I was wondering if it's possible to add seconds to a clock in vb.net. I mean lt's say I have a label and I assign it to DateTime.Now(), how would I show/display the time with the seconds "ticking"?

I am trying to add 60 seconds to the current time (purchase time) but would my method of System.DateTime.Now.ToString("HH:mm:ss") + 60 add 60 seconds to the current time ?
I have a masked textbox (dd/mm/yyyy hh:mm:ss) and a textbox (hh:mm:ss). I want to calculate the difference of them both and put the result in an other masked textbox (dd/mm/yyyy hh:mm:ss).e.g.13/11/1979 10:00:00 - 15:00:00 = 12/11/1979 19:00:00..I already tried Date.FromOADate(CDbl(dec_time) , where dec_time stands for the difference between first and second part of the equation.

View 1 RepliesI tried Console.WriteLine(Cstr(DateTime.Now)) and it shows the time down to the seconds, ie, "5/26/2009 5:17:02 PM" But, is there an option to show the current time more detailed than seconds, ie, "5/26/2009 5:17:02.xxx PM"
View 2 RepliesBasically, my app has the main form and a windows form "splash". Let me explain, this "Splash" is a WINDOWS FORM, not a splash form; its just named splash because I want to use it for that reason.In my project settings, my main form is my startup, and the splash form is my splash. This splash form has been coded on a timer for 10 seconds, but when I set the splash form as the splash setting, the form shows up for 1 second and goes to the main form.What I need is to edit the splash setting time from 1 second to x# seconds (preferebly 10)
View 2 RepliesI am trying to make a simple program to convert time given in seconds to hh:mm:ss format. But for some particular input values it produces incorrect time format. This is what I have tried :
Public Class Form1

Works When the Input Value is 30:
Does not Work When the Input Value is 31:

I am writing a program and have run into an issue. The program requires a conversion of time (e.g. hours,minutes,seconds) to a hexadecimal value of no more than 4 bytes (e.g. FFFF). I have no idea how this is done. Can anyone point me to a tutorial or give a quick explanation. Sample code would be great as well.

I am trying to make a program in visual basic 2010 where the user enters hours minutes and seconds into text boxes and then the program will count down from that until its equal to 0 when a msgbox appears and says its finished. I was converting hour entered, minutes entered, and seconds entered all into seconds and then having a timer subtract 1 from that until its equal to 0. But the problem I'm having is that I want to display the hours, minutes and seconds left in a label to the user in a format of: "hours: 0 minutes: 23 seconds :42" but how to display it in this format.
View 2 RepliesI have an application where event driven events are already detected. Each time an even is detected I increment a counter.I would like to add the following functionality:
1.) I would like to create a time stamp each time an event is detected and store them in some kind of data structure.
2.) I would like to count how many events are being stored (or in essence count how many events have occurred in the past 10 seconds, not once but continuously).
3.) I would then like to discard of any events older than 10 seconds note events are interrupt driven and can occur more frequently than once a second, but updating my count of how many events have occurred in the past 10 seconds can be done as infrequently as say once a second.

View 1 RepliesI 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 would be very grateful of any insight/resolution of the following issue I need to overcome.Using VS/VB2008 Pro/SQLExpress - all running on XP, I am building a WinForm Application (a Quotation application for Landscape Designers).48 Bound controls on my form work perfectly with DataSet and Tables when Updating any user changes to controls on the form to variables that determine price/cost of work being quoted for - providing the DataSet has already got values in it; Delete also works fine. However, although the "AddNew" (on form's BindingNavigator) works, it takes 30 - 35 seconds to add a new row. Table contains 10 rows and 45 columns. This is unacceptable and despite most of this afternoon reading forums, searches etc, I have failed to find a solution to an issue that I cannot believe appears to be so infrequent. Clearly, it is something I am doing or not doing.
I have searched via Google, crawled over MSDN pages, read/searched some of the standard textbooks on VB 2008 and looked (again) at Beth Massi's Data-related Forms over Data video series. I have re-checked the properties for the TableAdapter/Manager on my Form. I have used the wizards to create the necessary Select etc clauses. All runs as required except when user needs to add a new row (aka "New Quotation")

View 4 RepliesI have intger that represent time, but are not time values. So I have a MIN as int = 5 and SEC as int = 25. And I want to subtract 30 from SEC.
In normal math I would get -5. But this is time, so my MIN should be 4 and SEC be 55. Is there a formula for this already?

I have a windows form application that will open other forms, but will only display the forms for a few seconds (user configurable). I would normally do something like threading.thread.sleep(n), however when doing this the forms controls do not load only the white background shows, and I have also been reading that this isnt the best practice for what I am after as user input will not be actioned until the thread wakes up.
I have come across people using System.Timers.Timer(n), but I am struggling to get this to work for me, the form will only open and close straight away (you can only see a flash as the form opens then closes).
The code that I am using is:
Private Shared tmr As New System.Timers.Timer
aForm.Show()
tmr = New System.Timers.Timer(aSleep * 60 * 60)
[Code].....
This is all contained within a Private sub that passes the form and the defined run time.
My intention is to have the main application running from the task bar, which then calls one of the forms that will display for a defined period of time, close the form, then call another one of the forms.
Is any able to point me in the right direction for why the form opens then closes without seeing through the defined run time (I have been testing with 10 seconds), or is there a better way of doing what I am seeking?
