MFC combobox 添加CImageList 列表，列表内容显示不出来或显示不全或出现乱码怎么回事？如何解决？

CImageList imagelist

#define IDI_ICON1 105

void CMainWindow::OnAddItem()

{

imagelist.Create(32, 32, ILC_COLOR32 | ILC_MASK, 2, 1);

imagelist.Add(AfxGetApp()->LoadIcon(IDI_ICON1)); //IDI_ICON1是图标ID

imagelist.Add(AfxGetApp()->LoadIcon(IDI_ICON1));

combobox.SetImageList(&imagelist);

combobox.AddString(L"123", 0);

combobox.AddString(L"456", 1);

combobox.SetCurSel(1);

m_listBox.AddString(_T("one"));

CString str1, str2;

int n;

for (int i = 0; i < combobox.GetCount(); i++)

{

n = combobox.GetLBTextLen(i);

combobox.GetLBText(i, str1.GetBuffer(n));

str1.ReleaseBuffer();

str2.Format(_T("item %d: %s\r\n"), i, str1.GetBuffer(0));

AFXDUMP(str2);

}

}
