This message sorts list-view items using an application-defined comparison function. The index of each item changes to reflect the new sequence. You can send this message explicitly or by using the ListView_SortItemsmacro.

Syntax 

LVM_SORTITEMS 
wParam = (WPARAM)(LPARAM) 
lParamSort; 

lParam = (LPARAM)(PFNLVCOMPARE) 
pfnCompare;

Parameters

lParamSort

Application-defined value passed to the comparison function.

pfnCompare

Pointer to the application-defined comparison function. The comparison function is called during the sort operation each time the relative order of two list items needs to be compared.

Return Value

TRUE indicates success. FALSE indicates failure.

Remarks

The comparison function has the following form.

Copy Code 
int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, 
LPARAM lParamSort);

The lParam1parameter is the 32-bit value associated with the first item being compared, and the lParam2parameter is the value associated with the second item. These are the values specified in the lParammember of the items' LVITEMstructure when they were inserted into the list. The lParamSortparameter is the same value passed to the LVM_SORTITEMS message.
