Reading the newsgroup FAQ with care should help you, provided that the
version you choose is not too recent.

Since new Date() accepts both "13/11/2008" and "11/13/2008", one
cannot rely solely on new Date() . Indeed, even if you try all
browsers that you have, you still cannot rely on it, as date string
formats are not specified in ISO/IEC 16262.

You will, therefore, need to know something about the possible formats
that you may encounter - for example, will the month always be a word
rather than a number? May it be abbreviated? How much?

XP sp2 IE6 accepts new Date("Ju 30th, 2008") giving July 30th.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.

Check DateTime format

by: Dan S | last post by:

My application asks the user to enter in a date - in the mm/dd/yyyy format. Is there any quick and easy way to verify the date the user enters is formatted correctly? Right now I'm calling DateTime.Parse() and catching the FormatException but it seems this is a bit inefficient - catching the exception that is. There is some pretty obvious delay while it traces back up the call stack. Is there a better way? Something that returns a bool...

The data at the root level is invalid exception

I get the following Exception "The data at the root level is invalid. Line 1, position 642" whenever I try to deserialize an incoming SOAP message. The incoming message is formed well and its length is 642 bytes ( I have appended it to the end of this message).

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
