View 14 RepliesI 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'm trying to create something like a tooltip suddenly hovering over the mouse pointer when specific words in the richt text box is hovered over.

View 2 RepliesI've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I'm using DevExpress.XtraRichEdit (2010 2.8) My problem is, this control does not have some basic functionality as does the Standard RichTextbox Control that comes with VB.NET (2010). However it does have functions that the standard RichTextbox does not have. With that being said, I'm trying to create a procedure to go to a specific line in the control. The control does not have the same procedure as "Richtextbox.GotoLine" The procedure below works with a standard Richtextbox. Basically, I'm trying to create a procedure to go to a specific line in the richtext control.
If txtLine.Text <> "" Then
Dim MyText As MainForm.RichTextBox.Text

Here's my problem i am trying to extract data from a forum
Now what i want is to remove a specific word from only a specific line
So here's a example
[quote=randombla13] I am the king of the world bla bla
[img]http//google.com/img.jpg[img]
[quote]This line should not be removed[quote]
[quote]
Now as you can see these are the codes you may have seen in many forums
Now want i want .Net to do is filter the the content in a textbox
And remove only the lines marked with red "[quote=randombla13]" from the first line
And the Extra "[quote]" from the end line
As you can see in the example the content has two "Quotes" so i jest want to remove only one from the first line and last line of the content
And note "[quote=randombla13]" the length after the = is Unknown it maybe of 6 characters or less or more
How do I get a specific line of text from a RichTextBox? And what is the string array control for? Can I use it to alphabeticalize the lines?

I am reading a text file line by line using StreamReader.Readline(). After reading a line i have to check whether some fields of the line which is read are present in the rest of the file or not. What i am doing is that after reading a line from the file i am passing the streamreader to check whether there are multiple entries. i am trying to use line.Length() to get the length of line, so using this length i can go back to the line
my code:
Dim pos as Long
sr = File.OpenText(filepath)
While sr.Peek() <> -1
[code]....
my problem is that it is not giving me the expected line or it is skipping some part of the line.how can i return back to my line?

View 4 RepliesMy text file look like this[code]...
I want to extract those lines according to value in ( ).
I was wondering how I would go about replacing a specific line of text with different text, and then later reading a specific line of text (from the same file). The text file has a lot of lines, and basically the layout is like this:
Something1 Data I want to read
Something2 Data I want to read
Something3 Data I want to read
Each line has a specific word, and then after that word is the data I want to use for the form.
How to read from a line in vb .net, I need to do the following:
change the line in a text file
[Path] = "c: hiscertainpath"
With this line
[Path] = "c: hatother

These paths will most certainly be different lengths, so I need to either replace what's in the quotes or erase the line completely and enter a new one, but in the same spot, not appended to the end of the document.

View 3 RepliesI have been learning VB for about 3 months now at college and decided to enhance my skills by making my own project at home. My project is basically a game where you have to guess if the next number will be higher or lower than the previous version and you can place bets on it. I have done all of this ok but I wanted to create a high score system so that you could save your score.I can manage to write out to a text file ok so that it looks like this
Highscores
Name
Score
[code]....
etc. But I am not sure on how to read in a specific line. So for example I want lblHighscore1.text to equal line 3 of the text document (as vb counts the first line as 0) So far all I have is this;
Dim objReader As IO.StreamReader = New IO.StreamReader("C:UsersKarlDesktopHighScore.t xt")
lblHighscore1.Text = (objReader.ReadLine)

Okay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.)

What is the quickest and easiest (and painless) way of doing this?
