read-write

问题 Using the hex editor HxDen one can read (and edit) the bytes on the hard drive or a USB key or the RAM. That is, one can read/change the first byte on the hard disk. I understand how to read the bytes from a file using C++, but I was wondering how one might do this for the hard disk. To make it simple, given a positive integer n, how can I read byte number n on the hard drive using C++? (I would like to do C++, but if there is an easier way, I would like to hear about that.) I am using MinGW

问题 This question already has answers here : Python is adding extra newline to the output (5 answers) Closed 4 years ago . I have this little problem. If i create a list from the content of a txt file and print it row by row there are huge spaces between these outputs.

问题 I am using Qt5 on Windows 7. In my current project I open a binary file in order to populate it with data coming from a TCP socket. Normally, after the file is populated, I close it and another application will read this binary file for further processing. Well, the problem is: The writing operation takes about 4-5 seconds (or even more) so I need to find a way to prevent the other application from reading from the binary file until the file is completely populated ... Here below is the code
