OCR (Optical Character Recognition) is an interesting issue. I’ve found that some (built-in) libraries in Windows 7/Server 2008. If you want to develop OCR program without extra fee, you should try it. Window 7 OCR API : In the final answer, you can use thocr.psp.dll ,xocr3.psp.dll, and ximage3b.dll. Using IFilter in C# : If you want to use […]

[PHP] MySQL Backup by GMail
[Chinese] 先前已經介紹過有一個好用的MySQL資料庫備份工具(使用PHP):MySQLDump。但是預設的寄信函式,是透過SMTP伺服器寄信,這對於沒有SMTP伺服器的使用者而言,可就傷腦筋了。原先我有找到一篇教學,使用GMail的SMTP伺服器做備份,可惜連結已經失效了。筆者只好自行撰寫,由於程式碼使用GPL授權,基於分享的精神下,便公開給各位。 程式碼下載處:請按我。 [English]I’ve introduced an useful backup tool for backuping MySQL databases (using PHP): MySQLDump. However,the default send mail function uses the SMTP server to send mails, and it may cause some problems for the users without SMTP servers. Initially, I’ve found one tutorial for teaching that how […]
[DB] SQL Server 2005 can not be installed in AMD X3 (X6) platforms.
[Chinese/中文] 起初,MS SQL Server 2005的開發人員並未考慮到奇數CPU核心的出現,而傻傻的認為所有的CPU核心都一定是偶數個且為2的冪次。但是這樣的天真想法,在AMD X3/X6 CPU出現後,就造成相容性以及無法成功安裝的問題,因為這些CPU都是使用奇數核心。 SQL Server 2005在Service Pack 2後,可以支援奇數核心。但是,就先前提及的,都無法安裝成功了,哪來的更新可言。 最直接的解決辦法是修改BIOS。使用者可以直接到BIOS選單,選擇”CPU configuration”->”Clock Calibrating”,然後關閉一些核心,讓核心數量維持在2的冪次(也就是說,如果是使用AMD X3 CPU的話,只要關掉第3個核心。若是使用AMD X6,則關閉第5與第6個核心)。在這子調整過後,筆者相信您應該可以享受SQL Server 2005的安裝過程了。 [English] Initially, the developers of MS SQL Server 2005 didn’t consider the appearance of odd CPU cores and they just thought that all the numbers of CPU […]
