Examples
The following code sample, implemented in a console application, adds a ScriptTask to the package and displays the default values of some of its properties.
using System;
using Microsoft.SqlServer.Dts.Runtime;
namespace ScriptTaskCS
{
class Program
{
static void Main(string[] args)
{
Package pkg = new Package();
string newLine = System.Environment.NewLine;
Executable exe = pkg.Executables.Add("STOCK:ScriptTask");
TaskHost thTask = (TaskHost)exe;
string taskInfo;
taskInfo =
"Entry point: " +
thTask.Properties["EntryPoint"].GetValue(thTask) + newLine +
"Script Language: " +
thTask.Properties["ScriptLanguage"].GetValue(thTask) + newLine +
"ReadOnlyVariables: " +
thTask.Properties["ReadOnlyVariables"].GetValue(thTask) + newLine +
"ReadWriteVariables: " +
thTask.Properties["ReadWriteVariables"].GetValue(thTask);
Console.WriteLine(taskInfo);
Console.Read();
}
}
}
Imports Microsoft.SqlServer.Dts.Runtime
Module Module1
Sub Main()
Dim pkg As New Package
Dim newLine As String = System.Environment.NewLine
Dim exe As Executable = pkg.Executables.Add("STOCK:ScriptTask")
Dim thTask As TaskHost = CType(exe, TaskHost)

Remarks
The ScriptTask class defines the Script task and handles the interaction of the Script task with the runtime and with Visual Studio for Applications.
For more information, see Script Task and Coding and Debugging the Script Task.
Constructors
ScriptTask() |
Initializes a new instance of the ScriptTask class. |
Properties
BreakpointManager |
Gets the BreakpointManager used for controlling breakpoints on this task. |
Breakpoints |
Gets an array of breakpoints set on this task. |
DebugMode |
Gets or sets a value indicating whether the task is running in debug mode, and whether it should raise the OnBreakpointHit(IDTSBreakpointSite, BreakpointTarget) event while the task is running. |
DefaultActiveItem |
Gets the default script. |
EntryPoint |
Gets or sets the name of the class that is executed as the entry point. |
ExecutionValue |
Gets a user-defined object. This field is read-only. |
ProjectTemplatePath |
Gets the path of the specified project template. |
ReadOnlyVariables |
Gets or sets the comma-delimited list of existing variables made available to the package by the user for read-only access. |
ReadWriteVariables |
Gets or sets the comma-delimited list of existing variables made available to the package by the user for read/write access. |
ScriptingEngine |
Gets the VSTATaskScriptingEngine class. |
ScriptLanguage |
Gets or sets the programming language in which the script is written. |
ScriptLoaded |
Gets a value indicating whether the task contains custom script. |
ScriptProjectName |
Gets or sets the name of the script project. |
ScriptStorage |
Gets the VSTAScriptProjectStorage for the script. |
SuspendRequired |
Gets or sets a Boolean indicating whether a task should suspend execution when the task encounters a breakpoint. This value is set by the run-time engine for tasks and containers when a breakpoint is encountered. |
TargetServerVersion | (Inherited from Task) |
Version |
*** Member deprecated; see Remarks. *** Returns the version of the task. This property is read-only. (Inherited from Task) |
Methods
AcceptBreakpointManager(BreakpointManager) |
Passes a BreakpointManager to the task. This method is called by the runtime and is not used in code. |
CanUpdate(String) |
*** Member deprecated; see Remarks. *** A Boolean that indicates whether the new package XML can update the old package XML. (Inherited from Task) |
Equals(Object) |
Determines whether two object instances are equal. (Inherited from DtsObject) |
Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object) |
Executes the script contained in this instance of DTS Script Task. |
Finalize() |
Releases all resources used by the ScriptTask. |
GetConnectionID(Connections, String) |
Gets a String containing the ID of the connection. (Inherited from Task) |
GetConnectionName(Connections, String) |
Gets a String containing the name of the connection. (Inherited from Task) |
GetHashCode() |
Returns the hash code for this instance. (Inherited from DtsObject) |
InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker) |
Initializes the properties associated with the Script task. This method is called by the runtime and is not used in code. |
LoadFromXML(XmlElement, IDTSInfoEvents) |
Implements loading of properties from XML document. |
ReportBreakpointChanges() |
Reports the breakpoint changes from the task. |
ResumeExecution() |
Resumes execution of the task or container by the run-time engine after pausing. |
SaveToXML(XmlDocument, IDTSInfoEvents) |
Implements saving of properties to XML document. |
SetUniqueScriptProjectName() |
Sets the unique name of the script project. |
SuspendExecution() |
Indicates that the executable must suspend execution. This method is called by the run-time engine. |
Update(String) |
*** Member deprecated; see Remarks. *** This method updates the old package XML with the new package XML if CanUpdate(String) is set to true. (Inherited from Task) |
Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging) |
Verifies that the component is correctly configured. |
