I have following code on .NET 2.x:
Dim pDate as Date
Dim dteDay, dteMonth, dteYear As Integer
dteDay = Day(pDate)
dteMonth = Month(pDate)
dteYear = Year(pDate)
I use DatePicker to assgin date to pDate.
If I assigned vaule as 8/2/2010, with above code, dteDay = 8, dteMonth = 2
If I assigned vaule as 8/25/2010, with above code, dteDay = 25, dteMonth = 8
i have problem when display date data from database to display on DatePicker.the error is: "Conversion from string "30/08/2011" to type 'Date' is not valid."
this vb

dtPO.Value = CDate(dtt.Rows(0).Item("po_date"))
data in database is "30/08/2011", not error if data "07/04/2011"
I need to define weeks for my app. So I want to select a certain week of a month. then I want to tick the days that apply and save those dates to a table.
View 2 RepliesI am using VB.net as well as Jquery Datepicker for getting dates.
In my VB.net code
<tr><td>
DateOfReceiving:
</td><td colspan="3">
<asp:TextBox ID="DateOfReceivingTextBox" runat="server"
CssClass="pastdatepicker"
Text="DateOfReceiving" />
</td></tr>
I want to allow enter user only todays date or past date with format dd/mm/yyyy. I want vb.net custom validation for that. How to write vb.net regular expression.
I add a date picker as follows
Friend WithEvents dtpReportDate As System.Windows.Forms.DateTimePicker
The default date picker has left arrow and right arrow which allow you to browser previous month and following month. I add a handler to date picker valuechanged event:
AddHandler dtpReportDate.ValueChanged, AddressOf dtpReportDateChanged
Private Sub dtpReportDateChanged(ByVal sender As Object, ByVal e As System.EventArgs)
'do something here
End Sub
The problem is that whenever I click left arrow or right arrow to change month, the dptReportDateChanged is triggered. I do not want this happens. All I want is that after I find a month, I double click date to trigger the event.
I have noticed that hwen i set the datetime programmatically on the wpf datepicker the writing "show calendar" does not disappear but remains visible underneath the date passed?is there a way to solve this problem

From what I can tell Date and DateTime have the same functionality. Is there a reason why I would want to use one instead of the other?

I having a problem converting a string into the date format I need. An example of the string I'm trying to convert would be 215056081909. I would like to convert that string into 08/19/09 21:50:56.The code listed below is what I'm trying to use for the conversion process. When I run the code I'm getting the error below and I'm pretty sure it's because my string has the time portion in military (24 hour) time.
Error:
System.ArgumentOutOfRangeException was unhandled
