The executable *can* be run from a different directory.
(ex if you type: "\html\html.exe" or if the executable is in the dos' PATH.)

To find the real directory of the executable look at argument argv[0] that
is passed to the program.

This little program will print the entire path of the executable (including
filename):

void main(int argc, char **argv)
{
	puts(argv[0]);
}

To find the config-file all you have to do is to split the path, exchange
the filename and merge it again.
