问题 I have a problem. I need write a C# program Input: Allows the user to enter multiple lines of text, press Ctrl + Enter to finish typing Output: Standardize by, rearranging lines in the right order of increasing time.

问题 Here's my problem. I am trying to get raw input from attached devices. I am using the information on MSDN to figure it out, but it's been very difficult for me to make sense of some of it. I believe I have successfully created a RAWINPUTDEVICE object and registered a device with RegisterRawInputDevices(). Now I am trying to figure out how to use the GetRawInputDeviceList() and GetRawInputDeviceInfo() functions. The big trouble is trying to understand the parameters they take, which includes a

问题 I have ConstraintLayout with ScorllView and Button below it (attached to bottom of the screen. When I am editing EditText input inside ScrollView. Then appearing keyboard is moving my ScrollView content up (desired behaviour, so I can scroll to the end of it) but it also pushing button up (undesired behaviour). I think I can change windowAdjustMode, maybe I could detect keyboard showing and then hide this button? But this two solutions aren't perfect. XML: <?xml version="1.0" encoding="utf-8"

问题 I want to use a std::string for the SendInput() function. After doing some research, I found that the VkKeyScanEx might help but the code needs additional logic for uppercase or special characters. In the latter case I realized that I can simulate a SHIFT key press, send the lowercase key input and then it would come out as uppercase. However, there are also the "special" characters like !"§$%&/()=? which need a held down SHIFT key to come out correctly. Furthermore, there are also the

问题 I've used WIN32API calls in the past to simulate keystrokes without much trouble. Even now, at a superficial level, it seems to work. I'm using the Win32 SendMessage call to send a WM_KEYDOWN, WM_CHAR, WM_KEYUP message to an instance of Notepad. And sure enough, whatever I send appears in Notepad. But while using Spy++ to inspect the messages; I noticed that my sent Keystrokes were noticeably different than the keys I had actually typed or the ones created using Windows built-in on screen

问题 I have a game in which the player can move using the arrow keys, I when I hit the up or down arrows the screen also moves. Is there a way to disable this?

问题 I'm trying to implement a keyboard with a TextView that updates with each keypress, but it won't show up on the screen. It should appear above the top row of letters. When I run the keyboard, the keys show up with an extra row on top but nothing inside <Keyboard xmlns:android="http://schemas.android.com/apk/res/android" android:keyWidth="10%p" android:id="@+id/keyboardView" android:horizontalGap="0px" android:verticalGap="0px" android:keyHeight="60dp" > <Row> <TextView xmlns:android="http:/
