I need something that will log the time the computer came out of standby, or the user logs in the first time from a reboot.
Basically, I want to time computer usage but in simple terms where computer is being used after waking or after rebooting.
So, All I need is a detection scheme. Does windows provide that? I am probably targeting .NET but can do Win32 API. Or do I have to do anything like that all?
I am thinking if I make a service, windows will handle the launching of the service and that way I can detect usage. But is that the most efficient way?
Is there a way to do it in c# or vb.net? I have to bring a system out of standby and play a notification sound if it is in standby mode, at specific time intervals.
there are two ways windows standby the computer by itself, close the lid and if the computer is not being used for XX minutes. however, there is a difference, when i open the lid the computer goes out of standby automatically but only if it was caused by closing the lid, but the other does not. so how do i use the lid-standby in VB? [code] and the device in manager "ACPI Lid" has no wake up options, like i have with some keyboards and mice.. so what is the difference, and how do i cause the computer to wake when i open the lid after the standby is initiated?
How can i do this for pocketpc? I have tried this but didn't work since its made for windows not for windows mobile. Can anyone help me? Please.Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags as Long, ByVal wReserved as Long) as Long

I was making a little timer. When the phone is not in standby, my app is working fine. But when i put the phone in standby it stops. When phone is coming out of standby, the timer is going again on the time i put the phone in standby.
I know that other tools keep working, so i there a simple way to do that?
Title pretty much says it all. Does anyone know a way to to prevent a computer from entering a low/non-processing mode while the program is running? I don't care about monitor modes, screen-savers, hard-drive spindown, etc (in fact, I'd prefer to leave those alone; I like it that it shuts the monitor off after a time period).Basically, I have an industrial program that needs to continually monitor a PCI card it uses for IO; and this activity alone isn't enough to convince Windows not to go into Sleep mode. We normally just shut the power-save features off, but we had an incident where a technician forgot, a customer's machine went to Sleep after the end of the shift, the pumps stopped recirculating, yadda-yadda big mess.
My program is supposed to display a randomly generated sentence on the screen (something like a screensaver) Then 'wait' for a random period between 1 and 5 minutes before cycling through to generate another sentence. How do I do that?
I'm using Visual Studio 2005 (with Visual Basic) to create my own personal web site. I want to include a page that has my resume, but I don't want the format to be affected. What would be the best way to do this. I thought that possibly putting it in as an image might work, but I haven't tried that yet.
After I get this done, is there a way to add a button so a user can download my resume?
I have a case where I need to resume execution on the next line after an exception. Is there no way to do this using the structured error handling? I realize that I can go back to the "On Error .. Goto", but I can't believe there's not a way to do this with structured error handling...

I'm trying to get this routine to resume the downloads.I use the same routine to download a file all the way thru non-stop..so at least the download part is working..however either the stop commands i'm using or the resume routine i thought would work is all ass backwards I'm not gonna make any conclusions or anything on this one..made myself look stupid the last time i know you all are def smarter than me when it comes to this stuff,,and dangit that just erks me to no end i tried adding a exit do in the do loop..and that of course exits ok,,but when the file is resumed is larger than its supposed to be.
I've been trying for about a month or so but been busy recently so couldn't address it then. Here is the code.

I know that even when the timer is disabled, it still keeps on accumulating so I need a way that when the timer is paused, the timer doesn't keep on accumulating and when the timer is resumed, the timer continues from where it was when it was paused.
Is it possible in visual basic to suspend and resume processes. As in entirely pause a process (threads)?I mean an external thread. I'm using Visual Basic 2010 Express btw.
I'm working on a project in VB.net which takes large text files containing T-SQL and executes them against a local SQL database, but I've hit a problem in regards to error handling. I'm using the following technologies :
I have a a main thread and another background thread that does some work (see below).I want to do something within my worker thread and then wait until some other event happens in the main thread before continuing. How do I do this? I thought I could use ManualResetEvent but I can't get it to work properly. I'm a bit confused about the Set, Reset, WaitOne methods and where exactly I should call them from.When the worker thread is suspended it shouldn't affect the main thread.

I want to make a download Manager with resume capability (dont refer me to codeproject examples which use httpwebrequest and webresponse classes) i want to make the use of system.net.webclient class. I know it can provide me with events and stuff but is it possible to resume our downlaods with this class ?
Ive got a container with a bunch of child textboxes stacked using dock top. My code updates the textboxes and they vertically expand/contract etc. I'm thinking that my code might run faster if I turn off the layout refreshing until all the updates to the textboxes are done.
I'm getting confused with what I'm reading about suspend/resume layout - do I need to suspend for ALL the child controls, then go through them all at the end and Resume individually?
It seems that there is a glitch in Vb, While having some tasks ( Thread ) queued using Tasks if you try to use Invoke, the thread do not resume when the delegate returns.If BeginInvoke is used, it works but the problem is that it become impossible to execute a delegate synchronously.This does force the use of the AutoResetEvent to control the thread.The problem comes when the thread execute some code in a other classes, using a single AutoResetEvent within many classes just give a very dirty code.
I'm not talking about On Error Resume Next, that simply ignores the error. What I want to do is fix it, then continue with executing the procedure-but I can't find a way to do that, other than enclosing every single line of code in its own Try/Catch block. Nope, don't want to do that-isn't there another way?
I have searched a lot on Google about Pausing and Resuming Downloads and I find the examples with background workers but I don't understand them and that is why I can't change the code according to my app.Is there an easy way of doing this or do I have to do it the hard way?
