Read JPEG file

[shakumar_22]

Hi I want to Read the JPEG file in the CFile or CStdioFile format. I used to Write and read ".doc",".xt" file format by CStdioFile file1; file1.m_pStream=fopen("d:/newfile1.doc","a+"); file1.WriteString(L"hai"); file1.Close(); now i want to Read and Write the JPEG formated file.Some of them said read file in Binary format, but i dont know how to read in binary format. Give your suggestion to Read and Writeing of jpeg file format regards shakumar

I think you must read stream fundamentals. fstream fs; fs.open("file.txt",ios::bin); // not sure about bin or binary. Search in C++ books, msdn does not have good documentation about streams.

Why use this? there is an open function for CStdioFile and CFile. file1.Open("d:/newfile1.doc",CFile::modeRead|CFile::modeWrite); There are some other flags also for opening. you can use the same for opening JPEG files. But what you gonne do by reading row JPEG data?

You havent understand and I guess read the documentation of the CStdioFile class. Read this first and do your homeworks at home.:mad:

:) Your idea is not bad. you dont have to do any special handling for transfering JPEG file. Follow the same steps you followed for doc and other files.

See here for the difference between binary and text files. That said, consult MSDN for the distinction between CFile and CStdioFile.
