Randomise Images No Repeats
Jan 7, 2012
I am a complete newbie at vb trying to design a quiz where the user will be presented randomised images to grade. I am at the stage of writing code to randomise image without repeating. Images are stored in imagelist (not sure if this is the best way to 100 images - I've read a few posts about limitations of imagelist) and are being randomly presented in picturebox. At the moment my code loops around continuously with repeats. However I would like it to present images randomly without repeating. Here's the randomise snippet of my code. Hellllppp! it loops round and I'm not sure about to remove images.

how can I 'randomise' the share values? (I am wanting to have some shares to have a higher risk than others, usually the ones with the higher value.)

I'm down to the final coding on one of my projects, when i notice that the backgroundworker behaved strange. For each time i run the backgroundworker, it repeated it self one more time, and the new time, it repeated one more time.
So, if i run the worker a third time, it would repeat it self 3 times.
First run: Runs one time
Second run: runs twice
Third run: run 3 times
And so on.
So, i'll post all the code from that form.
Here goes.

I dont have anything to handle it when its full but it never gets there. I need it to pick a random number from 1 to 60 that doesn't repeat but i keep getting a system.stackoverflowexception and it will repeat numbers.
num = RandomNumber.Next(usedcountries.Length - 1)
'TextBox1.Text = num
If first = True Then
usedcountries(y) = num[code]..............

I've seen a few other people ask this question and have tried the responses that they have had with no luck.
I am trying to use the randomize command to generate a truly random number. What I am doing is reading an access table to get the number of records, then seed the randomize statement with that number of records with the top range for a random number. I then use the number to select the record I want from that table via it's ID number. My code for doing that is working great.... except that it is always calling on the same record each time through the loop. Here is the code.

Here's the code:
'Determine and Display User-Selected Major Chord
If Me.tvChordExpressions.SelectedNode.Name = "NodeAMajor" Then
'display chords
Me.pbMain.Load("D:Visual Studio 2010ProjectsMusicaMusicaChordsMajorA.jpg")
'play A Major Chord
My.Computer.Audio.Play(Application.StartupPath & "Audio ChordsAMaj+10.wav")
End If
[Code]...
this works great, however the problem is that the audio file (A Major in this example) will repeat playing every 4-5 seconds. Question?...Why and How do I stop this?

I'm trying to shuffle a Euchre Deck and it works but I feel like I'm cheating. Is there a more concise way to randomize a list of numbers 1 - 24 and have no repeats? ex. 14, 3, 18, 23...
Dim Deck() As String = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
Dim A As New Random
Dim B As Integer = A.Next(0, 24)
Deck(B) = "9 of Clubs"

I am trying to write a program that gives a random number with out repeats the limit is 60 right now. I get a System.StackOverflowException error randomly sometimes it could be 5 numbers in it could be 50. also it will repeat some numbers. Ive been looking over it and it looks like it should work to me idk why its not.
BTNgen calls this sub.
Private Sub gen()
If y = usedcountries.Length - 1 Then
BTNgen.Enabled = False

I'm trying to make a Bulls and Cows type game, I was able to do it fairly easily with javaScript, but VB is killing me. I can get the array 5 slots long with random numbers, unfortunately they're all repeats. when I try getting no repeats I run into infinite loops, exponentially increasing array lengths, and just plain old arrays with 5 numbers randomly generated, but with repeats.
I'm trying to do this with loops, in JS I did it using regular expressions
Here's an example of my code.
Public Class Form1
Dim intRand(0) As Integer
Dim RandomClass As New Random

I'm wondering if anyone else has encountered this in visual studio 2008. I'm writing an asp.net app and when I run through debug it's jumping all over the place. It skips certain lines, at least it appears to, then it jumps to the bottom of the page and repeats the same line a few times then jumps to a separate sub I have in there. The weird thing, besides its behavior, is that it's not grabbing a piece of information that exists in one column but is grabbing another one. So anyone else encountered this? What's the fix.
To give a more detailed example it did this on the last debug. I started the breakpoint at line 40. It went to 43 with no problem then jumps to line 66, an end sub line, it then proceeds to go on to the private sub directly below it. That includes it going over the blank lines that would normally be skipped. It goes through the entire private sub line by line including a catch ex line but it displays no error. After hitting that line it immediately returns to line 46 of the sub that it already passed by the end sub line. It then goes down 2 more lines jumps back to the private sub it just left and repeats the end sub line 3 times, only the b at the end is highlighted when doing this not the whole line.

Beginning VB 2010, had a project that requires us to create a list box of 25 randomly generated 0s or 1s. Problem is when I put the loop in, it only repeats the same random number, not different one each loop. What am I doing wrong?This is the code I have so far...Code in Question:
'Declare new random object
Dim RandomGenerator As New Random
intRandomNumber = RandomGenerator.Next(0, 2)[code]......

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

I have a report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.
Code I have in report
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.

The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

I'm creating a form which is basically an image in a picture box that I use the graphics object to do drawstring's and drawimage's upon.I keep track of where I'm drawing these things so that I can click on them later and do various things (launch external apps - whatever).Is using a picturebox and the graphics object the best way to approach this.

I am making an that uses an external dll which should hold all the images used by the app. I know how to do this i.e. add images to resources or imagelist, then return them using a function which is referenced to. But, I have no idea how to tag the images so that I can obtain an idea of the images belonging to that category.
E.g. My dll has 100 pictures of houses. When the person looks for "white" I should be able to look through my tags for white houses as soon as possible. And at any point, if I wanted to, refer to the images programatically (that part shouldn't be a problem). So the only problem is tagging, what is the easiest/requires least amount of code to be written for?

I'm working on a little project and I'm having an issue with the amount of time it's taking to create a 100 x 100 grid of picture boxes. Currently what I'm doing is creating the picture boxes dynamically using a timer with a progress bar because of the fact it takes so long it will look to the user as if the program just froze up.The images don't need to actually be contained in picture boxes, but I do need to be able to call mouse events off of them. I tried using a tablelayoutpanel, but for some reason I can't find anything on google on how to target individual cells.
