Create a new Running Total Field called, for example "RTotal". In "Field to summarize" select "Value", in "Type of summary" select "sum", under "Evaluate" select "For each record". You can then drag this field into your report to use as the "Total" at the bottom of each page.

There's an easier way. Just create shortcuts (called linked files in Visual Studio-ese) in your wrapper.dll project that point to the source files in api.dll. That will compile your source directly into wrapper.dll. |
I would disagree with the premise that it's better to return an interface. You want to maximize the usefulness of your code. That means accepting more loosely defined values as arguments (ie: _void MyFunc(IEnumerable<T> myParameter)_ ), and returning more strongly defined values (ie: _List<T> MyFunc()_ )

One possibility I can think of is to store the count in a member variable of the class. This of course assumes that the public <code>doIt</code> method is only called by a single thread.

I agree with Hershi's suggestion to use a template as the "base class". From what you're describing, it sounds more like a use for templates rather then subclassing.
You could create a template as follows ( have not tried to compile this ):

How to benchmark a SQL Sever Query? |

I'd like to know the standard way to benchmark a SQL Sever Query, preferibly I'd like to know about the tools that come with SQL Server rather than 3rd Party tools. |
In SQL Server 2005, placement of nullable variable length columns has a space impact - placing nullable variable size columns at the end of the definition can result in less space consumption.
SQL Server 2008 adds the "SPARSE" column feature which negates this difference.

I only have experience with Subversion but I can tell you that the merge screen in TortoiseSVN is horribly complicated.

How can I get the definition (body) of a trigger in SQL Server? |

Unable to find a SQL diff tool that meets my needs, I am writing my own. Between the INFORMATION_SCHEMA and sys tables, I have a mostly-complete working version. But one thing I can't find in the metadata is the <em>definition</em> of a trigger, you know, the actual SQL code. Am I overlooking something?
Thanks. |

You could use [Narrative JavaScript][1], a compiler that will transforms your code into a state machine, effectively allowing you to emulate threading.
