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

问题描述

我在这里遇到严重问题。我需要通过C ++执行CMD命令行而不显示控制台窗口。因此，由于窗口将显示，因此我不能使用 system（cmd）。

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.

我尝试了 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的。

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\b",
    SW_SHOWNORMAL
);

有人可以看到上面的代码有问题吗？我一直使用 SW_SHOWNORMAL 直到知道这可行。

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。没有发现任何问题，并且我已经尝试了一段时间。任何人都可以给出的任何建议都很棒：）

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整洁的解决方案，因为它避免了创建输出文件，但这可以正常工作：

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，并且输出已按预期重定向。

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 外），因为您将路径指定为 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".
