VS 2010 Extracting Specific Text From A String Is Slow?

Feb 23, 2012

I have a text file I'm trying to pull specific data from to make a report in excel and am wanting to know if my code can be improved or if I have something wrong. If it's apparent to anyone that I should be doing something elThis code does work but, very slow. These reports take up to 20 minutes for about 100 files so I am wanting to decrease the time somehow. I have attached the whole sub in a text file, it's about 900 lines long so don't think I should post all of it. This is one part that seems to take the longest:Partial code that reads the text into a string, then each line is read to find whether it holds the data or not. Inside this while loop, I am checking numerous lines to see what they hold and extract specific items. First I verify it's a interface by checking for "line protocol".

Dim str As StreamReader = File.OpenText(filefound)
While (str.Peek <> -1)
If txtLine.Contains("line protocol") = True Then 'Found an interface,

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.

What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.

Here is the source that I am getting using Firefox's Firebug to inspect the element:

<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

[Code]...

Why would the two be showing me two different versions of the HTML?

And how would you be able to grab that source to view in a picturebox using webclient?

VS 2010 : Search For Strings Within Large Text Blocks (e.g. HTML Source)?

The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.

Forms :: Find Specific Text From Html Files?

Dec 23, 2010

so I had an idea today while modding a game I play. I decided to make a mod-manager.In order to start the game with mods, you have to go to the website, log in, click playnow and view the source of the html file. From there you get the sessionID variable and add it to a shortcut on your desktop. I wanted to be able to automate this process by doing the following:

on button1.click: somehow parse the source of the html file to locate the line that looks like chis:
var sessionId = 'random26charSessionID'; and take what is inside of the ' ' and add it to textbox1.text

Any ideas? Not sure if it will be in the same line every time with add banners and stuff...so I wanted to parse the doccument.

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

I am trying save a value from an input tag in some HTML source code. The tag looks like so:

<input name="user_status" value="3" />

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.

Extracting Information From HTML?

Oct 2, 2009

The method I'm currently using to extract html and the parse is via a WebBrowser control.I'm grabbing a collection of tags, sorting through the ones I want, and then pulling the innertext.Doing this on my development machine is kind of slow, but manageable. At max, I can go through 60 different web pages across 3 different sites. It takes about 5 mins on my machine.

However, this app is targeted towards machine that have a quarter of the technology that my computer has. So, it takes anywhere from 10-15 minutes. This is less than ideal.I've bee reading up on the documentation on HTTPWebRequest. However, form what I've seen I can't seem to find a way to grab the HTML and then parse it with a method from HTTPWebRequest.

Due to the way I'll be using it, I won't be able to use RegEx to parse the data and was hoping there was a method within the HTTPWebRequest property to do it.

VS 2010 - Extracting Text - Convert The English Text Shown In Screen To Malayalam

Sep 6, 2010

I'm trying to create a small program, which I think will be helpful to others(in here). My aim is to convert the English text shown in screen to Malayalam. English-to-Malayalam conversion is not a problem. But the problem is, how to extract the text from the screen. In most of the converter/translator, the text needs to be copied or written down in the translator tool. But my program will cut off that part. That is, simply move the program window (having a rectangle hollow portion) to the English word that needs to be converted. And upon pressing a button (or autodetect), the English word is converted to Malayalam.

So, my question is how to extract the English text(or words) from the screen (which is seen through the hollow portion of the window.

Here's a screenshot of what I'm trying to do.
