I want to get the n highest values from an integer array that has n or more elements. This can obviously done by sorting an slicing the array, but I'm wondering if there is a more efficient way to do this, since sorting a whole array would be quite ridiculous when for example only the top 2 elements of an array with length 4200 are asked for.

I'm working with a zedgraph bar chart and displaying only certain values from a dataset. I have a dataset with 912 records. One field is called "DeviceName" and one is called "TimesOffline". I am able to bind the chart to the dataset, but it wants to plot all 912 records. What I need is to somehow sort the dataset to retrieve the top 10% (or something) devices with the highest number of times offline.

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

View 4 RepliesI am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10

MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

I have a text box that a user can enter integer values. When the user clicks the button, I want the value to be stored in an array. It works for the first value, but when the user enters the second value and clicks the button, the first value then becomes the index number of the element that stores the value, which is bigger than the array. I don't understand why the array index isn't incrementing by 1, and why/how the user entered value is assigned to "number".
For example:
100 -> click -> array(0) = 100 'Correct
200 -> click -> array(100) 'Out of bounds
