更新MQL4 600和命名管道
sksyen:
谢谢你的回复，我为没有将SRC作为文件粘贴而道歉。
关于你的回答，这是否意味着我只需要将命名的管道 "A "的引用改为 "W"？我试着查找了一些关于这个问题的帖子，但没有找到--非常感谢您的帮助。再次感谢。
这不是把源码作为文件粘贴，而是使用SRC工具把代码放在论坛这里。 如何使用SRC按钮。( 由 "RaptorUK "提供)
这里有几个关于广义版本的函数的类似困境的参考资料。
谢谢你。 服务器端现在能够在更新命名的管道"A "到 "W "后捕捉到呼叫计数。 然而，从MT4的另一个实例来看，它在接收信息的输入方面似乎有困难。 我已经在接收端将名称管道更新为 "W"，但由于某种原因，它仍然无法提取数据。 有什么想法吗？ 请看下面的接收端代码。

"sksyen"，你能不能修改你的原帖，把代码放在SRC部分。如果有一个版主去看这个，他们会删除帖子的那一部分，并要求你无论如何都要好好做。所以，在你不得不再次去寻找代码粘贴之前，现在就做吧。
在最新发布的MT4中，我也遇到了命名管道 的问题
我把WaitNamedPipeA改为WaitNamedPipeW，现在可以工作了
f (!WaitNamedPipeW( FullPipeName, 1)) { Comment(TimeToStr(TimeLocal(), TIME_DATE|TIME_MINUTES|TIME_SECONDS) + " " + PipeName + " not available"); Sleep(1000); continue; }
但当我使用CreateFileA或CreateFileW时，两个调用都会永久挂起。
PipeHandle = CreateFileA（FullPipeName, GenericRead, 0, NULL, OPEN_EXISTING, 0, NULL）。
有什么想法/解决方案吗？

你好。
在最近的更新之后，我现在无法从我的MT4终端的一个实例中捕获调用计数，并将其转发到另一个MT4上。 你能告诉我在更新中发生了什么变化，导致这个问题吗？ 以下是代码，在Build 509中可以继续正常工作，但在最近的更新后就不行了。
