Number Of Times A Character Appears In A String?
Nov 11, 2009
How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:

How do I count the number of times that a string appears in another string. I know this code:
If odocument.ToString.Contains("window.alert") Then
pops = pops + 1
End If
But that will just see if the desired string contains "window.Alert" once, rather than how many times it does contain it.

I am trying to count the number of times a specific character is in a string. The problem is when I run the program the letter doesn't advance from "d" in the string "debugging" and doesn't display the number of time the character "g" is found.
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
Dim letterCount As Integer

I know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.

this is my first post in this forum! I guess my question is very simple. I just started with VB.net yesterday I want to search through a text string, and then count how many times a word appears. How do i do this? Is there some sort of function that i can use together with a loop of a kind?Something like the inStr(), just something i can use with mulitble appearences!

In my DataGridView, there is a column for names of machines in the database and I want to count how many machines of each time I have. I have set aside 1 text box with 1 label for each time of machine and in the text box, I want to display how many machines of that type are in the DataGridView?For example, I have 50 records and 30 of those records use machine "80ER" while 12 use "90E" and 8 of them are "PM100". I'd like the 80ER text box to show 30, 90E text box to show 12, and PM100 text box to show 8.

How do I check to see if the first character of a string is a number in VB.NET? I know that the Java way of doing it is:
char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');

I'm scanning through all characters in a textbox. Then the program counts how many of each character is in the textbox. Here's the code which adds all characters to a list:
For each c as char in TxtBox
list.add(c)
Next
Everything's working fine, except this will also add returns to the list, which I don't want. I thought I could write like this:
If c <> chr(10) Then
list.add(c)
End If

I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times
Public Class Form1
Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

I have a window form with a label. On the form I have a dataset, bindingsoure, and tableadaptor (all created by the IDE in response to binding the text property of the label) To fill the datatable, the IDE created this: Me.ClientsTableAdapter.Fill(Me.MyDataSet.Clients) Works fine. The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1

TimeN is system time. TimeF is a fixed date and time. All I need is the number of seconds between fixed and system(now) for timeR (and counting).

This text book i have is not very good at all. the exercise's at the end of each chapter ask u to code projects without first covering the basic of what u will need do to code them. (Programming in Visual Basic 2008 Julia Case Bradley + Aninta C. Millspaugh)
Design and code a project to calculate the amount due and provide a summaray of rentals. All movies rent for $1.00 and all customers receive a %10 discount. The form should contain input for the member number and the number of movies rented. INside a groupbox display the rental amount, the 10 percent discount, and the amount due. inside a second groupbox, display the number of customers served and the total rental income.(afterdiscount).Include buttons for Calculate, clear, print and exit. The clear button clears the information for the current rental but does not clear the sumarry information. A print button allows the user to print the form. Do not allow bad input data to cancel the program; instead display a message to the user.[code]...

I have an SQL database with a single table with several colunmns. I want to count how many times a certain number appears in one of the columns. E.g. I have the following:
A B C
8 4 6
0 9 3
1 4 6
4 7 1
I want to count the number of times 4 is used in column B. I have looked at using the following, but not sure if this is even the right approach:
Dim db as New MainTblDataSet
Dim BCount = Aggregate B In db.MainTbl Into Count(B.B = num)
where num=the number I am counting the instances of (4 in this case).
The hope is that BCount will equal 2, but it returns 0 every time.
