Remove the typecast PansiChar()
Michael.
>> Hello Michael and thanks for answer.
But if i remove PansiChar(), i still get :
An unhandled exception occurred at $0000000000000000:
EAccessViolation: Access violation
$0000000000000000
What is the value of Pointer(soundtouch_createInstance) after the above
statement ? Is it nil ?
Michael.
