• Smart Device Development rtti enabled and /EHsc

  I'm trying to build an MFC application with c++ (synchronous) exceptions and rtti enabled. It is a port of an application written with evc4.0 (sp4).

• SQL Server Why does "Add Existing Package" make a copy of the dtsx?

  How do we sync up dtsx files with Visual Source Safe best practices Each team member needs to create .dtsx files and add to the same project. When we do "Get Latest Version", other team member's dtsx files are obtained (which is good). But, when we do "Add Existing Package" in Business Intelligence Development Studio, it makes a copy of the existing dtsx file (Example, mypackage.dtsx becomes mypackage(1).dtsx ). Is there another way of adding existing .dtsx files   Jamie - It does work if you specify the absolute path to a package inside project file i.e., myProject.dtproj) instead of just a package name.
