I had a Line drawn from design view, and a circle also drawn in design view. Now like a clock, I want the Line to follow around the circle, this will be mostly a timer, or something. So far i have
Public Class Form1
Public myRadians As Decimal
Public myDegrees As Decimal
Public ychange As Decimal
[code]....
but its so messed up, the lines dont follow, they go everywhere...
I require the Login button on the User app to be enabled at a certain time during the day, and the Admin will specify the time. How do I go about achieving this? I have a database as wellDo I save the time in the Database that the Admin enters, and then retrieve the time from the database when the User app is running and compare the clock time on the User app to the time from the database (I will retrieve the time when the User app starts)

But I'm Having a hard time with the MP3 Part of it all.I want a pre-selected MP3 to start, when my timer2 is = to the time of day.But i Have never really used MP3's in any project. So dose anyone know how i would go about.

View 2 RepliesI am trying to write a small program that shows a clock using a timer in vb.net, I want the clock to display the time and date as a binary display i.e. if it's 10:01:21 the clock would display boxes or buttons in rows going from 1 to 2 to 4 etc upwards and changing colour when at certain times. the example time above would be a button for 8,a for 2 to make the 10 o'clock, a button for the 1 minute and a button for the 16, 4 and 1 seconds making 21 seconds.
View 1 RepliesI'm in need of a "global" type timer that will allow me to basically run a clock the entire time someone is on my site, no matter what pages they go to. I've played around with the timer available for forms but I didn't see a way to make it continue to run after someone left that page.The effect I'm attempting to create is for a timer to start whenever someone hits my site, then every X minutes an event will trigger. This event should happen no matter where they are on the site. I've read a couple articles on timers but to be honest I'm fairly new to VB and I didn't know if I really needed to learn about 'threading' etc, to get a timer to work.
View 2 RepliesI am currently developing an application in which I would make a form full size automaticly.On the location where I set the time parameters, lets say, I want an event to occur every 2 hours, in which the event would be a form becoming full-sized and, on that form a clock which would show that the form will resize on its original state after lets say, 15 minutes.And also I would like to disable the Windows Start keys.I tried some codes but they were for an event if the key is pressed.For this I need the keys to be disabled as soon as I start my application.For the full size form I have used this code:
Me.Height = My.Computer.Screen.WorkingArea.Height
Me.Width = My.Computer.Screen.WorkingArea.Width
Me.WindowState = FormWindowState.Maximized
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None

I'm a totally newb to VB and I want to do this. I want to do display system clock into a textbox. The trick is that I want it to be synchronized with the Windows XP clock. I want to have something like +/- 100 ms accuracy.
Each 'second' change will trigger an output pin to ground into the parallel port. This is very important that the 'second' change in the same time the Windows XP second change. Do not care about the parallel output thing, I'm nearly there. My main concern is the synchronisation with Windows clock.
In my code, I've added a counter that increment +1 at each 'second' change. So, when the 'n' value will reach a determined value, it will trigger another event.
[Code]...
I searched on the net and I found a thing about NIST time server.. Maybe this could be an otpion, but I have even no idea about how using it... I'm a total newb, but I'm ready to learn. So, please use simple language, no hard to understand acronym etc.

View 6 RepliesI 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.
I 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?
I 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?
I 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.
How can I incorporate the timer so once a page loads the timer activates, waits a few seconds then I tell my program what to do next.I tried this code but it didnt work:

Timer1.Enabled = True

By the way is not a problem of mouse_event, is the timer that doesn't work
I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend
I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]
I 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
