list control 图标显示问题

Question

CImageList m_ImageList;
m_ImageList.Create(16,16,ILC_COLOR32,2,0);
m_list.SetImageList(&m_ImageList,LVSIL_NORMAL);   
CBitmap   cBmp;
cBmp.LoadBitmap(IDB_BITMAP2); 
m_ImageList.Add(&cBmp,(255,0,255));
cBmp.DeleteObject();   
cBmp.LoadBitmap(IDB_BITMAP2); 
m_ImageList.Add(&cBmp,(255,0,255));
cBmp.DeleteObject(); m_list.InsertItem(0,"文字1",0);
m_list.InsertItem(1,"文字2",1);以上代码只能显示文字,图标怎么也显示不出来,有那位高手帮忙看看.

Answer 1

你都DeleteObject(); 不在内存中了还怎么显示

Answer 2

你怎么又是位图又是图标的，加两次以del两次，白忙啊，不能放最后去吗？

// draw tree "My Computer"
TV_INSERTSTRUCT TreeCtrlItem;
TreeCtrlItem.hParent = TVI_ROOT;
TreeCtrlItem.hInsertAfter = TVI_LAST;// don't use TVI_SORT;
TreeCtrlItem.item.mask = TVIF_TEXT|TVIF_IMAGE|
                     TVIF_SELECTEDIMAGE|TVIF_CHILDREN;//|TVIF_STATE;
TreeCtrlItem.item.pszText= m_MyComputer;
TreeCtrlItem.item.cchTextMax = MAX_PATH;
TreeCtrlItem.item.cChildren=1;// has child show "+"
//
    HRESULT hr;
LPMALLOC lpMalloc;
    hr=::SHGetMalloc(&lpMalloc);
    if (FAILED(hr)) return TRUE;
// get pidl of "My Computer"
    LPITEMIDLIST  lpidl=NULL;  // pidl of "My Computer"
hr=SHGetSpecialFolderLocation(NULL,CSIDL_DRIVES,&lpidl);
    if (FAILED(hr)) return TRUE;
// icons and "My Computer"
SHFILEINFO    sfi;
SHGetFileInfo((LPCSTR)lpidl,0,&sfi,sizeof(SHFILEINFO),SHGFI_PIDL | 
SHGFI_DISPLAYNAME | SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
TreeCtrlItem.item.iImage = sfi.iIcon;
_tcscpy(m_MyComputer,sfi.szDisplayName);
//
SHGetFileInfo((LPCSTR)lpidl,0,&sfi,sizeof(SHFILEINFO),SHGFI_PIDL | 
SHGFI_SYSICONINDEX | SHGFI_SMALLICON | SHGFI_OPENICON);
TreeCtrlItem.item.iSelectedImage = sfi.iIcon;
// insert root
HTREEITEM hTreeItem1 = m_Tree.InsertItem(&TreeCtrlItem);
TreeCtrlItem.hParent = hTreeItem1;

Answer 4

DeleteObject()方法放到哪个位置,还是将这个方法去掉,两种方法都试了还是不行,能不能说的具体点

Answer 5

这样产生imagelist：
CBitmap bitmap;
UINT nID;
// images 
ImagelistList.Create(16,16,ILC_COLOR8 | ILC_MASK,6,4); 
//
Imagelist.Create(16,16,ILC_COLOR8 | ILC_MASK,6,4); 
for (nID=IDB_DIR;nID<=IDB_09;nID++) //0-9  
{
bitmap.LoadBitmap(nID);
Imagelist.Add(&bitmap,(COLORREF)0xFFFFFF);
bitmap.DeleteObject();
}
LeftTree.SetImageList(&Imagelist,TVSIL_NORMAL);
