Bit stuck on this one, have seen alot about how to do it just cant seem to get it right. I want to have 2 text boxes with times in them.. at the moment i have them on click events then it just runs a Now for the time and fills the boxes from the system time. But then i want the 3rd box to find the elapsed time from the 2 times in the previous boxes but i just cant seem to figure it out

View 1 RepliesI have VS 2008 and wow is it different from the old VB I used about 10 yrs ago! What I am trying to learn is how to create an ap that has a window that displays elapsed time like a stopwatch. Then I would like to be able to click a button to pause that time and start another timer, and then have yet another button to reset all. I have the form designed using a RichTextBox but am not sure that is the best way to display the times.

I am trying to calculate a total cost from an elapsed time. Dependant on how long the time is, this will calculate the total cost. It has to be 3 to every hour. The elapsed time is displayed in label6 in "hh:MM:ss" format and the total cost needs to be displayed in label8.

View 1 Replieshow to get the time difference between 2 date & times Where
from_time falls >= 22:00 of the From_date & the to_time falls <= 06 of the To_Date
for example:
From_Date = 01/01/2011 20:00 ' Where Work Started
To_Date = 02/01/2011 08:00 'Where Work Ended
Time_Covered_Between_22TO06_As_Night = 22:00 to 06:00 is 08:00 hrs How to equate it?
I have one text box that contains a value for the "Start Time" and another text box that contains a value for the "End Time."Both of the values are expressed in a format for military time (i.e. 1200, 1300, 1430, etc.).When the "End Time" text box loses focus, I would like the "Elasped Time" (expressed in minutes) to appear in a third text box.Seems easy enough...right?Well the problem I'm having is since the first two numbers in military time are base 24 and the last two numbers are base 60, a standard calculation subtracting the "End Time" from the "Start Time" does not yield an accurate result.
View 3 RepliesIm using the express edition of VB.Net to do my project. I have several threads in my program which run fine. However, im stuck at this problem. I have a button in my form, which if I click I will call ThreadA (works fine), If i keep it pressed for more than 2 sec i need to call ThreadB (doesnt work), and if the time is more than 2 min, i need to stop and send a msg to the user. I have tried the timer to calculate the elapsed time, so the tick function would call the thread. BUT this doesnt work... Im not sure what do to.
View 2 Repliesdisplay a Decimal (or double) to elapsed time [h]:mm:ss (hours:minutes:seconds)using vb.net?
example:
if you were to type "1.34666666666667" into a cell in Excel then choose Custom Format [h]:mm:ss The result is an elapsed time of "32:19:12". Using the OADate function only runs on a 24 hour clock so this does not work for longer durations unfortunately...

I have a very simple StopWatch application in Silverlight. I have the following private properties in my MainPage class: _StopPressed (bool), _TimeStart, _Elapsed (string). I also have a "Start" and "Stop" button. The "Start" button calls a method called UpdateTime that constantly updates _ElapsedTime until _StopPressed is true. When I originally wrote it, UpdateTime would block the UI so I couldn't press the Stop button, so I updated my code to use System.Threading.ThreadPool.QueueUserWorkItem with my UpdateTime method so that it updates _Elapsed on a background thread. That works great at updating the value.However, if I try to set the .Text value of my TextBlock from within UpdateTime(), I get an UnauthorizedAccessException that has to do with one thread accessing the data in another thread.What do I need to do to avoid getting this exception and appropriately update the UI without blocking it?
View 1 RepliesHow long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -

I'm creating a multi-threaded application (although it is not at the moment) which will be connecting to a large number of sockets. I've noticed when a connection cannot be made the connect timeout is rather large, so I am trying to make my own. Here is what I have come up with...
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CreateSockets(2)
AssignSockets(0, "192.168.31.2", 80, False, False) 'shouldn't connect

Looking at the timeoutOccured() sub, you can see I'm unsure of how to specify which index to set. Efficiency is important since this will be housing a lot of connections at once. Something else that just came to mind, would .theTimer.Stop reset the tick value on the timer?

Basically, it's a booking system and in the database I have two datetime fields.
CODE:
As you'll see, these particular records represent seperate bookings, each taking an hour each. My question is what would be the best way of viewing what times I have available (taking into consideration the data in the database)? After 11:00, the room is free, so I'd like to return 11:00-17:00 is available.

I am having an asp.net page which i was showing as a pop up using Nyromodel. the page contains
4 div which is showing as Tabs (using Jquery Tabs). 4 Repeater . Each repeater I am having a custom control and I am setting the value from db by setting the datasource to repeater. (This query may have 300-500 rows). 1 infragistics UltraWebGrid. I add selected values to the grid.
So the problem is it is taking too much time to render if I perform any operation in that UI. I logged the sp execution time, then I found that SP i taking only 2-3 seconds. But the control will render completely after 30-40 seconds. So sp execution time alone is not enough to satisfy the my lead. how to analysis the time of rendering the control.
I need some help working out the logic when retrieving specific times from a userform I have created. In my userform, users are required to input a start and a end time in 24 hour time format. I am struggling to work out how best to analyze the selected times in order to multiply them by a set of rates, the rates are quite simple:
DayHours rate (day time is between 07:00 - 22:59)
NightHours rate (night time is between 23:00 - 06:59)
I cannot workout the logic to ascertain how many hours have been selected for which rate in an elegant manner, my best attempts so far are clunky and not quite there.
Is it just me or is it so that a DateTimePicker can only be used for entering dates or times but not both?

View 4 RepliesBasically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.
Is there a better (and faster) way to find out the last modified date/time for an entire drive (or folder) without scanning each file and folder individually to find the latest modified date?

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?
I'm wondering how I would go about retrieving all the times between Two Times. I have 4 Textboxes.
1: Hour 1
2: Minute 1
Between
3: Hour 2
4: Minute 2

15:34
16:12
18:08
09:17
10:26
21:05
21:35
21:45
21:50
22:18
23:10
My
Dim Time1 As String
Dim Time2 As String
Time1 = (txt1H.Text & ":" & txt1M.Text)
Time2 = (txt2H.Text & ":" & txt2M.Text)
[Code] .....
How Would I Go About retrieving All The Times Between Say "21:20" & "22:30".
How do I tell if the current time is between two other times? ie. is it currently between 8:00 AM & 4:00 PM.
