• Software Development for Windows Vista Reusing workflows in a State machine

  I have a state machine with states A and B. Both of them have an EventDrivenActivity which has the same sequential workflow. What is the best way to create just one copy of this workflow instead of repeating under both EventDrivenActivities Note that there are other EventDrivenActivities on each state which make them truely different, so combining the two states into one is not an option.

• Visual Studio Tools for Office Action Pane disappears

  I have an Excel Template solution developed using VSTO 2005 that has controls on the Action Pane. I have a custom menu button that the user can use to toggel the Action pane on and off, and everything works fine until the user attempts to open an additional Excel file. If a user opens another Excel file from Windows Explorer by double clicking or selecting open from the context menu, the Actions Pane goes away. I then switch back to the original VSTO document, and using my menu button attempt to restore the action pane. The code displays the paction pane, but now all of my controls are missing. Here is the code the I use to toggel the v ...Show All

• SQL Server SQL Server 2000 and 64Bit Operating System

  We are in the process of upgrading many of our servers to HP Blades. We currently run SQL Server 2000 on an old Compaq with Windows 2000 Server as the OS. Our new blades have 64bit Processors. We want to go ahead and take advantage of the additional processing power of the new servers but cannot migrate to SQL 2005 at this time.
