John,
It still doesnot work ..
I am created the PDB using PDB converter. Is it causing problem
because of the format ? I am able to get the first field of the
structure. But not others ??
Do you have sample program for reading db records field wise .. ??
Pls let me know how to go about this ..
Thx,
Andy
