Want to read a txt file

  Thanks, but I am writing MFC codes only. Do you know how to do it in MFC library

  Yeah, I used CStdioFile object and ReadString() as follow:

  CString str;

  CStdioFile Ftest;

  Ftest.Open("test.txt",CFile::modeRead|CFile::modeCreate);

  Ftest.ReadString(str);

  but the code stopped from running with ASSERTION FAILURE message while I debug. Any idea

  Thanks.

  Then you can use the CStdioFile class and ReadString method. It will give you a CString that you can use the Tokenize method to extract words from.

  Would you mind sharing the assertion message

  
  

• CalgaryDataGirl

  Ftest.Open("test.txt",CFile::modeRead|CFile::modeCreate);

   

  Shoudn't this be:

  Ftest.Open("test.txt"), CFile::modeRead);

   

  with your code it seems to me that you want to open a file readonly, but with CFile::modeCreate you truncate the file to 0 bytes (equals empty the file).

   

  Correct me if i'm wrong though.

  You could use the TextReader and the ReadLine method to read a line. For each line read you can split it on the space character to get an array of words.
