关于KODAK控件问题！

请问各位老师，如何通过CFileDialog对话框用KODAK控件显示图片。CImgEdit  m_ctrlPicture;  \\CImgEdit为KODAK控件
void AddDLG::OnButton1()
{

CString  FilePathName;

    CFileDialog dlg(TRUE,NULL,NULL,0,"bmp Files (*.bmp)|*.bmp||",this);
     if(dlg.DoModal()==IDOK)
      {
  FilePathName=dlg.GetPathName();
          m_ctrlPicture.SetImage("FilePathName");
          m_ctrlPicture.Display();
}
}以上代码总报错，请问错在那里？
