[Code]...
Now the problem is this when i select the date from dtpicker1 it inserts the date in textbox in this format "07/12/11" but i need this format "07/12/2011"
conversion of date
if i used -- Date.parse("28/01/2011")
it gives me error as "String was not recognized as a valid DateTime."
so then i modify above code as -- CDate("28/01/2011").it gives me error as "Cast from string "28/01/2011" to type 'Date' is not valid." I used convert.todatetime also date.parseexact but nothing is working..

Now using VS 2008
Before I used VB 6, now I Upgraded to VB 2008.
VB6 Code
sdate = DateToString(dtpicker1 - 1)
edate = DateToString(dtpicker2)
Above code is working fine.
After Upgraded to VB 2008
sdate = DateToString(dtpicker1._Value)
edate = DateToString(dtpicker2._Value)
If I Put
sdate = DateToString(dtpicker1._Value - 1)
It is showing Error.
How can I write a code like dtpicker1 - 1

View 9 RepliesIn earlier vb.net 2008 I used the DateTime to read the date in dd/mm/yy format. I use to change the culture info to UK format. So that the date will be selected from SQL server as in dd/mm/yy format.
But I know it's not good to play with CultureInfo. Even though I used like the following manner.
Sub Form_Load()
Thread.CurrentThread.CurrentCulture = New CultureInfo("en-GB", False)
End Sub
class:
Public Sub insetTotalPaidAmt(ByVal dtSDate As Date)
Dim comm As OleDbCommand
Try
strQry = "INSERT INTO rpt_Paid_Amt(ST_ID,ST_PAY_AMT,ST_DIS_AMT) " & _
"SELECT S.ST_ID,SUM(P.PAY_AMOUNT),SUM(P.PAY_DIS) " & _

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
I am using ASP.NET with SQL Server 2005.
My date get saved in the database with data type = "smalldatetime".
I am displaying the date value into a text box called txtDate with a Reader......
Dim conn As Data.SqlClient.SqlConnection
Dim Comm As Data.SqlClient.SqlCommand
Dim reader As Data.SqlClient.SqlDataReader
[Code]....
But currently my date get displayed as "2008/06/30 12:00:00 AM" and i want to display it as "30 June 2008".
For example, today is 05/11/2009, I have two text box.
Actually it means that whatever what date i choose within the current month, the two textbox will display the last three months date.
For Example, Current Month is November 2009 , Textbox 1 will show 01/08/2009, Textbox 2 will show 31/10/2009.
Another example is Current Month is January 2009, Textbox 1 will show 01/10/2009, Textbox 2 will show 31/12/2008.
May I know how the vb.net code should look like?
how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.
We are running .NET 2.0 ASMX web services on Windows 2003 server on IIS 6.0. We have migrated a legacy VB 6.0 application to .NET 2.0 application using VB.NET. CDATE function is used at many places and we did not replace that with .NET equivalent date functions. After migration, code was working fine for many years.Recently, we have started encountering issues on our production servers where the below code fails:
CDATE("11 Jul 2011 21:10:27")
Error: Conversion from string "11 Jul 2011 21:10:27" to type 'Date' is not valid."If we perform an iisreset, the same code starts working fine. Could this be due to some recent patch for Windows server/ .NET patch?
I have a problem. I'm making a alarm clock and I need a way of converting a "dd/MM/yyyy HH:mm:ss" format into a date time format. This means I'll be able to compare the dates in a listbox using the for each function, to the current date and see whever it has passed and therfore the alarm should be deleted. It is currently in a string form so I can't use < and > to compare it to the current date as that is in a date form. I've tried using CDate but it doesn't work as it only will convert these formats:
"August 12, 2004", "2:07:30 PM" and "August 12, 2004 2:07:30 PM"
