C#/.NET: FInd out whether a server exists, Query DNS for SVC records.

- by TomTom

Writing a cleint/Server tool I am tasked trying to find a server to connect to. I would love to make things as easy as possible for the user. As such, my idea is to: CHeck whether specific servers (coded by name) exist (like "mail.xxx" for a mail server, for example - my exampüle is not a mail server;) Query otherwise for DNS SVC records, allowing the admin to configure a server location for a specific serivce (that the client connects to). The result is that the user may have to enter only a domain name, possibly even not even that (using the registered standard domain of the computer in a LAN environment). Anyone ideas how: To find out whether a server exists and answers (i.e. is online) in the fastest way? TCP can take a long time if the server is not there. A UDP style ping sounds like a good idea to me. PING itself may be unavailable. Anyonw knows how to ask from withint .NET best for a SVC record in a specific (the default) domain?

WCF: How to find out when a session is ending?

- by TomTom

I have a WCF application that is using sessions. Is there any central event to get thrown when a session ends? How can I find out when a session is ending WITHOUT (!) calling a method (network disconnect, client crashing - so no "logout" method call)? The server is hosted as: [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Reentrant, UseSynchronizationContext = false, IncludeExceptionDetailInFaults = true )] Basically because it is using a callback interface. Now, I basically need to decoubple the instance created from the backend store when the session terminates ;) Any ideas?

SharePoint (2010): Field for (multi) currency...?

- by TomTom

Hello, old problem now getting new. Anyone has a good idea for storing currency values in a sharepoint list? Problem is - there is a currency field, but it is not multi-currency enabled. I could obviously store the value in two fields (currency lookup from a list, value in second field), but I take it as wondering whether there is a more viable approach that.

Best client for SVN / WIndows for READ ONLY ;)?

- by TomTom

Not interested in any source control OR shell integration. This is basically to make regular gets on certain third party archives. I would really prefer not to deal with SVN in any way in my shell or visual studio. Native / C# preferred (as i have those runtimes already installed). Anyone a recommendation under those circumstances?

.NET Regex - need matching string for parsing...

- by TomTom

Hello, I am a regex idiot and never found a good tutorial (links welcome, as well as a pointer to an interactive VS2010 integrated editor). I need to parse strings in the following form: [a/b]:c/d a, b: double with "." as possible separator. CAN be empty c: double with "." as separator d: integer, positive I.e. valid strings are: [/]:0.25/2 [-0.5/0.5]:0.05/2 [/0.1]:0.05/2 ;) Anyone can help? Thanks

Mostly interested in how to hide the SharePoint "particulars". For example whether to use the base site as "Wiki" and in this case - how to hide the "SitePages" folder and other SharePoint specifics. And links to any pages / Documents helping there ;)

Resources for creating a turn-by-turn navigation system

- by benwad

I'm trying to create a kind of turn-by-turn satellite navigation system using the iOS SDK. I get the directions from the server and draw them on the map, then I keep getting location updates from the iPhone's GPS chip. Currently I start by finding the nearest turning point then, each time the user comes within a certain distance of the next turning point, a verbal cue is given and the turning point index is incremented. This is a delicate system and I'd like to make it more robust so I can tell when the user is going the wrong direction etc. Basically I'm looking for some literature about turn-by-turn navigation, in terms of tracking the user's progress and whether they're going the right direction. I'd have thought there's a lot of research out there but I can't seem to find anything apart from simple tutorials on how to use a given SDK or directions API. Can anyone direct me to a good run-through of the various techniques used in software such as TomTom or Google Maps Navigation?
