  • PHP regular expression for positive number with 0 or 2 decimal places

    - by Peter
    Hi I am trying to use the following regular expression to check whether a string is a positive number with either zero decimal places, or 2: ^\d+(\.(\d{2}))?$ When I try to match this using preg_match, I get the error: Warning: preg_match(): No ending delimiter '^' found in /Library/WebServer/Documents/lib/forms.php on line 862 What am I doing wrong?

  • intiating lists in the constructor's initialization list

    - by bks
    i just moved from C to C++, and now work with lists. i have a class called "message", and i need to have a class called "line", which should have a list of messages in its properties. as i learned, the object's properties should be initialized in the constructor's initialization list, and i had the "urge" to initialize the messages list in addition to the rest of the properties (some strings and doubles). is that "urge" justified? does the list need to be initialized? thank you in advance

  • grdb not working variables

    - by stupid_idiot
    hi, i know this is kinda retarded but I just can't figure it out. I'm debugging this: xor eax,eax mov ah,[var1] mov al,[var2] call addition stop: jmp stop var1: db 5 var2: db 6 addition: add ah,al ret the numbers that I find on addresses var1 and var2 are 0x0E and 0x07. I know it's not segmented, but that ain't reason for it to do such escapades, because the addition call works just fine. Could you please explain to me where is my mistake? I see the problem, dunno how to fix it yet though. The thing is, for some reason the instruction pointer starts at 0x100 and all the segment registers at 0x1628. To address the instruction the used combination is i guess [cs:ip] (one of the segment registers and the instruction pointer for sure). The offset to var1 is 0x10 (probably because from the begining of the code it's the 0x10th byte in order), i tried to examine the memory and what i got was: 1628:100 8 bytes 1628:108 8 bytes 1628:110 <- wtf? (assume another 8 bytes) 1628:118 ... whatever tricks are there in the memory [cs:var1] points somewhere else than in my code, which is probably where the label .data would usually address ds.... probably.. i don't know what is supposed to be at 1628:10 ok, i found out what caused the assness and wasted me whole fuckin day. the behaviour described above is just correct, the code is fully functional. what i didn't know is that grdb debugger for some reason sets the begining address to 0x100... the sollution is to insert the directive ORG 0x100 on the first line and that's the whole thing. the code was working because instruction pointer has the right address to first instruction and goes one by one, but your assembler doesn't know what effective address will be your program stored at so it pretty much remains relative to first line of the code which means all the variables (if not using label for data section) will remain pointing as if it started at 0x0. which of course wouldn't work with DOS. and grdb apparently emulates some DOS features... sry for the language, thx everyone for effort, hope this will spare someone's time if having the same problem... heheh.. at least now i know the reason why to use .data section :))))

  • How to unit test private methods in BDD / TDD?

    - by robert_d
    I am trying to program according to Behavior Driven Development, which states that no line of code should be written without writing failing unit test first. My question is, how to use BDD with private methods? How can I unit test private methods? Is there better solution than: - making private methods public first and then making them private when I write public method that uses those private methods; or - in C# making all private methods internal and using InternalsVisibleTo attribute.

  • BackgroundWorker Thread in IIS7 - FAIL!

    - by Darren Oster
    Just wondering if anyone has had any trouble using a BackgroundWorker Thread in a site running under IIS 7 in Integrated Pipeline mode? I am trying to use such a beast to update the database schema (admin function, obviously), and it works perfectly in Cassini, but when I deploy to IIS 7, the thread gets about one line of code in and silently ends. Is there a way to tell why a thread ended? Thanks in advance.

  • How to properly encode "[" and "]" in queries using Apache HttpClient?

    - by Jason Nichols
    I've got a GET method that looks like the following: GetMethod method = new GetMethod("http://host/path/?key=[\"item\",\"item\"]"); Such a path works just fine when typed directly into a browser, but the above line when run causes an IllegalArgumentException : Invalid URI. I've looked at using the URIUtils class, but without success. Is there a way to automatically encode this (or to add a query string onto the URL without causing HttpClient to barf?).

  • ajax cross-domain requests

    - by yoda
    Hi, Since Ajax requests are limited for security reasons, there's not much to it, just follow the rules eh .. but I've crossed with this : https://developer.mozilla.org/en/Same_origin_policy_for_JavaScript It's written that you can "bypass" those rules, in case you're working with subdomains of the same domain, with the following javascript line : document.domain = "company.com"; I haven't tried it yet, since I don't know if this only works (perfectly works) with any other browser, or at least the major ones. Is it possible? Thanks.

  • Why is the order of evaluation for function parameters undefined in c++?

    - by kunj2aan
    The standard doesn't specify the order of evaluation of arguments with this line: The order of evaluation of arguments is unspecified. What does Better code can be generated in the absence of restrictions on expression evaluation order imply? What is the drawback in asking all the compilers to evaluate the function arguments Left to Right for example? What kinds of optimizations do compilers perform because of this undefined spec?

  • c++, object life-time of anonymous (unnamed) variables

    - by Joe Steeve
    In the following code, the object constructed in the last line of 'main()', seems to be destroyed before the end of the expression. The destructor is called before the '<<' is executed. Is this how it is supposed to be? #include <string> #include <sstream> #include <iostream> using std::string; using std::ostringstream; using std::cout; class A : public ostringstream { public: A () {} virtual ~A () { string s; s = str(); cout << "from A: " << s << std::endl; } }; int main () { string s = "Hello"; A os; os << s; cout << os.str() << std::endl; A() << "checking this"; } This is the output: Hello from A: 0x80495f7 from A: Hello This is the gdb log: (gdb) b os.cxx : 18 Breakpoint 1 at 0x80492b1: file os.cxx, line 18.

  • JSon/Jquery request with a setTimeout always returns a "null" result? (for Twitter Search API)

    - by supermogx
    I make a call to the twitter API. 100 posts are retreived + a properties that tells me what the next page to call is. So I wait 5 sec. and call that next page, but the JSon results in the callback function is always null the second time... I think it's probably a JQuery problem... Here's a complete sample HTML code : <html> <head> <script type="text/javascript" src="./jquery-1.4.2.min.js"></script> <script> function test() { var rqUrl = "http://search.twitter.com/search.json?q=%23apple+OR+%23ipad&rpp=100&callback=?" callTwitterSearchApi(rqUrl); } function callTwitterSearchApi(tiwtterRequestUrl) { debug("request to twitter : " + tiwtterRequestUrl); // *** FIRST CALL WORKS GREAT... *** $.getJSON(tiwtterRequestUrl, callTwitterSearchApi_callback); } function callTwitterSearchApi_callback(jsonPostsResults) { debug("callback"); if (jsonPostsResults == null) { debug("Why is jsonPostsResults null? If I copy paste the request inside a browser, I get something =("); return; } if (jsonPostsResults.error != undefined && jsonPostsResults.error != "") { debug("twitter api error"); } var posts = new Array(); $(jsonPostsResults.results).each(function() { posts.push(this); }); debug("Number of posts : " + posts.length); if (jsonPostsResults.next_page != undefined && jsonPostsResults.next_page.trim() != "") { debug("calling next request in 5 sec..."); // *** WHEN COMMING BACK FROM THAT LINE, JSON RESULTS == NULL?! **** setTimeout("callTwitterSearchApi(\"http://search.twitter.com/search.json" + jsonPostsResults.next_page + "\")", 5000); } } function debug(message) { document.getElementById('debug').innerHTML = message + "\n" + document.getElementById('debug').innerHTML; } </script> </head> <body> <input type="button" onclick="test();" value="test" /><br /> <textarea id="debug" cols="80" rows="20"></textarea> </body> </html> at line 18, at the second callback (back from the setTimeout), the parameter "jsonPostsResults" is always returned as null... I have no idea why. If I copy paste that 2nd request in a browser, it returns 100 results. Anybody had a problem like that with the Ajax JQuery functions when calling it with a setTimeout?

  • Starting python debugger automatically on error

    - by jeremy
    This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.

    Hello all, I have this line of code which rounds my numbers to 2 decimal places. But the thing is I get numbers like this. 10.8, 2.4 etc. These are not my idea of 2 decimal places so how I can improve this: Math.round(price*Math.pow(10,2))/Math.pow(10,2); I want numbers like 10.80, 2.40 etc. Use of JQuery is fine with me. Thanks for any help.

  • How to concatenate all commit messages from subversion into one text file with no metadata?

    - by user144182
    I would like to take all the commit messages in my subversion log and just concatenate them into one text file. Each commit message has this format: - r1 message - r1 message - r1 message What I would like is something like: - r1 message - r1 message - r2 message - r2 message - r3 message [...] - r1000 message Update I thought the above was clear, but what I don't want in the log is this type of info: r2130 | user| 2010-03-19 10:36:13 -0400 (Fri, 19 Mar 2010) | 1 line No meta data, I simply want the commit messages.
