函式原型：
int InsertItem( const LVITEM* pItem );
int InsertItem( int nItem, LPCTSTR lpszItem );
int InsertItem( int nItem, LPCTSTR lpszItem, int nImage );
int InsertItem( UINT nMask, int nItem, LPCTSTR lpszItem, UINT nState, UINT nStateMask, int nImage, LPARAM lParam );
其中，nItem是控制項中行的索引 、lpszItem是控制項頭的名字。
一般我們用的比較多的是第二種和第三種,其中第三種是建立一個帶有頭標的項。
作用:
用於MFC中CListCtrl控制項加入列表項。
參數:
第一個參數是節點名
第二個參數是樹節點未選中時使用的圖示下標，
第三個參數是樹節點選中時使用的圖示下標，
第四個參數是本節點的父節點，第二、三個參數都是針對樹的圖像列表而言的。CImageList* SetImageList( CImageList * pImageList, int nImageListType );給樹插入圖像列表.
Return Value
The index of the new item if successful or -1 otherwise.
Parameters
pItem
Pointer to anLVITEM structure that specifies the item’s attributes, as described in the Platform SDK.
nItem
Index of the item to be inserted.
lpszItem
Address of a string containing the item’s label, or LPSTR_TEXTCALLBACK if the item is a callback item. For information on callback items, see CListCtrl::GetCallbackMask.
nImage
Index of the item’s image, or I_IMAGECALLBACK if the item is a callback item. For information on callback items, see CListCtrl::GetCallbackMask.
nMask
The nMask parameter specifies which item attributes passed as parameters are valid. It can be one or more of the mask values described inLVITEM structure in the Platform SDK. The valid values can be combined with the bitwise OR operator.
nState
Indicates the item's state, state image, and overlay image. See the Platform SDK topics LVITEM for more information andList View Item States for a list of valid flags.
nStateMask
Indicates which bits of the state member will be retrieved or modified. See LVITEM in the Platform SDK for more information.
nImage
Index of the item’s image within the image list.
lParam
A 32-bit application-specific value associated with the item. If this parameter is specified, you must set the nMask attribute LVIF_PARAM.
Remarks
Inserts an item into the list view control.
Example
// The pointer to my list view control.
extern CListCtrl* pmyListCtrl;
CString strText;
int nColumnCount = pmyListCtrl->GetHeaderCtrl()->GetItemCount(); // Insert 10 items in the list view control.
for (int i=0;i < 10;i++) {
strText.Format(TEXT("item %d"), i); // Insert the item, select every other item.
pmyListCtrl->InsertItem( LVIF_TEXT|LVIF_STATE, i, strText, (i%2)==0 ? LVIS_SELECTED : 0, LVIS_SELECTED, 0, 0); // Initialize the text of the subitems.
for (int j=1;j < nColumnCount;j++) {
strText.Format(TEXT("sub-item %d %d"), i, j);
pmyListCtrl->SetItemText(i, j, strText); }
}
