RUNAS 使用方法:
 
RUNAS [ [/noprofile | /profile] [/env] [/netonly] ]
        /user: program
RUNAS [ [/noprofile | /profile] [/env] [/netonly] ]
        /smartcard [/user:] program
   /noprofile        指定使用者的設定檔不該載入。
                     這會導致應用程式載入速度更快，
                     但可能引起一些應用程式運作失常。
   /profile          指定應該載入使用者的設定檔。
                     這是預設值。
   /env              使用目前的環境，不用使用者設定的環境。
   /netonly          如果指定的憑證是供遠端存取時才使用。
   /savecred         使用之前由使用者儲存的認證。
                     此選項在 Windows XP Home Edition 上無法使用
                     而且會被略過。
   /smartcard        當智慧卡提供了認證時使用。
   /user              格式如下 USER@DOMAIN 或 DOMAIN\USER
   program         EXE 的命令列。範例如下
範例:
> runas /noprofile /user:mymachine\administrator cmd
> runas /profile /env /user:mydomain\admin "mmc %windir%\system32\dsa.msc"
> runas /env /user:user@domain.microsoft.com "notepad \"my file.txt\""
注意:  只有在提示時，才輸入使用者密碼。
注意:  USER@DOMAIN 與 /netonly 不相容。
注意:  /profile 與 /netonly 不相容。

ボタンをクリックすると、data()のオブジェクトがハンドルを値を持っているため、postするときにハンドルは再び執行することになる。つまり、クリック事件は繰り返しする。この現象を避けるには、ハンドル/イベントを削除しなければならない。

Statement.executeBatch() always returns an array of value -2

Java Memo Oracle

The elements in the array returned by the method executeBatch may be one of the following:

A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
A value of -2 -- indicates that the command was processed successfully but that the number of rows affected is unknown
If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
A value of -3 -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails

Word break tag : (HTML5)

html

The HTML tag is used defines a potential line break point if needed. This stands for Word BReak.

This is used with the tag, advises the extended browser when it may insert a line break in an otherwise nonbreakable sequence of text. Unlike the tag, which always causes a line break, even within a - tagged segment, the tag works only when placed inside a - tagged content segment and causes a line break only if the current line has already extended beyond the browser's display window margins.

test:

Words without breaks

no object DCH for MIME type multipart/mixed

Java

Caused by: javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/related; 
 boundary="----=_Part_0_9042915.1299319807397"

 ... 4 more

There is something wrong with MailCap, javamail can not find a handler for such multipart/mixed part.
And the solution is add mime programmingly:

MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);
