Generate A List Of Random Integer With A Click Of The Button And Put The Results In A List Box Using .Net?
Nov 18, 2009
If I can generate a list of random integer with a click of the button and put the results in a list box using VB.Net but how do I randomly change several integer number generated by button 1 by clicking button 2? How I retain the results of button1 and change the results when clicking button2?I try before but the two button function code cannot relate to one another.

Below is the code that we have been working on. We have bolded the parts which we are unsure about - they are producing errors. (its near the bottom)The program is designed to generate a random hand of cards out of our list of them. This program is a smaller version of what we hope to have in the full one - ie. It tries to get a random hand of 3 cards out of a possible 5.
The part we are having errors with is getting the images to display on each of the 3 'picturebox' objects using a loop (so we don't have to type each picturebox individually).

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?

I know there has to be a simple way to do this but I'm not sure how the syntax would go. I need to generate a random number from 1 to 99. How do I do this? I have my attempt that failed below:
Private Sub LoadBoard()
Dim mynum As Integer = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99)
Storage.Slot1 = mynum(Int(Rnd() * 10 Mod 99))
End Sub

I wanted to generate random integer and put into array(9). My code is as follow:-
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Randomize()
Dim rand As New Random
[code]....
I wanted the results to be ans = 3412657846 But instead I get ten ans results. So that means the rand.Next generate ten integer to array(0) and so on.I just want one random integer in array(0) and so on....

I have 2 drop down lists and 1 submit button. It works such that after the user has selected values from BOTH the drop down lists, then the user will click a "Search" button. My problem is, after the user click the "Search" button, the second drop down list is no longer displayed with the selected value, instead it displayed a default value. May I know how can I make sure the selected value remain selected even after the user clicks the "Search" button on the page?
For your info, my coding goes as
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim strSelectedUsername As String

url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"
I realize the problem is the $AE$7 (the $A$3 is correct)

i've created a hangman game (Fully working) but since you can only "play" with one phrase (10 letters) it gets boring fast. Basic the current game works by on form load i define the slots (10 string which each hold a letter) and give them there letter. then the user type in a text box and if the textbox = any of the slots then the lbl repasenting that slots changes its text from "_" to the letter.
Anyway what I would like the button to do is when the user presses the start button a random number is generated. The program then looks into a textfile and based on which number is generated it takes a certain line (10 characters per line in a phrase) , moves them into the slots and the game starts. Is that possible to code or it too complicated. The textfile will be in the applications folder (words.txt).

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1
Const dcmPRICE_STRESS As Decimal = CDec(595.0)
Const dcmPRICE_TIME_MANAGMENT As Decimal = 695

I would like a function generate all of the k-combinations of elements from a List of n elements. Note that I am looking for combinations, not permutations, and that we need a solution for varying k (i.e., hard-coding the loops is a no-no).
I am looking for a solution that is a) elegant, and b) can be coded in VB10/.Net 4.0.
This means a) solutions requiring LINQ are ok, b) those using the C# "yield" command are not.
The order of the combinations is not important (i.e., lexicographical, Gray-code, what-have-you) and elegance is favored over performance, if the two are in conflict.
(The OCaml and C# solutions here would be perfect, if they could be coded in VB10.)

Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.

I am working on making a Windows based application within Visual Basic 2008 Express that could potentially be used for a music school as a project. This application is connected and bound to a Microsoft Access database. Within this application I have a form for adding a new appointment reservation. This form has a combo box that the user can select the lesson type (eg. "I want a piano lesson"). Upon being changed, a list box would be populated with the names of all instructors that have that selection as either their primary or secondary talent.So, my database is bound, the query is written (correctly...i hope), and I don't know how to 1) select the table column that I want displayed in the list box and 2) actually display the query results within the list box. Is this making sense? Probably not, bu
