I looked at the ruby documentation for StringIO, and it looks like what you want is [strio.string][1], not strio.to_s
Thus, change your code to:
s = StringIO.new
s << 'foo'
s << 'bar'
s.string

The one reason this might be the case is that the XML file is no longer being created/updated. Make sure the XML Documentation file is set in the project property pages. Has your XML file been put under source control and if so is it checked out on a build. If not then it won't update. |

I think your plan is pretty good, really. How will you account for branches where a programmer is wandering off on their own just trying something? Maybe like /development/jfm3-messing-around ? |

I think flexibility and avoiding ambiguity is your answer.

Best thing to do is don't assume anything if you can. When the operator types in your application name for execution and does not have any parameters either hit them with a USAGE block or in the alternative open a Windows Form and allow them to enter everything you need.

If you absolutely cannot increase the timeout, your only option is to reduce the time of the query to execute within the default 30 second timeout.

This sounds like a question based on a background in java?

This is an example from Excel documentation:

So the Characters property of the cell you want to manipulate is the answer to your question. It's used as Characters(_start_, _length_). |

An index basically sorts your data on the given columns and then stores that order, so when you want to find an item, the database can optimize by using binary search (or some other optimized way of searching), rather than looking at each individual row.

An index can be explained as a sorted list of the items in a register. It is very quick to lookup the position of the item in the register, by looking for it's key in the index. Next the the key in the index is a pointer to the position in the register where the rest of the record can be found.

Yes, exceptions are expensive so there is a cost involved in catching and rethrowing or throwing a more useful exception.
