[2008] Counting Numbers From A Listbox In A Richtextboxbox?
Jan 22, 2009I have a problem with my code.
first code
Private Sub BtnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnToevoegen.Click
Dim bytSum As Byte
Dim bytTotal As Byte
[code]....
I have a listbox with the numbers from 1 to 20 in it. If I add one of these 20 numbers, the number should be added in the richtextbox and they should be counted together with the last outcome I had. And this new outcome should be shown in label "lblTotal. If I add a new number into the richtextbox with this button. This new number should be added under the last number in the richtextbox and it should counted with the last outcome I had. This way I can count how many points I have.
Counting The Specific Characters?
Oct 1, 2009I would like to know how to count specific characters for a proper split value so I can seperate the name of the file from the rest of this address:
C:\Program Files\Folder\Folder\File.file
The reason is so I can combine it with other addresses taken in my code to cuase a proper copy command using the File.Copy with import IO The character I am trying to count is: \ This is so when I command the split, I can choose the split number (starts at 0) so if there are 4 of the "\" characters, then I would subtract one from this number, and use it as the Split index so I can capture the split data at: File.file
Counting Specific Items In One Dimensional Array
Feb 10, 2011I have one dimensional array that is being returned by an NVP function, the problem is that I want to count the number of ID's returned by the array to set the limit. For instance the array comes in this format ID0, ID1, ID3.... IDn, Name0, Name1, ...., Namen, Surname0, surname1, ...., surnamen etc... I want to know the n+1 number of ID's so that I can set it as the upper limit of my array to be able to loop through without setting an arbitrary number.
View 2 RepliesC# - Counting The Frequency Of Specific Words In Text File?
Dec 23, 2010I 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).

View 4 RepliesVS 2008 Listbox Specific SelectedIndex?
Feb 2, 2010I need to make events based on which index is selected in the listbox. I was wondering if there was an inbuilt function of if I need to use If conditions.
vb.net Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
That code will run when the selected index is changed regardless of which index. But I need each index/row to run a different event. I know I can use If conditions to get what I want, but I expect it'd be a lot more efficient with an inbuilt method.

VS 2008 Counting Down From 30 Mins?
Feb 7, 2010I'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.

VS 2008 Counting Occurrences Of Words In Array
Apr 9, 2009I 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.

Mar 16, 2012This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.
I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out.

VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

View 16 RepliesDisplay Data Below Specific XML Tag By Selecting From Listbox?
Oct 15, 2011I just started learning VB.NET about a moth ago (I have been taking classes, so its been about 5 days worth of classes) and I decided to work on this project idea I had. Essentially, it's a database to keep track of anime and manga that I, or whoever else uses it, have watched/read.[code]...
However, now I want to make it so that when one selects a specific title in the list box, it will show the data in the tags below the <series> tag that matches the item selected in a label. One thing I just thought of is than since the list box gets populated in the order that the series are in, it could be easier to go in order from first item equaling the first <series> and so on.
