Need to change datetime with time variable in this code, i tried bu it gets error

I need to obtain time values from a SQL DB. However, I was able to set the datatype for the respective column in the SQL table only to "datetime" as there is no "time" option in the dropdown list in the Visual Web Developer. Namely, I want to bind a Listbox control only to the time data (i.e. not to "dd-mm-yyyy hh:mm:ss"). I tried to convert the datetime values to string and then extract the last 9 chars that refer to time.Unfortunately, my attempts to do that with SubString have failed:
weekDays.DataTextField=Convert.ToString("Start").SubString(length("Start")-10,9)
where:
weekDays - ListBox

View 1 RepliesI try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?
View 7 RepliesI 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.

I have a datetime variable (00:00:00) and I like to increment with a timer every seconds...minutes.. hours...etc...

How can I "truncate" a DateTime variable so that only e.g. the current minute remains?
Like in:
Dim myDateTime As DateTime
myDateTime = Now
.... (what would have to come here)
If Now is e.g. 15:43:21 then leave only 15:43:00 in the variable?
I want to filter my results with respect to date and time....I have date stored in a separate field which is of datetime data type...Another field stores Time value but as it is a datetime data type so it stores current system date along with the entered time. Now when I filter results using date then it runs well and shows the results between specific period like between dates from 12/10/2011 and 12/15/2011...But when I want to show results with respect to time it doesn't show any results...
I am using dataadapter and dataset for retrieving records from the sql server database... Please tell me the solution for comparing time value taken from the textbox with the datetime value stored in the database so that i get results between specific time like between 12:00 pm and 6:00 pm.
Actually I have datetime value stored in the database. What I am taking from the textbox is a time value. I want to extract those results from the database which are between the given time value....To be more concise, my application is a booking system for a sports club and provides an option to view alreaady made bookings.. Here i offer two options either to view all bookings for a specific game or to filter bookings. In filter bookings one option is to filter through date and time...Date option is running okay but problem lies in time part...I provide two times but unable to view bookings between them...
My code is:

I get unexpected results when I use DateTime.ParseExact.
Here's my test code:

It looks like it's because the day is systematically added by ParseExact even though I only specify the time in the format. My question is: How can I read just the time with DateTime.ParseExact?

I prefer to solve this problem at application rather than db level. NOTE: DueDate in database is of type datetime. I'm coding in C# interacting with Sql-Server. I hope my question is clear enough.
So I'm kind of new to VB and am just playing around with a little project, I currently need a loop that is constantly checking the systems clock to see if it's equal to a certain time.

I am exporting data from an sql table to an excel spreadsheet in Visual Studio 2008. There is a field that is date/time that I only need the time part of (hh:mm). I am using the Convert command to do this, but I am getting the error 'Undefined function Convert in your expression'. Is there another function I should be using? Or am I missing and Import command at the top?Here is the code (field TimeofFall is the one I am having trouble with):

I've got a calendar app where we're loading up a DataTable from one method, then merging the results with another method - both methods return the same type of data and the same columns. One of the columns in the results is "start_time", which has a date and time. What I want to do is sort the entire, merged, DataTable by the time in the "start_time" column, disregarding the date completely. I've gotten this far, but can't see how to get it done:
Public Function GetDates(ByVal dStart As DateTime, ByVal dEnd As DateTime, ByVal nPageId As Integer) As DataTable
Dim dt As DataTable
[Code]....
I think I need to create a new column and grab the time from the start_time column and then re-sort the table

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

Of course I can get the offset from GMT using the "z"/"zz" formatting option, but that doesn't tell me if DST is in effect for the current timezone or if the current timezone is in standard time...or if DST/Standard time aren't even an issue in the timezone for the system.

I am doing work on a new logging database that I have decided to use UTC datetime to store all datetime values since our company spans timezones and multiple sources and timezones are logging events.However the problem that I cannot get my head around is formatting the datetimes in my datagridview for my user application.Our applications use mostly LINQ to SQL to manipulate our data from generic SQL CRUD calls, so I am hoping I can mask/format the DGV to get the conversion or some LINQ function rather than having to write special SQL stored procedures to do it every time I need to display the data.. (I have found multiple sources that explain how to do that)
View 1 RepliesI have been dabbling in VB before and i played around wiht linq to sql back then but im wondering what i should go with here.I need to have a list of people.. They should all have their own id nr.
The people in the list are supposed to keep a record of values changing over time with a datetime stamp. (In my case its numbers from a test outcome of blood)You have to be able to add people and delete people. All records will be deleted too.A Chart will read information from the records and display changes over time in chart.I was thinking of doing it with linq to sql and i was kinda aiming at Creating datatables with id names from the script
Havent found a way of creating datatables from a script though..I was hoping for a solution like that.. And i was hoping id be able to search databasetable names.
