I used EnumProcessModules() function and then retrive
list of modules, but I cant reach to the handle of current file
(file1.txt) opened by process or just list of all files(handles)
opened by process,

Can you please help me with this?

It's specific for each application.
The normal way to enumerate the handle table is with
NtQuerySystemInformation() to get handles for each PID,
but programs like Notepad or Notepad++ close the handles.
(you can enumerate tabs of the Tab control of Notepad++ for example...)

google for
NtQuerySystemInformation NtQueryObject

Best hit:

Probem: Before calling NtQueryObject you don't know
the type of handle. But if you call NtQueryObject
for a waiting pipe then it will not return until
the pipe stops waiting.
Seems a driver is required to overcome this...

You use EnumProcessModules? I think this function is only used to
retrieve module images it loaded into its process memory space. Waht i
said modules are different with the files it opened. Dll files are common.

btw, why i use EnumProcessModules function will get an error
code:ERROR_GEN_FAILURE?
