CFileDialog用法

 读取单幅图像

 

 

TCHAR szFilter[] = _T("图像数据(*.raw)|*.raw|所有文件(*.*)|*.*||");   

 CFileDialog fileDlg(TRUE, _T("txt"), NULL, 0, szFilter, this);   

 CString strFilePath;  
 CString strFileName;
 FILE *fp;
 char    acfilename[100] = {0};

 CString dir;
 dir = PublicObject.GetCurrWorkingDir();

 if(PublicObject.GetDR())
 {
  dir = dir+L"\\CMTCInput\\DR_MTF\\";
 }
 else
 {
  dir = dir+L"\\CMTCInput\\Mammo_MTF\\";
 }
 fileDlg.m_ofn.lpstrInitialDir = dir;

 if (IDOK == fileDlg.DoModal())   
 {   
  strFilePath = fileDlg.GetPathName(); 
  strFileName = fileDlg.GetFileTitle();
  if( (strFileName.Compare(L"AAA_Img")) == 0)      {
     m_isVerticalImage = false;
  }
  if( (strFileName.Compare(L"AAA")) == 0)   
  {
   m_isVerticalImage = true;
  }
  SetDlgItemText(IDC_EDIT_VERTICAL, strFilePath);   
  m_isVLoadOk = true;
 }  
 int nImageWith = PublicObject.GetImageWidth();
 int nImageHigh = PublicObject.GetImageHigh();
 std::fstream file(strFilePath,std::ios::in|std::ios::out|std::ios::binary);
 file.read((char*)PublicObject.m_pBImageMTFVertical,nImageWith*nImageHigh*2);
 file.close();
