Dear Jan,
Thank you very much. I checked your notes. Unfortanely
making strings Pascal Strings and changing
InsertMediaIntoTrack paramters did not fix the
problem. I did not know anything about Pascal strings
and QT usage. So, I attached my file to this mail.
Could you please take a look at the attched file and
let me know your opinion?
Additionally, making your changes did not change the
program bihaviour and unfortunately it still returns
-2050 Error.
Your help would be very much appreciated.
Regards,
* Roozbeh
