How do I call a SQL Server 2000 DTS package in VB.net

Question

How do I call a DTS from a VB.net application?

Answer 1

This is a pretty crude set of classes that should do what you want if you want programmatic control over a DTS package from VB.Net. I make no guarantees over it's correctness or reliability but it should give you enough pointers to get started.

Just add a reference to the DTSPackage Object (COM) Library to your Visual Studio project

Option Explicit On

Option Strict On

Answer 2

If you are referring to Data Transformation Services that is part of sql server 2000 (not available in later version as it was replaced with integration services) then there are a few ways.

You can run it from DTSRun if your app is on the server using process.start

process.start("dtsrun /S ""server name"" /U sa /N ""d:\task.dts""")

If it is not on the server you can still useDTSRun but inside a stored procedure that you call using master.dbo.xp_cmdshell, Then call the SP in your code. (Although if you use xp_cmdshell you must be aware of the security risks of opening up).

Alternatively you could look at this article it explains how to do it from vb script but the code could easily be converted.:
