Как таскать форму не за рамку в Delphi?
Данная проблемма часто возникает, когда нужно таскать форму без рамки (WinAMP), но решить её очень просто!
К примеру нужно таскать форму за Label1 находящийся на Form1.

procedure TForm1.Label1MouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
const
SC_DragMove = $F012; { a magic number }
begin
ReleaseCapture;
Form1.perform(WM_SysCommand, SC_DragMove, 0);
end;

Так же и с другими объектами на Form1. Просто обрабатываем событие MousDown.

procedure RegisterFileType( ft, key, desc, icon, prg : string );
var
myreg : TRegIniFile;
ct : Integer;
begin
ct := pos('.',ft);
while ct > 0 do begin
System.Delete(ft,ct,1);
ct := pos('.',ft);
end;
if (ft = '') or (prg = '') then exit;
ft := '.'+ft;
myreg := TRegIniFile.Create('');
try
myreg.rootkey := hkey_classes_root;
if key = '' then key := copy(ft,2,maxint)+'_auto_file';
myreg.writestring(ft,'',key);
myreg.writestring(key,'',desc);
if icon <> '' then
myreg.writestring(key+'\DefaultIcon','',icon);
myreg.writestring(key+'\shell\open\command','',prg+' "%1"');
finally
myreg.Free;
end;
end;

Не знаю какой параметр за что отвечает. :-(

Юмор
Однажды молодой сисадмин, открыв свой почтовый ящик, нашел там повестку в райвоенкомат.
- Опять этот чертов спам, - прорычал он, нервно разрывая повестку в клочья.

Звонок на радио:
- Поставьте, пожалуйста, песню Пугачевой про то, как у нее завис Windows!
Ди-джей (после паузы):
- Я не могу вспомнить у Пугачевой такой песни! Можете напеть?
- Ну, там еще в припеве: "Кликну, а в ответ тишина, снова я осталась одна. Сильная
женщина плачет у Окна"
