A picture box won't do that. If you want to DISTORT the image, by changing it's aspect ratio, then just draw it into a new bitmap of the required size using one of the DrawImage overloads on the Graphics class. That's easy.

Kristian Sixhøj31-Jan-09 3:59 Kristian Sixhøj 31-Jan-09 3:59  This question has been asked *several* times, and I can't see any reason for disabling the task manager. I don't think the end-user would be too pleased if their task manager got disabled. Why would you wanna do this? Kristian Sixhoej Re: disable task manager when called....

Re: disable task manager when called.... Wendelius31-Jan-09 4:20 Wendelius 31-Jan-09 4:20  If you really need to disable Task Manager for some legitimate reason, it's usually done using group policy. And that again is defined by the administrator. The need to optimize rises from a bad design.My articles[^] Re: disable task manager when called.... Dave Kreskowiak31-Jan-09 4:32 Dave Kreskowiak 31-Jan-09 4:32  Your code won't work. And, you're only attempting to stop one method of launching TaskManager. Other methods include launching it from the Ctrl-Alt-Del screen, starting it from a CMD prompt, starting it from the Start/Run box, writing a small script to launch it, ... and so on... In short, you shouldn't even be trying to do this in a legitimate application.

Guffa31-Jan-09 5:53 Guffa 31-Jan-09 5:53  You can't capture the key combination alt+control+delete. It's handled by the system and never reaches your application. Despite everything, the person most likely to be fooling you next is yourself. Re: disable task manager when called....

Re: disable task manager when called.... Christian Graus31-Jan-09 8:53 Christian Graus 31-Jan-09 8:53  As we keep saying, disabling the task manager is done by group policy, if the lab doesn't want students to have access, they need to set this up, your code can't do it.

Guffa31-Jan-09 9:09 Guffa 31-Jan-09 9:09  I didn't say anything at all about what I think that you are or not are. I only pointed out that it's impossible to capture the alt+control+delete key combination. What ever you are or not are, doesn't change this fact.

Christian Graus31-Jan-09 10:09 Christian Graus 31-Jan-09 10:09  It seems to me that you're kind of dense. As has been said, the ONLY way to totally block access, is with group policies. I can think of lots of other things you could try, but none of them are fool proof. So long as the student is not locked down on the PC, they will find a way around what you're trying to do. Such as, writing a program that finds the process and kills it, or using the command line to kill it ( as someone else said ). If this is homework, then stop going in circles, your teacher should know that what you're trying to do won't work. If it's a paid job, then tell the people you are robbing that they are just stupid enough to deserve to be working with you. Christian Graus Driven to the arms of OSX by Vista.

If you want to do *something*, write a service that checks if the application has closed, and re-opens it. That might make your teacher happy, but if he's not a moron, he'll know that whatever you do, was a waste of time, it's not the place to try to enforce what you want. Overall, you are wasting a lot of time on something really stupid. If your teacher did not ask you to do this, then stop wasting your time, as you've been told over and over, you can't do it this way, not in a foolproof way.
