how to delete the record from the c++

1) Open existing file using CStdioFile for reading
2) Open a new file with temporary name for writing
3) Read first file and copy line by line to second file, skipping lines you want to delete
4) Close both files when reached the end of first file
5) Delete the first file
6) Rename 2d file into the old file's name.

Liberally sprinkle some error handling (like checking that second file is ok before deleting the first one)
