Find Smallest Item In An Integer Array
Dec 1, 2010
I have an array called linedistancearray.I am now trying to find the smallest integer in that array and store it another variable called mindistance..The following is my initial idea: I sort the array and then pick the integer with index 0. Array.Sort(linedistancearray)However what I get is the first item being a 0 not the smallest integer value in the array I need. HOWEVER if I choose the index 1 it works.So what I was thinking was a way to remove all 0s in the array. I am not concerned about the order of the items at all all I am looking for is the smallest integer in the array.

I'm using Streamwriter/Streamreader for the first time in this project and keep getting an "Argument out of Range Exception was unhandled" error.It says "length cannot be less than zero. Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value?

I'm making a function that searchs an array of Customers and returns a Customer object by a given ID.
I'm trying to do so with Lambda Expressions,and this is what I have so far:
Public Shared Function FindCustomer(ByVal ID As Integer) As cCustomer
Dim customer as New cCustomer = _ _
Array.Find(arrCustomers, Function(c as cCustomer) c.ID = ID)
Return customer
End Function

I have two text boxes on my form. text box 1 allows a user to type in a number (decimal) and text box 2 will display the smallest number typed in so far. The idea is to find the smallest number typed in by the user in text box 1, by using the Math.min method to compare each number typed in by the user to a variable that contains the smallest number to the point. Then replace the variable value with the smaller of the two numbers. To make it work for the first number. I have to initialize the variable to 99999. (no if else statements should be used).

I retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?

Getting largest and smallest number from an array and placing in 2 dif Posted 02 November 2010 - 05:34 PM I have the code written for everything except when I try to display the highest and smallest numbers from the array into a label it display 0 for both the smallest and highest number.Question: Create an application that lets the user enter 10 values into an array. The application should display the largest and smallest values stored in the array.
*The form is a list box with 2 labels and a button to retrieve the 10 numbers and put them in the list box then the other button puts the highest and lowest number in the 2 labels
Note: Place them in 2 diff sub-routines.

Option Explicit On

What I am trying to do is fill an array from the largest index to the smallest index -- with the desired effect of reversing the values in the array. I have been looking at doing it with 2 for...next loops and I thought I had it, but I don't. As the reversed array is empty at the end of the 2 for...next loops here is code that I have been playing around with.
Dim myIntArray() As Integer
ReDim Preserve myIntArray(4)
myIntArray(0) = 0
myIntArray(1) = 1
myIntArray(2) = 2

ive got some simple problem i cant understand how to solve.
str(1) is an array and integer(or double, tried both)
a(1) is an array and integer (or double, tried both)
a(1) = a(1) + 1
Label1.Text = str(1) + a
the big part is where i get: operator '+' is not defined for types 'integer' and '1-dimensional array of integer'.why do i get that message and what does it mean? how do i make the code do what i want?

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing
item = item.NextItem

I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.
Shared Function CompareArray(ByVal FirstArray() As Object, ByVal SecondArray() As Object, Optional ByRef ErrorMessage As String = "") As Boolean
Dim IntArrayOne() As Integer = {1,2,3,4,5} Dim IntArrayTwo() As Integer = {1,2,3,5,6} Dim IsSame As Boolean = False IsSame = CompareArray(IntArrayOne(), IntArrayTwo())

I am having problems removing an item from a List(Of Integer). I see you can remove it by doing a remove with the index, but I assume you can do some type of function where you provide the value that you want to remove and it removes it. I found it on the List(Of String), but not Integer.

I'm having trouble with this specific code and on arrays in general. This is what I am asked to do: "In this exercise, code an application that displays the number of students earning a specific score. Declare a 20-element, one-dimensional integer array named intScores with the following 20 numbers assigned to the array: (88, 72, 99, 20, 66, 95, 99, 100, 72, 88, 78, 45, 57, 89, 85, 78, 75, 88, 72, and 88). Code the procedure so that the user can enter a score from 0 to 100. Then the procedure should display using a message box the number of students who've earned that score."
First off, I do not know what I'm doing wrong with my array.. it says there's an error in line 31 saying "variable intSubscript hides a variable in an enclosing block" but I don't know what that means. And lastly, once that is sorted out, I don't know how to code a message box to appear saying how many students have received that score.
