   2. Form as Object, and Persistent form (TBD)

For beginner(White Belt)

1. Write C++ CGI Version of "Hello,World"
   

   Source:	hello.cpp (Need compile)
   Sample:	hello

   First sample shows the most primitive case of CGI by C++. This doesn't use jj/CGI, but I think it is good introduction for it.

   That is, "Hello,World" by CGI/C++;-)

   I know this CGI doesn't have any advantage than static HTML text. This is just first example...

2. Basic handling of CGI Form
   

   Source:	put_a.cpp (Need compile)
   Sample:	put_a.html

   put_a puts the value of text field named 'a'.

   put_a.cpp shows that creation of form object typed jjCGI_form, parse CGI input data, and get the value of field 'a' by form["a"].

For Middle class(Green Belt)

1. How to scan values of all fields in CGI form
   

   Source:	put_all.cpp (Need compile)
   Sample:	put_all.html

   This sample shows how to scan all of values in the form.

   put_all.cpp shows how to use jj/Pattern library which is a base of jj/CGI.

2. Handle Multiple-value Field
   

   Source:	multi_value.cpp (Need compile)
   Sample:	multi_value.html

3. How to handle file uploading
   

   Source:	fupload.cpp (Need compile)
   Sample:	fupload.html

   In jj/CGI, uploaded file is accessed by user's CGI program through temporary filename saved at server as follows:

   form._server_filename[field_name]

   Where, form is an object of jjCGI_form class, field_name is a name comes from HTML form like:

   <input type="file" name="field_name">

   Usually, _server_filename[] member is enough to handle uploaded file. The other attributes related to file-uploading are as follows:

   _client_filename[]	Client side file name
   _ctype[]	type of file

For Master class(Black Belt)

1. How to handle Cookie
   (TBD)
2. Form as Object, and Persistent form
   (TBD)
