DTSBreakpointHitTest Enumeration

 

Applies To: SQL Server 2016 Preview

Enumerates the values for the hit count types. This class works with the BreakpointTarget class.

Namespace:   Microsoft.SqlServer.Dts.Runtime
Assembly:  Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)

public enum DTSBreakpointHitTest

Member nameDescription
Always

Execution is always suspended when the breakpoint is hit.

Equal

Execution is suspended when the number of times the breakpoint has occurred is equal to the hit count.

Expression

Execution is suspended when the expression changes.

GreaterOrEqual

Execution is suspended when the number of times the breakpoint has occurred is equal to or greater than the hit count.

Multiple

Execution is suspended when a multiple of the hit count occurs.

To add flexibility and power to a breakpoint, you can modify the behavior of a breakpoint by configuring the breakpoint hit count, which specifies the number of times a breakpoint occurs before the run-time engine is suspended, and the hit count type, which contains an expression that specifies when the breakpoint is hit. This value is used in the HitTest property.

Legacy Code Example

The following code example modifies the default value of a BreakpointTarget using this enumeration.

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

namespace Microsoft.SqlServer.SSIS.Samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Package pkg = new Package();
            TaskHost taskHost = (TaskHost)pkg.Executables.Add("STOCK:FileSystemTask");
            BreakpointTargets bptargets = pkg.GetBreakpointTargets(taskHost, false);

            // Get the first breakpoint in the collection.
            BreakpointTargetEnumerator myEnumerator = bptargets.GetEnumerator();
            myEnumerator.MoveNext();
            BreakpointTarget bptFirstOne = myEnumerator.Current;

            // Display the initial values.
            Console.WriteLine("Description              {0}", bptFirstOne.Description);
            Console.WriteLine("Enabled?                 {0}", bptFirstOne.Enabled);
            Console.WriteLine("HitTest                  {0}", bptFirstOne.HitTest);
            Console.WriteLine("ID                       {0}", bptFirstOne.ID);
            Console.WriteLine("--------------------------------------------");

            // Modify the default value of HitTest.
            myEnumerator.Reset();
            myEnumerator.MoveNext();
            bptFirstOne = myEnumerator.Current;
            bptFirstOne.HitTest = DTSBreakpointHitTest.Equal;

            // Display the values again, including the new HitTest.
            Console.WriteLine("Description              {0}", bptFirstOne.Description);
            Console.WriteLine("Enabled?                 {0}", bptFirstOne.Enabled);
            Console.WriteLine("HitTest                  {0}", bptFirstOne.HitTest);
            Console.WriteLine("ID                       {0}", bptFirstOne.ID);
        }
    }
}

Sample Output:

Description Break when the container receives the OnPreExecute event

Enabled? False

HitTest Always

ID -2147483647

--------------------------------------------

Description Break when the container receives the OnPreExecute event

Enabled? False

HitTest Equal

ID -2147483647
