    Hello, I need to print last 20 characters of string, but only whole words. Delimiter is a space "". Let's consider this example: string="The quick brown fox jumps over the lazy dog" echo $string | tail -c20 returns s over the lazy dog. And I need it to return over the lazy dog instead. Do you know how to accomplish that? Thanks!

  • Query MySQL with unicode char code.

    - by Ben
    Hi, I have been having trouble searching through a MySQL table, trying to find entries with the character (UTF-16 code 200E) in a particular column. This particular code doesn't have a glyph, so it doesn't seem to work when I try to paste it into my search term. Is there a way to specify characters as their respective code point instead for a query? Thanks, -Ben

  • How to code a keyboard button to switch between 2 modes?

    - by le.shep20
    Hi! i'm doing a project, i'm not going to details but i will simplify my idea, i'm using Morse Code ( dot and dash) and i have 2 methods: convert_MorseToChar() and Convert_MorseTonum() in the convert_MorseToChar() method there is swich to compare the input from a user which will be Morse codes and mapping it to characters: private String convert_MorseToChar(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "a" break; Case "-...": MorsetoChar = "b" break; Case "-.-.": MorsetoChar = "c" break; Case "-..": MorsetoChar = "d" break; Case ".": MorsetoChar = "e" break; } } and the other method Convert_MorseToNum(), ues the SAME combinations of Morse codes but mapping them to numbers: private String Convert_MorseToNum(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "1" break; Case "-...": MorsetoChar = "2" break; Case "-.-.": MorsetoChar = "3" break; Case "-..": MorsetoChar = "4" break; Case ".": MorsetoChar = "5" break; } } now the senario is: there are 2 Textbox, one the user will write Morse codes in it and the other is for the output. The user will write dot "." and dash "-" from the keyboard and press Enter then the program will go to ONE of the 2 methods to convert the Morse codes. Now what tells the program where to go to convert?? my question is: I want to create mode key to swich between 2 modes: MorseTochar and MorseToNum. i want the down arrow key to act like a mode, when a user press the down arrow then it the program will be in MorseToChar mode, when ever the user input the program directly use the method convert_MorseToChar to convert to characters. and when the user press the down arrow agian, the prohram will swich to MorseToNum mode here when ever the user input as morsecode, the program will directly use the method Convert_MorseToNum() to convert to numbers. HOW I CAN DO THAT Pleaaaas!!! help me! Please excuse my English, English is not my native language :)

  • What is the email subject length limit?

    - by Scott Ferguson
    How many characters are allowed to be in the subject line of Internet email? I had a scan of The RFC for email but could not see specifically how long it was allowed to be. I have a colleague that wants to programmatically validate for it. If there is no formal limit, what is a good length in practice to suggest? Cheers,

  • CSS files that don't end with .css

    - by Yongho
    Is there a disadvantage to using a dynamic Python file to generate the CSS for a webpage? I'd like computers with an administrator cookie to show special admin panel CSS, and show regular CSS for all other users. I'm planning to use: <link rel="stylesheet" href="/css.py" type="text/css" />

  • Difference between WinMain and wWinMain

    - by Sherwood Hu
    The only difference is that Winmain takes char* for lpCmdLine parameter, while wWinMain takes wchar_t*. On Windows XP, if an application entry is WinMain, does Windows convert the command line from Unicode to Ansi and pass to the application? If the command line parameter must be in Unicode (for example, Unicode file name, conversion will cause some characters missing), does that mean that I must use wWinMain as the entry function?

  • How to check if string is a valid XML element name?

    - by xsaero00
    I need a regex or a function in PHP that will validate a string to be a good XML element name. Form w3schools: XML elements must follow these naming rules: Names can contain letters, numbers, and other characters Names cannot start with a number or punctuation character Names cannot start with the letters xml (or XML, or Xml, etc) Names cannot contain spaces I can write a basic regex that will check for rules 1,2 and 4, but it won't account for all punctuation allowed and won't account for 3rd rule \w[\w0-9-]

  • trouble with boost::filesystem::wrecursive_directory_iterator

    - by Dogmatixed
    I'm trying to write a program to help me manage my iTunes library, including removing duplicates and cataloging certain things. At this point I'm still just trying to get it to walk through all the folders, and have run into a problem: I have a small amount of Japanese music, where the artist and/or album is written in Japanese characters. Because of how iTunes arranges things in its library the directories contain these characters. "shouldn't be a problem, though." I thought, because the boost::filesystem library has a wide character version of its recursive iterator. but when I actually try to use it, it seems to completely stop when it hits the first Japanese char. complete stop as in it doesn't finish printing the line, no carriage return or anything. now, I'm still pretty new to programming, so I'm assuming it's my mistake, anyone know why this is happening? here's what I think is the relevant code: fs::wrecursive_directory_iterator end_it; int i; try { for(fs::wrecursive_directory_iterator rec_it(full_path); rec_it != end_it; ++rec_it) { for(i = 0; i < rec_it.level(); i++) { out << "\t"; } out << rec_it->string() << std::endl; } } catch(std::exception e) { out << "something went wrong: " << e.what(); } and from my output file, minus some of the path: /Test Libs/Combine /Test Libs/Lib1 /Test Libs/Lib1/02 Too Long.m4a /Test Libs/Lib1/03 Like a Hitman, Like a Dancer.mp3 /Test Libs/Lib1/A Certain Ratio /Test Libs/Lib1/A Certain Ratio/Beyond Punk! /Test Libs/Lib1/A Certain Ratio/Unknown Album /Test Libs/Lib1/A Certain Ratio/Unknown Album/Do The Du.mp3 /Test Libs/Lib1/A Certain Ratio/Unknown Album/Shack Up.mp3 /Test Libs/Lib1/ finally, what I expect: /Test Libs/Combine /Test Libs/Lib1 /Test Libs/Lib1/02 Too Long.m4a /Test Libs/Lib1/03 Like a Hitman, Like a Dancer.mp3 /Test Libs/Lib1/A Certain Ratio /Test Libs/Lib1/A Certain Ratio/Beyond Punk! /Test Libs/Lib1/A Certain Ratio/Unknown Album /Test Libs/Lib1/A Certain Ratio/Unknown Album/Do The Du.mp3 /Test Libs/Lib1/A Certain Ratio/Unknown Album/Shack Up.mp3 /Test Libs/Lib1/??? /Test Libs/Lib1/Bring it on /Test Libs/Lib1/04 Bring it on.mp3 any thoughts? Thanks.

  • java unload static fields

    - by Alina Danila
    I have a java class that uses complex static fields which need special operations as close() so that they are safely cleaned by GC. For the initialization of static fields I use the static block. But I don't now how to unload the static field safely, so that I can call the close() method before the field is cleaned up by GC. Is there any way to unload a static field, similar to the static initialization block?

  • Get Class List for Element with JQuery

    - by Buggabill
    Is there a way in JQuery to loop through or assign to an array all of the classes that are assigned to an element? ex. <div class="Lorem ipsum dolor_spec sit amet">Hello World!</div> I will be looking for a "special" class as in "dolor_spec" above. I know that I could use hasClass() but the actual class name may not necessarily be known at the time.

  • regular expression

    - by Jeeenda
    Hi I need a regular expression that'll give me something like this part ./something\", [something.sh from something like this string ("./something\", [something.sh", ["./something\", [something.sh"], [/* 37 vars */]) is that possible? I'm having real trouble making this since there's that \" escape sequence and also that ',' character, so I cannot simply use match everything instead of these characters. I'm working on unix so it's also possible to use pipeline of few greps or something like that. Thanks for advice.

  • Tray Icons Keep On Popping Up

    - by Soo
    I have a WinForm program that checks a database for changes, and if there are any, it will open another WinForm telling the user what is happening (the popup WinForm has some special functionality making a MessageBox insufficient for this task). Each time one of these popup WinForms shows up, a new icon shows up in the system tray and does not go away even if you hover over it (this isn't a tray refresh issue). What I'm wondering is how to get the popup WinForm to display no tray icon at all.
