I get an error on da line objPost.Close() ;.....the unusual error is that when I debug this code line by line slowly using F10 in visual studio 2010...the code works..but when I just run the program or even debug the program fast...it throws an error at that line.. it gives an error that the connection which was expected to be open was closed by the server..

HELLLLPPP!!!
