Find A Word In A String In Eng And In A String Of Unicode (no Space Between Each Word)?
Mar 6, 2009
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.
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]
I am working on highlighting a word when entered in a textbox.
Example:
string = "hi this is <b>testing</b>"
When i enter the word "testing" in textbox and click on search then it is highlighting the word "testing". but when i enter "is testing" in textbox and click on search then it is not highlighting the word "is testing". this is due to there is bold tag for "testing".
How can we highlight the word which is in bold tag...
I'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.
In a program used to find words from random scrabble letters how do you loop through each of the possible combinations of letters? ie: abc acb bac bca cab cba
As know mid(source, wordstart, wordlength) in VB6 source.substring(wordstart, wordlength) in vb2008 what differebce between both ?i can run it "mid(source, wordstart, wordlength)" at vb 6 with no problem,but i can't run it" source.substring(wordstart, wordlength)" at vb2008 'System.ArgumentOutOfRangeException' happened with System.Windows.Forms.dll
this is my first post in this forum! I guess my question is very simple. I just started with VB.net yesterday I want to search through a text string, and then count how many times a word appears. How do i do this? Is there some sort of function that i can use together with a loop of a kind?Something like the inStr(), just something i can use with mulitble appearences!
I am looping through a word doc where I need to find a string to replace and these are in text box's so I thought I could do something simple like this but its not working. vb For Each oRng In doc.StoryRanges Do strTxt = oRng.Text If strTxt = "textToReplace" Then [Code] .....
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]...
Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String 2- Create sub-string 3- Erase a portion of a sting 4- Replace a word in the string 5- Count number of words and characters in the string without spaces. 6- Capitalize first character of each new sentence and convert the rest of the characters to lower case. 7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
I am trying to write this loop to find the word start and then insert a word in a column until it sees stop and then go through all the data and do that.
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
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
i need to get a set of values after certain 14 length of a string and before the last 5 stringss.
Theboyisgoingt9123holdi: so i need to get the value 9123.iamfullofmeats89holdi: i need to extract value 89. so the algorithm here is, i am trying to extract the values that comes after the 14th length of the string and just before the last 5 characters of the same string. its always whats between 14th and last 5 characters.
I want to make a program like this example I make a assuming in here A is "00" B is "01" and etc and I put a text in my textbox example : "0001" and it will check every 2 word 00 become "A" 01 become "B" how to do that ?
I already try using a substring but I'm to confused how to set it can read every 2 word
I've got this problem where I'm supposed to be determining whether a string is a word or not. not exactly.Its supposed to just make sure each string has at least 1 vowel, and each vowel is surrounded by consonants. If it meets those requirements it'll be accepted, if not it'll be rejected, but I've already got that part figured out. I think I know a horrible way to do it, that would take a very long time, but I'm thinking there has to be a much easier way..
I have a string which contains words with parentheses. I need to remove the whole word from the string. For example: for the input, "car wheels_(four) klaxon" the result should be, "car klaxon".
for example. String= "Hi VBFriends, I am learning VB 2010."
i need to replace only VB as C#.
if i put String.Replace, its changing as "Hi C#Friends,I am learning C# 2010."
i used regex, Word boundary but not worked, below my code.
Dim sHTMLStream As String = "Hi VBFriends, I am learning VB 2010." Dim oColl As MatchCollection = Regex.Matches("sHTMLStream", "\bvb", RegexOptions.IgnoreCase) For Each sTemp As Match In oColl MessageBox.Show(sTemp.Value) Next
now i search for the word basic.if i press the button find. the first "basic must highlighted, and then if i press again the button the next "basic" is the highlighted one and so on.I already finsih that scenario. What i've done is that first im going to search all the positions of the word and then store it in a array. Then after the array populated with different location of the word that is searching. that is the time i call all the indexes of the array one by one. But i don't want my approach because imagine i have 10000 words. and i search for a word or letter. Lets say the result is 5000 match. so it needs my array to be size in 5000. what a mess in memory.
I don't want to used the FinsString or Find function of VB i want some algorithm to do this. Anyone have a easy approach..
I am attempting to write a very basic console application which simply counts the number of times a word appears in a sentence. This sentence is input by the user, as is the word to look for.(I also need this search to ignore the full stop and case, but I'll try and do that myself)For example:
Sentence: "This is the last time that I'll say this."
Look for word: "this"
Expected output "2" (as "this" appears twice in the sentence)
I have written some basic code below, however, the output is a boolean value rather than a count of all the times the word has been used.I have a very limited knowledge of VB, so the solution is probably going to be long winded and simplisitic. I am a mature student at university, hence the reason I am writing these odd looking applications.
Module Module1 Sub Main() Dim userSentenceInput As String[code]......
I am trying to replace an entire word in a string. This is my example string: "Hello test this is testing". I want to replace the word "test" with "abc". I want the output to be: "Hello abc this is testing". Whenever I try and use the Replace() function I get: "Hello abc this is abcing" How I can do this with Replace or RegEx
