The probable problem is that you are retrieving all the rows into your VB app.

Make sure you are not using things like findfirst or vb specific methods,functions that would cause all the data to be retrieved in one go.

I suggest you test the connection in its simplest form first, link a table to datagrid, then try it with a select statement (in the query), then try any VB recordset type operation.
