b) D: \ wwwroot \ test \ data \ db1.mdb file itself to the user ASPNET to the following privileges:

Next, open your database using Access file, create a new table, just a name, add an OLE object field in the table, and then add a record, before inserting text file created, if done correctly, it should be able to see to a new called "package" record. Can.
Simply put before the database file name with #, and then modify the database connection files (such as conn.asp) in the address database. The principle is to download it only recognizes blue bread bin the name of the part before the # sign for automatically removing the back, for example, you want to download: http://www.pcdigest.com/date/ blue bread bin # 123.mdb (assuming it exists). Whether or FLASHGET such as IE is down to http://www.test.com/date/index.htm (or index.asp, blue bread bin default.jsp IIS settings, such as your original home in the file name).
Also keep some space in the database file name also plays a similar role, due to the HTTP protocol blue bread bin to address resolution of particularity, spaces are encoded as "%" as http://www.test.com/date/123; 456.mdb, download time http://www.test.com/date / 123% 456.mdb. Our directory is no 123% 456.mdb this file, so the download is also valid for such changes, even if you are exposed to the address database, under normal circumstances people also can not download!
First, select "Tools -> Security -> encrypt / decrypt the database, select the database (eg: employer.mdb), and then determine, then there will be" after the database encryption Save As "window, saved as: employer1. mdb. then employer.mdb will be coded, and then saved as employer1.mdb .. It should be noted that the above action does not set a password for the database, but only to be coded to the database blue bread bin file, the purpose is to prevent others from using another tool to view the contents of a database file.
After this modification, even if the database was downloaded, others can not open (provided that your database connection page of the password is not leaking). But it is worth noting that due to the Access database encryption mechanism is relatively simple, even if the password is set, decryption is also very easy. The database system password entered by the user with a fixed key "exclusive or" to form an encrypted string, and stores it in *. Mdb files from within the region address "& H42" began. So a good programmer can easily create a small line of dozens of programs you can easily get the password to any Access database. Therefore, as long as the database is downloaded, the information security is still unknown.
This method is achieved by modifying the IIS configuration, suitable for control of IIS friends, but not for purchase virtual host user (unless the administrator has set up). This approach I think is the best, just modify an entire site database can be prevented from being downloaded, and even without modifying the source code can also prevent exposure blue bread bin to the target address to be downloaded.
We already know, ASP.NET using ADO.NET to access the database, Access database can be accessed via OleDb connection, one of our very popular low-end database. This article discusses a number of error messages you might see in ASP.NET, which saw AccessXP Access2000 and database blue bread bin files created when an error occurs less access to the same error. We want to help. Another important point is that I hope that through this article, so that everyone on the NTFS permissions in ASP.NET Access database file settings have a new understanding.
