<h2>SUMMARY</h2>
|
|
|
|
<p>This sample shows how to write Windows Image Acquisition (WIA) user
|
|
interface (UI) extensions. It adds tabs to the device properties dialog
|
|
(accessible from Explorer) and it adds commands to the context menu for the
|
|
sample camera device’s icon. These extensions are applied to the WIA
|
|
sample camera from this DDK by providing implementations of IShellPropSheetExt
|
|
and IContextMenu.</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]><span style='mso-list:Ignore'>1.<span
|
|
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>In
|
|
the Start menu, select<span style='mso-spacerun:yes'> </span>"Free
|
|
Build Environment" or "Checked Build Environment" under
|
|
"Windows DDK" to open a command window and set 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]><span style='mso-list:Ignore'>2.<span
|
|
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Change
|
|
to 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.<span
|
|
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Execute
|
|
the "build" command. After the build completes, a library named
|
|
Extend.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.<span
|
|
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Also
|
|
build the sample camera driver located in the src\wdm\wia\wiacam
|
|
directory.</p>
|
|
|
|
<h3>USING THE SAMPLE<o:p></o:p></h3>
|
|
|
|
<p><! ---------------- Snip Snip ---------------- >To use the driver, follow
|
|
the instructions in the sample camera readme file, <a
|
|
href="../wiacam/wiacam.htm">wiacam.htm</a>.</p>
|
|
|
|
<p>To test the sample UI extensions, open the Scanners and Cameras folder in
|
|
Explorer.</p>
