我在这里有一个严重的问题。 我需要通过C ++执行CMD命令行，而不显示控制台窗口。 所以我不能使用system(cmd) ，因为窗口会显示。
我已经尝试winExec(cmd, SW_HIDE) ，但这也不起作用。 CreateProcess是我尝试的另一个。 但是，这是用于运行程序或batch file。
我已经结束了尝试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问题吗？ 我已经使用SW_SHOWNORMAL直到我知道这个工程。
我真的需要一些帮助。 没有任何东西显露出来，我一直在尝试一段时间。 任何人可以给的build议将是伟大的:)
将输出重定向到你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，但是这个工作正常：
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。
您的代码可能会失败（除了/C之外），因为您将路径指定为"c:\projects\b"而不是"c:\\projects\\b" 。
您应该使用cmd.exe上的CreateProcess和/C参数来隧道ipconfig命令。 >本身在命令行上不起作用。 您必须以编程方式重定向stdout 。
这里是我的DosExec函数的实现，它允许（静默）执行任何DOS命令，并以unicode字符串的形式检索生成的输出。

我有一个类似的程序（windows7和10测试）在github上
https://github.com/vlsireddy/remwin/tree/master/remwin
这是服务器程序
这不显示“控制台窗口”没有人需要执行cmd.exe手动命令remwin.exe可以在后台运行，其瘦服务器程序
