Отправить ПРОБЕЛ на другое приложение

Question

У меня есть проблема с отправкой ПРОБЕЛА в другое приложение (игра)

В то время как этот код работает для ввода (даже в игре) она не имитирует key_pressed действия. Я использую C# с .Net Framework 4.5.

Process p = Process.GetProcessesByName("game").FirstOrDefault(); 
if (p != null) 
{ 
    IntPtr h = p.MainWindowHandle; 

    SetForegroundWindow(h); 
    SendKeys.SendWait("{ }"); 
} 

Я попытался с:

SendKeys.SendWait("{ }"); 

SendKeys.SendWait(" "); 

Если я выбираю Блокнот он работает, он также работает, если у меня есть фокус (в игре) на некотором входе, например, textbox chat, но когда в игре мне предлагается нажать пробел (нажмите пробел, чтобы продолжить), это не сработает.

Проблема в том, что в большинстве игр используется DirectInput. Таким образом, стандартные сообщения Windows для управления ключами обойдены. Вам нужно будет использовать коды DirectX. Вот код из моего приложения для распознавания голоса, который отправляет ключи к играм, которые могут вам помочь:

using System; 
using System.Runtime.InteropServices; 

namespace BlueMercs.Core.Services 
{ 
    [StructLayout(LayoutKind.Sequential)] 
    struct MouseInput 
    { 
     public int dx; 
     public int dy; 
     public int mouseData; 
     public int dwFlags; 
     public int time; 
     public IntPtr dwExtraInfo; 
    } 

    [StructLayout(LayoutKind.Sequential)] 
    struct KeyboardInput 
    { 
     public short wVk;  //Virtual KeyCode (not needed here) 
     public short wScan; //Directx Keycode 
     public int dwFlags; //This tells you what is use (Keyup, Keydown..) 
     public int time; 
     public IntPtr dwExtraInfo; 
    } 

    [StructLayout(LayoutKind.Sequential)] 
    struct HardwareInput 
    { 
     public int uMsg; 
     public short wParamL; 
     public short wParamH; 
    } 

    [StructLayout(LayoutKind.Explicit)] 
    struct Input 
    { 
     [FieldOffset(0)] 
     public int type; 
     [FieldOffset(4)] 
     public MouseInput mi; 
     [FieldOffset(4)] 
     public KeyboardInput ki; 
     [FieldOffset(4)] 
     public HardwareInput hi; 
    } 

    [Flags] 
    public enum KeyFlag 
    {  
     KeyDown = 0x0000, 
     ExtendedKey = 0x0001, 
     KeyUp = 0x0002, 
     UniCode = 0x0004, 
     ScanCode = 0x0008 
    } 

    public static class WindowsMessageService 
    { 
     [DllImport("user32.dll")] 
     private static extern UInt32 SendInput(UInt32 nInputs,[MarshalAs(UnmanagedType.LPArray, SizeConst = 1)] Input[] pInputs, Int32 cbSize); 

     public static void SendInput(short keycode, KeyFlag keyFlag) 
     { 
      var inputData = new Input[1]; 

      inputData[0].type = 1; 
      inputData[0].ki.wScan = keycode; 
      inputData[0].ki.dwFlags = (int)keyFlag; 
      inputData[0].ki.time = 0; 
      inputData[0].ki.dwExtraInfo = IntPtr.Zero; 

      SendInput(1, inputData, Marshal.SizeOf(typeof(Input))); 
     } 

     public static void SendKey(short keyCode, KeyFlag keyFlag) 
     { 
      SendInput(keyCode, keyFlag | KeyFlag.ScanCode); 
     } 
    } 
} 



    public class DirectxKey

     public int Decimal { get; set; } 
     public short Hex { get; set; }
