There is nothing wrong with the code.
It appears to be your OS level settings of <code>Notification Area Icons</code> that is wrong (= <code>Hide icon and notifications</code>).
Open <code>Control Panel\All Control Panel Items\Notification Area Icons</code> and select either <code>Only show notifications</code> or <code>Show icon and notifications</code> for your application.

For the sake of current and future Internet searchers, i'll say that my problem was with XE5 and Windows 10 (it worked fine in Windows XP). Turned out that I stupidly turned on the priority mode, which hides Notifications .. and also trayicon's balloonhints.

blocks|key|1265498|text|你需要做一些不同的事情。首先，您需要检查表单何时最小化。这可以通过捕获消息WM_SIZE来完成。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1265499|procedure+WMSize(var+Msg:+TMessage);+message+WM_SIZE;|code-block|syntax|javascript|1265500|然后：|1265501|procedure+TForm1.WMSize(var+Msg:+TMessage);

You need to do it a bit differently. First of all you need to check for when the form minimizes. That could be done by catching the message <code>WM_SIZE</code>

<pre><code>procedure WMSize(var Msg: TMessage); message WM_SIZE;
</code></pre>

And then:

<pre><code>procedure TForm1.WMSize(var Msg: TMessage);
begin
 if Msg.WParam = SIZE_MINIMIZED then ....
end;
</code></pre>

Typically you also want the close button to minimize the Application. That could be achived by implementing a CloseQuery event.

I've made you a small example based on your own code.

First the DFM code:

<pre><code>object Form11: TForm11
 Left = 0
 Top = 0
 Caption = 'Form11'
 ClientHeight = 299
 ClientWidth = 635
 Color = clBtnFace
 Font.Charset = DEFAULT_CHARSET
 Font.Color = clWindowText
 Font.Height = -11
 Font.Name = 'Tahoma'
 Font.Style = []
 OldCreateOrder = False
 OnCloseQuery = FormCloseQuery
 OnCreate = FormCreate
 OnHide = FormHide
 PixelsPerInch = 96
 TextHeight = 13
 object TrayIcon1: TTrayIcon
 OnDblClick = TrayIcon1DblClick
 Left = 312
 Top = 152
 end
 object PopupMenu1: TPopupMenu
 Left = 184
 Top = 112
 object Close1: TMenuItem
 Caption = 'Close'
 Default = True
 OnClick = Close1Click
 end
 end
end
</code></pre>

Then the actual sourcecode:

<pre><code>unit Unit11;

interface

uses
 Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
 Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.ExtCtrls, Vcl.Menus;

type
 TForm11 = class(TForm)
 TrayIcon1: TTrayIcon;
 PopupMenu1: TPopupMenu;
 Close1: TMenuItem;
 procedure FormCreate(Sender: TObject);
 procedure FormHide(Sender: TObject);
 procedure FormCloseQuery(Sender: TObject; var CanClose: Boolean);
 procedure Close1Click(Sender: TObject);
 procedure TrayIcon1DblClick(Sender: TObject);
 private
 AllowClose: Boolean;
 public
 procedure WMSize(var Msg: TMessage); message WM_SIZE;
 end;

var
 Form11: TForm11;

implementation

{$R *.dfm}

procedure TForm11.Close1Click(Sender: TObject);
begin
 AllowClose := True;
 Close;
end;

procedure TForm11.FormCloseQuery(Sender: TObject; var CanClose: Boolean);
begin
 CanClose := AllowClose;
 if not AllowClose then
 Hide;
end;

procedure TForm11.FormCreate(Sender: TObject);
begin
 AllowClose := false;
 TrayIcon1.Hint := 'Hint';
 TrayIcon1.AnimateInterval := 200;
 TrayIcon1.BalloonTitle := 'Hint';
 TrayIcon1.BalloonHint := 'Double click to restore Application';
 TrayIcon1.BalloonFlags := bfInfo;
end;

procedure TForm11.FormHide(Sender: TObject);
begin
 TrayIcon1.Visible := True;
 TrayIcon1.Animate := True;
 TrayIcon1.ShowBalloonHint;
end;

procedure TForm11.TrayIcon1DblClick(Sender: TObject);
begin
 TrayIcon1.Visible := false;
 Show();
 WindowState := wsNormal;
 Application.BringToFront();
end;

procedure TForm11.WMSize(var Msg: TMessage);
begin
 if Msg.WParam = SIZE_MINIMIZED then
 Close;
end;

end.
</code></pre>

I use this code to show a <code>TrayIcon</code> it works and the <code>TrayIcon</code> appears in the Systray but it doesn't show the <code>BalloonHint</code>; I tried to change some setting but it still doesn't show the notification

<pre><code>procedure TMainForm.FormCreate(Sender: TObject);
begin
 TrayIcon1.Hint := 'Hint';
 TrayIcon1.AnimateInterval := 200;
 TrayIcon1.BalloonTitle := 'Hint';
 TrayIcon1.BalloonHint := 'Double click to restore Application';
 TrayIcon1.BalloonFlags := bfInfo;
end;

procedure TMainForm.ApplicationEvents1Minimize(Sender: TObject);
begin
 Hide();
 WindowState := wsMinimized;
 TrayIcon1.Visible := True;
 TrayIcon1.Animate := True;
 TrayIcon1.ShowBalloonHint;
end;

procedure TMainForm.TrayIcon1DblClick(Sender: TObject);
begin
 TrayIcon1.Visible := False;
 Show();
 WindowState := wsNormal;
 Application.BringToFront();
end;
</code></pre>

what is wrong with this code?

<hr>

The project is originally written in Delphi7 and now upgraded to DelphiXE8.

TrayIcon doesn't show notification
