Hi there,

Take a look at the DateTime.Parse method: http://msdn2.microsoft.com/en-us/library//1k1skd40.aspx

If you're using .NET 2005, you can also use TryParse which doesn't raise an error with an invalid date.

You can't really check if the format is in mm/dd/yy format. What if a user enters 2/3/07. Is that 2 March or 3 February?

You could considers a Calendar, three drop-downs or a date picker instead.

Cheers,

Imar

I am using Vb.net 2003 and self taught beginner with little knowledge
I have successfully validated user input by using

Dim sdate As String

        sdate = String.Format(txtStartDate.Text)
        If sdate = "" Then
            MessageBox.Show("no date entered")
            End
        End If
but still struggling at date format ie if user entered mm/dd/yy not mm-dd-yy

if user inputs in mm-dd-yy formatcan we change it to mm/dd/yy format

I apologise for mm/dd/yy and mm-dd-yy issue because both works the same way so I need not to worry about this issue any more
