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 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 need to refresh the whole screen/desktop.I am painting a rectangle and need to have it clean and not leaving marks when it is dragged around.There were a few claimed APIs that could do it. And then some others which were more specific to other languages.
View 5 RepliesI am using VB.net in VS2008.I wrote a screensaver that cycles through pictures. When the screensaver exits it sets the desktop background to the last picture loaded using API call SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, sFilePath, SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE).The desktop wallpaper refreshes for WinXP and Vista but not Win7.In Win7, if I run the screensaver as an EXE then the desktop background changes when the program ends. If I run it as a screensaver I need click on the desktop and press F5 before the desktop shows the new desktop background (or click and drag with the mouse to show pieces of the new desktop background).I have tried to add delays and even force a refresh by using SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, Nothing, Nothing) but with no success.

View 1 RepliesI'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."

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?

View 1 RepliesSome of u already know I'm making a 'virtual desktop'- thing.Only one problem. When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.
