How can I have my application minimize itself to the system tray in WindowsXP/Vista?
I'm also looking for a way to have a message display itself when the mouse is hovered on the icon. Is it possible to have two lines in the pop up balloon?
I assume you mean minimize to the System tray because you have talked about icons and message ballons?
The following code will set up a tray icon:
private void SetUpTrayIcon()
{
notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.BalloonTipText = "Ballon minimize text";
notifyIcon.BalloonTipTitle = "Ballon minimize title";
notifyIcon.Text = "Icon hover text";
notifyIcon.Icon = new System.Drawing.Icon(
System.Reflection.Assembly.GetExecutingAssembly()
.GetManifestResourceStream("MyIcon.ico"));
notifyIcon.Click += new EventHandler(HandlerToMaximiseOnClick);
}
To show the icon in the tray (you may want to do this on the window state change event for example, do something like the following:
if (notifyIcon != null)
{
notifyIcon.Visible = true;
notifyIcon.ShowBalloonTip(2000);
}
To display a ballon on mouse hover you want to use the same code as above possibly in the mousemove for the icon.
Note: ShowBalloonTip is overloaded if you want to change the message at different points. The message the balloon displays will respect newlines eg Environment.NewLine can be added to it.

to minimize
this.WindowState = FormWindowState.Minimized;

What's the proper way to minimize to tray a C# WinForms app?

The popup balloon will display whatever is shown in the form's title bar (which is the form's .Text property). I don't know of any way to make it multi-lined (if there is a way, it's sure to be complicated and probably not worth the trouble).
This earlier question gives some answers to the basic question. Your toolbox contains a control called NotifyIcon - use this to place an icon in the system tray.

Universal app does not allow to remove or disable the close button it seems. We can hide it by going full screen. But when moving cursor over it, brings title bar back. Is there any way to remove the close button?
Reason : I am working on screen time. After allowed time gets over, I want to block the screen. I should remove close button so that user cant get over my app.
Edit : Removing close button wont help completely. It is a part of work. I am just asking how to remove it.
In Windows 10 version 1703 (build 10.0.15063) and beyond, you can prevent the app from closing, using the SystemNavigationManagerPreview class.
Add this to your app manifest:
<Capabilities>
<rescap:Capability Name="confirmAppClose" />
</Capabilities
You need to have the rescap namespace at the Package element:
xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
In the constructor of your main form, add:
var sysNavMgr = SystemNavigationManagerPreview.GetForCurrentView();
sysNavMgr.CloseRequested += OnCloseRequested;
OnCloseRequested can be implemented as follows:
private void OnCloseRequested(object sender, SystemNavigationCloseRequestedPreviewEventArgs e)
{
var deferral = e.GetDeferral();
e.Handled = true;
deferral.Complete();
}
With current released API, we are able to customize the color of these three buttons in title bar. But there is no property or method could be used to disable or remove these buttons.
In UWP, we can use ApplicationView.TitleBar | titleBar property to get the title bar like following:
ApplicationViewTitleBar titleBar = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().TitleBar;
This property's type is ApplicationViewTitleBar. It only has several properties that can customize the button's color like:
titleBar.ButtonBackgroundColor = Windows.UI.Colors.White;
titleBar.ButtonForegroundColor = Windows.UI.Colors.White;
titleBar.ButtonHoverBackgroundColor = Windows.UI.Colors.White;
titleBar.ButtonHoverForegroundColor = Windows.UI.Colors.White;
titleBar.ButtonInactiveBackgroundColor = Windows.UI.Colors.White;
titleBar.ButtonInactiveForegroundColor = Windows.UI.Colors.White;
titleBar.ButtonPressedBackgroundColor = Windows.UI.Colors.White;
titleBar.ButtonPressedForegroundColor = Windows.UI.Colors.White;
Using these properties may make the close button invisible like:
However this won't actually hide these buttons. Users can still minimize or maximize the app and when the pointer is over the top right corner, they will still see the close button.
From Windows 8.1, if we want users to use only an application and do nothing else including closing the application, we can use Kiosk Mode. For more info, please see Enable Kiosk Mode in Windows 8.1 and Set up a kiosk on Windows 10 Pro, Enterprise, or Education. However this won't meet your requirement as you want to block the screen after allowed time gets over.
So UWP may not be the best choice for your requirement. You may try to implement it with classic desktop apps.
in App.Xaml.cs add this code :
// Collapse Title bar
CoreApplication.GetCurrentView().TitleBar.ExtendViewIntoTitleBar = true;
Window.Current.SetTitleBar(null);
ApplicationView view = ApplicationView.GetForCurrentView();
view.TryEnterFullScreenMode();
C++ Version
// COLLAPSE THE TITLE BAR
Windows::ApplicationModel::Core::CoreApplication::GetCurrentView()->TitleBar->ExtendViewIntoTitleBar = true;
Window::Current->SetTitleBar(nullptr);
Windows::UI::ViewManagement::ApplicationView^ view = Windows::UI::ViewManagement::ApplicationView::GetForCurrentView();
view->TryEnterFullScreenMode();
I'm trying to find a way to hide the main form of my app from Alt-Tab list after minimizing it. So far I found that setting form style to SizableToolWindow does the trick, but this seems like an improper solution.
I have two winform apps. One of them is supposed to only have tray icon visible, but it still has the main form. Alt-Tab visibility problem is resolved there by doing this.Hide() in Form_Shown method. The other app does not have Form_Shown, but it has Form1_SizeChanged method with code:
this.Hide();
this.ShowInTaskbar = false;
…and for some reason it does not result in the same as the first app. I could only hide it from Alt-Tab list by also setting the main form's style to SizableToolWindow. While it's working, I'd like to know why the supposedly proper approach does not.
Putting this.ShowInTaskbar = false before this.Hide() should hide the form from Alt-Tab list. Apparently, you have to set the visibility option before hiding the form, or it will not hide the window from Alt-Tab. With this there is no need to set the form style to ToolWindow. As for the "why", I have no idea.
i am using this code under my form1_load
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(5000, "Welcome", "Hello " + User, ToolTipIcon.Info);
I even checked my registery and the value was 1. Why is the baloon not showing?
I do have a icon form my notify icon. and it is showing up. The Baloon is not though!
Looks like you forgot to set the Icon for it like this
notifyIcon1.Icon = SystemIcons.Exclamation;
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(5000, "Welcome", "Hello " + User, ToolTipIcon.Info);
Also please read for more inormation on issues with NI http://www.csharp411.com/notifyiconshowballoontip-issues/
You may need to post the rest of the code that's in your form's load event, but here's a couple of suggestions:
Make sure the form's Load event is actually hooked up.
Make sure you've assigned an icon for the notify icon.
Also, note that the balloon tip isn't guaranteed to show. See the Remarks section on msdn's NotifyIcon.ShowBalloonTip Method article:
Remarks Minimum and maximum timeout values are enforced by the operating system and are typically 10 and 30 seconds,
respectively, however this can vary depending on the operating system.
Timeout values that are too large or too small are adjusted to the
appropriate minimum or maximum value. In addition, if the user does
not appear to be using the computer (no keyboard or mouse events are
occurring) then the system does not count this time towards the
timeout.
Only one balloon tip can display on the taskbar at a time. Attempting
to display a balloon tip when one is currently displayed on the
taskbar causes the timeout value to be ignored. The behavior is
slightly different depending on the operating system and whether the
balloon tip is from another, or the same, application. When the second
balloon tip is from another application, the first balloon tip will
display for the minimum timeout value before the second appears,
regardless of the value of timeout. In most cases, if the balloon tips
are from the same application, the first balloon tip immediately
closes when another call to the ShowBalloonTip method is made. In some
cases the second balloon will open on top of the first balloon.
The title text will display in a bold font near the top of the
balloon.
Here is some sample code for what #MetroSmurf has already mentioned. Note that this.InitializeComponent(); must be called before the NotifyIcon is shown (usually in the form constructor).
public Form1()
{
this.InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
notifyIcon1.Icon = new Icon(#"C:\SomePath\MyIcon.ico");
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(5000, "Welcome", "Hello " + User, ToolTipIcon.Info);
}
Also ensure that windows is configured to allow notifications. In Windows 7 right-click taskbar, click Properties, Customize... in the notification area, tick the Always show all icons and notifications on the taskbar option, click OK.
I have a NotifyIcon which shows Baloon Tips with some information. Is there a way to send some command to close this BaloonTip depending on my choice from within code (and not by using mouse)?
a) Click BaloonTip (normally by clicking anywhere within the TrayTip)
b) Close BaloonTip (normally by pressing X in TrayTip window).
Answering my own question:
To show BaloonTip:
NotifyIcon.ShowBalloonTip(4, "Something", "Somnething2", ToolTipIcon.Info);
To make BaloonTip dissapear right away one have to use
NotifyIcon.Visible = false;
NotifyIcon.Visible = true;
I needed to update the system tray icon's text value, of my application, whenever a user hovers over it. I noticed that no such event exists for system tray icons. Is it possible to create a hover event for a system tray icon and if so how can I go about accomplishing it?
How about hooking into NotifyIcon.MouseMove?
As a basic example, this seems to work (with a NotifyIcon on a Form):
public Form1() {
InitializeComponent();
notifyIcon1.MouseMove += delegate
{
notifyIcon1.Text = DateTime.Now.TimeOfDay.ToString();
};
notifyIcon1.Icon = SystemIcons.Hand;
notifyIcon1.Visible = true;
}
In WPF, UI Elements have a ToolTipOpening/ToolTipClosing event. You should update the tooltip text in the opening. I don't know if system tray icons have such behavior, but i guess there is something similar.
