I only have c# installed here but it should be easy to port from:

 DataSet1 ds = new DataSet1();
 BindingSource bindSource = new BindingSource();
 bindSource.DataSource = ds;
 bindSource.DataMember = "DataTable1";
 this.dataGridView1.DataSource = bindSource;

sorry forgot to add you can use filter for the same effect as doing a select.

bindSource.Filter = "MyColumnName > 5";

You can also perform a linq-query to get your result from the datatable into your datagridview.

Example:
Dim Query = From i In YourDataTable.AsEnumerable() _
         Where i.Field(Of String)("YourField") = "Status"

DataGridView_Customer.DataSource = Query.AsDataView()
