My form has a subform with a few fields including a datetimepicker.When I select other items in the subform they save to that particular record within my DB no problem, but when I use the datetimepicker it does not seem to bind.
View 1 RepliesI 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.
From the WINDOWS Date & Time settings FORM is this accessible as an alternative

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"
DateTimePicker1.MaxDate = "07/02/2010"
Running: Win7Pro, VS2010Pro
Try this:
New project (WindowsApplication1), new form (Form1) with one DateTimePicker (DateTimePicker1), one TextBox (TextBox1) and one Button (Button1).
The DateTimePicker's properties changed are: ShowCheckBox: True, Checked: False
The code on the form is:
Public Class Form1
Public Sub New()
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Me.DateTimePicker1.Value = DateSerial(2011, 1, 31)

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 1 RepliesI support a desktop application containing datetimepicker components.A child form loads within an MDIcontainer, updating components from data retrieved from a SQL table, allowing users to make modifications. A text component hides the current form and displays another form.When the user returns from the other form, one of the datetimepicker component is unchecked and the date is set to the current date. Tracing through this application, I do not hit any code that resets this component.Other datetimepickers located in my current form are not affected.I'm providing the routine used to display another form, and the routine used to return to the current form.

Does anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem
View 4 RepliesI 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?
The application contains 14 DateTimePickers, 2 on each tabpage of the form.he user most commonly ould open the application, input values on tabpage 1 and calculate the results. Some months later input values on tabpage 2 and calculate the results and so on.
