在Visual Basic 6中读取Shell程序的标准输出 [英] Shell process' standard output reading in Visual Basic 6

问题描述

首先，让我说我不是Visual Basic 6专家...

First, let me say that I'm not a Visual Basic 6 expert...

我的需要是

• 从VB6客户端代码启动一个外部.exe文件
• 等待过程完成，并在执行过程中即时"读取来自其标准输出的消息(以便我可以将其打印在文本文件化的小部件或类似部件上).

我想知道是否有可能在VB6中做到这一点……在互联网上进行了长时间的搜索之后，我什么都没想到.找到了许多有关如何使用Shell函数的示例，但似乎迫使我在进程执行结束后立即全部读取标准输出，但是我想在进程中轮询新鲜"消息可用.

I'm wondering if it is even possible to do that in VB6...after a long search on the Internet I didn't come up with anything. Found a lot of examples of how to use the Shell function, but it seems to force me to read the stdout all at once when the process' execution is over, but I want to poll the process for "fresh" messages as they become available.

任何代码段/建议/引用都非常感谢.

Any code snippets/suggestions/references are really appreciated.

提前谢谢！

推荐答案

使用CreatePipe()创建可传递给CreateProcess()的匿名管道. 然后，您可以根据需要从该管道读取(使用轮询或重叠/异步I/O.

Use CreatePipe() to create an anonymous pipe that you can pass to CreateProcess(). You can then read from this pipe as required (either using polling or overlapped/async I/O.

这应该为您提供足够的信息以找到一个很好的例子.

This should give you enough info to find a good example.
