Sort the clistcontrol list header in VC ++

Before declaring the class in the header file XXX. H, define the following content:

Struct mydata
{
Clistctrl * listctrl; // declare the object
Int isub;
Int seq; // determines whether the sequence is ascending or descending.
};

// Callback function

Inline int callback comparefuncs (lparam lparam1, lparam lparam2, lparam lparamsort)
{
Mydata * P = (mydata *) lparamsort;
Clistctrl * List = p-> listctrl;
Int isub = p-> isub;
Lvfindinfo findinfo;
Findinfo. Flags = lvfi_param;
Findinfo. lparam = lparam1;
Int iitem1 = List-> finditem (& findinfo,-1 );
Findinfo. lparam = lparam2;
Int iitem2 = List-> finditem (& findinfo,-1 );
Cstring stritem1 = List-> getitemtext (iitem1, isub );
Cstring stritem2 = List-> getitemtext (iitem2, isub );
// Char * Item1 = (char *) (lpctstr) stritem1;
// Char * item2 = (char *) (lpctstr) stritem2;
If (p-> SEQ)
// Return strcmp (Item1, item2); // The strcmp method is used on the Internet. It is a char-type comparison, so cstring uses the compare method.
Return stritem1.compare (stritem2 );
Else
// Return strcmp (item2, Item1 );
Return stritem2.compare (stritem1 );
};

///// // The callback function does not need to be written by yourself, just copy it directly ////////////////////////////////

Next, we need to instantiate the control.

I applied directly in XXX. h.

Public:
Clistctrl m_list_history;

To instantiate a control:

M_list_history.insertcolumn (0, l "task ");
M_list_history.insertcolumn (1, l "title ");
M_list_history.insertcolumn (2, l "status ");
M_list_history.insertcolumn (3, l "time ");
M_list_history.setcolumnwidth (0, 30); // decrease by 20
M_list_history.setcolumnwidth (1, 57 );////
M_list_history.setcolumnwidth (2, 48 );///
M_list_history.setcolumnwidth (3,160 );///

This is the code of my project. You can instantiate your own controls based on your project (the specific method for instantiating objects is that you can find them on the Internet)

When instantiating your control, remember to use this method: m_list_history.setitemdata (Iitem, I); // sort it

Finally, the onlvncolumnclicklisthistory event is found in the control event (this event occurs when you click the control column)

Void chistorypage: onlvncolumnclicklisthistory (nmhdr * pnmhdr, lresult * presult)
{
Lpnmlistview pnmlv = reinterpret_cast <lpnmlistview> (pnmhdr );
// Todo: add the control notification handler code here
// If (pnmlv-> isubitem = m_nsortedcol1)
Mydata * tmpp = new mydata;
// Tmpp-> listctrl = & m_list;
Tmpp-> listctrl = & m_list_history;
Tmpp-> isub = pnmlv-> isubitem;
Int sortnum = (INT) getprop (m_list_history.getsafehwnd (), L "sort_column ");
Int sortasc = (INT) getprop (m_list_history.getsafehwnd (), L "sort_direction ");
If (sortnum = pnmlv-> isubitem ){
Sortasc = (sortasc + 1) % 2;
Setprop (m_list_history.getsafehwnd (), L "sort_direction", (handle) sortasc );
}
Setprop (m_list_history.getsafehwnd (), L "sort_column", (handle) pnmlv-> isubitem );
Tmpp-> seq = sortasc;
M_list_history.sortitems (& comparefuncs, (lparam) tmpp );
* Presult = 0;
}

You can modify the code by referring to your project, so that the click column of the control is sorted.
