点阵字体产生工具以及相关显示函数。
在开发嵌入式系统时,需要显示不同大小或类型字体的汉字。显然,对于嵌入式系统,不太可能使用矢量字体,而点阵字体,不同大小的字体不能简单的缩放。 另外,对一个小系统,也不需要完整的字体,往往只要几十个,甚至几个就够了。
一般,我们采用的方法是,自己准备点阵字体的数据,在显示汉字时,把这些数据写入显存就行了。 这时又存在另外一个问题,由于是不完整的字库,不能简单的用汉字的内码去找到对应的字体数据,如果逐个比较,又费时间。比较好的方法就是把字体数据排序,用二分法查找,这样可以大大提高查找效率。
这里为以上问题提供了一个完整的解决方案:
产生字体数据:指定字体类型、大小,自动产生字体数据。
字体数据排序:可以按Unicode,也可以按Ansi排序。
集成显示函数:提供相关显示函数。为了节省空间,我们把文字分成thin和wide两种,前者用于显示传统的ASCII字符集,后者用于显示汉字等多(双)字节字符

DataAdapter
使用DataAdapter对数据库进行操作
将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作.
程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database
The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object.

Energy efficiency is the most important design goal
for wireless sensor networks (WSNs). In this paper, we propose
an energy-efficient cooperative MIMO scheme, which
combines energy-efficient LEACH (EE-LEACH) protocol and
cooperative MIMO. We name it as EE-LEACH-MIMO
scheme. EE-LEACH is an improved LEACH algorithm, in
which the network is partitioned to sectors with equal angle for
avoiding the distribution non-uniformity of cluster heads. In
EE-LEACH-MIMO scheme, the location and the residual
energy of each node are considered when the cluster heads for
clustering and cooperative nodes for MIMO system are chosen.
For comparisons, LEACH, EE-LEACH, the simple
cooperative scheme with LEACH and MIMO (LEACHMIMO),
and EE-LEACH-MIMO scheme are simulated. The
result shows that EE-LEACH-MIMO scheme can well balance
the network load, save energy and prolong the network
lifetime
