Remove Empty Elements From Char Array?

View 6 RepliesRemove empty elements from char arrayI have this [code]...
View 6 RepliesI have a large one dimensional array that is called ArrayHold which is populated at runtime. I run a loop to scan through the array to find out which elements need to be removed based on a few parameters. This all works great, now I am left with two arrays. The original one and a new one which contains the locations of the elements to be removed.
Original Array: ("A")("B")("C")("D")("E")("F")("G")("H")
Second Array with index/count of elements that needs to be removed: ("0")("3")("5")("7")
End result should be preferably not in a new array but a "ReDim" of the original array:("B")("C")("E")("G")
What would be the simplest way to achieve this? I could run a loop to make all the elements that need to be removed "0" or ""? Would there be an easy way of resizing and array by dropping/removing all the white space or empty elements?
How to remove the Nothing elements from an array using a For or For Each loop? I have to display the array to a datagrid, but the Nothing elements of the shows up as zeros. This is the code I have so far for my button click event:

For m As Integer = 0 To carArray.Length - 1
If carArray(m).carid = txtDelete.Text Then
carArray(m) = Nothing
flag = True
found = m
End If

I'm using to code below to write and read an xml file. Writing works fine, but I get an error message on the"XMLReader.ReadEndElement()" line when an element is empty.'Element' is an invalid XmlNodeType. Line 4, position 6.XMLReader.IsEmptyElement is probably what I should use, but after reading the documentation, looking at an example and playing around with it for a while, I'm still not sure how to use it. No matter what I try, it still keeps showing an error on that line. This is the xml file.
<?xml version="1.0" encoding="utf-8"?>
<Data>
<Storage />
<Time>08:30</Time>

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?

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"
I have a List of a custom class (barData) that I need to remove elements form based on a date.
The bardata class holds data of stock price information.[cod]e...
Is there a way to do it without looping through each bar as I may have 2000 plus bars for each stock and may have 2000+ plus stocks to look at. It can be done by looping but it is slow.
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
View 1 RepliesIf I have code like this (C# or VB.Net does not matter)

I've come up with the following and it's partly working.
Public serial1, serial2, serial3, serial4, serial5 As SerialPort
Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)

Assume I have an array myArray1 = { A, B, C, D, E, F, ., T}I have another that contains a subset of the elements of myArray1 but where the order may vary
View 3 RepliesI feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?
I use the removeRange function to remove a couple elements from a list, but the Count of the list seems to be intact, so I assume it didn't work the way I expected it too.... so, how do you remove elements? I mean, reduce the list's Count value ultimately.
