I have to show one form for about 5 sec and then I have to close that form and then show some other form once the new form is shown the timer has to stop.
I have difficulty in doing this.
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
Form5 f5 = new Form5();
f5.Show();
f5.label7.Text = label6.Text;
MyTimer.Interval = 5000; // 0.5 mins
MyTimer.Tick += new EventHandler(MyTimer_Tick);
MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
MessageBox.Show("All The Best for Your Test and Your Time Starts Now.");
Form6 f6 = new Form6();
f6.Show();
MyTimer.Enabled = false;
Form5 f5 = new Form5();
f5.Hide();
}
try this code
Form5 f5 = new Form5();
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
f5.Show();
f5.label7.Text = label6.Text;
MyTimer.Interval = 5000; // 0.5 mins
MyTimer.Tick += new EventHandler(MyTimer_Tick);
MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
MessageBox.Show("All The Best for Your Test and Your Time Starts Now.");
Form6 f6 = new Form6();
f6.Show();
MyTimer.Enabled = false;
MyTimer.stop();
f5.Hide();
}
Pull the declaration of Form5 outside of the functions, so it is a field. As it stands, each function has a different instance of this class.
Form5 f5 = new Form5();
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
f5.Show();
f5.label7.Text = label6.Text;
MyTimer.Interval = 5000; // 0.5 mins
MyTimer.Tick += new EventHandler(MyTimer_Tick);
MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
MessageBox.Show("All The Best for Your Test and Your Time Starts Now.");
Form6 f6 = new Form6();
f6.Show();
MyTimer.Enabled = false;
MyTimer.Stop();
f5.Hide();
}
Note: You really should rename your form classes and the variables - f6 is meaningless. Call it what it is.
try this
Form5 f5 = new Form5(); //declare form obj globally
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
f5.Show();
f5.label7.Text = label6.Text;
MyTimer.Interval = 5000; // 0.5 mins
MyTimer.Tick += new EventHandler(MyTimer_Tick);
MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
MessageBox.Show("All The Best for Your Test and Your Time Starts Now.");
Form6 f6 = new Form6();
f6.Show();
MyTimer.Enabled = false;
f5.Hide();
}
I see several potential problems. First, you should setup your timer only once, perhaps at Form construction time, you don't need to set the interval and wire up an even handler every single time radioButton1's check state changes.
Inside of MyTimer_Tick, the first line should be calling MyTimer.Stop() (just call stop, you don't need to mess with Enabled, they do the same thing).
THEN you can display the MessageBox (which is modal and blocking), show Form6, hide f5, etc.
Think of MessageBox.Show() as a really long running call. It doesn't return until the message box is dismissed (it can easily take more than 5 seconds or any arbitrary amount of time). While the MessageBox is up, timer tick events are still queuing up (because the line that stops the timer hasn't been executed yet). It would be worth looking up the documentation for MessageBox.Show() and reading about what a modal dialog is and how its different from the alternative.
And try and clean up the names as other's have pointed out.
I think You're making it to difficult. If I understood You correctly...
Just add a timer to form5, set it's properties Enabled = true; and Interavl = 1000; (1000 miliseconds or 1 second). and just add timer tick event handler to your form5 timer like
private int _start = 0;
private int _seconds = 5;
private void timer1_Tick(object sender, EventArgs e)
{
_start++;
if(_start >= _seconds)
{
Close();
}
}
_start and _seconds should be initialized like form class private fields, or properties before event handler. This code works fine for me, and it closes form5 after 5 seconds it was shown. If you want to make this more flexible, for example if you want to set how many seconds form5 should be shown U can, for example, reload form5 constructor like ...
public Form5(int seconds)
{
InitializeComponent();
_seconds = seconds;
}
and in form1, when you create form5 pass number of seconds U want to show form5 as parameter:
Form5 f5 = new Form5(5);
also I think it would be better to create new instance of form 5 dirrectly in event handler
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
new Form5(10).Show(); // show form5 for 10 seconds
...
}
If U want to show some another more form after form5 close, just show it before form5 close in timer tick event handler:
private void timer1_Tick(object sender, EventArgs e)
{
_start++;
if(_start >= _seconds)
{
new Form2().Show();
Close();
}
}

I have the following code but it is not executing for the TimeOut object for inactivity
private void Form1_Load(object sender, EventArgs e)
{
Console.WriteLine("booting up....");
programController.init(this);
disableFetchSetData();
label3.Hide();
logoutButton.Hide();
//Added Timer Object to log out of program
Timer MyTimer = new Timer();
MyTimer.Interval = (10 * 60 * 1000); // 10 mins
MyTimer.Tick += new EventHandler(TimeOut);
MyTimer.Start();
}
public void TimeOut(object sender, EventArgs e)
{
MessageBox.Show("The form will now close due to inactivity");
this.Close();
}
Why is this? It is supposed to execute from the Load() of the Form. Since the TimeOut method is an event, it is called upon the Load of the Form.
I use this code to refresh my from it work good for one time after that the timer stopped with me
private void Button1_Click(object sender, EventArgs e)
{
System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();
timer1.Interval = 900000;//5 minutes
timer1.Tick += new System.EventHandler(Timer1_Tick);
timer1.Start();
}
private void Timer1_Tick(object sender, EventArgs e)
{
//do whatever you want
RefreshMyForm();
}
private void RefreshMyForm()
{
this.Hide();
Graph1 graph = new Graph1();
graph.Show();
}
i don't know what i miss in this code
it hide the from and didn't open again
start refresh that what i looking form
You need to move the timer deceleration out of the button click and make it "global" to the class. Also, set it up on the Form_Load (make sure you wire up the Form_Load method to your Form_Load event.
Also, your hide logic is a bit faulty. You hide the form, then create a graph (but don't attach it to the Form) then show it. Added some comments below to help you navigate these issues.
private System.Windows.Forms.Timer timer1;
private void Form_Load(object sender, EventArgs e)
{
timer1 = new System.Windows.Forms.Timer();
timer1.Interval = 900000;//5 minutes
timer1.Tick += new System.EventHandler(Timer1_Tick);
}
private void Button1_Click(object sender, EventArgs e)
{
if (!timer1.Enabled)
timer1.Start();
}
private void Timer1_Tick(object sender, EventArgs e)
{
//do whatever you want
RefreshMyForm();
}
private void RefreshMyForm()
{
// Do your data update logic here
this.Refresh();
}
I have a dll that has a timer control in it, inside I have a message box. The timer has been enabled and the interval has been set to 100 seconds, but for some reason it's not firing. I added button to check if it's enabled, and timer1.enabled property is set to true, but it doesn't fire even once. Any ideas what could be wrong? Thanks!
Dll Code:
private void timer1_Tick(object sender, EventArgs e)
{
MessageBox.Show("Test");
}
This is how I call the dll form:
M.ModuleInterface module = Activator.CreateInstance(t) as M.ModuleInterface;
Thread t = new Thread(module.showForm);
t.Start();
showForm Method:
void M.ModuleInterface.showForm()
{
log("GUI::Initialized()");
frm.ShowDialog();
}
i believe, judging by your words alone, that you simply forgot to register to the time.
do:
public Form1()
{
InitializeComponent();
this.timer1.Tick += new System.EventHandler(this.timer1_Tick);
}
private void timer1_Tick(object sender, EventArgs e)
{
// Your code here
}
this little example works just fine:
private System.Windows.Forms.Timer timer1;
public Form1()
{
InitializeComponent();
timer1 = new System.Windows.Forms.Timer();
timer1.Interval = 100;
this.timer1.Tick += new System.EventHandler(this.timer1_Tick);
timer1.Enabled = true;
}
private void Form1_Load(object sender, EventArgs e)
{
// timer is triggered. code here is called
}
I created a simple C# app that uses the beep console. I want to add a stop button to stop the beeping, but once the app starts to run it doesnt let me hit a close/button button. Below is the code i have.
private void button1_Click(object sender, EventArgs e)
{
int int1, int2, hours;
int1 = int.Parse(txtbox1.Text);
int2 = int.Parse(txtbox2.Text);
hours = ((60 / int1) * int2);
for (int i = 0; i <= hours; i++)
{
Console.Beep();
Thread.Sleep(int1 * 60000);
}
}
The reason is that you execute button1_Click in the GUI thread. When you call this method the thread will be stuck there for quite some time because you make it sleep.
If you remove Thread.Sleep(int1*60000); you will notice that your application is unresponsive until it is done beeping.
You should try to use a Timer instead. Something like this should work (this is based on the Windows.Forms.Timer):
private Timer timer = new Timer();
And set it up
timer.Tick += OnTick;
timer.Interval = int1 * 60000;
...
private void OnTick(object o, EventArgs e)
{
Console.Beep();
}
In your buttonclick you are now able to start and stop the timer:
timer.Start();
or
timer.Stop();
I would use a timer in this case, the reason why you can't close the form is because you are calling a sleep on the form thread from what I understand. Calling a sleep on the form thread will give the impression the app has crashed.
Here is a quick sample code I built in c#, it will beep the console at the time given. I hope it helps.
private void button1_Click(object sender, EventArgs e)
{
timer1.Tick += new EventHandler(timer_dosomething);
timer1.Interval = 60000;
timer1.Enabled = true;
timer1.Start();
}
private void button2_Click(object sender, EventArgs e)
{
timer1.Stop();
}
void timer_dosomething(object sender, EventArgs e)
{
Console.Beep();
}
Could any one help me to stop my timer in windows form C3 application? I added timer in form using designer and interval is set as 1000; I would like to do some actions after 5 seconds of waiting after button click. Please check the code and advise me. Problem now is I get MessageBox2 infinitely and never gets the timer stop.
static int count;
public Form1()
{
InitializeComponent();
timer1.Tick += timer1_Tick;
}
public void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
while(count>5)
{
....dosome actions...
}
}
private void timer1_Tick(object sender, EventArgs e)
{
count1++;
MessageBox.Show("Messagebox2");
if (count1 == 5)
{
//timer1.Enabled = false; timer1.Stop();
((System.Timers.Timer)sender).Enabled = false;
MessageBox.Show("stopping timer");
}
}
I would render the count useless and just use the timer 1 interval property and put your actions in the timer1_Tick event.
public void button1_Click(object sender, EventArgs e)
{
timer1.Interval = 5000;
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
MessageBox.Show("stopping timer");
// Your other actions here
}
You are incrementing count1 and checking count.
while(count1 > 5)
{
...dosome actions...
}
Which Timer do you use? Because C# supports class Timer from two different namespaces. One is from Forms, the other is from System.Timers. I would suggest you to use the other one - System.Timers.Timer.
Timer t = new Timer(20000); // created with 20seconds
t.Enabled = true; // enables firing Elapsed event
t.Elapsed += (s, e) => {
\\do stuff
};
t.Start();
In this short code you can see how the timer is created and enabled. By registering to the Elapsed event you explicitly say what to do after the time elapses. and this is done just once. Of course, there are some changes needed in case user clicks button before your limit is reached. But this is highly dependent on behavior of the action you demand.
