Hi,
I kept getting an exception error when running the example. It turns out that "MidasLib" is needed in the uses statement of this example code:  http://www.festra.com/eng/db03.htm

On my computer with Delphi Community edition, I get no errors without MidasLib in the uses. Which version of Delphi are you using?

I compiled the code of the tutorial part 3. It runs fine on my PC. But when I copied the resulting exe and the xml-file to a folder of another PC, it doesn't work.
I did some searching with Google and it seems that this has something to do with midas.dll or midaslib. There is no mention of "midas" in your code examples, maybe that is the reason of the errors?

The program works on the first PC, because that PC contains MIDAS.DLL

Your second PC probably doesn't have Delphi installed and therefore it doesn't contain MIDAS.DLL
Mea culpa, we forgot to mention that an additional step is needed if you want to deploy the application on another PC without Delphi.
There is a work around for this: we make sure that the MIDAS stuff is compiled into the EXE of the application. This can be done by modifying the "uses" clause in the DPR file of the project as follows (add Midaslib to the "uses"):

program UFOdata;

uses
  Vcl.Forms, Unit1 in 'Unit1.pas' {Form1}, Vcl.Themes, Vcl.Styles,
  Midaslib;
