Randomise Images In A Picturebox With No Repeats
Jan 6, 2012
I am trying to design a quiz where the user will be presented randomised images to grade. I am at the stage of writing code to randomise image without repeating.
Images are stored in imagelist (not sure if this is the best way to 100 images) and are being randomly presented in picturebox. At the moment my code loops around
continuously with repeats. However I would like it to present images
randomly without repeating. Here's the randomise snippet of my code.[code...]

I am a complete newbie at vb trying to design a quiz where the user will be presented randomised images to grade. I am at the stage of writing code to randomise image without repeating. Images are stored in imagelist (not sure if this is the best way to 100 images - I've read a few posts about limitations of imagelist) and are being randomly presented in picturebox. At the moment my code loops around continuously with repeats. However I would like it to present images randomly without repeating. Here's the randomise snippet of my code. Hellllppp! it loops round and I'm not sure about to remove images.

My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83)
Dim screenGrab As New Bitmap(154, 83)
Dim blank As New Bitmap(100, 300)

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
For intX

In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

how can I 'randomise' the share values? (I am wanting to have some shares to have a higher risk than others, usually the ones with the higher value.)

I want to be able to click a picturebox with an image and then load 3 other pictureboxes with images and then be able to click one of those 3 images and have it show in a bigger picturebox. How would I go about doing this? If its to confusing I will attach an example project I put together.

The title is simple and to the point: I have two images, same dimensions that I want one to fade in over the other. How do I do this without locking up the GUI?

I have made a screensaver in VB.NET. I am running into some roadblocks in the code though. The idea first was to have a ball bounce across my screens. It then evolved into spawning new balls that bounce across the screen. I then added collision detection so they would bounce off each other. Here is the problem that came up:
When said balls overlap each other, you can easily distinguish the edges of the picturebox that holds the images. I have made the background of the picturebox transparent, made the bitmap with a magenta background and made magenta transparent (for the image), but I can still see the picturebox edges when they overlap. It seems the transparency is not only making the background transparent, but giving it X-RAY vision to display not the visible area behind it, but the root background color of the form. here is a sample of the code which makes the transparencies.
Private Sub frmscr_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim bmp As Bitmap = My.Resources._smiley_face_image
Dim clr As Color = Color.FromArgb(255, 0, 128)
bmp.MakeTransparent(clr)
[code].....
I also tried to see if changing the image from background to foreground would help...no such luck.

I have a pictureBox on my form along with two buttons (Back and Forward) but I can not find a viable method of doing what I wish to do: Scrolling through images in a folder like the default Windows Picture Viewer does with Arrow Keys.Is there an efficient way to do this?
I'm using Visual Basic .NET with Visual Studio 2010, if that matters.

I'm trying to accomplish is having a 20x20 pixel image show up multiple times as determined by the grid selected. To keep things simple, what I'm trying to do is create a 9x9 grid of a image onto a form. I'm assuming that a picture box is the way to go, but don't know how to make that happen or if it's even possible.
So it would go something like this:
2D array already assigned:
Sub ShowGrid()
For rw As Short = 0 To 8
[Code].....
But instead of using a text box with values, I want to show a grid of a small image file, like cup.png which is 20x20 pixels or whatever, so what would show up on the form in this case would be a 9x9 grid of the image file over and over to create a grid.
Then the next step I hope to accomplish is to have that 20x20 square picture hold the grid(x,y) value for a mouse click. So if the image at grid(3,5) is clicked, it will give me that value, 3-5.

I would like to have a series of images displayed sequentially in a picturebox (every 10th of a second). I captured the images (image0, image1, etc) and placed them in a temp folder every 10th of a second.
I tried the following simple code, but I can only see the last image being displayed in the picture box.[code]...

I am trying to use GDI+ to merge two PNG's with transparency that I have stored in an ImageList, and then show this in a PictureBox. My PictureBox size, first image size, and second image size are all the same. I thought this would be simple but the following code does not work and I am not sure why. I have searched but I could not find any code snippets specifically dealing with PictureBoxes.
[code]...
At the moment when I click the button I see the PictureBox flicker with the image for a splitsecond.

I have written an application in which, among other things, there is a picture browser, allowing the user to load and look at pictures (jpeg-type). So I thought it would be nice if they could print their nice pictures too. And here is where all my problems started. I've tried almost all the code examples given to me, but none works. Isn't that strange?
I want:
a) The user will click the print button and the print dialogue will appear and thus enable him or her to choose wich printer to use
b) When the choice is made, click OK or PRINT or WHATEVER and the picture/photo will appear on a piece of paper which they can frame and hang on the wall or where ever
Yes I'm sounding sarcastic, and that is because I'm tired from lack of sleep, trying to make this happen. And I only have a few days to complete everything. To make it worse I haven't even started on the part where they are able to print text from textboxes on a form... Oh My God. for some reason I though printing something from an application would be the easy task when it comes to programming in VB. I was obviously wrong. It happens from time to time.
