I have a string that holds a value in the format of ddMMyyhhmmss.
Example 240512024707
I need to be able to convert this date to a real .NET Date object.
I am currently using CDate but it seems CDate does not recognize the format, is there any way of specifying the string format to CDate ???
row.Item("NoteDate") = CDate(n.noteText.Substring(0, 12).ToString).ToString("dd/MM/yyyy hh:mm:ss")
I need to convert item.MergedDate, which is a date, to a string.Code as follows
If item.MergeDate.ToString() = "12/31/9999 11:59:59 PM" Then
item.MergeDate = ""
End If
Obviously this is a terrible attempt, but
I have tried = Nothing and didnt work.

I have a string variable that contains "19:39:43", I would like to convert that to a date object. When I try I get a formatexception was unhandled error during debugging. I want to convert it to format of hours:minutes:seconds but cannot see how this can be done..
Code snippet:
Dim strtxt As String = "19:39:43"
Dim Datevar As Date = Date.ParseExact(strtxt, "HH:mm:ss tt", Globalization.CultureInfo.CurrentCulture)
I tried just "HH:mm:ss" but not sure if that worked...
I'm using date in the format dd-mm-yyyy and I need to convert a string inthis format to a date type.My string is "18-01-2010" but when I do the conversion using dim TargetDate as date=CDate(TgDstr).where TgDstr is "18-01-2010", the resutant TargetDate, as note in the debugger window, is #1/18/2010# rather than #18/1/2010# which I expected.What change in code should I made to get the desired result?
(P.s. I've checked the current culture with the following line of code:
Dim str As String = CultureInfo.CurrentCulture.Name and get the result 'zh-HK'... and the date-time format I find in the control panel is also in dd-mm-yy format)

View 20 Replieshow 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

View 15 RepliesI 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'm looking for a way to convert a 5 character time representation to a date object. ie. "0937a" should be "6/16/2010 9:37 AM" or "1215p" should be "6/16/2010 12:15 PM".
View 2 RepliesI am trying to convert a string into Date (to put it later into INSERT command). My problem is that the string I am reading is always different (there is no rule what format it is going to be - as this is user-dependent).I found such piece of code on the stackoverflow:
DateTime myDate =
DateTime.ParseExact("2009-05-08 14:40:52,531",
"yyyy-MM-dd HH:mm:ss,fff",
System.Globalization.CultureInfo.InvariantCulture)
but in my case it will not work as I don't know what kind of format I am going to import.Is there any universal import function which checks all known formats? If now how should I write it?
