I'm stuck need help

Hi !
i am a novice programmer......trying to code a gnutella clone for my class project..
I am facing trouble with using the GUID in the header....
My problem is :-

a) As the cocreateguid function returns a GUID structure....how do i convert that into a byte array sos that i can send it on it's way....the UUidtostring ()
function is not working for me.....is causing an exception in the application code.

b)Could anyone also please...clarify the purpose the GUID serves and how do i hanlde it in my application.....

----Thanks help will be highly appreciated....

Here is my Guid Code, a function which return a Byte array ..
note that you dont need to use CoCreateguid function!

Code:



Private Function Guid() As Byte()

    

  On Error GoTo HandleError

  

  Dim iPos As Integer

  Dim bTemp() As Byte

  ReDim bTemp(0 To 15)
 

' client guid

  Randomize

  For iPos = 0 To 14

      bTemp(iPos) = CByte((254 * Rnd + 1))

  Next iPos

  bTemp(7) = 255

  bTemp(15) = 0

  Guid = bTemp

  Exit Function

  

HandleError:

  LogError ("Guid")

  Resume Next

    

End Function

Yes it is.. Visual Basic

hi!
Thanks for posting the solution!...I am using VC++..but ur post gave me some new ideas..anyway for those who are using the GUID struct....i think....just copying the struct members into a byte array would suffice....using the wsprintf and a format string consisting of %x...this is pretty dumb....but i think it works...:-)
