View 1 RepliesI have been playing about with the WM_SYSCOMMAND Message and more specifically with the SC_SCREENSAVE parameter which is a cool way to pick up when the screen saver is activated as seen below:[code] What I can't seem to find is if there is a way to detect when the screen saver comes off.
View 4 RepliesI have an application than disables the screen saver temporarily in order to run a slide show. I use this to turn it on or off:
i = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, active, Nothing, SPIF_SENDWININICHANGE)
This works fine in XP. In Windows 7, it disables the screen saver properly. However, when it is enabled again, at the normal time for the screen saver to come on, the system asks for a password instead of showing the screen saver.From this time on until the screen saver settings are adjusted in the control panel, the password screen is displayed in place of the screen saver.Is there something else I should be doing for Windows 7? I understand that SPI_GETSCREENSAVEACTIVE is not supported in Windows 7, but SPI_SETSCREENSAVEACTIVE is supposed to be.
I am trying to allow the user to launch the Windows Screen Saver by clicking on a button. I have the following code:

View 1 RepliesOur program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.

This kind of goes along with my Shut Down & Restart thread from a few weeks ago, but one of the things I'm wondering is if it's possible to detect if the system has Hibernation enabled, or in the case of Win2k if hibernation is even possible.I already know how to hibernate the computer via the Framework:Application.SetSuspendState(PowerState.Hibernate, True, True)but in my program I would like to provide the hibernate option only if the OS A) is new enough to be able to and B) has it enabled in the user's Power Options in the control panel. I can't seem to find anything via Google and MSDN that leads me in the right direction.

However, when I click standby, the pc hibernates too.I want to disable and re-enable hibernation, but I need to detect whether it is enabled or not, because I don't want to enable it if the user has disabled it.

View 7 Replieshow make simple Screan saver screan saver contain videos and images
View 5 RepliesBTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?
View 11 RepliesI am writing an application that puts a computer in hibernation mode (Application.SetSuspendState). I have noticed that there exists a specific option that needs to be enabled for the machine to hibernate correctly and that is found in Control Panel--> Power Options --> Hibernate Tab (if this option is not checked then the machine goes into stand by mode rather than hibernate) Is there a way to programmatically check the status of the "Enable Hibernation" check box and check/uncheck it?
