C# Timer Start and Stop - c#

I did a button, and when u click on the button, it will start the Timer1.Start();
And when u click again on the same button, it will stop the Timer1.Stop();
I tried
private void button1_Click(object sender, EventArgs e)
{
timer1.Start();
else
{
timer1.Stop();
}
}
And the code above is not working, i get always error.
So if i click on the button, timer will run, if i click again on the same button, timer will stop.

You should do it like this:
private void button1_Click(object sender, EventArgs e)
{
ToggleTimer();
}
private void ToggleTimer()
{
!timer1.Enabled ? timer1.Start() : timer1.Stop();
timer1.Enabled = !timer1.Enabled;
}
ToggleTimer() will first check whether the timer has been disabled, and if so, it will either start the timer and mark it as enabled, or stop it and mark it as disabled.

Title show while timer is enabled

so I have a problem where I want to make a label pop up when timer is enabled. I tried writing this but it just doesn't work. I have set every object property as needed, but still there is some kind of problem. Can you help me please? Thanks.
private void timer1_Tick(object sender, EventArgs e)
{
if (button3Click == true && FullNameBOX.Text == "")
{
timer1.Start();
while(timer1.Enabled == true)
{
label5.Show();
}
timer1.Stop();
}
else if(timer1.Enabled == false)
{
label5.Hide();
}
else
{
}
timer1_Tick is only executed once the timer is started and the timer interval is elapsed for the first time and then repeatedly every interval. So you must start the timer somewhere else. In button button3_Click I assume
private void button3_Click(object sender, EventArgs e)
{
if (FullNameBOX.Text == "")
{
label5.Show();
timer1.Start();
}
else
{
... process the FullNameBOX.Text
}
}
In the Tick event handler stop the timer and hide the label
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Stop();
label5.Hide();
}
Also, give better names to your controls. It's best to do so before creating the event handlers so that those get better names too. It is easier to understand messageLabel than label5 and SaveButton_Click than button3_Click.

button click every interval c#

I have a button where I want to it to click every 5 seconds.
I also have another button where the first button will stop clicking.
This is the code so far I have
private void StartButton_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
Timer timer = new Timer { Interval = 5000 };
timer.Start();
}
How do I go on about achieving this?
if the button will set timer start/stop called 'ControlButton', and another one called 'DoJobButton'. Setup a timer interval = 5000 like your code. and in's tick event have this code only
DoJobButton.PerformClick();
this will trigger DoJobButton button's click action.
and set timer enable/disable in ControlButton's click event.
I think this is enough for your goal.

c# timer preventing button click

I am currently trying to create a hover effect on a custom control, where a panel (panel1) shows up after the mouse enters the control.
I have a timer that starts when the mouseleave event is raised, the interval is 250ms, and there is an onTick event that changes the visibility of the panel1 to false.
This all works. However, the buttons on panel1 do not always respond when clicked.
Here is the pertinent code - I will supply anything else that is required if I'm missing some information.
private void MagicCardViewer_MouseLeave(object sender, EventArgs e)
{
timer1.Start();
timer1.Interval = 250;
timer1.Tick += new EventHandler(timer1_TickOff);
timer1.Tick -= timer1_TickOn;
}
private void MagicCardViewer_MouseEnter(object sender, EventArgs e)
{
showPanel1();
}
public void showPanel1()
{
//show necessary controls
buttonDiscard.Show();
//show panel1
panel1.Visible = true;
ActiveControl = panel1;
}
public void hidePanel1()
{
panel1.Visible = false;
//hide controls
}
# region button events
private void buttonChoose_Click(object sender, EventArgs e)
{
Chosen = !Chosen;
if (Chosen)
{
callCardChosen();
}
}
private void buttonTap_Click(object sender, EventArgs e)
{
cards[0].ChangeTap();
DrawCardTap();
onCardChanged();
}
private void buttonActivate_Click(object sender, EventArgs e)
{
cards[0].TryActivate(0);
}
private void buttonDiscard_Click(object sender, EventArgs e)
{
cards[0].onDiscard();
}
# endregion
I think that is everything, but there is a lot of code to select from.
breakpoints don't trigger, the button flashes but nothing happens. If the timer interval is set very long, it works fine, but the point is for the button to vanish quickly once the mouse leaves the control. If the mouse is on the buttons, then the form reports it as having left the control.
To sum up - the buttons are not always processing when I click on them.
If you have the timer ticking every 250ms that could prevent the event on the mouse click.
I would check that you stop the timer after the tick if you no longer need it, and restart as I think you are doing when the user leaves the control or enter it again.
This could be why it works when you set a longer time interval.

How to perform Label click in C#?

I have a label working as a button. I would like when I press a button the click event to this label to take action. for example
private void Label1_Click(object sender, EventArgs e)
{
MessageBox.Show("I pressed this label and showed me this messagebox");
}
Now I want when I press this button, the label1 click event to be performed
private void button1_Click(object sender, EventArgs e)
{
// I want when I press this button something like this happens
Label1.PerformClick();
}
private void button1_Click(object sender, EventArgs e)
{
Label1_Click(sender, e);
}
now if you want to show a message of which control was clicked all in one method do the following
private void label1_Click(object sender, EventArgs e)
{
Control control = (Control)sender;
var name = control.Name;
MessageBox.Show(string.Format("I pressed this {0} and showed me this messagebox",name));
}
Two ways to do this.
First:
private void button1_Click(object sender, EventArgs e)
{
Label1_Click(sender, e); // Just call the Label's click handler
}
Second:
// Bind the Label1_Click handler to the button1 Click event, as they both use the same delegate
button1.Click += new EventHandler(Label1_Click);
With the second approach, note that in C# delegates are multi-cast, so both the button1_Click handler and the Label1_Click handler will be called when the button is clicked, in the order they were bound.
private void button1_Click(object sender, EventArgs e)
{
//What the label click do:
MessageBox.Show("I pressed this label and showed me this messagebox");
}
Is that not easier?
Why do you want to do it ?
I think it would be easier for you to just include the lable click functionality with the button click. Maybe even separate each piece in their own method and call them from the button click. Here is how you'd call another click event.
private void button1_Click(object sender, EventArgs e)
{
label1_Click(sender, e);
}
public class MyLabel:Label
{
public void PerformClick()
{
OnClick(new EventArgs());//InvokeOnClick(this,new EventArgs());
}
}

C# mousedown event continously press key

okay so what I want to do, it when the mouse is HELD DOWN I want it to continously press a key. it should continously press this key until I let off.
Imagine if you will, a left and right button on a windows form,
then by clicking and holding the right button, the letter "R" displays on a textbox continously until you release the button. What I am doing has very little to do with that scenario, but you get what I'm trying to do here.
What exactly do I put in the mouse down to keep the sendkeys going forever without locking up the application?
I hope my question makes sense. lol.
Thanks
RT
private void pictureBoxKeyboard_MouseDown(object sender, MouseEventArgs e)
{
//something goes here
}
This is worth a read...

SendKeys.Send("r")
This might just fire once, you may want to attach a timer that starts on the MouseDown event and stops on the MouseUp event. Then you could put the SendKeys in the Timer.Tick event.
private void Form1_Load(object sender, EventArgs e)
{
this.timer1.Interval = 500;
}
private void button1_MouseUp(object sender, MouseEventArgs e)
{
timer1.Stop();
this.Text = "moose-Up";
}
private void button1_MouseDown(object sender, EventArgs e)
{
timer1.Start();
this.Text = "moose-Down";
this.richTextBox1.Select();
}
private void timer1_Tick(object sender, EventArgs e)
{
SendKeys.Send("r");
Debug.Print("tickling");
}
Select the control that you wish to receive the SendKeys value...
