say instance need extract out text between these span tags how go that, receiving error stating "the object reference not set instance of object" here html

there html code prior portion here; don't know if should make difference.

<div class="thumbnail-details"> <ul>     <li> … </li>     <li class="product-title">         <span class="thumbnail-details-grey">the blaster portable wireless speaker in black</span>     </li>     <li> … </li> </ul> </div>

so far c# code 

    htmlweb hw = new htmlweb();         htmlagilitypack.htmldocument htmldoc = hw.load(@"http://www.karmaloop.com/browse.htm#pgroup=1");         if (htmldoc.documentnode != null)         {             foreach (htmlnode text in htmldoc.documentnode.selectnodes("//span[@class='thumbnail-details-grey']/text()"))             {                 console.writeline(text.innertext);             }

can here, want extract out "the blaster portable wireless speaker in black". helpful, in advance.

your code works fine, you'll have load right page work. page loading uses ajax request load results see in browser.

so instead of url using have use:

htmldocument htmldoc = hw.load(@"http://www.karmaloop.com/browse?pgroup=1&ajax=true&version=2");

then code works. i'm still looking place request gets put together...

but query looks rather easy guess. example page http://www.karmaloop.com/browse.htm#pdept=11&pagesize=30&pgroup=1 request url http://www.karmaloop.com/browse?pdept=11&pagesize=30&pgroup=1&ajax=true&version=2. have use url , build new 1 starting after #.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
