VS 2010 Why Does WebClient.DownloadString Remove Part Of HTML's Source
Nov 13, 2011When I go to webcrawler.com and search for something, then look at the source code, a chunk of HTML similar to this displays the search results:
<div id="webResults">
<div class="searchResult webResult">
<a class="resultTitle" data-icl-coi="540" data-icl-cop="results-main" href=[website] target="_blank">[title]</a>
[code]....
But when I use WebClient.DownloadString to read the source code to a textbox, I only get this:
<div id="webResults">
</div>
There's nothing. All of the webresults have been removed.How come I can view the code in my internet browser but not on my application?? I even used an InStr method to confirm that the results weren't contained in the generated code.

WebClient.DownloadString Not Getting Whole HTML String
Nov 11, 2010I'm working on a project that scrapes data from government websites. I've noticed that whenever I use WebClient it doesn't always get the whole HTML code. Even when I get the robots.txt file it doesn't return everything. For example, http://www.bbc.co.uk/robots.txt has 80 lines but I'm only getting 13 lines.
If an HTML block uses "display: none" in the style I can't get anything between the hidden HTML blocks.Here is the sample code I'm using:[code]...

VS 2010 - Speed: WebClient Versus Socket
Apr 25, 2012I make a lot of programs that require an internet connection to download things from the web.At the very beginning, I used WebClient, as I didn't know Socket & how it worked.But now, I use Socket all the time, altough it's more lines of code. It seems to work faster then WebClient.I am interested if this is really true & why WebClient is slower (so is HttpWebRequest) then just a Socket.I've setup 2 threads which starts on the click of a button (WebClient thread starts first), the Socket beats the WebClient by just some milliseconds, but still.Each way has it's advantages & disadvantages, e.g.: if you use Socket, you need to write the header yourself & parse the response header.My question is, which one do you prefer & why ?Do you know why WebClient & HttpWebRequest are slower then Socket, as I assume, WebClient & HttpWebRequest both use tcp to download the things.

View 11 RepliesVS 2010 - ProgressBar Added And Set To Continuous Style
Jun 20, 2012I have an application that has a ProgressBar added to it set to Continuous style. Everything seems to work great except that the progress bars seems to "fill in" slower than needed. As a test, I created a form with a continuous progressbar and a button. The button code only sets the progressbar's value to 100 (which is the max). Basically, for the test, the value changes from 0 to 100, but the ProgressBar seems to incrementally fill in like it is doing a PerformStep or something. I don't get it. Is there a way to get the ProgessBar to go from empty to immediately full when setting the value from 0 to 100 without the animated filling?

View 5 RepliesVS 2010 Wait On Repaint Before Exit - Progressbar?
Jan 6, 2012I'm having issues with a progressbar. I've created a progressbar that reads registry variables and uses that input to update the progressbar and some status messages (so I can call it from vbscripts, etc). I want it so when my status bar hits 100%, the bar stops, waits a few seconds, and then quits. However, it seems the program processes the remaining code and quits the application before it has time to completely repaint the progress bar (I'm guessing this because it will usually update to about 10% before it exits).. I'm using something like this...
If prcnt = 100 Then
progbar.Style = ProgressBarStyle.Blocks
progbar.Value = 0
