Detecting Shutdown, Logoff, Restart, Sleep
Dec 25, 2007What i wish to find is a message or the like that I can use to detect between specific 'shutdown' like events, ie: I wish to be able to find the difference between a shutdown, restart, logoff and sleep initiation.
The problem i have found (as displayed below) is using oClosingEvent.CloseReason the return types provide no further information other then the WindowsShutDown constant (the others are obviously irrelevant in this case).
Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Dim oClosingEvent As System.Windows.Forms.FormClosingEventArgs

VS 2010 - Using System.Threading.Thread.Sleep(5000) To Let My App Pause/sleep For Some Time
May 25, 2010Currently 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..

Logoff A Remote Session?
Aug 9, 2011I have a distributed print control application that is done in a combination VB6 and Visual C++. The application launches at startup on a workstation and waits for a user to login. Once that happens, we track time in the session, along with how many print jobs the guy performs.
We have separate session SW that allows a person to add money to their accounts. The problem is that if there's an active session, typically due to the individual being logged into one of the above mentioned workstations, I can no longer ensure updates to the DB will be atomic.
I would like to have the money terminal send a log off command to the remote workstation session if it detects a user is currently logged in elsewhere. But I'm not sure if there's an existing API for this.

But it doesn't seem to work, Windows shuts down yes but when I re-start the vm and run the app it opens with the old settings, not the ones that I changed before I shut down the vm. Anyone know of a way to do this or to fix the code above, I don't think my OnShuttingdown event is being handled.

Sleep API From Kernel32 / Threads
Nov 10, 2010I have a multi-threaded report engine application. I know that if I want to pause a thread for an interval I can use Thread.Sleep. What I need however, is to be able to suspend the entire process including all threads for a set period of time. In the past, I've used the Sleep API from kernel32.
It appears though that it's only "sleeping" my current thread and not the entire process which is not what I expected (now that I've read the documentation I realize that Thread.Sleep is probably the managed implementation of this API which is why it behaves as it does). So, my question, how do I force the entire application (and all of its threads) to pause the for the interval and not just the thread calling it? Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Int32)
Threading Pausing Not Using Sleep
May 20, 2009I know there is always better ways of doing things. Normally when you create a thread and I want it to pause/sleep for a set amount of time I use the <Object>.Sleep(1000) but this is frowned upon in .Net2+.

View 8 RepliesWpf - For Each Loop Doesn't Sleep
Nov 1, 2011I have a For..Each loop which loops trough all grid's rectangles and changes the fill of them randomly. I change the fill with a color animation. Here's my code:
Dim rand as new random
Dim changeColor As New Animation.ColorAnimation
changeColor.Duration = TimeSpan.FromSeconds(0.5)

The problem is that the loop doesn't sleep. I want to trigger the animation, then wait until the rectangle fill is changed and then continue with the rest, but it seems that all of the rectangles fill are changed in the same time.
