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.

so I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.
View 4 RepliesI need to use the randomize function to generate a random number between 1 and 50 for lblNum1 and lblNum2, ensuring that lblNum1 is greater than lblNum2, otherwise the randomize function needs to run again for lblNum2. I need to ensure that the user has selected an option from the gbCalcType and cboGrade first, and then the randomize function should run when the user clicks the button named btnBeginGame. How do I do this? I have this so far that generates the random numbers when the btnBeginGame is clicked:

I 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'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've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesSay 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

3456 Lee
4567 John
There will be many more names but for this example you could use 3 or 4 etc..

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.

View 1 RepliesIs there a way to randomize the location of a button? I am making a "Button Game" that is a kind of guessing game.The user clicks one of three buttons on a form, and if it is the correct button, then the next form shows, which will be level 2. I pretty much got all of the code down. Now, though, when I debug and run the program, I noticed that everytime I reopened the the game, the buttons were in the same order.So, if the user plays the game once, closes the game, the buttons are still in the same order, and the user knows how to beat it! That kind of makes the game boring to play because the user knows where everything is.Is there a way to randomize the order of the buttons?
