Time Formating And Calculation - Time Value In My Program ?
Feb 23, 2010
With a Time value in my program. Basically, I am importing a travel Time from a database e.g. 3:45 so it takes 3 hrs and 45 minutes to get from a to b. I then want to double this - 3:45 * 2 = 7:30, and then want to multiply it by a cost e.g. travel is charged at 25 per hour. so it would be total travel time = 7:30. Travel cost = 25. Total Travel Cost = 7:30 * 25. In the access db, it is stored as a text field, and then imported in vb as a string.
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
I wud like to calculate the time difference between two values.I have two values which is the in time and out time of each employee.Subtracting in time from out time should yield the time the employee has stayed at the office If the in time is 09:00:00 and the out time is 18:00:00.The difference between the two would be 9 hours.
I'm making a simple program. It is almost finish in a manner of simple function. But I have problems related to time, clock and calculating codes. I admit that this software based on cyber cafe management software. I try to make a new one and less complicated and easier to use for my shop.
I tried to googling and find some coding then try to apply it in but it won't working.
In this simple program:- 1. User click the checkbox. (time start) 2. User click the STOP button. (time stop) 3. Total RM textbox will show the total currency.
I have the following macro that does a calculation. Im trying to set it up for time. So an example of what I come up with for my Text18 bookmark is 12.45 and I want it to say 12 min 45sec. Is there a way to due this?
I need to get the sytem idle time.It must be developed in vc++ and the code should not use hooks is there any possible way of getting SystemIdleTime from taskmanager
I am using a from where i am adding the time of the employee....what i am doing is that if the total hrs worked on monday = 20 hrs and on tuesday = 20 hrs then i want to add the 20 + 20 = 40 . all of my variables are time span and that is y it resets after 24.
if the current hour is less than 21:00 (today) then show the remaining time in label3 as hh:mm:ss remaining. However, if the current hour is greater than 21:0
I have a program that I wrote in vb 2010 that keeps track of employee times in a database. It figures hours worked based on a range of dates selected using two DateTimePickers.I have it successfully working at this point to figure hours worked per day in the range for it's current practical use. But I was wanting to extend it so that it would handle over night shifts properly in case they did ever occur.Right now my code looks like this and it works for my current application:
vb Public Sub ConvertTimesTableToHoursTable(ByVal timesTable As DataTable, ByVal hoursTable As DataTable)
I need to be able to display 60 * x. X is going to be the time between hitting a Stat button and a Stop button in seconds. I need this to be shown until it is stopped. So i was thinking something like txtBox1.text = 60*time, but I do not know if that is correct and I do not know how to get that time. Also I am not sure how to continuously update the text box.
how to display the calculation of time span in text box? i have this coding and dont know how to get the value between two time.. what type of format of time span that i can use.
Dim date1 As New System.DateTime(1996, 6, 3, 22, 15, 0) Dim date2 As New System.DateTime(1996, 12, 6, 13, 2, 0) Dim date3 As New System.DateTime(1996, 10, 12, 8, 42, 0)
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?
[code] Everytime i press the Calculate Button, it crashes on my first calculation part. What im trying to do is to not crash the program eventhough i have no input in it.
I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.
Basically i'm trying making a task manager program for myself. I want to know how I can display a message box and or play a sound when system time = time displayed in listview. I have used a dropdown box for the user to select which option they would like to select - sound or message box to popup. The data for the task will be stored in a listview box. I want it so that when the date and the time is = to the date and time set for the reminder the action will follow.Here is my code so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim notext As String = "" If TextBox1.Text = notext Then[code]....
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?
I need a start date, a Total time passed until now, an average time per step, and a estimated time to finished. How can I do that? Also, I can close the application and when start up again I want to get the time counters as the last time, so How can I store that data is normal txt file (I say txt to take advantage of the ini app file which is a txt).
I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.
There is a varchar column in the database table in this format of military time 1230 or 1750 or 1320 and that field get populated into a gridview in asp. I need to convert that string to standard time. I have tried the DateFormatString and nothing seems to work.
using VS2008, targetting framework 3.5I have a rather complex UserConrol which does some of its own rendering.I display this UserControl on a form.Opening that form in the Designer creates an instance of the UserControl in the Designer, which tells me a NullReferenceException is occurring in one of my rendering methods.I have attempted to correct this by making alterations to the UserControl's default constructor, but have not found success.
Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.
When I run my app at first its keeps time accurately for the first minute or so there after it starts loosing seconds, and by the end of the day its minutes behind.I've created a class called ServerTimeTimer that has a timers.timer object that elapses every second and adds a second to a dateTime variable, and a property to retrieve the date time.[code]
