Did you try looking at the help on TPanel? It says specifically that you need to specify an owner. That's either another component or a window. Where is this panel suppose to be created? What is it part of? Is it just a panel on the desktop? If so then you at a minimum need to tell it to create it on the desktop if that would even work.
i know, i have to create it on the form...thats why i said it has something to do with Parent Form1 and what not
you didnt help me, i have looked in every help file i have, and all it says is
Panel1 = new TPanel();
thats it....its not just panel or anything...its any object
Image1 = new TImage();
Button1 = new TButton();
anything....if you use borland you would know what im trying to say...

IIRC, when i used Delphi (it uses almost same VCL) , i had to create it passing parent, and maybe also make it visible.. something like show(). But i don't sure, i have never used VCL really much.
Hi GT70sgt,
Something like this should help you out, its been a while but I used to use BCB myself :)
Dont forget to delete the panels you create - if you need any more help just let me know
Chris.
