Hi,

I am having a list control - report view, with 3 columns. How can i get the column name? I tried GetColumn(). But it is not returning the value.
The code part is shown below.

LVCOLUMN lvColInfo ;	
ZeroMemory(&lvColInfo, sizeof(lvColInfo));
m_MyListCtrl.GetColumn(0, &lvColInfo);

The CListCtrl::GetColumn (MFC)[^] is the right API to use, but you should initialize your lvColInfo with the informations that you want to retrieve (see LVCOLUMN Structure (Windows)[^] for details).
Here below is a code snippet that shows you how to retrieve the name of the column:

TCHAR szName[128]; // This is the buffer where the name will be stored
LVCOLUMN lvColInfo;
ZeroMemory(&lvColInfo, sizeof(lvColInfo)); // This line is not really needed and you can remove it
lvColInfo.mask = LVCF_TEXT;
lvColInfo.pszText = szName;
lvColInfo.cchTextMax = _countof(szName);
m_MyListCtrl.GetColumn(0, &lvColInfo);

如果您需要检索文本列，则必须正确初始化LVCOLUMN结构:

If you need to retrieve the text of a column then you must properly initialize the LVCOLUMN struct:

const INT SIZE = 0x100;
TCHAR szText[SIZE];
LVCOLUMN lvColInfo ;
ZeroMemory(&lvColInfo, sizeof(lvColInfo));
lvColInfo.pszText = szText;
lvColInfo.cchTextMax = SIZE;
lvColInfo.mask = LVCF_TEXT;
m_MyListCtrl.GetColumn(0, &lvColInfo);
