Adding Fuzzy Lookup Programmatically

I am trying to create a package that reads an input file or input table, does a fuzzy lookup, and outputs results to another table. I was wondering if this can be done programmatically? I have tried adding the fuzzy lookup component like this:

IDTSComponentMetaData90 FuzzyLookupDF = dataFlow.ComponentMetaDataCollection.New();

FuzzyLookupDF.ComponentClassID = "Fuzzy Lookup";

FuzzyLookupDF.Name = "FuzzyLookup";

I wondering how I can change the properties, such as what the input column is, reference table, lookup column, etc? I am not even sure if this can be done; if it can, I'd like some guidance on what the properties I would need to change are.

Thanks!

Please see this topic which describes how to add and configure a data flow component programmatically - it apllies to any component (of course, each component has its own properties):

There is also appropriate sample:

I have read the examples and topics you mentioned. I am able to set certain properties of the fuzzy lookup, such as MatchIndexOptions, ReferenceTableName, MinSimilarity. But I am still not able to set certain things such as JoinToReferenceColumn and JoinType. When I set those in code like this:

instance.SetComponentProperty("JoinType", 2);

I get the following error:

System.Runtime.InteropServices.COMException was unhandled
Message="Exception from HRESULT: 0xC0204006"
Source="Microsoft.SqlServer.DTSPipelineWrap"
ErrorCode=-1071628282

I created a Fuzzy Lookup package I using the SSIS interface, and then looked at the XML format of the package. The properties I could set were part of the "Fuzzy Lookup" component. The ones I can't set are still part of the same component, but under an "OleDbConnection".

Should I still be able to set these connections of the Fuzzy Lookup component? Is there something else I need to add first? I looked at a list of available components that I can use, and I didn't see an OledbConnection in there.

For the obvious reason that its not a property you can set. Only the properties that appear on the properties windows can be changed

You have to study the samples more to get familiar with the design-time logic of data flow components -- how to reference upstream columns and generate output columns. The properties you are mentioning are parts of input columns. They can be set by calling SetInputColumnProperty, but only after the columns are instantiated.

"OleDbConnection" is a placeholder entry for a connection manager this component will use, it should not be related with the properties you are mentioning.

HTH,
