Getting The Index Of The Largest Integer In An Array?
May 24, 2011
I have an array of integers and I need to know the index of the largest number (not the actual value, just the index of whichever is highest).
However, if one or more indexes "tie" for the highest value, I need to have all of the indexes that share that high value.
I assume this function would need to return an array (since it could be one or more indexes), but I am not totally sure how to go about getting the more efficient solution.
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 [Code] .....
i'm having problems creating a simple button for a programme which finds the largest word in an array and puts it into a textbox. I've done most of the coding (I hope) was wondering if somebody could help me actually with the code that finds the largest text in the array as I am struggling the most with that.
Private Sub btnLongName_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLongName.Click Dim LongName As String Dim LengthOfLongestName As Integer
[wink]You'll notice i dim'd n as integer = 0...[/wink] hehe I need a bit of advice on how to find the largest number stored as data in an array. For example vote(0) = 6, and vote(3) = 12, and lets assume all the other vote(n) are less. How do I pick out the big one?
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.

The only issue i have is to get the smallest number to show up.. mine just keeps showing "Zero".
I want to find which of the 64 elements has the highest number and which of the 64 elements has the lowest number?Is there a new command in vb10 to do this quick with little code?

(I am not sure how to display line numbers in my code on VB2010, please if you know tell me and I will edit the post)
I create an array of this and load different distances into the ProjectileDistance property of the array. My question is this: How do i sort this array from smallest to largest value of ProjectileDistance?
Trying to input a high setpoint, low setpoint, a % load, and number of compressors, then calculate the temp that all compressors are off. Then build a datagridview with the staging of compressors from all off to all on for each compressor up to 10 compressors.I am trying to insert headers from 1 to 10 compressors (Variable) with the text "Comp1", "Comp2", etc....Two rows with header. I am trying to use an array with index number to insert the text, but that is where my problem happens."Index was out of range".Here is my code

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?

this is for a BINGO game final project that I already turned in but this just bugged me that I could not get the sorting figured out. I am trying to get this to sort the random numbers in to columns under the correct letters but I keep getting the error Operator '>=' is not defined for types '1-dimensional array of Integer' and 'Integer' under the line:
I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .
I need to develop a function called SetComboBox that accepts the category(ies) in the ComboBox as a string and returns an integer indicating the index position of the category in the ComboBox. The function is supposed to set the category in the ComboBox Selected Index property to match the string category stored in a database for an inventory item.
I have a program that calculates values of a function, say f, with respect to another variable, say L.I have an array of f(L), for L going from 0 to a given integer value, say t-1 in steps of a value i.I need to export the values of this function to an Excel spreadsheet in a given column, and to do this, I would like to re-index the function f, since i is much less than one, and so the following loop I use (see below) won't work:
For L = 0 To t - 1 Step i Sheet.Cells(L, 1) = L Sheet.Cells(L + 1, 2) = f(L) Next L
The first code in the loop will essentially load the values of L itself, at which the function is defined and calculated, and the next line will load the values of the function at each value of L.Since the indexes of the row and columns in an excel spreadsheet only go in steps of 1, I need to convert the indexes of the function, or the indexes to which L is loaded, so that it would be scaled so that the first entry corresponds to L=0, but the next is L=i, but loaded into row number 2, etc.
Per this UserControl that can be added to a blank form, I would like to use the HorizUnits array below to map custom grid x coordinate from a mouse x position.For a given input value 13, what syntax would I use to obtain a value of 2 where 13 lies between Value 10 and 16 for which 2 (Name) would be the custom grid's displayed coordinate position?
i have an array contains a-z.Then i have a textbox and when click on the button, it will replace the text inside the textbox to the index number of the array.Example, from "abc" will become "0 1 2" The code below do the job.how to do so that i can replace the text inside the textbox from "0 1 2" back to "abc" based on the array?

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.
