Is it possible to set the virtual key state / mouse button state for all programs on a computer without triggering the associated events at the same time (like setting the left mouse button to be currently pressed without sending a mouse down event). Could this be achieved by setting up a fake keyboard or mouse driver for a fake keyboard or mouse that when queried as to the current state of a key would reply giving an answer of your choice or by any other means?
Edit:
This has to affect programs that I do not have the code for running in other threads ect...
Well, I don't have a complete answer for you but...
The Win32 function SetKeyboard State() changes the state of the keyboard for the thread that called it.
I know this does not affect the entire system, but if you only need the keyboard state changed for applications you are developing, then this could be called by each program, reading in the array passed to it from a temporary file on the harddrive.
Otherwise... don't know of anything else offhand...

First of all hi guys!
I was trying to write a mouse controller app for mac os x which is reading inputs from keyboard and moves the mouse accordingly. By garbage input i will describe the input was intented for a mouse event but it creates text on screen.
Before anyone points to the fact that there is a built in one, It was laggy even in shortest lag setting and cannot registers more than two buttons at the same time (you have to press diagonals to go to the diagonal.) If you accidentally press another button when release of the accident button your motion stops. My first and last reaction was "rubbish!". Adding customization and extra features is my goal.
I want to create a key combination that will block the garbage input to be passed to other programs while it was held. But global monitoring and seems like it always passes the event. And unfortunately I see qqqqqqqwwwwwww like text in unwanted places.
I want to see that when i press q w and up, it will make the mouse go up. But i create qqqqqqqwwwwww mess on the way. My first idea was creating a view on popover and handle events there, but whenever I want to use my mouse from keyboard seeing a popover is anoying and I couldn't find a way to show the popover without leaving any garbage keyboard input.
What should i do in this situation?
You will want to use Quartz Event Taps. Note that for an application to tap keyboard events, it has to be trusted for accessibility (as in System Preferences > Security & Privacy > Privacy > Accessibility). Your app can ask to be made trusted using AXIsProcessTrustedWithOptions().
Basically, I want to bind a certain letter to scroll up the mouse reel, and do so continuously if I hold the key continuously. I need it to work even if other keys are being pressed at the same time, and only work on a certain window title/tab title in the browser.
I basically want to emulate the function of the autohotkey program for the "Attack On Titan Tribute Game"'s reeling function.
An AutoHotKey equivalent is available at:
http://fenglee.com/forum/viewtopic.php?f=2&t=7548
(Which may be offline due to unknown reasons, might have to wait)
Basically, if you download the application, set Reel In to the "x" or "e" key, it works regardless if other keys are being held. Just make sure you uncheck the checkbox so it can work in any window. It basically scrolls down for you. It also includes the source.
Or.. if I can use any other free application to do the same thing, that'd be nice.
All I want is the scrolling function and it has to be specific to a window/plugin/etc. and be able to be triggered while holding down other keys.
We're making a user-space device driver for OS X that moves the cursor using Quartz Events, and we ran into a problem when games — especially ones that run in a windowed mode — can't properly capture the mouse pointer (= contain/keep it within the boundaries of their windows). For example, it would go outside the game window and click on the desktop or nearby inactive applications.
We could fix this if only we could detect when an active application calls CGAssociateMouseAndMouseCursorPosition.
How would you do this? Any ideas are appreciated.
I dont know if this can help you
There is an option called Focus Follows Mouse
Focus Follows Mouse - The Mouse pointer will grab automatically change focus to a new window inisde this one app if you mouse over it, instead of having to click a window to get focus, then clicking to do something.

I have written a few different mouse logical layers (for bridging different input devices, etc.). I have found that hooking into the OS level WM_INPUT event is a sure way of getting very real-time mouse position information. There is also a less rigorous solution of just polling the mouse data you need from one of Windows' very primitive DLLs. They are lightning fast. You could poll on a 10ms timer and never see performance loss on a modern machine.
A program has called XGrabKey() to make a hotkey.
The user presses that key combination (while another window is focused).
The program receives control to do something in response to the key combination. Meanwhile, the program has been temporarily focused (because of the effects of XGrabKey (see man XGrabKey, man XGrabKeyboard)).
I want the program to create a synthetic X event (a keypress or mouse click) to the originally focused window. In some cases this means I need to focus that window before sending it the event (Firefox ignores synthetic events when it is not focused), which means I need to know which window it is. How can I find out which window it is?
Wait for the next FocusOut event, verify that the mode is set to NotifyUngrab, get the focus with XGetInputFocus(), and send away your synthetic events.
Did anyone notice that in Windows applications the mouse pointer doesn't change from Hourglass back to normal until you move the mouse?
So even if your application has finished a task and the mouse pointer has been set to go back to default, it will stay as an hourglass until you move the mouse. What is the reason for this, and can be it resolved?
I'm not sure if other people have noticed this but it is quite strange and it might be some kind of event-driven way to conserve OS resources.
The dialog box should maintain the logic of the hourglass. The worker thread should send a message to the dialog itself, telling it to start maintaining an hourglass thread. (You could test this by adding a temporary button to the dialog which starts and stops the hourglass.)
Another thing to be aware of is that having a second process set the hourglass of the first is an odd thing to do. An hourglass should only happen due to user action. While an hourglass is up, typically the only action that should be available to the user is "Cancel [whatever operation is keeping the hourglass up]."
Can it be resolved? Call ShowCursor(FALSE) before you call SetCursor(), and ShowCursor(TRUE) afterwards. Should do the job.
