View 1 RepliesFor my programm I am supposed to store the minimum points in a five-element, one dimensional integer array name points. And I need to store the grades in a five-element, one dimensional string array named grades. These arrays should be parallel arrays. I am supposed to code the display grades button click event procedure so that it declares both arrays. It also should search the points array for the number of points entered by the user, and then display the corresponding grade from the grades array.
Here is my code:
Option Explicit On
Option Strict On
Option Infer Off
Public Class Grades

In one of the vb6 form, we have a parent - child relation controls. The parent side consists of few radio buttons and the child side contains the control array elements. On click of each radio button, the control array elements are refreshed and populated with data related to the option selected. In the existing application, they have made use of "Load" and "Unload" methods for control array elements. The control array elements are created in the design time(which consists of labels, text boxes and button) and are all placed within a panel, which in turn is placed within 2 group boxes.But the problem comes when I have to unload these array elements.
The control array is created in the design time and the loading of each of these controls is based on certain conditions which is decided during run time.
1. Is there any alternatives to show/clear the control array elements other than control.Load(index)/control.Unload(index)?
2. Is there any way to check whether the controls are loaded or not.

I haven't used vb.net in about a year. I have a few arrays, the first holds a list of names. that list is used to load files into memory and then based off that file, another array is filled with my custom data type.
array of names is a file. it is not in memory unless it is being written to or read from. the second array is where all of my data is stored Dim fs As New FileStream("EmpVec.vec", FileMode.OpenOrCreate)'EmpVec.vec" is the file that stores all of the names Dim reader As New StreamReader(fs)while not(reader.EndOfStream)'code that is used to load and fill my array'it sees the name, searches for a file with the same name, then loads data from that file into my vector and memory'as i do this, i fill a list box with the name, and another string object (name & vbtab & string)end while. so that is when i populate my arrays what i would like figuring out is how to remove objects from my arrays here is what i got Dim index As Integer = Me.lstEmpList.SelectedIndex EmpVec(index) = Nothing 'EmpVec is the array that stores all of my custom data types
Me.lstEmpList.Items.RemoveAt(index)''this will remove the data from the array but I also save all the contents in the array to the EmpVec File'so when it hits the empty element, it crashes because there is no data'i would basically like to resize it

Say I have a two dimensional array
[0] [1] [2]
[3] [4] [5]
[6] [7] [8]
Now suppose I want to get the position of the number 6
I know with a one-dimensional array i can use Array.indexOf() but what would my options be with 2-dimensional arrays?
Dim strArray() As String = {"test1", "test2", "test3"}
strArray.SetValue("", 1)
Console.WriteLine(strArray.Length)
Console.ReadKey()
This still leaves me with an empty array value, how can I just delete it or can't I? Do I have to use an arraylist and if so how do I convert an array into an arraylist?
