I AM SORRY FOR SEND THIS AGIN BUT THE FIRST TIME I FORGOT THE SOURCE CODE
AT THE END OF THE EMAIL
Here is the list good luck.
1) I need to save information from my java applet to a flat file on my
site.
I need to find out how to read the file and write to the file on my
web site from a applet.
2) Can someone show me a sample on how to use java as a cgi program.
How can a form pass it data?
How can a java applet pass it data?
How can the java cgi program read the data in?
3) In following source code I have a listbox I let the user pick a
item from. Can someone please show me how to turn my listbox into
option buttons. Also How did I tell which button is selected?
I am new to java as you can see. But I did read about 3 books on java
none of the books got me to the point of writing a applet to let the
user read and writer information from my site and about AWT.
Can this be done????
I need to get something up by the end of the week so any help will be
alot of help. So please send me any sample you how??
Once again thanks to all you great java programmers on the net.
