<h1>Page Mode Support</h1>

Since version 1.04, the ExperienceUI supports page modes. This term may be new to you, but it's XPUI-jargon for using identical
pages in both the installer and the uninstaller. The Modern UI also supports this, but it is very difficult to use. The
ExperienceUI allows you to insert any page you want into just the installer, just the uninstaller, or both. How does it work?
When you insert an XPUI_PAGEMODE macro, three defines are assigned values: XPUI_UN, XPUI_UNFUNC, and XPUI_UNINST. In the
Install page mode, these three are blank values. In the Uninstall page mode, however, they are assigned the values "UN", "un.",
and "UNINST", respectively. Then, to add a page to the uninstaller, all I have to do is:<br>
<br>
<code>PageEx ${XPUI_UNFUNC}components<br>
...<br>
PageExEnd</code><br>
<br>
Of course, there is also the little detail about strings. You don't want the uninstaller to confuse you by saying something
about installing the program, so I also used this technique with the strings. The language files have string tables
for all 21 pages (10 installer, 11 uninstaller, including the NSIS uninstConfirm page) and the language strings have the
${XPUI_UN} symbol in them. This allows for completely different install/uninstall strings. The code is basically like this:<br>
<code>
!insertmacro XPUI_HEADER_TEXT "$(XPUI_${XPUI_UN}COMPONENTSPAGE_TITLE)" "$(XPUI_${XPUI_UN}COMPONENTSPAGE_SUBTITLE)"
</code>

<h1>Using Page Modes</h1>
<p style=margin-left:0.2in>
<font face=Verdana style=font-size:8pt color=#000000>
Using the page mode system is very simple. Simply insert the page-mode macro and then your pages. An example of this can be
found in the Setup.NSI file in the XPUI installation directory. For more information, please see the <a href=page_macros.htm>Page Macros</a> section of
this document.<br>
<br>
If you created your scripts for XPUI versions 1.03 or earlier, you may have to change them for versions >1.04.
