Hi,
Thank you.

I tried out the code (code posted here and also from Jimmy one), and found that it is not generated in sequence as well. The way I test is

1. Defined an array contains 5 elements.
2. Call the COMBGuid 5 times and assigned the return value to each element accordingly 0..1..2..3..4..5
3. Copy the guid value of each array elements to guid column of each record in table.
4. ORDER the guid column

Result, the sequence of record doesn't same as the order of array element.

Is it the right way to test?

Please advice. Thank you
