Thank you shru_0409: for the reply.
but i want to do it through API calls, as mscript is giving me problems in some machines, especially in server 2000 and server 2003. and rarely even in some xp machines too.

so i am forced to go for pure api calls.
please find the sample code given in my previous reply. it is written in pb 10.5
and is working fine.

in pb10      Asc(String(lblb_data, EncodingAnsi!))  may return a value greater than 256
but in pb7  Asc(String(lblb_data!)) always return <256

i think this is the actual problem.
can any one help me?
