基于事件驅(qū)動的串口通訊控件
消息幀數(shù)據(jù)格式:
1 0 A B X X
其中 10 為消息標(biāo)識,
AB表示文本長度,L=A*100+B
XX為配位字符,任意
控制幀數(shù)據(jù)格式
0 1 A B M N
其中 01為控制標(biāo)識,
AB為請求標(biāo)識
MN為附加標(biāo)識
11表示請求對方接收文件,M表示描述字串中文件名子串的長度
N表示描述字串中文件大小子串的長度
10通知對方放棄傳輸
00通知文件傳輸完畢
01請求對方發(fā)送數(shù)據(jù), MN為10請求發(fā)送下一個
MN為00請求重發(fā)

其中 00 為數(shù)據(jù)標(biāo)識,
AB表示數(shù)據(jù)長度,L=A*100+B
MN為校驗,M*100+N=A+B
About:
hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases.
Release focus: Major feature enhancements
Changes:
This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download.

Problem B:Longest Ordered Subsequence
A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. For example, sequence (1, 7, 3, 5, 9, 4, 8) has ordered subsequences, e. g., (1, 7), (3, 4, 8) and many others. All longest ordered subsequences are of length 4, e. g., (1, 3, 5, 8).
