I have a question that relates to identifying words or characters in text boxes.Okay, I know that I can identify the entire text with textbox1.text = "~~~~". But say I want to search for a specific part.e.i.(in textbox)Hello, how are you?(in textbox)How, in code, would I find and select, let's say, the word "how"?Please, if you can help, I need it. I want to learn as much as I can about Visual Basic so I can become a better programmer.

I have a text file stored as a string variable. The text file is processed so that it only contains lowercase words and spaces. Now, say I have a static dictionary, which is just a list of specific words, and I want to count, from within the text file, the frequency of each word in the dictionary. For example:
Text file:
i love love vb development although i m a total newbie
Dictionary:
love, development, fire, stone
The output I'd like to see is something like the following, listing both the dictionary word and its count. If it makes coding simpler, it can also only list the dictionary word that appeared in the text.
WORD, COUNT
love, 2
development, 1
fire, 0
stone, 0
Using a regex (eg "w+") I can get all the word matches, but I have no clue how to get the counts that are also in the dictionary, so I'm stuck. Efficiency is crucial here since the dictionary is quite large (~100,000 words) and the text files are not small either (~200kb each).

I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

At the moment I'm using:
For Each book In books
result.Add(File.ReadAllText(book).Substring(0, 500))
Next
Return result
to display the first 500 characters of an rtf file I'm drawing from in earlier code, but I'm now wanting to specify line - for example lines 4 - 20.I can't find any way to get this to work as when I change the above code to:
For Each book In books
result.Add(File.ReadLines(book).Substring(4, 24))
Next
Return result
I get massive issues stating "Substring is not a member of 'System.Collections.Generic.IEnumberable(Of String)" I feel like I'm literally 1 line of code away from this being fixed but cannot get my head around it.

I have the following code that replaces an item in a richtextbox with a new one. Reg-replace works fine but only when the pattern matches only one value. When there are two similar values in the richtextbox it matches them both. How can I replace based on specific lines?

I have a RichTextBox.
I want to input an integer and the RichTextBox to go to that line and delete all lines above it.
For example, if I have 100 lines in the RTB, and I specify "25" as the integer, I want lines 1-25 deleted and for the RTB to keep 26-100.

What I would like to be able to do is to take data from textbox1, textbox2, and textbox3 and modify the "Y" variables in lines 5, 14, and 15 by the value of textbox1. The "X" variable in line 5 needs to stay constant while the one in lines 14 and 15 change to the input of textbox2. Textbox3 needs to modify the "F" variable in lines 3 and 14. Then the whole text needs to be written out to notepad

I'm working on a program which should edit a text file by adding/deleting some specific lines.By default this text file doesn't have these specific lines, so the program will add them.But I also want it to replace them if they're already in the text file.Basically this is my idea:- Read the text file- Search the specific lines- If they exist then replace them

I'm using this code to load a text file into list box.
r = New IO.StreamReader(str)
While (r.Peek() > -1)
ListBox1.Items.Add(r.ReadLine)
End While
r.Close()
But it loads the whole file into list box. I only want to load those lines of text that contain following number: 2008. It doesn't matter if the "2008" is at the beginning, middle or the end of a line.

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).
Here is my
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)
[Code]....
Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?

I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:
Code:
Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click
Dim trackname As String

I am creating a simple researcher application to access and store data. As of today it workes by entering a number into a text field and hit enter/button. The result then shows up in a non-menu webbrowser window. What i would like it to do was to exclude the web browser window, and instead show in a popup window inside the application. This should be rather easy, here's what i think might be a problem. I want only to show specific lines from the webpage, not the whole page.
