HDM_SETORDERARRAY
    wParam = (WPARAM) (int) iSize;
    lParam = (LPARAM) lpiArray;

Sets the left-to-right order of header items. You can send this message explicitly or use the Header_SetOrderArray macro.

iSize
Size of the buffer at lpiArray, in elements. This value must equal the value returned by HDM_GETITEMCOUNT.
lpiArray
Address of an array that specifies the order in which items should be displayed, from left to right. For example, if the contents of the array are {2,0,1}, the control displays item 2, item 0, and item 1, from left to right.
