how to edit or see the source code for dll files -

-

i have dll file old game(age of empires) want edit file or see source code. tried reflector toll , others, without result

so, 1- how can edit or see dll file??
2- can know in language file written?

  1. it's sort of difficult. mean can @ file hex editor, it's not going nice. however, can use 3rd party tools in order info can dll:

    • dependency walker - useful dlls dll depends on (and functions need there), exported functions, ...

    • pe explorer - nice tool (i'm not saying it's best) lists lots of info dll (sections, resources, ...) , has disassembler (this reverse engineers dll , displays in form of assembly code). if understand assembly code can modify (by modifying corresponding bytes in dll), that's experts only

  2. most written in c. tools listed can tell more. can hex editor @ dll, inside there might references source files

if dll has dependencies in form of msvcr###.dll (# sign placeholder digit) or vcruntime###.dll it's c, if has msvcp###.dll it's c++ (created vstudio).
