Is there any way to automatically generate a GUID programatically ?  If so how ?

I would be grateful for all advice offered.

Thanks in advance

Use the CreateClassID function and add ComObj to the uses clause.

or coCreateGuid from ole32.dll :

Uses comobj;//for GuidToString function

function CoCreateGuid(out guid: TGUID): HResult; stdcall;
  external 'ole32.dll' name 'CoCreateGuid';

procedure TForm1.Button1Click(Sender: TObject);
var
  G : TGUID;
  S : string;
begin
  coCreateGuid(G);
  S := GuidToString(G);
  form1.caption := S
end;

Hi

What is interesting here is that CoCreateGUID does not seem to work on Windows 2003 Server R2 whereas CreateClassID does.

Thought you might find this interesting.
