c# - What is the most elegant way to implement GetTextAfterMarker() -

-

I have one more old work from my C # 1 day, what would be one more great way to write this: 

  // Method: Text goes into a string in front of a marker, if the marker is not there, then return the empty string / example: GetTextAfterMarker ("documents / jan / letter043.doc" GiftTextAfterMarker ("letter043.doc", "/") / / rank: 8 public static string GetTextAfterMarker (string line, string marker) It is {string r = ""; Int pos = line.IndexOf (marker); If (pos! = -1) {r = line.Substring (pos + (marker.Length), line.Length-pos- (marker.Length)); } Other {r = ""; } Return R; }

I've got some strange names, given that the text should be shown First marker but it works the same, I think (I have taken the liberty to change the name): 

  public stable string GetTextBeforeMarker (string line, String marker) {if (line == empty) {fix minimum to new logic ("line"); } If (marker == faucet) {new logic: NullException ("marker"); } String result = line.Split (new string [] {marker}, string split option. A) [0]; Return line Excel (result)? String Empty: Results; }

Explanation: Divide the string into an array as a segment of the marker, if the first element of the result is the same as the input, the marker was not in the string, so we have an empty string Return, otherwise we return the first element (which is the text of the first event of the marker).

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...

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...
