Windows - Timer - Service To Execute On The Half Hour And Top Of The Hour Marks

May 6, 2009

I wrote a VB.NET Windows Service, which works fine. I have only one issue with it. I want the service to execute on the half hour and top of the hour marks (e.g. 9:00, 9:30, 10:00, 10:30, 11:00, etc etc etc). I am using the following code:

Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.

[CODE]...

This code works, however, if the service starts at, say, 10:15, then it executes at 10:15, 10:45, 11:15, 11:45. How do I make it so it always executes on the 30 minute and top of the hour marks?

Trying To Create A 24-hour Timer

Jun 9, 2010

How would I go about creating a Timer that will fire an Event every 24 hours, 2 minutes? I know the Interval in ms is 86,420,000, but of course the Timer Interval will not go that high. Do I have to have a series of Timers to go off every minute until 24 hours is reached???

Convert A 24 Hour Time To 12 Hour In .net As Hh:mm AM/PM?

Jun 12, 2012

So let's say I have 1400, I want to convert it into 2:00PM I tried the following:Dim convertedTime As String = DateTime.ParseExact(theTime,"HHmm", Nothing)

And it would give me this: 6/12/2012 02:00:00 PM

I do not want the date part, neither do I need the seconds. All I need is 2:00PM

Using A Timer To Create A Delay?

Oct 15, 2009

I'm using Visual Basic 2008 Express Edition.I'm working on a class. At various points, I want to insert a delay between executions of the code. Nothing terribly large. Around 50-200 miliseconds. It doesn't seem like much, but it makes the program run better. I'll probably randomize the length of the delay later between those two marks. So basically the code would go...SomeFunction()timer delaySomeFuntion()I have the timer declared as

Private tmrTimer As TimerAnd each place I want to use it, I simply redeclare it. Or I might add it to the constructor of the class. Either way. Just thinking adding it to the class constructor would probably be a better idea.
tmrTimer =

[Code].....

End SubUnfortunately, I get the error "Handles clause requires a WithEvents variable defined in the containing type or one of its base types"Now remember, this is all contained in a class, so theoretically speaking I can simply move the class file from project to project and reuse it, without ever having to worry about how the class works. Reading through the Timer specifications, I probably need to do some cleanup on the timer after I use it. Am I correct in this?

Create A Delay Before The OK Button Is Enabled?

Nov 4, 2009

I have a Nag Screen that I am creating, and I am wanting to create a delay before the OK button is enabled allowing the user to proceed.

Is it better to use a Timer event or would a 'For I = 1 to 20000"
loop be the better option.

All this timer would do is Enable the OK button, thats all.

VS 2010 Create An Accurate Delay In VB2010?

May 19, 2012

I am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.

Time Delay - Make GUI Program To Delay Before The Next Command

Dec 21, 2009

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

SetLastWriteTime Is Off By 1 Hour?

Jan 16, 2009

I've written a console utility to set file date/time stamps to a specified date/time:

For Each FoundFile In My.Computer.FileSystem.GetFiles(FileSpecPath, FileIO.SearchOption.SearchTopLevelOnly, WildCards) FileInfo = My.Computer.FileSystem.GetFileInfo(FoundFile) System.IO.File.SetCreationTime(FileInfo.FullName, NewDate) System.IO.File.SetLastWriteTime(FileInfo.FullName, NewDate) System.IO.File.SetLastAccessTime(FileInfo.FullName, NewDate) Console.Write(FileInfo.Name + " " + NewDate)Next

When I go to a command prompt to check the results, the new date is correct, but the hour is off by 1 hour. Same when I check the times in Windows Explorer -- all three times are displayed to the same time, but exactly 1 hour earlier.The system date/time are correct (Vista) and we are not in DST.The files reside on a local drive (not a network share).The computer is not on a domain.

IO.File.GetLastAccessTime Is Off By One Hour

Jan 5, 2011

I'm working on a program that records date metadata from files, such as creation time, last modified time, etc. An old version of the program is written in VBA, and does something like this: [Code] Both functions are running on the same machine, checking the same file. I've also tried using the IO.FileInfo class with the same result. I've checked thousands of files and they are all off by one hour. The other date properties for creation time and last modified time are also off by one hour.

I forgot to mention in the original post, The computer's time zone is CST, and daylight savings time is currently not in effect. I've reproduced the problem on Windows 7 64 bit and Windows XP 32 bit.

everyone who suggested trying to calculate the desired date from UTC using the appropriate time zone offsets. At this time I'm deciding its not worth the risk to do so. For this particular business requirement, its much better to say the date value is not what you expected it to be because thats just the way the API works. If I attempt to "fix" this then I own it, and I'd rather not.

Just for kicks I tried using the good old Scripting.FileSystemObject via interop. It gives the expected results that agree with Windows Explorer, with about a 5x performance penalty compared to System.IO. If it turns out I must get dates that match what Windows Explorer has, I will bite the bullet and go this route. [Code]

Timer To Run 30 Minutes After The Hour?

Jul 15, 2010

Is it possible to configure the System.Timer to run say 30 minutes after every hour? I have searched google to figure this out but all it shows is how to set it where it goes off once an hour, if I launched the app at 2:45 then it would go off again at 3:45. I can forsee issues down the line with this approach where if it went off at a specified time it would not have that issue.

Normally i would use Scheduled Task for this however it doesn't give you the option for hourly just daily, perhaps i'm wrong about this.

Check Date And Hour Without Using Two Timers?

Right now i have this for the date:

Timer1.Stop()

PS (again): I thought about setting the Timer1 interval to 60000miliseconds, so that it would check the time everysingle step of the way (or maybe 10 minutes...), but I don't want the app to lag, so... How can i implement a Background Worker?
