Use Regex To Find A Dynamic Text?
Nov 29, 2009
I'm needing to use Regex to find a dynamic text. It will always be found between the same things. Now, I'm sure that made little sense, so let me clarify. I have a rich text box full of text. I am needing to use a Regex method to find a certain string of that text that is always different. This string will be located between the same two pieces of text every time.
For Example: If this is my string: id ="user_name" ><img style ="display: block;" usr ="resentful" I need to find the text in between id ="user_name" ><img style ="display: block;" usr =" and ".

I have the following html contained in a string.
<tr>
<td>Hello</td>
</tr>
[Code]....
I would like to use RegEx to find the <tr></tr> that contains the text "World". The difficulty is that there might be other <td> around the one that contains the search text. So we need to be able to search for the <tr> and </tr> nearest to the search text with any text between the <tr> and the search text.
The result of the match would be.
<tr>
<td>World</td>
</tr>
I'm using vb.net by the way.

$source |% {
switch -regex ($_){
'<'+$primaryKey+'>(.+)</'+$primaryKey+'>' {
$primaryKeyValue = $matches[1]; continue; }
}
I want to use dynamic key value with switch-regex, is that possible?

I need your help to find the right pattern to extract a string that i need.. The problem is that i have to extract all there is between this caracters:<a href="/url?q=(text to extract whatever it is)& I tried this pattern, but it's not working for me! : /(?<=url\?q=).*?(?=&)/
i'm programming in Vb.net, this is the code, but i think that the problem is that the pattern is wrong:
Dim matches As MatchCollection
matches = regex.Matches(TextBox1.Text)
For Each Match As Match In matches
listbox1.items.add(Match.Value)
Next

I need to find illegal characters in a windows forms textbox
The textbox text is sent as an sms text message and illegal characters are not allowed
e.g 1 client pasted some text from a word document into the texbox and the ' in msword appears as slanting ' in the textbox (see below)
e.g msword text - This is a new test of the Services
after pasting in textbox - This is a new test of the Services
The sms company have advised the slanting apostrophe is a unicode character
How can I find characters like above so I can remove them before sending the sms text

I am using a simple regular expression (in C#) to find a whole word within a block of text.
The word may appear at the beginning, end or in the middle of a the text or sentence with in the text.
The expression I have been using word has been working fine however if the word included a special character (that has been escaped) it no longer works. The boundary is essential so that we do not pick up words such as vb.net as a match for .net.[code]...

I have to match string like "DAY1","DAY2","DAY3"....."DAY31" with regex in vb.net. I tried something like this - ^?DAY(0[1-9]|[12][0-9]|3[01])$ but it did not work.
The pattern should have succesfull match if the source string is either DAY1 or DAY2 or DAY3 to DAY31 like so.

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.
On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.
I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"
Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
Me.Controls.Add(t_0300)

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,
Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs
So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"

i want to select the next piece of text which is underlined. You see the rtf of a richtextbox has following code for an underlines text :
uli0 hello friendulnonei
But the normal text looks like underlined. What i want to do is on a click of button the rtfbox should select the next piece of text which is underlined. An example piece of text is :
hello [friend your] house [looks] amazing.
imagine the words within square brackets are underlined. When i first click button1 "friend your" should be selected and on next click "looks" should be selected. Kind of keep moving forward and keep selecting it type of application. I know this can be done using regex but can't build a logic.
