How can I make the (default) Close button (at top right corner) in my application, to work it as Minimize.
Actually I want to minimize the application on clicking the cross-symbol, but exit the application, when use clicks on my menu option Exit.
I wrote this code for minimizing the form on clicking close button:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (minimize_on_close == "Yes")
{
e.Cancel = true;
this.WindowState = FormWindowState.Minimized;
}
}
and wrote this code for exiting the application, on clicking exit from menu options.
private void exitToolStripMenuItem1_Click(object sender, EventArgs e)
{
Application.Exit();
}
But now, when I click on Exit menu option, then also the form is being minimized, and not exiting.
Can anyone please help?
Check to see whether FormClosingEventArgs.CloseReason is equal to CloseReason.UserClosing before deciding to minimize the window. Alternatively, compare for CloseReason.ApplicationExitCall.
From the documentation for CloseReason:
Members
...
UserClosing
The user is closing the form through the user interface (UI), for example by clicking the Close button on the form window, selecting Close from the window's control menu, or pressing ALT+F4.
...
ApplicationExitCall
The Exit method of the Application class was invoked.
Try this
EDIT
May use Resize Event to do it,
private void Form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
this.Hide();
}
Then using the FormClosing Event to cancel Close and minimize the Form as below
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
this.WindowState = FormWindowState.Minimized;
}
}

I'm working on a Win Forms project where I'm trying to create an button to toggle full screen on/off every time i click the button,so if you click once, it becomes full screen, if you click again, it becomes normal again.
please tell me how to do that.
I am not sure about the exact requirements but this should help you.
Add Form1_Load and button1_Click events.
private void Form1_Load(object sender, EventArgs e)
{
// Normal when the form opens
WindowState = FormWindowState.Normal;
}
private void button1_Click(object sender, EventArgs e)
{
// Toggle on a button click
WindowState = WindowState == FormWindowState.Normal ? FormWindowState.Maximized : FormWindowState.Normal;
}
My problem is, I am hiding my app in system tray when close event is fired,
User can resume it by double clicking on notify icon. Close event only works for the first time in my wpf app.
private void SparkWindow_Closing(object sender, CancelEventArgs e)
{
DialogResult dr = MessageBox.Show("Do you really want to close application?","Confirmation",MessageBoxButton.YesNo,MessageBoxIcon.Question);
if(dr==DialogResult.No)
{
e.Cancel = true;
this.Hide();
notifyIcon.Visibility = System.Windows.Visibility.Visible;
}
else
{
Application.Current.ShutDown();
}
}
this is how i handle the closing event.
and below given code is used to bring it back in front of from system tray.
private void OnNotifyIconDoubleClick(object sender, MouseButtonEventArgs e)
{
if (e.ChangedButton == MouseButton.Left)
{
this.Show();
this.WindowState = this.lastWindowState;
this.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen;
}
}
but when it resumes it doesn't fire the closing event 2nd time.
I am trying to make my application minimize to task bar/tray
Here is my code so far that I have pulled together from other SO posts and other people seem to have it working but my app minimizes to the tray but when I click it in the tray it doesn't reopen.
private void Form1_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Minimized)
{
this.notifyIcon1.Visible = true;
this.notifyIcon1.ShowBalloonTip(500);
this.Hide();
}
}
private void notifyIcon1_DoubleClick(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
}
just to explain again the problem is the application minimizes to the tray but when I click on the icon it doesn't restore the app to normal. Instead it does nothing.
I found my problem.
what I didn't do was this
Set the NotifyIcon's visible property to false in the property editor. Now go to the property editor of Form1, click on the little lightning symbol to access the events, and double click on the Resize event, and change the code to:
and I also didn't do this
Finally we need the code to make the program show up again when the icon is double clicked. So double click on NotifyIcon1 in the designer,
I found this information here

This is what I have used in the past but I fund a copy online at the link below
if (FormWindowState.Minimized == this.WindowState)
{
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(500);
this.Hide();
}

I have a form which contains a close button (there are many control in the form, but I am concerning about the close event) and a save button.
If a form have value in certain text box (say TextBox1),
Then I want to validate that the save button is clicked before closing the form (whether close button or the 'X' button at top is pressed).
But if there is no value in that text box or the form is just initialized and user just want to close the form, it simply closes the form. How to perform this validation.
I would follow the pattern of 99% of windows applications: allow to close a window, but ask to save changes if there are any. Here is a simple implementation of that pattern:
private bool _hasChanges;
private void textBox1_TextChanged(object sender, EventArgs e)
{
this._hasChanges = true;
}
private void form_FormClosing(object sender, FormClosingEventArgs e)
{
if (this._hasChanges)
{
var dialogResult = MessageBox.Show("Save changes?", "Confirm", MessageBoxButtons.YesNoCancel);
switch (dialogResult)
{
case DialogResult.Yes:
this.Save();
break;
case DialogResult.No:
this._hasChanges = false;
break;
}
e.Cancel = this._hasChanges;
}
}
private void Save()
{
// Save
this._hasChanges = false;
}
private void buttonSave_Click(object sender, EventArgs e)
{
this.Save();
}
private void buttonOk_Click(object sender, EventArgs e)
{
this.Close();
}
private void buttonCancel_Click(object sender, EventArgs e)
{
this._hasChanges = false;
this.Close();
}
The pivotal part is the boolean _hasChanges. If there are many controls that can cause changes this can be real pain. An alternative could be to use databinding to a class that implements INotifyPropertyChanged and subscribe to its PropertyChanged event.
Tie into the Closing Event and use your EventHandler to validate that textbox. Keep in mind that Closing occurs at the time the form is closing and (if memory servers correctly) there is a property on the eventarg that will let you cancel closing of the form. This event is raised regardless of how the request is executed.
A simple question again.
I am using a window in a WPF as a child window, where I would rather have the 'X' button hide the window instead of close. For that, I have:
private void Window_Closing(object sender, CancelEventArgs e) {
this.Hide();
e.Cancel = true;
}
The problem is that when the parent window is closed, this never closes and keeps the app alive.
Is there a clean way to deal with this? I thought of adding a Kill flag to all my user controls (windows):
public bool KillMe;
private void Window_Loaded(object sender, RoutedEventArgs e){
KillMe = false;
}
private void Window_Closing(object sender, CancelEventArgs e) {
this.Hide();
if (!KillMe) e.Cancel = true;
}
Then in MainWindow_Closing() I would have to set all window KillMe flags to true.
Any better way than creating additional flags and forgetting to set them before closing?
You could call Shutdown in the "parent's" closing handler... This will cause your Cancel to be ignored.
From Window.Closing:
If Shutdown is called, the Closing event for each window is raised. However, if Closing is canceled, cancellation is ignored.
I usualy have my own AppGeneral static class for such cases. When I'm realy exiting app I'm setting AppGeneral.IsClosing static bool to true. And then, when closing:
private void Window_Closing(object sender, CancelEventArgs e) {
if (!AppGeneral.IsClosing)
{
this.Hide();
e.Cancel = true;
}
}
Also, you can kill the your own process (that's ugly but working :) ) Process.GetCurrentProcess().Kill();
You should use
Application.Current.Shutdown();
inside your master window closing method.
This should override canceling of any subwindow!
