Count The Number Of Times That A String Appears In Another String?

Jul 15, 2009

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.

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:

Client That Appears Same Number Of Times As There Are Keywords

Dec 13, 2011

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.

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]...

Count Occurrences Of Letters In A String?

Nov 4, 2009

QuoteWrite a Visual Basic Console Application which executes a Do-While loop repetitively. Each time the Do-While loop executes input a String value, count and display the number of occurrences of the letters �a�, �b�, �c�, �d� and �e�. Use at least one Select Case statement inside your Do-While loop. For example, suppose during one execution of the Do-While loop you input the following String value: �My mother is a great lady!�. Your program should input this value into a String variable, compute the number of times each of the letters �a�, �b�, �c�, �d� and �e� occurs and output the results: a � 3, b � 0, c � 0, d � 1, and e � 2. Terminate your Do-While loop once a value of �All Done!� is entered for the String value.

Here is my code:

Dim s1 As String
Dim a, b, c, d, e, count As Integer
Do While (s1 <> "all done")

Count The Occurrences Of Letters In A String?

Nov 5, 2009

My problem is an error that states Variable 'count' hides a variable in an enclosing block. Here is my project and my code so far:

1. Write a Visual Basic Console Application which executes a Do-While loop repetitively. Each time the Do-While loop executes input a String value, count and display the number of occurrences of the letters �a�, �b�, �c�, �d� and �e�. Use at least one Select Case statement inside your Do-While loop. For example, suppose during one execution of the Do-While loop you input the following String value: �My mother is a great lady!�. Your program should input this value into a String variable, compute the number of times each of the letters �a�, �b�, �c�, �d� and �e� occurs and output the results: a � 3, b � 0, c � 0, d � 1, and e � 2. Terminate your Do-While loop once a value of �All Done!� is entered for the String value.

2. In the same Visual Basic Console Application, following the Do-While loop described in step 1. above, enter another String value and modify it by replacing all occurrences of the word �hi� with �hello�; all occurrences of the word �today� with the word �tomorrow�; all occurrences of �hate� with �love�. Output both the original String value and the modified String value.

This is my code:

Module Module1
Sub Main()
Dim s1 As String
Dim a As Integer = 0
Dim b As Integer = 0

String Parse - Display Word Instead Of Just Count

Feb 17, 2009

I am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.

Here is what I have so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim strCity, strState, strZip As String
Dim strInput As String = txtInputData.Text
Dim intCount As Integer
'Obtain the count for city
intCount = strInput.Length
strCity = strInput.IndexOf(",")
lblCity.Text = strCity
