I've got to generate html files with text data containing > < " and other punctuation and special characters. I 'manually' replace them with < > and " and I wonder can it be done using some .Net Framework class?
Also I'll be interested in 'unescaping' such sequences back to characters.
I have a block of HTML which I want to write to a file. It contains about 30 lines and it's difficult to escape all the double-quotes in individual WriteLine statements. In PERL, I can do something like the following to write inline HTML and print everything upto <<OUTFILE to outfile as-is, is that possible in VB .Net 2008?
print <OUTFILE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD><TITLE>GSC Signature</TITLE>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type>
<META name=GENERATOR content="MSHTML 9.00.7930.16406"></HEAD>
<BODY><<OUTFILE
I could save the HTML in a template file and copy it into a new file each time, but that's not very flexible.
I have inherited a database that is moving to the web. Problem is that some of the string fields have html characters....
One example is....
"" without the quotes, IT WON'T SHOW UP IN HERE EITHER, trying something else. At any rate it has < and the > signs with text in the middle.
How can I escape any possible combination of html references.
SelectCommand="usp_getSingleStringData" SelectCommandType="StoredProcedure"
<SelectParameters>
<asp:SessionParameter Name="shrtText" SessionField="shrtText" Type="String" />

Question regarding fluent nHibernate table mappings:Apparently I was under the mistaken impression, that with an ORM tool, such as nHibernate, one could gain database independence - at least in table creation.Now, I have an automated toowhich creates fluent nHibernate mappings for me.It also works fine (though only if ALL tables have a primary key...)
Here a good representative example for such a mapping as it is created by the program

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?

AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).

I'm making this 'help' popup form to my webbrowser. And I need to know how I can put html text into my form. Is there other ways I can do it ?
View 3 RepliesI need to create a VB.net app that automatically reads a html table. It should connect to a web address (eg "[URL]") and read it. I'll be happy if I could just get the full HTML. I was able to use this code to get the HTML of a regular website:
Dim strReply As String = "NULL"
Dim objHttpRequest As HttpWebRequest
Dim objHttpResponse As HttpWebResponse
objHttpRequest = HttpWebRequest.Create("[URL]")
objHttpResponse = objHttpRequest.GetResponse
Dim objStrmReader As New StreamReader(objHttpResponse.GetResponseStream)
strReply = objStrmReader.ReadToEnd()
This code sample will give me the HTML for the website [URL]. However it will not work with the website I want (eg "[URL]"), because when you access it via regular browser it will popup a browser dialog asking for credentials (user / pass). So when I run the code above for it, I'll get the exception:
The remote server returned an error: (407) Proxy Authentication Required.
How do I set this up to use the credentials, before retrieving the HTML? This is actually my first web-related app.
