C＃的P / Invoke如何使用SendInput支持DirectX游戏来模拟一个按键事件 [英] C# p/Invoke How to simulate a keyPRESS event using SendInput for DirectX games

问题描述

我经常挣扎模拟各种机器人或其他自动化GUI程序的键盘按下事件

我已经成功地模拟使用的keydown事件：

 输入[] = kInput新的输入[1]; 
 kInput [J] .TYPE = SendInputEventType.InputKeyboard; 
 kInput [J] .mkhi.ki.wVk = 0; 
 kInput [J] .mkhi.ki.wScan =（USHORT）MapVirtualKey（（UINT）Keys.D5，0）; 
 kInput [J] .mkhi.ki.dwFlags = KeyboardEventFlags.SCANCODE; 
 kInput [J] .mkhi.ki.time = 0; 
 kInput [J] .mkhi.ki.dwExtraInfo = IntPtr.Zero; 
 SendInput（1，kInput，Marshal.SizeOf（typeof运算（输入）））; 
  

或

 输入[] = kInput新的输入[1]; 
 kInput [1] = .TYPE SendInputEventType.InputKeyboard; 
 kInput [1] .mkhi.ki.wVk ='5'; 
 kInput [1] .mkhi.ki.wScan = 0; 
 kInput [1] .mkhi.ki.dwFlags = 0; 
 kInput [1] .mkhi.ki.time = 0; 
 kInput [1] .mkhi.ki.dwExtraInfo = IntPtr.Zero; 
 SendInput（1，kInput，Marshal.SizeOf（typeof运算（输入）））; 
 
 
 <$ P $：使用
  

和KeyUp事件p> kInput [1] = .TYPE SendInputEventType.InputKeyboard;
kInput [1] .mkhi.ki.wVk = 0;
kInput [1] .mkhi.ki.wScan =（USHORT）MapVirtualKey（（UINT）Keys.D5，0）;
kInput [1] .mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP;
kInput [1] .mkhi.ki.time = 0;
kInput [1] .mkhi.ki.dwExtraInfo = IntPtr.Zero;
SendInput（1，kInput，Marshal.SizeOf（typeof运算（输入）））;


或

  kInput [1] = .TYPE SendInputEventType.InputKeyboard; 
 kInput [1] .mkhi.ki.wVk ='5'; 
 kInput [1] .mkhi.ki.wScan = 0; 
 kInput [1] .mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP; 
 kInput [1] .mkhi.ki.time = 0; 
 kInput [1] .mkhi.ki.dwExtraInfo = IntPtr.Zero; 
 SendInput（1，kInput，Marshal.SizeOf（typeof运算（输入）））; 
  

尽管我尝试两种为结合：

  //键，
输入kInput =新的输入[2]; 
 kInput [0] = .TYPE SendInputEventType.InputKeyboard; 
 kInput [0] .mkhi.ki.wVk = 0; 
 kInput [0] .mkhi.ki.wScan =（USHORT）MapVirtualKey（（UINT）Keys.D5，0）; 
 kInput [0] = .mkhi.ki.dwFlags KeyboardEventFlags.SCANCODE; 
 kInput [0] .mkhi.ki.time = 0; 
 kInput [0] = .mkhi.ki.dwExtraInfo IntPtr.Zero; 
 
 //重点高达
 kInput [1] = .TYPE SendInputEventType.InputKeyboard; 
 kInput [1] .mkhi.ki.wVk = 0; 
 kInput [1] .mkhi.ki.wScan =（USHORT）MapVirtualKey（（UINT）Keys.D5，0）; 
 kInput [1] .mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP; 
 kInput [1] .mkhi.ki.time = 0; 
 kInput [1] .mkhi.ki.dwExtraInfo = IntPtr.Zero; 
 
 // sendinput 
 SendInput（1，kInput，Marshal.SizeOf（typeof运算（INPUT）））; 
  

曾经有过不同程度的成功，我从来没有真正能够仿真一键保持/新闻事件，其中的支持DirectX（或其他3D）游戏会看到我的投入完全不一样的人带物理键盘会...

如何将之一，采用SendInput，模拟通过支持DirectX游戏中看到的按键/保持事件？

解决方案

要模拟键盘事件在DirectX游戏中，你需要包装的键盘驱动程序。我有同样的问题，也不这个方法（SendInput，SendKeys类）并不能帮助我。尝试使用此包装，对我来说这是成功的。

I've often struggled with simulating keyboard press events for various bots, or other GUI automating programs.

I've managed to simulate keydown events using:

INPUT[] kInput = new INPUT[1];
kInput[j].type = SendInputEventType.InputKeyboard;
kInput[j].mkhi.ki.wVk = 0;
kInput[j].mkhi.ki.wScan = (ushort) MapVirtualKey((uint) Keys.D5, 0);
kInput[j].mkhi.ki.dwFlags = KeyboardEventFlags.SCANCODE;
kInput[j].mkhi.ki.time = 0;
kInput[j].mkhi.ki.dwExtraInfo = IntPtr.Zero;
SendInput(1, kInput, Marshal.SizeOf(typeof(INPUT)));

OR

INPUT[] kInput = new INPUT[1];
kInput[1].type = SendInputEventType.InputKeyboard;
kInput[1].mkhi.ki.wVk = '5';
kInput[1].mkhi.ki.wScan = 0;
kInput[1].mkhi.ki.dwFlags = 0;
kInput[1].mkhi.ki.time = 0;
kInput[1].mkhi.ki.dwExtraInfo = IntPtr.Zero;
SendInput(1, kInput, Marshal.SizeOf(typeof(INPUT)));

and keyup events using:

kInput[1].type = SendInputEventType.InputKeyboard;
kInput[1].mkhi.ki.wVk = 0;
kInput[1].mkhi.ki.wScan = (ushort)MapVirtualKey((uint)Keys.D5, 0);
kInput[1].mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP;
kInput[1].mkhi.ki.time = 0;
kInput[1].mkhi.ki.dwExtraInfo = IntPtr.Zero;
SendInput(1, kInput, Marshal.SizeOf(typeof(INPUT)));

OR

kInput[1].type = SendInputEventType.InputKeyboard;
kInput[1].mkhi.ki.wVk = '5';
kInput[1].mkhi.ki.wScan = 0;
kInput[1].mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP;
kInput[1].mkhi.ki.time = 0;
kInput[1].mkhi.ki.dwExtraInfo = IntPtr.Zero;
SendInput(1, kInput, Marshal.SizeOf(typeof(INPUT)));

And while my attempts to combine the two as:

//key down
INPUT kInput = new INPUT[2];
kInput[0].type = SendInputEventType.InputKeyboard;
kInput[0].mkhi.ki.wVk = 0;
kInput[0].mkhi.ki.wScan = (ushort) MapVirtualKey((uint) Keys.D5, 0);
kInput[0].mkhi.ki.dwFlags = KeyboardEventFlags.SCANCODE;
kInput[0].mkhi.ki.time = 0;
kInput[0].mkhi.ki.dwExtraInfo = IntPtr.Zero;

//Key Up
kInput[1].type = SendInputEventType.InputKeyboard;
kInput[1].mkhi.ki.wVk = 0;
kInput[1].mkhi.ki.wScan = (ushort)MapVirtualKey((uint)Keys.D5, 0);
kInput[1].mkhi.ki.dwFlags = KeyboardEventFlags.KEYUP;
kInput[1].mkhi.ki.time = 0;
kInput[1].mkhi.ki.dwExtraInfo = IntPtr.Zero;

//sendinput
SendInput(1, kInput, Marshal.SizeOf(typeof(INPUT)));

Have had varying degrees of success, I was never actually capable of emulating a key hold/press event where a DirectX (or other 3d) game would see my input in quite the way a human with a physical keyboard would...

How would one, using SendInput, emulate a key press/hold event as seen by a DirectX game?

解决方案

To simulate keyboard events in directX games you need wrapper for a keyboard driver. I had the same issue, and neither of this methods (SendInput, SendKeys class) doesn't help me. Try to use this wrapper, to me it was successfully.
