I am using Visual Basic 2008.I am trying to code a simple "show and hide" game where pictures are generated behind a buttonThese pictures need to be generated randomly from my resources. i have got as far as declaring the random number, but am having problems with using a image as avairible which can then be used in a picture box. i have tried "image" but i am having no luck!

View 5 RepliesI'm working with a random number that generates a price for a house between 1 and 100 dollars (obviously very realistic).
Dim Housecost As Integer = (Int((100 * Rnd()) + 1))
My problem is that I put that number in the public class which does generate the number but only once. But I need the number to be re-generated every time a button is clicked. Now I would put this code snippet in the buttons Sub but there are 3 other subs in the code that call for that randomly generated number and the only way that I know of that allows all the subs to read this random number is to put it in the public class. So how do I put the number in a place where all Subs can read it and can be called to re-generate when needed?
How long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -
loop
stopwatch stop
display elapsed time

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

I'm working on creating a very simple dice game for class (not for gambling purposes). The users has already entered their total amount of money, and are are able to wager for every round. We were supplied with 6 different picture files to represent the 6 sides of the dice. It will be located in the C:\Temp folder, and after the user clicks a play button, the form (frmDice) will appear, which has two pictureboxes(pbDice1 & pbDice2) located on it.

View 7 RepliesI am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?
I have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.

I am currently working on a project on Microsoft Visual Basic 2008 Express Edition, in which I need to move an image across the form from one end to the other without moving it in a straight line. I want to try and randomize the image while it moves in a general direction, but I am not sure how. I also am trying to get four images to do this, from top to bottom, bottom up, left to right, and right to left.

View 3 RepliesThe 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...

View 6 Repliesi'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
I'm storing images in a List Of Image. When I want to clear/remove all the images it contains should I dispose & set each item to nothing before using .Clear? Or can you just call .Clear? I'm doing it like this for now...

For i As Integer = 0 to images.Count - 1
images(i).Dispose()
images(i) = Nothing

I have two (actually many) .png images in my application. Both have transparent areas here and there.I want, in my application, to take both images, combine them, and display the result in a picture box. Later I want to save the result through a button.So far I managed to find the two images and combine them, but it seems the transparency thing won't work. I mean, if you put one image over another, only the top image is visible as the result because, apparently, the image's background is a plain white box. Which is not. Here is a bit of my code:
Dim Result As New Bitmap(96, 128)
Dim g As Graphics = Graphics.FromImage(Result)
Dim Name As String[code]....
resourcesPath is the path to my resources folder. Bases is a folder in it. And Name is the image's name.
