Using CBuilder3, suppose I have a form with a ScrollBox  and TreeView component. I want to place an Image component or a Button component dynamically within the scrollBox for every image in the selected directory of the treeview component much like Imaging programs do. Can a CBuilder3 expert help.

 TButton *Button = new TButton(ScrollBox1);
  Button->Left = 10;
  Button->Top = 20;
  Button->Caption = "Click me";
  ScrollBox1->InsertControl(Button);

Most common mistake made (i think) is that the new component is not given a parent. You can see in the answer you already got from D here that the parent can be set in the instance. Also possible in stead of
new TButton(ScrollBox1) ;
 

Button->Parent = ScrollBox1;
If you don't give the control / component a name it'll be "floating" (of nulled) and you'll get the weirdest errors!

Good luck !
