How to input arrow keys other than the numeric pad side of the keyboard?

How to input arrow keys other than the numeric pad side of the keyboard?

When Mouse Filter is set to all, The physical mouse begins acting weird. Possibly because Interceptor thread does not terminate properly.

I have a problem where, when I set the mouse filter to All, the mouse begins to act up in really weird ways.

For example, even after I closed my program. It is as though the Interceptor is still intercepting the mouse inputs. When I try to click on a button, the click is not detected by windows, or a control that would be say highlighted if the mouse came over it, would not be highlighted if the mouse came over it.

The only way to bring the mouse back to normal is to completely restart the computer.

I did a little bit of digging and I suspect that one of the reasons why this problem might occur is because the thread become hostile and cannot terminate properly.

If you look at the Unload() method, these lines

            callbackThread.Abort(); // This line is not guaranteed to safely abort the thread
            MouseFilterMode = MouseFilterMode.None;
            KeyboardFilterMode = KeyboardFilterMode.None;

            InterceptionDriver.DestroyContext(context); // I also suspect this does not work as it should
            IsLoaded = false;

If anyone knows the problem Im talking about and how to solve it, please let me know.

Thanks

Win 10 Compatability

Any chance this can get an update for win10 compatibility? The referenced library is win10 compat,

License?

I am using this wrapper and would like to credit whoever made it / include your license in my project - but I don't see what license it is. I would prefer a BSD or MIT license, which would be distributed with my binary and displayed in the about dialog.

Cheers & Thanks!

Thank you all

Does it work with x64 windows7

Does this work with 64 bit windows?
Until now I had a 32 bit windows 7, and I was using http://yorick.oblita.com/downloads to intercept keyboard inputs for a small C# app.
But after I switched to 64 bit , I am unable to install those drivers and my app does not work. Don't know why? 😓 Could you give me any insights on that?
would http://www.oblita.com/interception be a better choice or they are just the same thing?

Any help would be appreciated. 🙄

How to send a key to a background window

Is this possible?
Note that the window needs to stay in the background. I don't want to set the focus for a split second and then unfocus.

Unloading From Event Handler

If I want to listen to a key press and unload on that key press, how do I go about it?

Unload() hangs when executing within the EventHandler.

Unable to load DLL

I added the DLL like it was mentioned in the description and got the error at Line 64 in the Input.cs class: System.DllNotFoundException: 'Unable to load DLL 'interception.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)' .. Did anyone got the same issue and have a solution for me ?

How can I send arrow buttons?

I can't send any arrow buttons into somewhere? How can fix that issue?

_interceptionContext.SendKey(Keys.Down); await Task.Delay(100);

Interception CreatContext always returning 0?

I followed everything as said, but while loading I'm getting context as 0 as return value from CreateContext with interception. Please help me solve this.

Can't send mouse message

Hi, anyone knows a guide or something like that on how to send mouse clicks with interceptor?
I'm able to send keypress to games pretty well, but when I set the mouse filter on and perform a real click in order to activate the interception, it starts left-clicking continously, completely ignoring the rest of the code. I think it starts doing like that when the code hit a SendKey() statement but I can't figure out why.
Every thought will be helpful since I'm pretty new to this type of "low-level/driver" input sending methods :)

How to solve mouse freeze / windows freeze / you can not click on any after playing around with interceptor?

If you tried to use input.MouseFilterMode = MouseFilterMode.All;
And everything worked but after that you could not use your mouse to click on anything?
The problem is caused by "Thread.Sleep".
If you are the one who use "await Task.Delay" instead to make a delay and never use the "Thread.Sleep", since the Thread.Sleep(x) will freeze your GUI for x millisecond, well, this is the solution for you.
Here is the things you can try:
Solution 1: Remove the Thread.Sleep in SendLeftClick() and SendRightClick() function - for those who didn't use the Thread.Sleep:

        public void SendLeftClick()
        {
            SendMouseEvent(MouseState.LeftDown);
            //Thread.Sleep(ClickDelay);
            SendMouseEvent(MouseState.LeftUp);
        }

        public void SendRightClick()
        {
            SendMouseEvent(MouseState.RightDown);
            //Thread.Sleep(ClickDelay);
            SendMouseEvent(MouseState.RightUp);
        }

Solution 2: Add "using System.Threading;" in your main code.

About does not function reliably and often moves the mouse in unpredictable vectors.

I had a deep study on C++ sample source and found all the location(mean x,y) changed to device location such as
int x = static_cast((0xFFFF * (center.x + position.x)) / screen_width);
This means the X and y which is passed to the two function MoveMouseTo and MoveMouseBy are not correctly or unclear. So I did some change, it works perfectly.
here is my change:
Point point = ConvertDevicePoint(x, y); mouseStroke.X = point.X; mouseStroke.Y = point.Y;
The function ConvertDevicePoint code is the following:
private static Point ConvertDevicePoint(int x,int y) { int SH = Screen.PrimaryScreen.Bounds.Height; int SW = Screen.PrimaryScreen.Bounds.Width; return new Point(0xFFFF * x / SW, 0xFFFF * y / SH); }
Then it works.

Thanks a lot for your code and help me a lot.

I tried to change the MouseState enum values with no success.

By the way, thanks for great project!

How to get Hardware ID of Keyboard?

I want to get the Hardware ID of the Keyboard in the OnKeyPressed Event. In interception there's a method called interception_get_hardware_id and there's an example for it. How can I use it?

Some part in the sample code didn't work.

I copied exactly the same code from the example. but some of them didn't work and I don't know why. The following code didn't working (with error explanation)

input.KeyDelay = 1;
// 'Input' does not contain a definition for 'KeyDelay' and no accessible extension method 'KeyDelay' accepting a first argument of type 'Input' could be found (are you missing a using directive or an assembly reference?)

input.SendKeys(Keys.Enter, KeyState.Down);
//cannot convert from 'Interceptor.KeyState' to 'Interceptor.Keys'	

input.SendKeys(Keys.Enter, KeyState.Up);
// cannot convert from 'Interceptor.KeyState' to 'Interceptor.Keys'

input.Unload();
// not support on this platform

This is not work on Windows 10

I had done follow the instruction. My code can build without problems, but it has no effect. Nothing happens, keystroke or mouse click not work on any app: games, chrome or notepad...
I did active the target app using SetForegroundWindow() before sending keystroke or mouseclick.
Is there anyone could make it work on windows10? Please give me some advice!

Cant send Keys and input.SendKey does right click

Hi, this is my code. When I try SendKey it right clicks.

            Input input = new Input();
            input.KeyboardFilterMode = KeyboardFilterMode.All;
            input.MouseFilterMode = MouseFilterMode.All;
            input.Load();

            Thread.Sleep(2000);

            input.SendLeftClick();

            Thread.Sleep(2000);

            input.KeyPressDelay = 10;
            input.SendKey(Interceptor.Keys.C, KeyState.Down);
            Thread.Sleep(100);
            input.SendKey(Interceptor.Keys.C, KeyState.Up);

            input.SendKeys(Interceptor.Keys.A);

            input.Unload();
