WIndows 7 Desktop Refresh And Picture Screensaver?

Nov 9, 2011

I 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.

Jun 4, 2012

I don't have any idea if it is possible and how can I code it.I have created an application that needs to run on a non-administrator account on windows 7. It won't run if the PC goes sleep/ locked/ hybernate/ on-screensaver. So, I want to disable them programmatically using vb.net 2010. Can any one help me?

By the way, I already tried to edit the power settings of the PC so it will never sleep/ hybernate, etc. But unfortunately, it keeps on sleeping after few hours.

Way To Refresh Desktop Wallpaper

Feb 14, 2011

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.

Desktop Showing Through Picture Box On Second Form?

Nov 10, 2011

I'm new to .net programming, but I do have some experience programming. I've used a picture box to make a custom button. It works on the main form, but when I open a dialog form with the same image the transparent areas shows the desktop and not the dialog. Thishappened for images with an alpha channel and also images that used the transparency key. I tried it with a winform instead and the images with an alpha channel worked fine, but the transparency keyed images showed the screen. All

Invalidating Splash Screen - Picture Box Doesn't Refresh With Image

Jun 21, 2010

I have a splash screen and want to test the loading bar. The % of loading are in 11 stages (0-100% in 10% intervals) and I have 11 different images. What i'm trying to do is set my picturebox.image = to the resource image and then wait 1 second then set picturebox.image to the next resource image. What i was doing is on the SplashScreen.Show method [Code]. What happens is that the picture box doesn't refresh with the image until the last image has been loaded from the procedure and the end of making the thread sleep completes. (this worked fine in VS2005). How can I make it load up the image, redraw the picturebox and then make the thread sleep for 1 second in VS2008.

Refresh Combo Box In Windows Form?

Controlling Windows Remote Desktop?

Mar 8, 2010

I am trying to overcome a problem I am having with remote desktop.Basically I have 2 machines running in different locations. I use remote desktop to access one of them (the "Remote Machine") from the other.("My PC")The "Remote Machine" is performing automated tasks that require the screen to be active, not the user login screen.

When I do so the Remote Machine logs off and presents the normal windows login screen.When I am finished reviewing the remote machine I log off and then I need to log back into the "remote" machine. It has no monitior but I can log in by pressing the enter key which sends a keypress to log into the user account( there is only one). In fact I do this the other way around. I press the enter key on the "Remote Machine" and this logs the user back in - terminating the remote session on "MyPC".

The problem is I have to physically go to the Remote Machine to press this enter key.This is a hassle - One solution is to remotely re-boot the remote pc but the lead time involved is too great.I am unable to fix this problem by tweaking setting or registry hacks so I guess the solution must be to cause the remote user to log back in programatically.I am an experienced VB user but I have never worked outside the windows environment. Ideally I would like to programmtically send a keystroke "{enter}" to the login screen but this doesn't work.
