Also, I read the Sample code from INetLow and I could extract the
information I needed. The stucture is too different. Does this sort of
operation require all that complex code? I'm hoping that code was just
to support asynchronous transmission. I don't care about that - not for
now anyway.
I just want to be able to talk to an asp program on our webservers. I
want to send (plaintext) information or requests for (plaintext)
information from the palm to the servers and update the data on the palm
with the responses. Are there any serious holes in this plan?

Subject: Still on the INetLib
This is driving me very insane. I seem to not be correctly initializing
the sockHP. When I run it, I get errors that the lines with sockHP in
it a about trying to access the address that sockHP holds (from the
debugger).
This function is SUPPOSED to take a URL from txtRequest field and put
the txtResponse field. Just that simple. No asynchornous nothing.
This should be simple. Maybe I'm missing a step. Maybe the sockH
should be preallocated with as a NewMemHandle? If that's the answer, I
can't figure that out either.
I did order a bunch of books to compliment the online docs from my boss.
(So I'm not just trying to freeload off here)
Please?
Thanks,
Jason
