capslock

问题 I am creating a login thing and I have this problem that every time I click on this "Show Password" Button and the Caps-Lock is activated, a Warning pops up and won't leave (at least I think it won't, which for the end-user would be even worse) I would like to get rid of this warning completely. Before redirecting my question to this question: How to disable system's caps-lock notification on Textbox I have already tried that. Private Sub ShowPassword_MouseDown(sender As Object, e As

问题 I've been searching for a way to identify the status of the CAPS LOCK in Python 3 and the only thing I've found applicable was a post here in Stack Overflow answered by Abhijit stating: You can use ctypes to load user32.dll and then call GetKeyState with nVirtKey = VK_CAPITAL (0x14) def get_capslock_state(): import ctypes hllDll = ctypes.WinDLL ("User32.dll") VK_CAPITAL = 0x14 return hllDll.GetKeyState(VK_CAPITAL) I've applied this to my script, but the value returned is not the anticipated 1

问题 I saw the vim wiki tips and it says that in order to remap Esc to CAPS LOCK you have to edit the following windows code: REGEDIT4 [HKEY_CURRENT_USER\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,01,00,3a,00,00,00,00,00 Is it possible to remap Esc to CAPS LOCK by only adding or modifying lines in the _vimrc? 回答1: I recommend that you use AutoHotkey for this. You can do a per-application hotkey change: SetTitleMatchMode,2 #IfWinActive,VIM CAPSLOCK::ESC return

问题 I would like a specific example on how to turn caps lock on if it is off. I know how to toggle the key, I have been using this: toolkit.setLockingKeyState(KeyEvent.VK_CAPS_LOCK, Boolean.TRUE); That will change the state of the key whether it is on or off. But I want to make sure it is on at the beginning of the application. (The final goal is having the keyboard LEDs flash in certain sequences, which works better if I have a certain starting state.) 回答1: You can use getLockingKeyState to

问题 Is there a simple method to turn on/off Caps Lock, Scroll Lock and Num Lock on Linux (OpenSuse) using C++, what header files need to use? I want to control some device simulates keystrokes. 回答1: Solution 1 Please go head because this solution just turn on the led of the keyboard, if you need to enable the caps lock funcion too, see solution 2. // Linux header, no portable source #include <sys/ioctl.h> #include <fcntl.h> #include <unistd.h> int main(int argc, char* argv[]) { int fd_console =

问题 localRobot.keyPress(KeyEvent.VK_F); I have no clue how to make this keypress an uppercase keypress. I attempted to press VK_SHIFT and release afterwards, however that didn't work. Would it work to press the capslock button? If so, how do I do it? Is it just VK_CAPS? 回答1: I believe this might work. It presses the shift button, presses yours then releases. localrobot.keyPress (KeyEvent.VK_SHIFT); localrobot.keyPress (keyCode); //Your keycode(your letter) localrobot.keyRelease (KeyEvent.VK_SHIFT

问题 #include <windows.h> int main() { if ( !GetKeyState(VK_CAPITAL) & 1 ) { printf("caps off"); } else printf("caps on"); return 0; } but limited to windows only how to do this in linux with gcc ? what is & 1 in GetKeyState(VK_CAPITAL) & 1 ? 回答1: For the most common case of an X11-based desktop: #include <stdio.h> #include <X11/XKBlib.h> int main() { Display * d = XOpenDisplay((char*)0); if (d) { unsigned n; XkbGetIndicatorState(d, XkbUseCoreKbd, &n); printf((n & 1)?"caps on\n":"caps off\n"); } }

问题 Is it possible to check the status of Scroll Lock, Num Lock and Caps Lock on page load of a web page? I've found ways to check after a keypress using JavaScript, but that's not what I'm asking. 回答1: No, you can't get system state from javascript. You will need them to type something and then analyze the input. Probably not what you wanted to hear =/ 回答2: IN 2019, this is now possible: var x = event.getModifierState("ScrollLock"); Source: https://www.w3schools.com/jsref/event_mouse

问题 Just as the question asks, I know this is possible on Linux, but I couldn't find anything recent for Windows. Is it even possible? 回答1: You can use ctypes to load user32.dll and then call GetKeyState with nVirtKey = VK_CAPITAL (0x14) def get_capslock_state(): import ctypes hllDll = ctypes.WinDLL ("User32.dll") VK_CAPITAL = 0x14 return hllDll.GetKeyState(VK_CAPITAL) 回答2: Install pywin32 for Python 3.x Here is the example for checking capslock state. from win32api import GetKeyState from

问题 Alright, before this gets flagged as a possible duplicate, I've already tried the following code: Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK) And it is always returning false for me [see below]. Could someone confirm if this is supposed to be working, and I'm misusing it, or if it's known to be broken? If it is in fact broken, does anyone have a better method to use? EDIT: Alright, just found out something more. It appears to just return what it was at the begining
