Data cant be displayed in edit control when we are execute the dialog box After opening the .csv file.

Main Requirement is:

the result which are showing in Dialog box will be changed when we updates the columns which are presented in .csv file at a time (i.e @Run time).

What I have tried:

Am trying to display the strings in given edit boxes with using following sample code:

CStdioFile file;            // access the entire given file
CString cstrLine, Temp;     // Reading the entire row at a time from excel sheet

if (file.Open(L"Data.csv", CFile::shareExclusive | CFile::typeText))    // L ---- 
                                                                      //Multybyte type
{

  while (file.ReadString(cstrLine))
  Temp = cstrLine;
  cstrLine = Temp;         // Reading the last Row every time

  int i = 0;

  for (CString sItem = cstrLine.Tokenize(_T(","), i); i >= 0; sItem = 
                                                       cstrLine.Tokenize(_T(","), i))
  {
	sItem.Trim();  // For trimming extra spaces
	str.Add(sItem);
  }

  m_csName = str.GetAt(0);  //0 means Column 1,s data
  m_csSurName = str.GetAt(1); // 1 means Column 2's data    /* of particular row in 
                                                             Excel sheet */ 
  m_csAge = str.GetAt(2); // 2 means Column 3's data

  UpdateData(FALSE); // Variable 2 Control

  file.Close();
}

But I want following requirement: i.e.,

"the result which are showing in Dialog box (In Edit Boxes) will be changed when we updates the columns which are presented in .csv file at a time (i.e @Run time)."
