Thanks and Regards

No, there isn't. The .NET Framework is Microsoft's implementation of the Common Language Infrastructure specification, or CLI, that Microsoft invented. The CLI is a set of international standards ratified by ECMA and ISO. I'm sure you can find out more by looking up "Common Language Infrastructure" on Wikipedia.

Hi!
i am doing licensing of my application which is developed in C#. I generated a license key and stored it in registry at location HKEY_Local_Machine\SOFTWARE\[App_Name]...but soon after doing this i came to know that this location is accessible by any one and any one can change/retrieve license key from there.
I want to know where can i store license key so that it is secured and not accessible to anyone except my application.
Thanks in advance...

Any location is accessible to anyone, and as your app is in C#, it can be decompiled, so anyone can see where you get it from. You need to ask yourself, how likely is your app to be pirated, and how much do you stand to lose ? If it's a lot, then you need to move some core functionality into a C++ dll, which also handles your licensing. The app must not be able to work without the dll, for this to work at all.

This is also the only solution that, so far, I can imagine. But IMO it is weak, because maybe simple to hack the DLL call. Have you an other idea to improve security?

The best that you can hope to do is slow somebody down. Anybody armed with sufficient assembly knowledge and a decompiler can get past even the best licensing scheme given enough determination.

Hi, thanks for reply...
if any location is accessible to anyone then what usually people do to secure their application? putting core functionality in a separate DLL seems a very time consuming way...is'nt there any other way...?
Is there any way i can do it using code, may be by using a different encryption technique or some thing else....?

Actually it isn't: you have only to put authentication functionality there. Anyway it's a relatively weak solution.

Thanks for reply...
I got your point! i was thinking of core functionality as the major functions of application, but thats easy to put just the authentication functionality in dll.
Since this is the only available method to make application little bit secure, then i think i should go for it...
Thanks again...

You may also use a NET code obfuscator, but i don't know how secure it is.

Any technique is a realtively weak solution!
The whole idea behind copy protection looks great on paper, until you get a few bored teenagers involved.

But some are more stringer than others (but it also depends on how much is the teenage bored, of course).

Afternoon all,
I have quite a few textboxes on a form. Is it possible to pass these to a single keypress event handler and then determine therein which textbox sent the message?
Many thanks in advance

The sender argument ( the one that's an object ) is a reference to the control that generated the event. You can check if it's a particular textbox directly, or cast it and then use the tag or name properties.

Guys
One more thing just occured to me. Is it possible to get the value contained within the textbox from the object sender? I have the name of the textbox by querying the sender object, but can I also get teh value contained within that textbox by similar means. I cant see anything obvious like .value for instance
Many thanks
Colin

Oh yes. It's also very handy. Of course you have to identify the control that generated the event by inspecting the sender argument of the event handler.
