ImageLink Demo
==============

This demo shows how to use the DBWebImage control with string columns in a
DataTable.  In DBWeb 1.0, only Blob columns could be used with DBWeb image.
In DBWeb 2.0, if a string column is found its contents are interpreted as
a link to an image file.

Before running the application for the first time, double click on the
DBWebDataSource control in the tool tray, and then use the object
inspector to set its XMLFileName property to "countries.xml" in this
directory.  You are ready to run.  The jpgs for this demo are stored
in the jpg subdirectory.

Important Note:
===============
Read-write applications using XMLFileName require that web clients have write access to the XMLFiles they are writing to.  If the web client does not have write access, a permissions error will occur whenever the client attempts to update the xml file.  To avoid this, the application developer needs to grant rights to the clients who will be using the application.  There are two ways to do this:
1.	If UseUniqueFileName is false, then all users need to have write rights to the file specified by the XMLFileName property.  To do this:
a.  In your folder options, make sure that 'Use Simple File Sharings' is NOT checked.
b.  Using Explorer, locate the XML file being used in the project.  Right click, select properties, select the Security panel, add user 'EveryOne', and apply 'Full Rights' over this file.
	If User Authentication is being used, and UseUniqueFileName is true, then the application developer will typically want to create a users group for the application, and to have the user xml files be created in a specific directory off of the Web Root directory:
a.  If you want a new User, create a New User 'MyAppUser'.
b.  In the Virtual Directory where the Web application is built, create a new folder named 'CacheFiles' (or whatever path name you desire).
c.  Using Explorer, locate the <b>new folder</b> to be used for holding the cached xml Files.  Right click, select properties, select the Security panel, add user 'MyNewUser' (or 'EveryOne' if you don't limit the users to the applicaiton), and give 'Full Rights' over this folder.'(Again, 'Use Simple File Sharings' must be unchecked').
d.  Move the base xmlFile to this folder, and then usING the Object Inspector, set the DBWebDataSource.XMLFileName to this file.
