Type-Safe Access to Controls Without Code Wizards

The first approach to creating type-safe access to controls uses an inline member function to cast the return type of class CWnd's GetDlgItem member function to the appropriate C++ control type, as in this example:

CButton* CMyDialog::GetMyCheckbox()
{
   return (CButton*)GetDlgItem(IDC_CHECKBOX);
}

You can then use this member function to access the control in a type-safe manner with code similar to the following:

GetMyCheckbox()->SetCheck(BST_CHECKED);
