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

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.

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.

well Thank

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 :).
Hey try this..

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

thanx .. this is helpful to me ^^

it works perfectly.
thank you so much.
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?

Thanks, It's Really Good

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!
