Which peripherals you choose can make a huge difference, and that’s why you should consider upgrading to an ergonomic mouse. As I say, experiment until you get something that works for you.Spending hours in front of a computer can be bad for your health and lead to conditions like repetitive strain injury or carpal tunnel syndrome. I may also have implemented some that didn't need to be handled, and I'm not sure the calls to the base methods are needed either. I only did KeyDown for example, not KeyUp as I presume the latter is irrelevant without the former. You may have to experiment with which events need to be handled like this. In a simple app test it seemed to do the trick and I assume it would still let stylus events through (I don't have a stylus I can test with). I've done the basic keyboard, mouse and touch events here. Protected override void OnPreviewTouchMove(TouchEventArgs e) Protected override void OnPreviewTouchDown(TouchEventArgs e) Protected override void OnPreviewMouseWheel(MouseWheelEventArgs e) Protected override void OnPreviewMouseMove(MouseEventArgs e) Protected override void OnPreviewMouseDown(MouseButtonEventArgs e) Protected override void OnPreviewKeyDown(KeyEventArgs e) This has the effect of stopping child controls from receiving those events. event handler methods of the Window and mark them as handled. You can override the appropriate keyboard, mouse and touch Preview. ![]() You might be able to use P/Invoke again to set the window style flags of your main window to prevent this (as per the accepted answer to this SO question). As soon as your "invisible" topmost window gets a stylus message that it responds to, I'm presuming focus will switch to your WPF application, thus "stealing" focus from whatever application was being used prior. One thing you may have trouble with even if you go down this route is focus. " but the amount of code involved is non-trivial and has been posted in numerous places both on Stack Overflow and elsewhere, so: try doing a search for low level keyboard hook c# wpf and you should find some code that might help! I don't really like posting an answer that basically says "do a search for. The advantage is that you can prevent those events from propagating and effectively "swallow" them, which sounds like what you need. These hooks allow you to register callback functions that get called when keyboard and mouse events are raised. ![]() This requires some P/Invoke but it's not too difficult. The only other way I can think of is to use a low-level keyboard or mouse hook. However from the docs this appears to be system-wide not app-specific so may not be any use to you. ![]() I found a Windows API called BlockInput that supposedly "Blocks keyboard and mouse input events from reaching applications". However, the WndProc (when used in WPF) is really just a notification mechanism and you can't block the received messages. That just leaves the mouse and keyboard.Īt first I thought you might be able to use a custom window procedure (WndProc) and filter-out the mouse and keyboard messages. As you do want to handle the stylus events this means you don't need to bother filtering the touch events. This seems to imply that, for a given window, you can receive stylus events or touch events but not both. These two APIs are mutually exclusive on the same HWND. (WPF) has built in support for processing Windows 7 touch input Windows 7 also provides multi-touch input as Win32 WM_TOUCH window messages. Disable the RealTimeStylus for WPF Applications on MSDN states: ![]()
