The Wonderful World of Web Applications: HTML Apps (HTA) [con't]
You can access all of the attributes of the
tag via its
In the HTA Helpomatic, select the "
item from the "
HTA Elements" list. This selection does not create
any HTML markup, but rather, produces Subroutine Code. Click the "
to Clipboard" button beside the "
Subroutine Code" textarea and
paste it within the VBScript tags of the HTA source. By default, the subroutine loads a
text file named
computers.txt from the same directory as the HTA file and loads
the contents into a
<SELECT> element named
From there, you can to tweak the code
to suit your particular needs. Here is the same routine with code to dynamically
<SELECT> element, populate it with the contents of the "
file, and append it to the document:
I also incorporated two VB best practices of including the
Explicit statement to enforce variable declaration and releasing the objects
from memory once we're done with them.
Here's the tree list to put in the
trees.txt file. Paste them
in a text editor and save the file to the same directory as the HTA file:
The above code appends the
<SELECT> element directly below
the attributes that we printed earlier:
In today's tutorial, we saw how HTAs permit web developers to
parlay their scripting and design skills to build desktop applications. Moreover, we affirmed that developers don't
need to purchase any specialized software to create them. Next time, we'll
explore some security considerations, deployment options, and develop somewhat
more abstruse tasks.
