I was just wondering, when you create dataContext methods, should you put business logic there to try and minimize pushing data through 2-3 layers of code? or should the business logic still go in another class somewhere making it access the dataContext methods?

I need to create a few XAML FlowDocuments. Although I have done some very simple ones by hand-editing of XML, I can't help but think there must be a graphical-editor way of doing it. I believe Visual Studio 2005, which I am using for my project, cannot do it. But various Web sites suggest that Visual Studio 2008 does have a graphical editor...

When I...

Hi Willy, Thank you very much for your work. C++ code doesnot make any serialization. So at runtime C# code gives an serialization error at "msg_file_s sa = (msg_file_s) bf.Deserialize(ms);" I thought that it is very hard to memory map structure array. I need both read and write memory mapped file at both side of C# and C++.

What's the best way to debug code that is being run during garbage collection? We are getting AccessViolationExceptions that seem to be happening during garbage collection. But when it hits the debugger, it is at whatever line of code the main thread was at when the garbage collector decided to run. In other words, the debugger is in...

Hi all, Using Expresso, I've come up with this to parse chat lines: (?<chatdate>\d{4}\.\d{2}\.\d{2})\s(?<chattime>\d{2}:\d{2}:\d{2})\s]\s(? <speaker>\b\w*\b(\s\b\w*\b)*)\s>(?<message>.*) As far as I can see, it suffers only from the defect of including the CR at the end of each chat line in the capture. I've tried for the message...

Extension methods are made for use with instances. I'd like to "misuse" them as static methods, too. Let me tell you my ambition: I use an extension method to serialize objects somehow like this: MyObject obj = new MyObject(); obj.ToXmlFile("some directory\\some file.xml"); The method "ToXmlFile" is defined elsewhere far apart from...
