There are lots of answer about simply save it as const data or say converting it to binary data without details.
I have seen this: How to embed a file into an executable?
I do not prefer converting config file into const data.
How could I embed the config file inside the exe when compiled but not next to the exe.
Detailed steps are needed.
A Windows-specific method is to embed the config file into the executable as a resource:
Define an identifier for the resource in some header file, say
#define CONFIG_FILE_RESOURCE_ID 1
Add a .rc file to your project with the following lines in it:
#include "resource.h" CONFIG_FILE_RESOURCE_ID RCDATA "config.txt"
config.txt is the name of the file that will be embedded.
RCDATA is the type of resource (custom binary data).
Alternatively, if your version of Visual Studio comes with a resource editor, you could use it.
To read the resource from within your program, you must:
FindResource(NULL, MAKEINTRESOURCE(CONFIG_FILE_RESOURCE_ID), RT_RCDATA)to get a resource handle.
LoadResource(NULL, hrsrc)to convert the resource handle
SizeofResourcefunctions to obtain a pointer to the data and the size of the embedded file.
You may have to supply actual module/instance handles instead of
NULL, especially if your code is inside a DLL.
