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 2 RepliesI'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.

The coding that I have a problem with might make people think that I am creating some malware. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running.
So this is the script:
Private Sub CheckAndCloseiTunes()
retry:
'Custom class that includes the function to safely close iTunes
Dim Processes As Process() = Process.GetProcessesByName("iTunes")

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 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.

im trying to terminate a threading.thread using thread.abort the thread runs a download connection so is usually in the middle of socket.recieve or socket.send or socket.connect when aborting i just want to terminate the thread no matter what thread.abort raises an MDA excpetion. so i ticked it off in the debug exceptions menu. now it doesnt raise an exception, but the thread simply wont terminate. my program wont close unless i press top in the debugger.i cant pause downloads because i cant terminate the thread this code wasn't working?

as for the exception concerning threads being aborted from other threads being dangerous, how is it possible to send a message from a main thread to another thread to abort itself? as far as i know the only way to a abort one thread from another is to just kill it (because i dont know of ways for a thread to communicate with another).
Is there a simple way to determine how many milliseconds I need to "Sleep" for in order to "emulate" a 2 mhz speed. In other words, I want to execute an instruction, call System.Threading.Thread.Sleep() function for an X amount of milliseconds in order to emulate 2 mhz. This doesn't need to be exact to the millisecond, but is there a ball park I can get? Some forumlate that divides the PC clock speed by the 2 mhz or something?

View 3 RepliesOk 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:

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?
I 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.

In a WinForms environment, I want to wait a specified amount of time before hiding a user control, but I don't want to freeze the entire UI. I can't kick off to another thread because I have to service the UI components on the thread they were created on. What is the cleanest way to do this?

I have a control thread that starts up a secondary thread and when the secondary thread finishes, the control thread restarts the secondary thread. On this secondary thread, I use a stopwatch to record a thread.sleep event. Is there any reason, under any circumstance, why the stopwatch elapsed millisecond value (499) would be 1ms less than the sleep time (500 ms)This doesn't happen all the time or even a lot, I'm just curious if there is any physical reason for this to happen.
