View 2 RepliesCurrently 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..

is there anyway to sleep a thread for a "tick". i.e. the tick in StopWatch.ElapsedTick. right now the best i could achieve is this thread.sleep(1). i need it faster

I 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)
I 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+.

I 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)
[code]....
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.
Is there is way to delay loops without using (Sleep or timer) in VB
Because on java you cant do something like this
For(i = 0; i< 100; i++) {
Event.Wait(3000)
Animate(i);
}
I dont want to use sleep because your control is dead while is at sleep And using timer waste memory and process timer plus more coding is needed!
I have an application that detects a Power mode change using.
SystemEvents.PowerModeChanged
if there is a way to detect if the system is going to sleep or hibernate?
To start off with, I will say that I have tried ENDLESS attempts to surpress/capture/stop the actual sleep keystroke.
The code cannot require administrator privilege's. .
I tried:
Private Overrides Sub ProcessCmdKey, and Return true when the sleep key is pressed - did not disable sleep key LowLevelKeyboard - One that can disable the windows logo key - did not disable sleep key And many other keyhandling events, etc.
The code cannot create registry keys because that requires admin privilege's.
[code]I send the Thread via Thread.Sleep to sleep mode when nothing happens here. Does this affect the TCPListener in his work somehow and what happens to an incomming connection while the Thread is in sleep-mode?
View 3 RepliesI have a frm_Main, which starts a thread. The thread then goes and calls a module, which has a thread.sleep() in it. This causes the mouse to freeze up while it sleeps, despite being called by the child thread. I thought this would have be on the thread time-slice? However it is causing my form to freeze for the sleep duration.

Ok so I have been playing with VB.net and brainstorming ways to accomplish launching a thread reliably every 60 seconds reguardless of how long the prior thread took to do it's work. Here is my question. Given the following code:
[Code]...
My assumption for this output would be that the time between each line would have to be exactly 5000 milliseconds plus the time it takes to execute the rest of the loop which could vary given that there could be an unknown delay due to disk IO. My problem is that looking at lines 10 and 11 and subtracting gives me a difference of 4,958 milliseconds. So my question is what the heck is going on there? How is it possible to get a difference of less than 5000 milliseconds when I have told the thread to sleep for 5000 milliseconds before completing the process. What am I missing?
Is there a VB.NET code that I can use to make the computer sleep, restart, logoff, and maybe switch user too?
View 3 RepliesI am trying to learn how to use Thread.Sleep properly as the main problem I am facing when using it is the fact that the window/form on run time would not move until after the sleep time has elapsed. Did I miss something? Below is a short example of what I want to achieve.

"'I'm having an issue sorting out why my code isnt working. When I "step into" it line by line i can get it all to work exactly how I want, however when I actually run the macro i get an subscript error 9. The code basicly sets a .CSV url to a variable "CurrentURL". The code then launches this url which opens a .csv window called table.csv. I want to copy 2 columns off this window and paste it to another document called "MPT_CAPM_v1", then close table.csv. Here is my code the red line is where I believe I'm running into my error.'This macro opens a URL, copies and pastes the price data into the sheet
[Code]...
I think the error may be caused by the fact it takes about 4-5 seconds to open table.csv in excel, and my line of code is trying to select a window that isnt currently open. After I get the error message, table.csv opens up. I've tried Loops & Sleep functions to try to input a delay, but regardless it seems that table.csv will not open until the end of said loop or delay.
Is there a simple sleep function in Visual Basic that doens't involve thread.
Something similiar like there exists in: C: sleep(1);
We also tried this code:Declare Sub Sleep Lib "kernel32" (ByVal milliseconds As Long)' pause for 5 seconds
Sleep 5000 but it didn't work. It gave me this error: PInvokeStackImbalance was detected

I am trying to differentiate between sleep and hibernate when I catch a Power Mode changed event and I am quite stuck.
What I am doing currently is I catch this: SystemEvents.PowerModeChanged and get the mode of the PowerModeChangedEventArgs which can be PowerModesSuspend amongst others. My problem is that both sleep and hibernate cause the same event.
