CreateProcess with Resource of executable, not the Filename

When I want my program to run an executable file located in his resource, I will do the following:

Find the resource -> FindResource.
Load the resource -> LoadResource.
Lock the resource -> LockResource.
Create the executable file -> CreateFile.
Write the executable file -> WriteFile.
Run the executable -> CreateProcess.

Works like a charm.

But with the PlaySound function you can play a sound with the resource of the sound, using find, load, lock resource and using the returned value of LockResource as pszSound for the PlaySound function (and setting hmod to the handle of the executable with the resource and fdwSound to SND_RESOURCE).

My question: Is there a way to run the executable using CreateProcess without writing the resource of the executable to the hard disk and running it by the written file name but running the executable with only the resource of the executable and not the filename?

Thanks in advance, Ktulu.

It's just a multiple process program in one executable, there's nothing too strange about it.

When I don't need to create and write the file to the hard disk but just use the resource in the memory, that will work faster.

If you have a windows app for the looks and a command line app to work cross platform, the windows app as parent process and the command line as child process.

Command line programs can still create windows, you know.

What you want to do is going to be challenging to implement because it would require mimicing most of the Win32 PE loader built into Windows. You could possibly load the child's PE image stored in a resource into the parent's process space, providing that you ensure that the DLLs that it requires are loaded and patch the functions in the import table yourself, etc. That's waaaaaaaay beyond anything I've ever done though.

Executable packers like UPX work this way, I believe.
