windows C system call with spaces in command
提问by myforwik
I cannot make system calls with spaces in the names and parameters. For example:
我无法使用名称和参数中的空格进行系统调用。例如：
system("c:\program files\something\example.exe c:\my files\example.txt");
I have tried escaping in every way I know how, and NOTHING works. I have tried:
我尝试过以我知道的各种方式逃避，但没有任何效果。我试过了：
system("\"c:\program files\something\example.exe\" \"c:\my files\example.txt\"");
and
和
system("c:\program^ files\something\example.exe c:\my^ files\example.txt");
Neither work. I still get 'c:\program' is not a recongnised internal or external command
都不工作。我仍然得到 'c:\program' is not a recongnised internal or external command
This is really driving me mad... I need to call and pass parameters that have spaces in them. I cannot use the short notation for reasons I won't go into.
这真的让我发疯......我需要调用并传递其中包含空格的参数。由于我不会讨论的原因，我不能使用短符号。
I have tried with ' quotes instead of " quotes, still doesn't work. I have tried putting quotes around the whole thing and quotes around the spaces and that doesn't work.
我试过用 ' 引号代替 " 引号，仍然不起作用。我试过在整个事物周围加上引号，在空格周围加上引号，但那不起作用。
Does anyone know how to do it properly?
有谁知道如何正确地做到这一点？

Edit:OK, figured it out by stepping into the system()call: you need an extra set of quotes around the whole thing due the fact that it internally calls cmd /cyourinput
编辑：好的，通过进入system()调用来解决这个问题：由于它在内部调用cmd /c yourinput，因此整个事情需要一组额外的引号
So this works for me:
所以这对我有用：
system("\"\"c:\program files\internet explorer\iexplore.exe\" \"www.stackoverflow.com\"\"");
A bit of a mess, isn't it?
有点乱，不是吗？
