Re: CGI-RPG Parameters with different sizes

I had a question about the QzhbCGIParse, and I do know that everyone's
tastes and preferences vary,
but I was just curious, you stated that you thought the use of the CGIParse
api was easier than the CvtDB api.
I'm curious on how loading all your variables with the values from the
QUERYSTRING, or whatever, the not easier than having to retreive each
variable's value, one at a time.

Perhaps I'm merely missing something.
Just curious,
dav

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.
