Include the Binary Files in Your Source Code

June 6, 2012 No Comments algorithms, assembly language, implementation, php, python, technical, tools / utilities

Sometimes, you might want to wrap a binary file (image, executable) in your source code, to eliminate the hassle when deploying your application. You might consider using resource file (*.rc) to build a *.res file which can be finally staticlly built into the executable.

Here is another way to have the data embeded into your application: translate the data into the source code byte array.

For example, in C++, you can have an byte array defined as follows.

unsigned char data[] = { 0x01, 0x02, 0x03, ... };

Below is a python script that easily converts the binary data or string into byte array, in Assembly, Pascal, PHP and C/C++ format. You can also download the file here: data.py

In the future, more languages can be added easily. Maybe, if I have time, I will also put this online by creating a PHP page. The sample usage is given below:
