Do you still love working with Delphi 7? I do. Delphi 7 is quite old and there are many features on the new Windows 7 that it’s not able to do. Today i faced a problem with UAC, my application needs to run under administrator account, when UAC is enabled, i can’t detect if the user is running with admin account or not. With the new application, the application can force the user to run in administrator mode when UAC is enable easily. Luckily, there is a solution on now. 1.

Long time ago, when i design the database, i never think of the character set for my database. But recently, i have to work on some non-english language like Chinese and Korean. I found that my database does not store the info correctly. So here is my suggestion: No matter if you decide to support multiple language or not, when you design your database, you should use UTF-8 as the character set. If you are using mysql and your database is not not with UTF8 – you should use this query to convert it to UTF8. ALTER TABLE table_name CONVERT TO CHARACTER SET utf8 COLLATERead More →

I have a Chinese text file that’s not encoded in UTF8 , it’s encoded with gb2312 . I have been struggling to insert it into mysql. When i copy the text file & import it to mysql via phpmyadmin, it display chinese character very well, but if i use php to insert it, it display some weird characters. It turned out that i need to re-encode gb2312 to ut8 in php before inserting to database. The reason when it’s working fine via phpmyadmin, it’s because when we copy & paste, the browser already re-encode from gb2312 to utf8. here is the function i use: $text=Read More →
