C# - Remove Duplicate Char On String (more Than 3 Occurrences) Using Regex?
Jan 13, 2012
I'm sorry if it's a duplicate of some question but this is specific on Vb.Net Regex function.
I need to remove any occurrence of 3 or more duplicate characters on a given string. For example:
Dim strTmp As String = "111111.......222222 and 33"
Dim output As String = Regex.Replace(strTmp, "????", "")
Debug.Print(output)
The "????" part I guess should be the Regex expression, which I must assume I know almost nothing about.
I don't know if that's the correct syntax. But I need the output to come as:
"1.2 and 33"

The following code:
If checkboxList.Items(i).Selected Then
.Fields("DESC1").Value += checkboxList.Items(i).Text + ", "
End If
should produce output such as "A, B, C,(space)", which will then be bound to a dynamically created GridView. I would like to remove the last two-char string, that is ",(space)". How can I do this?

how to remove or replace specific characters from a string. The code sample is provided contains a VBScript function to parse a string, replacing or removing any character found in the array declared at the beginning of the function.VBScript String Clean Function - Remove/Replace Illegal CharatersThe function was originally writted to remove illegal characters found in a string for use as a document file name in SharePoint Document Library.To use the function, simply update the array at the beginnning of the function to include all of the characters which are to be removed or replaced. If replacing specific characters with something else, the you will need to set inside the finction the string which will replace each character if found.The VBScript function then returns a cleaned string.VBScript String Clean Function - Remove/Replace Illegal CharatersBlogs: SharePoint Development | Web Development & Programming | Webmaster resources & free SEO

I have a string with 60000+ characters. I look for informations inside the string in a sequentially order. Every time I found a information I delete whatever is behind that information. In other words I reduce the size of the string every time I find something, and I do this using IndexOf and Remove, much like this:
vb.net Str = Str.Remove(0, Str.IndexOf("MyInfo"))
This can be quite heavy on the processor. So my question is it faster to look the informations using Regex or it would be about the same?

I've googled for a while now, but I can't seem to find it.
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.

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

This is what I thought might work but I'm not sure how to make it work for all the items instead of just the selected one..
If (ListBox1.Text.Contains(".")) Then ListBox1.Text = ListBox1.Text.Remove(0, ListBox1.Text.LastIndexOf(".") + 1)End If

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've come unstuck on a certain point. I am trying to find a way to compare two lists and output only lines which are unique. In other words, remove both occurrences of duplicate lines.I'm relatively inexperienced with VB.NET, but this is how far I have managed to come;
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim LinksList1, LinksList2 As String
LinksList1 = Replace(RichTextBox1.Text, "#vch", "") : LinksList2 = Replace(RichTextBox2.Text, "#vch", "")
[code]....
1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.
