What is the best way to modify a [fairly large] VB 2008 project which connects to an Access database via OleDb to connect to an SQL Server 2008 Express (via SqlCllient) database instead? I tried doing a find-and-replace throughout the entire project from ".OleDb" to ".Sql" and from "OleDb." to "SqlClient.", but it didnt work :) HUNDREDS of errors!!! Is there an easy way of doing this or am I going to have to rewrite the entire application? There a re a few thousand lines of code over about 60 forms :(

Mmmm... for that reason is highly recommended to use layer architecture when designing & programming... if your data access code would be written & coded only in one layer (class library project), you'll only need to do the changes there without modifying any other code... So I recommend to you strongly use this approach in your future developments.

>> HUNDREDS of errors!!!
Did you select in the find-and-replace window to work on hidden text also ? It's normal to give some errors but not too many ... or you have used the wizards to fill some controls ?

Also, there is an additional problem. How are you accesing the data in MS Access database? Via Queries, or directly with SQL written in your source code? Note that SQL syntax is different between MS Access SQL and Transact SQL of SQL Server.

Thanks for all the replies. jpaulino, yes I did select to work on hidden text. RolandDeschain, in some parts I access the data via SQL queries (executing an OleDbCommand connected to an OleDbConnection). Other places I simply drag-and-dropped a table from Visual Studio's "Data Sources" window onto the form. This automatically created a DataGridView with a TableAdapters and BindingSources. The DatagGridView is database-agnostic, but I'm not so sure about the other two. I'm beginning to think I might have to rewrite the whole damn thing :(

I have used the wizards !!! This way you have to change it manually. I suggest that you don't use it again and do that in the code.
