• SQL Server package detect that instance is already running?

  Folks, I have a package scheduled to run every hour. Users have asked if, in addition to the scheduled run, they can have it so that they could dump a file into the input directory and then kick-off the package immediately. Problem is that things fail if they try to start the package when the scheduled instance of the package is still running. Is there any way that the package could check to see if an instance if itself is currently executing and refuse to execute if there IS an instance running PJ Hi Michael, Currently I'm just piloting this by getting users to go to SQL Server Agent in the management studio, right clicking on the job and selecting "Start Job at step.." ...Show All

• Visual Studio 2008 (Pre-release) Forcing refresh of a Window object

  Hi at all I want to ask, if it is possible to force a repaint on a wpf Window object With WinForms there is possible to call Refresh() on a Form object. Is there a similar method to do this on the Window object Thanks for answering. Thanks for your tips. I tried it out and it should work for my intention. I read the section about threading and i also tried a solution with Delegate.BeginInvoke. But the problem is that i need to create a new UI component in the second thread (this is the time time consuming part which throws events which have to be displayed in the first window component) and this leads to an exception because the second thread is MTA and not STA. That was the problem with this solution. ...Show All

• Software Development for Windows Vista Subscription service and persistence service

  I've implemented a custom subscription service that inherits from WorkflowSubscriptionService. I have a state machine workflow that's been published as a web service. In my workflow I have a CallExternalMethod activity that sends an e-mail message, and a HandleExternalMethod activity that listens for incoming e-mail. I'm using my subscription service to get the WorkflowInstanceId based on a message ID that I embed in the e-mail message. I've tested this and traced my workflow and everything works. When my workflow sends out the e-mail, it calls CreateSubscription on the subscription service. When the event is received, it calls DeleteSubscription. This would seem to be the correct behaviour. Then I added the SQL persistence service a ...Show All

• SQL Server SSRS Security issues following upgrade to 2005

  We've recently installed SQL2005 with Reporting Services on a 64bit server, and migrated the old ReportServer database from SQL2000. All seemed fine, except we get some security related errors. Firstly when you try and change any of the item or system level role definitions, an internal error is displayed, e.g. An internal error occurred on the report server. See the error log for more details. (rsInternalError) Conversion failed when converting the nvarchar value 'System Administrator ' to data type tinyint. Also, the ReportServerService log files continually generate loads of the following errors for different catalog items: ReportingServicesService!library!15!30/08/2006-14:54:12:: Error on upgrade Upgrade ...Show All

• Visual Basic COM interop using exe instead of dll

  hello, i have a program that is used both as an exe, and as a COM dll instantiated in a VB6 program. maintaining this has been a pain in the butt, so i would like to know how i can just use the exe and not have to compile the dll at all. i have made my exe COM aware, but everytime i try to instantiate it i get an error. do i have to use regasm to accomplish this task all th docs discuss dll's, and do not explain anything about exe's. please give an example if possible.
