lock a dll to block dll calls


FireFox
 Share

Recommended Posts

if the dll can be unregistered, you could use the command regsvr32 /u thedll.dll, though if you're talking about a Windows dll, you may end up blocking more calls than you'd like to

It's maybe a solution, but I want it to be non-unlockable by another app.

@Jos

Any trick?

Can you describe why you want to block a Dll?

Plus, if you did find a way to do this, you'd be violating the rules of the forum and we wouldn't be able to help with it.

This screams malware, even if what you want to do might not be malicious, the concept would be definitely usable as malware and thus would violate the rules.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Throughout the runtime of your PC, the system will need to access it's dll files.

Even if you did find a way to block access to them, I'm 100% certain you would hard crash it.

Well, it seems the only way to do it is by drivers like the GameGuard is doing when blocking (something like this) winapi functions for some applications like Skype (e.g of errors : Could not get window handle; create device context)

I imagine they protect their own dlls, windows and processes rather than OS dlls.

I don't know much about it to be honest, beyond it would destabilise <sp> the OS.

Not that much. There is some applications that you can not run unless it craches. Meaning that it blocks something.

I'm almost sure it blocks (in a certain way) OS dlls because to get a window handle I don't see another way to do it.

I'd be willing to bet that you would have problems getting a handle to a window it is guarding

But all other windows would be fine. That is because it would be manipulating the guarded

window and its parent process.

FireFox,

I am afraid this is not something we want to discuss here, sorry. :)
