I have a string which consists of the raw HTML of a webpage. I would like to search for the first use of /imgres?imgurl= within the string and display the url of an image which follows exactly after it in a text box. Below is an example of part of the string: [URL]..In this case it would find /imgres?imgurl= then it would display [URL]...
View 2 RepliesI 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'm trying to write a function to find a word in a string in the this format : "ThisissometextthatIneedtofindandthisisthetext. This is another text."It's read as " This is some text that I need to find and this is the text. This is another text." but there is no space between each word. I want to get the word "text" or any word in that string. Can you help me with this function with a code sample ?
And I think that this method can be implemented with a string of Unicode also because in a sentence of Unicode it contains one or few, sometimes zero spaces between each word.
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 have to search a string for a few words eg, dog, cat, lion but i want regex to fail if lizard is found in the string even if it contains cat, dog or lion.ismatch(pass) "dog|cat|lion" "This is not your average cat!"ismatch (fail) ??? "This is not your average cat! It's a lizard."??? - here the regex statement is unknown word spaces and boundaries or lower/uppercase is not a concern. I run the string through Replace(" ", "").Trim(" ").ToLower before handover to Regex.
View 3 RepliesI've been hammering at this over the weekend with no joy - been through page after page of RegEx Language documentation too.It's very easy to negate a match on characters. For example:
Dim MatchString As System.String = "<test0><test0><test1></test1></test0></test0><test0></test0>"
Dim NegationPattern As System.String = "([^<>])"
Dim RepStr As System.String = ""

Ive been searching the Stackoverflow but couldnt find the exact thread that my problem is this, i want to be able to find and take out any occurances of 8 digits wihtin a string.
Dim SetOfMatches As MatchCollection
Dim MyRegex As New Regex("A^d{8}$A")
Dim TestString As String = "testing 12345678 testing"
myMatches = myRegex.Matches(TestString)
For each Row as Match in myMatches
console.writeline(row.value)
Next
this doesnt not generate any hits. but i want to find the 8 digit occurance in the middle of the string.

I am trying to create a function that searches each line of a richtextbox and returns that row if one of many search phrases are found.The app works wonderfully when used with longer words or muli word phrases as the search criteria.The problem I have is if the search word/ criteria contains a small string such as bae or sp then I get alot of false positives. Anytime bae or sp is found within any word it returns the results.I need the function to stop looking within the words for results and instead look at the word as a whole for a match.Below you can see that I am taking each line of text in the richtextbox, removing most non-alpha numberic characters and replacing them with spaces.Then I have it remove any double spaces with single spaces.For the search term list I have it take the text before the delimiter;and do the same.Trouble I am having is,if the search term is SP and the search phrase is "This is a space shuttle lauch"it will return the sentence since the sentence contains the word "space" which starts with sp.[code]

View 2 RepliesI'm trying to find some words within a string so I can use them as headers. The string has different characters involved like letters, numbers, colons and so on. I've used the Mid function but it wouldn't work if the amount of characters in the string changed. The string isn't automatically coded in as it's a text file that's uploaded.There are multiple words I need to find within the string also.

View 3 RepliesI am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.
Here is what I have so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim strCity, strState, strZip As String
Dim strInput As String = txtInputData.Text
Dim intCount As Integer
'Obtain the count for city
intCount = strInput.Length
strCity = strInput.IndexOf(",")
lblCity.Text = strCity
End Sub

I have used Webbrowser control in editable mode.I am using IHTMLTxtRange for find a word and replacing it with other word.I have to find and replace internally in my code.Following is my code:-
Public Sub FindReplaceText(ByVal sfindText As String,
ByVal sReplacetext As String)
Try[code].....
It works fine for all find and replace except if the word contains vbnewline.E.g If in webbrowser control I enter 'Hii <vbnewline> Hello'The above two words contain Enter key(i.e vbnewline) between them.If I pass following string to my Method it doesn't recognize the whole word and doesn't replace the word. I have called my method as
FindReplaceAll("Hii"+vbnewline+"Hello","HiiiHelloReplaced", False, False)
Does IHTMLtxtRange support vbnewline in Findtext method?If not how can i do? All the above Find and repace need to be done in code and not by popping up the form for find and replace
