DLL in Delphi6 problem

[Chris Keating (iAnywhere Solutions)]

I suspect that the Delphi PCHAR arguments should be PowerBuilder REF STRING.
You should also preallocate memory using SPACE( ) if the values are
populated in the DLL.

Can you elaborate on this and maybe offer some evidence. Your general
statement does not sound correct.

Did you use any thread class or maybe you created another thread in some
other way ?
If so - be sure if all the threads are closed - PB doesn't works properly
with threads :(
