Practical Learning: Configuring a Tree Control

1. To create the items for the tree control, access the OnInitDialog() event of the
   CCarInventory2Dlg class and type the following:

BOOL CCarInventory2Dlg::OnInitDialog()

{

CDialog::OnInitDialog();

// Set the icon for this dialog. The framework does this automatically

// when the application's main window is not a dialog
