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!

How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:
How do I count the number of times that a string appears in another string. I know this code:
If odocument.ToString.Contains("window.alert") Then
pops = pops + 1
End If
But that will just see if the desired string contains "window.Alert" once, rather than how many times it does contain it.
codes like(x is variable)
dim k as string="5b5" & x & "85"
I want to know how many times "5" appears in k,
I am testing for a string if it contains at least n chars in consecutive order: I have this regex but it doesn't seems to work (w1){3,}
View 2 RepliesHow would I find all instances of a letter if it appeared multiple times in a word? For example if I had the word 'mississippi', how would I find every 's' or every 'i' or every 'p'?
I know how to use the string.IndexOfMethod() so I was thinking I could find the first letter, mark that position, and search again from there. Then I would keep looping until the end of the letter. But I'm not sure how to signal the end of the loop.
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 know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.
View 1 RepliesIn my DataGridView, there is a column for names of machines in the database and I want to count how many machines of each time I have. I have set aside 1 text box with 1 label for each time of machine and in the text box, I want to display how many machines of that type are in the DataGridView?For example, I have 50 records and 30 of those records use machine "80ER" while 12 use "90E" and 8 of them are "PM100". I'd like the 80ER text box to show 30, 90E text box to show 12, and PM100 text box to show 8.
View 7 RepliesI 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...

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.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?
I am currently using the code below within a VB.Net application to find specific text in a Word document. The text is surrounded by symbols represented by the character codes in the .Text statement. The code below is working fine. The issue now is that sometimes the desired text within a document has been marked for deletion and appears as tracked change within the document. I would like to find only the desired text that has NOT been marked for deletion. Does anyone know of a way to determine if the found text is a deletion?
