who can create a form as another form's child.Using borland c++ ,this
task is very easy,but using delphi or vb I'm confused.

There are two ways I know to do this.

1. If you intend your form to be a control and register it, you need
to override Create to ensure the form has a parent before its Create
is called (this requires you to assume that AOwner supplied to Create
is a TWinControl, but I've yet to see this assumption fail) and
CreateParams to strip some flags which would make your form look like
a resizable window.
(In Delphi 2 it's not necessary to override Create - it seems to work
even without a parent).

2. If you just want to embed a form at run-time, you can use code such
as this:
  newform := TYourFormClass(TYourFormClass.NewInstance);
  with newform do begin
    Parent := Self;
    Create(Self);
  end;
This is similar to what goes on in Application.CreateForm, and as far
as I know it's harmless and produces the expected result. Again, you
may want to set newform's style to bsNone, otherwise it'll have a
window border.

I use panels in different windows and set their Parent properties to
another form or to individual pages in a TNotebook in another form. I do
this to split the source into several files.

If you want the secondary form to be modal, just set its position on create.
This approach allows you to serarate the code into another file and makes the
code generally more reusable.

A third approach- messier but sometimes useful - is to have a lot of invisible
controls and to move them into position (e.g. on a panel) just before making
them visible. Make the main form large for editing and set it to the runtime
size in the OnCreate method.
