Look in the System.Security.Cryptography namespace for encryption classes. --- single minded; short sighted; long gone; events and delegates in vb.net Pankaj Garg24-Feb-07 19:31 Pankaj Garg 24-Feb-07 19:31  Sir/Madam, I wanted to implement the events and delegates in my program.Can somebody please provide a code link Thanks and regards Pankaj Re: events and delegates in vb.net JUNEYT25-Feb-07 0:50 JUNEYT 25-Feb-07 0:50  In some cases you may want to declare an event to use an existing delegate type as its underlying delegate.

Thanks and regards Pankaj Re: Referential classes in vb.net JUNEYT25-Feb-07 0:59 JUNEYT 25-Feb-07 0:59  An application has more than one evets such as StartupNextInstance, ThreadException,ApplicationExit and etc... Try to be specific which application event you want to use. I strongly suggest you to examine MSDN about Application events.

That is why you should browser application events under MSDN to examine each of them. Application.Exit () Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. Application.ThreadException Occurs when an untrapped thread exception is thrown. please apply to MSDN for others What a curious mind needs to discover knowledge is noting else than a pin-hole.

It's doubtful that you can add it to your app as an afterthought. To compete, you need to dedicate many man years of development.

I think, this should be easily possible. But even i dont know how to do it ? Can you please guide in this respect, if you have some knowledge about it ?

Graus, But I have heard that products like Symantec Nortan and Macfee provide interfacs for checking files for virus. Any update in this please let me know Thank you! M.

In that case, I guess your best bet is to check their sites to see which ones offer such an interface, and then buy the one you decide to work with. I have no idea, I've never done that.

This is a major task, especially if expect to support CSS and Javascript. Good luck.

You've written a couple of shells around the existing IE web control. Crash_beta wrote: i wanna create my own web browser control You'll have a TON of work to do. You'll need the Http classes in the System.Web class to request pages and build a custom request header so the server can ID your browser. Unless you want to write your own HTML parser and rendering engine, you have to find a parser and rendering library to do it for you. There isn't one in the .NET Framework. You'll also have to figure out what you want your browser to support, like JavaScript and CSS. Have fun incorporating that stuff... Basically, every newbie who comes up with this idea never has a good reason to do it. They only THINK they do. There's always a better way to do what they want.
