• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

• Oracle Triggers Query..

  - by AGeek

  Lets consider a Table STUD and a ROW-Level TRIGGER is implemented over INSERT query.. My scenario goes like this, whenever a row is inserted, a trigger is fired and it should access some script file which is placed in the hard disk, and ultimately should print the result. So, is this thing is possible? and if yes, then this thing should exist in dynamic form, i.e. if we change the content of script file, then the oracle should reflect those changes as well. I have tried doing this for java using External Procedures, but doesn't feel that much satisfied with the result that i wanted. Kindly give your point-of-view for this kind of scenario and ways that this can be implemented.

• Open source framework à la Microsoft Sync Framework suggestions?

  - by drskol

  We are implementing a warehouse management system atop an open source stack (Java, web services & friends). In this system, we want to integrate many mobile devices which should also be capable of adequate online/offline functionality, e.g. preparing database inserts while a mobile device is temporarily unconnected, and performing them on the backend database when reconnected. For a .NET stack, Microsoft Sync Framework would be a perfect solution, e.g. to do database replication and hoarding. Can anyone suggest an open source alternative to the MS Sync Framework and possibly describe his experiences with it? Thanks in advance for any answers.

• Updating display of elements on the web page without refreshing the whole page

  - by ivorossi3

  Last time I coded a web application was almost 10 years ago. I used Java/JSP/HTML/CSS etc. I've been coding non-web applications only ever since. When I look at modern sites now (like this one), I realize how my web development skills are obsolete. Maybe the most obvious "feature" that I wouldn't know how to implement now is the update of elements on the page after user input without having to refresh the whole page (e.g. the voting/downvoting here updates the vote count without reloading the whole page). What are the basic technologies behind this?

• JSF - database character encoding

  - by wheelie

  Hi there, I have a Java Web application using GlassFish 3, JSF2.0 (facelets) and JPA (EclipseLink). The problem I'm facing, is that if I'm saving entities to the database with the update() method, String data loses integrity; '?' is shown instead of some characters. The server, pages and database is/are configured to use UTF-8. After I post form data, the next page shows the data correctly. Furthermore it "seems" in debug that the String property of the current entity stores the correct value too. Dunno if NetBeans debug can be trusted; might be that it decodes correctly, however it's incorrect. Any help would be appreciated, thanks in advance! Daniel

• How to disable Eclipse's behavior of maximizing editor when double clicking a tab?

  - by Steve Kehlet

  I recently updated my Eclipse (now running 20100218-1602), and I've found whenever I click around quickly between tabs on the tab bar, it will sometimes maximize the editor and hide the PHP Explorer to the left. After researching a little, this appears to be a feature of double clicking a tab. So I guess it's my fault, I'm sure I'm clicking around too fast and mistakenly double clicking a tab, but it happens often enough on what I'd consider a normal editing session that I've come to absolutely loathe it, and even after the usual googling due diligence cannot figure out how to turn it off. From this post (http://stackoverflow.com/questions/594659/eclipses-tab-double-click-on-visual-studio) someone mentions the Window.AutoHideAll shortcut, however that seems to only be for assigning keyboard shortcuts--this is a mouse click thing. But maybe it's a clue. I can't find anything relevant under Eclipse - Preferences - PHP. I don't think it's specific to PHP because if I switch to the Java perspective, double clicking a tab hides the Package Explorer. Any suggestions are appreciated, thanks!

• updating a shape in scene with a for loop using javafx

  - by Susanta

  Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

• What are the exact versions of stuff you have to install in order to be able to step-debug a Scala p

  - by Alex R

  How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence, the more detailed re-statement of the question is appropriate: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

• How to prepare an interview for Ruby on Rails developer position?

  - by Snehal

  Background about myself: I have about 3 years experience working in Java/J2EE. I am currently pursuing MS in Software Engineering at a reputed university. I have done several classwork projects on Ruby on Rails and can be considered at Intermediate level expertise with ROR. I have an interview coming up next week for a Ruby on Rails developer position at a startup. I have already prepared all the basics of Ruby on Rails but didn't get a lot input on the questions asked for ROR developers. Can you guys help me with the preparation? Any materials, suggestions would be welcome.

• Can I pass a string variable into an <a href> tag for a website link?

  - by Joseph

  I am somewhat new to web developing, so I am trying to learn along the way. I have a div that is 500 x 500. Inside of that div I have two divs that are each 250x500. So my outer div is filled up with the two inner divs. I have it setup so that when I click on the first div (the left one) a java script is called, and a prompt pop up box asks for a website URL which is then stored inside of a string variable. How can I make it so that the second div (the right one) takes the string variable from the alert box from the left div and puts it into an a href tag so that I can link to the website from the right div? Can a a href tag accept a value from a variable for its link? Maybe I am going about this all wrong, is there a better way I should be approaching this? Any help is appreciated!!

• UML and Documenting Simple Diagrams

  - by Jason

  As part of a rewrite of an old Java application into C#, I'm writing an actual Software Design Specification. A problem I run into is when a method is too simple to bother with a Sequence Diagram (it doesn't interact with other objects). As an example, I have a simple POJO called Item, containing the following method: public String getCategoryKey() { StringBuffer value = new StringBuffer("s-"); value.append(this.getModelID()); value.append("-c"); return value; } The purpose and the algorithm for the method needs to be documented. However, a sequence diagram is overkill. How would others document it? (I take no credit/blame for the given method, it's very old code and the author "forgot" to put their name in the Javadoc).

• Jython: Is there any difference between adding to sys.path vs passing -D?

  - by trinth

  I have a python application that is trying to load some Java libraries (specifically Axis2 web services). When I add the necessary jars in Eclipse via PyDev Project Source Folders, everything seems to work fine. However, I want to be able to do this at run time by adding to sys.path, but then my application doesn't seem to work. In both cases I can load the jars just fine, but something must be different for there to be different results. My question is, is there a difference between adding jars via the sys.path at run time with sys.path.append() versus passing -D to the jython interpreter?

• How do you find the last element of an array while iterating using a foreach loop in php ?

  - by Vaibhav Kamble

  I am writing a sql query creator using some parameters. While doing that ,I came across this problem. In java , Its very easy to detect the last element of an array from inside the for loop by just checking the current array position with the array length. for(int i=0; i< arr.length;i++){ boolean isLastElem = i== (arr.length -1) ? true : false; } php has some different fashion. They have non integer indexes to access arrays. So you must iterate over an array using foreach loop. But it becomes very problematic when you need to take some decision (in my case to append or/and parameter while building query). I am sure there must be some standard way of doing this. How do you solve this problem normally in php ?

• Scala Eclipse IDE suddenly ignoring breakpoints

  - by malsmith

  I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code. Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck. I would greatly appreciate ideas for fixes. Rather frustrating as the initial experience with 2.8 was really great.

• C# programmer - necessary to learn C/C++?

  - by Kurresmack

  Hey, I have been programming now for a couple of years. But never any low level language. I started off with some java and some VB. Then I went over to VB.NET and now for a while I have been writing C#. As you see, I have never written any low level language where I had to deal with memory management. Is this something I should do, like a route of passage that every programmer should go through? I am a bit keen on trying to perhaps writing in assembler directly. This would suit me personally good as I have 2 parents that have been writing assembler for ages. Is it necessary for a professional programmer these days to know how to manually manage memory?

• Constructor with non-instance variable assistant?

  - by Robert Fischer

  I have a number of classes that look like this: class Foo(val:BasicData) extends Bar(val) { val helper = new Helper(val) val derived1 = helper.getDerived1Value() val derived2 = helper.getDerived2Value() } ...except that I don't want to hold onto an instance of "helper" beyond the end of the constructor. In Java, I'd do something like this: public class Foo { final Derived derived1, derived2; public Foo(BasicData val) { Helper helper = new Helper(val); derived1 = helper.getDerived1Value(); derived2 = helper.getDerived2Value(); } } So how do I do something like that in Scala? I'm aware of creating a helper object of the same name of the class with an apply method: I was hoping for something slightly more succinct.

• Weird behavior in referring to global variable. Is this a bug in javascript? Surely it isn't!

  - by Chandan .

  Consider the following piece of code. <html> <body> <script> var x = 5; //globally declared function showX() { alert("x="+x); //trying to display global value var x=10; //trying to create and initialize a local x } </script> <input type = "button" value="Show X" onclick="showX()"> </body> </html> The alert statement shows 'x=undefined'. And doesn't print the global value of x as expected. An equivalent java code would display 5! So, is it a bug? If not then how does one explain that behavior?

• Which relational databases exist with a public API for a high level language?

  - by Jens Schauder

  We typically interface with a RDBMS through SQL. I.e. we create a sql string and send it to the server through JDBC or ODBC or something similar. Are there any RDBMS that allow direct interfacing with the database engine through some API in Java, C#, C or similar? I would expect an API that allows constructs like this (in some arbitrary pseudo code): Iterator iter = engine.getIndex("myIndex").getReferencesForValue("23"); for (Reference ref: iter){ Row row = engine.getTable("mytable").getRow(ref); } I guess something like this is hidden somewhere in (and available from) open source databases, but I am looking for something that is officially supported as a public API, so one finds at least a note in the release notes, when it changes. In order to make this a question that actually has a 'best' answer: I prefer languages in the order given above and I will prefer mature APIs over prototypes and research work, although these are welcome as well.

• What frameworks exist for data subscription and update?

  - by Timothy Pratley

  There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view. In the client side code I would like the users list to be updated by the framework itself, raising changed events such that it will be redrawn - similar to 'cells' or dataflow. I am looking specifically for a .NET or java implementation.

• I know the big picture but can't put it in place

  - by Simbilim

  Hi, I'm interested in web development and by that I mean the bigger projects like facebook or twitter. I know the basics of java, css, php and mysql. I know there is a lot more out there. I read about it. But I don't know what the purpose is and how to put in place. Things like: Scribe, thrift, casandra, Unix/Linux, shell/perl/python scripting, PostgreSQL, MongoDB, non-relational NoSQL datastores, JVM, nginx I want to know why they need it, how they use it and what te purpose is. What I need is a book like technical background of facebook for dummies or so. Are there any books or websites that explain this from scratch? Thank you!

• Android, how to make two buttons next to each other with the same width

  - by user3674127

  Im trying to place two buttons on the xml next to each other and I want them both to be the same size(half from the width of the screen) - this is my xml: <LinearLayout android:layout_width="fill_parent" android:orientation="horizontal" android:id="@+id/linearLayout2" android:layout_height="fill_parent" android:gravity="bottom" android:weightSum="2"> <Button android:layout_weight="1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/bAddDelete" /> <Button android:layout_weight="1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/bMainMenu" /> </LinearLayout> Everything works well, but when im changing the text in java, the width is changing, how can I make them the same size? Thanks

• Validate XML instance document against WSDL

  - by Ice09

  Hi, I can easily validate a XML document against a XML Schema, eg. with XMLSpy or programmatically. Is it possible to do this with a WSDL file? It does not seem possible with XMLSpy or any other XML tool I know. For me the only possibility right now is to do it programmatically, eg. by generating Java code from the WSDL and starting a request, which is then marshalled correctly. If there is no tool / easy programmatic approach, is there a tool which can extract XML Schema from the WSDL? Best
