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.

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?

Very simple, I click a button and it shows the answer in the label. The answer to this is: 00:02:38 (according to excel)
But I want my Vb.net to change the decimals into the time as excel would do so. The answer vb gives me is: 0.001833786. So how can I change a decimal into a time?
display 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 want to convert e.g. 21/06/2009 15:30:00 to seconds or a decimal number. Just like PHP, which uses a reference date (01JAN1970)

View 6 RepliesI have an SQL Server database with a table in it that has a column labeled DATE (datatype =date).The table also has a column labeled TIME (datatype Integer) that contains hours and minutes.I would like to be able to display the time in a datetimepicker also.
Would it make sense (remember I�m new to VB) to have the time as part of the date column?Doesn�t the date/datetime data type include time(7/24/1996 12:00:00 AM)?If so what is the best way to add the TIME column to the DATE column.I know I can go back to our other system (IBM iSeries) and combined the columns and transfer the data over again but that is chore (the transferring) and I want to learn how to do these kind of things without falling back on my IBM skills.It seems I should be able to add time to the DATE column of the table. None of the DATE data transferred over to this table had time with it.
Debug.WriteLine(Me.ServiceRecord.Field(Of Date)("served_date"))

I have an app that I have made. The application generates 14million combinations of numbers and inserts them into an Access Database. As you can imagine, this takes AGES (whole night) to compute. Is it possible to make the same method call twice so instead of one combination being generated and inserted, two or more are?

dim pvalue as datetime pvalue = (Date.Now.AddHours(3), Date.Now.AddMinutes(2))
above code getting error of ')' expected
No Error MessageBox.show(Date.Now.AddHours(3), Date.Now.AddMinutes(2))
In Microsoft Access I use: Hours(time) minute(time) function to get current time hour and minute. I then use loop to add to the minutes until it ends in a 5 or 0 to round it up to the next 5 minutes. e.g. 13:43 rounded up to 13:45 I use IF statement to make sure the minute does not exceed 60 to start the hour. I want to use that time to add hours or minutes to easier e.g. add 15minutes, add 1 hour ect.

The time is a Date, and the minutes to add on is extracted with regex. I was able to add the items like above with hardcoding but ain't successful when i try to do it in a shorter way.

I'm trying to make a collection class for buttons to address them as a whole, only I want to design the buttons at design time, and not add/set their properties programatically at runtime. Each button has its own image, so it doesn't seem right to add a bunch of lines of code which assign the properties when they're always going to be the same thing.Is it possible to create the controls at design time and then add them to an array at runtime? I did this, iterating through the buttons on the form and adding each of them to the class below.The problem is that once they're added they seem to be a different instance because changing their positions has no effect on the design-buttons on the form. Essentially i wanted the collection to be a reference to the items belonging to the form.Is that possible or should I be doing this a different way?[code]
View 2 RepliesI have created a user control that mimics what a label does. I realize I could have inherited the label control, but I am working on understanding the process. I wish to add items to the control. normally (in the code of my project) would do:

I have a tabgroup with 2 tabs. During runtime, I wish to add new ones. Though I can get the tabs added, I cannot seem to add the ListBox that is supposed to go with it.
In the code below, I added '*' to indicate a line I added to try and fix the problem, but (obviously) don't work.

newTab.Name = "Tab" + g.userLabel.ToString

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
