Excellent utility, thanks. I'd like to update our code to the current VBFLXGRD18, and see that the utility only goes to 17. I see where you are using this in Set_xx_Flex, but in looking at the GUIDs in Krool's post for 18, I see four CLSIDs instead of three (which I can confirm for the prior versions). So, I'm afraid I must ask for a bit of help. Thanks, and happy new year!
