There is SendInputfunction that can generate keystrokes and other kinds of input. I have used to create application similar to virtual keyboards.
有SendInput能产生击键和其他类型的输入的功能。我曾经创建过类似于虚拟键盘的应用程序。
Example using Unicode:
使用 Unicode 的示例：
// This may be needed
// #define _WIN32_WINNT 0x0501
#include <windows.h>
#include <winuser.h>
void pressKey(WORD a_unicode)
{
KEYBDINPUT kbinput;
ZeroMemory(&kbinput, sizeof(kbinput));
kbinput.wScan = a_unicode;
kbinput.dwFlags = KEYEVENTF_UNICODE;
kbinput.time = 0;
INPUT input;
ZeroMemory(&input, sizeof(input));
input.type = INPUT_KEYBOARD;
input.ki = kbinput;
SendInput(1, &input, sizeof(input));
}
