convert the hexadecimal GUID to a string GUID

[Guest Chris]

I have following objectguid as hex guid:

D4 16 D8 5C D0 D6 EC 47 91 89 13 B8 36 74 F3 C1.

 

How to convert it into string GUID format as

xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

 

I found an article (MS KB 325648) to convert string GUID to Hex string form.

But in my case I need to reverse.

 

Thanks.
