I would like to be able to delete an item listed in a dialog listbox by using the del key.  How do I go about it because in a dialog, keyboard input is only possible to an edit control.

You should do the following:
1. Add the LBS_WANTKEYBOARDINPUT style to your listbox in the resource file where the dialog box is defined.
2. Add the following code in your dialog box function:
  // Assuming that the listbox is has Id of IDC_LISTBOX1.
  case WM_VKEYTOITEM:
    if (LOWORD(wParam) == VK_DELETE) {
       int iIndex = SendDlgItemMessage(hDlg, IDC_LISTBOX1, LB_GETCURSEL, 0, 0);
       if (iIndex >= 0)
          SendDlgItemMessage(hDlg, IDC_LISTBOX1, LB_DELETESTRING, iIndex, 0);
      }
      return (-1);

3. In case you're using win16 (and not win32) then replace the LOWORD(wParam) with wParam.

4. The delete key will be detected when the listbox has the keyboard focus.
