I have this code
private void picTop_MouseEnter(object sender, EventArgs e)
{
if (timer1.Tick == 10)
{
picBottom.Visible = true;
picTop.Visible = false;
timer1.Stop();
}
else
{
MessageBox.Show("ERROR You cannot view this section at this time.\nPlease try again later.");
}
}
private void picBottom_MouseEnter(object sender, EventArgs e)
{
picBottom.Visible = false;
picTop.Visible = true;
timer1.Start();
}
My timerinterval is set at 1000ms (so 1 second)
I only want the user to go into the top panel again after 10 seconds.
Some help would be greatly appreciated.
Current error I get: timer1.Tick is red underlined, error=
"The event 'System.Windows.Forms.Timer.Tick' can only appear on the left hand side of += or -="
Timer.Tick is not property its an event.
Use it like
timer1.Tick +=
{
picBottom.Visible = true;
picTop.Visible = false;
timer1.Stop();
}
For interval use timer.Interval
timer.Interval = 10000;
Ok. I think I understand what you're trying to achieve...
You have 2 areas on your form called "Top" & "Bottom"
Once the user enters & subsequently leaves the top area, you don't want them to be able to enter again for 10 seconds. is that correct?
So you've got a few problems... first of all, Tick is an event to which you would attach a method to be fired when it is raised. it's not an integer you can check. The only integer property on a timer of relevance for timing for is called Interval
But aside from that I don't think your method is going to be particularly effective.
Perhaps a better idea would be to add a MouseExit event to the top area. and disable that area for 10 seconds. and use a timer to re-enable it.
timer1.Tick += timer1_Tick;
public void Top_MouseExit (object sender, EventArgs e)
{
PicTop.Visible = false; // or hide/disbale it some other way
Timer1.Interval = 10000; //10 seconds
Timer1.Start();
}
public void timer1_Tick(object sender, EventArgs e)
{
timer1.Stop();
PicTop.Visible = true; //renable the top area
}

I'm having trouble with mouse click event in a timer in c#.
My timer's interval is 100 and set on True, i want to make action each 100 ticks and indentify the type of click in. I want to play the action each 100 ticks when a mouse is pressed, but this only plays one time.
EDIT: I don't want to have to enable/disable the time.
private void timer1_Tick(object sender, MouseEventArgs e)
{
if (MouseButtons == MouseButtons.Left)
{
//Action...
}
if (MouseButtons == MouseButtons.Right)
{
//Action...
}
}
100 ticks is 0.01 milliseconds and Interval is an integer so I used seconds for this test.
This webform will detect the last clicked mouse button and change the timer interval in the timer tick event based on the mouse button that was last clicked. I also added a label for visual indication:
public partial class Form1 : Form
{
Timer t;
MouseButtons lastMouseButtonClicked;
Label lblStatus;
public Form1()
{
InitializeComponent();
lblStatus = new Label()
{
Text = "No click since tick."
,Width = 500
};
this.Controls.Add(lblStatus);
t = new Timer();
//A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond, or 10 million ticks in a second.
//t.Interval = (int)(100 / TimeSpan.TicksPerMillisecond);//0.01 ms
t.Interval = 1000;
t.Tick += T_Tick;
t.Enabled = true;
this.MouseClick += Form1_MouseClick;
}
private void T_Tick(object sender, EventArgs e)
{
switch (lastMouseButtonClicked)
{
case MouseButtons.Left:
//Action...
lblStatus.Text = "MouseButtons.Left";
t.Interval = 1000;
break;
case MouseButtons.Right:
//Action...
lblStatus.Text = "MouseButtons.Right";
t.Interval = 3000;
break;
default:
lblStatus.Text = "No click since tick.";
break;
}
LastMouseButtonClicked = MouseButtons.None;
}
private void Form1_MouseClick(object sender, MouseEventArgs e)
{
lastMouseButtonClicked = e.Button;
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
The timer interval is changed to either 1s or 3s depending on the mouse click. You could also change the interval in the mouse click event to simplify it.
Here is an example:
public partial class Form1 : Form
{
Timer t;
MouseButtons LastMouseButtonClicked;
Label lblStatus;
DateTime previousTick;
TimeSpan elapsed;
public Form1()
{
InitializeComponent();
lblStatus = new Label()
{
Text = "No click since tick."
,
Width = 1000
};
this.Controls.Add(lblStatus);
t = new Timer();
//A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond, or 10 million ticks in a second.
//t.Interval = (int)(100 / TimeSpan.TicksPerMillisecond);//0.01 ms
t.Interval = 1000;
t.Tick += T_Tick;
t.Enabled = true;
this.MouseClick += Form1_MouseClick;
elapsed = TimeSpan.Zero;
}
private void T_Tick(object sender, EventArgs e)
{
if (elapsed == TimeSpan.Zero)
{
elapsed += new TimeSpan(0, 0, 0, 0, 1);
}
else
{
elapsed += DateTime.Now - previousTick;
}
switch (LastMouseButtonClicked)
{
case MouseButtons.Left:
//Action...
lblStatus.Text = "MouseButtons.Left " + elapsed.Seconds;
break;
case MouseButtons.Right:
//Action...
lblStatus.Text = "MouseButtons.Right " + elapsed.Seconds;
break;
default:
lblStatus.Text = "No click since tick. " + elapsed.Seconds;
break;
}
previousTick = DateTime.Now;
}
private void Form1_MouseClick(object sender, MouseEventArgs e)
{
switch (e.Button)
{
case MouseButtons.Left:
LastMouseButtonClicked = e.Button;
t.Interval = 1000;
break;
case MouseButtons.Right:
LastMouseButtonClicked = e.Button;
t.Interval = 3000;
break;
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
If you are really really lazy and don't want to read the answer in my comment or redo the logic, you can perhaps modify your code like this (if this was your intent all along):
private void timer1_Tick(object sender, EventArgs e)
{
if (MouseButtons == MouseButtons.Left)
{
//Action...
}
if (MouseButtons == MouseButtons.Right)
{
//Action...
}
}
MouseButtons as in Control.MouseButtons
This is the method that is used to get the mouse button state within a timer_tick, with no need for a mouse click event, as per your request.
UPDATE Could you please mention what kind of timer are you using? They all have different behaviours and gotchas.
System.Windows.Forms.Timer, System.Timers.Timer and System.Threading.Timer.
I ask because sometimes there is an AutoReset property that you should set to true if you want more than one timer_tick to occur. I could be wrong, but this sounds like what you are describing, so it's worth a shot!
#Soenhay: I suspect that OP wanted to "loop and execute actions every t ticks" WHILE the mouse is held down. a.f.a.i.k. MouseClick triggers after MouseUp. You could modify the code to use MouseButtons (the static WinForms oddity) to check the state of the buttons.
#OP: Without you posting additional code, there is no way I see for anyone to help you further other than taking stabs in the dark with random code. Right now you have at least 3 examples similar to what you need, new knowledge about the static MouseButtons class, so I think you can and should take it from here or else you learn nothing!
I need to show a message after 10 seconds of form load.
I am using the below code
private void Form1_Load(object sender, EventArgs e)
{
SetTimeInterval();
}
System.Windows.Forms.Timer MyTimer = new System.Windows.Forms.Timer();
public void SetTimeInterval()
{
MyTimer.Interval = ( 10 * 1000);
MyTimer.Tick += new EventHandler(TimerEventProcessor);
MyTimer.Start();
}
void TimerEventProcessor(Object myObject,EventArgs myEventArgs)
{
MessageBox.Show("TIME UP");
MyTimer.Stop();
MyTimer.Enabled = false;
}
Tried using MyTimer.Stop() and MyTimer.Enabled = false, but messagebox keeps displaying every 10 seconds. How do I stop it after the first instance?
Your problem is that MessageBox.Show() is a blocking call. So MyTimer.Stop() is only called after you close the MessageBox.
So until you closed the MessageBox there will pop up new ones every 10s. The simple solution is to change the order of calls:
void TimerEventProcessor(Object myObject,EventArgs myEventArgs)
{
MyTimer.Stop();
MyTimer.Enabled = false;
MessageBox.Show("TIME UP");
}
So the timer is stopped as soon as you enter the event handler, before displaying the message box.
i would suggest this method
go to theform.designer.cs
writhe this code
this.timer1.Enabled = true;
this.timer1.Interval = 10000;
and do this in ur .cs file
private void timer1_Tick(object sender, EventArgs e)
{
MessageBox.Show("msg");
}
that work perfectly for me.
I have four buttons that are called "ship1,ship2" etc.
I want them to move to the right side of the form (at the same speed and starting at the same time), and every time I click in one "ship", all the ships should stop.
I know that I need to use a timer (I have the code written that uses threading, but it gives me troubles when stopping the ships.) I don't know how to use timers.
I tried to read the timer info in MDSN but I didn't understand it.
So u can help me?
HERES the code using threading.
I don't want to use it. I need to use a TIMER! (I posted it here because it doesnt give me to post without any code
private bool flag = false;
Thread thr;
public Form1()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
flag = false;
thr = new Thread(Go);
thr.Start();
}
private delegate void moveBd(Button btn);
void moveButton(Button btn)
{
int x = btn.Location.X;
int y = btn.Location.Y;
btn.Location = new Point(x + 1, y);
}
private void Go()
{
while (((ship1.Location.X + ship1.Size.Width) < this.Size.Width)&&(flag==false))
{
Invoke(new moveBd(moveButton), ship1);
Thread.Sleep(10);
}
MessageBox.Show("U LOOSE");
}
private void button1_Click(object sender, EventArgs e)
{
flag = true;
}
Have you googled Windows.Forms.Timer?
You can start a timer via:
Timer timer = new Timer();
timer.Interval = 1000; //one second
timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
timer.Enabled = true;
timer.Start();
You'll need an event handler to handle the Elapsed event which is where you'll put the code to handle moving the 'Button':
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
MoveButton();
}
Here the below code enables the particular bit as high in parallel port.How to set time interval for the button click in windows form.If i set the time interval to 2 seconds the timer should start then 2 seconds after that it should stop automatically.
private void button1_Click(object sender, EventArgs e)
{
PortAccess.Output(888,1);
}
can u please let me know any suggestion or example to do this.Inside this button_click.
So you just want to clear the bit 2 seconds later? Something like this should work:
private void button1_Click(object sender, EventArgs e)
{
// Prevent multiple button clicks
button.Enabled = false;
PortAccess.Output(888, 1);
Timer timer = new Timer { Interval = 2000 };
timer.Tick += HandleTimerTick;
timer.Start();
}
private void HandleTimerTick(object sender, EventArgs e)
{
Timer timer = (Timer) sender;
timer.Stop();
timer.Dispose();
button.Enabled = true;
PortAccess.Output(888, 0);
}
You may find it simpler to set up the timer just once, and store it as an instance variable. Then you could attach the Tick event and set the interval on construction, and add it to the components of the form so that it's automatically disposed. Your methods would then be:
private void button1_Click(object sender, EventArgs e)
{
button.Enabled = false;
PortAccess.Output(888, 1);
timer.Start();
}
private void HandleTimerTick(object sender, EventArgs e)
{
timer.Stop();
button.Enabled = true;
PortAccess.Output(888, 0);
}
I'm sure this has been asked before, but I cannot seem to find a solution that works. I have a NumericUpDown on my form and a label along with a timer and a button. I want the timer to start when the button is pressed and the interval for the timer to equal that of the NumericUpDown and a countdown will be displayed in the label. I know this should be easy. Any help?
So far:
int tik = Convert.ToInt32(TimerInterval.Value);
if (tik >= 0)
{
TimerCount.Text = (tik--).ToString();
}
else
{
TimerCount.Text = "Out of Time";
}
It doesn't seem to update as the timer ticks.
Here is a quick example to what you are looking for. This should give you a basic idea on what you need to do
//class variable
private int totNumOfSec;
//set the event for the tick
//and the interval each second
timer1.Tick += new EventHandler(timer1_Tick);
timer1.Interval = 1000;
private void button1_Click(object sender, EventArgs e)
{
totNumOfSec = (int)this.numericUpDown1.Value;
timer1.Start();
}
void timer1_Tick(object sender, EventArgs e)
{
//check the timer tick
totNumOfSec--;
if (totNumOfSec == 0)
{
//do capture
MessageBox.Show("Captured");
timer1.Stop();
}
else
label1.Text = "Caputring in " + totNumOfSec.ToString();
}
