how 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?
Is it just me or is it so that a DateTimePicker can only be used for entering dates or times but not both?
View 9 RepliesI have two date time pickers , namely "Date_of_ReturnDateTimePicker" and "Date_of_IssueDateTimePicker". Now, what i want to do is, that when i press the "total" button, the value of issue date should be deducted from the return date value, and the difference in days should be put in a textbox.

View 3 RepliesHaving problems with a datatable which consists of multiple datalogger information. Within the datetime field there are as the name suggests listed date and times entry i.e. 12/01/11 22:56:56 ect ect.
Problem is i am graphing this and when ms chart reads the duplicate entries as a series. It doesnt like it and comes up with a slightly odd interpretation. I need to get the duplicate entries out to establish a single time series.
I was proposing to clone the original datatable and run a loop to remove the duplicates. I have been trying to do this for days and have played with a whole load of examples, without success. Can anyone point me in the right direction on this.
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 2 RepliesI want to calculate the difference between 2 different times. have the following code:
Code:
tNow = Now.TimeOfDay.Hours & ":" & Now.TimeOfDay.Minutes & ":" & Now.TimeOfDay.Seconds
tEnd = iNum1 & ":" & iNum2 & ":" & iNum3
tTimeRemaining = tEnd - tNow
This works all well until, the variables are the following:
Time Now: 7:36:34 PM
Time End: 12:46:00 AM
Because it passes over from PM to AM it gives me like 18 hours difference.Im lookiing for it to return me 5 hours
ok i will try to put this simple as i can. i am a doing computing coursework and as everyone can guess it is a pathetic programme i have to build. i need to work out the time difference between two times imputed by the user. i get high marks from making the programme user friendly so i want to use normal time (hh:mm). i am struggling to calculate the differences between the times.
i have tried to do it manually by working it out by sums and i have triedd to use date variables but vb 2008 just keeps saying i need to use timespan. i have never used system.timespan and have no idea how i am meant to use it.
I am trying to calculate the difference between 2 times.
So far I have 4 labels.
Label1 = Current date and time.
Label2 = Contains the exact time that the application was last closed.
Label3 = Contains the exact time that the application was opened.
Label4 = I want this label to say how much time in seconds had elapsed between the application last being closed and the application being opened again, in other words the difference in seconds between label 2 and label 3.
Below is what I have done so far, but despite repeated efforts I can't seem to find a way of getting the time difference to show in label 4?

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
I am using VB 2008 and want to record a start date and time and then the stop date and time in a rich text box, i can get the start time into the box but so far can only stop the time instead of 2 seperate times, what i have is a drop down box with a list of computers 1-10 i was trying to get it so you picked a certain computer and that went into the text box then you started the timer and that was recorded, finally you stopped the timer and that was recorded but as i am a total newbie it does not work
Here is the code i have.
Public Class Form1
Dim time2 As Date

I'm trying to write a program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date.This is what I've got so far:
Code:
Public Class Form1
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
[code]....
That's what it looks like so far. I was wondering how you can automate the top label so it automatically comes up with the date when the program is run.Plus, I need to know how to display the dates difference (how many days have elapsed between the system date and the user's chosen date) in the bottom label.
Title pretty much says it all. How do I format the date of a dateandtimepicker to insert it into the SQL date datatype?

View 2 RepliesHow to get the difference of login time and logout time.(Eg. Login Time = login1 and Logout time = logout1).
what will be the format of the value.
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?

View 6 RepliesI have a Date variable called Time1In.
I'm getting a time value as a string from Excel, so I assign the date variable a value like this:
the string value coming in from excel is this:
30/12/1899 7:40:00 AM
my code gets the time value and assigns it to the date variable:
TimeIn1 = TimeValue(strTimeIn1)
the Date variables value is then this:
#7:40:00 AM#
which inserted into my database datetime field then looks like this:
0001-01-01 7:40:00
That causes errors when loading the page. I need to set a date value on the date variable. How can I properly append a date to the variable?
