平時用 MS Access 就用得多, 其中有一個叫 format 既 function 可以將資料用規定特定既格式輸出. 但係有日係 Excel 就唔識用, 仲搞咗好耐. 最後當然俾我搞掂, 就係用 Text() , 例如 =Text(7,”00″) 輸出結果為 07

下次有機會再同各位研究一下.

[轉載] Hackers Exploit Access Database Flaw

A hole in Microsoft’s Access database permits hackers to install software on vulnerable systems, the US-CERT team warns.
Robert McMillan, IDG News Service

Online criminals are exploiting a flaw in the Microsoft Office Access database to install unauthorized software on computers, the United States Computer Emergency Readiness Team (US-CERT) has warned.

In its brief warning, US-CERT offered few details on the attack, saying simply that the organization is “aware of active exploitation” of the problem by criminals who have sent specially crafted Microsoft Access Database (.mdb) files to victims.

These files are “designed for the sole purpose of executing commands,” so they should not be accepted from untrusted sources, Microsoft said in a note on its Web site.

Run by the U.S. Department of Defense, US-CERT is charged with coordinating the nation’s response to cyberattacks.

Companies typically block the use of .mdb files, but criminals could be using this attack in a targeted strike against an organization that is known to use this particular file-type, said Ben Greenbaum, senior manager for Symantec security response. Symantec itself has seen no evidence of the .mdb exploitation that prompted the US-CERT alert.

The files are not something that the average user would come across on a daily basis, he added. “.Mdb files are blocked by default in most installations of Internet Explorer and Outlook Express,” he said. “I am a bit surprised to see active exploitation happening over this vector.”

While US-CERT did not say which flaw was being exploited, Greenbaum said the vulnerability could be a recently discovered buffer overflow bug in the Microsoft Jet DataBase engine used to parse Access files.

Age calculation in MS Access

今日係公司諗緊用一個最有效既方法用出生日期去計算年紀. 以下為得出之答案:

= Fix(DateDiff(“y”, [Input Date], Now()) / 365.25)

解說:

Fix 是只取除數後既整數, 忽略餘數;

因為一年為 365 日, 而每 4 年會多 1 日, 所以平均會多 0.25 日
