Search A HTML Document For Specific Text?
Jun 20, 2010
I have a simple HTML viewer and I would like to add the capability of searching an open document for a text value I specify. Below is an example I found on MSDN. VB gives me an error, "Selection" is not a member of "System.Windows.Forms.Application".
Private Sub SelectionFind()
Dim findText As String = "find me"
Application.Selection.Find.ClearFormatting()
If Application.Selection.Find.Execute(findText) = True Then
[code]....
What I would like to search is the content of a WebBrowser control.

What I am doing is creating a simple login and register system. I am going to save the information of each user into a text or ".dat" format and have them placed into a folder called "accounts".The small problem that I have is the "Forgot Password" option. I can't think of how to search all the documents for the e-mail or the username.So basically I need to know if it is possible to do a small search for the e-mail through all the documents in the "accounts" folder.
-I know another option may be databases...but I don't completely know how to use these.
-I have general knowledge of arrays

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.

Am writing a windows app using vb.net 2005. The app captures a string variable from the user. As each file within a directory is read, I want to match the stored string within each file. If I find a match to the string, I want a list box to be populated with the name of the file. I have added Imports System.Text.RegularExpressions and tried using the match collection.
For example: My direcotry has 5 text files. I want to match a string "PARENT" in the text of all these 5 files. The list box should output the name of each file where the string was found.

How do I search for the words with the same font size (e.g. 15) in a rich text box and put the words into a list box? For example, consider a dictionary whose word entries are of size 15 and the rests are of 12. So how do I put all word entries into a list box and then the description (of size 12) in another list box. I am using visual basic 2010. I've tried regex but couldn't find a way of specifying the font size.Consider the bold letters of size 15 and the rests of 12.[code](physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. 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.

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]...

I've been programming in VB.NET 2005, 2008 and now 2010 for almost 2 years. Just casual little applications, nothing big.In this project I need to parse links from a web page, it doesn't quite work though, it parses the names only and no links.I'll give you my code, let's say for a random page:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TextBox1.Multiline = True
WebBrowser1.Navigate("http:www.buyfixuse.com")
[code]....
If I activate this function in my application instead of links to the two blog posts on that website, it only gives out the text that is related to these links - (more...)

I need to write some code that opens a Word Document and then either extracts the data so that a HTML document can be created or simply resaves it as an HTML document. I've had a quick look around the net and tried adding an Object Reference to Microsoft Word Object X.0 Library to my Project. So that I could play around with things, but immediately It was telling me the following weren't defined.
Dim objWdApp As Word.Application
Dim objWdDoc As Word.Document
Dim objwdRange As Word.Range
Could anyone either explain what kind of thing I would need to do or link me to some useful tutorial.
