Codes for using MathLink with GUI dialog boxes (New versions)

Dear MathGroup,

I am pleased to announce new and improved versions of my MathLink 
programs for connecting to GUI dialog boxes.

Here are bits of the first announcement for the benefit of new
MathGroupies and others:

The new version, inputbox2.0, is much cleaner codewise with quite a
lot of explanatory comments. The code now implements a second dialog
box, designed for multiple-choice questions where the user response
is simply one of "A", "B", "C", "D" or "Don't Know" (these labels
may be easily changed by editing the program resources).

Once more, your feedback and suggestions are welcomed. The code is
available at URL
 <gopher://othello.ma.ic.ac.uk/11/project/DialogBox/inputbox2.0/>
or (for the old-fashioned) by gopher and anonymous ftp to
 othello.ma.ic.ac.uk (IP 155.198.192.26)
in directory
 project/DialogBox/inputbox2.0

To try out the program, download the appropriate version of inputbox.exe
and then in Mathematica do something like:

 link=Install["inputbox.exe"] (*You may need to SetDirectory[] first*)
 string1=TMPInputBox["Question text"] (*The string-input dialog*)
 string2=TMPMCQBox["More question text"] (*The multiple-choice dialog*)
 Uninstall[link] (*when finished, or quit the kernel*)

Regards, Phillip Kent.
