Hi,
is there possible to lock source code?
i want to poblish some control source code.
i want to lock the source code, that user can only read it cann't be change it.

I am not sure what you mean by "lock". If you compile your control down into a .dll this will prevent them from changing the code in the dll, however it wouldnt prevent them from disassembling it to get the source code.

With .Net there is no guarenteed way to completely hide your source code. There are a few things you can do to stop people changing it however.

1) Obfuscate your code. Visual Studio comes with a simple .Net Obfuscator but other commercial products are available. This makes your source code very hard or impossible to understand.
2) Add an assembly key and strong sign your DLL. This means no-one could simply rerelease you DLL as their own without the private key.
3) Add a digital signature to your DLL. This would add the benefit of identifying you as owner of the code. Again, it couldn't be changed or altered without removing this.

If you are wanting to publish the source code itself then you aren't going to be able to "lock" it. If a user could read it they could always just copy/paste or re-type it to reproduce it. About the only thing you could do is make it more difficult for them to copy it. For example you could publish it as an image instead of as text. Then they'd be forced to reproduce it visually.

thanx,
where can i find good articles about option2 and 3 ?

nice,
but when you right click of some code in dot.net,
for example, see flowing code:
int a =10;
when you right click on word "int" and select "Go to defenition" you will be forewarded to a page that show some code of Int32 structure..
when you click on that page bye mouse, you will be get a message that shows you a message like this:
"cann't currentyli modify this text on the editor, it is read only "
but you can see some code like :

public const int MaxValue = 2147483647;
public const int MinValue = -2147483648;
public int CompareTo(int value);

and so on.
i want to creat a page like this.
it's not important for me which user can copy my code.
i want, user cann't be able to modify my code

thanx
regards

That is purely a function of Visual Studio. It's showing you "code" from the assembly metadata. It is showing this to you in its own viewer.

If you distribute an assembly and protect it as suggested earlier, when someone consumes your assembly they'll likely see a similar view of metadata and it will be non-editable.

Ok,
thanx peter for your verry fast reply
can you help me about option 2 and 3 on post 3 ?
regards

Sorry, I have done neither. But you should be able to find ample examples online that describe either process.
