Hi All,

I have an ISAPI dll (using TWebModule) and I need to know where I can put the code for when the DLL is UNloaded from IIS.

I can find the following ok:
thread create (TwebModule.onCreate)
thread destroy (TwebModule.onDestroy)
process create (see below - run when loaded in to IIS)

library dart;
uses
  fastsharemem,
  ActiveX,
  ComObj,
  WebBroker,
  ISAPIApp,
  ISAPIThreadPool,
  Classes;
{$R *.RES}
exports
  GetExtensionVersion,
  HttpExtensionProc,
  TerminateExtension;
begin
  myInitRoutine; // THIS IS RUN WHEN ISAPI IS LOADED IN TO IIS
  CoInitFlags := COINIT_MULTITHREADED;
  Application.Initialize;
  Application.CreateForm(TDARTModule, DARTModule);
  Application.Run;
  // can NOT run myKillRoutine here!
end.

I am wondering where I can put the code to run when the ISAPI dll is UNloaded from IIS (e.g. restart IIS).  This is different from when a thread (request or action) is finished...

Cheers,
Peter

Add a unit to your project and use its finalization part. Alternatively look at the documentation about DllProc.
