<h1><a name=MYSAMPLE>Sample </a>User Interface Extension</h1>
<h1><span style='font-size:14.0pt;mso-bidi-font-size:24.0pt;color:red'>[This ispreliminary documentation and subject to change.]<o:p></o:p></span></h1>
<h2>SUMMARY</h2>
<p>This sample shows how to write Windows Image Acquisition (WIA) userinterface (UI) extensions. It adds tabs to the device properties dialog(accessible from Explorer) and it adds commands to the context menu for thesample camera device’s icon. These extensions are applied to the WIAsample camera from this DDK by providing implementations of IShellPropSheetExtand IContextMenu.</p>
<p>At the time of this writing, WIA is only supported on Windows ME and WindowsXP. This sample will not work on Windows 98 or Windows 2000.</p>
<h3>BUILDING THE SAMPLE</h3>
<p>To build the sample follow these steps:</p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]><span style='mso-list:Ignore'>1.<spanstyle='font:7.0pt "Times New Roman"'> </span></span><![endif]>Inthe Start menu, select<span style='mso-spacerun:yes'> </span>"FreeBuild Environment" or "Checked Build Environment" under"Windows DDK" to open a command window and set basic environmentvariables needed to build drivers. </p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]><span style='mso-list:Ignore'>2.<spanstyle='font:7.0pt "Times New Roman"'> </span></span><![endif]>Changeto the directory containing the sample driver source code,src\wdm\wia\extend.</p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]><span style='mso-list:Ignore'>3.<spanstyle='font:7.0pt "Times New Roman"'> </span></span><![endif]>Executethe "build" command. After the build completes, a library namedExtend.dll will be located in a subdirectory.</p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]><span style='mso-list:Ignore'>4.<spanstyle='font:7.0pt "Times New Roman"'> </span></span><![endif]>Alsobuild the sample camera driver located in the src\wdm\wia\wiacamdirectory.</p>
<h3>USING THE SAMPLE<o:p></o:p></h3>
<p><! ---------------- Snip Snip ---------------- >To use the driver, followthe instructions in the sample camera readme file, <ahref="../wiacam/wiacam.htm">wiacam.htm</a>.</p>
<p>To test the sample UI extensions, open the Scanners and Cameras folder inExplorer.</p>
