.net - Yield/Sleep/throttle Another Thread While It Is Executing A Method In An External Library - Specifically Jurassic?
Jun 25, 2012I am using a .Net JavaScript implementation called Jurassic to run user-controlled scripts within my .Net 4 WPF application coded in VB.Net - C# answers are fine. The script engine runs on its own thread and provides an API for the script to interact with my application. This all works really nicely until a user executes a script that causes an infinite loop and takes out a core of the processor.
[Code]...
The reason I care about keeping the thread alive is because the user who wrote the script and the user who is running it may not be the same, and I want to keep the experience as smooth as possible the the user running the thread. There also might be legitimate situations in which a single JavaScript function would run for a long time and I do not want to kill that, I just want to stop being allowed to hog the resources.
Solutions that involve stopping the thread from slowing down the system but that still show high CPU usage are not preferable because I do not want the user to wrongly feel that the application is resource intensive.
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..

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)
[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.
Delay Loops Without Using (Sleep Or Timer)
Dec 20, 2009Is 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!

Disable Sleep Button On Keyboard?
Sep 12, 2011To 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.

View 3 RepliesForms :: Threading And Modules And Sleep
Mar 31, 2011I 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.

Inconsistant Thread Sleep Timer?
Apr 5, 2011Ok 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?

Pause In Code Can't Use Sleep Function?
Jan 4, 2011"'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.
