i wish to concatenate date and time from 2 different datetimepicker after concatenated I want it to be save in sql database format which is yyyy-MM-dd HH:mm:ss
I'm doing half way and my query is like below.
Dim insertCmd As New SqlCommand(Sqlstr, connection)
insertCmd.Parameters.Add("@School_Subject", Data.SqlDbType.NVarChar).Value = txtSchoolSubject.Text
[Code].....
I want to save datetimepicker value of date and time in two separate text files. Currently, when I select a date from datetimepicker and save it in a text file it saves both date and time as below:
5/11/2011 8:25:06 PM What I would like to happen is as below: Datefile.txt saves 5/11/2011 Timefile.txt saves 8:25:06 PM Alternative solution that can work for me would be, if the time (only the TIME) can be modified after saving as below: saved datetime into text file is 5/11/2011 8:25:06 PM
How can I modify the time only to say 12:00:00 PM. By doing so I would like to keep time as 12:00:00 but date can be changed by the user using the datetime picker.
Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)
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

Title pretty much says it all. How do I format the date of a dateandtimepicker to insert it into the SQL date datatype?
View 20 RepliesI have a form with the DateTimePicker control on it. When I select a date it gives a value like "date time" (Eg.: 5/12/2010 12:20:35 PM). But here the time returned is current time. What I need is for the date chosen from the picker automatically set the time to 00:00:00 instead of the time when the date was picked.

View 1 RepliesI am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.
View 2 RepliesI 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?

I was wondering what was the proper way to create a If statement for if the datetimepicker date is greater than 2 weeks from the current date.
I was thinking something along the lines of
If (datetimepicker.value > DateTimeInterval.Day(14))
but I am not sure the correct way.
I want to get the date value from datetime.now till the selected value from datetimepicker. Ex.
date Today is 08/09/2011
selected date from datetimepicker is 02/08/2012
I want to show the dates between the 2 dates mentioned. For example I want to show the value of
09/09/2011-Firstmonth
10/09/2011-SecondMonth
11/09/2011-thirdMonth
12/09/2011-FourthMonth
01/09/2012-FifthMonth
Until it reached the selected value from datetimpicker.
I have a date time picker where the dates available to be selected on it is affected by the choice made in a combo box above it. If the user selects "Express Air" in the combo box for example, the minimum date in the date time picker must be either Today or Tomorrow. Nothing before, nothing after. How do I go about this? I tried:
Private Sub DateTimeExpressAir()
If cmbShipmentMethod.Text = "Express Air" Then
DateTimePicker1.MinDate = DateTime.Today
End If
End Sub
If also possible how do I set the MAX date to like, tomorrow, or 6 days after today, etc? DateTimePicker1.MaxDate = ??
But no success. I am using Visual Basic 2008.
I am trying to take a date from a DateTimePicker, add so many days to it, then display the new date.
So far i have got:
Private Sub CalculateDateDue()
Dim RaisedDate As DateTime
Dim terms As Double

But it doesn't seem to perform the .AddDays function, but passes over it without any problems.
terms does convert to the right number, so i know thats not an issue.

View 2 RepliesThe problem I'm facing now is when I set my DateTimePicker format yyyy-MM-dd, when I put a date in that column, they will auto generate the time now.For example, i entered 2011-03-30 but they will save in database 2011-03-30 10:56:54 AM.Question here is:How can I do where i want it to be "2011-03-30 00:00:00" ?

View 3 RepliesI'm having a little problem trying to figure out how to get only the time from a datetimepicker.I've set up a datetimepicker to only allow user selection of time by setting Format to Time and ShowUpDown to True.However, when I store the value of the datetimepicker to a variable, it returns a date as well.[code]However, this seems like a really inelegant solution and I can't figure out how to get an AM/PM behind that.I feel like I'm missing some really simple solution that I'm just not seeing! There HAS to be a way to get just the time!

View 12 RepliesWhen a user selects the datetimepicker, or types in the date in the text box, the calendar then highlights that date (for instance 02/02/2009) and puts the date in the text box.
If the user deletes the date from the textbox and then selects the drop down arrow again to show the calendar, the 02/02/2009 date is still highlighted. The user can select a different date or type in a date (including the highlighted one) - no problem. But if they wanted to select the same date they deleted, they cannot. No error message, it just leaves the text box blank.
Yes, it's very rare that that happens and they can highlight a different date, then go back in and highlight the 02/02/2009 date in a matter of two clicks but they want it fixed .
Not sure how I go about getting the calendar to clear the highlighted date once it has been deleted from the textbox?
My datetimepicker hangs up at midnight and does not roll over to a new date.
