Geocoding

Hello,

I am ignorant about geocoding. I have knowledge on how it works. My question is I have a shape file that lat/long locations along with address in the file including zip. I am trying to build a viewer application with functionalities like geocoding and geoprocessing. When using geocoding funcitonality in viewer will the shape file that I have will work or do I need to geocode again using arcmap. I am confused. Please help

Thanks
