V8 of dll produces error when freed

[sitestepper]

I just started integrating HtmlValidator into my Sitestepper web maintenance program.

I am using Delphi 7 and decided to write a wrapper class around the dynamically loaded dll.

Code: Select all

   hvi := TStepHVI.Create;
   try
      if hvi.DllAvailable
      then
         lbl1.Caption := 'Html-Validator is OK'
      else
         lbl1.Caption := 'Html-Validator CANNOT be loaded';

   finally
      FreeAndNil(hvi);
   end;


Where the dll is loaded in the .Create call. Very simple at the moment, just trying to load and free the dll.
If I use csevalidatorv70.dll, the program runs just fine.
If I use csevalidatorv80.dll the program throws an exception somewhere in the middle of nowhere (not in my code).
If I load one of my Sitestepper dll the code runs fine also.

Any ideas ?

I will upload a zipped Delphi project in about an hour to www.sitestepper.com/downloads/sitestepperhvi.zip (4Kb).
Even if you do not have Delphi installed, look at the cStepHVI.pas file. You will see that I do not do anything special at the moment.

Thanks.

Sorry, I'm not sure what could be wrong. I do have BDS 2006, so would it be possible for you to send me a small BDS 2006 Delphi project that I could try to reproduce this in? You can send it to support at htmlvalidator dot com. This could be related to the Firefox extension not working (crashing), which I haven't look into yet but definitely plan to.

Albert, the complete project can be downloaded from the link in my post. It is a complete zipped delphi project - no password on the zip.

I am just trying to load the dll , displaying a message if it succeeds, and than freeing the dll (in preparation for a Delphi class which encapsulates the interface to your software).

Sorry, it looks like I missed that! I'll take a look and see if I can find anything.

UPDATE: I have managed to reproduce the problem with the v8.0 DLL but not the v7.0 DLL. I'm searching for a cause and solution and will let you know when I've figured it out.

This problem should now be fixed in CSE HTML Validator Professional v8.0 BETA 1C.

I can confirm that the error does not occur anymore when using the new beta version 8.0 1c.

Thanks ... I am now continuing my Delphi integration with version 8 ...
