I got the textbox and a listbox and a button, I can add names threw the textbox hit the button to add and it adds to the listbox, now I need to take the names from there and randomize them into 4 groups and make it into an array also, I just dont know how to take the names I entered and randomize them and put them into 4 different groups without repeating themselves, it is ok if three groups that have 5 and the fourth has 6. They just need to be randomized and put into 4 different groups,This is what I have, but I think its the wrong way to do this, to make the code work right atleast.[code]
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 1 RepliesI am creating a Map Rotation Randomizer for my Call of Duty clan, and I am having an issue with understanding how to randomize the text from the list and placing it into another textbox.
Here's what it looks like right now:
All textboxes are multi-line.
When I click a button for a game (CoD4, MW2, WaW), it places the map list into the left textbox like:
mp_bloc
mp_broadcast
mp_crossfire
etc.
When I click the button with ">>>", I want it to randomize that list and place it into the right textbox like:
map mp_bloc map mp_broadcast map mp_crossfire
Or if I click it again:
map mp_crossfire map mp_bloc map mp_broadcast
And so on. I think I need to create an array, but I've never worked with those before as I'm still new to learning programming. I'm not even sure what controls I need to put on the form for that, if it even requires any.
I have a USB device that is "seen" as a COM Port. It has eight channels, each require a single character to turn ON/OFF. It's a DLP-IO8 for reference. I have the COM port part working 100%.
1-8 turns ON each channel (12345678)
Q-I turns OFF each channel (QWERTYUI)
Truth table for device:
1 = Ch1 ON | Q = Ch1 OFF
2 = Ch2 ON | W = Ch2 OFF
3 = Ch3 ON | E = Ch3 OFF
[Code].....
a loop that I can still use the functions of the form (change speed or Stop loop).
a way to utilize Q-I to turn the channels OFF in random mode
I've been searching for a few days with little luck. I've tried Do Until, Do While loops and a few others.
I've only been coding for a few days now so go easy. Learning as I go. My form for reference
Ultimately I'm trying bring my PC Interface project up to date by going from a parallel port to USB.

I've got an array containing lots of "Color" and I want to change the order of this colors (random) but with a password: so another user can get the "original" (and correct) sequence of the array only with the right password. How can I do this in Visual Basic .NET or C# ? Do have I to use a particular encryption engine?
View 2 RepliesI am currently working on a personal project. I have the template for my program layed out and now just need help with some codes to go in it. I've looked for codes online to give me a better understanding but have had no luck so far. What I would like to do is to be able to "randomize" a line of characters with only capital letters and numbers 0-9. I need the overall length to be 14, but realistically 17. The displayed characters would be in this form. XXXX-XXXXXX-XXXX, so the dashes would have to fall into that area with all other characters being random. I want it to link from the 1 buton to the 1 textbox.

View 4 RepliesI'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'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.
i.e. Table Data
ID | Name
4345 Mike
3456 Lee
4567 John
There will be many more names but for this example you could use 3 or 4 etc..

View 2 RepliesI am making a random name generator. what I got is a large list of first names in listbox1 and a large list of last names in listbox2. when I hit a button, I am randomly pulling a name from both listboxes and putting them into 2 textboxes. for some reason they arent always random. I would say out of 50 names I will get 2 or 3 sets that are identical. why??keep in mind I probably have 400 first names and 200 last names. I should never get a duplicate! here is my

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.
