Simple question:
What is the pattern for the word character \w in c#, .net?
My first thought was that it matches [A-Za-z0-9_] and the documentation tells me:
Character class Description Pattern Matches
\w Matches any \w "I", "D", "A", "1", "3"
word character. in "ID A1.3"
which is not very helpful.
And \w seems to match äöü, too. What else? Is there a better (exact) definition available?
We are developing a very complex eCommerce portal using asp.net c# and the client asked us to make the documentation very similar (look & feel) with ebay api documentation http://developer.ebay.com/DevZone/shopping/docs/CallRef/GetSingleItem.html
Do you have any idea what kind of tool they are using and if not do you know anything that can be configured to produce a similar result ?
Thank you in advance !

Hello
I have a .NET CF project. In the project directory I put a simple xml file (users.xml) which has to be read by the device. When I debug the application on device emulator and try to load the file from code, the Exception is thrown (FileNotFoundException "Could not find file '\users.xml'.").
Is there a mechanism to automatically deploy also configuration files to a device emulator?
We are running an ASP.NET app on a web server with 4GB+ of memory in IIS 6. After reading many articles, it states that we need to set the "maximum memory used" for the Application Pool to 800mb to eliminate the "out of memory exceptions" that are happening for us. However, what should the "maximum virtual memory" in the Application Pool be set to? I can't find information as to what that should be set to.
I migrated an asp.net app to 4.0. Now I am getting an error "The type or namespace name 'IQueryable' could not be found". The reference to System.Linq is invalid and I can't find it in the reference list. Where did System.Linq go?

Is it possible to host 2 asp.net projects off one ip address? I don't have a domain name just an ip number. I'm running IIS7.
The first project runs and displays fine over the web by simply typing in the ip address into the browser but I'm having trouble accessing the second.
Currently both projects have virtual directories in IIS7.
Help is greatly appreciated.

For Australian companies and start-ups, what’s the best ASP.NET web hosting in the country? Should a company consider hosting its website overseas even if the potential market is in here?

I want to detect if a window form is open and if it is then I would like to bring it in front rather than opening it again.

I need to compare tables with the same names in different databases ( Sql Server 2008 ). How using C# code and ADO.Net to identify additions, deletions, updates. Is DataReader going to work in this scenario without stored procedures ? DataReader seems to be suitable for single database connection, or am I missing something ?
