This on a call to Xero.

I am upgrading from ActiveX to DLL's. I am using Delphi 2010 which may not be recommended for the DLL product but everything else is working, i.e. HTTP, Request and Response.

As soon as I introduce the RSA calls the first calls works and 2nd and subsequent fail with a 500 server error. If anyone can confirm that this is just a Delphi 2010 problem I will put the upgrade on hold until 2016. This is the event log for the failing call...

I have put it down to using the DLL's in Delphi 2010. Not a good idea. I swapped to the ActiveX component and it all works beautifully :-)

Thanks! Yes, the DLL is only valid for Delphi XE2 and greater..
