View 5 RepliesI cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

View 2 RepliesI am trying to shuffle an array of numbers it is randomizing but the numbers are been repeated is not what I need., I need the array to be shuffled but keeping the same numbers.For example if I do a first shuffle numbers may look like this in random order
2,4,5,1,3
Next shuffle maybe
3,5,4,2,1 and so on
But my problem is it repeating e.g. like this.
0,3,3,4,5 or 4,5,5,3,3

I want to shuffle the numbers in each column of _bingoNums(,)I've included the code I've tried thus far that dosen't work.
Dim _bingoNums(,) As Integer = {{1, 16, 31, 46, 61}, _
{2, 17, 32, 47, 62}, _
{3, 18, 33, 48, 63}, _

i am trying to find out how it shuffles the number 1, 2, 3 and 4 without repeating the same number within the series. So far, I think that "i" begins as 1 and RN is a randomized number between 1 and 4. The do while loop checks if "i" is the same as RN and spits out the flag as true or false. Then "i" is increased 1 at a time and so does the number of elements in the array. I believe that the array a(4) and the for loop does something that "remembers" the same numerical value not to be repeated. I'm not sure exactly what the for loop does and how the flag make this thing work.
Lets say, a case where i=1 and the RN=3, the flag becomes false. Therefore, a(1)=3. Then, i increments by 1 and a(j) becomes a(2), which puts out the values 1 and 2. Since both numbers are flag=false, it increments again. Because a(i) = RN, a(2) becomes = 3. How can this be? It has a(1) equal to 3 and a(2) also equal to 3. Each array is supposed to have NON-OVERLAPPING numbers.
The result of doing shuffle() is a random set of numbers that don't overlap:
1234, 1243, 1342, 1324, 2341, 3412, 4321, 3214, and so on.
but never 1111, 1112, 3333 or 3242.
To find out how exactly it works, I tried to delete some lines, tweak the numbers. The result of that is either numbers change to repeats, all zeros or a logical error. The following is the code placed in the module and can be used for other forms and in this case it is used for the labels in form1 windows form:
Sub Shuffle()
Dim a(4), i, j, RN As Integer
Dim flag As Boolean

i created a media player in vb.net. i have a listbox as playlist. My problem is i have picturebox1 in which if i have to click shuffle the items in the playlist (listbox) will shuffle songs. Also, the playlist must automatically play songs.
View 5 RepliesI have 1-10 audio files that were selected by the user using an "openFileDialog" (with a button and textbox for each). Now, I want it to play all of the files that they selected in a random order when the user clicks "Button12." After all the files have been played, I want it to start over and play all of them in a random order again. I don't want it to stop until the user clicks "Button13." When the user clicks "Button 12" again, it should start playing them in a random order again.
View 4 RepliesI have handed this assignment in and it works albeit not in the most elegant way. I am taking my second programming class ever and I would love for some feedback and answers to a few questions i have. First, what would be a better way to display the correct image to the corresponding card. Using all those if statements seems ridiculous, but i cant see a way around having card 1 possibly equal each value from every suit, card 2 equal each value from every suit, etc.
Second, my professor wants us to be able to record the seed value so that we could then plug it back in and return the hand that was shown when it was created. i have done this but I am a bit confused. The seed shows up as a value from 0-999, but when you use the combination formula to figure the total possible amount of hands you get over 2.5 million. Since i only have 1000 seed values does that mean that multiple hands might share the same seed value or does that number (0-999) mean something different eache time? Sorry if my explaination seems confusing.
Third, I am always looking for advice on better ways to do things. If anyone has free time and would like to offer constructive critisism I would be grateful.Below is the code. I only left in picturebox display for 1 suit so as to shorten the total amount shown. I also removed code for other buttons and stuff.
Public Class Form1
Private Sub btnShuffle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShuffle.Click

Basically my program has a "shuffle" music feature:
vb For i = 0 To 26 num = randomObject.Next(0, 27) My.Computer.Audio.Play("C:UsersMcturtlesMusicSongs" & num & ".wav", AudioPlayMode.BackgroundLoop) Next
Which selects a random number 0 - 26 and selects the corresponding song.
And a straight play feature:
vb Dim counter As Integer Do Until counter > 26 My.Computer.Audio.Play("C:usersmcturtlesmusicsongs" & counter & ".wav", AudioPlayMode.WaitToComplete) counter += 1 Loop
All of these activated by a button(separate for each)
When I click one, it makes the program stop responding. I'm pretty sure it is the .WaitToComplete mode, but I can't find a way to make it continuously play without it. If you can find my error. Also if you could tell me a way to make the shuffle never play the same song twice, that would be awesome as well.
Not sure if this is the right thread place or not.And I've been designing an Mp3 player. I've ran across several things that I would love to know how to fix.
1. It won't play the next song when one ends.
2. Click and drag media files into the playlist.
3. Shuffle button would be awesome.
4. Repeat button.
5. I have a pause button, but it dont pickup where it paused...
If you could get the repeat playlist and shuffle into a checkbox form.[code...]

I'm confused on when I should use the Randomize() function.It's my understanding that will give a new seed to the random based on the system clock, so should I therefore call it each time before generating a random number?I seem to recall reading once that it should only be used one time (like in the form load event), thus my confusion.

I have previously been told that I should always use Randomize() before I use Rnd() in a vb.net application, yet it always seems to work fine without it. What does adding Randomize() do for me in this case? It doesnt appear to affect my application in the least.

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.
