My app is running in the tray and I want it to give a reminder to the user its there when they resume from a hibernation, sleep, or from being locked. I know how to handle the popup, but I cant find out anywhere how to detect that 'wake' status from those power saving modes.

if there is a way to detect if the system is going to sleep or hibernate?
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.

Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..
View 5 RepliesI 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.

View 9 RepliesI am looking into programming an application that detects noise levels. If the level is over a specific threshold it will lock a logged on user account. The idea behind this application is to reduce noise levels in a busy IT suite. My question is has anyone written anything similar and did it prove to be effective and is VB the best programming language for the job?

View 2 RepliesI have a weired problem. I developed a multithreaded WinForm application using VB.Net, and SQL Server 2008. The application works perfectly fine if I am using Visual Studio IDE to run the same. But, if I run the exe file created by VS the application hangs in case I lock my system and again relogin. The memory usage is same as it was before locking the system. CPU usage is also 0% or by max 2%. All threads are also exited after finishing there designated tasks.The application also uses threading but all threads are exited after there designated tasks. I confirmed this using various tools.[code]

View 4 RepliesI want to write a simple program, which should inform me before any files getting open (like as User account control in Windows Vista or Windows 7). I came to know that all antiviruses use this technique to detect viruses before they are affecting the system. My program must ask me as "Are you allow this file to run?" and allow it if I allow otherwise terminate the file.
View 2 Repliesborder of that said window so the only place the mouse can't click the titlebar and the minimize,restore, and maximize button. The height of the titlebar depends on what OS the user is using so I'm having trouble because I can't give a definite value for this. How do I detect the height. and also for border i'm not sure if the borders have different widths with different operating systems. I'm using windows XP on classic mode, when I change to the themed mode, the height of the title bar changes so it won't work.

View 8 RepliesI am trying to create an icon in the system tray as status for num-lock, caps-lock, and scroll-lock, because my keyboard that came with my computer does not have status lights on the keyboard, and only on the system tray.
The program however that came with it, does not like to work when I have some games open and stuff, it works usually in IE, and most other programs, but some programs just seem to interfere with it.
I have made a new program on a 1 mili-second timer for the 3 and it seems to work just fine in the application, I was wondering now if I could move that over to the system tray and make it look like the one that came with computer, it has 3 different icons, and the icon changes for on/off and has a tooltip status change on mouse-over showing status of on/off.
I've been trying to use "System.Threading.Thread.Sleep(15)" as the delay code but if freeze the form. I used this "Location.Refresh()" where location is the name of the form, but it didn't give me what I need. This code is going to work on a ProgressBar while typing and the value of the progress bar change while typing. The progress bar jumps to the new value and I want it to move. So I thought about puting it in a "For ... Loop" but the whole form freezes.
