Windows Touch Input的疑难问题
1、问题：我处理WM_TOUCH消息后，没有得到boundary feedback（边界反馈）#ifndef WINVER // Specify that the minimum required platform is Windows 7.
#define WINVER 0x0601
#endif#ifndef WM_TOUCH
#define WM_TOUCH 0x0240 // 自定义多点触摸消息：来自MSDN
#endifPOINT ptInput;
if (GetTouchInputInfo((HTOUCHINPUT)lParam, cInputs, pInputs, sizeof(TOUCHINPUT)))
{
for (int i=0; i < static_cast<INT>(cInputs); i++)
{
TOUCHINPUT ti = pInputs[i];
if (ti.dwID != 0)
{
// Do something with your touch input handle.
ptInput.x = TOUCH_COORD_TO_PIXEL(ti.x);
ptInput.y = TOUCH_COORD_TO_PIXEL(ti.y);
ScreenToClient(hWnd, &ptInput);
points[ti.dwID][0] = ptInput.x;
points[ti.dwID][1] = ptInput.y;
}
}
}// The message map.

}NID_READY 0x00000080 输入设备准备好输入了
检查NID_* 值是一种很有效的检查用户的设备支持touch pen or no-table input的能力。例如，如果你有一个动态的UI，想要动态地配置一些东西，你可以检查NID_INTEGRATED_TOUCH，NID_MULTITOUCH，在用户第一次运行你的应用程序的时候获得最小的上表中的值。
对于SM_GETSYSTEMMETRICS 有一些固有的限制，不支持即插即用，当用这个函数的时候应该注意这一点。
第二步：注册touch窗口
应用程序必须先注册才能收到多点触摸消息，通过函数RegisterTouchWindow函数，退出时必须卸载，通过函数UnRegisterTouchWindow函数。BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
