Separating Delimited Variable Into Array Elements In .NET?
Mar 5, 2012
I long variable in vb.net which contains the following information,
Dim g As String = "$C:Program FilesCavaj Java Decompilercavaj.exe$C:UsersYoosufAppDataLocalGoogleChromeApplicationchrome.exe$C:Program FilesDVD Makerdvdmaker.exe$C:Program FilesAdobeAdobe Photoshop CS2ImageReady.exe$C:Program FilesJavajre6injavaws.exe$"
The $ symbol is used as a delimiter to separate each item from the other. I need to add the exe file name at the end of each path to a listbox. However the initial process of retrieving the variable to individual array elements is not working properly.
Dim strArr() As String = g.Split("$") 'This variable is empty
For count = 0 To strArr.Length - 1
Dim arr As String = strArr(count).Split("")
[code]....

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)
Next

I 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 have a one-dimensional array that has one number per element. I also have a variable number, var. I need to take the number of elements from the first array that equals the var and put it into a second array with commas between the numbers. I would also like to have a title element in the second array. [Code]

I have a text file with for example this data in it :
"19 Mar 2010","6:00","16:00","10","1","9","6.61","59.49"
"20 Mar 2010","9:45","19:15","10","1","9","6.61","69.89"
"21 Mar 2010","9:00","17:00","8","1","8","6.61","99.32"
I used " , " to delimit individual pieces of data and " " to denote end of line.I'd like to be able to split the files into lines and assign each line to an array then split each of those array strings into the comma " , " delimited data and feed each piece of data into another array ready for writing to a datagridview.
I've spent a while trying to get Split() to work but I get errors regarding converting strings to one-dimensional arrays Also the Split() method asks for a "ParamArray" but I haven't been able to find examples of other people providing them on the net any idea what those are about?

I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:
21,Z920081
22,Z920082
59,Z930023
120,Z930027
I'm trying to input this into an array and then a combo box using:
dim item as integer
dim array() as string
dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.

I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.

Do List's hold the instances of a variable element or just the pointer to the the variable element? My application uses a list of elements, which can be re-ordered at any time, but I need to maintain another list of pointers to those elements, so that the element pointers can be used to access any element irrespective of their order in the main list? the difference between a pointer or a variable in the contect of list elements?

How would you code this so that it adds up the first column, and then the second column?
Dim intSales(,) As Integer = {{100000, 150000}, _
{90000, 120000}, _
{75000, 210000}, _

I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-
[Code]...
Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.

Now I'm VERY new at the reading in a text file and storing into arrays thing and tried for hours last night to figure this out, googling and every possible way of writing the code. However, I don't know what to try next and I'm getting more confused by the minute. I have a text file which I load into my program. This data is stored into 6 arrays, each of which has data that comes from either a combobox, date or text field. What I'm trying to do is to find the count of items in each index of the array.

In this case I'm trying to create a number analysis app. I'm required to declare an array and get the data for the array using ten text boxes. Why, because my instructor said so.
My problem is my event is returning zero. Therefore I believe my code is somehow flawed.
My approach is to create functions that calculate the required metrics. I have only tried to code one function to date. If I can get help making one function work, I will be able to do the others .
Public Class Form1
Dim decScore0, decScore1, decScore2, decScore3, decScore4 As Decimal
Dim decScore5, decScore6, decScore7, decScore8, decScore9 As Decimal

I have a class I am working on for a program I am writing while I am stuck at hospital 3x a week and was wondering. If my class has a Reset function that sets the count variable to 0, can I then say that the Data array is equal to "nothing" and wipe all the data that was in it?
Below is the class structure so far:
Private Count As Integer = 0
Private Data() As Integer
Public Sub Add(ByVal value As Integer)
Count = Count + 1

For example, I have an integer array called sec1() that has 71 elements.
I tried:
vb sec1(1 - 71) += 1 But when I run the program, it gives me an error. Not a red-underline error, some other error that doesn't stop the program from compiling but stops it from running. Is there a way for me to modify all of the element of my array at once? just out of curiosity will the same method work for string arrays?

I have an array x in size of objects (between 1 and 100) and I want to increase the size to 101 ... I've resized the array and that adds the objects but unfortunatly (not suprising) the added items have not been initialised, do I've reverted to using a do while loop and adding the elements indiviually, but looking at the code around it where addrange is used extensivily, I was just wondering if that was a neat vb.net way of doing the same thing
Bit of a learning question, just looking for neat ways to do the same thing
