C++ 执行 CMD 命令

问题描述

我在这里遇到了一个严重的问题.我需要通过 C++ 执行 CMD 命令行而不显示控制台窗口.因此我不能使用 system(cmd)，因为窗口会显示.

I'm having a serious problem here. I need to execute a CMD command line via C++ without the console window displaying. Therefore I cannot use system(cmd), since the window will display.

我已经尝试过 winExec(cmd, SW_HIDE)，但这也不起作用.CreateProcess 是我尝试过的另一个.但是，这是用于运行程序或批处理文件.

I have tried winExec(cmd, SW_HIDE), but this does not work either. CreateProcess is another one I tried. However, this is for running programs or batch files.

我最终尝试了 ShellExecute:

ShellExecute( NULL, "open",
    "cmd.exe",
    "ipconfig > myfile.txt",
    "c:projects",
    SW_SHOWNORMAL
);

有人能看出上面的代码有什么问题吗?我一直在使用 SW_SHOWNORMAL 直到我知道它有效.

Can anyone see anything wrong with the above code? I have used SW_SHOWNORMAL until I know this works.

我真的需要一些帮助.什么都没有发现，我已经尝试了很长一段时间.任何人都可以提供的任何建议都会很棒:)

I really need some help with this. Nothing has come to light, and I have been trying for quite a while. Any advice anyone could give would be great :)

推荐答案

将输出重定向到您自己的管道是一个更简洁的解决方案，因为它避免了创建输出文件，但这工作正常:

Redirecting the output to your own pipe is a tidier solution because it avoids creating the output file, but this works fine:

ShellExecute(0, "open", "cmd.exe", "/C ipconfig > out.txt", 0, SW_HIDE);

您没有看到 cmd 窗口，并且输出按预期重定向.

You don't see the cmd window and the output is redirected as expected.

您的代码可能失败了(除了 /C 之外)，因为您将路径指定为 "c:projects" 而不是 "c:\projects\b".

Your code is probably failing (apart from the /C thing) because you specify the path as "c:projects" rather than "c:\projects\b".
