  • phpMyAdmin "No database selected" MySQL

    - by user1751660
    I downloaded a MySQL backup file and promptly imported into MAMP's phpMyAdmin. I got this return: Error SQL query: -- -- Database: `mysql` -- -- -------------------------------------------------------- -- -- Table structure for table `columns_priv` -- CREATE TABLE IF NOT EXISTS `columns_priv` ( `Host` CHAR( 60 ) COLLATE utf8_bin NOT NULL DEFAULT '', `Db` CHAR( 64 ) COLLATE utf8_bin NOT NULL DEFAULT '', `User` CHAR( 16 ) COLLATE utf8_bin NOT NULL DEFAULT '', `Table_name` CHAR( 64 ) COLLATE utf8_bin NOT NULL DEFAULT '', `Column_name` CHAR( 64 ) COLLATE utf8_bin NOT NULL DEFAULT '', `Timestamp` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP , `Column_priv` SET( 'Select', 'Insert', 'Update', 'References' ) CHARACTER SET utf8 NOT NULL DEFAULT '', PRIMARY KEY ( `Host` , `Db` , `User` , `Table_name` , `Column_name` ) ) ENGINE = MYISAM DEFAULT CHARSET = utf8 COLLATE = utf8_bin COMMENT = 'Column privileges'; MySQL said: #1046 - No database selected I did not alter the .sql file at all. Any hints on how i can get this puppy going locally? Thanks!

  • Deterministic random number generator with context?

    - by user653133
    I am looking for a seeded random number generator that creates a pool of numbers as a context. It doesn't have to be too good. It is used for a game, but it is important, that each instance of the Game Engine has it's own pool of numbers, so that different game instances or even other parts of the game that use random numbers don't break the deterministic character of the generated numbers. Currently I am using rand() which obviously doesn't have this feature. Are there any c or objective-c generators that are capable of doing what I want? Best regards, Michael

  • Regex to split a string (in Java) so that spaces are preserved?

    - by david
    I need to split a string (in Java) into individual words ... but I need to preserve spaces. An example of the text I need to split is something like this: ABC . . . . DEF . . . . GHI I need to see "ABC", " . . . .", "DEF", ". . . .", and "GHI". Obviously splitting on the space character \s isn't going to work, as all the spaces get swallowed up as one space. Any suggestions? Thanks

  • Is it possible to use a back reference to specify the number of replications in a regular expression

    - by user307894
    Is it possible to use a back reference to specify the number of replications in a regular expression? foo= 'ADCKAL+2AG.+2AG.+2AG.+2AGGG+.+G+3AGGa4.' The substrings that start with '+[0-9]' followed by '[A-z]{n}.' need to be replaced with simply '+' where the variable n is the digit from earlier in the substring. Can that n be back referenced? For example (doesn't work) '+([0-9])[A-z]{/1}.' is the pattern I want replaced with "+" (that last dot can be any character and represents a quality score) so that foo should come out to ADCKAL++++G.G+. foo = 'ADCKAL+2AG.+2AG.+2AG.+2AGGG^+.+G+3AGGa4.' indelpatt = re.compile('\+([0-9])') while indelpatt.search(foo): indelsize=int(indelpatt.search(foo).group(1)) new_regex = '\+%s[ACGTNacgtn]{%s}.' % (indelsize,indelsize) newpatt=re.compile(new_regex) foo = newpatt.sub("+", foo) I'm probably missing an easier way to parse the string.

  • regular expression for validation not working

    - by Camran
    I have a "description textarea" inside a form where user may enter a description for an item. This is validated with javascript before the form beeing submitted. One of the validation-steps is this: else if (!fld.value.match(desExp)){ And desExp: var desExp = /^\s*(\w[^\w]*){3}.*$/gm; Now my problem, this works fine on all cases except for descriptions where the description BEGINS with a special character of the swedish language (å, ä, ö). This wont work: åäö hello world But this will: hello world åäö Any fixes? Thanks

I want the result here to be a b C after the sorting is done.

  • Accessing and encoding of properties files

    - by NoozNooz42
    I'm used to work with properties files, for example from Ant. Where I can simply reference the property file doing something like that: <property file="webapp_DO_NOT_COMMIT.properties"/> (the file is so named because our DVCS is configured as to never commit files containing "DO_NOT_COMMIT" to prevent committing credentials/passwords/etc.) Here's a very simple .properties file example: passwd=brokencleartextpassword Now I want to put some configuration in another, similar, properties file that I need to access from my Java code. How should I go about it? I also have another related question: is the character encoding of .properties file defined by any spec?

  • C# Console Application - Odd behaviour - char '\a'

    - by KHT
    After extensive debugging of an application, I noticed the console window would hang when searching text for the char '\a'. The goal is to strip out characters from a file. The console window would always hang upon exiting the program, and it would make it to the last statement of main. I removed the '\a' from the switch statement and the console application does not hang anymore. Any idea why? I still need to strip out the char '\a', but cannot get the application to work without hanging. switch (c) { case '\t': //Horizontal Tab case '\v': //Vertical Tab case '\n': //Newline case '\f': //Form feed case '\r': //carriage return case '\b': //Backspace case '\x7f': //delete character case '\x99': //TM Trademark case '\a': //Bell Alert **REMOVED THIS** return true; }

  • How can I parse free text (Twitter tweets) against a large database of values?

    - by user136416
    Hi there Suppose I have a database containing 500,000 records, each representing, say, an animal. What would be the best approach for parsing 140 character tweets to identify matching records by animal name? For instance, in this string... "I went down to the woods to day and couldn't believe my eyes: I saw a bear having a picnic with a squirrel." ... I would like to flag up the words "bear" and "squirrel", as they appear in my database. This strikes me as a problem that has probably been solved many times, but from where I'm sitting it looks prohibitively intensive - iterating over every db record checking for a match in the string is surely a crazy way to do it. Can anyone with a comp sci degree put me out of my misery? I'm working in C# if that makes any difference. Cheers!

  • meaning of (\/?) in regex / is (\w+)([^>]*?) a redundancy?

    - by thomas
    this regular expression should match an html start tag, I think. var results = html.match(/<(\/?)(\w+)([^>]*?)>/); I see it should first capture the <, but then I am confused what this capture (\/?) accomplishes. Am I correct in reasoning that the ([^>]*?)> searches for every character except > = 0 times? If so, why is the (\w+) capture necessary? Doesn't it fall within the purview of [^>]*?

  • ' \r ' vs ' \n ' in C

    - by MCP
    I'm writing a function that basically waits for the user to hit "enter" and then does something. What I've found that works when testing is the below: #include <stdio.h> int main() { int x = getc(stdin); if (x == '\n') { printf("carriage return"); printf("\n"); } else { printf("missed it"); printf("\n"); } } The question I have, and what I tried at first was to do: "if (x == '\r')" but in testing, the program didn't catch me hitting enter. The '\n' seems to correspond to me hitting enter from the console. Can someone explain the difference? Also, to verify, writing it as "if... == "\n"" would mean the character string literal? Ie the user would literally have to enter "\n" from the console, correct? Thanks!

  • C++ STL: Trouble with string iterators

    - by Rosarch
    I'm making a simple command line Hangman game. void Hangman::printStatus() { cout << "Lives remaining: " << livesRemaining << endl; cout << getFormattedAnswer() << endl; } string Hangman::getFormattedAnswer() { return getFormattedAnswerFrom(correctAnswer.begin(), correctAnswer.end()); } string Hangman::getFormattedAnswerFrom(string::const_iterator begin, string::const_iterator end) { return begin == end? "" : displayChar(*begin) + getFormattedAnswerFrom(++begin, end); } char Hangman::displayChar(const char c) { return c; } (Eventually, I'll change this so displayChar() displays a - or a character if the user has guessed it, but for simplicity now I'm just returning everything.) When I build and run this from VS 2010, I get a popup box: Debug Assertion Failed! xstring Line: 78 Expression: string iterator not dereferenceable What am I doing wrong?

  • Ensuring uniqueness on a varchar greater than 255 in MYSQL/InnoDB

    - by Vijay Boyapati
    I have a table which contains HTML entries for news pages. When I initially designed it I used URL as the primary key. I've learned the error of my ways because left-joining is super slow. So I want to redesign the table with an integer (id) primary key, but still keep the rows unique based on the URL. The problem is that I've found URLs longer than 255 characters, and MySQL isn't letting my create a key on the URL. I'm using an InnoDB/UTF8 table. From what I understand it's using multiple bytes per character with a limit of 766 bytes for the key (in InnoDB). I would really love suggestions on an elegant way of keeping the rows unique based on URL, while using an integer primary key. Thanks!

  • Parsing through Arabic / RTL text from left to right

    - by Dan W
    Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

  • Creating Slugs from Titles?

    - by James Jeffery
    I have everything in place to create slugs from titles, but there is one issue. My RegEx replaces spaces with hyphens. But when a user types "Hi     there" (multiple spaces) the slug ends up as "Hi-----there". When really it should be "Hi-there". Should I create the regular expression so that it only replaces a space when there is a character either side? Or is there an easier way to do this?

  • Why does the Win32-API have so many custom types?

    - by sub
    I'm new to the Win32 API and the many new types begin to confuse me. Some functions take 1-2 ints and 3 UINTS as arguments. Why can't they just use ints? What are UINTS? Then, there are those other types: DWORD LPCWSTR LPBOOL Again, I think the "primitive" C types would be enough - why introduce 100 new types? This one was a pain: WCHAR* I had to iterate through it and push_back every character to an std::string as there wasn't another way to convert it to one. Horrible. Why WCHAR? Why reinvent the wheel? They could have just used char* instead, or?

  • Search for string within text column in MySQL

    - by user94154
    I have mysql table that has a column that stores xml as a string. I need to find all tuples where the xml column contains a given string of 6 characters. Nothing else matters--all I need to know is if this 6 character string is there or not. So it probably doesn't matter that the text is formatted as xml. Question: how can I search within mysql? ie SELECT * FROM items WHERE items.xml [contains the text '123456'] Is there a way I can use the LIKE operator to do this? Thanks

  • jquery Troubles with binding to an element by id

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • Reading in multiple words for prolog

    - by prolog123456789
    Im running prolog via poplog on unix and was wondering if there was a way to read in multiple words (such as encase it into a string). For instance, read(X) will only allow X to be 1 term. However, if I encase the user input with "", it will return a list of character codes, is this the correct method as I can not find a way to convert it back to a readable string. I would also like to be able to see if the multiworded string contains a set value (for instance, if it contains "i have been") and am unsure of how i will be able to do this as well.

  • Can I define which characters are allowed to 'break' a word?

    - by zneak
    Hey guys, I'm showing up veeeery long URLs in my Safari extension. Obviously, they can't fit on a single line. Currently, word breaking rules make it so most URLs are on two lines: the first one is rather short and ends with the ? symbol, and the other is ridiculously long and contains all the rest of the GET parameters. I'd like to make it so words also break on the & symbol, without screwing up copy-paste if possible. I've tried to replace every & with &\u00ad (& + the soft hyphen character), but it's kind of weird to see the hyphen after the & when there really isn't any in the URL. I thought there was something in store with CSS3 for that kind of problem, but I can't find it. Any suggestion welcome, as long as it works with Safari.

  • RFC822 Timezone Parsing in Java

    - by Jamen
    Hi, I have a JS date that is being converted by Dojo into RFC822 format. The function call - dojo.date.toRfc3339(jsDate), generates the following date - 2007-02-26T20:15:00+02:00. I have an application that uses a Java date SimpleDateFormat to parse in the dates generated above. I am having problems parsing this date format due to the timezone. I have attempted to use yyyy-mm-DD'T'hh:mm:ssZ This fails as the 'Z' for timezone doesn't expect a ':' character. Does anyone know how I would specify a pattern to handle a RFC822 date with the ':'? Thanks Jamen
