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 have windows 7 background setup as a slideshow to change picture every 30 min. But when i use SystemParametersInfo in my program to set the wallpaper so i can see how it looks on screen, the wallpaper no long change like a slideshow. How can i display an image in the background but keep the current desktop background setting unchanged so that it will stay a slideshow on the location it was set?
iv been making a automatic wallpaper changer useing the timer, listbox, and picturebox , it works, untill i minimize it then it stops changeing the background, but when i maximize it it has actually moved down the listbox of pictures each time so the timer must be working when minimized, just it doesnt change the wallpaper when its maximized it always works,
I have a "menubar" of sorts on my aspx page (jsddm). The items appear when the mouse hovers over the top-level menu item, and disappear when the mouse leaves. When I hit F5 on my virtual machine it works great (my vm is running Win 2003 server and using IE 8.0.6001.18702, also runs VS2008).However, when I publish it (hosted in IIS on the same VM) and try to view it from my regular machine (Win 7 with IE 8.0.7600.16385) the little buggers won't work properly.
What would be the way to display random images in a picture box?When form opens, picture box displays random images, one after another (animated).When person pressed stop button, images stop randomly.
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] ......
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 If picData Is Nothing Then Return Nothing
Heres the code im using to select images from a directory , i also have a timer delay between each image , but my problem is when i start my app , it start by selectind image 1 (Images are numbered 1-15) but i want to select the images randomly ?
Private Declare Auto Function SystemParametersInfo Lib "user32.dll" (ByVal uAction As Integer, ByVal uParam As Integer, ByVal lpvParam As String, ByVal fuWinIni As Integer) As Integer
What I want is when the program Loads, it would display random images from a folder on a website to a picturebox, like: [URL]thats a random pic but, [URL] is the folder of the image?

I want to make a simple screensaver but I looked at what others suggested on how to change screen resolutions and it seems a bit much. So I'm hoping their is a simple way to accomplish this task. Basicly I want the screen to fill reguarless of your screen resolution with the background image coded in the source code. I know the picture will look funny on large resultions but its a sample code Im making, so i'm not worried about streatching a image.My thought was do something to detect window bounds or something.
I have a Vista O.S., but I want my program to change the Ip address on mutiple O.S. with one click of a button or possibly on a timer to switch ip addresses every few minutes. How would I do this in VB 2008?

I've made a program to change a computers wallpaper through VB which works perfectly UNLESS as your browsing for the picture you press the cancel button. The code on the browse button:
Dim dlg As OpenFileDialog = New OpenFileDialog dlg.Filter = "Image Files (*.bmp, *.gif, *.jpg)|*.bmp;*.gif;*.jpg" dlg.Title = "Select the image to load."
[code]....
Is there anything that can be added to the code so that the user is able to cancel looking for a picture without it crashing?
I am having in VB.NET 2010. I am writing an app to change the background wallpaper kinda a little project I am making for my wife's grandma. It is a multiple wallpaper changer to change the wallpaper based on a list of images she adds. Anyways! I have everything setup except the fact that it doesn't change the wallpaper...
This code here:
Public Declare Auto Function SystemParametersInfo Lib "user32.dll" (ByVal uAction As Integer, _ ByVal uParam As Integer, _ ByVal lpvParam As String, _
[CODE]...
Will NOT change the wallpaper but the same code works in VB6 I tried it because I have made something like it before in VB6 but it was a game that changed the wallpaper. Anyways, using the above code in VB6 works(well with a change to the SystemParametersInfo declare to work within VB6. But it doesn't work in VB.NET. I have NO IDEA why everything gets set in the registry just fine from VB.NET but I just cannot seem to get it to update the wallpaper...

I'm trying to update my wallpaper with VB.NET and it's not working. Weird thing is, this same code works fine on my other machines (same OSes, Win XP Pro SP3). My code grabs a random picture then passes it to the SetWallpaper function:
<System.Runtime.InteropServices.DllImportAttribute("user32.dll", EntryPoint:="SystemParametersInfoW")> _ Public Shared Function SystemParametersInfo(ByVal uiAction As UInteger, ByVal uiParam As UInteger, ByVal pvParam As System.IntPtr, ByVal fWinIni As UInteger) As <System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)> Boolean
I have a logon script which changes the desktop brackground picture in the registry. The only problem is this change isn't applied until the user logs off and on again. I currently use a small program which uses SHChangeNotify(&H8000000, &H1000, 0, 0) but this will not refresh the wallpaper. I was also hoping this would refresh the Taskbar because I change a registry setting which removes a toolbar.
i got this code to change the desktop background from a forum.[code]the SetWallpaper function was written by me as the ChangeWallpaper only works on .bmp files.all these code works but my problem is that i need this wallpaper to be stretched because some of my pictures are smaller or larger than 1280 by 800 pixel which is my pc monitor dimensions. i've tried to tweak the ConvertBitmap function (as you can see in the comments) to produce bmp's to my screen size but it doesn't work.i need to set the pictures (.bmp or not) to be stretched and i don't know about dlls and stuff
