I have like a collection of numbers like in a hashtable for instance
Code:key / val----+------ 1 / 2349 2 / 939 3 / 49444 4 / 93 5 / 114
How would I go about checking which one of those keys holds the biggest value?
Code:For Each dict As DictionaryEntry In htNumbers
'What?
MsgBox(dict.Value.ToString)
Next
I'm working on a project which generates numbers. When those numbers have been generated I would like to arrange them from smallest to biggest. Let's say 6 22 8 12 15 2 is generated. Then i want it to be re arranged to 2 6 8 12 15 22
This is the code I'm using:
PHP
Private Sub btnRandomClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSlumpa.Click
Dim random As New Random

Suppose I have 5 Integers(A, B, C, D, and E) and 5 Textboxes. When the program run, the user is going to input 5 numbers to those 5 textboxes. When a button is pressed, a label will show up and write the textbox number with the biggest number.
View 1 RepliesSo how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:

I have this:
dim nmbToCheck as Double = 15.22
dim nmb1 as Double = 12
dim nmb2 as double = 18
How do I check wheter nmbToCheck is between nmb1 and nmb2? I know I could use < and >, but the problem is that I won't be knowing which of the numbers will be smaller, and which will be larger, and it seems like a lot of code to write for such a small issue. There must be some sort of nmbToCheck.IsBetween(nmb1, nmb2) type solution to this, right?
