At work we have a native C code responsible for reading and writing to a proprietary flat file database. I have a wrapper written in C# that encapsulates the P/Invoke calls into an OO model.

I'm developing a class library that will be used in a number of different web applications, and possibly even made available as an open source project. There are several points where I would like to use IoC, but I don't want consumers of the class library to have to use one particular implementation. What is the best way to design this...
As a part of our build process we want to execute SQL Scripts consisting of DDL and DML statements against a fresh database instance. ADO.NET Connection/Command can't handle this without parsing and splitting the scripts. The sqlplus command line utility can execute scripts only interactively, and isn't suited for batch usage.

Where I work we're finally coming around to the idea of using strongly typed datasets to encapsulate some of our queries to sqlserver. One of the idea's I've been touting is the strength of the strongly typed column's, mainly for not needing to cast any data. Am I wrong in thinking that strongly-typed-datasets would improve performance ...

It would be desirable for the page to be launched in the user's existing browser window, if one is open. The current means of launching the browser always creates a new window: Process p = new Process(); p.Sta...
I'm working on a regression-testing tool that will validate a very large number of Excel spreadsheets. At the moment I control them via COM from a Python script using the latest version of the pywin32 product. Unfortunately COM seems to have a number of annoying drawbacks: For example, the slightest upset seems to be able to break the c...

Our Exchange server generates about 100MB of message tracking logs per day. Deep inside these logs are email send failure reports that we want to extract. We have a transactional site that sends confirmation emails to the customer at the end of the transaction. We require the user to enter their email address twice, in two textboxes. If...
