Använd parametrar i dina frågor:

cmd.Parameters.AddWithValue("@Description", "something");
cmd.Parameters.AddWithValue("@ID", 123);

Och motsvarande i VB.net:

// VB.net
Dim cmd As New SqlCommand("UPDATE Products SET description = @Description WHERE id = @ID")
cmd.Parameters.AddWithValue("@Description", "something")
cmd.Parameters.AddWithValue("@ID", 123)
