Hello All, I am trying to access the document schema properity of the disassimbler. I have looped thru the header context props and don't see that it is present. How and I get and set the document schema header in a custom componet before it's processed by the default disassimbler.
You are not able to "get" the document schema before the message is processed by a dissasembler. Retreival of this context property is exactly the task of the dissasembler component. You might be able to set it though...

Christof, I am able to retreave the document schema, but not sure how to set it or where? What interface would I use?

To set the schema, you can use the following code:
string systemPropertiesNamespace = "http://schemas.microsoft.com/BizTalk/2003/system-properties"; string messageType = "<your schema namespace here without the <>>#< your schema root node here>"; msg.Context.Promote("MessageType", systemPropertiesNamespace, messageType);

Gilles, This sets the messageType properity on the message, Should that also set the pipeline's schema / message type too? I'm trying to read in many flat file types into one pipeline and route the data based on a generic header record. So I have to be able to change the pipeline's document schema at runtime via a custom pipeline. How can I change the Document schema at runtime?

I assume you are currently using the flat file disassembler. In this case, you will have to write a custom disassembler that extends the out of the box, sniffs the content of the flat file and figure out the schema you want to use. Then promote the property.
I am in the process of writing an example of this on my blog but the roadmap above should get you going.
