关于任务栏崩溃，托盘图标消失的问题
小弟在网上看了个任务栏崩溃，重建托盘图标的代码，里面有个settryico未定义，不知道需要包含什么，哪位大哥告知下。
还是settryico是自己写的？

代码如下：
unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs;

type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
private
procedure WndProc(var msg: Tmessage); override; //任务栏恢复消息(继承)
public
{ Public declarations }
end;

var
Form1: TForm1;
TaskBarMSG: Dword; //任务栏恢复消息

implementation

{$R *.dfm}

{ TForm1 }

procedure TForm1.WndProc(var msg: Tmessage); //任务栏恢复消息
begin
if msg.msg = TaskBarMSG then SetTryico(Handle, Icon.Handle, AppTray); //重设ICON
inherited WndProc(msg);
end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
TaskBarMSG := RegisterWindowMessage('HTaskBarCreated'); //注册任务栏恢复消息
end;

end.
