問題描述

我在這里遇到了一個嚴(yán)重的問題.我需要通過 C++ 執(zhí)行 CMD 命令行而不顯示控制臺窗口.因此我不能使用 system(cmd)，因為窗口會顯示.

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.

我已經(jīng)嘗試過 winExec(cmd, SW_HIDE)，但這也不起作用.CreateProcess 是我嘗試過的另一個.但是，這是用于運行程序或批處理文件.

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.

我最終嘗試了 ShellExecute:

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

有人能看出上面的代碼有什么問題嗎?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.

我真的需要一些幫助.什么都沒有發(fā)現(xiàn)，我已經(jīng)嘗試了很長一段時間.任何人都可以提供的任何建議都會很棒:)

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 :)

推薦答案

將輸出重定向到您自己的管道是一個更簡潔的解決方案，因為它避免了創(chuàng)建輸出文件，但這工作正常:

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);

您沒有看到 cmd 窗口，并且輸出按預(yù)期重定向.

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

您的代碼可能失敗了(除了 /C 之外)，因為您將路徑指定為 "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".
