I have a sequence of bytes that I have to search for in a set of Binary files using Java. Example: I'm searching for the byte sequence DEADBEEF (in hex) in a Binary file. How would I go about doing this in Java? Is there a built-in method, like String.contains() for Binary files? ...
Is there a BinaryReader in C++ to read data written from a BinaryWriter in C#?
I've written several ints, char[]s and the such to a data file with BinaryWriter in C#. Reading the file back in (in C#) with BinaryReader, I can recreate all of the pieces of the file perfectly. However, attempting to read them back in with C++ yields some scary results. I was using fstream to attempt to read back the data and the ...

fread terminating mid-read at null values. Also reading in garbage past expected data.
I am reading in pieces of a binary file using a FILE object in C++. Here is the fseek and corresponding fread call: fseek(fp, startLocation, SEEK_SET); fread(data, m_sizeOfData, 1, fp); m_sizeOfData ends up being an integer greater than 400 thousand. This appears that it should read all 400 thousand+ bytes from the binary file into ...

JPG+Zip File Combination Problem with Zip Format
Hopefully you've heard of the neat hack that lets you combine a JPG and a Zip file into a single file and it's a valid (or at least readable) file for both formats. Well, I realized that since JPG lets arbitrary stuff at the end, and ZIP at the beginning, you could stick one more format in there - in the middle. For the purposes of thi...
