• SQL Server Copy Database with "Transfer Database Task" breaks identity columns?

  Hello all! I'm trying to do something which is seemingly simple, but I keep running into problems, so I am hoping for some friendly advice. I have a live SQL database running on a hosted Sql Server 2000.  I'd like to copy that database to my local machine running Sql Server 2005. What is the easiest way to do this I tried creating a very simple SSIS package with one "Transfer Database Task" which does the database copy.  This almost works, but all of my "identity columns" have been turned off for some reason. Is there a better way to copy a database   Is this "identity" thing a setting I am missing or is it a known issu ...Show All

• .NET Development how to add a network place

• Visual Basic Using process to run a batch file

  I am converting a VB6 app into VB.net. This app checks the existance of source files in RCS by creating a batch file which checks out the source files and copies them to a temporary directory. The app then looks in the temporary directory for the existance of the files. The VB.net version works except that the batch process is copining the files to the Windows directory instead of the temporary directory which was made the default. It creates the batch file itself in the temport directory but doesn't copy the files there. The most current version of the code is below. When I run the batch file in DOS it works fine and when VB6 does it it wor ...Show All
