获取IP地址并根据IP映射驱动器 [英] get the ip address and map a drive according to IP
问题描述
我知道我可以使用ipconfig.exe来获取我的IP地址，
的情况是我需要自动执行此过程。
我需要编写一个DOS程序，它发出一个运行IPCONFIG的命令来获取IP地址，然后发出net use命令来映射
网络上的驱动器。
我知道你可以使用系统
system（''command.com / c ipcoinfig.exe"）
或
system（''command.com ipcoinfig.exe"）
启动shell，但是如何从捕获IP地址然后从IP中捕获输出？
我可以知道我需要映射的网络上的哪个服务器
到，所以我可以发出另一个
系统（command.com net use z：\\ xyzserver \ myshare mypw / User：me）
来映射驱动器，我还需要检查网络使用是否正常工作。
谢谢！

你几乎当然不需要显式运行command.com，因为
系统函数使用shell运行指定的命令。 />
system（" ipcoinfig.exe"）
另请复制并粘贴实际代码。因为你在
使用了单引号，所以它显然不是你试过的代码。
启动shell，但是如何从中捕获输出？
使用某种特定于系统的方法。在DOS或Windows组中询问
的详细信息。他们可能会告诉你，有一个API可以给你更可靠的信息。

与以前相同的评论。另外你需要考虑/字符
在C字符串中有特殊含义所以你可能想要... //用户：我
另外，你确定C程序是合适的吗？这听起来像是一个脚本语言的工作。
我们没有涵盖字符串传递给系统的细节意味着什么
因为它们是特定于系统的。我们也没有涵盖Windows，* nix和其他系统用于网络的API。我们不会覆盖
替代方法来调用外部程序，这些方法可以为您提供更多直接访问程序调用输出的内容。

Hi, I know I can use ipconfig.exe is DOS to get my IP address, the
situation is I need to automat this process.
I need to write a DOS program which issue a command to run IPCONFIG to
get the IP address then issue a net use command to map a drive on the
network.
I know you can use system
system (''command.com /c ipcoinfig.exe")
or
system (''command.com ipcoinfig.exe")
the start the shell, but how do I capture the output from it?
after I capture the IP address then from the IP I can know which server
on the network I need to map to, so I can issue another
system("command.com net use z: \\xyzserver\myshare mypw /User:me")
to map the drive, I need to also check if the net use worked correctly.
Thanks!

I know you can use system
system (''command.com /c ipcoinfig.exe")
or
system (''command.com ipcoinfig.exe")You almost certainly don''t need to explicitly run command.com since the
system function runs the specified command using the shell.
system("ipcoinfig.exe")
Also please copy and paste actual code. Since you used a single quote at
the start it obviously was not the code you had tried.
the start the shell, but how do I capture the output from it?Using some system specific method. Ask in a DOS or Windows group for the
details. They will probably tell you that there is an API that can give
you the information far more reliably.
after I capture the IP address then from the IP I can know which server
on the network I need to map to, so I can issue another
system("command.com net use z: \\xyzserver\myshare mypw /User:me")
to map the drive, I need to also check if the net use worked correctly.Same comments as before. Also you need to consider that the / character
has special meaning in C strings so you probably wanted "... //User:me"
Also, are you sure a C program is the appropriate thing? This sounds to
me more like a job for a scripting language.
We don''t cover the details of what the strings passed to system mean
since they are system specific. We also don''t cover the APIs that
Windows, *nix and other systems have for networking. Not do we cover the
alternative methods of invoking external programs that give you more
direct access to what the program invoked outputs.
