View 3 RepliesI have used examples from threads here on how to open and convert word documents to html in order to parse them. I got it all working great using the office interop library but used an example word document with some text in it and it worked fine. Now with actual word documents that I need to parse that come in all types of formatting and irregular formats I got it to convert to html all fine. But the actual html when looking at it does not make sense and I am not sure how to parse this. for example:
LsdException Locked="false" Priority="72" Name="Colorful List Accent 5"/>
<w:LsdException Locked="false" Priority="73" Name="Colorful Grid Accent 5"/>
<w:LsdException Locked="false" Priority="60" Name="Light Shading Accent 6"/>

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 8 RepliesI'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")

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.

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".

Dim findText As String = "find me"
Application.Selection.Find.ClearFormatting()
If Application.Selection.Find.Execute(findText) = True Then

What I would like to search is the content of a WebBrowser control.
What is the best way to write data from a hierarchical set of objects to a file? The highest order parent has 1000's of children all with children (DOM style). Trying to traverse the tree and creating one big string which is then written to a file is throwing an out-of-memory exception while creating the string.
Details I've created a set of classes that make up an HTML document. There was control that I needed that the pre-packaged HtmlElement and HtmlDocument didn't give. The Document Object Model is maintained throughout, with some similar methods and properties and such. I'm using the custom classes to create a very large HTML document. When I say large, I mean on the order of over 2000 printed pages. It's doubtful that they will all be printed, but some will be.
My base HTMLElement object, from which all other objects are derived, contains an OuterHTML property which, as expected, gets the full HTML of the calling object and the HTML of all child elements. After the code which generates the report runs, I have my HTMLDocument object containing the entire report which needs to be written to a file. Here is where I keep running into problems.
If I call OuterHTML on the HTMLDocument object, I get an out of memory exception.
Other reports have saved fine, but this is by far the largest report I've thrown at my HTMLElement object. My assumption is that the property call is generating too much text.
I am basically just creating a new .HTML file, opening it for reading, and writing in all of the text. Like:
File.WriteAllText(FileName, HtmlDoc.OuterHTML)
How can you find a specific HTML element in a webbrowser.document? I'm making a program that will go to a specified address on the internet and find a html element and get the src link from the element then return the src to the imagelocation of a picturebox. Is this at least possible?
View 8 Repliesi have a windows form that has a web browser control.
i need to pass the value from the windows form to the html doc.
here is my problem.... can pass the value across to to a function in the html page but when i try to pass the same value to an image tag in the same document it does not read the value.
here is my code from the winform
If e.Url.Equals(wb1.Url) Then
wb1.Document.InvokeScript("fetchImage", New Object() {path})
End If
it passes through the variable 'path' to a function in the html doc.
heres the code for the html doc.... this part of the code works
function fetchImage(path) {
var now = new Date();
var zm_image = new Image();

View 1 RepliesSo, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.

View 5 RepliesWe receive an HTML document in an email which has some special pricing and products. I want to be able to parse the data, perform some lookup operations on it, assign some pricing markups, save it to a data source for future referance and do it with VB.net and a web browser. I'd really like to use MSHTML.HTMLDocument, but all the documentation I have is based on HTTP URL's, but since these HTML pages will be opened from an eMail or saved to a fileshare, they won't have the HTTP. I've also tried to read it as a text file and parse with RegEx, but it's not very effecient and to be honest, RegEx is still a fog to me.
Would anyone be kind enough to suggest a way to do this? Is MSHTML able to do it and if so; how do I set up a reference to a non-HTTP URL?
I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.

View 1 Repliesin an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

How can I write the resulted stream to be sure I can read it again later?
I am trying to build my own website and realized that it would be a big help to also create my own vb program to enable me to embed tags with simple clicks of buttons. I am having trouble getting my vb code to be compatible with html code (I keep getting vb syntax errors).
Here is what I've tried:
<strong>'Inside of a button:Textbox1.text = "<html tag example></html tag example>"</strong>
Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.
