You could also check _popen (stdio.h) for console applications (only).

To create a Windows application that redirects input and output, see Creating a Child Process with Redirected Input and Output in the Windows SDK.

上传多次上传不了;这是个chm格式的,看起来比PDF的要好一些。

是不是太大了,压缩一下吧

桥接模式就相当于你的主机是一个HUB,你的虚拟机只要配置家里或公司内网IP和网关及DNS就可以直接上网。你自己主机也自然能正常上网。

恩,这下理解了
我现在的虚拟机都是桥接模式的

换句话讲,是不是可以理解为
“现在性能还不错,主要原因是由于只分析特定端口造成的” 这个意思?

偶也觉得是这么个意思

nf_conntrack_ftp 是否可以监听任意端口数据?

应该会有吧,你可以看看/etc/skel中的内容以作参考。
另外,也要看你为用户设置使用了什么shell。

A normalized database will, in addition to your points, standardize the naming of the cities. However, then you need to populate your city table with all the cities in the world. Otherwise, you'll end up with something like New York and New-York.

Unless you are planning on having city information beyond just the name (e.g. size, geo-coordinates, etc), I say stick with string city names. If your code is good, you'll be able to normalize if ever the need comes up.

Database: Foreign keys or denormalized tables for immutable data?

Try adding this to your .emacs:

(defun nolinum ()
  (global-linum-mode 0)
)
(add-hook 'org-mode-hook 'nolinum)

This is assuming that you use linum and not something else to number lines. Anyway, you can add this hook to org-mode to disable anything that might make org slow only when you're using org-mode.

Disclaimer: I don't have linum installed so I can't test this, but it should work.

Write it by hand - it's the only way to get clean, simple, valid and semantic HTML and CSS.

If you're willing to forgo the semantics, you may want to look into a CSS framework, to take care of some of the layout busywork. I am not a fan of them, but I've heard others find them quite useful. Blueprint and 960.gs are the two I hear about most frequently.

那假設block=1024的話整個分區怎麼算?

分区大小和block数无关吧?不过RHEL5最大分区也好像是2TB。

SUID仅可用在“二进制文件(binary file)”,SUID因为是程序在执行过程中拥有文件拥有者的权限,因此,它仅可用于二进制文件,不能用在批处理文件(shell脚本)上。这是因为shell脚本只是将很多二进制执行文件调进来执行而已。所以SUID的权限部分,还是要看shell脚本调用进来的程序设置,而不是shell脚本本身。

Revised answer:

You can indeed insert your main UIViewController's view elsewhere in the UI as desired.

The trick is to do it early enough, and/or in the correct fashion. viewDidLoad isn't the correct place -- by the time that method is called, you usually want your main UIViewController implementation(s) to be in place.

There are two very good places to do this sort of UI setting up:

1) Via interface builder (nib files)

2) By implementing loadView in your UIViewController (do read the Apple docs -- very good info there).

It's one or the other, don't try do both at the same time for one UIViewController!

So in your example, you could use interface builder to edit a nib containing a tab bar controller. Drag in a plain UIViewController as a child of the tab controller, and then edit the 'Class' property of the UIViewController to MySpecialViewController (i.e. your subclass of UIViewController). And that's it, your nib now causes your view controller to be added to the UI inside a tab.

To taking approach 2), you'd want to set the viewControllers property of the UITabBarController in your loadView method of the UIViewController that contains the tab bar controller UI.

(My original answer below)

There isn't a consistently named way to access the root view controller(s) across Apple's provided view controllers (such as UINavigationController etc.). But the docs give you the info about how to access them; e.g. the UINavigationController has a property called viewControllers which you can access.

Ripping out existing view controllers willy-nilly and inserting them in different places in your UI is really not a very good idea. You could end up with all kinds of grief if you go down that round (e.g. device orientation changes). It's not the sort of approach Apple want you to take.

A better approach is to have several different instances of the view controller you want in different places. If they need access to the same data, they share the same data source. But they're individual, different instances.
