• Where does static variable work in C# page. At Application level or Page Level

  - by Shantanu Gupta

  I had an interview today and every thing was going very good, but then an interviewer asked me a question Where Does Static Variable Work in C#- At Application Level or At Page Level. I was not very much clear about this answer as I only knew that static variables are stored on heap and I didn't knew anything about web related thing about it. Then tried to make me more clear by giving an example that in a page I am using static variable and three users are accessing the page one of the user updates the value of static variable, What value will be visible to remaining two users an old copy or the update will be reflected.

• Parant/master project in git

  - by jriff

  Hi all I have a project "A" that is a Git repo. I would like to be able to make multiple copies of project A (B and C), and modify them for clients. "A" is the master so sometimes when I do new functionality i would like to be able to pull them from B or C. But some commits should just stay in A and never leave :-) How do I do that with Git? That is: how to copy A? (Clone?) how to get specific commits into B and C? Please keep in mind that this all happening locally - not on GitHub. I use OS X. Regards, Jacob.

• Android service puts multiple instances of an activity in the history

  - by HenryAdamsJr

  I'm making a music player. When you press play, it loads a notification into the OnGoing section. When you go anywhere else in the system, I want the music to keep playing. All of this is fine. The problem is that when I relaunch my activity from the Notification, it adds a task to the history stack each time, so if I hit back, I have to see the instance of Activity B from where I pressed play, and from every time I clicked on the notification to go back to Activity B. I want the instance of Activity B that I launch from the notification (via the service) to be the only copy of that Activity in the history. I've been playing around with various Intent flags and Activity attributes in the manifest, but I haven't found the proper combination.

• How can I replace ” with " in ASP.NET SQL?

  - by vamsivanka

  I am trying to run this SQL from ASP.NET 2005 but am getting an invalid SQL error because it has a weird character ” in it. In my code I am trying to replace ” with " but it is not doing it as the special character in the replace command is changing to ". Query: insert into userquery(description) values ('In fact, Topeka Google Mayor Bill Bunten expressed it best: “Don’t be fooled. Even Google recognizes that all roads lead to Kansas, not just yellow brick ones.”') If I copy and execute this in mysql it is working good. How can I solve this problem?

• How to move iframe along the DOM without losing it's content?

  - by Beck

  Is it possible? I have tried to move it, but iframe contents dissapear. Tried to get contents of iframe and place them in the new place but all handlers ofc dissapear. Tried to do the same, but with new jQuery 1.4.2 feature, that clones all events along with it. But it doesn't work :) So I have decided to ask here for help. How to move the damn iframe to another place in the document without losing it's contents? ^_^ Thanks Added: txtad_iframe = ad_container.find('iframe'); its_contents = txtad_iframe.contents(); its_body = its_contents.find("div:first").clone(true).insertAfter(cthis.find('#photos')); new_ad.append(its_body); Here i'm trying to copy contents to new ad container. But it doesn't work. Context banner doesn't react on click event. I have tried to move ad_container to container, but iframe body content dissapears.

• Do you know any build systems with decent support for parallelization?

  - by dahpgjgamgan

  Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

• Javascript clone form?

  - by user202987

  I need to copy a form information with all types of elements and send it with AJAX. Tried these: 1. cloneNode on the form. - Doesn't work with IE, only copies text stuff properly. cloneNode on each element. Doesn't work with IE, only copies text stuff properly. Making new textareas for each element, and copying the value in. Doesn't work for textareas in IE, formatting is lost. I imagine a combination of those 3 would work for IE and FF but is there any decent solution to this? Shortness of code is a priority.

• MySQL Full-text Search Workaround for innoDB tables

  - by Rob

  I'm designing an internal web application that uses MySQL as its backend database. The integrity of the data is crucial, so I am using the innoDB engine for its foreign key constraint features. I want to do a full-text search of one type of records, and that is not supported natively with innoDB tables. I'm not willing to move to MyISAM tables due to their lack of foreign key support and due to the fact that their locking is per table, not per row. Would it be bad practice to create a mirrored table of the records I need to search using the MyISAM engine and use that for the full-text search? This way I'm just searching a copy of the data and if anything happens to that data it's not as big of a deal because it can always be re-created. Or is this an awkward way of doing this that should be avoided? Thanks.

• SSRS and cached reports

  - by Tabloo Quijico

  Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

• My program is getting a false positive from AVG.

  - by JimDel

  My program is getting a false positive from AVG. Its just our companies branded version of Ultra VNC. Its only this one company that's identifying it as a virus and we've been using the same copy of that program for almost a year. I know its possible to tell this Anti Virus program the VNC client is safe, but I can't do that for all of our clients. I've tried to find a way to contact this company to see if they can do something to prevent this from happening, but I'm not getting anywhere. Has anyone who's experienced this issue with their software, found a solution? Thanks

• Returning std::vector by value

  - by deft_code

  It is oft said that in C++11 it is sane to return std::vector by value. In C++03 this was mostly true as RVO should optimize away the copy. But that should scared most developers away. In C++11 will a returned std::vector local variable always be moved? What if that vector is a member of a local variable instead of a local variable itself? Obviously returning a global variable will not be moved. What other cases will it not be moved?

• Automatic VisualState Manager in Silverlight

  - by Matt

  If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the code behind or auto generated style area does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! Is the only way to change a button's state have to be done the code behind using the VisualStateManager.GoToState method, or can you change it much like CSS does (a:hover) using the VisualStateManager? From my experience, setting just doesn't seem to do the trick.

• Signed and unsigned, and how bit extension works in C

  - by hatorade

  unsigned short s; s = 0xffff; int i = s; How does the extension work here? 2 larger order bytes are added, but I'm confused whether 1's or 0's are extended there. This is probably platform dependent so let's focus on what Unix does. Would the two bigger order bytes of the int be filled with 1's or 0's, and why? Basically, does the computer know that s is unsigned, and correctly assign 0's to the higher order bits of the int? So i is now 0x0000ffff? Or since ints are default signed in unix does it take the signed bit from s (a 1) and copy that to the higher order bytes?

• How to import datarow from one dataset to another?

  - by Disciple

  Hi, I want to copy the row to the new dataset if the previous value in second column isn't the same as the current one (i.e this dataset should have rows with unique values): DataTable tbl = new DataTable(); DataTable tmpTable = ds.Tables[0]; for( var rowIndex = 0; rowIndex < ds.Tables[0].Rows.Count; rowIndex++ ) { object value = null; foreach (DataRow x in tbl.Rows) { if (ds.Tables[0].Rows[rowIndex][1] == x[1]) { value = ds.Tables[0].Rows[rowIndex][1]; break; } } // value already exists if (value == null) { tbl.ImportRow(ds.Tables[0].Rows[rowIndex]); } } How to do this correctly? Maybe one loop instead 2?

• const ready only local copies

  - by robUK

  Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a ready-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on ready-only local copies, as it confirms to anyone reading my code that it is a ready-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

• CALayer not obeying object ownership rules?

  - by eaigner

  I have a custom CALayer - UIProgressLayer - for simulating a progress bar. There is a dispatched GC timer involved to animate its intermediate state. So thats the layer I'm talking about here, although i don't think the problem is restricted to this particular subclass because a CALayer with only the -release and -dealloc overridden produces the same outcome. The problem is when i send this layer, for instance, a theLayer.opacity = 0.5f a -release message is sent to the layer, thus deallocating my layer. Why is this happening? Has it something to do with how the whole CA system works? But it still has to obey the object ownership rules right? I was thinking maybe it creates a copy of that layer for the fading, but that's not the case.

• How to force Maven to download maven-metadata.xml from the central repository?

  - by Alceu Costa

  What I want to do is to force Maven to download the 'maven-metadata.xml' for each artifact that I have in my local repository. The default Maven behaviour is to download only metadata from remote repositories (see this question). Why I want to do that: Currently I have a remote repository running in a build machine. By remote repository I mean a directory located in the build machine that contains all dependencies that I need to build my Maven projects. Note that I'm not using a repository manager like Nexus, the repository is just a copy of a local repository that I have uploaded to my build machine. However, since my local repository did not contain the 'maven-metadata.xml' files, these metadata files are also missing in the build machine repository. If I could retrieve the metadata files from the central repository, then it would be possible to upload a working remote repository to my build machine.

• What is the best way to sync multiple client SqlServers to one MS SqlServer 2005?

  - by user605055

  I have several client databases that use my windows application. I want to send this data for online web site. The client databases and server database structure is different because we need to add client ID column to some tables in server data base. I use this way to sync databases; use another application and use C# bulk copy with transaction to sync databases. My server database sql server is too busy and parallel task cannot be run. I work on this solution: I use triggers after update, delete, insert to save changes in one table and create sql query to send a web service to sync data. But I must send all data first! Huge data set (bigger than 16mg) I think can't use replication because the structure and primary keys are different.

• How can I send an std::vector<std::string> over a UNIX socket?

  - by Mike

  For my application, I need to be able to send an std::vector<std::string> over a UNIX socket(local), and get a copy of the vector on the other end of the socket. What's the easiest way to do this with O(1) messages relative to the size of the vector(i.e. without sending a message for each string in the vector)? Since this is all on the same host, and because I control both ends of the socket, I'm not concerned with machine-specific issues such as endinness or vector/string representation.

• How to include a Custom list in one Sharepoint site in to another as a web part?

  - by Rakhitha

  I have two share point web sites. One is a child web site of the other. For example if my first site is myweb1, other one is myweb1/myweb2. I have a custom list created in myweb1. I want to include that as a web part in number of web pages in both myweb1 and myweb1/myweb2 sites. Including the web part in the same site which contains the custom list is not a problem. But how do I include it in the other site. The web part does not show up in the list. I dont want to copy the content of custom list. I want pages in both sites that have included this list as a web part to be updated whenever the list content is changed. Any ideas?

• Recommended place for pre-translated Zend Framework resources

  - by Exception e

  Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?

• Do you know of a C dictionary that supports COW transactions?

  - by Tim Post

  I'm looking for a key - value dictionary library written in C that supports a theoretically unlimited number of cheap transactions. I'd like to have one dictionary in memory, with hundreds of threads starting transactions, possibly modifying the dictionary, ending (completing) the transaction or potentially aborting the transaction. Only 50% of the time will these threads actually modify the dictionary. Most dictionary transaction implementations that I've seen copy always, instead of copying on write, whenever a transaction is started. Given the expected size ( 1GB) of the dictionary, I'm hoping to find something that COWs only when something is actually changed during a transaction. I'm also hoping for something that is packaged by most major GNU/Linux distributions. Any suggestions or links are very much appreciated.

• Adding java source (.java files) to test jar in Maven

  - by user320550

  Hi all, I'm making use of my pom.xml and am was able to generate the jar for src/main/java (say app.jar) as well as for src/test/java (say app-test.jar). I was also able to include my java sources as part of the app.jar (i.e. have both my .class as well as my .java files in the jar). However for my app-test.jar, i'm not able to include my .java files in it. This is my pom.xml: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>my-app</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> </resource> </resources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.1</version> <executions> <execution> <phase>package</phase> <goals> <goal>test-jar</goal> </goals> <configuration> <includes> <include>src/test/java</include> </includes> </configuration> </execution> </executions> </plugin> </plugins> </build> </project> Any help would be appreciated.
