I'm confused.The article seems to be about using the SSIS instalation that comes with SQL Server 2005. However, the links out to the Microsoft web site reslove to pages that deal with SQL Server 2008, which is quite a different product.

I'm using a VERY simple script that works to change my flat file connection path but can't get the syntax to set the DataRowsToSkip property of the connection. To change the path I'm using:Dts.Connections("ReturnDataFile").ConnectionString = Dts.Variables("FullPath").Value.ToStringHow would I change the datarowstoskip for an integer variable HEADR:Dts.Connections("ReturnDataFile").Properties("DataRowsToSkip") = Dts.Variables("HEADR").Value?????????????Thanks,Joe B

Hi Padmaja, Thank you for posting the code. But, I still have a problem while loading the header array. Below is my codePublic Class ScriptMain Sub Main() ' Create a package and add a Data Flow task.

But When I am trying to pass the column names using a variable like:( Dim headers As String() headers = Split((Dts.Variables("col1").Value.ToString), ","), it throws the following errorError: The script threw an exception: Exception from HRESULT: 0xC0010009,DTS_E_ELEMENTNOTFOUNDPlease let me know, where am I going wrong

After reviewing the article, I think it is probably an excellent article . . . if I wanted to create the SSIS package in a .NET language. However, since I find writing a program in order to program an SSIS package to be, IMHO, taking the longest possible route to get from point A to point B, I believe that the title of the article is misleading. THe title should be something more like "Programming an SSIS Package in .NET".

What I expected, from the title, was an article on developing an SSIS package from within BIDS. Needless to say, I was disappointed; howver, I will add this to my Briefcase on the off chance that I may need to perform a similar task.

Ram:

I have given the assemblies to be referred in the article itself (see 3.Getting started)

AndreQ1:

You could combine the common (or default) settings into functions and can then be called appropriately.

For simple file transfers, DTS and SSIS may not differ much. When it comes to Transformations, SSIS provides many new features when compared to DTS. You can have a look at MSDN for the different Transformations supported in SSIS. Hope that helps.

AndreQ1-315878 — Mon, 11 Jun 2007 14:05:00 GMT

Given the great detail that's possible, and may be required, would it be possible to create additional libraries of functions that have many defaults set up. For example, the code below (taken from your article) would appear to be used for most text data files:

cnFile.Properties("ColumnNamesInFirstDataRow").SetValue(cnFile, True)cnFile.Properties("DataRowsToSkip").SetValue(cnFile,0)cnFile.Properties("RowDelimiter").SetValue(cnFile,vbCrLf)cnFile.Properties("TextQualifier").SetValue(cnFile,"""")cnFile.Properties("HeaderRowsToSkip").SetValue(cnFile, 0)cnFile.Properties("HeaderRowDelimiter").SetValue(cnFile,vbCrLf)cnFile.Properties("CodePage").SetValue(cnFile,1252)

It is not yet apparent to me the benefit of this technique over DTS for the majority of file transformations.

Let me know if my reasoning on this issue makes sense.

Thanks

Ms. Padmaja!

First of all, an exemplary topic.

As you mentioned, I would like to use other approach that is to use the API to create, configure and run packages from own applications.

I am using C#. What DLLs I must add it to this?

Thanks and looking forward to hear from you.
