Feb 24, 2011In a vb 2010 project, I have 2 win forms: Form1 and Form2.

Put A Timer On The Form That Needs To Be Auto-Saved?
May 5, 2009I am creating AutoSave functionality for an application. Its an mdi application. it needs a seperate form where the user can turn AutoSave onoff and set the interval in minutes for it to execute. The users values for these i plan to saveupdate etrieve into my.settings.
I plan to put a timer on the form that needs to be AutoSaved. If the user turns off the timer from the options form, how would i go about stopping the timer on the form that needs to be saved? Should I change the timer to be "Shared Friend" and access it directly from the options form or what?

Making A Timer Form And Event?
Jan 23, 2011I 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
Resize Form Using A Timer Or A For Loop
Feb 12, 2010I have been battling with resizing a form in code, using either a timer or a for loop. When I say resizing, what I want to do is create the effect of a rolldown/rollup window. On my form, I have a groupbox with search criteria options, and underneath the groupbox, I have a datagridview with several buttons.
The effect I'm trying to create can be seen in Windows XP Security Centre; when you open up the security centre screen, you have your firewall, automatic updates and virus protection areas; to the right of each, there is a small round button, with either an up or down arrow, depending on whether the section is rolled up or down. When you click the button, the section rolls down or up smoothly.

View 10 RepliesEnable And Start Windows Form Timer?
Jun 16, 2011In my Windows Form's application, I enable and start a Windows Form's Timer for a state machine which interacts with various User Controls. In one part of the state machine where an external device is being rebooted, I need to disable the User Interface (a User Control's UI) for the time it takes the device to reboot. The problem exists in that once I use System.Threading.Sleep, the timer that fires the State Machine stops and never restarts. I even re-enabled the Timer and re-started it after the Sleep command but to no avail. Is this expected operation or should a Windows Form's Timer be able to restart after a Sleep?
Snippet of code from a step in the state machine below:
Cursor.Current = Cursors.WaitCursor
MainForm.Enabled = False
System.Threading.Thread.Sleep(8000)
MainForm.Enabled = True
Cursor.Current = Cursors.Default
MainForm.t1.Enabled = True
MainForm.t1.Start()

Setting An Interval For A Timer In A Textbox On The Form
Mar 31, 2010I don't know much about vb.net so I'm hoping this is something that can be done fairly easily. We currently have a system where valves are fired by checkboxes (representing each valve) being checked at certain intervals and when the last valve is switched the timer restarts in order for the sequence to repeat itself. We would like to be able to have a textbox in the form where we can just type in the interval at which the valves (checkboxes) switch without having to change the interval manually in the code each time we want to change it. Currently in our code we just have a set interval. Here's the code:

View 6 RepliesVS 2010 Showing A Form In Timer Event?
Feb 9, 2011I am using a timer control to display a message form in my application, but it's not working the way I want it to. Currently, when the timer event fires I create a new instance of my message form & display it. But if the user is away from their desk & doesn't close the message form before the timer fires again, a new instance of the message form is created & shown. So how can I check to see if the message form is currently shown on the screen so multiple ones dont get displayed? This is my timer event:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Using frm As New MsgForm

Do I need to use the default instance of the message form instead of creating a new one?

I am using Label.Text = counter where counter is a string that is changing.

View 1 RepliesTimer Control On Child Form Crashes VS 2010?
Sep 7, 2011I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

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?
