VS 2008 Counting Occurrences Of Words In Array

Apr 9, 2009

I am in a "survey of programming languages" course and have a professor who doesn't teach. There is no text book for this course.I am working a VB Form project to take a URL, grab the HTML source code, parse out all words, and count the occurrences of each word on the page. I have built the form, and written the code to parse the words and store them in an array. What is the most efficient way to count the occurrences of each individual word in that array (case insensitive), sort the results decreasing from most frequent, and display the results of the ten most used words. I will be displaying the results in two separate listboxes on my form. 1 listbox shows the words, and the other shows the number of occurrences.

I have to search within an array and display the number of occurrences that a value within the array appears. I know that my code is incorrect but this is what I have so far. If anyone can point out what I am doing wrong that would be great.

C# - Counting The Frequency Of Specific Words In Text File?

Dec 23, 2010

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).

Find Out Number Of Occurrences Of An Item In Array?

I'm using Streamwriter/Streamreader for the first time in this project and keep getting an "Argument out of Range Exception was unhandled" error.It says "length cannot be less than zero. Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value?

I want to search for an array of words, like Boeing, Airbus, Saab etc there might be 3 options there might be 5 options in this array that i'm looking for.

Counting Columns In ASCII Text File To Enter Data Into An Array

Nov 21, 2009

I am using visual basic 2008 and trying to create an application to plot data from text files. I have several data files of various sizes. They have an unknown number of rows and either 2 or 4 columns.I need to put the data into 2 dimensional array, so value(,) becomes either value(lines,3) or value(lines,1) depending on the number of columns.My program needs to be able to count how many columns there are, and redim value(,) appropriately.I have written a piece of code to count the number of lines (rows) in the file using 'While not (EOF(1)) ....' but I'm stuck on how to count the number of columns.I could ask the user to indicate how many columns there are before the file is read, but I would prefer the program to detect the number automatically.

Asp.net - Search Database By Using An Array Of Words?

Dec 6, 2011

I'm attempting to setup a search function from a string a user types. (ex: "John Doe" or "Doe, John") I was thinking I would use Replace(SearchString, ",", "") to get rid of the commas the user might enter, and then use Split(SearchString, " ") to get all the words into an array. Once they're in the array I would execute a Stored Procedure on each of the terms and build a DataTable with the results.

Below is what I'm wanting to use for executing my stored procedure.

oCommand = DataAccess.GetSQLCommand("MyStoredProcedure", CommandType.StoredProcedure, SourceServer.ConnectionLocal)
oCommand.Parameters.AddWithValue("@MySearchString", SearchString)

[Code]....

Now I'm thinking the "SearchString" I will assign while looping through my array of words... but this doesn't seem like the right way to do this. Maybe it is but I don't know how to append my next result to the previous DataTable either.

VS 2008 Counting Down From 30 Mins?

Feb 7, 2010

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<

Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.

My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.
