C ++执行DOS命令 [英] C++ Executing DOS Commands

问题描述

这里有严重的问题。需要执行正常的DOS命令（在Windows中），而CMD窗口不显示在C ++中。因此我不能使用 system（cmd）; （窗口会显示）

Serious Problem im having here. Need to execute normal DOS Commands (in windows) without the CMD window displaying in C++. Therefore i can not use system(cmd); (As the window will display)

c $ c> winExec（cmd，SW_HIDE）这也不工作。 CreateProccess 是另一个我尝试，但是这是运行程序或批处理文件。

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

code> ShellExecute（）

I have resulted in trying ShellExecute()

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

任何人都可以看到上面的代码有什么不对吗？我已经使用 SW_SHOWNORMAL ，直到我知道这个工作。

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。没有什么是光明的，我一直在尝试了一段时间。任何人都可以给出的任何建议都是巨大的：）

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整洁的解决方案，输出文件，但是工作正常：

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.

你的代码可能失败了（除了 / C ），因为你指定路径为c ：\projects\b而不是c：\\projects\\b。

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