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
I have 2 datetimepickers. I want one to display the current time and the other to display the time one hour ago: So far I can getb them both to display the current time:
Code:
Dim TimeInterval As Integer = 60
Private Sub SustomizeGraph_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TimeTo_dtp.CustomFormat = "HH:00"
[code]....
vb Label3.Text = Format(Now, "mm:hh")
That is my issue. It's giving me 24 hour time, and I want 12 hour time, with out showing AM or PM.
I have an string and I want to convert it into time format just like this. [code]

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?

This seems so simple, but I can't get the answer. I need to get the current time in an hh:mm:ss or sss military format. By military format, I mean that if it is past noon, the hour is the PM time plus 12 (1 PM is 13, 5 PM is 17). I found this bit of code:
[Code]...
It returns the hour in AM/PM format. That is, if it is 4 PM, it returns 04 rather than 16). I can't find documentation on the hh:mm:ss mask. In fact I can't find a simple discussion on how to make the time of day property return time in various formats. After 3 hours of futzing around,
This code blow give me this error:
Conversion failed when converting date and/or time from character string.
Code
sqlstr = "select excute_main.*,cycle_main.cust_id,customers.name2 from excute_main,customers,cycle_main where date2 between '" & Format(MaskedTextBox1.Text, "MM-dd-yyyy") & "' and '" & Format(MaskedTextBox2.Text, "MM-dd-yyyy") & "' and excute_main.main_id=cycle_main.id and cycle_main.cust_id=customers.id"
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
I am trying to create what I am sure is a simple program to add hours to convert UTC time. I want to type in a UTC time and have it convert for every state in Australia. [Code] Now that works fine however when the conversion goes past "midnight" it then shows the date and time. I have tried about 50 different things but cannot get it to remove the date when the converted time passes midnight. [Code] The string was not recognized as a valid DateTime. There is an unknown word starting at index 18.
