In order to pull live listing information, the servers pulling this data have to go through an agent’s connection with their local MLS. (Don’t ask me to explain why, and definitely don’t ask Robbie, but anyone reading RCG for a while knows that the MLS’ have rules!) The result is that it takes 5 to 15 minutes for Top Producer’s servers to pull the data off of the MLS servers (yes, a server call to the local MLS is necessary each and every time a request for a snapshot is made). Consequently, the only way to get your snapshop is from a link sent via email about 10 minutes after you complete the form.

Doing things in VB.net instead of C# may make things a little easier for you given your background. Also, there's no law saying you can't implement your site in PHP if your more comfortable with that toolset. If you're just getting started with ASP.net, I'd recommend playing with the ASP.net 1.x tutorials on <a href="http://www.dotnetjunkies.com/quickstart/aspplus/doc/quickstart.aspx" rel="nofollow">Dot Net Junkies</a> and the ASP.net 2.0 tutorials on <a href="http://www.asp.net/quickstart/aspnet/" rel="nofollow">asp.net</a>.

I understand that you cannot help me much further than you already have but it was worth a shot. Allen: I already have access to the feed and can make queries to it without a problem. I will not be storing any of the data in my own db, only making query requests to provided server. As Robbie said above, I feel the same way about putting the information into a useful form. I am new to ASP.NET but have a background in PHP and Visual Basic. I'm using SqlDataSource & GridView - I guess I'll be squeezing out everything my brain has! Thanks guys, Ron Robbie,

If your crazy enough to develop an NWMLS search tool from scratch, I'd recommend the following... Join the NWMLS dev forum at <a href="http://groups.yahoo.com/group/NWMLS-EverNet/" rel="nofollow">http://groups.yahoo.com/group/NWMLS-EverNet</a>. I'd recommend you take advantage of the new SqlDataSource & GridView controls in ASP.net 2.0. I'd recommend you learn about dynamic image pages in ASP.net.

So, if you want to convert Fahrenheit to Celsius, do it in SQL since it's much faster, if want to do radius searches, it's a virtual tie and if you want to do something more CPU intensive, use a CLR or native code based proc. I didn't know where that line of diminishing returns was.

With MS SQL 2005, you can have procs written in .net or native code. (I believe <a href="http://www.oracle.com" rel="nofollow">Crazy Larry's database</a> has similar capabilities, but I'm talking about MS SQL, cause that's what I know best). Also x86 CPUs have had floating point processors built in for the past 10+ years. So floating point math on a PC can be pretty quick these days, if you let the hardware do it. Most of the intermediate calculation methods I've seen take a lat & long and cache x, y, & z coordinates. So you've now increased the amount storage you need for location information, which will slow things down a bit. However, historically speaking SQL look-up is "fast" and calculation is "slow", so this approach makes sense. But with .net or native code procs, SQL calculation is now "fast", it now could be faster to calculate it on the fly, than it is to store & retrieve it. Then again, it might not be. I'm still using SQL 2000, so the discussion is kind of moot at the moment now anyway (I should be caching the intermediate calculations). But when I move to SQL 2005, I'll definitely be comparing both approaches to see if the old rules are still the best ones. I wonder if that’s still the case today though?
