error C2065: 'StreamReader' : undeclared identifier

Add this:

using namespace System::IO;

error C2065: 'inData' : undeclared identifier
error C2227: left of '->EndOfStream' must point to class/struct/union/generic type

These happen because of the StreamReader problem.

The following isn't in your list, but it'll come up:

error C2039: 'searchResult' : is not a member of 'Hardware_Store::Form1'

The member is searchResults, note the plural. Change it in the few places it's not right.
