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?
Example:
[code...]
Dim rand As New Random Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles random10.Click Dim count As Integer = Words.Items.Count Dim indexesList As New List(Of Integer) Dim rnd As Integer Do rnd = rand.Next(0, count) 'Ensure no word is selected more than once.>> If indexesList.Contains(rnd) Then Continue Do indexesList.Add(rnd) Loop Until indexesList.Count = 10 Dim generatedIndexes() As Integer = indexesList.ToArray New_Words.Items.Clear() For index As Integer = 0 To 9 New_Words.Items.Add(Words.Items.Item(generatedIndexes(index))) Next End Sub
View 2 RepliesHow would you select the last part of a string starting at a specific character count. For example I would like to get all text after the 3rd comma. but I get an error saying "StartIndex cannot be less than zero."
Dim testString As String = "part, description, order, get this text, and this text"
Dim result As String = ""
result = testString.Substring(testString.IndexOf(",", 0, 3))

View 5 RepliesI have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?

View 2 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 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.
