In the case of COM dlls they have to be registered. That is the difference between the exe and the dll. So what you have experienced is correct. .net is not going to auto register the dll for you and it expects it to be registered to use it.

Hello Ben,
Thanks for the reply, I think you are missing the point here.
VS2005 has a feature that automatically creates manifest
files for com dll's. This happens if you set the the isolated
property in the reference to true.
(see : http://msdn.microsoft.com/msdnmag/issues/05/04/RegFreeCOM/[^]
If you use this in a solution that generates an executable this works like a charm,
you do not need to register the dlls anymore. However if you do this in a web project
or webservice this does not work anymore. The manifest files are created correctly but
I have the feeling it does not work because a webservice generates a dotnet dll and no exe.
This however seems strange to me, either I'm overseeing something or Microsoft has
simply not foreseen this and we still remain stuck with dll-hell. Strange in a world
that gets more and more filled with web projects and webservices.
Kind regards,
Markuseon

I would guess it may have to do with the IIS process not wanting to expose itself to the risk of an un managed dll. When it is an exe, it runs in its own process, but IIS is kind of a whole different beast.

Is the framework available on operating systems other than windows, say unix or solaris?

Mono is the other version of .NET, it's for *nix.

No
But Open source developers are trying to make the Technology OS independent
The Project is going on called MONO

I believe Mono does work on Solaris and various Linux distros. Check out their supported platforms[^] page.

Yes
That answer was for the current framework not for MONO

To extend upon Sandeep's post the MONO framework fully implements .net 1.1 except for winforms which was too win32 centric. Instead they wrote .net wrappers for GTK. .net 2.0 support is partial but supposedly contains all the commonly used features while they're still working on the obscure additions.

Nice one !
But Why are they doing ? Is there any confrontation with Microsoft ?

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.
