函数说明：VOID keybd_event( BYTE bVk, BYTE bScan, DWORD dwFlags, DWORD dwExtraInfo );ParametersbVk[in] Specifies a virtual-key code. The code must be a value in the range 1 to 254. bScan[in] Specifies a hardware scan code for the key. dwFlags[in] Specifies various aspects of function operation. An application can use any combination of the following predefined constant values to set the flags. Value Description KEYEVENTF_KEYUP If specified, the key is being released. If not specified, the key is being depressed. KEYEVENTF_SILENT If specified, a keystroke is simulated, but no clicking sound is made. dwExtraInfo[in] Specifies an additional 32-bit value associated with the key stroke. Return ValuesNone.ResWhen keyboard input is disabled with EnableHardwareKeyboard(FALSE), you can simulate keyboard input using keybd_event.Although keybd_event passes an OEM-dependent hardware scan code to the system, applications should not use the scan code. The system converts scan codes to virtual-key codes internally and clears the up/down bit in the scan code before passing it to applications. An application can simulate a press of the PRINTSCREEN key in order to obtain a screen snapshot and save it to the clipboard. To do this, call keybd_event with the bVk parameter set to VK_SNAPSHOT, and the bScan parameter set to 0 for a snapshot of the full screen or set bScan to 1 for a snapshot of the active window.
