View 1 RepliesHtml Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?
Jan 10, 2012This 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?
Insert HTML Or RTF Formatted Text Into Word Bookmark?
Jul 5, 2011I try to insert formatted text into Word bookmarks. The text comes from several rich text controls (we use TX Text Control) and is appended into a bookmark. The problem is that the tags are written as-is and are not interpreted.
oWord = New Word.Application
Dim strFileName As String = "\...Template.dot"
oDoc = oWord.Documents.Add(strFileName)
[Code].....
I tried with RTF or HTML format for my string but it is the same behavior.

Jan 3, 2010I have another question.I have taken an HTML file called "template.html" and got its content. Then I change some variables and save it to a new file in the same directory. Afterwards, there is something else I need to do before saving but I don't know how.In the template.html file, I have a table which should represent a table from a SQL database which means I would need to loop it. But I don't know how to loop that.

[2008] HTML Content From A Frame?
Feb 3, 2009I want to read the HTML from a frame in a web page. I have started with a WebBrowser, which I browse through manually, attempting to scrape the details as I go. The reasn for using Web Browser is that it involves a complex form, which I can't really replicate in code.If I directly query the WebBrowser info I get very little, and the frame data id represented simply by a FRAME TAG, and a simple URI with no form data (it needs the data to return the content)I tried the Web Browser documentStream, and again I get very little.The closest I got to the full HTML is the following code. However it is missing the OBJECT tag and it's contents, which is what I absolutely need:
htmlwin = wb.Document.Window
For Each frame As HtmlWindow In htmlwin.Frames
For Each el In frame.Document.All

View 1 RepliesLoading HTML Content Into A WebBrowser Control From Memory?
Oct 4, 2005WebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

Stripping HTML Function Within Text Areas Content
Mar 10, 2010I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?
