My VB Project

Okay here is what I'm trying to do:

I have set up a VB form that should allow the user to open up an Excel document they choose from the form. Then in the VB form the user will specify a column of the Excel sheet they want to search, the row they want to start the search at, and the row they row they want to end on. Once they click the begin search button the VB applicatioin would copy each row from the desired column and paste it into a web search application. If the web applicatioin found anything it would continue the search if it the search didn't find anything it would display a message box with a click to continue type message.

Here's what I have so far:

I have created the interface and have the program running where it will copy the rows of the desired column one by one and paste them into the column row next to the user selected column row.

What I need:

So I need help how to integrate the Internet search into my program and also how to allow the user to select the file that they want to search. I know how to access the Open Dialog control but that's about it. Any help would be appriciated at this point.
