Poss. to find out Child controls from the Parent?

[LucieLastic]

hi

I have a form created at runtime. Combos are added (at runtime) to the form depending of whats required.

The form is then 'assigned' to a TabSheet by setting it's Parent := tabsheet.

In my interface, there's a copy button and all I know is the Parent tabsheet. I want to be able to get all the child controls on the tabsheet and copy their information to a new form containing a new tabsheet. Also, the owner of all the controls is a datamodule.

Components and ComponentCount don't work as Tabsheet comes up as having 0 components, I think because all the controls I want are overlayed on a form.

Is it possible?

One more question, is is possible to sendMessage to a Datamodule as a datamodule doesn't have a handle?

Could you loop through the components on the form, and then check to see who the parent is?

For i := 0 to Form1.ComponentCount - 1 do
begin
if Form1.Components.Parent = Tabsheet then
begin
CopyToOtherForm(NewForm,Form1.Components);
end;
end;

Or could you use the tag property and synchronize the tag of the child properties with a tag you assign to a tabsheet?

hi Brian

Thanks for the reply. I now have it working. I had to set the Owner of the overlay form to be the tabsheet - I was under the impression that setting the Parent to be the tabsheet would have been sufficient.

thanks again
