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