Call my application through keyword

Question

my problem is very simple, but implementation can be hard!

I want that my application (Windows Application:: Visual C# .net) is launched whenever the user clicks some keys combinations (on his keyboard).

For example it types "Ctrl+W+W" and my application open, that's all, I want the simplest implementation, less code, memory...

Thanks :D

Answer 1

I don't think this is possible in the way that you framed this question. What is possible, however, is to have your application run automatically on startup without showing any forms, have it hook into Windows to monitor all keystrokes (I'm not sure how to do that part, exactly) and then show a form when the user presses a particular sequence of keys.

So in other words, your application would have to be running from the time Windows starts, but only show itself (make a form visible) when the user clicks a particular key sequence.

Update: here is a link to an article that discusses how to do global keystroke capture using C#: http://blogs.msdn.com/toub/archive/2006/05/03/589423.aspx.

Answer 2

You would need to write a keylogger type application in conjunction with your app which monitors for keyboard events. Once your specific shortcut is triggered you could then load your application.

See here for information on how to capture keystrokes.

Answer 3

Create a shortcut to the application, and assign a hot-key combination to the shortcut. Depending on the O/S, not every keystroke combination can be assigned to a shortcut, e.g. you may be able to assign Ctrl+Alt+W but not Ctrl+W+W.

Answer 4

On Windows, you can create a shortcut (on the desktop) to your application.

When you open the properties of the shortcut. On the second tab (labeled shortcut), you can assign a shortcut key. But you can use only CTRL-ALT-key shortcuts.
