您已经问过这个问题.再重复一次完全相同的问题是没有意义的-实际上，它使人们感到烦恼，因此您不太可能获得有用的答案.

另外，请问您输入问题的屏幕上的第4项，内容为:-

4.使问题尽可能简洁.如果您必须包含代码，请包含最小的代码片段-不要转储整个代码库.


期望繁忙的人们在您所说的所有代码不起作用时会经历所有这些代码，这是很多事情–它以什么方式不起作用".如果您不能将问题缩小到更小的代码部分，则至少要更详细地描述问题(最好同时执行).

如果可以的话，我相信有人会为您提供有关此问题的帮助. :thumbsup:

祝您好运:)

You have already asked this question. There is no point in repeating the exact same question again - in fact it annoys people so you are less likely to get a usefull answer.

Also, may I refer you to item 4 on the screen where you entered your questions, it says:-

4. Keep the question as concise as possible. If you have to include code, include the smallest snippet of code you can - do not dump your entire codebase.


It is a lot to expect busy people to go through all this code when all you say is it is not working - in what way is it ''not working''. If you cannot narrow the problem down to a smaller peice of code at least describe the problem in greater detail (preferaby do both).

If you can do that I am sure someone will be able to give you some help with this problem. :thumbsup:

Best of Luck :)
