.net - Adding 'new' in front of the return type of C# method definition? -

-

So I recently participated in this C # statement on the job: 

  public New string Some functions (Int i) {return base.SomeFunction (i); }

I searched the web but I think I can get a better answer here.

Now, I feel that it does everything a new string returns from the same value because the call returned by base.SomeFunction (i) ... is this correct?

In addition, is this feature present in other languages ​​(especially Java)?

Edit:
In my specific case, base. Some functions are protected and not virtual Does this make a difference? Thanks

No, that means it hidden some functions If there was no method in the base class with the same signature in the base class instead of you will get a compile-time error (because you will not hide anything there) !)

See for more information. (I do not think this is a duplicate question, because instead of talking about the warning only when it is absent, what is "new".)

Duplicate Example with my answer on that question, To save clickthroughs ...

Here is an example of the difference between concealing a method and overriding it: 

  using the system; Class Base {Public Virtual Zero Override Me () {Console.WriteLine ("Base.OverrideMe"); } Public Virtual Zero HideMe () {Console.WriteLine ("Base.HideMe"); }} Category derived: base {public override zero override () {Console.WriteLine ("Derive.OverrideMe"); } Public New Zero HideMe () {Console.WriteLine ("Derived.HideMe"); }} Class Test {Static Zero Main () {Base X = New Deferred (); X.OverrideMe (); X.HideMe (); }}

Output is: 

  generated. Override base. Hydem

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

c - Linux mmap() error -

I have a memory map file, out of which I want to parse the content of the buffer. MMAP () achieves success, and I can successfully use fprintf to print the buffer content in the file. However, when I try to access Buffer as an array in my program directly, I get a partition error. Why is this happening? Here's the code: #define PTT_DUMP "/ home / druru / somefile". . Int fd_ptt_dump = Open (PTT_DUMP, O_RDONLY); Structure state struct_ptt_dump; Fstat (fd_ptt_dump, & amp; struct_ptt_dump); Printf ("\ n \ n \ t \ t \ t --- Size of dump =% d ----- \ n \ n", struct_ptt_dump.st_size); Four * membuffer; Four pid_num [100]; Four cycles [100], examples [100], CPI [100]; Int pid_index = 0; Int cycles_index = 0; Int instr_index = 0; Int cpi_index = 0; Int len ​​= (int) struct_ptt_dump.st_size; Int newline_count = 0; Int n = 0; If ((membuffer = mmap (0, struct_ptt_dump.st_size, PROT_READ, MAP_FILE | MAP_PRIVATE, fd_ptt_dump, 0)) == (caddr_t) -1) err_sys ("mm...
