Title: Storing icons in your application for use at runtime
Question: How can I store icons in my application and use them at runtime?
Answer:
Create a resource file containing the icons you wish to use, then
use the Windows API function LoadIcon(),
Example:
{$R MYRES.RES}
procedure TForm1.Button1Click(Sender: TObject);
var
h : hIcon;
begin
h := LoadIcon(hInstance, 'ICON_1');
Application.Icon.Handle := h;
InvalidateRect(Application.Handle, nil, true);
end;
