File Attachment: 


In order to get this to work with newer versions of Delphi (Delphi 2009 and up), change all PChar parameters to PAnsiChar (simply search and replace "PChar" by PAnsiChar"). In old versions of Delphi, PChar was an alias for PAnsiChar, with newer versions, it is an alias for PWideChar, which will not work with the labjack DLL. Note that the updated unit is still compatible with old versions of Delphi.

Thank you for commenting on this issue and reminding us about it. I am currently updating the examples and they will use PAnsiChar instead. I will post again when they are updated.

The examples have been updated and use PAnsiChar/AnsiChar now.
