Please read http://www.codeproject.com/Messages/2922875/HOW-TO-ASK-A-QUESTION.aspx[^]. You generate a text file by adding code to your program to collect the information to go in the file and writing it there. See http://msdn.microsoft.com/en-gb/library/windows/desktop/aa365747(v=vs.85).aspx[^] and http://msdn.microsoft.com/en-us/library/22z6066f(v=vs.100).aspx[^].

And? Do you have a question?

You should not use fprintf to write binary data (.wav files); use WriteFile as I suggested in my previous post. You can use fprintf to create a text file containing the names of all your files.

CPallini

Your program could simply write its output to console (e.g. using printf function, or cout object), then (on program invocation) you may redirect the standard output to a text file, e.g.

myprogram > myfile.txt

THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

do this WriteFile function work in ubuntu ?

mybm1

Actually without giving command I want to generate itself..that why but Thanks anyhow..

My apologies, you need fwrite[^] in Linux.

mybm1

By the way how to use this function?

CPallini

There is the documentation for the very purpose of learning function (or object) usage: Basic Input/Output at C++ reference[^]. printf at C++ reference[^].
