消息
1. 添加条目
1) 添加纯字符串的条目添加字符串到列表框最后一项：SendMessage (hwndList, LB_ADDSTRING, 0, (LPARAM)string);创建列表框时指定LBS_SORT选项则自动排序添加字符串到列表框指定位置：SendMessage (hwndList, LB_INSERTSTRING, index, (LPARAM)string);index=-1时，添加到最后一项创建列表框时指定LBS_SORT选项则自动排序，忽略index
2) 添加含图标的条目LISTBOXITEMINFO lbii;lbii.hIcon = LoadIconFromFile (HDC_SCREEN, "res.ico", 1);lbii.cmFlag = CMFLAG_CHECKED;lbii.string = "abcdefg";SendMessage (hwndList , LB_ADDSTRING, 0, (LPARAM)&lbii);
3) 添加含位图的条目LISTBOXITEMINFO lbii;lbii.hIcon = (DWORD) GetSystemBitmap (SYSBMP_MAXIMIZE);lbii.cmFlag = CMFLAG_CHECKED | IMGFLAG_BITMAP;lbii.string = "abcdefg";SendMessage (hwndList , LB_ADDSTRING, 0, (LPARAM)&lbii);
4) 添加多个纯字符串条目int num = 2;const char text[num][] = {“item1”, “item2”};SendMessage (hwndList, LB_MULTIADDITEM, num, (LPARAM)text);
5) 添加多个含图标、位图或复选框的条目int num = 2;LISTBOXITEMINFO lbii[num];lbii[0].hIcon = LoadIconFromFile (HDC_SCREEN, "res1.ico", 1);lbii[0].cmFlag = CMFLAG_CHECKED;lbii[0].string = "item1";lbii[1].hIcon =LoadIconFromFile (HDC_SCREEN, "res2.ico", 1);lbii[1].cmFlag = CMFLAG_CHECKED;lbii[1].string = "item2";SendMessage (hwndList, LB_MULTIADDITEM, num, (LPARAM)lbii);返回值：LB_ERRSPACE 内存不足LB_ERR 其他原因错误LB_OKAY 成功
2. 删除条目
删除指定条目：SendMessage (hwndList, LB_DELETESTRING, index, 0);清空列表框内容：SendMessage (hwndList, LB_RESETCONTENT, 0, 0);
3. 选择和取得条目
获取条目个数：int count = SendMessage (hwndList, LB_GETCOUNT, 0, 0);获取指定条目字符串长度：int length = SendMessage (hwndList, LB_GETTEXTLEN, index, 0);获取指定条目字符串： int length = SendMessage (hwndList, LB_GETTEXT, index, (LPARAM)buffer);设置指定条目字符串：SendMessage (hwndList, LB_SETTEXT, index, buffer);
设置高级列表框指定条目：LISTBOXITEMINFO lbii;lbii.hIcon = LoadIconFromFile (HDC_SCREEN, "res.ico", 1);lbii.cmFlag = CMFLAG_CHECKED;lbii.string = "set item";SendMessage (hwndList , LB_SETITEMDATA, index, (LPARAM)&lbii);获取高级列表框指定条目：LISTBOXITEMINFO lbii;SendMessage (hwndList , LB_GETITEMDATA, index, (LPARAM)&lbii);
单选列表框设置选中条目：SendMessage (hwndList, LB_SETCURSEL, index, 0);单选列表框获取选中条目的索引项：int index = SendMessage (hwndList, LB_GETCURSEL, 0, 0);如果没有条目被选中，返回LB_ERR
多选列表框设置指定条目的选中状态：SendMessage (hwndList, LB_SETSEL, wParam, (LPARAM)index);wParam非0则选择并加亮某一条目，0则取消选中多选列表框获取指定条目的选中状态：int select = SendMessage (hwndList, LB_GETSEL, index, 0);select非0则选中，0则没选中
多选列表框获取当前选中的条目个数：int sel_count = SendMessage (hwndList, LB_GETSELCOUNT, 0, 0L);多选列表框获取当前选中的条目索引：int* sel_items;sel_items = alloca (sizeof(int)*sel_count);SendMessage (hwndList, LB_GETSELITEMS, sel_count, sel_items);
查找含有指定字符串的条目：模糊匹配：int index = SendMessage (hwndList, LB_FINDSTRING, (LPARAM)string);精确匹配：int index = SendMessage (hwndList, LB_FINDSTRINGEXACT, (LPARAM)string);
4. 设置和获取复选框状态
获取指定条目的复选框状态：int status = SendMessage (hwndList, LB_GETCHECKMARK, index, 0);返回值：CMFLAG_CHECKED 选择状态CMFLAG_PARTCHECKED 部分选择状态CMFLAG_BLANK 未选择状态LB_ERR 没有找到指定条目设置指定条目的复选框状态：int ret = SendMessage (hwndList, LB_SETCHECKMARK, index, (LPARAM)status);返回值：LB_OKAY 成功LB_ERR 没有找到指定条目
5. 设置指定条目加粗显示
int ret = SendMessage (hwndList, LB_SETITEMBOLD, index, (LPARAM)status) ;参数：status为1则加粗，0则正常显示
6. 自定义排序方式
static int my_strcmp (const char* s1, const char* s2, size_t n);SendMessage (hwndList, LB_SETSTRCMPFUNC, 0, (LPARAM)my_strcmp);
7. 附加数据
设置附加数据：int addDataSendMessage(hwndList , LB_SETITEMADDDATA, index , addData);获取附加数据：int addDataaddData = SendMessage(hwndList , LB_GETITEMADDDATA, curSel, 0);
8. 设置和获取条目高度
设置条目高度：SendMessage(hwndList , LB_SETITEMHEIGHT, 0, (LPARAM)height);获取条目高度：int height = SendMessage(hwndList , LB_GETITEMHEIGHT, 0, 0);
通知
1. 具有 LBS_NOTIFY 风格的列表框可能产生的通知消息
LBN_ERRSPACE 内存分配失败。
LBN_SELCHANGE 单项选择列表框的当前选择项发生变化。
LBN_CLICKED 用户在列表框某条目上单击了鼠标左键。
LBN_DBLCLK 用户在列表框某条目上双击了鼠标左键。
LBN_SELCANCEL 用户取消了某个条目的选择。
LBN_SETFOCUS 列表框获得了输入焦点。
LBN_KILLFOCUS 列表框失去了输入焦点。
LBN_CLICKCHECKMARK 用户单击了条目的检查框。
LBN_ENTER 用户在列表框中按下 ENTER 键
2. 如果调用SetNotificationCallback函数设定了列表框控件的通知回调函数，则控件不会向父窗口发送 MSG_COMMAND 通知消息，而是会直接调用设定的通知回调函数
