We are just starting to develop for the Internet, our project is an ISAPI DLL, and we are using Windows NT Personal Web Server.  We are trying to figure out how we can debug the DLL within Delphi 5.  We found some instructions for Windows "95" personal web server, but we can seem to figure out NT.  Any help would be greatly appreciated.

Use 'c:\winnt\system32\inetsrv\inetinfo.exe' as host application and '-e w3svc' as parameter

Do a *find* in the Delphi help and search for 'debug isapi'

take a look at this

There are serveral things that you will learn quickly about debuging ASPI.  If you have a more specific question we can narrow it down for you but as you know this question is about as vague as "how do I do user administration with NT"

also do key word searches at

good luck

Bob Swart (a.k.a. Dr. Bob), has written an application that lets you debug ISAPI DLLs written with Delphi. It's integrated to the Delphi IDE, and quite handy. I found it to be much easier to use than PWS or IIS.

Here's the URL:

It's a great tool and, best of all, it's free!

Another thing that should be noted is that the personal server makes it kinda easy to start and stop the web secvices...under IIS this is a bit harder.  Basically for performance reasons the DLL is only loaded once and then multisessioned.  This means that only one memory instance of the DLL is running.  You will see a problem here if the thing errors out because you have to stop the service to overwrite the IASPI with your newly compiled code.  Look at this page for some help
