I know have a second very strange problem: I have two .bpr projects for the
same code except that one is for debugging with a dummy form and the other
one is a service. The object creation/destruction orders are the same.
However, when I run the ISAPI code (even once) as below, the service gives
an AV and the "Please tell M$ about this" screen appears. This does not
happen in the form project!
Your constructive response will be appreciated!
Best Regards,
SubZ

Do you still have message box in the code ? This may cause the problem
because it call the message
pump and wsocket_send may be called from elsewhere. Never use MessageBox to
show values, use
Windows.OutputDebugString or use Writeln (don't forget to make your app a
console mode app).
Maybe I found the problem. WSocket_send is defined as:
function WSocket_send(s: TSocket; var Buf; len, flags: Integer): Integer;
This means you have t call it like this:
Count := WSocket_send(HSocket, Data^, DataLen, 0);
See the "^" that I added. Since the Buf argument is declare as untype var,
the compiler
automatically take the address. So when you pas "Data", then it is the
pointer address that is
passed. When you pass "Data^", the actual pointer value is passed.
