VS 2010 Draw Rectangle (random Times, Random Location)?
Nov 26, 2011
I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees()
NumberOfTrees = Int(Rnd() * 10) + 15
For i = 0 To NumberOfTrees - 1
bmap.MakeTransparent(Color.Fuchsia)
[code].....

The class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.

I've made an image viewer which opens a random image from a specified folder, but the random number is not that random at all... I've already used Randomize(), but without result.

I have created a form in which it watches a specified path for excel file changes - this part is on load.
[Code]...
This is supposed to delete any temp file that gets through. Then, when it finds an excel file, it will try to open it. I noticed the sub kept launching when I opened the excel file, so just another check to make it safe. the two variables filearray1 and filearraypath2 are public - filearray1 is an array list with full excel paths (another thread loops through the array and does the operations of the excel file) and filearraypath2 makes sure that the same excel file won't be added twice in a row.
Now, this works really well, but for some reason, at some point, the addfile sub won't kick off, even if excel files are changed, created, deleted, anything. I set a breakpoint on the first 'if' line of the addfile sub, opened an excel file and made changes, or created a new one, and let the program run for 10 minutes and the breakpoint never hit.

I need a random number of 6 (1 ,6), and to loop it 3 times. I tried this but it gives me error for - if myRandom.next(1,6) Then:
Dim myRandom As Random()
For i As Integer = 1, 3
If myRandom.next(1, 6) Then
End If
Next
Also I need to know the code for putting a picture into a picture box.

I am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........

I am a grade 11 student in high school and am struggling with a project in my computer programing class. in the project we are to create a mario game, where you have 2 pictureboxes (the player and the enemy) one picturebox, the player, is moved using the keypad, the goomba isn't moved at all. the object of the game is to 'kill' as many goombas as quick as possible. I need to make the game so that if the boundries of the player intersect witht he boundries of the goomba, the goomba will move to a random location.
I can't get the goomba to move to a random location, here is my code. I highlited and bolded the part of the code that I am having the prolem with.

Dim intLocation As Integer
Dim intCounter As Integer

I'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]

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]......

I have a picture box and I tell it to appear on a random location on another specified larger picture box.
here's my code:
Code:
Sub P2_AppleMove()
Dim P2ax As Integer = CInt(Int((P2Foodarea.Width * Rnd()))) ' sets the random area of the food
[Code]....
P2foodarea is a large picture box I created. I only want the apple to spawn on P2Foodarea, atm, it spawns on P1Foodarea which is very weird. P1foodarea is a whole other picture box. I even made new variables as you can see P2ax and P2ay, but it still doesn't spawn on P2Foodarea. I have even tried recreating a new picture box for P2foodarea

I'm trying to make a Form pop up at an random place (given in a textbox). Here is my code so far:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Form2.Location = Textbox1.text
Form2.Visible = True End Sub
Yes i know it doesn't work. What I really need to know is how to make the txt understandable for the system.drawing.point.

I'm currently working on a screenshot program, much like Gyazo and I've come across a problem.
[code]...
Now, it draws perfectly when I drag left to down (vice versa), but when I try and drag the opposite way (this is when I get negative x and y values), it doesn't seem to draw the rectangle.I've tried fixing it but with no luck at all, it just messes it up :c

I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.

I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times

Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
