<h1><a name=MYSAMPLE>Sample WIA Camera Microdriver</a></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 a Windows Image Acquisition (WIA) user-mode microdriverfor a camera. It simulates a camera by reading images from a directory on thehard disk. This sample driver can be used as a starting point for yourdevelopment, but your driver should access the camera hardware through one ofthe kernel drivers provided with Windows.</p>
<p>This sample is implemented in 3 parts. This is part is the microdriver. The“Wiacam” sample implements the WIA minidriver that calls this driver. The thirdpart is the sample UI extension “Extend.”</p>
<p>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]>1.<span style='font:7.0pt "Times New Roman"'> </span><![endif]>In the Start menu, select<span style="mso-spacerun:yes"> </span>"Free Build Environment" or "Checked BuildEnvironment" under "Windows DDK" to open a command window andset basic environment variables needed to build drivers. </p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]>2.<span style='font:7.0pt "Times New Roman"'> </span><![endif]>Change to the directory containing the sample driver sourcecode, src\wdm\wia\microcam.</p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]>3.<span style='font:7.0pt "Times New Roman"'> </span><![endif]>Execute the "build" command. After the buildcompletes, a driver named Fakecam.dll will be located in an objectsubdirectory.</p>
<p style='margin-left:.5in;text-indent:-.25in;mso-list:l0 level1 lfo2;tab-stops:list .5in'><![if !supportLists]>4.<span style='font:7.0pt "Times New Roman"'> </span><![endif]>Also build the minidriver in src\wdm\wia\wiacam and the userinterface extension located in the src\wdm\wia\extend directory.</p>
<h3>USING THE SAMPLE<o:p></o:p></h3>
