基于WinIO 3.0实现驱动级键盘模拟输入
一个业务场景需要使用驱动级的键盘模拟，折腾了2天，总结一下，为后人节省时间。
限制条件：
1.需要真实PC机，虚拟机不行
2.仅支持PS/2 键盘（指外接键盘，笔记本直接使用是没问题的）
实现：
关于WinIO没啥好说的，自行查阅吧。
直接上可执行代码，注意红色注释部分，网上很多资料这几个不对导致不能有正确结果
测试程序里扣出来的，请先行初始化调用InitializeWinIo();
#define KBC_CMD 0x64
#define KBC_DATA 0x60
void KBCWait4IBE()
{
DWORD dwVal=0;
do
{
GetPortVal(KBC_CMD,&dwVal,1);
}
while(dwVal & 0x00000002); //其他条件均不正确
}
void KEY_DOWN(int vk_in)
{
bool bRet = false;
unsigned int myscancode;
myscancode=MapVirtualKey(BYTE(vk_in),0);
KBCWait4IBE();
bRet = SetPortVal(KBC_CMD,0xD2,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_DATA,0xE2,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_CMD,0xD2,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_DATA,myscancode,1);
}
void KEY_UP(int vk_in)
{
bool bRet = false;
unsigned myscancode;
myscancode=MapVirtualKey(BYTE(vk_in),0);
KBCWait4IBE();
bRet = SetPortVal(KBC_CMD,0xD2,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_DATA,0xE0,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_CMD,0xD2,1);
KBCWait4IBE();
bRet = SetPortVal(KBC_DATA,(myscancode|0x80),1); //此处需要与上0x80
}
void Key_Press(int vk_in)
{
// sti() ;
KEY_DOWN(vk_in);
Sleep(150);
KEY_UP(vk_in);
Sleep(150);
}
void InputString(CString &strInput)
{
int nLen = strInput.GetLength();
for (int i = 0; i < nLen; i++)
{
short nKey = VkKeyScan(strInput.GetAt(i)); //注：由ASCII码转成按键码
bool bShift = (nKey & 0x100); //shift键是否按下检查
long n = GetKeyState(VK_CAPITAL); //Caps键是否按下检查
Key_Press(nKey);
}
}
void CWinIOTestDlg::OnButton1()
{
// TODO: Add your control notification handler code here
CString strInput;
CWnd* pWnd =
GetDlgItem( IDC_EDIT1 );
pWnd->GetWindowText(strInput);
Sleep(4000); //可以不用，我测试时留时间给自己切换窗口用的
InputString(strInput);
}
void CWinIOTestDlg::OnCancel()
{
// TODO: Add extra cleanup here
ShutdownWinIo();
CDialog::OnCancel();
}
另WinIO 3.0的32位系统代码有点问题，在某些密码输入控件下输入会抛特权指令异常（privileged instruction）
解决方法也很简单（自己找解决办法搞了一天），修改WinIO代码为如下所示，重新编译生成DLL即可
