QUESTION
So am trying to capture the character entered after keypressed or after the user pressed enter key.
I used this package: npm i vue-keypress, but i could not figure it out how to capture the characters. you can suggest any method other that this package.
ANSWER
Answered 2022-Jan-18 at 14:21Maybe something like this could be used?
This listens for key events without using an input field and stores it into text data when enter has been pressed.
QUESTION
I am trying to make an applescript to be able to cmd+L to get ctrl+L to clear lines in iTerm as suggested by this answer.
After copying a working, example applescript from here shown below,
tell application "System Events" to keystroke "l" using control down
I am trying to change the application to "iTerm2" as shown below,
tell application "iTerm2" to keystroke "l" using control down
so the shortcut in not global, but I get a Syntax error:
A identifier can’t go after this “"”.
Removing the quotes (this also works in the working example) brings up a different Syntax error:
"A identifier can’t go after this identifier."
What am I doing wrong?

QUESTION
I'm new to rust and the windows API and I'm trying to use the PostMessage function using the windows-rs crate. However, I'm not sure what data type WPARAM expects. I've tried guessing since the windows-rs documentation doesn't seem to say. The official microsoft docs for C++ seem to expect the constants found below.. but I get an error when I try using them with the rust crate.

...ANSWER
Answered 2021-Dec-14 at 16:48As @Jmb said in his comment, using WPARAM(VK_ADD.0 as _) should work, but you would also need to pass the LPARAM argument as required by the WM_KEYDOWN message, but if you simply want to send keyboard input then its better and easier to use SendInput
QUESTION
I made a Timer script for Minecraft that should display the time spent in the game. You can pause resume and reset the time. My next step was to make it able to save the time in a file called timesave.txt but sometimes it isn't saving the time and its just empty... If it saves the time it reads and uses it to restore the old time. This is the code:
...ANSWER
Answered 2021-Dec-03 at 09:40Add io.flush() or timesave:flush() after your write operation to save the written data to the file.
See https://www.lua.org/manual/5.3/manual.html#pdf-file:flush

idk what is wrong but it writes this into the file when it saves the value. If u need more information or have a question please ask me! Thanks for your time and hopefully u your solution!

...ANSWER
Answered 2021-Dec-01 at 14:11It looks like you are saving the Unix Timestamp to your file, you can try and make it human readable using an online time converter (https://time.is/Unix_time_converter)
Besides this, take some time to read the os.time() implementation details on this lua page: https://www.lua.org/pil/22.1.html
The time function, when called without arguments, returns the current date and time, coded as a number. (In most systems, that number is the number of seconds since some epoch.)
If you want the time in between certain action, save the initial timestamp and diff it at the end of the action. This is natively supported in lua using os.difftime(). (http://www.lua.org/manual/5.3/manual.html#pdf-os.difftime)
QUESTION
I need to make a dll which will simulate a key press. For this I found out you can use an INPUT in combination with SendInput. If you know from the start which key to simulate it is easy because you can look in the list of Virtual-Key Codes and code it from the start with those keys, but I actually need to be able to change them, so I need it to be dynamically selected. In my research I found VkKeyScanExA which is quite nice, because this dll will be used in a native function and from Java I can send a String as the requested key to be pressed, but I ran into a problem, I could not find a complete list of key Strings to give it like i found with
Virtual-Key Codes. Can anyone help me with a source that contains a list like the one here Virtual-Key Codes but for VkKeyScanExA? The problem is that if I use "4", it will use the digit 4, but what if the users whats to use num 4?! That is why a complete list would be really helpful.
ANSWER
Answered 2021-Oct-04 at 15:53After a lot of trial and error, and reading the source code from JavaFX, I found a better way to do it. I can simply get the int value of KeyCode from JavaFX and send that in a native function to C++ and not needing to send a String value I also don't need VkKeyScanExA at all. I'm not used to see an int value in this form 0x03, I though wVk can only get a String or an enum value, but for example 0x03 can be used as an int as well.
Here is a simple example in case someone is having the same use case as me:
a) In java

Answered 2021-Aug-29 at 22:30I think that a stacked bar chart for expenses and revenues over the months should work - a histogram shouldn't be needed unless you are summing expenses and revenues up over a period of time longer than a month. You can have two subplots of stacked bar charts for the different building types, with a shared y-axis between the subplots.

Trying to finish up an implementation of Conway's Game of Life in Racket and I'm adding types to everything. I'm having trouble figuring out what exactly I need to do to get the classes from the gui lib typed correctly.
...ANSWER
Answered 2021-Jan-22 at 21:12In the definition of new-timer, you're trying to get the grd field of cv.
And although cv is an instance of the class new-canvas%, its type does not include that field. You need to create a new Class type for new-canvas%. By convention, it should be a capitalized version like New-Canvas%.
QUESTION
First, here's the live application I'm working on as a study: turbo_synth
I'm making it using VueJS, however, I believe the issue is unrelated to Vue.
The issue: It all works fine and dandy, except when trying to play certain combinations of notes, for example, try playing the keys Q, W, and then 2. You'll notice the last note isn't being played and not even shown as pressed, while you could play Q, W, E, R and Y at the same time. So it doesn't seem like there is a limit, as I thought previously?
The code: I'm using vue-keypress to easily handle the key events globally.
Template part
...ANSWER
Answered 2020-Jun-23 at 01:43There's nothing wrong with your code, and there's nothing you can do to fix it — this is a hardware limitation on many keyboards.
First, imagine the keyboard laid out as a rectangular grid (in other words, 1, Q, A, and Z are in the same column, even though they're usually not directly above one another).
The limitation is that no three keys that form three corners of a rectangle can be recognized at the same time. If you hold down two keys in a row, then a third key can't be in the same column as either of the first two. If you hold down two keys in a column, then a third key can't be in the same row as either of the first two. If you hold down Q and Z, then any key on the row starting with A will work fine, but W, E, X, C, etc. will all be locked out.
Alternatively, some machines might give you "ghost" keypresses at the fourth corner of the rectangle — holding down Q and Z and pressing E will register a keypress for E, but also one for C at the same time, even though nobody pressed C.
All of this has to do with the way keyboards are built electronically, and there's nothing you can do about it in software. There are some keyboards that don't have this limitation, but you can't count on your users to have them.
