How to strip html code from a string? I know how to do this in Visual Basic 6 using Regular Expressions 5.5 as a reference, but since I switched to VB.NET 2008 today
View 1 RepliesI'm importing data from 1 database to another. I've been requested to strip all HTML content, as its messy and not valid, and just keep the links. I currently use the following VB.NET function to strip all HTML tags from a string of content:
Public Shared Function StripHTML(ByVal htmlString As String) As String
Dim pattern As String = "<(.|
)*?>"
Return Regex.Replace(htmlString, pattern, String.Empty)
End Function
I'm looking for a way of stripping all, but a (anchor) tags from the content. For example if I have the following HTML content:
<table><tr><td>
Lorem <a href="[URL]">Ipsum</a>
</td></tr></table>
This will simply become:
Lorem <a href="[URL]">Ipsum</a>
How can I do this?

The projects program is designed to open files output by another program, allow the user to edit the files content, then send the file to a specific bookmark within a word template. Unfortunately most of the output files by the 'other program' are html format.Question Is there a way to strip out HTML from the file when it has opened in my text area within the program? I found one or two online guides but haven't managed to get them working.
View 4 Replies"Form1" has a ToolStripContainer1.TopToolStripPanel which contains a ToolStrip with buttons. The buttons work on ONE click when "Form1" is active.If I click on another window and then return to "Form1" the ToolStrip buttons take TWO clicks to activate.The first click returns focus to "Form1" and the subsequent click fires the button event.I want the buttons to work on the first click and not require two clicks.Note that ordinary buttons on "Form1" that are not part of the ToolStrip work on the first click when returning from another window/form?

View 11 RepliesThis 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>

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?
Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
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).

Need to return the greater of 3 values. Each value is based on user input and system calculations. Requirement = the greater of (Req1, Req2, Req3) Have tried a number of "If" "Else" and Ifs within Ifs "<" and ">" combinations without consistant results. This may seem simple to some but I am relatively new to VB. My search on MSDN was not fruitful.
View 11 RepliesThis makes no since to me I have a textbox that the user will put in information that I need to cut off so I wrote this code
txtMatID.Text = Trim(Mid(txtMatID.Text, 1, (InStr(txtMatID.Text,
"-") - 1)))
The user will imput a number value then a - then some words after that. I just want the number value. But when I try to debug the app it breaks on this line of code with this error. Argument 'Length' must be greater or equal to zero.
In my decryption statement I am getting
Argument 'Length' must be greater or equal to zero. is this statement wrong

check to see if length is zero AND thereofre try again in a moment, (because it usually works second time for some reason). I can think how to get around the exception

View 2 RepliesI have two columns of numbers that hold team scores for different events. I am looking for a OO way to Color the textbox of the team with the highest score in each event. I know the following will not do it (without writing a complex set of If Then Statements) but I think it might paint a clearer picture of what I am trying to do.
VB

View 3 RepliesI thought I had this sussed until I then wanted to filter between two values or greater than or less than two values. I have searched and searched all over the web for this and I just go round in circles. This is so frustrating why is this so difficult to find something so basic (anyway that is my rant). I have something like this but am totally confused and do not understand what I am doing now: how I get this working in plain English.
Me.BindingSource.Filter = String.Format("DeliveryDate >= #{0:MMM/dd/yyyy}# And DeliveryDate <= #{1:MMM/dd/yyyy}#", dtpStartDelDate.Value.Date, dtpEndDelDate.Value.Date) _
& String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
If I run this with just the date range filter it works fine it is when I add the second filter for the Job ID range I get the following error; {"Syntax error: Missing operand after 'JobID' operator."}
So I it is this line I have the problem with:
String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
Can I do this to find the lowest value in an array greater than zero?
