托盘运行失败
各位大虾。小弟做托盘程序时运行失败。下面的是从网上找的源码。基本上都是你抄来。我抄去的。Delphi7调试不成功。 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}
{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}
const MY_MESSAGE = WM_USER + 100;
type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
procedure FormClose(Sender: TObject; var Action: TCloseAction);
procedure FormPaint(Sender: TObject);
private
procedure OnIconNotify(var Message: TMessage);
message MY_MESSAGE;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
{当小图标捕捉到鼠标事件时进入此过程}
{当小图标捕捉到鼠标事件时进入此过程}
procedure TForm1.OnIconNotify(var Message: TMessage);
const
Busy: Boolean = false;
begin
if not Busy then begin
Busy := true;
if Message.LParam=WM_LBUTTONDOWN then
if Application.MessageBox('Are you sure',
'Exit', MB_YESNO)=IDYES then Close;
Busy := false;
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.
