1. 在 OnInitDialog 中加入
GetDlgItem(IDC_MY_PIC)->ModifyStyle ( SS_TYPEMASK, SS_OWNERDRAW );
2. 在butto 按钮中加入以下，可以显示多中类型的图片资源
void CDlgpicDlg::OnTest()
{
// TODO: Add your command handler code here
CFileDialog fileDlg(TRUE,NULL,NULL,
OFN_ALLOWMULTISELECT,
_T("Picture Files (*.bmp *.ico *.jpg)|*bmp;*.ico;*jpg|All Files (*.*)|*.*||"),
AfxGetMainWnd());
CString pathName;
if(fileDlg.DoModal ()==IDOK)
{
POSITION mPos=fileDlg.GetStartPosition();
while(mPos!=NULL)
{
pathName=fileDlg.GetNextPathName(mPos);
if(m_pict.LoadPicture(pathName.GetBuffer(pathName.GetLength())))
{
// 防止有透明图片，消除已有的图片信息
CPaintDC dc(this); // device context for painting
CRect rc;
GetDlgItem(IDC_MY_PIC)->GetWindowRect(&rc);
dc.FillSolidRect(rc, RGB(0, 0, 0));
Invalidate();
}
}
}
}
