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
Message="Index and length must refer to a location within the string. Parameter name: length"
ParamName="length"

I am located in the NorthEast US. My problem is properly storing a string in European date format (today is 23/1/2012).
For example the string '12/1/2012' is stored as as December 1, 2012 not January 12, 2012.
How can I dimension a DateTime variable to store the European date string properly?

When I looked at the database record, the datetime saves like this: 4/6/2012 04:42:28 PM
because I've save it using dbtype.string
Now, I'm getting the date only, not including time, this is my code:
Private Sub getpapererror(ByVal ddate As String)
Dim sqlstr As String = "select * from perror where date(ddate) = $xddate"
Dim sqlcmd As New SQLiteCommand(sqlstr, mycon)

I'm creating an XML file from values contained in a datatable. When I try to write an XML date value, I receive "String not recognized as a valid datetime. The dates that are stored in the datatable column is in this format "yyyymmdd". I tried to use XmlConvert.ToDateTime but I get a warning about the method being obsolete and I'm not sure what serialization mode I should use. How would I format the date from the datatable to MM/dd/yyyy and write to an XML file?
XmlWriter.WriteElementString("Add date", XmlConvert.ToDateTime(dr("Date_Added").ToString.Trim)))

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.

I'm developing a VB Web Application in .NET3.5 using Visual Studio 2008. I'm having difficulty in validating some XML as a string before I add it to a HTML form to post to a 3rd party. I have an XML schema file from the 3rd party to validate against and at this point I'd like the application to perform the validation before each post.
After searching I've found references to a XmlValidatingReader but this is obsolete and I'm having difficulty finding another way to do it. Also all the good examples are in C# - for now I'm stuck with VB. This is what I have so far which I'm looking for with! Public Function ValidateXML(ByVal strXML As String) As Boolean

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 want to insert only date into the db but in the following statement that I've wrote which inserts the date in mm-dd-yyyy hh:mm:ss format.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & TimeLabel.Text.Trim() & "')" & "Update Blotter Set Name = UPPER(Name)"
I have tried the following code, however it didn't work.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & (CDate(TimeLabel.Text.Trim().ToString("MM/dd/yyyy")))& "')" & "Update Blotter Set Name = UPPER(Name)"

I also tried format the TimeLabel as below but still didn't work. [code] TimeLabel.Text = CDate(DateTime.Now).ToString("MM/dd/yyy")
