The SB_GETPARTS message retrieves a count of the parts in a status window. The message also retrieves the coordinate of the right edge of the specified number of parts.
SB_GETPARTS
wParam = (WPARAM) nParts;
lParam = (LPARAM) (LPINT) aRightCoord;
Parameters
nParts
Number of parts for which to retrieve coordinates. If this parameter is greater than the number of parts in the window, the message retrieves coordinates for existing parts only.
aRightCoord
Pointer to an integer array that has the same number of elements as parts specified by nParts. Each element in the array receives the client coordinate of the right edge of the corresponding part. If an element is set to - 1, the position of the right edge for that part extends to the right edge of the window. To retrieve the current number of parts, set this parameter to zero.
Return Values
Returns the number of parts in the window if successful, or zero otherwise.
