WebServiceTask.DebugMode Property

Artykuł
12/03/2008

Gets or sets a Boolean that indicates if the task is in debug mode. The DebugMode property can be accessed by multiple threads at the same time. To ensure thread safety and avoid concurrency problems, the Interlocked class from the Microsoft .NET Framework is used.

Namespace: Microsoft.SqlServer.Dts.Tasks.WebServiceTask
Assembly: Microsoft.SqlServer.WebServiceTask (in microsoft.sqlserver.webservicetask.dll)

Syntax

'Declaration
Public Property DebugMode As Boolean

public bool DebugMode { get; set; }

public:
virtual property bool DebugMode {
    bool get () sealed;
    void set (bool value) sealed;
}

/** @property */
public final boolean get_DebugMode ()

/** @property */
public final void set_DebugMode (boolean value)

public final function get DebugMode () : boolean

public final function set DebugMode (value : boolean)

Property Value

true if the task is in debug mode; otherwise, false.

Remarks

The Interlocked class provides atomic operations for variables that are shared by multiple threads. The threads of different processes can use this mechanism if the variable is in shared memory. For more information, see Interlocked and Interlocked Class in the .NET Framework Class Library.

The IsBreakpointTargetEnabled function is called each time the task encounters a breakpoint in its code. Because calling the function IsBreakpointTargetEnabled to see if the breakpoint target is enabled is expensive when called repeatedly, the DebugMode flag is used to indicate if the executable is to be debugged. When this flag is set to false, the task can avoid the call to check for an enabled breakpoint. A value of true indicates that the task should check for enabled breakpoints, and is when the IsBreakpointTargetEnabled is checked.

Example

The following code example creates a WebServiceTask, shows the default settings of the properties, including the DebugMode, using the TaskHost. It then sets two fields to show how to set field values.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.WebServiceTask;

namespace Microsoft.SqlServer.SSIS.Samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Package pkg = new Package();
            Executable exec1 = pkg.Executables.Add("STOCK:WebServiceTask");
            TaskHost th = exec1 as TaskHost;

            // List the default values of the Web Service task
            // using the Properties collection of the TaskHost.
            Console.WriteLine("Connection        {0}", th.Properties["Connection"].GetValue(th));
            Console.WriteLine("DebugMode         {0}", th.Properties["DebugMode"].GetValue(th));
            Console.WriteLine("OutputLocation    {0}", th.Properties["OutputLocation"].GetValue(th));
            Console.WriteLine("OutputType        {0}", th.Properties["OutputType"].GetValue(th));
            Console.WriteLine("OverwriteWsdlFile {0}", th.Properties["OverwriteWsdlFile"].GetValue(th));
            Console.WriteLine("ServiceName       {0}", th.Properties["ServiceName"].GetValue(th));
            Console.WriteLine("SuspendRequired   {0}", th.Properties["SuspendRequired"].GetValue(th));
            Console.WriteLine("WebMethodInfo     {0}", th.Properties["WebMethodInfo"].GetValue(th));
            Console.WriteLine("WsdlFile          {0}", th.Properties["WsdlFile"].GetValue(th));

            Console.WriteLine("--------------------------");
            // Show how to set a property using the TaskHost Properties.
            th.Properties["OutputType"].SetValue(th, DTSOutputType.File);
            th.Properties["OverwriteWsdlFile"].SetValue(th, true);

            Console.WriteLine("New value of OutputType and OverwriteWsdlFile: {0}, {1}", th.Properties["OutputType"].GetValue(th), th.Properties["OverwriteWsdlFile"].GetValue(th));
        }
    }
}
