I am trying to call a Net.TCP WCF service within my SSIS package. I have set up the script component, changed the .NET Framework to 3.5 in the Service Reference. I am creating the sample package based on the example provided in the below link.
How to Configure an SSIS Package to Access a Web Service using WCF
The link states to override the PreExecute method but I am unable to find the method within the script component in SQL 2008 R2.
The script component in my package begins with the following code:
[System.AddIn.AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
However, the example written in the above-mentioned article has the below code:
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
I've tried just copying the code across then to fix the relevant references but no where does it contain a reference for UserComponent.
Could someone point out what am I doing wrong here?
Cause of the issue:
You are using the Script Task available on the Control Flow tab instead of the Script Component transformation available within Data Flow Task.
SSIS 2008 R2 package illustrating the differences:
Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_10121670.dtsx.
BIDS will be default display the Control Flow Tab. From the toolbox, drag and drop Script Task and Data Flow Task as shown below.
Double-click Script Task to view the Script Task Editor. On the Script Task Editor, click Script page and then click Edit Script...
Integration Services Script Task code editor will open. You will notice that the class ScriptMain inherits from Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
The example it the MSDN article does not use this Script Task.
On the Control Flow tab, double-click Data Flow Task to switch to the Data Flow tab. Drag and drop a Script Component from the Data Flow Transformations section on the Toolbox.
When you drag and drop a Script Component, the Select Script Component Type dialog will appear. You have to choose the appropriate one that suits your requirements. This sample sets the type to Source so we can view the script editor. Click OK.
Double-click the Script Component to view the Script Transformation Editor. On the Script Transformation Editor, click Script page and then click Edit Script...
Integration Services Script Component code editor will open. You will notice that the class ScriptMain inherits from UserComponent. This is the component that you need to use to practice the WCF sample code in the MSDN blog article.
You can see the PreExecute method inside the Script Component code that you have been looking for.

I have an SSIS package that contains a script task component, I did some coding inside to do data manipulation, it was working before but all of a sudden I can no longer open the VSTA code when clicking edit.
I am using Visual Studio Community 2017 for developing SSIS packages and I use SQL Server 2016.
Some of components are not in SSIS Toolbox.
This is that I have now:
and this is my colleges have(They don't have the same version of Visual Studio that I have):
For example: I need to add a XML Source component to one of my Data Flow but there is not anymore in Other Sources sector in SSIS Toolbox.
I tried to add the missing components (Tools -> Choose Toolbox Items ->) but I don't have the tab for SSIS component.
How can I add those components (For example XML Source) to my Toolbox?
I have found the cause of this problem.
By changing the TargetServerVersion to SQL Server 2016 in Project properties. My project has been converted and now i have this component in my ToolBox.
Now, I have XML Source component in my SSIS ToolBox.
I can confirm the answer given by Ardalan Shahgoli resolved my missing component. I have captured a screenshot demonstrating the problem and the resolution. In my example, I was missing a component 'Excel Source Plus' from the 'CozyRoc' addin
PROBLEM:
Missing some components. The data flow has the component on the canvas, but there are of error messages in the Error List window, and you are unable to edit the component. For example, you might see an error message such as this:
Severity Code Description Project File Line Suppression State
Error Validation error. Alt Data Flow_Merge Data Task: Alt Data
Flow_Merge Data Task: The component metadata for "Lookup Plus, clsid
{8DC69D45-2AD5-40C6-AAEC-25722F92D6FC}" could not be upgraded to the
newer version of the component. The PerformUpgrade method
failed. SSASUsageStats.dtsx 0
RESOLUTION:
Changing the TargetServerVersion will effect which components are available in the 'SSIS Toolbox'. As seen in the screenshot, there are tons more components after changing the project property TargetServerVersion. For example, 'Excel Source Plus' is found. The Data Flow canvas now has an image by the icon. And the component now has an 'EDIT' option.
This is not the same as debug mode. I want to display a warning if the developer is actually in BIDS and not display the warning if the package is being run from a scheduled job.
You could use a script task that opens a MsgBox. The MsgBox would only open when the task is running in BIDS, if I am not mistaken.
I'm afraid what you are trying to achieve is not possible. BIDS uses the same runtime as your SSIS agent.
You could, however, set an environment variable in your package and remove it during deployment. All of this is hacky and defeats the purpose though.
There really should be no custom logic when running a package locally versus being deployed (other than configurations that might affect the execution graph).
If you are trying to prevent user-error it would be best to educate your peers and/or restrict access.
I have found but not checked that there is a system variable "System::InteractiveMode" that may be used for this. Something to check.
According to Microsoft's documentation on System Variables the InteractiveMode variable should be able to fulfil your need to determine if the package is running from BIDS or from a SQL Job.
InteractiveMode (Boolean)
Indicates whether the package is run in
interactive mode. If a package is running in SSIS Designer, this
property is set to True. If a package is running using the DTExec
command prompt utility, the property is set to False.
I created a Script task at the beginning of my Flow (in the control flow tab) with a precedence constraint on the following task. I defined System::InteractiveMode in the ReadOnlyVariables field and used the code below to display the question and process the answer.
public void Main()
{
if ((bool)Dts.Variables["InteractiveMode"].Value)
{
DialogResult button = MessageBox.Show("Are you sure you want to run the package?", "Validate", MessageBoxButtons.YesNo);
if (button == DialogResult.No)
{
Dts.TaskResult = (int)ScriptResults.Failure;
return;
}
}
Dts.TaskResult = (int)ScriptResults.Success;
}
It doesn't stop the execution like the stop button in BIDS but prevents the execution of the rest of the package. I tried to use the RunningPackage.Stop() method but in order to get the list of RunningPackages it requires to be running from SQL Server Integration Service.
I tested it from BIDS and from SQL Server integration service and it worked as expected.
I'm creating a new SSRS report in AX2012. At first, I added some Data Methods through Visual Studio, but later I found another way to get what I wanted without using those data methods. Consequently, I deleted the Data Methods and the Business Logic project.
Now, everytime I build the report, I get a warning :
Could not resolve 'projectname' from the AOT. If the reference is required in your code, you may get compilation errors.
How do I delete the reference to the business logic project? My report runs without problems, but I would like to stop getting this warning...
Thanks!
It should just be a project dependency.
See here: https://msdn.microsoft.com/en-us/library/et61xzb3.aspx
To remove:
In Solution Explorer, select a project. On the Project menu, choose
Project Dependencies. The Project Dependencies dialog box opens. On
the Dependencies tab, select a project from the Project drop-down
menu. In the Depends on field, clear the check boxes beside any other
projects that are no longer dependencies of this project.
EDIT: Another option is to export the XPO and edit it in there, and reimport.
In my Project, I want to create one empty text file when the package triggered.
I'd probably just use a one-line Script task.
System.IO.File.Create(#"C:\OneEmptyTextFile.txt");
On your Control Flow, drag a Task of type Script Task from your SSIS Tool Box
Double click on the new Script Task
In the Script Task Editor, click Edit Script...
In the public void Main() section, where it states // TODO: Add your code here replace that line with the above code. If you are using SSIS 2005 or if you have chosen to use VB.NET in 2008/2012, please remove the trailing semicolon.
Click the X button in the upper right corner of the Integration Services Script Task window
Back in the Script Task Editor, click OK.
Now whenever that Task runs, it will use the static Create method of the File object to create a file in the requested location.
It might be good idea to dispose of the FileStream object after using the File.Create method to avoid locking issues.
