keypress - How can I get rid of character repeat delay in C#? -

-

- There is an option in Windows to install repeat delay. This means that the delay between the first keystroke and others keeps one key pressed and I'm making a type of game and I need to get rid of this "feature".

So far I have The method has been able to find: 

  [DllImport ("user32.dll")] Use stable extern GetAsyncKeyState (int vKey); Public static bool IsKeyPushedDown (key data) {return 0! = (GetAsyncKeyState (int) key data) and 0x8000); }

But the method IsKeyPushedDown finds that the key is pressed at the speed of calling the function - so I need a loop to check if the key is down The problem is that it is now Also does not catch all keystrokes - I have a very slow loop.

The second option is overriding the ProcessMDK: 

  Protected Override Bull ProcessCMK (Ref Message Message, Keyage Data) {// Processing Keys (If Key Data == Key.lift || keydata == key.wright || key data == key.upa || key data == key.down) {return true; } Else {return base.ProcessCmdKey (riff message, keydata); }}

This really works well, but it is affected with repeating and so the speed of my monster in my game is the same:

Is the solution to the problem? Thanks

Edit: I have solved the problem with the combination of both processes but this is a very ugly solution. I still hope that there is a better solution

You should deal with keydown and key up instead of ProcessCmdKey Want more control over what happens during pressing and releasing the key.

The simplest thing to do in your scenario is that the timer that moves the monster on your form when KeyDown is removed, enable the timer (and variable Or set DeltaX and Delta which indicates how to move the monster), then stop the timer when KeyUp is removed.

edit

as an example (very barebones) 

  public class MyForm: form {Private Int DeltaX; Private Int Delta; Private contact with ArtaultAmount = 10; Private Timer Movement Timer = New Timer (); Public MyForm () {movementTimer.Interval = 100; // Let's go between the movements in whatever interval you want. Timer Tick ​​+ = new event heredollar (movement timercut); } Zero movement timer (object sender, event ergges e) {myMonster.Location = new point (myMonster.X + Deltax, MyMostar.Y + Delta); } Safe Override Zero OnKeyDown (KeyEventArgs e) {base.OnKeyDown (E); Switch (E. cacode) {Case keys. Lift: {deltaX - = movement standard; } break; Of the case. Correct: {deltaX + = movement amount; } break; Case key Up: {deltaY - = movement amount; } break; Case key.Down: {delta + = movement amount; } break; } Update timer (); } Secure Override Zero OnKeyUp (KeyEventArgs e) {base.OnKeyUp (E); Switch (E. cacode) {Case Keys. Lift: {deltaX + = movement; } break; Of the case. Correct: {deltaX - = movement amount; } break; Case key Up: {Deltae = = Amount of movement; } break; Case key Download: {delta - = movement amount; } break; } Update timer (); } Private Zero UpdateTimer () {movementTimer.Enabled = deltaX! = 0 || Delta! = 0; }}

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
