Re: CGI-RPG Parameters with different sizes

["Brad Stone" <brad@xxxxxxxxxxxx>]

Peter,

you can't rely on the data being of a certain size when read
from a web page.  You can control it's Max size, but that's
about it.

You really should be using 1 of 2 options.

1.  Read the data in (QtmhGetEnv or QtmhRdStin, depending if
it's a GET or POST).  Then, use QtmhCvtDB to convert the
data into a usable format.
2.  Use the QzhbCGIParse API to read in each variable at a
time.  (my preferred method).

#1 is cumbersome and yucky.  #2 is as easy as pie.  My first
e-RPG book explains #1, and my 2nd will also include #2
(hopefully out in 3 or so months).

In the meantime, I do have some wrappers that may help on my
webpage at:
http://www.bvstools.com/download.html

The "2nd set of HTTP Procedures" contains a wrapper for the
QzhbCGIParse API that you can use like this:

eval Myfield = #CGIParse('-value myField')

VERY easy to use.
