SendInput模拟键盘操作

#include <windows.h>

int main()
{
	HWND parentHwnd, childHwnd;
	INPUT input[4];
	parentHwnd = FindWindow(TEXT("Notepad"), NULL);
	if (parentHwnd)
	{
		childHwnd = FindWindowEx(parentHwnd, NULL, TEXT("Edit"), NULL);
		if (childHwnd)
		{
			for (int i = 0; i < 10; i++)
			{
				SendMessage(childHwnd, WM_CHAR, 'A', 0);
			}

			SetForegroundWindow(parentHwnd);

			//CTRL+S
			memset(input, 0, sizeof(input));
			input[0].type = input[1].type = input[2].type = input[3].type = INPUT_KEYBOARD;
			input[0].ki.wVk = input[2].ki.wVk = VK_CONTROL;
			input[1].ki.wVk = input[3].ki.wVk = 0x53;
			input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;
			SendInput(4, input, sizeof(INPUT));

			//ALT+F4
			memset(input, 0, sizeof(input));
			input[0].type = input[1].type = input[2].type = input[3].type = INPUT_KEYBOARD;
			input[0].ki.wVk = input[2].ki.wVk = VK_MENU;
			input[1].ki.wVk = input[3].ki.wVk = VK_F4;
			input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;
			SendInput(4, input, sizeof(INPUT));

		}
	}
	return 0;
}

/*

/*

while (1)
{
Sleep(1000);
GetCursorPos(&pt);

实现操作：向已经打开的记事本写入数据，保存(CTRL+S)，关闭(ALT+F4)。

尝试用SendMessage发送组合键，没有得到解决办法。

如果我们获取QQ窗口的HWND，那么我们就可以自动发消息了。

int main()
{
	HWND hwndTX, hwndConsole;
	INPUT input[4];
	hwndConsole = GetConsoleWindow();
	hwndTX = FindWindow(TEXT("TXGuiFoundation"), TEXT("N3verL4nd"));
	if (hwndTX != NULL)
	{
		for (int i = 0; i < 10; i++)
		{
			SendMessage(hwndTX, WM_CHAR, 'A', 0);
		}

		SetForegroundWindow(hwndTX);
		memset(input, 0, sizeof(input));
		input[0].type = input[1].type = input[2].type = input[3].type = INPUT_KEYBOARD;
		input[0].ki.wVk = input[2].ki.wVk = VK_MENU;
		input[1].ki.wVk = input[3].ki.wVk = 0x53;
		input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;
		SendInput(4, input, sizeof(INPUT));
		SetForegroundWindow(hwndConsole);
	}
	else
	{
		puts("not found");
	}
	return 0;
}
