在虚拟listctrl中，LVIF_TEXT，LVIF_IMAGE对应文本和图标，哪个对应checkbox，并怎样设置checkbox,下面是文本和图标的代码，checkbox的代码怎样写
if(pItem->mask && LVIF_TEXT)
{
_variant_t Index, TheValue;
Index.vt = VT_I2;
Index.iVal = pItem->iSubItem;
TheValue = m_pRecordset->Fields->GetItem(Index)->Value;
if(TheValue.vt != VT_NULL)
{
CString str;
str = (char*)_bstr_t(TheValue);
str.TrimLeft();
str.TrimRight();
char Buffer[1024];
memset(Buffer, 0, 1024);
strcpy(Buffer, str);
pItem->pszText = Buffer;
}
}
if(pItem->mask && LVIF_IMAGE)
{
if(pItem->iItem % 2 == 0)
pItem->iImage = 0;
else
pItem->iImage = 1;
}
if(pItem->mask && LVIF_TEXT)
{
_variant_t Index, TheValue;
Index.vt = VT_I2;
Index.iVal = pItem->iSubItem;
TheValue = m_pRecordset->Fields->GetItem(Index)->Value;
if(TheValue.vt != VT_NULL)
{
CString str;
str = (char*)_bstr_t(TheValue);
str.TrimLeft();
str.TrimRight();
char Buffer[1024];
memset(Buffer, 0, 1024);
strcpy(Buffer, str);
pItem->pszText = Buffer;
}
}
if(pItem->mask && LVIF_IMAGE)
{
if(pItem->iItem % 2 == 0)
pItem->iImage = 0;
else
pItem->iImage = 1;
}

不是让你看结构体，看结构的说明文档

typedef struct _LVITEM {
UINT mask;
int iItem;
int iSubItem;
UINT state;
UINT stateMask;
LPTSTR pszText;
int cchTextMax;
int iImage;
LPARAM lParam;
#if (_WIN32_IE >= 0x0300)
int iIndent;
#endif
} LVITEM, FAR *LPLVITEM;
楼上的大侠，LVITEM结构没有State Image这个，有什么可以参考的代码吗？

CheckBox实际上就是State Image。State Image的设置去看LVITEM结构的文档。

1 State Image的Index实际上就是Item State的一部分(高8字节)

在使用数据自绘的LISTCTRL中CHECKBOX都显示不出来

注意，check并不是ListCtrl的基本属性，所以也不包含LVITEM，所以都是独立处理

GetCheck和SetCheck，在显示的时候透过nItem来设置
