win32 listcontrol 排序

win32 liscontrol 排序问题 不能用MFC

Answer 1

给你一个完整的程序代码：
//用列表控件显示磁盘文件列表
//点击文件时，显示文件开头的部分，暂未兼容ANSI、UNICODE，可自行修改
//LB_DIR LB_SORT
#include <windows.h>
#include <tchar.h>
#include <stdio.h>

#define ID_LISTBOX 1
#define ID_EDIT 2

#define MAXREAD 2048
#define DTFLAGS (DT_WORDBREAK|DT_EXPANDTABS|DT_NOCLIP|DT_NOPREFIX)

//全局变量
HINSTANCE hInst;
WNDPROC oldlistboxproc;//旧的列表控件消息处理函数指针

//函数声明
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);//回调函数
LRESULT CALLBACK ListProc (HWND, UINT, WPARAM, LPARAM);//新的列表控件消息处理函数

//程序入口函数
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
MSG msg;//消息结构体

//注册窗口类

RegisterClassEx(&wcex);

//创建和显示窗口
HWND hwnd;
