I am trying to embed a large resource file (almost 4gb), its a .dat file. However i am running into issues where it throws an error
"Error reading resource 'Sx64.x-none.dat' -- 'Specified argument was out of the range of valid values.
It appears there is a limitation to the size of an embedded resource for Visual studio. Would there be a way to increase the max size? or some other work around for this? I am trying not to use a linked resource or have another file being copied around with the exe.
While in the PE format specification the SizeOfImage value is a 32 bit unsigned integer and can theoretically handle up to 4 GiB, in practice the limit for an executable file is lower. Some user here on stackoverflow has tested this behavior. However it's still possible to make an executable bigger and working (on 64 bit Windows only) but the data must be kept outside of the image sections at End Of File, so the loader won't attempt to allocate it. This is a bad practice and I suggest, as suggested by others in comments, to ship it in a separate file along with your executable.
