Casting Problem

liorlankri · November 25th, 2004, 08:07 AM

I have this code

SUB Page_Load

Dim strMyDate = Request.Form("textMyDate")
Dim DaMyd As DateTime = CDate(strMyDate )

END SUB

"textMyDate" is an <asp:Textbox> which I put in it somthing like
"14/11/2004"

But I got this Error:

Exception Details: System.InvalidCastException: Cast from string "14/11/2004" to type 'Date' is not valid.

What is the problem??

Hello,
for converting strings to DateTime you should use Parse method of DateTime,

Code:

DateTime dateObj = DateTime.Parse(stringVariable);

be carefull about IFormatProvider.

I have find another problem when date is chicking sequentially in itemdatabound event of a datagrid. code is like this..
If CDate(szStr).DayOfWeek = DayOfWeek.Friday Then
                                lbl1.Text = "<b>" + CDate(szStr).ToString("MMM dd") + "<BR>" + Mid(CDate(szStr).DayOfWeek.ToString(), 1, 2) + "<b>"
                            Else
                                lbl1.Text = CDate(szStr).ToString("MMM dd") + "<BR>" + Mid(CDate(szStr).DayOfWeek.ToString(), 1, 2) + ""
                            End If

but when date string is "29/2/2006" then its showing an error....
Run-time exception thrown : System.InvalidCastException - Cast from string "2006/2/29" to type 'Date' is not valid.
I can i chek this date...if it not valid then i should go for next loop.
