Usage Guide

Initialize Driver

// Load driver
LoadNTDriver("lykeys", "lykeys.sys");

// Set handle
SetHandle();

// Check status
DEVICE_STATUS status = GetDriverStatus();
if (status == DEVICE_STATUS_READY) {
    // Driver is ready
}

Keyboard Operation

// Press A key
KeyDown(0x41);

// Wait for a while
Sleep(100);

// Release A key
KeyUp(0x41);

Mouse Operation

// Move mouse
MouseMoveRELATIVE(10, 20);

// Click left button
MouseLeftButtonDown();
Sleep(50);
MouseLeftButtonUp();

// Scroll mouse wheel
MouseWheelUp(120);

Notes

1. You must call LoadNTDriver to load the driver before use
2. After loading the driver, you need to call SetHandle to get the device handle
3. It's recommended to check the driver status with GetDriverStatus before all operations
4. Call UnloadNTDriver to unload the driver before the program exits
5. Mouse movement coordinates use screen coordinate system (origin at the top-left corner)
6. Keyboard operations use Windows Virtual-Key Codes
