<i>2 freeware utilities including MFC source code to quickly change Screen Depth and
Resolution</i></font></h2>
<p><font face="Arial" size="3">Tired of using the Windows Control panel or QuickRes to
change your graphics cards screen depth & resolution. This program uses the command
line sent to it to change the screen depth & resolution. For example to change into
1024 * 768 in 24 bit colour, just use the command line "ResSwitch.exe 1024 768 24
0". With this structure you can create a number of shortcuts to ResSwitch on your
desktop using different command lines which will allow you to change mode with a simple
double click on your desktop. By setting up shortcut keys in the shortcut file to
ResSwitch you can quickly change modes by just using the keyboard only. The size of the
binary file itself is only 6K. </font></p>
<p><font face="Arial" size="3">Also included is ResList which is a simple console app
which lists the available video modes which ResSwitch can use.</font></p>
<p><font face="Arial" size="3">The </font><font face="Arial"><a
href="http://localhost/download/qres.zip">enclosed zip file</a> contains </font><font
face="Arial" size="3">the ResSwitch and ResList source code, a very handy MFC class to
wrap access to the two underlying API's ResSwitch and ResList uses and a prebuilt binary
version of both programs. The enclosed binary requires that you have the MFC 4.2b DLLs
already installed. If you haven磘 already got them on your machine (MFC42.DLL in your
Windows system directory), then grab them from Microsoft磗 web site at <a

<ul>
<li><font color="#000000" size="3" face="Arial">To use the class in your code simply include
videomod.cpp in your project and #include videomod.h in which ever of your modules needs
to make calls to the class.</font></li>
<li><font face="Arial">Your code will need to include MFC either statically or dynamically.</font></li>
<li><font face="Arial">You will also need to have afxtempl.h in your precompiled header.</font></li>
<li><font face="Arial">To see the class in action, have a look at the code in the main
function in the module "ResList.cpp" or the Winmain function in the module
"ResSwitch.cpp".</font></li>

<p><strong><font face="Arial">v1.1 (25 September 1997</font>)</strong>
<ul>
<li><font face="Arial">Changed name "QuickerRes" to "QRes" to avoid
conflict with an similarly named third party product. </font></li>
<li><font face="Arial">Now supports setting the monitor frequency (NT only according to the
documentation).</font> </li>
<li><font face="Arial">Inclusion of a new console mode program called QList (binary &
source code) with enumerates all the video modes available. Comes in helpful if QRes is
reporting that some options you select is unavailable.</font> </li>
</ul>
<p><strong><font face="Arial">v1.2 (4 January 1999</font>)</strong>
<ul>
<li><font face="Arial">Changed name (yet again) from "QRes" to
"ResSwitch" to avoid conflict with another similarly named third party product. </font></li>
<li><font face="Arial">Source code now ships with Visual C++ 5 workspace files now as
standard.</font></li>
<li><font face="Arial">All source code is now fully UNICODE enabled and UNICODE build
configurations are now provided.</font></li>
<li><font face="Arial">General tidy up of the codebase.</font></li>

display device in a particular mode. On some early builds of Windows 95, changing the
frequency of the display adapter is not supported and this value should be set to 0 which
means the default hardware value.</font></p>
