• Can I improve performance by refactoring SQL commands into classes?

  - by Matthew Jones

  Currently, my entire website does updating from SQL parameterized queries. It works, we've had no problems with it, but it can occasionally be very slow. I was wondering if it makes sense to refactor some of these SQL commands into classes so that we would not have to hit the database so often. I understand hitting the database is generally the slowest part of any web application For example, say we have a class structure like this: Project (comprised of) Tasks (comprised of) Assignments Where Project, Task, and Assignment are classes. At certain points in the site you are only working on one project at a time, and so creating a Project class and passing it among pages (using Session, Profile, something else) might make sense. I imagine this class would have a Save() method to save value changes. Does it make sense to invest the time into doing this? Under what conditions might it be worth it?

• msbuild conversion tool to VS2010

  - by prosseek

  I got vcproj file from QMake (qmake -tp vc win32.pro), and when I run it with msbuild (msbuild for VS 2010), I get the following error. MSBUILD : error MSB4192: The project file ".\win32.vcproj" is in the ".vcproj" or ".dsp" file format , which MSBuild cannot build directly. Please convert the project by opening it in the Visual Studio IDE or running the conversion tool, or, for ".vcproj", use MSBuild to build the solution file conta ining the project instead. I'd like to run the conversion tool for getting VS2010 project file. What's the tool for it?
