Delphi: what are the 8 mystery components on my form?

Question

When I iterate of the controls on my form, I see those which I placed there at design time or run time. They are all of type TEdit, Tmemo, TComboBox, etc ...

However, there are always exactly eight which I do not recognize. I can skip over them, since they are not of a type which interests me, but I am curios.

I am guessing system controls like min/max/close. Their Name property is empty. Is there any way I can determine what type they are (without explicitly testing for every standard component derived from TWinControl) ?

I am curious - but not yellow ;-)

for i := 0 to Form1.ControlCount -1 do ...

Answer: use ClassName to find out. And i got TGrabHandle for all of them.

Thanks for all the help. +! all round

Answer 1

TObject has the property ClassName; Try to access and interrogate this property for this components.
Paste the code block (for/while) that you are using for interrogate the form, for search components.

Answer 2

Use their ClassName to get an idea of wht they are when the Name property is empty.
