I am creating a program which displays text to the screen.
I would like to be able to set the program to have a timer so that when the user has selected the letter, after say 5 seconds a new letter appears.
I have added the current code below.
Code:
Public Class Form1
Private Display As Boolean
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
[Code].....
This is the current code I have so far[code]...
Currently the program starts by displaying a character to screen, but I would like it to first wait 5 seconds before displaying the first character.
Then the character should not change until the user presses the corresponding character, upon which after a further 5 seconds a new character appears.
am really getting to know more about programming each day. really interesting.
i have a form with some labels.. i need each label to display a text after certain time of the time count. i have this piece i put together.. didnt work but i guess it need a little professional touch.

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
My timer pauses (sort of the display portion (label) of the timer indeed pauses, however when the timer is resumed it starts again, but not at the point where it was disabled. As an example. If I pause the timer at 10:00 and wait ten seconds when I hit resume it starts at 09:50, where it should resume at 10:00 or 09:59
Module Helper
Public SessionTime As String
Public Pause As Boolean = False[code].....
I am trying to display a countdown from a timer.
Dim r As New Random()
Timer1.Interval = r.Next(60000, 300000)
Timer1.Enabled = True
'Display countdown in 'Label2'
Also, I have a long mess of code (follow my signature) that compiles a sentence and displays it in a label. It works fine until I add the loop around the whole thing. Then it does nothing at all.~~the code is not finished. I have a lot of filters to put in place.

I have a quick question regarding the serial port and timer tick event. Basically i have a micro processor connected to the PC via the serial port. With a baurd rate of 38400 set.When the PC sends the micro ":K + VBCRLF" the micro response with a string of information (ASCII encoded) and delimited with a "," and at the end of the transmission a cartridge return line feed is added.Example of sent string:
"12,1134,123,545,76,6868,34,232,1,2,3,6,7,8" These numbers are then split using the VB mystring.split(",") function into an array of strings, then the numbers are converted using ctype. After which my UI is then updated.I have Witten the code in a tick timer event using a timer count of 300ms. Although the program runs and the UI is updated i end it with lots of exception errors. I think allot of this is down to the serial port either timing out or not reading complete string.Or possibly the timer has not executed all the code before another tick event happens Even after adding a few try catch statements i am still having problems. Can anybody suggest a better way of doing it?I was thinking of using a do while loop and at the end a sleep function instead of the timer tick event.I need the speed as i am trying to read and display live data.

View 1 RepliesStuff like this makes me hate computers! Anyways, I'm again struggling with something relatively simple - or so i thought.I have a sub:

Then, I have a sub that runs every minute, calling yet another sub, which calls this one. Before you say whoa! that's too many, I'll say that each of these subs has a different purpose.The whole problem is that the WriteToFile sub writes only once to a file! Instead of continously writing to the file every minute, it stops at the first line.

the code i am using is Error is raised when the last item in the listbox is selected.

In a piece of code I am writing I am trying to change the text of a label in my form based on a timer. I have MANY other labels that are all updating in their own subs and when I try to add any new labels(in any sub) to update it wont. I am using Label.Text = counter where counter is a string that is changing. I have tried refreshing the form, Label.refresh() Label1.Update()....The only thing I think it could be is that the redraw is being held up by other calculations on the cpu. How can I make the label text change and update properly?

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?
