• SQL Server SQLEXPR_ADV.EXE does not detect WinXP SP1

  Running SQLEXPR_ADV.EXE against Windows XP SP0 causes the setup to exit gracefully with a message indicating the the right service pack is not installed. However, running SQLEXPR_ADV.EXE against Windows XP SP1 does not exit and continues to install. Then, when you try to run a script against the installation, you get the message: [Microsoft][ODBC SQL Server Driver][DBMSLPCN][SQL Server does not exist or access denied]. This will become very problematic when installing SQL Server Express as the database for small installations. The setup really needs to be updated to look for all the system requirements that it can detect. Evident ...Show All

• Visual Studio Express Editions Command Line args question

  I have this program (actually 2) a tray app and the main app. There are settings the user can change to change the behavior of the tray. for example when the tray is running and a camera device is inserted, the user can have it auto launch the main app. (that is simple (Process.Start("PROGRAM.EXE") But there is another option (if auto launch main app if camera is inserted) that it will auto copy photos with no user interaction needed. So the tray looks for the camera every 3 seconds (will that slow the pc down ) and if they have the setting enabled it will auto copy.

• Visual Studio 2008 (Pre-release) Canvas, Rectangles, ClipToBounds slowness

  We are thinking about starting a new moderately complex graphical application in WPF. But before committing to the platform, we are testing features to see if WPF can handle it. >:) One test application so far has a Canvas with ~800 Rectangles (added with C# using “canvas.Children.Add(..)”. These rectangles are movable by dragging them… implemented with Canvas.SetLeft(rect, newLeft) and Canvas.SetTop(..) from the MouseMove handler. I need some tips on how to speed this up. Currently dragging a single rectangle around causes 100% utilization with 20 FPS on a Xeon 2.8GHz… even turning down to 50 rectangles seems ...Show All
