45-90 is completely external to the other intervals?

View 10 RepliesI would like to know how to set the interval of QueryPerformanceCounter, and create subroutine with the tick event, that particular code is executed in the specified interval.I can do this in the Timer control, for example:
[code]...
But I want a more accurate timer.I read that QueryPerformanceCounter is more accurate but did not understand how to set the interval parameter and create a routine to perform a particular code.
I would like to run a code every 1 minute ,15 minute etc Is there any better way than following put in the timer control with time interval 1 sec. A c# solution is also ok.

I have this datetimepicker in my application. The user can select the time they want. I used a custom one and this is the code I used:
Code:
TimeFrom_dtp.CustomFormat = "HH:mm"
TimeTo_dtp.CustomFormat = "HH:mm"
I also have an array; a combobox and a variable called: TimeInterval. here is the code I use:
Code:
Dim ReadingFrequency(7) As Double
Dim TimeInterval As Integer
Private Sub CustomizeGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code]....
What I want is to change how much the datetimepicker increments, when you click the arrows, depending on the value that is entered in the combobox. For example, if the user has 2 hours in the combobox, the datetimepicker will increment by two hours and won't let the user change the minutes. If the user selects 15 minutes, the minutes will increment by 15 on the datetimepicker.
What would be the best way to run a subroutine over and over again every X seconds. I want to avoid creating an infinite while loop to do this because this sub needs to be called repeatedly while the rest of the program is still active and responding.

So, I have two timers. 1 Timer is set with an interval of 1000 (milliseconds), therefore it goes off every 1 second. For some reason, when I set the interval on the same timer to 1, it goes off 100 times every second. Shouldn't it go off 1000 times every second? What's going on?
View 4 RepliesHow can I get a timer to run one interval,one interval only, and stop? Until now I have only used timers to keep running until I say to stop. Also I need a timer that will start at the beginning of, and run until any given process is completed.Upon completion it should shut off and tell me how long the process took. Kinda like a stop watch with a Stop / Start "Trigger".

View 12 RepliesI need to check my field in format ddMMyyyy(ex 12/03/1990) whether in interval of two dates that user picks from two date picker controls. Two date pickers are in custom format dd/MM. It does not matter for me if its between particular years. I need just to know if given Birthday belongs to interval taken from screen. Each datepicker gives values dd/mm/yyyy.

I am trying to write a simple code that will essentially change the background oclor of a form from say red to green, like every five seconds.(Actually, it will be green 4 and red 6 seconds).
