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

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?

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.

Program Runs Slowly After About An Hour And A Half Or So

Jun 29, 2011

I created a program that has 11 threads running simultaneously.Each thread runs a stopwatch and measures the amount of time that passes between the Start and Stop.There is no code between the start and stop, so most often, the result is 0 milliseconds.I noticed that INITIALLY, after a few minutes, the program would slow and the output to the RichTextBox would become disjointed.So, every two minutes, I have a timer execute and end the threads and restart them all.This seemed to help, however, after about an hour and a half, the program becomes more sluggish, evident in the stopwatches recording more instances over 0 milliseconds.Does this have to do with 'garbage collection' and is that even possible in VB .NET (I thought C only had that), or perhaps memory management?

User Is Waiting Or Staring At The Hour-glass?

Nov 2, 2011

This is my follow up question to my earlier topic about Memory management.Now I believe I have good code that gets me the results I want.  The main application form has a Label field which tells the user to wait with message "Getting the data from the AD Database......".  I am noticing that the "Wait" message is up for too long.  However, once I get the data, it is processed fast and loaded into the DataGridView.

I would like the user to have a better feedback than the stardard "Wait" cursor. Is there a better way to show how much data (records) were fetched during the data aquisition phase and present it to the user?  This would allow the user to guess how much longer he has to wait to complete the data fetching.
