VBA macros do not support 64-bit processors. For more information, see Using Variables in the Script Task. Visual Studio Tools for Application supports creating and loading 32-bit, 64-bit, or bit-neutral (runs in either a 32-bit or a 64-bit process) add-ins.

Variables of both types are accessed in code through the Variables property of the Dts object. You can enter comma-delimited lists of existing variables as the values of these properties to make the variables available for read-only or read/write access within the Script task code. ReadOnlyVariables and ReadWriteVariables Properties If you change the name of the method in the VSTA project, you must change the value of the EntryPoint property.
The ScriptMain class is the default class generated by the script templates.
The EntryPoint property specifies the method on the ScriptMain class in the VSTA project that the Integration Services runtime calls as the entry point into the Script task code. To set the default script language for Script tasks and Script components, use the ScriptLanguage property on the General page of the Options dialog box. After you create a script in the Script task, you cannot change value of the ScriptLanguage property. Microsoft Visual Studio Tools for Applications (VSTA) supports the Microsoft Visual Basic or Microsoft Visual C# programming languages. For more information, see Program VSTO Add-ins. The Application field returns a Application object that represents the current instance of InfoPath. The Script page of the Script Task Editor displays the custom properties of the Script task. To access the InfoPath object model from an Office VSTO Add-in created by using Office development tools in Visual Studio, use the Application field of the ThisAddIn class in your project. On the General page of the Script Task Editor, you assign a unique name and a description for the Script task. Unlike earlier versions where you could indicate whether scripts were precompiled, all scripts are precompiled beginning in SQL Server 2008 Integration Services (SSIS).
