The RETS system allows us to update our local real estate databases throughout the day, and each update takes only minutes to do. What’s more, it has required no human intervention since it started running over 6 months ago. It has been a set it and forget it operation, which I like very much.

I was able to script a RETS “replicator” that keeps our local databases in sync with the main MLS RETS databases, so that MLS listings appear in our local database only very shortly after entry into the main RETS systems. The replicator is written in vbscript as an .asp class, and right now is scheduled on windows task scheduler to run every couple hours thoughout the day. It utilizes the open-source ezRETS ODBC Driver available from California Association of REALTORS (C.A.R.) at http://www.crt.realtors.org/projects/rets/ezrets/

After experimenting with various methods to connect to RETS and script a solution, it was clear that ezRETS was the winner. I plan to make the RETS replicator .asp class available here soon. It has been tested and running smoothly on a Windows 2000 server for the better part of the last year.

Requirements to run the RETS replicator .asp class application are the open-source ezRETS ODBC Driver, and a realtor login to the RETS system.

Our local RETS system uses a a Rapattoni Rets MLS Server, and the script is set up with the field names for our local MLS server. Modifications to the field names will probably be needed to enable the script to talk to other servers.

I did learn that even though the RETS system is striving to institute standards in real estate data transfer, the RETS MLS systems still differ somewhat in their database setups. Field names can vary on different types of MLS servers and even within the same brands of RETS servers from different RETS MLS offices. RETS MLS systems are not databases in the traditional sense like SQL Server or MySQL, but are instead IDX systems with pointers to the records. This can be somewhat tricky for developers to deal with when starting to develop a RETS solution. This is where ezRets really helps, it converts traditional SQL statements into IDX commands that the RETS MLS system understands.

The email will then be viewable in any modern email client that supports secure certificates. But it will only be viewable if the email recipient has your certificate installed.

You may create your own private email cetificates using tools like the openssl toolkit. Email certificates are also free at most of the major ssl providers.

Also see the PHP version of encrypted emails on this site that sends encrypted emails.

In VB you must also add a reference to System.Security in your project in Visual Studio Express.

Below are the VB.NET and C# versions of the code for encrypted emails using ssl certificates:

Shared Sub Main(ByVal args() As String)

  SendEncryptedEmail("test.pfx", "test.cer", """Somebody"" ", """Somebody"" ", "Test VB Encrypted HTML EMail", "This email is encrypted and signed.", "localhost", 25, False)

End Sub

    Shared Sub SendEncryptedEmail(ByVal SigningCertPath As String, ByVal EncryptingCertPath As String, ByVal [To] As String, ByVal From As String, ByVal Subject As String, ByVal Body As String, ByVal SmtpServer As String, ByVal SmtpPort As Integer, ByVal HTML As Boolean)

Visual Basic
You’ll shoot yourself in the foot, but you’ll have so much fun doing it that you won’t care.

Prolog
You tell your program you want to be shot in the foot. The program
figures out how to do it, but the syntax doesn’t allow it to explain.

Ada
After correctly packaging your foot, you attempt to concurrently load
the gun, pull the trigger, scream and shoot yourself in the foot. When
you try, however, you discover that your foot is of the wrong type.

Assembly
You try to shoot yourself in the foot only to discover you must first
reinvent the gun, the bullet, and your foot. After that’s done, you
pull the trigger, the gun beeps several times, then crashes.

The fix to this problem is to enable a firewall on the user’s PC.

This is the fix that worked for me. During my search for a fix I noticed that this is a widespread problem with Firefox.

It seems that this message occurs in Firefox when one disables the Windows firewall service. I had inadvertently disabled the service, and that was when the messages started occurring. After I enabled the Windows firewall service the “incorrect Message Authentication Code” messages stopped.

According to the people at the MozillaZine forums, any firewall will do, it is not necessary to use only the Windows firewall. But a software firewall needs to be enabled.

Some people on the forum feel that this points to spyware or viruses on the user’s PC. I have scanned my PC and found no traces of spyware or viruses, so this may be a problem with Firefox.

They asked me if I would answer a few questions about “Household Services”. In return for my time, they promised that I would receive a ten dollar gift card from Target.

“Yeah, right, another scam”, I thought.

But the offer was enticing and I went ahead and answered about ten minutes worth of yes/no questions. At the end of the question and answer session, they took my name and address and promised to send me the gift card. I didn’t really believe them, but I took my chances and gave them the information.

About two weeks later my gift card arrived in the mail! I went to Target and splurged on some clearance items, parlaying my ten dollar bonanza into a sizable value based on original retail. All is well.

Moral of the story – be very careful, but sometimes telemarketers can be trusted!
