View 8 Replieshow to have the code randomly pick a memory location in an Array without having it filled, perferably in VB.NET Thinking of the logic, I was thinking
Dim random As Random
Dim tic(2, 2) As String
random.Next(tic(2,2))
Would putting the array as a parameter would randomly pick a memory location in an array?
I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer

Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

View 3 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
I am writing a class and room scheduling program, and would like to use an arraylist that will contain structures. The structure has a couple of arrays in it for when the class meets, and I am having difficulties figuring out the correct syntax to declare the array in the structure. Additionally, in the syntax to access the array. For instance, say I want the MeetingDays to be T, F, T, F, F, F, F; the Meeting Times to be "8:00AM", "", "8:00AM". "", "", "", "", ""; and the Duration to be 75, 0, 75, 0, 0, 0, 0

View 8 RepliesI have a site that dynamically creates two arrays of Lat/Long values based on the stores that the currently logged in user can see. If the user can only see one location then I get an error about array length needing to be a finite integer. When I look at the source I see var ls = new Array(45.056124);is being created on the page dynamically which is what I'm expecting. Except I think it is treating it as if I am trying to set the length of the array instead of set the first element to that value.How do I go about creating an array using the ClientScript.RegisterArray Declarationfunction to hold a single double value using vb.net?
