);
Retrieves an index value for an item based on its order in the header control. You can use this macro or send the HDM_ORDERTOINDEX message explicitly.
Returns an INT that specifies the index of the item. If iOrder is invalid (negative or too large), the return equals iOrder.

hwndHD
Handle to a header control.
iOrder
Order that the item appears within the header control, from left to right. The index value of the item in the far left column would be 0, the next item to the right would be 1, and so on.
