Hi!
I try to develop a Web Application in Delphi 6 and want to debug it using WebAppDebugger. I've done this before on another machine (Win XP Pro) but just could not get it work in my home machine (Win98, Win ME). When i start WebAppDebugger, press Start button and click on the label to show me the ServerInfo page i receive a page with 3 lines:
Internal Server Error
HTTP status code: 500
HTTP error message: Interface not supported

Does anyone knows something about this problem and how may i fix it?

thank you in advance

hi,
PWS on Windows 95/98
1. Open your project.
2. Set the following the in the Run Parameters:
Run: \inetinfo.exe
Parameters: -e w3svc
3. Now, set your breakpoints and click on Run. Make sure that
your dll is located in the scripts directory.
4. Call the dll from your browser.

Hi Imbeginner.

Unfortunately I couldn't understand your comment.
1) There's no "Run" parameter in the Run->Parameters - there's "host application". Did you mean this? /i'm using Delphi 6/
2) Which is scripts directory?

please explain more. thank you.

1) that s right
you must find the location of inetinfo.exe
and set on host-application section

2)which directory of your web service in your computer has permissions for executing dll,cgi

I see... If i understand right - you suppose that i have (or must have) some Web Server (like Appache for Win or any other) installed on my PC. Am I right?

But i don't have any web service on my computer. As i've read & did it before - there's no need to have any web service (web server application i mean) to test Web Server Delphi applications. You may use Web AppDebugger instead. The problem is that for some reason it doesn't shows the information i used to see - i mean - when you start WebAppDebugger (from Tools menu), clisck start button & then click on the label for ServerInfo - it shows a page containing information about registered applications (like a combobox) so you can select one and start it or see some info about it. But unfortunately on my computer WebAppDebugger doesn't show this page :-(

So - i need some information about this problem. If (on the other hand) you recommend me to use some Web Server - ok, i'll try this way too. But which Web Server you have used & like most?

Just after i've sent the previous comment i understood that PWS means Personal Web Server. So now i'm trying to download it from Microsoft & will see what will happen when install it.

hi,  
From troubleshooting of webdebugger

Symptom

Internal error 500. Interface not supported.

Solution

Register the weblib.tlb typelib using tregsvr (i.e., tregsvr weblib.tlb).

-----------------------------
every tregsrv.exe and weblib.tlb existed in delphi/bin directory
