java - Dealing with end of 'file' using BufferedReader.read() -

-

I have a client server program that should send the contents of the file as a string and The problem is that how to eliminate the loop in which the BufferedReader.read method is the I code: 

  while ((c = in.read ())! = -1) {fw .write ((four) c); System.out.print ((four) c); }   
 But since it uses sockets, it never reaches 1 until the socket closes. Unless I can not find an end segment to reach the loop, are there any special characters?  
 went with:  
  while ((line = in.readline ())! = Null & amp;; line.equals (BasicProtocol.SENDING_FILE_DONE)) < / Code>  
 where SENDING_FILE_DONE is a string that has been added at the end of the stream. There is not a good way to do this, but in this manner (I believe) when the data string should be.   
 
 
 
 I have a client server program, which is the content of a file as a string   
 Why? Bad idea It should be sent as a byte. Otherwise you are running the risk of data corruption. There is a problem deciding to end the loop with  
 
 and  BufferedReader.read ()  method . I  
     
  1.  You should not use  BufferedReader , to avoid the notion that you should use the  BufferedInputStream  to join the file.  
  2.  You should have sent a file size in front of the file, and you should read the file size, then the loop should be read as long as you do not read too many bytes properly, or you have to send the file The latter socket should be closed.

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
