<h1><a name=MYSAMPLE>Sample WIA Camera Driver</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-modeminidriver for a camera. It simulates a camera by reading images from a directoryon the hard 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 part is the main minidriver.The “Fakecam” sample implements a camera microdriver that this driver calls.The third part 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\wiacam.</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 Wiacam.dll will be located in an object subdirectory.</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 microdriver in src\wdm\wia\fakecam and the userinterface extension located in the src\wdm\wia\extend directory.</p>
<h3>USING THE SAMPLE<o:p></o:p></h3>
<p><! ---------------- Snip Snip ---------------- >To use the driver, firstinstall it following these steps: </p>
<ol start=1 type=1> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>Copy Wiacam.dll from the appropriate object subdirectory under Wiacam to a new, empty directory.</li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>Do the same with Extend.dll and Fakecam.dll.</li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>Copy Wiacam.inf to the same directory.</li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>In Windows Me or Windows XP, open the “New Device” icon in the Scanners and Cameras control panel.</li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>Click the “Have Disk” button and enter the name of the folder created in step 1.</li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l2 level1 lfo5;tab-stops:list .5in'>Click OK, Next, or Finish until the wizard is finished.</li></ol>
<p>Sample camera driver reads images from <i>"image"</i> directory of the profile folder of LOCAL SERVICE account. The default location of this directoryis <i>"c:\Documents and Settings\LocalService\image"</i>, however it may be different on a particular Windows installation. You may need to enable viewing of hidden and protectedOS files in order to browse this folder (to do so, open Windows Explorer, choose <i>Tools, Folder Options, View</i>, then check <i>"Show hidden files and folders"</i>, and uncheck<i>"Hide protected operating system files"</i>).</p>
<p>Use one of these options to test this driver:</p>
