1) DateTimePicker desplays date and time in the Textbox, I want that only Date is displayed in the Textbox.
2) How i can attach DateTimePicker directly to Texbox so that on runtime when i select a date from DateTimePicker it should immediately display in Textbox.

View 2 RepliesI have a datetimepicker on my form. When I click the down arrow, it goes down correctly. When I select a date, it stays down. In order for it to roll up, I have to change my focus to a different area.Is there anyway to make it rollup when a day is clicked? It feels awkward the way it is now.
View 5 RepliesWhy this line doesn't change the value of my datetimepicker using me.gatepassbindingsource.addnew():
Me.GatepassDataSet.gpheader.gpdateColumn.DefaultValue = Now()
Implementing BindingNavigatorAddNewItem executes above line correctly. I don't want this because the bindingnavigator items are active. Coding me.gatepassbindingsource.addnew(), I can make my bindingnavigator items inactive/disabled while adding record.
I have a Datetime Picker on a form.
When I use dtArrival.value for instance, it gives me the date in the format "24/04/2010 10:54 PM"
Is there a way that I can grab the value in the format "YY/MM/DD" e.g the value would return "10/04/24"?
Also whats the easiest way to calculate the number of days between two datetime pickers on the same form? I've tried to do it and it's just a mess.
i've come across many methods online to create a datetime picker within a datagrid view, but i haven't got a proper solution. i have a DGV which takes in truck no and date of arrival. i want the second column to appear as a datetime picker so the users can be restricted from entering anything else.

View 3 RepliesI would like to capture a start and end time in format hh:mm.Instantly I thought a datetimepicker would be the most suitable component (see code below)[code]Now I'm unable to find a datetimepicker solution to allow settings of intervals like in the numericupdown control and unable to even set a mindate/maxdate in time format. Does anyone have a solution for these requests? I then thought about using a numericupdown control to capture hh:mm time but I could not find a way of doing this in ONE control rather than two whichwould involve code to ensure only valid hours/min values could be selected i.e. 0 - 23 and 00-59 and other date to string conversion/validation.For such a commonly recorded element I'm surprised to find little in the way of solutions other than third party controls.Does anyone have ideas for a way forward for a control to capture time as hh:mm with interval controls for hours and minutes?

View 1 RepliesI'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?

I dont get following desired output from a DateTime-Object: 2010-03-29 13:15:00

What I've tried is to create a DateTimeFormatInfo Object from US-Culture and use its DateTimePatterns but without success:
Dim usDateFormat As Globalization.DateTimeFormatInfo = New Globalization.CultureInfo("en-US", False).DateTimeFormat
usDateFormat.DateSeparator = "-"
ruleResult.Claim.Last_Updated_Date.ToString(usDateFormat.ShortDatePattern)
Output: 3.29.2010
What is the best way (readable,fastest) to get my desired DateTimeFormat(i need sometimes the short Date and sometimes the Date and Time like in my example above)?
Why does my DateTimeFormatInfo approach not work and makes it a performance difference when using the String.Format or ToString("yyyy-MM-dd HH:mm:ss") solutions instead of a private shared(static) DateTimeFormatInfo-Object? I'm calling this function at least 30k times and there are many Dates to format inside.
I have a problem in retrieving dateTime object from the database. I have this :
Return CBO.FillCollection(Of ObjectInfo)(CType(DataProvider.Instance().ExecuteReader("sp_SelectAll"), IDataReader))
Then When I want to display the date from the collection I get from the stored procedure. the date was truncated. It shows only the timein the ObjectInfo..there is a field call _mydate as DateTime.
I have some some dates as strings in the format dd/mm/yyyy which I need to convert to DateTime object.uggest a simple routine which I can use inside a Loop which produce these Strings.
View 2 RepliesI am having trouble with a mySQL query with the .NET connector. When I create the query, it automatically creates my parameters as objects. I usually change the type to the correct type, which in this case is Date, but I get different results passing in the parameter as a date.When I do "Preview Query" as an object, I get the correct results, but bad results as a Date. I would just leave them as objects, but it errors out when I try to pass a date in.Here's the part of my query that I'm having trouble with:
(Tickets.Resolved >= str_to_date(@startDate, '%m/%d/%Y')) AND (Tickets.Resolved <= str_to_date(@endDate, '%m/%d/%Y')) AND
(Tickets.Status = 'resolved' OR
Tickets.Status = 'rejected')

View 3 RepliesI'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.
