trying to write a program to flag a Key_up or Key_down event throughout the system, but I'm having a hard time with the implementation. I've seen a few posts on here that link to outdated articles on Global Hooks, but they are usually so old I cant get source code working, or theres really no explination of how it works.
I'm looking for some sort of implementation that's relitively simple (ie a library or DLL I can use, or if it's implemented by Visual Studio 2010 somewhere) as opposed to having several classes and files devoted to making a global hook.
The use of my code: I essentially want to extend the CTRL+C function to detect if CTRL is pressed, and if C and 1 are pressed (CTRL+C+1) I copy, but also store the copied text onto a notepad document.
So with that in mind it seems really extensive to design all this code only to hook onto the KeyDown/KeyUp that will be used for only 1 key
if this question has been answered recently please link me and I can close/edit this to not be redundant
OK, so almost immediately after posting this I found the sollution by re-wording my search :/ sorry to be 'that guy' everyone. BUT in the spirite of helpfulness here is a link to a SUPER quick way to get global hotkeys in your application:

this works for both creating new hotkeys and overriding old ones

I can see a similar question that has been answered here (How would i play a specific song in iTunes through java?) but it doesn't really answer my question (I don't think, anyway).
I have a couple of buttons on a winform (play, pause, skip forward, skip back) and want to be able to connect these through iTunes, so as to create a 'mini media player'.
However, I am having issues (obviously, or I wouldn't be writing this :P) with all this 'COM' malarkey. I have tried including (nearly) all the possible references from 'Apple', 'iTunes' and still can't seem to be able to find a way of pressing the button 'play' and actually playing a song in iTunes.
I have a button on click event (i've called the button btnPlay). But does anyone know the 'correct' or 'efficient' way of connecting iTunes to winforms?
I've heard about something called sendKeys, but I'm a total noob and have really no idea of how to create this sort of thing.
PS. I've also tried to find a refence for using iTunesLib; (from http://blogs.msdn.com/b/noahc/archive/2006/07/06/automating-itunes-with-c-in-net.aspx) but this is a dated post, and i'm not certain this namespace is available anymore (well, I can't find it anywhere in the Com references anyway.
As always, any help much appreciated.
Add a reference to iTunes 1.xx Type Library (it will be in the COM list of references).
Then you can use iTunes app as so in your click event
iTunesApp app = new iTunesAppClass();
app.Play();
you will need to perform the following step to embed the the COM iTunes app.
Go to the Solution Explorer.
Right click on References –> iTunesLib and hit Properties.
Set “Embed Interop Types” to False.
I want to build a win app using C#...
I want this app to accept letter from the keyboard... and I want that to be done either the text is written via this program or another... its will be much better if I can choose programs I want to spy on...
in another words... I want my program to get every thing presses on the keyboard and everything is being written on firefox,opera,internet explorer witch are running at same time with my program...
You need a global keyboard hook, which will allow your application to listen in on keyboard input events system-wide. You implement this by P/Invoking the SetWindowsHookEx function and specifying the WH_KEYBOARD_LL flag for the idHook parameter. The entire process can get slightly complicated.
But it turns out that you're in luck. Stephen Toub has already written the code for you here on his blog: Low-Level Keyboard Hook in C#. Just drop this into your project and you're in the spy business.
I believe what you are looking for is a keylogger...
if so you can find information on:
http://www.axino.net/tutorial/2009/02/keylogger-in-c-introduction
There's a fairly comprehensive article on this over at Code Project: http://www.codeproject.com/KB/system/KeyLogger.aspx
While that article is based around C++ etc it covers a lot of the technical details you need to know.
There is an example C# project here: http://www.codeproject.com/KB/system/simple_key_log.aspx.
I'm creating a utility for my mother-in-law in order to remap CTRL-C and CTRL-V commands to one signal button on her keyboard to assist with at home work. On the first press it will commit a COPY command. Next press will be a PASTE command. Since my little application won't be in focus I'll need the use of GetAsyncKeyState. Right now I'm attempting to map this all to the tilde key. How do I kill the tilde key from actually passing to the field selected and overwriting the data or appending itself to the pasted text? Could either use C# in any .NET framework or VB6 for this little applet.
I understand the answer I'm looking for could assist in creating malicious software so if anyone should feel the need to not share or delete this question then by all means do so. I'm looking for an answer to a real issue or situation. I know I could map to a none typing key like Scroll Lock or Caps Lock like some other utilities out there but both of these keys are used at this point in time and not quite an option.
You going to have to do a global keyboard hook (see VBAccelerator for some details on global hooks in VB6), and then not pass on the message once you have received CTRL-V or CTRL-C and then act on that.
i want to do a application which works in background and read all keys pressed by user and save it in file.
i start to write it in Win forms and use keys Pressed event but it works when form is focused:/
It is another way to do it? i hear about Windows Service, but i never use it :/
You can do it with help of these:
DirectX look into MDX
KeyLogger Application for C#
Creating a simple keylogger in C#
I don't know your reasons, but I just hope they are "good".
After doing a lot of research looking for a good code to use to achieve this, I've decided to create my own C# Keylogger API. It's very simple and clean:
api.CreateKeyboardHook((character) => { Console.Write(character); });
You just need to pass a callback and the API will return the key pressed by the user, among other things like: the screen the user was in that moment. Obviously, it works in background.
More details here: https://github.com/fabriciorissetto/KeystrokeAPI
I'm assuming you want to intercept all key events to all windows:
I wouldn't recommend C# for this. You'll need to drop to the Win32/64 API, which can be done, but you'd be better off using Visual C++ / something without training wheels.
There are several ways to do this. The easiest, by far, is to register a hook for keyboard events. Implement a basic service and handle the key-press events in your main loop / event handler. You can also just brute-force the keyboard state in a tight polling loop, but this will make the CPU cry.
There's 1,000,001 ways to install your own keyboard driver without admin privileges, but you're going to need to find one yourself, assuming you go down that road.
I seriously doubt that anyone on stackoverflow will help you create a key logger. You're going to need to dive into the bowels of the Win32 API and, likely, figure it out yourself. It isn't difficult if you have a solid C background. Windows "security" is little more than smoke & mirrors.
In a C# WinForms application (on .NET 3.5, probably 4.0 soonish), how would you go about allowing the user to define their own macros? For instance, a user could want the key press CTRL+K to mean clicking a certain item in the menu, and entering some text in the dialog opened by the menu, before pressing "Ok" to close the dialog.
Ideally, our software could provide a macro-recording functionality, that would enable a user to just start recording, perform the desired tasks, and the stop recording to have a macro available. This a feature that they are used to from the old version of the software, that was written in FoxPro, a tool that has such capabilities built-in.
The best option for us would clearly be acquiring and utilizing a tried and tested third party library of some sorts, but ideas for rolling our own version are also appreciated.
If I were working on something like this, I would perhaps integrate a general purpose eventhandler to log events that you want to be recordable ( perhaps either as an individual handler added to available buttons or by creating a RecordedEventHandler class to extend EventHandler and then subclassing all your event handling from that - these are just top-of-the-head ideas so I haven't looked into which would be most viable ) and just use the "record macro" button as a switch for that. There are only likely to be a few different types of event that need to be recorded - button clicks, keyboard input on any text fields, keyboard shortcuts and mouse input on any mouse-input fields so it's not an enormously taxing task although of course working out how to store and bind macros and how to facilitate import and export if you were inclined to do so is time consuming but not technically challenging. I don't know of any libraries for this purpose ( although I expect some exist ) and thinking about it I'm not sure how easy it would be to integrate something like that because most peoples' needs in terms of macros are likely to be different.
If you needed to be able to log events around your application then you may find the ManagedWinApi to be helpful.
I have good experience with "command design pattern" for macro-recording functionaly. Every command fire some application-wide (static for example) event with informations abou parameters etc... The recorder listen to this event and persist the sequence of command calling.
