如何在Win32 API中生成击键组合？

Question

我有此代码模拟窗口键的按压。但是，我将如何按下窗口+D键，从本质上显示桌面。

void ShowDesktop(void)
{


  // Simulate a key press
     keybd_event( VK_LWIN,
                  0x5B,
                  KEYEVENTF_EXTENDEDKEY | 0,
                  0 );

  // Simulate a key release
     keybd_event( VK_LWIN,
                  0x5B,
                  KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
                  0);

}

Answer 1

你必须打电话 keybd_event 具有虚拟钥匙值和硬件扫描代码的功能 d 获得此值的关键您可以使用 MapVirtualKey 功能。

尝试此样本。

//simulate the Win key press
    keybd_event(VK_LWIN, 0x5B, 0, 0);
//simulate the 'D' key press,the 0x44 is the Virtual key value for the 'D' key, the 0x20 vaue is the hardware scan code for the 'D' key
    keybd_event(0x44, 0x20, 0, 0);
//simulate the 'D' key release
    keybd_event(0x44, 0x20, KEYEVENTF_KEYUP, 0);
//simulate the Win key release
    keybd_event(VK_LWIN, 0x5B, KEYEVENTF_KEYUP, 0);
