Hi In my c# application I am trying to minimize application to systems tray, when the form is closed. Here is the code I have tried.
public void MinimizeToTray()
{
try
{
notifyIcon1.BalloonTipTitle = "Sample text";
notifyIcon1.BalloonTipText = "Form is minimized";
if (FormWindowState.Minimized == this.WindowState)
{
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(500);
this.Hide();
}
else if (FormWindowState.Normal == this.WindowState)
{
notifyIcon1.Visible = false;
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
and I am calling the method to form closing event. But the problem is its not minimizing to tray. Its just closing the form.
e.Cancel = true; code will be always cancelling the event even if you shut the computer down, but here is a code that helps you:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
myNotifyIcon.Visible = true;
this.Hide();
e.Cancel = true;
}
}
It will allow closing the form programmaticaly.
Write a event in Form Closing event.
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
Hide();
}
And write using Custom menu strip for notification icon for to show.
namespace MinimizeTrayNotification
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void MinimzedTray()
{
notifyIcon1.Visible = true;
notifyIcon1.Icon = SystemIcons.Application;
notifyIcon1.BalloonTipText = "Minimized";
notifyIcon1.BalloonTipTitle = "Your Application is Running in BackGround";
notifyIcon1.ShowBalloonTip(500);
}
private void MaxmizedFromTray()
{
notifyIcon1.Visible = true;
notifyIcon1.BalloonTipText = "Maximized";
notifyIcon1.BalloonTipTitle = "Application is Running in Foreground";
notifyIcon1.ShowBalloonTip(500);
}
private void Form1_Resize(object sender, EventArgs e)
{
if(FormWindowState.Minimized==this.WindowState)
{
MinimzedTray();
}
else if (FormWindowState.Normal == this.WindowState)
{
MaxmizedFromTray();
}
}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.WindowState = FormWindowState.Normal;
Form1 frm = new Form1();
frm.Show();
MaxmizedFromTray();
}
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
this.WindowState = FormWindowState.Normal;
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;
this.Hide();
}
}
private void notifyIcon1_Click(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Normal;
notifyIcon1.BalloonTipText = "Normal";
notifyIcon1.ShowBalloonTip(500);
}
}
}
You should cancel the FormClosing event and then call your MinimizeToTray() function.
This is done through the Cancel property of the FormClosingEventArgs.
Also, consider using a bool somewhere to allow closing the Form in some conditions, such as if you're using a File > Exit menu or something:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if(!allowClosing)
{
e.Cancel = true;
MinimizeToTray();
}
}
To minimize when closing set WindowState to Minimized
private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
e.Cancel = true;
WindowState = FormWindowState.Minimized;
}
You need to use the FormClosing-Event.
private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
e.Cancel = true;
MinimizeToTray();
}
You can handle FormClosing Event such as micsoft Form Closing Event as Following example of C#
private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
// Determine if text has changed in the textbox by comparing to original text.
if (textBox1.Text != strMyOriginalText)
{
// Display a MsgBox asking the user to save changes or abort.
if (MessageBox.Show("Do you want to save changes to your text?", "My Application",
MessageBoxButtons.YesNo) == DialogResult.Yes)
{
// Cancel the Closing event from closing the form.
e.Cancel = true;
// Call method to save file...
}
}
}

notify icon disappears after 2 or 3 seconds and i have to restart the application
I have tried this code but not working properly
private void Frm_Dashboard_Resize_1(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
Hide();
notifyIcon1.Visible = true;
}
}
private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
ShowInTaskbar = true;
notifyIcon1.Visible = false;
WindowState = FormWindowState.Normal;
}
You are not showing the form in the NotifyIcon double click event.
Change your code to -
private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
Show(); //display the form
this.WindowState = FormWindowState.Normal;
notifyIcon1.Visible = false;
}
Also, look at the Remarks section of the ShowBalloonTip method
i'm beginner. my form border style is none i want to restore it only one click which event should i use to restore it in one click..
my Code
private void New_Click(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.WindowState = FormWindowState.Normal;
}
}
You need to hook up (Register) the Form/controls Click event and perform whatever you want in the handler method. Like below
public Form1()
{
InitializeComponent();
this.Click +=new EventHandler(Form1_Click);
}
private void Form1_Click(object s, EventArgs e)
{
if (this.WindowState == FormWindowState.Maximized)
this.WindowState = FormWindowState.Normal;
}
so I have this code
public void Update_Click(object sender, EventArgs e)
{
using (PccBiometricsHandler.Form1 ShowProgress = new PccBiometricsHandler.Form1())
{
menu.Items[2].Enabled = false;
ShowProgress.ShowDialog();
ShowProgress.FormClosed += new FormClosedEventHandler(MyForm_FormClosed);
}
}
public void MyForm_FormClosed(object sender, FormClosedEventArgs e)
{
updaterAccess();
menu.Items[2].Enabled = true;
}
so after I click Update it will run the child form Form1
which is this:
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
notifyIcon1.Visible = true;
notifyIcon1.BalloonTipTitle = "Update Complete";
notifyIcon1.BalloonTipText = "Successfully Update";
notifyIcon1.ShowBalloonTip(500);
timer1.Interval = 4000;
timer1.Enabled = true;
timer1.Tick += new EventHandler(timer1_Tick);
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
notifyIcon1.Dispose();
this.Close();
}
so as you can see it runs on a backgroundworker with a timer to close the child Form1
now my problem is that after closing the Child Form1 it doesn't run the MyForm_FormClosed which it should enable menu.Items[2] again and updaterAccess()
I think I'm missing something in my mainForm
Attached the event handler before firing ShowDialog
public void Update_Click(object sender, EventArgs e)
{
using (PccBiometricsHandler.Form1 ShowProgress = new PccBiometricsHandler.Form1())
{
menu.Items[2].Enabled = false;
ShowProgress.FormClosed += new FormClosedEventHandler(MyForm_FormClosed); //Attached the event handler before firing ShowDialog
ShowProgress.ShowDialog();
}
}
ShowDialog synchronously shows a modal dialog, meaning it blocks until the form is closed (the following code is not run until the form is closed). Therefore, when ShowDialog returns the form is already closed.
You can attach the event handler before calling ShowDialog() as #Jade suggests, which will work, but honestly you do not need to use the event system at all. Simply wait for ShowDialog to return then perform the actions you would when the form is closed:
public void Update_Click(object sender, EventArgs e)
{
using (PccBiometricsHandler.Form1 ShowProgress = new PccBiometricsHandler.Form1())
{
menu.Items[2].Enabled = false;
ShowProgress.ShowDialog();
}
updaterAccess();
menu.Items[2].Enabled = true;
}
If you want to do this in VB:
AddHandler ShowProgress.FormClosed, AddressOf MyForm_FormClosed
I want to hide my application in system tray when I click the Form Closing button(clasic red X button). I provided with this code;
private void Ana_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
this.Hide();
}
So, the application is stil running in the system tray. I have added a ContextMenuStrip and when I right click on mouse ContextMenuStrip a Close button comes up but when I click that Close button the application is still running.
I want to terminate the application when I click that Close button. Here is my code:
private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
{
DialogResult ext;
ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (ext == DialogResult.Yes)
{
Application.Exit();
}
}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show();
}
Calling Application.Exit() will actually attempt to close all your forms, and because your FormClosing is hard coded to be cancelled, then it cannot complete the task.
One option with your current structure would be to create an AllowClose flag. This could be a property of the Form, or it could be a global static value.
For example:
//in your form
public bool AllowClose {get;set;}
private void Ana_FormClosing(object sender, FormClosingEventArgs e)
{
if(!AllowClose)
{
e.Cancel = true;
this.Hide();
}
}
//in your context menu event
private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
{
DialogResult ext;
ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (ext == DialogResult.Yes)
{
this.AllowClose = true;
Application.Exit();
}
}
Try this,
bool isClosing = false;
private void Ana_FormClosing(object sender, FormClosingEventArgs e)
{
if(!isClosing)
{
e.Cancel = true;
this.Hide();
}
}
private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
{
DialogResult ext;
isClosing = true;
ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (ext == DialogResult.Yes)
{
Application.Exit();
}
}
I am getting this error Collection was modified; enumeration operation may not execute.
I have 3 forms. These are the form closing events of all 3 I did some research and learnt that some from was modified/shown inturn causing this error
Form1
private void btnExitl_Click(object sender, EventArgs e)
{
this.Close();
}
private void frmPlant_FormClosing(object sender, FormClosingEventArgs e)
{
if (DataDirty)
{
if (DialogResult.Yes == MessageBox.Show("Are you sure you want to exit", "Data Changed", MessageBoxButtons.YesNo, MessageBoxIcon.Question))
Application.Exit();
else
e.Cancel = true;
}
else
Application.Exit();
}
Form2:
private void btnCancel_Click(object sender, EventArgs e)
{
this.Close();
}
private void frmInputFiles_FormClosing(object sender, FormClosingEventArgs e)
{
int plantid = StaticClass.GlobalValue;
//Properties.Settings.Default.PlantId = plantid;
Program.fPlant = new frmPlant(plantid);
Program.fPlant.Show();
e.Cancel = false;
//this.Hide();
}
Form3:
private void btnClose_Click(object sender, EventArgs e)
{
this.Close();
}
private void frmVesselData_FormClosing(object sender, FormClosingEventArgs e)
{
DialogResult result;
int fileId = StaticClass.FileGlobal;
if (DataDirty)
{
string messageBoxText = "You have unsaved data. Do you want to save the changes and exit the form?";
MessageBoxButtons button = MessageBoxButtons.YesNo;
string caption = "Data Changed";
MessageBoxIcon icon = MessageBoxIcon.Question;
result = MessageBox.Show(messageBoxText, caption, button, icon);
if (result == DialogResult.No)
{
Program.fInputFiles = new frmInputFiles(gPlantId, gPlantName);
Program.fInputFiles.Show();
//e.Cancel=true;
}
if (result == DialogResult.Yes)
{
e.Cancel = true;
//return;
}
}
else
{
Program.fInputFiles = new frmInputFiles(gPlantId, gPlantName);
Program.fInputFiles.Show();
//e.Cancel = false;
}
}
It happens only when I view the third form(Form3). Form1, Form2 work well,. But if I view form3 and try to go back to form1
So somewhere in the closing event of form3, form1
My guess is the btnExit_close event of the form this.close()
Thank you
Simply call Environment.Exit(0);
While closing your First Form try this on FormClosingEvent
private void frmPlant_FormClosing(object sender, FormClosingEventArgs e)
{
if (DataDirty)
{
if (DialogResult.Yes == MessageBox.Show("Are you sure you want to exit", "Data Changed", MessageBoxButtons.YesNo, MessageBoxIcon.Question))
{
this.Close();
Application.Exit();
}
else
e.Cancel = true;
}
else
Application.Exit();
}
Call this.Close() first and then Application.Exit(), Application.Exit() terminates all processes and Close() close your main form
