请问各位高手，如何存储一个含子控件的控件到文件里，然后再读出来，不是分别存、读？(100分)

请问各位高手，如何存储一个含子控件的控件到文件里，然后再读出来，不是分别存、读？

function ComponentToString(Component: TComponent): string;

var
BinStream:TMemoryStream;
StrStream: TStringStream;
s: string;
begin
BinStream := TMemoryStream.Create;
try
StrStream := TStringStream.Create(s);
try
BinStream.WriteComponent(Component);
BinStream.Seek(0, soFromBeginning);
ObjectBinaryToText(BinStream, StrStream);
StrStream.Seek(0, soFromBeginning);
Result:= StrStream.DataString;
finally
StrStream.Free;

end;
finally
BinStream.Free
end;
end;

function StringToComponent(Value: string): TComponent;
var
StrStream:TStringStream;
BinStream: TMemoryStream;
begin
StrStream := TStringStream.Create(Value);
try
BinStream := TMemoryStream.Create;
try
ObjectTextToBinary(StrStream, BinStream);
BinStream.Seek(0, soFromBeginning);
Result := BinStream.ReadComponent(nil);

finally
BinStream.Free;
end;
finally
StrStream.Free;
end;
end;

to yyanghhong:
读出控件时提示：class T.... not fount.即第二个控件的类找不到。其中第二个控件
为 非 Twincontrol 类。

because the child component is referenced by parent component,
not a part of parent component, parent component only contain a pointer
of his child component.
so you have to convert the child to a string first,
then convert the parent. then save two string to a file.
when you like to load them from file, load the child first, then load the parent

接受答案了.
