listview排序

int WINAPI CustomSortProc(LPARAM Item1,LPARAM Item2,LPARAM ParamSort) 
{ 
    static bool b=true;
    if(b)
    {
        b=false;
        return   -CompareText(((TListItem*)Item1)-> Caption,   
                 ((TListItem*)Item2)-> Caption);
    }
    else 
    {     
        b=true;
        return  CompareText(((TListItem*)Item1)-> Caption,   
                ((TListItem*)Item2)-> Caption);
    }    
}

下面要触发排序，一般写在OnColumnClick事件中：

ListView1-> CustomSort(CustomSortProc,0);
