  • [java] how to parse XML document?

    - by user32167
    I have xml document in variable (not in file). How can i get data storaged in that? I don't have any additional file with that, i have it 'inside' my sourcecode. When i use DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.parse(XML); (XML is my xml variable), i get an error java.io.FileNotFoundException: C:\netbeans\app-s7013\<network ip_addr="10.0.0.0\8" save_ip="true"> File not found.

  • perl script grabbing environment vars from "someplace else"

    - by Michael Wilson
    On a Solaris box in a "mysterious production system" I'm running a perl script that references an environment variable. No big deal. The contents of that variable from the shell both pre and post execution are what I expect. However, when reported by the script, it appears as though it's running in some other sub-shell which is clobbering my vars with different values for the duration of the script. Unfortunately I really can't paste the code. I'm trying to get an atomic case, but I'm at my wit's end here. Thoughts?

  • Enabling Squid delay pool eats up the entire memory

    - by Supratik
    I am using "squid-3.1.8-1.el5" in my CentOS 5 32 bit system. In normal condition Squid uses 85m - 90m, but when I enable the delay pool parameters the memory usage suddenly rise up 2GB. The memory keeps on increasing until the system is out of resource. The following are my delay pool settings: delay_pools 1 delay_class 1 1 delay_access 1 allow all delay_parameters 1 192000/192000 Is there anything I am missing here or is it a bug with Squid ?

  • Achieving C# "readonly" behavior in C++

    - by Tommy Fisk
    Hi guys, this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as "readonly" allows a programmer to assign some value to that variable exactly once. Further attempts to modify the variable will result in an error. What I am after: I want to make sure that any and all single-ton classes I define can be predictably instantiated exactly once in my program (more details at the bottom). My approach to realizing my goal is to use extern to declare a global reference to the single-ton (which I will later instantiate at a time I choose. What I have sort of looks like this, namespace Global { extern Singleton& mainInstance; // not defined yet, but it will be later! } int main() { // now that the program has started, go ahead and create the singleton object Singleton& Global::mainInstance = Singleton::GetInstance(); // invalid use of qualified name Global::mainInstance = Singleton::GetInstance(); // doesn't work either :( } class Singleton { /* Some details ommited */ public: Singleton& GetInstance() { static Singleton instance; // exists once for the whole program return instance; } } However this does not really work, and I don't know where to go from here. Some details about what I'm up against: I'm concerned about threading as I am working on code that will deal with game logic while communicating with several third-party processes and other processes I will create. Eventually I would have to implement some kind of synchronization so multiple threads could access the information in the Singleton class without worry. Because I don't know what kinds of optimizations I might like to do, or exactly what threading entails (never done a real project using it), I was thinking that being able to predictably control when Singletons were instantiated would be a Good Thing. Imagine if Process A creates Process B, where B contains several Singletons distributed against multiple files and/or libraries. It could be a real nightmare if I can not reliably ensure the order these singleton objects are instantiated (because they could depend on each other, and calling methods on a NULL object is generally a Bad Thing). If I were in C# I would just use the readonly keyword, but is there any way I can implement this (compiler supported) behavior in C++? Is this even a good idea? Thanks for any feedback.

  • Converting a PHP array to class variables.

    - by animuson
    Simple question, how do I convert an associative array to variables in a class? I know there is casting to do an (object) $myarray or whatever it is, but that will create a new stdClass and doesn't help me much. Are there any easy one or two line methods to make each $key => $value pair in my array into a $key = $value variable for my class? I don't find it very logical to use a foreach loop for this, I'd be better off just converting it to a stdClass and storing that in a variable, wouldn't I? class MyClass { var $myvar; // I want variables like this, so they can be references as $this->myvar function __construct($myarray) { // a function to put my array into variables } }

  • What is a good standard for code width?

    - by BillyONeal
    Hello everyone :) I've heard in several places that it's bad to have code that is too wide onscreen. For example: for (std::vector<EnumServiceInformation>::const_iterator currentService = services.begin(); currentService != services.end(); currentService++) However, I've heard many arguments for 80 character wide limits. I'm assuming this 80 character limit comes from the traditional command prompt, which is typically 80 characters wide. However -- most of us are working on something much better than a typical command prompt, and I feel that using an 80 character limit encourages use of variable names that are far too short and do not describe what the variable is used for. What is a reasonable limit for a new project with no existing coding width standard?

  • Make Chrome browser prefer DNS over searching

    - by dronus
    Is it possible to let the Chrome browser prefer all DNS resolvable URLs over a search? Everytime I use a local name not matching a usual domain scheme, I got search results for it. I first thought that no nonsense DNS lookup is made if the URL seems to be a search keyword, however Chrome always detect this condition and asks me if I like to go to my domain instead. So the DNS lookup is made anyway.

  • Will this make the object thread-safe?

    - by sharptooth
    I have a native Visual C++ COM object and I need to make it completely thread-safe to be able to legally mark it as "free-threaded" in th system registry. Specifically I need to make sure that no more than one thread ever accesses any member variable of the object simultaneously. The catch is I'm almost sure that no sane consumer of my COM object will ever try to simultaneously use the object from more than one thread. So I want the solution as simple as possible as long as it meets the requirement above. Here's what I came up with. I add a mutex or critical section as a member variable of the object. Every COM-exposed method will acquire the mutex/section at the beginning and release before returning control. I understand that this solution doesn't provide fine-grained access and this might slow execution down, but since I suppose simultaneous access will not really occur I don't care of this. Will this solution suffice? Is there a simpler solution?

  • function to org-sort by three (3) criteria: due date / priority / title

    - by lawlist
    Is anyone aware of an org-sort function / modification that can refile / organize a group of TODO so that it sorts them by three (3) criteria: first sort by due date, second sort by priority, and third sort by by title of the task? EDIT: If anyone can please help me to modify this so that undated TODO are sorted last, that would be greatly appreciated -- at the present time, undated TODO are not being sorted: ;; multiple sort (defun org-sort-multi (&rest sort-types) "Multiple sorts on a certain level of an outline tree, or plain list items. SORT-TYPES is a list where each entry is either a character or a cons pair (BOOL . CHAR), where BOOL is whether or not to sort case-sensitively, and CHAR is one of the characters defined in `org-sort-entries-or-items'. Entries are applied in back to front order. Example: To sort first by TODO status, then by priority, then by date, then alphabetically (case-sensitive) use the following call: (org-sort-multi '(?d ?p ?t (t . ?a)))" (interactive) (dolist (x (nreverse sort-types)) (when (char-valid-p x) (setq x (cons nil x))) (condition-case nil (org-sort-entries (car x) (cdr x)) (error nil)))) ;; sort current level (defun lawlist-sort (&rest sort-types) "Sort the current org level.

  • Connection: Keep-Alive and PHP sessions not working

    - by user366667
    We have a VB application that needs to run an specific flow on a PHP page. This application was correctly catching the PHPSESSID cookie and using it for all subsequent requests. However, PHP wasn't able to restore any changes made on $_SESSION variable. The variable was changed, saved, and on the next request it was restored as an empty array. We found out that changing the Connection header from "Keep-Alive" to "Close" fixed the issue. I couldn't find anything on the web saying that PHP sessions shouldn't be restored under Keep-Alive connections. Does anyone know why this was happening? PS: We didn't find anything weird or different on Apache, ModSecurity or PHP configuration settings.

  • Getting access to a custom Master page from a user control

    - by Bernard
    Hi We have created a Master page that inherits off the asp.net Master class. We have also got ui controls that inherit off the standard asp.net ui control class. Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use. However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?

  • Calling some functions before main in C

    - by minjang
    I'd like to do some stuffs before main function. I have multiple source files. In each file, there is some work that needs to be done before main. It was no problem in C++, but problematic with C. In C++, this can be done by two ways: Exploiting a constructor of a global class/struct. Calling a function to a global variable For example, static const int __register_dummy_ = __AddRegisterMetaInfo(...); However, in C, either ways is impossible. Obviously, there is no constructor. So, the first option is inherently impossible. I thought that the second option would be possible, but not compiled in C (I tested only with Visual C++. It gives C2099.). C only allows a constant to a non-automatic variable. Is there any way to call some functions before main?

  • Multiple mod rewrites in .htaccess

    - by Bob
    I want the following rules but I don't seem to get the right setup. <domain>/training-courses/ both with or without the slash at the end it should go to: <domain>/?index.php?page=training-courses and for each variable extra after this I want it to behave like this: <domain>/training-courses/success/another-value/and-yet-another/ to <domain>/?index.php?page=training-courses&val1=success&val2=another-value&val3=and-yet-another-value If it's not possible to have the option for unlimited leading variables, i'd like to have at least 2 variables after the page variable Is this possible? and how do I get this sorted out? I have this so far: RewriteEngine On RewriteRule ^test/([^/]*)/$ /test/index.php?pagina=$1&val1=$2 RewriteRule ^test/([^/]*)$ /test/index.php?pagina=$1&val1=$2 RewriteRule ^test/([^/]*)/([^/]*)/$ /test/index.php?pagina=$1&val1=$2 RewriteRule ^test/([^/]*)/([^/]*)$ /test/index.php?pagina=$1&val1=$2 RewriteRule ^test/([^/]*)/([^/]*)/([^/]*)/$ /test/index.php?pagina=$1&val1=$2&val2=$3 RewriteRule ^test/([^/]*)/([^/]*)/([^/]*)$ /test/index.php?pagina=$1&val1=$2&val2=$3

  • Running JBoss 4.2.3 and JBoss 5.1 on the same server

    - by user115212
    I want to run JBoss 4.2.3 and JBoss 5.1 on the same server, but not simultaneously. I just need to be able to switch back and forth between the two for testing, so I don't need to change ports or anything like that. My problem is the JBOSS_HOME environment variable. When I set up a /soft/JBoss-4.2.3.GA directory and a /soft/JBoss-5.1.0.GA directory I can run the respective bin run.sh commands, however, both try to use the $JBOSS_HOME and $PATH environment variables which are set to the first installation (JBoss-4.2.3). So, how can I set separate environment variables? Or tell my new JBoss 5.1 installation to use another environment variable for JBOSS_HOME? How would I go about getting these two running together? Thanks!

  • Any chances to imitate times() Ruby method in C#?

    - by Alexander Prokofyev
    Every time I need to do something N times inside an algorithm using C# I write this code for (int i = 0; i < N; i++) { ... } Studying Ruby I have learned about method times() which can be used with the same semantics like this N.times do ... end Code fragment in C# looks more complex and we should declare useless variable i. I tried to write extension method which returns IEnumerable, but I am not satisfied with the result because again I have to declare a cycle variable i. public static class IntExtender { public static IEnumerable Times(this int times) { for (int i = 0; i < times; i++) yield return true; } } ... foreach (var i in 5.Times()) { ... } Is it possible using some new C# 3.0 language features to make N times cycle more elegant?

    This is my Working Code DriftMul:=99; WriteProcessMemory(HandleWindow, ptr($4E709C), @DriftMul, 2, Write); I want to Convert it without using a variable but it wont work Below is just an Example of what i want to do. WriteProcessMemory(HandleWindow, ptr($4E709C), ptr(99), 2, Write); Does anyone know a way to make this work with using a variable??? I am able to program in a few languages and every language i use their is a way to to do this. The reason i want to do this is because i am gonna be making a big program that does alot of writing of different values and it will save me around 300+ lines. Below is an Example in c++ i was using.

  • Hiding result sets from multiple selects in a stored procedure

    - by Josh Young
    I have a stored procedure that retrieves SQL queries as text and executes the statements using sp_executesql. Each of the dynamic queries is a count query in that it only returns the number of records found (select COUNT(id) from...). I am looping through a set of SQL queries stored as text and building a table variable out of the results. At the end, I am selecting all the results from the table variable as the result set that I want returned from the stored procedure. However, when I execute the stored procedure, I am naturally getting multiple result sets (one for each of the dynamic queries and one for the final select.) Is there any way I can suppress the results of a select statement executed through sp_executesql? I have found answers that reference storing the results in a temp table, but I don't have control of the query text that I am running so I can't change it to select into anything. Please help. Thank you for your time.

  • How to name variables which are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

  • While Loop in TSQL with Sum totals

    I have the following TSQL Statement, I am trying to figure out how I can keep getting the results (100 rows at a time), store them in a variable (as I will have to add the totals after each select) and continue to select in a while loop until no more records are found and then return the variable totals to the calling function. SELECT [OrderUser].OrderUserId, ISNULL(SUM(total.FileSize), 0), ISNULL(SUM(total.CompressedFileSize), 0) FROM ( SELECT DISTINCT TOP(100) ProductSize.OrderUserId, ProductSize.FileInfoId, CAST(ProductSize.FileSize AS BIGINT) AS FileSize, CAST(ProductSize.CompressedFileSize AS BIGINT) AS CompressedFileSize FROM ProductSize WITH (NOLOCK) INNER JOIN [Version] ON ProductSize.VersionId = [Version].VersionId ) AS total RIGHT OUTER JOIN [OrderUser] WITH (NOLOCK) ON total.OrderUserId = [OrderUser].OrderUserId WHERE NOT ([OrderUser].isCustomer = 1 AND [OrderUser].isEndOrderUser = 0 OR [OrderUser].isLocation = 1) AND [OrderUser].OrderUserId = 1 GROUP BY [OrderUser].OrderUserId

  • Convert PHP array into Key => Value Array

    Total PHP Noob and I couldn't find an answer to this specific problem. Hope someone can help! $myvar is an array that looks like this: Array ( [aid] = Array ( [0] = 2 [1] = 1 ) [oid] = Array( [0] = 2 [1] = 1 ) ) And I need to set a new variable (called $attributes) to something that looks like this: $attributes = array($myvar['aid'][0] => $myvar['oid'][0], $myvar['aid'][1] => $myvar['oid'][1], etc...); And, of course, $myvar may contain many more items... How do I iterate through $myvar and build the $attributes variable?

  • PHP export to text file - Only saving first line.

    - by wertz8090
    I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

  • Displaying objects based on if a user is logged in or not

    - by MaxMackie
    I'm learning about PHP sessions for user authentication on my website. I know how to restrict the viewing of a complete page using sessions (simply check if the 'uid' session variable is set and if it is, show content, if not redirect to an error). However I'm trying to figure out the best way to selectively show and hide different objects (div, text, images) based on if a user is logged in or not. Is it as simple as checking for the 'uid' session variable and displaying based on if it set or not? Is there a more efficient way of doing this id there are a lot of conditional elements on a page?
