View 1 RepliesI'm using this to set the default values of the DTP controls on Form_Load:
Dim dtNow As Date = Now()
dtpStart.Value = dtNow.AddDays(-7)
dtpEnd.Value = dtNow
The problem is, when those values are grabbed from the DTP controls, Access is treating them as wrong datatypes.However, if I manually rechoose the same dates, the SQL statement will work.So, what seems is happening is that it isn't recognizing the initialized values as valid date/time values until I physically choose them.Anyone know a workaround for this or what is really going on and how to resolve this?

I have a database that has null date values in it. When I call the columns from the database with the null datetime values and display it in the datetimepicker text box using a dataset, theres always values in the datetimepicker text box. It sets everything that was in the database with null values to the current date. This is what i have..
DateOPStartedRevisionDateTimePicker.Text = ds.Tables(0).Rows(0).Item(13).ToString
I just cant figure out a way to get the datetimepicker text box to display nothing if the values are null in the database.
I have two datetimepicker controls on my form:
dtpPickup and dtpReturn
I need a way to ensure that the dtpReturn date selected is after the dtpPickup, and not before. How do I do that? And also, how do I get the values of the datetimepicker selected controls? Also, how can I set the values of the datetimepickers to these two private variables?

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)
