Yes, that step 4 from my previous post is a doozy.
No matter what, you're probably going to have to do some of this by hand, but you may be able to automate the bulk of it. For the example locations you gave, a query like the following would set the appropriate company_id value:

Basically, this is a text categorization problem/document classification problem. If you have access to a number of already tagged documents, you could analyze which (content) words trigger which tags, and then use this information for tagging new documents.

In general, I would recommend sending an acknowledgment from the client anyway. That way you can be 100% sure the data was received, and received correctly. |
This is one of those questions best answered by: Why are you trying to do this in the first place? What is the concurrency against those databases? Are you generating databases when you could have normalized tables to do the same functionality?

One way to do this is to have a type field as the first byte of the structure. Your receiving function looks at this byte and then casts the pointer to the correct type based on what it discovers. Another approach is to pass the type information as a separate parameter to each function that needs it. |

I think the very short answer to your question is to use WITH clauses to generate your own.

It might be worth looking into [Jersey][1]. Jersey makes it easy to expose restful web services as xml and/or JSON.

Further to the previous answers, the first thing I always do when thinking of issues like this is to create a small test application. Inside this app, perform some timing test for both scenarios and see for yourself which is quicker.
IMHO, appending 500+ string entries should definitely use StringBuilder. |
What I do in these cases is open a blank line between the paragraph lines and the argument lines, then use M-q to wrap the paragraph lines, then kill the blank line between them. Not ideal, but it works and is easy enough to record in a macro if you need to repeat it. |

Well - I don't know if your initial code block would work, but I'm guessing you have to mark your new e2 as insert on submit. Thus:

Option 1 is my favourite because it is the simplest. I get to launch the app in the normal way without worry about getting WinDbg to set the right working directory, pass any command line arguments, etc.

Smart Inspect from [Gurock Software][1] has come in handy many times for me. It is very easy to put into a .NET application and gives you extremely powerful control when analyzing log files.

grep probably isn't the tool you want for this. It will print a line for every matching line in every file.

I would use one of the out-of-the-box XML serialization classes to do your internal XML generation, and then use XSLT to transform to the external XML.
