在C ++中的.exe应用程序中包含文件（dll，txt等）

Question

I made a program written in C++ that uses many files, like .dll or .png. The program and the files are in the same directory. Is it possible including files in the .exe application? So that I only need the .exe file to run the program.

Answer 1

Ah, yes. The answer is writing all the files you need, contained in a zip file, at the end of the executable you're running. Here's how: Part 1 (writing to the executable) and Part 2 [broken link] (reading from the executable). It's fun stuff; good question.

Note that you can't do this for DLL files - they must either be in the same directory as the executable or installed on the machine.

Answer 2

Interesting question and answer.

I did it a long time ago by putting all the files inside the .exe as resources, and then extracting them all using the following procedure:

HRSRC hResInfo = FindResource(NULL, MAKEINTRESOURCE(MY_RESOURCE_ID), MY_RESOURCE_TYPE);
HGLOBAL hRes = LoadResource(NULL, hResInfo)
LPVOID lpData = LockResource(hRes);
HANDLE hFile = CreateFile(....)
WriteFile(hFile, lpData, SizeOfResource(NULL, hResInfo), ...);
CloseHandle(hFile)

The problem with my implementation was that I had to recompile the .exe everytime a new file was added (which happened only once or twice, luckily), but it's good to know how does it work under the hood.
