I've been trying to figure out how to fake, not simulate, keyboard and mouse input. By this I mean the system goes through the process as if the actual event occurred, such as a mouse click, but does not actually perform the event, such as clicking the mouse.
Or if you wanted to make the system think your mouse had moved even though it did not. Sort of a "virtual" move that doesn't actually happen/effect the mouse.
Is it possible to override the simulated mouse clicks and events to make them not actually click while the system thinks they have?
Here is a nice project that wraps the keyboard and mouse. Here is the mouse input simulator file for reference. To see the lower level work, navigate to the WindowsInput.Native namespace in that project.
Thanks guys for all of your help. I was finally able to achieve what I wanted via lrb's answer.
I used that library to fake input and in the grand scheme of things I was trying to make a mouse jiggler but not actually effecting the user's mouse in case the application was running while the user was using the mouse. Which is why I wanted to "fake" the mouse rather than move the actual mouse. Thanks again for everything this was amazing.
Icemanind I'm still curious about your idea with subscribing an event rather than having an event handler. This would allow me to induce something like a mouse click without actually clicking correct?

My WPF project required touch screen. but now I haven't touch screen. So I use Mouse event (include Muse down, Mouse Move, Mouse up ..events) to all project. but I'm very worry when finish the project , and when use touch screen, the mouse event don't working. So my problem is :
1.Is touch event support mouse event? Am I need to change all Mouse event to Touch event in my project? (actually I'm very hope I can use the 2 event both in same time. I mean use mouse + use finger)
2.if don't support, Is there any way can easy handle the problem?
My project using .net4.0. thank you.
WPF MouseEvents already have an interface to handle with touch, so you dont need to make two methods.
When you touch an button it is recognized as it was a mouse click, so dont worry about this :)
You will have to implement just the "slide" touch events but not the clicked ones.
I have written an application that currently handles clicks from multiple mouse devices.
I used this project and modified to handle mouse clicks as apposed to keyboards.
This is working fine, however now I need to know if there is a way to suppress a click event if it has been handled by my app. The app is a quiz game so the idea is that the quiz master will have (and still be able to use) 1 mouse, and the other contestants will have their own mouse (as buzzers). So when they buzz in, I don't want the mouse click events to fire in the operating system (or at least this application).
The concept is the familiar override of void WndProc(ref Message message), and so I have tried not calling base.WndProc(ref Message) when I don't want the click events to fire, but this has not worked.
Can anybody point me in the right direction here?
Should I be going down the windows hook route? I have looked at this, but I can't seem to work out how I could hook to each mouse device individually.
Any help would be greatly appreciated.
Edit:
This is a Windows Form UI project, and not WPF. So the MultiPoint SDK from Microsoft won't work.
The solution to this lies within not WndProc, but PreFilterMessage(). By intercepting messages before they even reach the form, you can remove them from the message pump causing them to never reach the control that was clicked. This also works for child controls within the form.
I answered this and posted the full source in the following question:
C# Get Mouse handle (GetRawInputDeviceInfo)
I want to retrieve mouse information to my C# application, the information includes:
when Mouse position changes
When Mouse Clicks
When scroll wheel used or clicked
I have been able to find out how to get the mouse position from this question
, but for other mouse information, I don't know yet. but I do know that I must use win api for that.
UPDATE:
I need the information globally, not over my form or my controls, in fact my form is hidden , I just need to store mouse information during my application running.
Generally individual controls want to know about mouse actions as it relates to them, which is why they have events that capture this information and you should use them accordingly.
However, if you have a need to see this information outside of your Forms then you'll need a global mouse hook. There is an article about that here: http://www.codeproject.com/KB/cs/globalhook.aspx
How to track the mouse position on the screen regardless of application.i.e. Whenever the user clicks or select something with mouse in any application, i want to display my own menu at that point itself.
Is there any way to get mouse position on the screen using c#?
To do this, you'd need to P/Invoke to user32.dll and use SetWindowsHookEx().
Have a look here:
SetWindowsHookEx (user32)
How to set a Windows hook in Visual C# .NET
That sounds like a bad idea. I'm sure you could force it with a bit of effort, but what about the other applications that may want to show their own menus when the mouse is clicked?
I have solved this issue, I used Low Level Mouse hooks and Low Level Keyboard hooks to implement the solution.
I am yet to add the Menu part of it.
is there any way to take control of all the mouse events entirely using mouse hooks? I'm developing an application (VC# exe that is) and I've to fulfill the following requirement: Whenever the application is active, it has to display a virtual cursor instead of the windows cursor and when the user tries to move the mouse, the mouse events have to be transferred to this virtual cursor instead of the windows cursor. So, lets say when the user moves the mouse, the virtual cursor should move instead of the windows cursor.
I've tried to implement this by giving WH_MOUSE as the hook id in SetWindowsHookEx() call, but the problem is that along with the virtual cursor, the windows cursor is moving too.
Is there a way to fulfill my requirement? Any input will be greatly appreciated. Thanks in advance.
Have you tried using BlockInput?
P.S: use it with care :)
