  • PHP memcache - check if any server is available in pool?

    - by Industrial
    Hi everyone, I have the following code: $cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50); $cluster['local2'] = array('host' => '192.168.1.2', 'port' => '11211', 'weight' => 50); $this->memcache = new Memcache; foreach ($this->cluster() as $cluster) { $this->memcache->addServer($cluster['host'], $cluster['port'], $this->persistent, $cluster['weight'], 10, 10, TRUE , 'failure' ); } I would like to make a function that checks if any of my servers in my memcache Pool is available. How could this be done?

  • MonoTouch's Soft Debugger don't connect to App on iPhone - why?

    - by smokinharp
    Hi everyone, I'm quite new on MonoTouch, so please forgive me my question in doubt... ;-) I need help with the soft-debugger, because it's not connecting to the App on the device. While with iPhone Simulator everything is working as expected, the following happens when I start debugging against my device: The is uploaded and installed to the device. MonoDevelop comes up with a window saying the following: "Waiting for debugger to connect on 127.0.0.1:10000..." Please start the application on the device" When starting the app on the device, the device vibrates indicating that the debugger is not connected.... In the settings of my App on the iPhone I have set the IP-Adress to my Mac's IP. My iPhone is connected via WIFI to my network. I can ping my Mac from my iPhone and vice versa. In several screenshots where the debugger was obviously working I saw that the debugger came up with the Mac's IP address and not the 127.0.0.1.... Do I have to configure my IP-address somewhere in MonoDevelop? BTW: I'm using the latest version of MonoDevelop - it's 2.4.1 I have tried anything.... re-installing MonoDevelop, cleaning up the project several times, setting up a new project.... nothing... Please, please help....

  • CSS to Make 2 Column Content Areas

    - by Joe Majewski
    I'm trying to stray away from using tables to form the layout of my content, and I can think of two alternatives that I'd like to better learn: (1) styling list items to be side-by-side, and (2) using div blocks that float onto the same line. Both of these would have their own uses for what I'm working on. I'm already using div tags to form the entire layout of my three-column template, but what I need to do now is a bit different. In case it helps, my project can be found here. In short, here's my question; how would I style a div so that the width of it is 50% of the width of the area it occupies, rather than 50% of the width of the page? As for my other question, what would be the best approach to styling list items so that they are side-by-side? I'm working on a registration script now, and instead of using a table with "Username" on the left and the input text on the right, I can use two list items. It's late and I've been working on this project of mine for about 8 hours straight now, so I apologize if I'm asking anything confusing. Feel free to ask me any questions about what I'm trying to do. Thanks, friends. :)

  • __declspec(dllimport) causes compiler crash on MSVC 2010

    - by Zero
    In a *.cpp file, trying to use a third party lib: #define DLL_IMPORT #include <thirdParty.h> // Third party header has code like: // #ifdef DLL_IMPORT // #define DLL_DECL __declspec(dllimport) // fatal error C1001: An internal error has occurred in the compiler. Alternative: #define NO_DLL #include <thirdParty.h> // Third party header has code like: // #elif defined(NO_DLL) // #define DLL_DECL // Compiles fine, but linker errors as can't find DLL functions // I can reproduce results by remove macros and #define all together and manually editing the third party files to have __declspec(dllimport) or not Has anyone come across anything similar, or can hint at the cause? (which is created using CMake). Above is actual example of 2 line *.cpp that crashes so it's narrowed down to something in the #include. The following also work fine: Compile the examples provided by the third party (they provide a *.sln) that use dllimport/export so it doesn't appear to be the fault of the library Compile the third party lib as part of the production project (so dllexport works fine) I've trawled the project settings pages of the two projects to try and spot differences, but have come up blank. Of course, it's possible I'm missing something as those settings pages are not the easiest to navigate. I'll get access to VS2008 in a day or so, so can compare with that. The third party library is MySql++.

  • Which HRESULT literal constant will fail the SUCCEEDED() macro?

    - by Hamish Grubijan
    Definition of SUCCEEDED(): #define SUCCEEDED(hr) (((HRESULT)(hr)) >= 0) Background: When an Ok button is clicked on a dialog, I need to return an HRESULT value hr such that SUCCEEDED(hr) is true. If Cancel button is clicked, I need to return a negative value. I could have used bools, but that would break the existing pattern (usually the hr values come from depths of system dlls). So, I know I can return S_OK on Ok, but what do I return on Cancel? I could just return (HRESULT)-1;, but there must be a better way - some HRESULT literal constant which has negative value and represents a generic failure. S_FALSE is not it, for it's value is defined as 1L. Please help me find the right constant.

  • Dynamic External Program in debug tab vs2008

    - by Justin Holbrook
    I am playing with NServiceBus using the generic host; specifically I'm working on having 2 different configurations, a debug configuration that logs to the console and a release version that logs to metabase (I'm using VS2008). I had just made some code changes (commented out a logging statement), but it was still showing in the log when I ran my solution. I eventually figured out that I had switched configuration to release, made my change, then built. I think the change isn’t being picked up because in the debug tab of my project properties I have the following (abbreviated) path to the generic host: C:...\Inventory\bin\Debug\NServiceBus.Host.exe Notice it specifically points to the debug directory. So basically even though I’m in release config it’s firing up the host in the debug directory which I think is then using the dll's in the debug directory (which is why my changes didn't get picked up). I tried to come up with a workaround, but have been unsuccessful. VS Macros (like $(Configuration)) and relative pathing are not allowed here. http://connect.microsoft.com/VisualStudio/feedback/details/422223/relative-path-not-allowed-in-c-project-debug-properties-window Any ideas? I hope this doesn’t require a custom build task.

  • [C++] Boost test: catch user defined exceptions

    - by user231536
    If I have user defined exceptions in my code, I can't get Boost test to consider them as failures. For example, BOOST_AUTO_TEST_CASE_EXPECTED_FAILURES(MyTest,1) BOOST_AUTO_TEST_CASE(MyTest) { // code which throws user defined exception, not derived from std::exception. } I get a generic message: Caught exception: .... unknown location(0):.... It does not recognize this error as a failure since it is not a std::exception. So it does not honor the expected_failures clause. How do I enforce that the piece of code should always throw an exception? THis seems to be a useful thing to want. In case future code changes cause the code to pass and the exception is not thrown, I want to know that.

  • How to implement a search page which shows results on the same page?

    - by Andrew
    I'm using ASP.NET MVC 2 for the first time on a project at work and am feeling like a bit of a noob. I have a page with a customer search control/partial view. The control is a textbox and a button. You enter a customer id into the textbox and hit search. The page then "refreshes" and shows the customer details on the same page. In other words, the customer details appear below the customer search control. This is so that if the customer isn't the right one, the user can search again without hitting back in the browser. Or, perhaps they mistyped the customer id and need to try again. I want the URL to look like this: /Customer/Search/1 Obviously, this follows the default route in the project. Now, if I type the URL above directly into my browser, it works fine. However, when I then use the search control on that page to search for say customer 2, the page refreshes with the correct customer details but the URL does not change! It stays as /Customer/Search/1 When I want it to be /Customer/Search/2 How can I get it to change to the correct URL? I am only using the default route in Global.asax. My Search method looks like this: <AcceptVerbs(HttpVerbs.Get)> _ Function Search(ByVal id As String) As ActionResult Dim customer As Customer = New CustomerRepository().GetById(id) Return View("SearchResult", customer) End Function

  • Flattening out a lib directory using jarjar

    - by voodoogiant
    I'm trying to flatten out the lib directory of a project using jarjar, where it will produce a jar file with my main code and all my required libraries inside of it. I can get the project code into the jar, but I need to find a way to get every jar in the './lib/' directory extracted to the base directory of the final output jar. I don't want it flattened in the sense that I still want the package hiearchy preserved. I could manually list every jar file using zipfileset, but I was hoping to do it dynamically. I would also like to include any *.so files flattened into the base directory of the output jar so I can extract them into a temp dir easily without having to search through the jar. For example my lib directory... ./lib/library1.jar ./lib/library2.jar ./lib/foo/library3.jar ./lib/foo/bar.so would look like this when cracked open in the output jar file... /..library1_package_hierarchy../lib1.class /..library1_package_heirarchy../lib2.class ... (and so on) /..library2_package_hierarchy../lib1.class /..library2_package_heirarchy../lib2.class ... (and so on) /..library3_package_hierarchy../lib1.class <-- foo gone /..library3_package_heirarchy../lib2.class <-- foo gone /bar.so <-- foo gone

  • Trying to understand the Zend_Auth OpenId

    - by Will Olbrys
    I'm using a slightly modified version of the Zend_Auth_OpenId classes to get openid logins from google apps. The results are very positive, as I seem to be getting successful results from Google. I cannot get successful results passed to Zend_Auth, though. For example, Zend_Auth_Adapter_OpenId on line 241: if (!$consumer->login($id, $this->_returnTo, $this->_root, $this->_extensions, $this->_response)) { return new Zend_Auth_Result( Zend_Auth_Result::FAILURE, $id, array("Authentication failed", $consumer->getError())); } The consumer calls login() which in turn calls the private method _checkId() in Zend_OpenId_Consumer. _checkId() always ends in redirecting to the openid server. How is this ever supposed to return a valid Zend_Auth_Result object? I'm pretty close to giving up and trying to implement another OpenId library, but I'm so close to just making this work. I must be missing something so obvious! Maybe I don't understand how openid works exactly, but if someone could help me understand I would really appreciate it.

  • Compiling 32-bit Program on VS 2008

    - by gordonwd
    I've been developing on VC++ 2003 on an XP PC but am now on Windows 7 and bought a cheap legal copy of VS 2008 to continue work on the same project. My product has to continue to run on customers' XP systems, so I'm strictly interested in a 32-bit executable. The first issue I ran into was the PRJ0003 error "spawning cl.exe". I had to add the path to this file to the VC++ Directories settings (it appears in both a bin\amd64 and bin\x86_amd64 directory, but I don't think it matters output-wise which I use?). The issue I now have (not counting a tedious cleanup to convert strcpy to strcpy_s, etc.) is that I'm not clear on whether I'm generating a 32-bit or 64-bit exe out of this. My project properties are set to a target of "Win32", so I assume that all is well. Is this correct? I have read some discussions about this, but it's never quite clear if they are talking about whether the compiler itself is running x64 vs. x86, or whether the compiled code is x64 vs. x86, and how this is differentiated. So am I doing the right thing to generate a 32-bit, Win32, x-86 program?

  • Parse and Break: why break cannot be used for getting out of "any" or "some" rule ?

    - by Rebol Tutorial
    Let say I have to parse a hierarchical set of tags <tag> <subtag1 attr1=value1 attr2=value2> <subtag1 attr1=value1 attr2=value2> <subtag1 attr1=value1 attr2=value2> </tag> Why can't I use break inside some or any to get out of a level hierarchy ? This would allow to do that kind of parsing instead of having a headache to do so ? I'm asking this because I read here http://www.codeconscious.com/rebol/parse-tutorial.html it would create an infinite loop This case produces an infinite loop. Because the BREAK is within a sub-rule of the rule that SOME is processing. The BREAK does not affect success/failure status or the input pointer - it just exits a rule early: rule-to-break: [(print "Break") break] == [(print "Break") break] parse "X" [some [rule-to-break] "X"] Break *Break* ... Break *Break*(escape)

  • What's the best way to use hamcrest-AS3 to test for membership in an IList?

    - by Chris R
    I'm using Flex 3.3, with hamcrest-as3 used to test for item membership in a list as part of my unit tests: var myList: IList = new ArrayCollection(['a', 'b', 'c']).list; assertThat(myList, hasItems('a', 'b', 'c')); The problem is that apparently the IList class doesn't support for each iteration; for example, with the above list, this will not trace anything: for each (var i: * in myList) { trace (i); } However, tracing either an Array or an ArrayCollection containing the same data will work just fine. What I want to do is (without having to tear apart my existing IList-based interface) be able to treat an IList like an Array or an ArrayCollection for the purposes of testing, because that's what hamcrest does: override public function matches(collection:Object):Boolean { for each (var item:Object in collection) { if (_elementMatcher.matches(item)) { return true; } } return false; } Is this simply doomed to failure? As a side note, why would the IList interface not be amenable to iteration this way? That just seems wrong.

  • Why Is Java Missing Access Specifiers?

    - by Tom Tresansky
    Does anyone understand why Java is missing: An access specifier which allows access by the class and all subclasses, but NOT by other classes in the same package? (Protected-minus) An access specifier which allows access by the class, all classes in the same package, AND all classes in any sub-package? (Default-plus) An access specifier which adds classes in sub-packages to the entities currently allowed access by protected? (Protected-plus) I wish I had more choices than protected and default. In particular, I'm interested in the Protected-plus option. Say I want to use a Builder/Factory patterned class to produce an object with many links to other objects. The constructors on the objects are all default, because I want to force you to use the factory class to produce instances, in order to make sure the linking is done correctly. I want to group the factories in a sub-package to keep them all together and distinct from the objects they are instantiating---this just seems like a cleaner package structure to me. No can do, currently. I have to put the builders in the same package as the objects they are constructing, in order to gain the access to defaults. But separating project.area.objects from project.area.objects.builders would be so nice. So why is Java lacking these options? And, is there anyway to fake it?

  • PHP callback function not being called

    - by Industrial
    Hi everyone, I've got the following code: function _callback_memcache_failure($host, $port) { print "memcache '$host:$port' failed"; } $this->memcache = new Memcache; $this->memcache->addServer('192.168.1.35', '11211', 0, 50, 10, TRUE, _callback_memcache_failure('192.168.1.35','11211')); The server is online and running (verified!), but the Failure callback function is being called at each connection. Why is that? Reference: PHP documentation: Memcache::addServer - failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server .

    okay I am totally stuck. I have been getting some help off and on throughout this project and am anxious to get this problem solved so I can continue on with the rest of this project. I have a gridview that is set to save to a file, and has the option to import into excel. I keep getting an error of this: Invalid cast exception was unhandled. At least one element in the source array could not be cast down to the destination array type. Can anyone tell me in layman easy to understand what this error is speaking of?

  • Mercurial "server"

    - by user85116
    I've been using mercurial for a little while, but mainly for my own usage. Now though, I have a project I'm working on where two of us are building the same project, and we will probably be modifiying each other's files. I would like to setup a mercurial repo on a server, make that repo the "server", so my changes and the other editor's changes both push to that server (so basically the subversion / cvs model); I like mercurial though, and don't want to switch to something like subversion. Here in my own network, everything is done on linux, and my "server" has openssh installed. So pushing my changes (I work on multiple computers) from one computer to the server is just a matter of "hg push"; the protocol used is ssh for transfering the changes. The problem is that I use linux, the server will be windows (so no openssh, right?) and the other editor will be using windows too. As far as I know, the best way of working in mercurial in these types of setups is for the repo to pull changes from the source, rather then the source pushing to the "server". I'm behind several firewall's (not entirely my network) and my computer won't be visible from the server, and I'm assuming the other editor will be behind a firewall too (so we can't just start up the local mercurial http server and get the "server" computer to pull from that). What's the best way for both editors to get our changes to the server repo? (I should add that the server is a server on the internet, so just as visible as something like google.com. It's a hosted windows server, but I would probably have permission to install software if needed for this)

  • Should I be worried if I don't get any internships by 3rd year's end?

    - by karamba
    I am in some mediocre college in some corner of India. Am about to complete 3rd year C.S. in a month and a half. I have no idea how to go about "finding an internship" as everyone seems to put it. Looking at online advice, I find that a primary way is to "use your contacts". I am sad to say that I don't have many friends(those I have, I am trying to get help from them for all it's worth), and my family can't help me as they have no idea about the software industry. My college has no official facility for aiding students in this, and the few faculty members who had contacts in "whatever" part of the industry have favoured some students that they have personally come to know. (Though I hear that the "internships" they got involve them stocking equipment in some small companies.... still it's something?) I'm getting nervous. I am considering just spending the coming summer refining my skills in C++ and begin learning MySQL and C#, both of which I have zero experience in. Maybe work on my own project... like a library management system. Relative to those in my college, I think I am among the best programmers there, but that isn't saying much as a lot of students can barely write basic code. I have experience in teaching myself C++, and DirectX9 having created a Tetris clone, some basic 3D apps (bouncing balls), and a basic console-based, text-file-database-using library management system (which I plan to improve this summer). Is it alright if I spend my summer so? Will I be able to get a job later on? I know I have to improve my social skills to get anywhere in life, and I will try, but say I am stuck like this till 4th year's end... will such self studying, online learning help me in landing a decent job? Perhaps after I have learned a bit more, joining some open source project?

  • Java: I've created a list of word objects to include the name and the frequency, but having trouble

    - by adam08
    Hi Everyone, I'm working on a project which has a dictionary of words and I'm extracting them and adding them to an ArrayList as word objects. I have a class called Word as below. What I'm wondering is how do I access these word objects to update the frequency? As part of this project, I need to only have one unique word, and increase the frequency of that word by the number of occurrences in the dictionary. Word(String word) { this.word = word; this.freq = 0; } public String getWord() { return word; } public int getFreq() { return freq; } public void setFreq() { freq = freq + 1; } This is how I am adding the word objects to the ArrayList...I think it's ok? String pattern = "[^a-zA-Z\\s]"; String strippedString = line.replaceAll(pattern, ""); line = strippedString.toLowerCase(); StringTokenizer st = new StringTokenizer(line); while (st.hasMoreTokens()) { String newWord = st.nextToken(); word.add(new Word(newWord)); count++; }

  • NHibernate lazy properties behavior?

    - by GeReV
    I've been trying to get NHibernate into development for a project I'm working on at my workplace. Since I have to put a strong emphasis on performance, I've been running a proof-of-concept stress test on an existing project's table with thousands of records, all of which contain a large text column. However, when selecting a collection of these records, the select statement takes a relatively long time to execute; apparently due to the aforementioned column. The first solution that comes to mind is setting this property as lazy: <property name="Content" lazy="true"/> But there seems to be no difference in the SQL generated by NHibernate. My question is, how do lazy properties behave in NHibernate? Is there some kind of type limitations I could be missing? Should I take a different approach altogether? Using HQL's new Class(column1, column2) approach works, but lazy properties sounds like a simpler solution. It's perhaps worth mentioning I'm using NHibernate 2.1.2GA with the Castle DynamicProxy. Thanks!

  • Can it be done?

    - by bzarah
    We are in design phase of a project whose goal is replatforming an ASP classic application to ASP.Net 4.0. The system needs to be entirely web based. There are several new requirements for the new system that make this a challenging project: The system needs to be database independent. It must, at version 1.0, support MS SQL Server, Oracle, MySQL, Postgres and DB2. The system must be able to allow easy reporting from the database by third party reporting packages. The system must allow an administrative end user to create their own tables in the database through the web based interface. The system must allow an administrative end user to design/configure a user interface (web based) where they can select tables and fields in the system (either our system's core tables or their own custom tables created in #3) The system must allow an administrative end user to create and maintain relationships between these custom created tables, and also between these tables and our system's core tables. The system must allow an administrative end user to create business rules that will enforce validation, show/hide UI elements, block certain actions based on the identity of specific users, specific user groups or privileges. Essentially it's a system that has some core ticket tracking functionality, but allows the end user to extend the interface, business rules and the database. Is this possible to build in a .Net, Web based environment? If so, what do you think the level of effort would be to get this done? We are currently a 6 person shop, with 2.5 full time developers.

  • Detecting inconsistent revisions of shared sources in SVN

    - by maxim1000
    I have an SVN repository containing several components: LibraryA LibraryB - depends on LibraryA Application - depends on LibraryB and LibraryA More detailed structure (branches and tags are not related to the problem): LibraryA LibraryA_code LibraryB LibraryB_code svn:externals to a fixed revision R1 of LibraryA_code Application Application_code svn:externals to a fixed revision R2 of LibraryA_code svn:externals to a fixed revision R3 of LibraryB_code The problem I'm trying to solve is automatic detection of situation when R2 differs from R1 (breaking expectations of LibraryB_code) and notification about this (e.g. build failure). I'll describe in an answer the only solution which I see for now, but I hope for something more elegant :) Environment: Windows, Visual Studio, SVN.
