How To Show Random Images In Three PictureBoxes
Aug 26, 2009
I am writing a program that shows random images in three picture boxes. When I open the program the initial images are in the picture boxes. When I click stop, the program is supposed to select a random image out of five. in each picture box. However, when I click start the images go away and when I click stop, no images appear. There is also a message that is supposed to come up on the screen, which it does. I just can't get the images to show. I am using Visual Basic 2005.
My code is below:
Public
Class videoBonanzaForm
Private images() = {image1, image2, image3, image4, image5}
Private image1 As Image = Image.FromFile("sevenpounds.gif")
Private image2 As Image = Image.FromFile("push.gif")
[Code] ......

else

I am trying to generate random images from access database using hashset as it is said to be unique and there won't be any repeated images appearing. But, it doesn't seem to work. ow can i get it to work? By the way, i am very new to the concept of hashset.
Private Function GetImageFromByteArray(ByVal picData As Byte()) As Image

I wish to make a wallpaper changer that can select a random wallpaper from a given directory and sub directories. I'm not asking for code at this point, I'd like a reality check to see how hard this could be. I'm still quite a newbie at VB so I just wanna check if what I'm thinking process wise would work.The basic thing I'd like to do is have it pick one picture out of a given dir and sub dirs. Then set it as the wallpaper. I'd like it to be resized if larger than the desktops resolution to fit inside it, no stretching cropping or stuff.
That's the simple things I'd like it to do. Unfortunately I have dual monitors so it'd have to pick two wallpapers, resize each one independently, stick them together, and then set the wallpaper. I'd also like to make a kind of simple database which would have the name of each pic and two values with it. I'd like a value to mark if it's been used already which would be reset when all pictures have been used. The second would be a simple tag. This way i could have all car wallpapers listed as tag 1 and all non-car wallpapers listed as tag 2. Then I could chose whether to use all or only tagged wallpapers.

I am trying to setup a treeview control to display all drives and folders on the PC. So far I can display all drives and folders but the images will not show except rarely. I am using an imagelist with 4 images (index 0-3). The code below is used to load the drives in the treeview control. I have tried using every type of image possible from bmp to png and nothing. I have tried the Appllication.EnableVisualStyles() which I now know isn't needed in vs 2008. I am also having problems with a picturebox in another form that shows nothing but a shadow of the image. I suspect this may be a setting somewhere maybe in vs 2008 but am not able to find one.
Treeview
Dim drive As Integer = 0, dir As Integer = 0
For drive = 0 To oDrives.Length - 1

i'm making an app which uses a webbrowser control to show some offline (not cache) html pages like a slide show. let's say pages in a folder on the desktop etc when it came to testing the whole thing, i figured out that the images in the html are not visible on the webbrowser control. instead there is a space where the image should be, corresponding the actual image dimensions.and when i right click on this empty space where images should be, and click on properties, i see the image size given as -1 byte (minus 1 byte) and there is no image type.
however given any online url's to the same webbrowser control or opening the same html pages with the real internet explorer i got no problem and see the images.i've been googling for almost 10 hours for a solution without success, so any hints are welcome. used vb 2008, .net framework 3.5, ie 7.

Which of the VB controls is best suited to show images in a strip like fashion from an Image Array?I have an Image Array. I would like to display the images in the array to the end-user in a control.The control should should apear like a scrollabel list. I guess something like silverlight does.When the user sees and selects an image he/she wants to view, it is selected by clicking on the thumbnail and appears in a picturebox.
