When you say click the print option, what application are you talking about.

So you want to interupt the call to the print dialog in any application, think about what you are asking, try and imagine how that could be achieved. Break the job down into small steps: Create an application that monitors all acitve applications on the current PC Identify every print option in every application the user may be running. Identify when a user clicks or hot keys a print option. You may now begin to get an idea that this is beyond your skills. It is certainly beyond mine. I suspect the reason you have not got any responses is that most people read you request, shake their head and mutter idiot before moving on, I should have!

All right, I tried to make it simple for you, I pointed out that I have no idea how you are going to achieve this and even called you an idiot for attempting it. And still you come back, this time with code. This proves you are not a troll, it does not change the fact that this is a stupid requirement. I won't help you as I have better things to do, theres an ant crawling up the wall, that will be more interesting than debating this idiotic subject with you. Good luck pal, you're going to need it!

You're not going to be able to do this using all-.NET code. I don't know the specifics of how to do it, but you're going to have to basically replace the system's print dialog to do what you want. This is FAR from a trivial task. You'll need very advanced knowledge of Windows internals and COM programming, along with some C++. Why? Because Windows Security does not have any facilities in it to do what you want. Assigning a seperate password to a resource is a very inefficient method of trying to protect that resource. Personally, I think you're wasting your time trying to do this. Windows Security is made in such a way that users have a single sign-on and don't have to worry about "yet another password" to remember to access any resource. The permissions to users and groups of users are assigned to the user based on their login token, this includes accessing shared devices such as printers. Your current method does not stop a print job from running. Since the job is already being spooled when your code figures out it is there, the print job has already started happening. The only thing you can do is pause the printer, which pauses ALL print jobs going to it, even the ones by other users who have supposedly put in the proper password. This is easily defeated because the user can just resume the printer to get around your password.

You don't. Services should not expose a user interface.

You can't do that. The next time anyone installs a piece of software or MS releases a patch, it'll overwrite or replace what you put in.

Again, the answer does not change. I've already given you the list of skills required to replace the dialog AND/OR alter the existing one. This is an extremely advanced topic, not for beginners.

You are entirely on your own with this one. Putting in a username and password is just making things more complicated than they need to be. There is no legit reason to do this and it's easily defeatable. You are doing things that noone does. This is what makes it entirely on your shoulders now...

Then he's going to have to prove it. Doing it in VB6 alone isn't possible. Personally, I think he's blowing smoke out his ass.
