In 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()
I have a System.Windows.Forms.Timer named "DialogBoxTimer" set up on a form. When the form loads, it has a command to stop the timer. I have a routine [SPDataRecd(...)] that handles SerialPort1.DataReceived from a serial port (modem). When it is activated by a modem event, I want it to start the timer [DialogBoxTimer.Start()], but it doesn't work.If the timer is running, SPDataRecd can *stop* the timer [DialogBoxTimer.Stop()], but it can't start a stopped timer.
Imagine that I have a System.Windows.Forms.Timer with 1000 ms interval. If I call Timer.Start() method and after 500 ms I call again Timer.Start() what happens? The second Start call will reset the interval or not? Are there any side effects?
I need to load a form and for each form background color, put a square on it, my problem is i can't put the square on the orange backcolor right after the first show of form backcolor, and before the timer even start.[code]
I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
I already created a button "enjoy button" that i want to move in a form when the "timer start button" is clicked.how do link the timer to the "timer start button" and make it move?
this is what i tried so far..then am blank first
Code:Public Class MainForm Dim DX As Integer Dim DY As Integer Dim X As Integer Dim Y As Integer
I'm trying to enable a timer from a SerialPort_DataReceived event. I can see that the timer is enabled, but the event does not fire. It's rather simple, but I need some help understanding why it doesn't run the code in TimerWait_Tick.
When a button is clicked on my forum i need it to enable a timer that has a RANDOM inverval. how to do it or give an example. (im trying to create an autotyper that types a given phrase at random times)

Been doing VB2010 for about a year now, have recently started to push the boundary's for what kind of media I can incorporate into my forms. I haven't been able to play .wav or .mp3 files though. I have tried to follow tutorials on microsoft and other coding websites without success.
So I just spent the last 4 hours trying to find out what was wrong with my code, just to find out that there's a bug in this version or I just don't have enough knowledge of VB2010 (I'm coming from VB6, this is my first program on 2010)I removed the rest of the code just to point out the problem, here it simply tries to enable the Timer1 when you receive data in the SerialPort1
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived If Me.Timer1.Enabled = False Then
[code]....
After this I found that the code inside the Timer1 didn't run when the 100miliseconds passed, so I added a msgbox to see debug.
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived If Me.Timer1.Enabled = False Then
We only have few meetings for Computer subject that's why time did not permit us to discuss timer codes. Anyway, my concern (I think) is just simple (though I really do not know how to start).I plan to make a countdown timer of 60 s that will start once "Start" button is clicked and will display a message box when it reaches 0. I only know the codes for message boxes.
I am wondering if there is any code guide to teach me how to enable the user to draw as many buttons as possible on the windows form and be able to move and resize the buttons on the GUI and also tie the buttons to the timer to toggle the button colour when ever a condition is true
I want to start a Windows Forms Project (VB.NET) using a simple text editor like notepad. I'm not interested in creating a button and other controls from scratch, I just want to know how to create a form, initializing controls without using the wizard.how to use command-line to compile the whole project?
I 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 am using the MaskedTextBox and I am wanting to check for the following:
1. If the length of the text = 14 characters, enable the reset and start button
2. If the length of the text < 14 characters, enable the reset button, disable the start button
3. If the length of the text = 0 characters, disable both buttons
I am able to get most of it to work but when the length = 0, the start button is disabling like it's supposed to but the reset button is staying enabled. Any ideas? I have been looking at this code for hours and can't figure out why this is.
Here is the code.
vb Private Sub mtbClientPhoneNumber_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles mtbClientPhoneNumber.TextChanged 'Make sure that there is a phone number entered into mtbClientPhoneNumber. ValidateUserInput
[CODE]...
To see the form in action, you can see it here. The reset button isnt disabling when length = 0
I created 3 timers, i want each timer to take turn start which means timer1 stop then timer2 start, once timer2 stop timer3 start. But my code seem to be running together once i click the play button.And is there any ways to easy control how my picturebox move? Because my code for controlling it movement need to keep finding the correct number for it to move.[code]

I built a game, that's a basic soccer game. You stop a trackbar, and if it's in the middle then it makes a goal, if not the you lose. I want to up the ante and build my version of brick breaker. I have a bonus timer where if you finish the level within the time frame then you get bonus. When my menustrip is visible then the game pauses. Here's what I got so far:
We've set code to fire certain valves on the timer but once it gets to the last valve (checkbox) I'm not sure how to reset the timer to start back at zero so that it refires the sequence.
Here's the code:
Private Sub Timer1_Tick(ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles Timer1.Tick
I have this code for a Windows service I am writing in .NET....However the TICK function never gets executed regardless of what interval I put in the tmrRun properties. What am I missing? I am sure its something stupid I am not seeing.
