There is object in my program. but i have to modify some thing in
the source code & compile & get the .obj object file.
but i don't know where is the source code (.c file).
So, is there any way we can find out in which disk it is or
who as last changed or compiled the code.
If what you are saying is that you have the object code file but no source code then you are stuffed as far as c goes. If it is a class object which is c++ and not c then you can inherit this class in a new class and add what you need or override the functions that cause problems in the original file.As far as i am aware there is no way of getting c source from a .obj file.
