首先是,头文件必须包含以下两个:
#include <winable.h>
#include <atlconv.h>
前者是SendInput函数要用到,后者是字符串转换的时候要用到。
void SendAscii(wchar_t data, BOOL shift)
{
INPUT input[2];
memset(input, 0, 2 * sizeof(INPUT));
if (shift)
{
input[0].type = INPUT_KEYBOARD;
input[0].ki.wVk = VK_SHIFT;
SendInput(1, input, sizeof(INPUT));
}
input[0].type = INPUT_KEYBOARD;
input[0].ki.wVk = data;
input[1].type = INPUT_KEYBOARD;
input[1].ki.wVk = data;
input[1].ki.dwFlags = KEYEVENTF_KEYUP;
SendInput(2, input, sizeof(INPUT));
if (shift)
{
input[0].type = INPUT_KEYBOARD;
input[0].ki.wVk = VK_SHIFT;
input[0].ki.dwFlags = KEYEVENTF_KEYUP;
SendInput(1, input, sizeof(INPUT));
}
}
void SendUnicode(wchar_t data)
{
INPUT input[2];
memset(input, 0, 2 * sizeof(INPUT));
input[0].type = INPUT_KEYBOARD;
input[0].ki.wVk = 0;
input[0].ki.wScan = data;
input[0].ki.dwFlags = 0x4;//KEYEVENTF_UNICODE;
input[1].type = INPUT_KEYBOARD;
input[1].ki.wVk = 0;
input[1].ki.wScan = data;
input[1].ki.dwFlags = KEYEVENTF_KEYUP | 0x4;//KEYEVENTF_UNICODE;
SendInput(2, input, sizeof(INPUT));
}
//为方便使用,下面这个函数包装了前两个函数。
void SendKeys(CString msg)
{
short vk;
BOOL shift;
USES_CONVERSION;
wchar_t* data = T2W(msg.GetBuffer(0));
int len = wcslen(data);
for(int i=0;i<len;i++)
{
if (data[i]>=0 && data[i]<256) //ascii字符
{
vk = VkKeyScanW(data[i]);
if (vk == -1)
{
SendUnicode(data[i]);
}
else
{
if (vk < 0)
{
vk = ~vk + 0x1;
}
shift = vk >> 8 & 0x1;
if (GetKeyState(VK_CAPITAL) & 0x1)
{
if (data[i]>='a' && data[i]<='z' || data[i]>='A' && data[i]<='Z')
{
shift = !shift;
}
}
SendAscii(vk & 0xFF, shift);
}
}
else //unicode字符
{
SendUnicode(data[i]);
}
}
}
直接调用SendKeys函数就可以在当前光标的位置自动输入指定的字符串,下面的例子演示了如何自动打开记事本程序并输入一段话:
void CSendInputDlg::OnTest()
{
ShellExecute(NULL, NULL, "notepad.exe", NULL, NULL, SW_SHOWNORMAL);
Sleep(500); //为了确保记事本程序打开完毕,稍等片刻
CWnd *pWnd = FindWindow(NULL, "无标题 - 记事本");
if (pWnd)
{
pWnd->SetForegroundWindow();
SendKeys("我是sway,我爱中国!\nI love China!\nEmail: \b\b");
}
}
