View 1 RepliesAlarm Clock - Launching App @ Certain Time
Dec 4, 2010I would like to make an alarm clock application, however I am having some problems in the brainstorming phase.
My main problem is the fact that I dont know how to ensure the application will be able to calculate the time and thus set off the alarm. For example, when the application is closed, how will the alarm go off?
Ideally I would like to make this app a system startup item, so if the system is rebooted, the application will automatically relaunch - but again, I dont know how to do that.
If the system is sleeping, how can I wake it up? These kind of problems.
Another dilema I have, is if this application is always running, how could I have it go to my taskbar hidden icon menu (the right section of the taskbar next to the time).

Trigger An Alarm On Specific Time?

I have the option to start an alarm and set it to expire at a specific time, say in 2 days 5 hours 18 mins 10 secs. I was wondering what would be the best way (performance wise) to achieve this.

I get this error: An error occurred creating the form. See Exception.InnerException for details. The error is: Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown.
When I that line of code it runs, but when the alarm goes off there is no sound. And having a alarm clock go off with no sound is not going to get one up. I do have wmp com control on the form.

View 2 RepliesAlarm In Access 2007 - Compilation Error: External Name Not Defined
Jul 25, 2011I'm using access to replicate something that is very simple in excel. I have one "due date" column, and I want the cell right next to those cells to tell me if there are less than 15 days to that date. In excel is a simple conditional function, but I want to do it in Access because it looks better.I'm new to access and even though I've been reading some posts and forums I haven't been able to pull this out. I tried to program a macro with the following
Sub Alarma()
[Alarma] = IIf([Fecha de vencimiento] - 15 > Date(), " ", "Faltan menos de 15 d�as")
[code]....
It shows the following error -> Compilation error: External name not defined.
So, it's not reading the "Alarma" field... how do I define this field? It's inside a formulary, and Alarma is the title (I downloaded a template from the internet and changed the titles so I wouldn't have to do it from scratch...)

View 6 Replies.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec
Jan 15, 2009I need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?
UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:
Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000
It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.
Asp.net - Local Static Variables In Timer.Tick Event (Stopping A Timer)
Jul 9, 2009I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?
Synchronize The Timer Event So That The Timer Executes From The Background Worker Thread?
Apr 23, 2009I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.
My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.
1. How can i close my background worker and at the same time have the timer to be stopped?
2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?
3. Is there a better approach for me to adapt?
Create An Array Of Timer - Raise The Tick Event For A Particular Timer?
Jan 11, 2011I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.

.net - Systems.timer.timer Unwanted Multithreading?
Jul 14, 2011I recently switched my code from using the windows.forms.timer to the systems.timer.timer and it has resulted in a multithreading error. I'm using the timer to trigger just one event so multithreading shouldn't be an issue. To give more detail I have implemented the timer at follows:
At the top of the class I have: Private Shared timr1sec As System.Timers.Timer
When the program loads (Private Sub Test_load):
timr1sec = New System.Timers.Timer(1000)
AddHandler timr1sec.Elapsed, AddressOf OnTimedEvent
In OnTimedEvent I call several subroutines, and write some data to the screen using a ListView object.VisualExpress throws the multithreading error on the last line of this code, which is in OnTimedEvent
