However the socket printed something with a first line like:

No idea why. But did you use the debugger to verify that Data and DataLen
have correct values ?
To debug further, you can add an Windows.OutputDebugString in
WSocket_Synchronized_send function to display what is really sent by the

Re: [twsocket] Fw: Sync THttpConnection derivative
Debugger, just like the MessageBox showed correct values!
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.

But the error does not happen when debugging. It only occurs in service mode which is not debuggable. That's the whole problem! You can debug services ! Compile your service, run it as a service.
