1. try run this code on device
2. may be server not worked your packet?
vk> hi all,
vk> i am trying to get data from a the specified URL on PalmOS Simulator5.1 ,
using the NetMgr.h
vk> i have written this code : all functions run successfully and return no
error ..but i am unable to receive data.
vk> // Find the network library
vk> error=SysLibFind("Net.lib", &AppNetRefnum); // returns 0 if no error
vk> if (error==0)
vk> { FldInsert(fldptr1, "could find Net.lib ", 19); }

vk> { FldInsert(fldptr1, "could not find Net.lib", 22); }
vk> // Open the network library
vk> error = NetLibOpen(AppNetRefnum, &ifErrs);
vk> if(error==0)
vk> { FldInsert(fldptr1, "could open Net.lib ", 19); }
vk> else

vk> all those who are working on internet application using NetMgr.h kindly
help...i am unable to find my fault..but there is one for sure..suggestions are
welcomed.
