class Program
{
static void Main(string[] args)
{
Application app = new Application();
TaskInfos tInfos = app.TaskInfos;
if (tInfos.Contains("Data Flow Task"))
Console.WriteLine("The application contains the Data Flow Task");
}
}
}
Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
Namespace TaskInfos_Item
Class Program
Shared Sub Main(ByVal args() As String)
Dim app As Application = New Application()
Dim tInfos As TaskInfos = app.TaskInfos
If tInfos.Contains("Data Flow Task") Then
