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.
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:
This is what I have, but It doesn't work with strings for some reason (only text files):
[Code]...
input = "my mother is a great lady" output = A -3, B - 0, C - 0, D - 1, E - 2
I wanted to count the number of times letter A - E is in the input string.
codes like(x is variable)
dim k as string="5b5" & x & "85"
I want to know how many times "5" appears in k,
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!

View 2 RepliesIn 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.
View 7 RepliesI 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.

I'm looking for a way to determine how many times a character occures within a string.
Let's say for example I want all comma's to be counted in the following string:
'122,333,222,11,44,55'
How can I retrieve the number of comma's? in example 5.
ExamplesIF the user enters a 00001 the count would be 4If the user enters a 0811 the count would be 1

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

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'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

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")

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
