Move your wildcards (i.e. your % characters) into your VB.net string before you pass it as a parameter.
For example, do this in VB.net code...
sqlComm.Parameters.AddWithValue("@search", "%" + info.search + "%");
And in your SQL when you use the @search parameter in the LIKE statement, don't add in wildcards, like shown below...
WHERE building LIKE @search
See this SO post which is essentially the same question...
