I need help on a project which requires me to make use of Expression Blend & WPF to create a software that can: 1. accept & analysis user ink input 2. search library/source/database for similar shape/character 3. display 4 results found 4. display user's choice on textbox In case I didnt make myself clear, think of it as iPhone's chinese character writing software. Just that in my case im using some image symbols instead of chinese language. Im using Visual Studio 2008 & Expression Blend 2.
