View 2 RepliesI know how to extract an entire page source into VB.NET, but once I do that how do I make VB.NET search the text and return a specific vlaue that is not constant?
Take this line from the page source for example:
<td id="actualPriceContent"><span id="actualPriceValue"><b class="priceLarge">$4.30</b></span>
the text is always constant but the price is not - how do I make VB.NET return the price?

I'm looking for an efficient means of extracting an html "fragment" from an html document. My first implementation of this used the Html Agility Pack. This appeared to be a reasonable way to attack this problem, until I started running the extraction on large html documents - performance was very poor for something so trivial (I'm guessing due to the amount of time it was taking to parse the entire document).[code]...
View 3 RepliesI'm reading html tags from a webpage using Webbrowser and HtmlElementCollection class. Then I invoke specific members (link, buttons etc.) depending on their attributes.I got stuck at one point. The webpage has many similar images in one place. They can be distinguished only but a version number. I need to get this number somehow to be able to invoke the correct link/image.this is the example of the html code (it looks like that - I only removed personal imformation from it) - lets say I got it already saved in a textbox:
<TR>
<TD>My text for label</TD>
<TD>my text for description</TD>
<TD>27 February 2011 12:12</TD>
[code]....
Now - I'm after the number 197 which appears couple of times in the code.I know what is the 'My text for label', 'my text for description' and 'my username'. Also those 3 links in form of images have always the same structure, apart from the number in question - number 197.How do I extract the 197 number alone ? If I would get it, I would use it to identify the link with ID: "id=snapshot_deploy_cms-company-3" and invoke it.Basically I want to do this:If a TR tag contains 'My text for label' and also contains 'my username', then read the number 197 and... say... save the number into a textbox.
I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

View 6 RepliesI have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-

Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]

I am using visual basic 2005. I found on the web the following function that extracts HTML from webpages. It is very useful but unfortunately it does not work with redirected pages. That is, when I put in it a URL of a redirect page it gives me nothing or error. I added to it ".AllowAutoRedirect = True" but still it did not work. I wonder how to make it work for redirected pages.

View 9 RepliesLet me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.
