Access violation in ntdll.dll - when running as isapi.dll

[alfr]

Hi, 

 

I use a 3rd part tool from TMS Software - called Flexcel for creating excel files. It in general works well.

 

However a part of it is also for creating a pdf-file out of the excel-file. This works well as long as I run the application as an exe-file on my development pc, but when instead run it as an dll on iis, I get an access violation in ntdll.dll.

 

Anybody having any clue what might causing this kind of exception in IIS/ntdll.dll but not as an exe? 

 

Access violation at address 77EADE33 in module 'ntdll.dll'. Write of address 00000014

You can use EurekaLog or such app for finding place of an issue.

Found the solution - so post it here as well if somebody else is getting the same problem.... A special init is necessary if calling the 3rd part from a dll. Simplest is just to call the DllInit before using it and DllShutDown whe done. 

 

procedure CreateReport;

begin

   FlexCelDllInit;

   try

      //Code that uses FlexCel

   finally

      FlexCelDllShutDown;

   end;

end;
