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?

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?

Hi,
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 know I need a form collection for this but I want to know if there is a built in form collection that holds all the forms in VB.NET or I need to implement my own.
Thank you.

I am writing a C# application and I would like to make calls to different matlab functions simultaneously(from different threads). Each Matlab function is located in its own compiled .net library. It seems that I am only able to call one Matlab function at a time however.
ie, if matlab_func1() gets called from thread1 then matlab_func2() gets called from thread2, matlab_func2() must wait for matlab_func1() to finish executing.
Is there a way to call different matlab functions simultaneously? Thanks.

Hello,

I am looking for the easiest way to generate a Word document on our server.
Limitations :
Server side
I don't want to install word on the server
Data source is XML
I tried to generate a DOCX with XSLT which is fast and easy but the only way I could find to validate the generated document is to open it with Word and the only error I get when the document is not valid is "Error while opening document". Not very useful.
Any ideas?
Thanks,
Alex

I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well.
Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.
In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value."
I sometimes see these inter-mixed in the same function. Personally, I prefer the return.
My question is, what is the internal difference, if any, between the two?
