<h1>InstallOptions 2</h1>
<div>
<h2>Introduction</h2>
<p>InstallOptions is a NSIS plugin which allows you to create custom pages for NSIS installers, to
prompt the user for extra information.</p>
<p>InstallOptions will create a dialog which will be displayed inside the NSIS window. The controls
on the dialog can be defined in an INI file.</p>
<p>NSIS 2 has a new page system, which allows you to add custom pages to your installer without
messing with Prev/Next functions. With the new plugin system, you also don't have to worry anymore
about extracting and deleting the DLL file. When you store the INI files in the plugins directory,
NSIS will also delete them automatically.</p>
<p>This new version of InstallOptions has been designed for NSIS 2. It supports customized user
interfaces and custom font and DPI settings.</p>

<h1>VPatch 2</h1>
<div>
<h2>Introduction</h2>
<div>
<p>VPatch allows to create a patch file to update previous versions
of your software. The GenPat utitily generates the patch file. The
plug-in can use the patch to update a file. Using a patch, you can
reduce the download size of your updates, because only the differences
between the files are included in the patch file.</p>
</div>
<h2>How to use</h2>
<div>
<h3>Generate the patch file</h3>
<div>
<p>Make sure you have the source file (original version) and the target
file (version to update to). For example, DATA.DTA (currently on user
system) and DATA_20.DTA (version 2.0 of this data file). Now call

after the filenames), you can use a different block size. A smaller
block size may result in a smaller patch, but the generation will
take more time (the default blocksize is 64).</p>
</div>
<h3>Update the file during installation</h3>
<div>
<p>Use the VPatch plug-in to update a file using a patch file:</p>
<pre>

<li>No suitable patches were found</li>
</ul>
<p>Check <a href="example.nsi">example.nsi</a> for an example.</p>
</div>
<h3>Multiple patches in one file</h3>
<div>
<p>GenPat appends a patch to the file you specified. If there is already
a patch for the same orginal file in the patch file, the patch will
be replaced. For example, if you want to be able to upgrade version

from file B version 1 to file B version 2. Just call the plug-in multiple
times with the same patch file. It will automatically select the right
patch (based on the file CRC).</p>
</div>
<h3>GenPat exit codes</h3>
<div>
<p>In version 2.1 support was added for exit codes (known as error levels
in the DOS period) to GenPat. GenPat will return an exit code based
on succes of the patch generation. Here is a list of the possible

a script.</p>
</div>
</div>
</div>
<div>
<h2>Source code</h2>
<div>
<h3>NSIS plug-in (C++)</h3>
<div>
<p>The source of the NSIS plug-in that applies patches can be found
in the Source\Plugin folder.</p>
</div>
<h3>Patch Generator (Delphi)</h3>
<div>
<p>The most interesting part of VPatch, the actual patch generation
algoritm, can be found in Source\GenPat\PatchGenerator.pas. The header
of that file contains a brief explanation of the algoritm as well.</p>
</div>
<h3>User interface (Delphi)</h3>
<div>
<p>A user interface is included as well, which you will have to build
yourself because the GUI executable was too large to include. Besides
Borland Delphi 6 or higher (you can use the freely available Personal
edition), you will also need to install the <a href=
"http://www.delphi-gems.com">VirtualTreeView</a> component by Mike Lischke.</p>
