SendInput() not equal to pressing key manually on keyboard in C++?

Question

I wanted to write a c++ code to emulate pressing a keyboard key \"A\":

// Set up a generic keyboard event.
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = 0; // hard         


        

Answer 1

You often need to set the scan code:

// Set up a generic keyboard event.
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = MapVirtualKey(code, MAPVK_VK_TO_VSC); // hardware scan code for key
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;

// Press the "..." key
ip.ki.wVk = code; // virtual-key code for the "a" key
ip.ki.dwFlags = 0; // 0 for key press
SendInput(1, &ip, sizeof(INPUT));

And building an array as IInspectable suggests is also definitely the way to go.
