Never ever attempt to do such a monstruousity!
I would qualify your software as malware.

I deleted your answer. Don't try it again.

cheap work... nothing else

Guys, guys, he wants the solution, not advice,so Bhavna, having the solution will cost you 350 USD, having it integrated to your class/application will cost you the same but per hour, you can wire transfer the money to my account, when I get the confirmation from the bank I'll send you an email, if you send me the class/application I can give you an estimate of how long is going to take me.
I'm a professional (not like you) and I'll deliver what I promise

ofcourse you are not like me.

You must have to restart explorer.exe (or your system) to view the change

Solution 1

Don't. If you change the system date format you will:
1) Annoy the heck out of your users - if an app did that to me, I would be extrememly annoyed.
2) Probably break a lot of other apps, which rely on teh user knowing what date format to enter.

Instead, use the format strings available with the DateTime.ToString[^] and DateTime.ParseExact[^] methods.
You will find a complete list here: Formatting a DateTime for display - format string description[^]

Voted 5 and proposed as answer. It is not a good idea at all to change user settings.

Manfred Rudolf Bihy 14-Mar-11 5:39am

Very good argument! 5+

Bhavna v 14-Mar-11 5:44am

I only need solution not advice...
well Thank

Richard MacCutchan 14-Mar-11 8:29am

No, I think you need advice.

Manfred Rudolf Bihy 14-Mar-11 8:44am

You tell him!
When I saw OP's response I wanted to add a snide remark, but your comment is way better than what I had in mind :).

Richard MacCutchan 14-Mar-11 8:48am

It's interesting how many people ask for help but then reject a response because it is not the 'right' answer, in their opinion.

Sergey Alexandrovich Kryukov 14-Mar-11 13:49pm

>I only need solution not advice...
Very bad, Bhavna! Be able to listen to advice and be a bit polite to the one who is trying to help. My vote of one for this note.

Toli Cuturicu 14-Mar-11 18:32pm

Try other site then. Here, at CodeProject, things don't work that way!

Bhavna v 15-Mar-11 5:13am

Don't say this again..

Toli Cuturicu 15-Mar-11 8:19am

Oh, yes. I'll keep telling the truth.
If you don't like it, don't bother us anymore.
There are lots of people who need and accept help, so... you got it.

Dalek Dave 14-Mar-11 5:47am

Good Call.

Sergey Alexandrovich Kryukov 14-Mar-11 13:49pm

Sure, a 5.

Solution 5

Hey try this..

RegistryKey rkey = Registry.CurrentUser.OpenSubKey(@"Control Panel\International", true);
rkey.SetValue("sShortDate", "d/M/yy");
rkey.SetValue("sLongDate","dd/MM/yy");

Solution 2

A very dirty hack could be to change the registry settings.

However, as mentioned by OriginalGriff, this is not a recommended practice as your users are going to be thrown into a tizzy (unless this is their requirement).

Sorry I voted too quickly before I taking a serious look.
OP asked about changing the date format. Your link goes on about setting the local time and date or did I miss anything essential?

sandeepbongale19@gmail.com 2-Sep-13 8:33am

Thanks, It's Really Good

Abhinav S 14-Mar-11 5:43am

Thank you Manfred. :)

Manfred Rudolf Bihy 14-Mar-11 5:46am

Look again Abhinav as I changed my vote. Can you clear up my confusion?

Manfred Rudolf Bihy 14-Mar-11 8:45am

Re-re-adjusted my vote! 5+
I think the best advice for OP is not to change that setting!

Bhavna v 14-Mar-11 5:46am

I only need solution not advice...
well Thank

Toli Cuturicu 15-Mar-11 9:21am

No, you do not!

Dalek Dave 14-Mar-11 5:47am

Good Link.

Manfred Rudolf Bihy 14-Mar-11 6:13am

Can you clear my confusion then? I thought the question was about changing the format and not the date nor the time?

Abhinav S 14-Mar-11 7:58am

Looks like I missed that too.

Abhinav S 14-Mar-11 8:02am

Updated my answer with a solution that could work. However, that solution is a very very dirty one.

Manfred Rudolf Bihy 14-Mar-11 8:46am

Re-re-adjusted my vote! 5+
I think the best advice for OP is not to change that setting, for the reasons given in Griff's answer.

Abhinav S 15-Mar-11 0:12am

Thanks. Yes that is fair enough. I came across a number of other posts that suggest the same thing - do not do this. :)

Sergey Alexandrovich Kryukov 14-Mar-11 14:53pm

I edited it for grammar.
