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 am trying programming a program that open a txt file then get specfic data from each line then put the data1 in a textbox1 and data2 in textbox2.[code]and for each time i don't now the username or the password i want the programe to search in line 1 the word between "user=" to "" and the word between "password=" to "".I created the text reader and i hope that same one can help complete the project.[code]
I'd like to know if anyone has a code for or can direct me on how to select keywords given in a speech command and to ignore the other words. Example: Speech "The beach looks great today"
I want to use the word "beach" to trigger a function and ignore the rest of the speech.
I want to make visual basic read between <strong> and </strong> , and take out the "welcome back,".I want it to just say "itoknc". How could I do that with inner html?
I need to check for specific words so that the program will know what smtp client will be used. For example. If the from textbox will have @yahoo.com on it then the program will make use of the smtp for yahoo.
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.
Let's say I have a textfile which contains paragraphs. Some of the paragraphs start with * or a > character. How do I index the words that start with these characters?
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?
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

What I want is when I copy the text into clipboard and paste it to the TextBox, the Textbox only displays the third line (the phone number). It should look like this :
when using stream reader to read text files how would i go about reading or referencing specific lines.so if i wanted to read from say line 2, 3, 4 or 10,11,12 in the textfile or what ever.
I have 2 text files that are formatted in standard XML One of them contains some lines that need to be copied to the other. What i am trying to do is search through the first file until i see the string "<Segment" then copy all lines into a rich text box up until the string "<segment/>" I Then want to look through the other file until i find the string "<Jointfree/>" then copy the contents of the rich text box to underneath the Jointfree String I Also need to search the second file until i find the string "<Markers/>" and then paste some text into the line above the markers tag.
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?
as per title, I want specific lines in listbox as bold or with colours.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim xyz() As Byte = {&H1B, &H0, &H10, &H1B, &H0}
ListBox1.Items.Add("XYZ: " & read_write_str(deviceHandle, xyz, xyz.Length))I get reply from device for i.e. 1234567890, I want this to be in BOLD or if I could add colours to it.
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.
