不支持" FingerRecognition "。是否存在同时限制支持的触摸点的解决方案（如10）？

说："不幸的是我的触摸设备（21"多点触控）不支持" FingerRecognition "我猜您正在使用W7和Surface SDK？

如果限制数量 触摸是你的目标，我猜你可以抓住事件处理程序以进行上一次触摸并构建一个捕获触摸列表。然后，一旦您的触摸计数达到最大值，您就可以忽略传入的触摸。

如果您进入该路径，则需要在触摸被移除时保持列表同步。 / p>

希望它掌握

Hi,

I've got a serious situation with my own application (.NET 4.0 WPF) with performance. While someone is touching screen all surface of his/her hand,  an application is freezing for a moment. Unfortunately my touch device (21" multitouch) do not support "FingerRecognition". Is exist a solution to limitation of supported touch points at the same time (like 10) ?

Hi,

By saying :"Unfortunately my touch device (21" multitouch) do not support "FingerRecognition" I guess you are working on W7 and Surface SDK?

If limiting the number of  touch is your goal, I guess you can catch the event handler for previous touch down and build out of this a list of capture touch. Then once your touch count has reach your max your simply ignore incoming touch.

If you go in that path, you will need to keep your list in synchrone as well when touch gets removed.

hope it helsp
