• How to make IIS wait for WCF service gets ready?

  - by Kamarey

  I have a WCF service hosted in IIS 7. It takes some minutes until this service finish to load its data and ready for external calls. Data loads in internal thread. The problem is that from IIS point the service is ready just after it was activated (by some call), and it process a request without waiting for data to be loaded. Is it possible to tell IIS that the service is still loading and make this service unavailable for requests? No problem if such request will throw an exception.

• Adding mouse events to dynamically loaded SWF

  - by Josamoto

  I am loading an external SWF using the Loader class, and adding it to the stage with addChild. When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires. Is there a specific way to add listeners to externally loaded movie clips? My code looks somewhat like this: var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target); The target shows up on the display, but the CLICK event is completely ignored.

• Visual Studio Setup Project

  - by pm_2

  I’m trying to use a Visual Studio Setup Project to deploy a C# Application. In a VS Setup project, is it possible to dynamically change the application folder before a project is installed, or even to add any code behind the set-up project at all? What I am trying to achieve is an msi that runs, calculates the installation directory based on some external factors and then installs to that directory. I then want it to run the application immidiately. The objective for this is no user intervention throughout.

• Is there a single Git command to get the current tag, branch and commit?

  - by Koraktor

  I'm currently using a collection of three commands to get the current tag, branch and the date and SHA1 of the most recent commit. git describe --always --tag git log -1 --format="%H%n%aD" git rev-parse --abbrev-ref HEAD Which will output something like: 1.2.3-gdeadbeef deadbeef3b8d90071c24f51ac8f26ce97a72727b Wed, 19 May 2010 09:12:34 +0200 master To be honest, I'm totally fine with this. But I'm using these commands from Maven and anyone who'd used Maven before, knows how much things like external commands bloat the POM. I just want to slim down my pom.xml and maybe reduce execution time a bit.

• check whether fgets would block

  - by lv

  Hi, I was just wondering whether in C is it possible to peek in the input buffer or perform similar trickery to know whether a call to fgets would block at a later time. Java allows to do something like that by calling BufferedReader.ready(), this way I can implement console input something like this: while (on && in.ready()) { line = in.readLine(); /* do something with line */ if (!in.ready()) Thread.sleep(100); } this allows an external thread to gracefully shutdown the input loop by setting on to false; I'd like to perform a similar implementation in C without resorting to non portable tricks, I already know I can make a "timed out fgets" under unix by resorting to signals or (better, even though requering to take care of buffering) reimplement it on top of recv/select, but I'd prefer something that would work on windows too. TIA

• I have to generate PL/SQL using Java. Most of the procedures are common. Only a few keeps changing.

  - by blog

  I have to generate PL-SQL code, with some common code(invariable) and a variable code. I don't want to use any external tools. Some ways that I can think: Can I go and maintain the common code in a template and with markers, where my java code will generate code in the markers and generate a new file. Maintain the common code in static constant String and then generate the whole code in StringBuffer and at last write to file. But, I am not at all satisfied with both the ideas. Can you please suggest any better ways of doing this or the use of any design patterns or anything? Thanks in Advance.

• How to call an xslt transform into an xsl stylesheet

  - by Mycol

  I have written an xslt that reads some xml file names and does some operations on them. I use a for-each to work them one-by-one. I have each path inside a parameter $path. But now I would like to output the result of applying an external stylesheet to those files. I would write something like <div> <something like xsl-transform($extern-xslt,$path)> </div> to have the result tree of the transformation inside the main html output. It is possible?

• using partials in view helpers

  - by takeshin

  Creating custom Zend View helpers I often end up with something like: // logic here if ($condition) { $output = <<<EOS... } else { $output = <<<EOS... } or using switch. Then to eliminate this, I create setPartial(), getPartial() and htmlize() for using external .phtml's. This is not the best solution, because partials do not support doctype changing. Is there any better solution, than creating abstract class handling this common case? Are there any ready Zend solutions for this case? Separate view helper for each case? And where to put common code?

• Does anybody have practice in programming PCMEF - architectures?

  - by Erkki

  PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

• Generate MySQL data dump in SQL from PHP

  - by Álvaro G. Vicario

  I'm writing a PHP script to generate SQL dumps from my database for version control purposes. It already dumps the data structure by means of running the appropriate SHOW CREATE .... query. Now I want to dump data itself but I'm unsure about the best method. My requirements are: I need a record per row Rows must be sorted by primary key SQL must be valid and exact no matter the data type (integers, strings, binary data...) Dumps should be identical when data has not changed I can detect and run mysqldump as external command but that adds an extra system requirement and I need to parse the output in order to remove headers and footers with dump information I don't need (such as server version or dump date). I'd love to keep my script as simple as I can so it can be hold in an standalone file. What are my alternatives?

• Merging getComputedStyle and evaluate in Greasemonkey

  - by Keheliya Gallaba

  I need to get all the text nodes with a certain font-face in a page to an array. I tried.. textnodes = document.evaluate("//* [@style='font-family: foo;']//text()[" + "not(ancestor::script) and not(ancestor::style)]", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); and textnodes = document.evaluate("//* [@face='foo']//text()[" + "not(ancestor::script) and not(ancestor::style)]", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); But these does not work with pages that is styled by external CSS files. Seems getComputedStyle() is the way to go. I think what I need is something like.. var tags = document.getElementsByTagName('*'); for (var i in tags) { var style = getComputedStyle(tags[i], ''); if (style.fontFamily.match(/foo/i)) { textnodes.push(tags[i]); } } But text nodes were not returned in this method. Is there anyway I can use a hybrid of xpath evaluate() and getComputedStyle() or any other way to achieve this?

• Qt/C++ event loop exception handling

  - by Georg

  I am having an application heavily based on QT and on a lot of third party libs. THese happen to throw some exceptions in several cases. In a native Qt App this causes the application to abort or terminate. Often the main data model is still intact as I am keeping it in pure Qt with no external data. So I am thinking that I could also just recover by telling the user that there has occured an error in this an that process and he should save now or even decide to continue working on the main model. Currently the program jsut silently exits without even telling a story. Please help.

• What is the fastest way to write hundreds of files to disk using C#?

  - by Ehsan

  My program should write hundreds of files to disk, received by external resources (network) each file is a simple document that I'm currently store it with the name of GUID in a specific folder but creating hundred files, writing, closing is a lengthy process. Is there any better way to store these amount of files to disk? I've come to a solution, but I don't know if it is the best. First, I create 2 files, one of them is like allocation table and the second one is a huge file storing all the content of my documents. But reading from this file would be a nightmare; maybe a memory-mapped file technique could help. Could working with 30GB or more create a problem?

• cross domain DOM access and manipulation in Java ?

  - by gaqer

  In my Java app, how can I incorporate the browser (which loads and renders URLs) in Swing and access it's DOM and manipulate HTML ? How can you embed such browser in a Rich Internet Application and access it's DOM ? More specifically, Vaadin ? Is there a HTTP proxy class that can load an external URL, and render it to the user ? This was what I was doing on LAMP stack....but I want to switch to Vaadin or some Java web framework where I can just use Java to do everything from server-side to client-side logic design, so I can focus more on application logic. (aka looking for developer friendly frameworks like Vaadin). Thank you and have a great weekend !

• Why is it so hard to build a gtk programe without console using cmake in windows?

  - by Runner

  I'm following the tuto: http://zetcode.com/tutorials/gtktutorial/firstprograms/ It works but each time I double click on the executable,there is a console which I don't want it there. How do I get rid of that console? I tried this: add_executable(Cmd WIN32 cmd.c) But got this fatal error: MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup Cmd.exe : fatal error LNK1120: 1 unresolved externals While using gcc directly works: gcc -o Cmd cmd.c -mwindows .. I'm guessing it has something to do with the entry function: int main( int argc, char *argv[]),but why gcc works? How can I make it work with cmake?

• Linkage Error with Inherited Class

  - by metdos

  I have static library and another program which uses it. In the static library If I define header without inheretence it works fine. class TcpCommunication On the other hand If I use inheretence with a QT class, class TcpCommunication:public QTcpServer I'm getting linkage error when I compiling code which uses this static library. >MStoDKAPId.lib(TcpCommunication.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __thiscall QTcpServer::~QTcpServer(void)" (__imp_??1QTcpServer@@UAE@XZ) referenced in function "public: virtual __thiscall TcpCommunication::~TcpCommunication(void)" (??1TcpCommunication@@UAE@XZ) What can be the problem? Thanks.

• Force download menu for remote files

  - by o-logn

  Hey, I would like users to upload links on my site. When another user clicks on the link (e.g. PDF file), then I would like the download popup to show instead of actually displaying the PDF in browser. I know I can use Response.AddHeader/Response.WriteFile to achieve this, but the WriteFile method required a virtual path. However, the links uploaded by the user will be pointing to external servers. Can I still force the download popup to show and, if so, what would be the most efficient way of doing it? Thanks for any advice

• Options for storing large text blobs in/with an SQL database?

  - by kdt

  Hi, I have some large volumes of text (log files) which may be very large (up to gigabytes). They are associated with entities which I'm storing in a database, and I'm trying to figure out whether I should store them within the SQL database, or in external files. It seems like in-database storage may be limited to 4GB for LONGTEXT fields in MySQL, and presumably other DBs have similar limits. Also, storing in the database presumably precludes any kind of seeking when viewing this data -- I'd have to load the full length of the data to render any part of it, right? So it seems like I'm leaning towards storing this data out-of-DB: are my misgivings about storing large blobs in the database valid, and if I'm going to store them out of the database then are there any frameworks/libraries to help with that? (I'm working in python but am interested in technologies in other languages too)

• Linking error in OMNeT++ using Boost serialization library

  - by astriffe

  I'm very new to OMNeT++ and I'd like to use the serialization-library contained in the boost framework. However, when trying to use it, I get quite many errors such as: Description Resource Path Location Type undefined reference to `boost::archive::archive_exception::~archive_exception()' OmCCN line 36, external location: /home/alexander/UniBE/BT/simulator/boost-compiledLibs /include/boost/serialization/throw_exception.hpp C/C++ Problem . I guess the problem is that I didn't yet link the compiled library in OMNeT. I've had a look at the makefile but any changes there are worthless since it is generated automatically by makemake. Furthermore, trying to access the menu item 'makemake' in project properties OMNeT++ IDE throws an error (The currently displayed page contains invalid values). Can anyone give me a hint concerning what the error could cause or how to link the compiled library correctly? Any hints are very appreciated! cheers alex

• How to notify SIP client when there is an incoming call on another phone

  - by fmunkert

  Hi, is it possible to notify a SIP client when there is an incoming call on another phone? I know that there are the SUBSCRIBE and NOTIFY commands but I have found no event package for signaling incoming calls. Background: for a SIP-capable telephony system, I would like to provide an application that displays information about the caller (e.g. name, address, contracts, etc.) when the phone rings. The phones are external to the PC; they are not soft-phones. -Frank

• How to exit a process run with Ruby if it takes more than 5 seconds?

  - by Alex

  I'm implementing a checking system in Ruby. It runs executables with different tests. If the solution is not correct, it can take forever for it to finish with certain hard tests. That's why I want to limit the execution time to 5 seconds. I'm using system() function to run executables: system("./solution"); .NET has a great WaitForExit() method, what about Ruby?. Is there a way to limit external process' execution time to 5 seconds? Thanks

• How do I transfer configuration data into injected objects?

  - by louis

  I used to use Spring.Net and want to switch to Ninject 1.5 (I have to use .NET2, since some unlucky guy like me still needs to consider users working with win 2k). I used to have everything done in xml and only invoke the container during startup. In this way, only very limited codes are depending on container. I have scenarios like this and I wonder how to do the same in Ninject. I have external config file, which are the items the end users can change basing on their environment/preferences. And some of my objects depends on those values to initialize. Mostly they are primary values, but some times can be list/dictionaries/etc.

• How to detect an active x component that does not respond any more?

  - by koschi

  My application is written in C++ and uses the Qt framework. I use the QAxWidget class to access an active x component. Now I need some kind of mechanism that notifies my application each time the active x component has crashed or does not respond any more (due to dead lock or infinite loop). (1) can easily been done by watching the external process of the active x component. But maybe there is a more elegant approach? But how can (2) be implemented?

• Why is volatile not considered useful in multithreaded C or C++ programming?

  - by Michael E

  As demonstrated in this answer I recently posted, I seem to be confused about the utility (or lack thereof) of volatile in multi-threaded programming contexts. My understanding is this: any time a variable may be changed outside the flow of control of a piece of code accessing it, that variable should be declared to be volatile. Signal handlers, I/O registers, and variables modified by another thread all constitute such situations. So, if you have a global int foo, and foo is read by one thread and set atomically by another thread (probably using an appropriate machine instruction), the reading thread sees this situation in the same way it sees a variable tweaked by a signal handler or modified by an external hardware condition and thus foo should be declared volatile (or, for multithreaded situations, accessed with memory-fenced load, which is probably a better a solution). How and where am I wrong?

• jquery carousel

  - by Adam Wright

  Hi, I'm looking for a jquery carousel to contain image with the following requirements: must run on auto must not pause must be able to pause on image hover must have external controls that once clicked change the direction of the carousel. must be able to fadeout buttons when the carousel is moving in that direction. I've looked at jcaursel and jcaousellite but both have a pause of in auto mode or you have to specify how many items to slide. I just want it to move continously like a news ticker. Any suggestions on how to achieve this or how to customise jcaurousel or jcarouselite?
