CListCtrl 中 cchTextMax 的问题，我现在最多只能写 259 个字符到 item 中，把cchTextMax的值赋得再大也没用

38062708 2005-11-02 04:13:04
如题，请各位试试看，解决了请告诉我

另问，怎样找到 CListCtrl 中函数的原形？ 如 SetItem() 的函数原型？

char szTmp[300];
memset(szTmp, '1', 298);
szTmp[298]='a';
szTmp[299]='\0';

LVITEM lvi;
lvi.mask = LVIF_TEXT;
lvi.pszText = szTmp;
ListView_InsertItem(m_hWnd, &lvi);

laiyiling(陌生人 V3.0●猎分) :

我以前搜到过他的 BLOG ，他是读不出长字串，我现在是显示不出 259 长度以上的字串。
我需要看到 至少 300 长度的字串。

BOOL CListCtrl::SetItemText(int nItem, int nSubItem, LPCTSTR lpszText)
{
ASSERT(::IsWindow(m_hWnd));
ASSERT((GetStyle() & LVS_OWNERDATA)==0);
LVITEM lvi;
lvi.iSubItem = nSubItem;
lvi.pszText = (LPTSTR) lpszText;
return (BOOL) ::SendMessage(m_hWnd, LVM_SETITEMTEXT, nItem, (LPARAM)&lvi);
}

函数中无长度变量，惨！！

另外，他重载

CString CListCtrl::GetItemText(int nItem, int nSubItem) const

函数还不如用下一个函数

CString CListCtrl::GetItemText(int nItem, int nSubItem) const

直接就有长度的，呵呵

导出CListCtrl控件到Excel文件
CListCtrl获得列的属性可以使用BOOL CListCtrl::GetColumn( int nCol, LVCOLUMN* pColumn )，nCol为需要获得获得属性值的列序号，pColumn 为 LVCOLUMN 结构体的指针。LVCOLUMN结构体中的 UINT mask 作为输入，决定返回哪些属性的值，如果 mask 的值包含 LVCF_TEXT ，则需要将字符串缓存的首地址指针置入结构体中的 LPTSTR pszText; 变量，缓存大小置入 int cchTextMax; 变量

        VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
        向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
