InteractiveMode Variable

In DTS, message boxes were a great way to debug packages and especially ActiveX scripts. In SSIS, other methods of tracking down issues, such as breakpoints and logging, are the way to go. In fact, message boxes aren't allowed in SSIS unless you are running the packages on a client machine. If you run a package on a server with the following code:

MsgBox("This is a message box!")

You'll see an error message similar to this:

Error: 2008-03-18 23:00:03.30 Code: 0x00000002 Source: Script Task Description: The script threw an exception: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 11:00:02 PM Finished: 11:00:03 PM Elapsed: 0.546 seconds. The package execution failed. The step failed.

If you come across that one user that just can't give up their precious message boxes, you can use this code:

If CBool(Dts.Variables("InteractiveMode").Value) = True Then
MsgBox("This is a message box!")
End If

This will allow the user to see their message box on the client, but repress the error when running on the server!

Upgrading your SSIS Management Framework: Part 3

At this point, you understand the options for moving an SSIS framework to the latest version of SSIS, and you've upgraded the logging portion of the framework using a hybrid approach.  The final step in the framework upgrade is handling your configurations.  Let's walk through an existing configuration implementation and how you can upgrade it by combining your existing implementation with the standard SSIS framework. Overview A typical "old-school" configuration scheme is described in the SSIS PDS book or in this blog post here: .  Starting in SSIS 2012, the configuration scheme uses environments and parameters when using the Project Deployment Model, as discussed here: . In both scenarios, the core ideas in a configuration scheme are: Provide the ability to move packages through environments without having

Manipulating Excel Spreadsheets in SSIS

Tom, an attendee at last weekend’s SQLSaturday Olympia , asked me how to refresh a spreadsheet from within SQL Server Integration Services. My first thought was to turn on the connection’s “Refresh data when opening the file” option in the spreadsheet itself and avoid the situation entirely; however, this may not always be a viable solution. Here are the steps to perform the refresh from within an SSIS package. First, ensure that Microsoft.Office.Interop.Excel is registered in the GAC. If not, install the 2007 Microsoft Office system Primary Interop Assemblies . This will need to be done on any machine where you plan on running this package. Next, create a script task in your SSIS package that contains the following code (include your spreadsheet name): Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Runtime Imports Microsoft.Office.Interop.Excel Public Class ScriptMain Public Sub Main() Dts.TaskResult = Dts.Results.Success Dim excel

Reporting Services 2008 Configuration Mistake

To start working with the management side of SQL Server Reporting Services 2008, I decided to set up a report server and report manager. Unfortunately, I made a mistake while setting up my configuration that left me a little perplexed. Here are the steps I took to cause, track down, and solve the issue. Problem: I began by opening the Reporting Services Configuration Manager from the Start Menu. I clicked through each of the menu options and accepted the defaults for any question with a warning symbol, since warning symbol typically designate an action item. After two minutes, all of the warning symbols had disappeared, and I was ready to begin managing my report server. Unfortunately, opening up a browser and trying to open up the report manager resulted in the dreaded " The report server has encountered a configuration error. (rsServerConfigurationError) " message. Sherlock-ing it: I put on my sleuthing hat and went to the log file directory: C:\Program Files\Microsoft
