Pay attention to the head to modify

 
M_List. InsertColumn (0, "serial number", LVCFMT_LEFT, 60). 
M_List. InsertColumn (1, "name", LVCFMT_LEFT, 300); 
M_List. InsertColumn (2, "weight", LVCFMT_LEFT, 300); 
//Modify the name of the Item 1 
HDITEM HDITEM; 
ZeroMemory (& amp; HdItem, sizeof (hdItem)); 
HdItem. Mask=HDI_FORMAT | HDI_LPARAM; 
HdItem. FMT=HDF_CENTER | HDF_OWNERDRAW; 
HdItem. LParam=(long) "name"; 
CHeaderCtrl. * pHead=m_List GetHeaderCtrl (); 
PHead - & gt; SetItem (1, & amp; HdItem);
