Is there any way to run the application on the background even if the application/form is closed. All i can do now is just minimize it.
private void Form2_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Normal)
{
Hide();
WindowState = FormWindowState.Minimized;
}
else if (FormWindowState.Normal == this.WindowState)
{
Show();
}
}
If your application (your process) is closed, the notify icon will disappear. There is no way to avoid that.
So what you probably want is to keep your application running even if the user closes your Form. One way to achieve this is to actually not close the form but just hide it.
Therefor you need to subscribe to the Closing event of the Form:
public class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.Closing += Form1_Closing;
}
}
and implement the event handler like this:
void Form1_Closing(object sender, FormClosingEventArgs e)
{
Hide();
e.Cancel = true;
}
By setting e.Cancel = true you tell the form not to close. So you are just hiding it.
You'll need to add some code to your notify icon to reopen (Show()) the form again.

I cannot work out where to put nor get the code to trigger when my main form windows are resized (ie minimize button clicked)
I am trying to trigger this code when ANY resize of the DigiDocketMain window is minimized etc, or also how I can specifically code the minimize button to do something - the ideal goal is to get the program - n minimize button click to hide the taskbar icon and show a tray icon.
I have tried placing this is the main code body and the designer code but nothing triggers it. any help would be appreciated.
private void DigiDocketMain_Resize(object sender, System.EventArgs e)
{
MessageBox.Show("You are in the Form.ResizeEnd event.");
if (this.WindowState == System.Windows.Forms.FormWindowState.Minimized)
{
this.Hide();
mainTrayIcon.Visible = true;
}
}
In your code behind add the following to the Form_Load Event
this.SizeChanged += Form1_SizeChanged;
Then implement the function, autocomplete may do this for you.
private void Form1_SizeChanged(object sender, EventArgs e)
{
// Add the code that will be called on resize events.
}
According to your description, when clicking the minimize button, you want to hide the
taskbar icon and display the tray icon.
I suggest that you set the Visible of notifyIcon1 to false in the property bar, and select a icon format image as the icon, then try the following code.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Deactivate(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.notifyIcon1.Visible = true;
this.Hide();
this.ShowInTaskbar = false;
}
}
private void notifyIcon1_Click(object sender, EventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
this.ShowInTaskbar = true;
}
}
This question already has answers here:
How do I minimize a WinForms application to the notification area?
(4 answers)
Closed 9 years ago.
my app is for chatting, and i think if someone needs to hide it quick, but doesn't want to close it, i came up with this:
private void button6_Click(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Minimized;
}
however, instead of going to the taskbar, i want it to appear (no popup) in the tray, just the apps icon, and when someone clicks it it needs to set this
this.WindowState = FormWindowState.Normal;
Is this possible, how?
Also by system tray i mean the one in the bottom right corner, next to the time
I still can't get this to work, nothing appears in the notification bar if I do what you guys said (btw: this is the full code to minimise)
private void button6_Click(object sender, EventArgs e)
{
this.WindowState = FormWindowState.Minimized;
}
private void Form_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Minimized)
{
this.Hide();
}
}
private void notifyIcon_Click(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
}
Why isn't this working?
Handle the form’s Resize event. In this handler, you override the
basic functionality of the Resize event to make the form minimize to
the system tray and not to the taskbar. This can be done by doing the
following in your form’s Resize event handler:
Check whether the form’s WindowState property is set to FormWindowState.Minimized. If yes, hide your form, enable the NotifyIcon object, and show the balloon tip that shows some information.
Once the WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false.
Now, you want the window to reappear when you double click on the NotifyIcon object in the taskbar. For this, handle the NotifyIcon’s MouseDoubleClick event. Here, you show the form using the Show() method.
In the form resize event, do the check there and hide the form
private void Form_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Minimized)
{
this.Hide();
}
}
Then when clicking on the taskbar icon just restore it.
private void notifyIcon_Click(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
}
Refer:
How do I minimize a WinForms application to the notification area?
minimize app to system tray
Use following code:
if (WindowState == FormWindowState.Minimized)
{
this.Hide();
}
When you minimize the form, simply hide it.
You will have to implement above code in Form_Resize event.
Then on clicking taskbar icon just restore its state as follows:
private void notifyIcon_Click(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
}
You will need to use notifyIcon_Click event for this purpose.
Hope its helpful.
I overridden the FormClosing event to minimize to system tray when clicked. Here is my code:
private void OnFormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
this.Hide();
notifyIcon.BalloonTipText = "Server minimized.";
notifyIcon.ShowBalloonTip(3000);
}
else
{
this.Close();
}
}
And I also set the notifyIcon's DoubleClick event as well, here is the code:
private void showWindow(object sender, EventArgs e)
{
Show();
WindowState = FormWindowState.Normal;
}
I have two questions regarding this:
1) Now, when the upper-right "X" button is clicked, the application is minimized to the tray, but I can't close it (makes sense...). I wish to click right click on the icon in the system tray, and that it will open a menu with, let's say, these options: Restore, Maximize and Exit.
2) (This is may be related to me exiting the program with shift+f5 since I can't, for now, close my application because of the changes I mentioned).
When the application quits, after I minimzed it to the tray, the icon is left in the tray, until I pass over it with my mouse.
How can I fix it?
Just add a variable that indicates that the close was requested by the context menu. Say:
private bool CloseRequested;
private void exitToolStripMenuItem_Click(object sender, EventArgs e) {
CloseRequested = true;
this.Close();
}
protected override void OnFormClosing(FormClosingEventArgs e) {
base.OnFormClosing(e);
if (e.CloseReason == CloseReason.UserClosing && !CloseRequested) {
e.Cancel = true;
this.Hide();
}
}
Be sure to not call Close() in the FormClosing event handler, that can cause trouble when the Application class iterates the OpenForms collection. The possible reason that you are left with the ghost icon. No need to help.
I am developing a application using windows forms. The project contains 3 forms: one login form which is the main form and two others which are child forms to the login form.
My problem is when want to close the total application by using Application.Exit() in form closing event my messagebox showing the dialog more than once.
1.This code in Login form i.e main form:
private void FrmLogIn_FormClosing(object sender, FormClosingEventArgs e)
{
DialogResult loginResult = MessageBox.Show("Do you want to close this application?","Close",MessageBoxButtons.YesNo,MessageBoxIcon.Warning);
if (loginResult == DialogResult.Yes)
{
Application.Exit();
}
}
2.AdminForm closing event which is child form to login form:
private void FrmAdmin_FormClosing(object sender, FormClosingEventArgs e)
{
DialogResult loginResult = MessageBox.Show("Do you want to close this application?","Close",MessageBoxButtons.YesNo,MessageBoxIcon.Warning);
if (loginResult == DialogResult.Yes)
{
Application.Exit();
}
}
3.Billoperations form closing event which is child form to login form:
private void FrmBillOperation_FormClosing(object sender, FormClosingEventArgs e)
{
DialogResult loginResult = MessageBox.Show("Do you want to close this application?","Close",MessageBoxButtons.YesNo,MessageBoxIcon.Warning);
if (loginResult == DialogResult.Yes)
{
Application.Exit();
}
}
When i click the close button in any form it will show MessageBox message only once. Please help me.
Make all FormClosing methods call a ApplicationShutdown function which handles this in a central place. You don't want to copy this code to every new form you create.
In this method you can check a boolean (watch for thread-safety) called for example IsShuttingDown. If it's already true, leave the method, otherwise you ask the question and start exiting.
The FormClosingEventArgs instance passed to the FormClosing event has a CloseReason property, which will be set to CloseReason.ApplicationExit when the Exit method of the Application class has been invoked: your handlers should check for this condition and if so then take no further action.
private void FrmLogIn_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.ApplicationExit)
return;
...
}
You can try with this code
FormCollection fc = Application.OpenForms;
if (fc!= null && fc.Count > 0)
{
for (int i = 1; i < fc.Count; i++)
{
if (fc!= null && fc.IsDisposed!= true)
{
fc.Dispose();
}
}
}
private void sh_interface_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("This will close down the whole application. Confirm?", "Close Application", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
foreach (Form f in Application.OpenForms)
{
if (!f.IsDisposed)
f.Dispose();
}
}
else
{
e.Cancel = true;
this.Activate();
}
}
This will close all forms including the hidden forms and the main form from Application.Run(new something())...Also this method works when invoked in inherited classes while coded in template class Form Closing event.
I'm trying to implement some code that asks if the user wants to exit the application I've made.
It's in c# and is a windows form application.
I've had very little sleep this week and can't seem to get my head around the onFormClosing event. Could some please give me the exact code I should use to have code executed when the user clicks on the close button (the 'x' in the top right).
Please find it in your heart to help a sleep deprived moron.
Double-click the form's FormClosed event in the events tab of the Properties window in the designer.
The FormClosing event allows you to prevent the form from closing by setting e.Cancel = true.
Well, the event is called FormClosing and is cancellable. Subscribe to it, do your stuff and let the user close their form. This event is fired if the "x" button is used or if you close the form yourself.
You can subscribe to it in the designer by highlighting the form and looking in the events tab of the properties window, as SLaks says, then double-click it. You don't need to do anything special to cope with the "x" button.
The easiest way is to activate the form in the designer and find the event FormClosing in the properties windows and then just double click the event.
Then just do the following:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
var result = MessageBox.Show("Are you sure you want to exit?", "Exit", MessageBoxButtons.YesNo);
if (result != System.Windows.Forms.DialogResult.Yes)
{
e.Cancel = true;
}
}
}
If you do not specify that the reason has to be UserClosing, it will stop windows from shutting down if you do not exit the program first which is not a good practice.
public Form1()
{
InitializeComponent();
this.FormClosing += new FormClosingEventHandler(Form1_FormClosing);
}
void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("Are you sure that you wan't to close this app", "Question", MessageBoxButtons.OKCancel) == DialogResult.Cancel)
e.Cancel = true;
}
I hope this helps
You can add event handler manually. Example to add event handler in constructor:
public frmMain()
{
InitializeComponent();
FormClosing += frmMain_FormClosing;
}
private void frmMain_FormClosing(object sender, FormClosingEventArgs e)
{
//your code
}
Make derive your form fromf the System.Windows.Forms.Form and put this override:
protected override void OnFormClosing(CancelEventArgs e)
{
if (bWrongClose)
{
bWrongClose = false;
e.Cancel = true; // this blocks the `Form` from closing
}
base.OnFormClosing(e);
}
