c# - How do I improve the performance of code using DateTime.ToString? -

-

: 

  LoginTree Time. Toastring ("DD.MM.IHH: mm: SS: FFF")

Takes 33% of the total processing time. Does anyone have any idea about how to make it faster?

Edit: This app is used to process some binary logs and it currently takes up to 15 hours to run. So the time of 1/3 will be 5 hours.

EDIT: The application I'm using for profiling is processing approximately 17 GB of binary logs.

It is unfortunate that there is no type of .NET "formatter" type that can parse a pattern And can remember it.

If you are always using the same format, then you really want to hand-craft the formator to do this. Some on the lines of: 

  public static string formatDetermission (datetime DT) {four [] characters = new colors [21]; Write2Chars (letters, 0, dt.day); Characters [2] = '.'; Write2Chars (letters, 3, dt.Month); Characters [5] = '.'; Write2Chars (character, 6, dt.Year% 100); Character [8] = ''; Write2Chars (letters, 9, dt.Hour); Character [11] = ''; Write2Chars (letters, 12, dt.Minute); Character [14] = ''; Write2Chars (letters, 15, dt.Second); Characters [17] = ''; Write2Chars (Characters, 18, DT. Milyscand / 10); Character [20] = number (dt. millisecond% 10); Return new string (character); } Private static zero Write2Chars (four [] characters, int offset, int value) {character [offset] = digitally (value / 10); Character [offset + 1] = number (value% 10); } Private static four digit (integer value) {return (four) (value + '0'); }

It is very ugly, but perhaps it is very efficient ... definitely it's benchmark!

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...

PHP - get image from byte array -

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
