你用一个 系统托盘控件.TrayIcon1
在lmd控件包里有。 www.51delphi.com里有下载.Application.Minimize; //最小化Application.Restore; //恢复
将trayicon1.enabled:=True; 就会自动缩小到状态栏

个小图标,当鼠标移到这个小图标上时会出现一些提示信息、单击该小图标会
执行一些特定的操作。便如任务条右下角的小喇叭图标,单击它会弹出一个简
单的音量控制条,双击会启动另一个更大的音量控制程序。
在Shell32.DLL动态链接库中包括一个函数Shell_NotifyIconA()可通知
Windows在任务条右下角加入一个小图标,可惜该函数的详细说明未收入Delphi
的帮助文档中,下面以一个简单的实例来说明如果使用该函数。 unit Unit1; interface { 记住在uses部分中包括 ShellAPI}
uses
Windows, Messages, SysUtils, Classes,
Graphics, Controls, Forms, Dialogs,
ShellAPI, StdCtrls; {自定义消息,当小图标捕捉到鼠标事件时Windows向回调函数发送此消息}

end;
end; {当主Form建立时通知Windows加入小图标}
procedure TForm1.FormCreate(Sender: TObject);
var
nid: TNotifyIconData;
begin
nid.cbSize := sizeof(nid); // nid变量的字节数
nid.Wnd := Handle; // 主窗口句柄
nid.uID := -1; // 内部标识,可设为任意数
nid.hIcon := Application.Icon.Handle; // 要加入的图标句柄,可任意指?
nid.hIcon := Application.Icon.Handle; // 要加入的图标句柄,可任意指?nid.szTip := 'This is a test application'; // 提示字符串
nid.uCallbackMessage := MY_MESSAGE; // 回调函数消息
nid.uFlags := NIF_ICON or NIF_TIP or NIF_MESSAGE; // 指明哪些字段有?if not Shell_NotifyIcon(NIM_ADD, @nid) then begin
ShowMessage('Failed!');
Application.Terminate;
end;
{将程序的窗口样式设为TOOL窗口,可避免在任务条上出现}
SetWindowLong(Application.Handle, GWL_EXSTYLE, WS_EX_TOOLWINDOW);
end; {程序被关闭时通知Windows去掉小图标}
procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
var
nid: TNotifyIconData;
begin
nid.cbSize := sizeof(nid); // nid变量的字节数
nid.cbSize := sizeof(nid); // nid变量的字节数
nid.uID := -1; //内部标识,与加入小图标时的数一致
nid.Wnd := Handle; //主窗口句柄
Shell_NotifyIcon(NIM_DELETE, @nid); //去掉小图标
Shell_NotifyIcon(NIM_DELETE, @nid); //去掉小图标
end; {主窗口初始化完毕并显示时将激活Paint重画事件,此时将主窗口隐藏}
procedure TForm1.FormPaint(Sender: TObject);
begin
Hide;
end; end. 上例中将程序的图标放在任务条右下角,然后隐藏自身,当用户移动鼠标
至该图标上时会看到提示字符串,如果单击该图标会出现一个对话框,选择Yes退出程序并清除小图标。
”偶初学,搞不懂,能不能把该代码做的示例发到[email protected],第一个发的给80分,请帮忙,十分感谢!(请注明您在此的用户名,并且在此发一帖,以便加分)

就是nid.uID :=-1;改成
nid.uID :=0;就可以通过了!
