• Software Development for Windows Vista Trouble with WebService and Persistence

  Hello all, I'm newer to the workflow world and I have a few questions : First, a little background: I've currently got a very simple sequential workflow wraped in WebServiceInput and WebServiceOutput and all interfaces and everything are setup correctly.  I use the publish as web service option and all is well. I then try to execute the web service using the "Invoke" button that is on the default web service form:  I then get this error: System.InvalidOperationException: The workflow hosting environment does not have a persistence service a ...Show All

• SQL Server How to detach properly using SQL Server Express?

  It’s easy to attach a database file in the connection string using AttachDbFilename . And that file gets closed when all connections to that database are closed (one might have to clear the connection pool, or set the connection to use master ). The database file can now be moved or deleted. Sounds good... ...but that database still shows up in the attached databases! (select * from sysdatabases). So over time one could end up with hundreds of attached databases (especially if an application uses the attached databases like document files that users open and close frequently). Question 1: Is there a performance hit having h ...Show All

• .NET Development Network access for a web app

  Hi all, I have a web app that I am developing that retrieves a list of the computers on the network and then displays their date of last reboot. It works fine while on my computer in the dev environment, however if I try to use it from another computer I only get my computer's info. After some work I have found that when I call If (PerformanceCounterCategory.Exists("System", Machine)) I get an unauthorized access issue. I’ve added [assembly: PermissionSetAttribute(SecurityAction.RequestOptional, Name = "LocalIntranet")] But I only get a login box now which is just horrible. I currently have the web app set to Imperson ...Show All

• SQL Server SSIS Dataflow vs SQL2K DDQ

  I am trying to recode a SQL2K DDQ into an SSIS Dataflow. I have no issue recoding it in SSIS except I am not sure that I am doing it correct way. My DDQ has source,destination, update/delete/insert statements and few lookups. I have used activex script for the transformation because I have atleasst 10 If conditions.
