How to: Embed an External Item Picker Control in an InfoPath Form

i am doing an experience based on the above MSDN article. though the article
had a dedicate table to explain each fields that need to be filled in the External
Item Picker Properties window. I spent a bit of time to figure out those fields
mapping with BCS residing in the sharpeoint Server. i had attached the picture
to show how they should match.. I hope this post can help to quickly setup
the External Item Picker Control in the InfoPath form

• Fill the ECT Namespace (External Item Picker Field) field with Namespace (External Content Type Field).
• Fill the ECT Name (External Item Picker Field) field with Name (External Content Type Field).
• Fill the System Instance Name (External Item Picker Field) with External System (External Content Type Field).
