VS 2010 DateTimePicker Value?
May 19, 2012
I have a date field in my dataset, my datetimepicker is bound to it. When the form loads, the datetimepicker is default to todays date if there is no value stored in the database. Right now I'm saving by the tableadapter.update(dataset) method. Is there a way to make it write the default value (today) of the datetimepicker even if the user doesn't select a value because if you make no selection it saves nothing in the database and the user may think it's ok because there is a value (today) shown by default.
If not, what is a good way to display the datetimepicker as empty so the user will have to choose a value, or how do you communicate with the user that the date shown is not going to save?

I'm using the following code to fill a DataGridView:
Dim conz As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:BdadosCV_PARTS.accdb;Persist Security Info=False")
Dim cmd As New OleDbCommand("SELECT * FROM PECAS_IN WHERE Data >= ?", conz)
Dim da As New OleDb.OleDbDataAdapter(cmd)
[code]....
The field 'Data' has the format "dd-Mmm-yy" on the Access database. The code allways fails with a type mismatch in the criteria expression.I already tried
cmd.Parameters.AddWithValue("P2", Me.DateTimePicker1.Text)
but the problem is the same.

Basically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.

I have a contextmenustrip containing a datetimepicker. Now the problem is that when I choose another date in the datetimepicker the event for that goes through without a problem BUT the event causes the contextmenustrip to go away. The problem is the contextmenustrip must stay shown. I solved the issue with contextmenustrip.show on the end of the event, this works but this has one big disadvantage. I loose all information about the sourcecontrol of the contextmenustrip, and this can't happen.A monthcalendar lets the contextmenustrip stay after his event, but a monthcalendar is too big what cause my menu to be clumsy.

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.

How can I get the value of the year, month and/or day from the DateTimePicker if I'm trying to compute for the age? I've tried
Dim x As String = ""
x = Date.FromOADate(Val(DateTimePicker1.ToString))
MsgBox(x)
But it only gave me 12:00 AM.
and
DateDiff(DateInterval.Year, DateTimePicker1, Now.Date)
This time it said datetimepicker1 cannot be converted to date.

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.

having a bit of bother with the DateTimePicker control in .NET 3.5. I created a very simple form. It consists of just one DateTimePicker control called "DateTimePicker1". In the Load event of the form, I placed the following
DateTimePicker1.MinDate = "01/02/2010"
