tid: TNotifyIconData;
WndClass: array[0..50] of char; {现在进入程序的主要部分,首先是定义了一批过程,为了能让读者更好地理解,我们先 把这些过程跳过 去,先说主程序。主程序位于程序的最后,这样做的好处是可以直接使用程序中定义的过程。主程序十分 简单:}
begin
WinMain;
end.
{看来所有的工作都由 WinMain 完成了。这个 WinMain 使用标准的 WinAPI 函数进行编 程,主要步骤 是:先声明一个窗口类,然后创建一个主窗口,最后进入消息循环,直到程序结束。}
procedure WinMain; var
Wnd: hWnd; {声明窗口句柄(Handle)变量}
Msg: TMsg; {声明消息变量}
cls: TWndClass; {窗口类变量}
begin { Previous instance running ? If so, exit } { 检查是否程序已经运行,如果已经运行则调用Panic过程退出 } if FindWindow (AppName, Nil) <> 0 then Panic (AppName + ' is already running.'); { Register the window class } { 这里的注册窗口类程序是例行公事,照抄即可} FillChar (cls, sizeof (cls), 0); {用这一句将窗口类变量cls清零)
cls.lpfnWndProc := @DummyWindowProc; {取回调函数DummyWindowProc的地址}
cls.hInstance := hInstance; {实例句柄}
cls.lpszClassName := AppName; {窗口类名}
RegisterClass (cls); {注册窗口类cls} { 现在可以创建程序的主窗口了-在本程序中是个虚拟窗口} { Now create the dummy window }
Wnd := CreateWindow (AppName, AppName, ws_OverlappedWindow, cw_UseDefault, cw_UseDefault, cw_UseDefault, cw_UseDefault, 0, 0, hInstance, Nil);
x:= 0; {变量X其实是个开关变量,记录现在是否已经隐藏了桌面}
{ 如果窗口创建成功,则显示窗口,并进入消息循环 } if Wnd <> 0 then
begin
ShowWindow (Wnd, sw_Hide);{本例中窗口是隐藏的} { 下面进入消息循环,该循环将不断运行直到 GetMessage返回0 } while GetMessage (Msg, 0, 0, 0) do
begin
TranslateMessage (Msg);
DispatchMessage (Msg);
end;
end;
end;
{现在看来,程序的主框架很明了,但是它还不能完成任何任务。过程 Panic将显示一个对话框后退出程序,它在 Winmain 过程的开始部分被调用,其实 Panic的功能很简单,之所以要写成一 个函数的原因恐 怕一方面是结构化编程的需要,另一方面借此避开了 String和 PChar 的转换。} procedure Panic (szMessage: PChar);
begin
if szMessage <> Nil then MessageBox (0, szMessage, AppName, mb_ok);
Halt (0);
end; {下面是回调(Callback)函数 DummyWindowProc,如果说 Winmain 过程是本程序-或者说是本应用或实 例的生命,那么这个回调函数可以说是主窗口的灵魂。每一个标准的或者说是规范的 Windows窗口都有一 个回调函数,以处理发给该窗口的消息。所谓“回调”的意思是这个函数不是由程序直接 调用的,而是由 Windows 系统调用(还记得我们在窗口类中给lpfnWndProc赋过值吗), 这就是事件驱动编程。} function DummyWindowProc (Wnd: hWnd; Msg, wParam: Word; lParam: LongInt) : LongInt; stdcall; {注意这里有一个 stdcall;定义了回调函数}

end; 至此我们已经完成了这个只有38K的能将Win95桌面隐藏起来的程序,只要将本文中所有的函数和过程的顺序倒置,并将主程序放到最后,即可编译通过。 作者:不详 来源:不详
如果要追究,就去问MicroSoft吧。
Why not use KOL ????
Delphi2, Delphi3, Delphi4, Delphi5 and Delphi6 are supported. KOL allows to create very compact GUI applications (starting from ~13,5K without compression - if suggested system units replacement used). The most of code is converted to assembler.
还有...
program Project1;{$APPTYPE CONSOLE}
VAR ZXB:STRING;begin
{ TODO -oUser -cConsole Main : Insert code here }
** WRITE('WHO ARE YOU ?');
readln(zxb);
writeln('hello!',zxb,',welcome');
readln;
**
end.
**中间是自己添加的代码,并将USE语句删除。
编译看看吧!
但是,要记得,你发布程序,必须带你需要的运行时间包文件,*.bpl.至于需要哪些bpl就要看你用了哪些vcl控件了!
