MultiValue and QuickBooks, Part 2: Exporting to 14 MultiValue Many MultiValue accounting packages lack the GUI interface modern users demand or other features that are considered to be mandatory by anyone who has used a modern accounting application. One option is to replace it with an off-the-shelf commodity accounting package and share data between it and the MultiValue Departments system running the core business functions.

UCS characters U+0000 to U+007F (ASCII) are encoded simply as bytes 0x00 to 0x7F (ASCII compatibility). This means that files and strings which contain only 7-bit ASCII characters have the same encoding under both ASCII and UTF-8. All UCS characters above U+007F are encoded as a sequence of several bytes, each of which has the most significant bit set. Therefore, no ASCII byte (0x00-0x7F) can appear as part of any other character and all possible 231 UCS codes can be encoded. The first byte of a multi byte sequence is always in the range 0xC0 to 0xFD and it indicates how many bytes follow for this character. The bytes 0xFE and 0xFF are never used in the UTF-8 encoding, which is good news for field marks. The following byte sequences are used to represent a character. The sequence to be used depends on the Unicode number of the character: U-00000000 – U-0000007F: 0xxxxxxx U-00000080 – U-000007FF: 110xxxxx 10xxxxxx U-00000800 – U-00007FFF: 1110xxxx 10xxxxxx 10xxxxxx (etc) Fig. 1 INTERNATIONAL SPECTRUM March/April 2011 u 7 The PHANTOM running in the background Character Encodings UTF-16 is the regularly spaced double ® byte encoding we just met.

If such is the case in your shop, your e-mail messages will
12 u intl-spectrum.com end up in the Badmail folder with cryp- tic router error-message files. If a smart host is available on your network, you can use it to relay all SMTP messages to the Internet. In most cases, a smart host is simply another SMTP server with permission to relay outgoing e-mail messages from other internal SMTP servers directly to the Internet. Thus, a smart host should be able to connect simultaneously to both the internal network and the In- ternet to work as the e-mail gateway. If this setup exists in your company, you can simply add the IP address of the smart host on your network and IIS will send its e-mail messages to that SMTP server for relay to the Internet. To set up a relay to a smart host on an IIS machine, follow these steps: Open ISM, right-click the SMTP server, then select Properties. Click the Delivery tab, and then click Advanced to open the Advanced Deliv- ery dialog box, which figure 1 shows. Fig. 1 In the Smart host field, type either the smart host’s Fully Qualified Do- main Name (FQDN) or its IP address surrounded by square brackets (e.g., [10.1.4.25]). The brackets help speed up the DNS lookup process by specifi- cally telling the SMTP server that the numbers are an IP address. Click OK twice to complete the changes. In the Advanced Delivery dialog box, notice the Masquerade domain field. The masquerade domain makes an e- mail message look as though it came from a point other than its true origin. You can easily fake return addresses on e-mail messages. For example, if I enter “MyDomain.com” in the Masquerade domain field, mail messages would ap- pear to come from addresses such as [email protected].

One solution is to use the “https” protocol, which encrypts all the data traveling between the browser and the web server, but this introduces a performance penalty, and if the only “secure” data is the password, it may be overkill. An alternative (in those instances that don’t require full “https” security) is to encrypt the password in the browser before sending it across to the web server. In this way, the “plain text” password is never transmitted, and thus cannot be intercepted; the encrypted value is stored in the database, and it is Fig. 2 Behind the scenes: Encryption “event” on button INTERNATIONAL SPECTRUM March/April 2011 u 21 First Steps To Securing Your Information In The Internet Age Continued from page 21 ues on different systems.
