22 /* TO TEST:
23  *   - send click messages to the up-down control, check the current position
24  *   - up-down control automatically positions itself next to its buddy window
25  *   - up-down control sets the caption of the buddy window
26  *   - test CreateUpDownControl API
27  *   - check UDS_AUTOBUDDY style, up-down control selects previous window in z-order
28  *   - check UDM_SETBUDDY message
29  *   - check UDM_GETBUDDY message
30  *   - up-down control and buddy control must have the same parent
31  *   - up-down control notifies its parent window when its position changes with UDN_DELTAPOS + WM_VSCROLL or WM_HSCROLL
32  *   - check UDS_ALIGN[LEFT,RIGHT]...check that width of buddy window is decreased
33  *   - check that UDS_SETBUDDYINT sets the caption of the buddy window when it is changed
34  *   - check that the thousands operator is set for large numbers
35  *   - check that the thousands operator is not set with UDS_NOTHOUSANDS
36  *   - check UDS_ARROWKEYS, control subclasses the buddy window so that it processes the keys when it has focus
37  *   - check UDS_HORZ
38  *   - check changing past min/max values
39  *   - check UDS_WRAP wraps values past min/max, incrementing past upper value wraps position to lower value
40  *   - can change control's position, min/max pos, radix
41  *   - check UDM_GETPOS, for up-down control with a buddy window, position is the caption of the buddy window, so change the
42  *     caption of the buddy window then call UDM_GETPOS
43  *   - check UDM_SETRANGE, max can be less than min, so clicking the up arrow decreases the current position
44  *   - more stuff to test
