  • Visual Studio 2008 not detecting Errors while coding

    - by mouthpiec
    Hi, I just installed VS on another PC, but this time, while I am coding, it is not marking syntax errors while I am coding..... I need to press F6 to get the errors. Normally when for example typing the line below, I get 's' underlined saying that there is a mismatch. Any ideas how I can enable this option? string s = 4;

  • The best JSF coding pattern for editing JPA entities using @RequestScoped only

    - by AlanObject
    I am in a project where I will write a lot of pages like this, so I want to use the most efficient (to write) coding pattern. Background: In the past I have used CODI's @ViewAccessScoped to preserve state between requests, and more recently I have started using flash scoped objects to save state. I can't use JSF @ViewScoped because I use CDI and they don't play well together. So I want to see if I can do this with only @RequestScoped backing beans. The page is designed like this (the p namespace is Primefaces): <f:metadata> <f:viewParam name="ID" value="#{backing.id}" /> </f:metadata> .... <h1>Edit Object Page</h1> <h:form id="formObj" rendered="#{backing.accessOK}"> <p:panelGrid columns="2"> <h:outputLabel value="Field #1:"/> <p:inputText value="#{backing.record.field1}" /> (more input fields) <h:outputLabel value="Action:" /> <h:panelGroup> <p:commandButton value="Save" action="#{backing.save}" /> <p:commandButton value="Cancel" action="backing.cancel" /> </h:panelGroup> </p:panelGrid> <p:messages showDetail="true" showSummary="true" /> </h:form> If the page is requested, the method accessOK() has the ability to keep the h:form from being rendered. Instead, the p:messages is shown with whatever FacesMessage(s) the accessOK() method cares to set. The pattern for the bean backing looks like this: @Named @RequestScoped public class Backing { private long id; private SomeJPAEntity record; private Boolean accessOK; public long getId() { return id; } public void setId(long value) { id = value; } public boolean accessOK() { if (accessOK != null) return accessOK; if (getRecord() == null) { // add a FacesMessage that explains the record // does not exist return accessOK = false; // note single = } // do any other access checks, such as write permissions return accessOK = true; } public SomeJPAEntity getRecord() { if (record != null) return record; if (getId() > 0) record = // get the record from DB else record = new SomeJPAEntity(); return record; } public String execute() { if (!accessOK()) return null; // bad edit // do other integrity checks here. If fail, set FacesMessages // and return null; if (getId() > 0) // merge the record back into the data base else // persist the record } } Here is what goes wrong with this model. When the Save button is clicked, a new instance of Backing is built, and then there are a lot of calls to the getRecord() getter before the setID() setter is called. So the logic in getRecord() breaks because it cannot rely on the id property being valid when it is called. When this was a @ViewAccessScoped (or ViewScoped) backing bean, then both the id and record properties are already set when the form is processed with the commandButton. Alternatively you can save those properties in flash storage but that has its own problems I want to avoid. So is there a way to make this programming model work within the specification?

  • How to handle value types when embedding IronPython in C#?

    - by kloffy
    There is a well known issue when it comes to using .NET value types in IronPython. This has recently caused me a headache when trying to use Python as an embedded scripting language in C#. The problem can be summed up as follows: Given a C# struct such as: struct Vector { public float x; public float y; } And a C# class such as: class Object { public Vector position; } The following will happen in IronPython: obj = Object() print obj.position.x # prints ‘0’ obj.position.x = 1 print obj.position.x # still prints ‘0’ As the article states, this means that value types are mostly immutable. However, this is a problem as I was planning on using a vector library that is implemented as seen above. Are there any workarounds for working with existing libraries that rely on value types? Modifying the library would be the very last resort, but I'd rather avoid that.

  • How Do I Pass The Value (Not The Reference) of a JS Variable to a Function?

    - by ryan
    Here is a simplified version of something I'm trying to run: for (var i = 0; i < results.length; i++) { marker = results[i]; google.maps.event.addListener(marker, 'click', function() { change_selection(i); }); } but I'm finding that every listener uses the value of results.length (the value when the for loop terminates). How can I add listeners such that each uses the value of i at the time I add it, rather than the reference to i?

  • How to make dropdownlist show a selected value in asp.net mvc?

  • C++/CLI value class constraint won't compile. Why?

    - by Simon
    Hello, a few weeks ago a co-worker of mine spent about two hours finding out why this piece of C++/CLI code won't compile with Visual Studio 2008 (I just tested it with Visual Studio 2010... same story). public ref class Test { generic<class T> where T : value class void MyMethod(Nullable<T> nullable) { } }; The compiler says: Error 1 error C3214: 'T' : invalid type argument for generic parameter 'T' of generic 'System::Nullable', does not meet constraint 'System::ValueType ^' C:\Users\Simon\Desktop\Projektdokumentation\GridLayoutPanel\Generics\Generics.cpp 11 1 Generics Adding ValueType will make the code compile. public ref class Test { generic<class T> where T : value class, ValueType void MyMethod(Nullable<T> nullable) { } }; My question is now. Why? What is the difference between value class and ValueType?

  • New article available in "SOA Suite Essentials for WLI Users" series: Dynamic Data Lookup in a Busin

    - by simone.geib
    It is my pleasure to announce the publishing of another article in our "SOA Suite Essentials for WLI Users" series: "Dynamic Data Lookup in a Business Process: Meta Data Cache Control in Oracle WebLogic Integration and Domain Value Maps in SOA Suite". This article explains how dynamic data can be retrieved in a business process using Domain Value Maps in SOA Suite and shows the similarities to the WLI XML MetaData Cache Control. Lots of customers have asked about this comparison and I hope they will find it useful. The article follows "Setting Web Service and JCA Adapter Endpoints Dynamically in Oracle SOA Suite" which describes how web services and JCA adapter endpoints in SOA Suite can be changed at run-time, and so completes the use case where a BPEL process writes to a file (via file adapter) and the output directory and the file name are set dynamically. Please let me know what you think about the series and this specific article.

  • Configuring JPA Primary key sequence generators

    - by pachunoori.vinay.kumar(at)oracle.com
    This article describes the JPA feature of generating and assigning the unique sequence numbers to JPA entity .This article provides information on jpa sequence generator annotations and its usage. UseCase Description Adding a new Employee to the organization using Employee form should assign unique employee Id. Following description provides the detailed steps to implement the generation of unique employee numbers using JPA generators feature Steps to configure JPA Generators 1.Generate Employee Entity using "Entities from Table Wizard". View image2.Create a Database Connection and select the table "Employee" for which entity will be generated and Finish the wizards with default selections. View image 3.Select the offline database sources-Schema-create a Sequence object or you can copy to offline db from online database connection. View image 4.Open the persistence.xml in application navigator and select the Entity "Employee" in structure view and select the tab "Generators" in flat editor. 5.In the Sequence Generator section,enter name of sequence "InvSeq" and select the sequence from drop down list created in step3. View image 6.Expand the Employees in structure view and select EmployeeId and select the "Primary Key Generation" tab.7.In the Generated value section,select the "Use Generated value" check box ,select the strategy as "Sequence" and select the Generator as "InvSeq" defined step 4. View image   Following annotations gets added for the JPA generator configured in JDeveloper for an entity To use a specific named sequence object (whether it is generated by schema generation or already exists in the database) you must define a sequence generator using a @SequenceGenerator annotation. Provide a unique label as the name for the sequence generator and refer the name in the @GeneratedValue annotation along with generation strategy  For  example,see the below Employee Entity sample code configured for sequence generation. EMPLOYEE_ID is the primary key and is configured for auto generation of sequence numbers. EMPLOYEE_SEQ is the sequence object exist in database.This sequence is configured for generating the sequence numbers and assign the value as primary key to Employee_id column in Employee table. @SequenceGenerator(name="InvSeq", sequenceName = "EMPLOYEE_SEQ")   @Entity public class Employee implements Serializable {    @Id    @Column(name="EMPLOYEE_ID", nullable = false)    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="InvSeq")   private Long employeeId; }   @SequenceGenerator @GeneratedValue @SequenceGenerator - will define the sequence generator based on a  database sequence object Usage: @SequenceGenerator(name="SequenceGenerator", sequenceName = "EMPLOYEE_SEQ") @GeneratedValue - Will define the generation strategy and refers the sequence generator  Usage:     @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="name of the Sequence generator defined in @SequenceGenerator")

  • How to manage primary key while updating [migrated]

    - by Subin Jacob
    In the following table primaryKeyColumn is primary key. To maintain the data history I always uses the values with WHERE condition(WHERE StatusColumn=1) And will set the StatusColumn to 0 if the data is edited (So that I could keep the previous data). But the problem is, if I update it to 0 , I can't insert the same key to primarykeycolumn since the column validated for primary keys. How can I manage these kind of validations? what the mistake I did in this design? primaryKeyColumn ValueColumn StatusColumn ---------------- ----------- ------------ 2 Name1 1 3 Name2 1 4 Name3 0

  • LWJGL - Continuous key press event without delay

  • How to make xlock use the first key I hit as a part of my password

    - by alesplin
    I just switched from Arch Linux to Ubuntu 10.10. I'm running the Fluxbox window manager, and I use xlockmore to lock my screen with the following key shortcut: 192 :Exec xlock-mode marquee +usefirst -icongeometry 240x240 -message "back in a minute..." The problem I'm having is that xlock is definitely not using my first key as part of my password. Instead, it uses some randomized fade pattern to fade to the password screen. I find this highly annoying, as when I get back to my desk and start entering my password it doesn't register password characters until the fade pattern is complete. I've also tried the following modifications with no difference: 192 :Exec xlock -mode marquee -usefirst -icongeometry 240x240 -message "back in a minute..." 192 :Exec xlock -mode marquee -icongeometry 240x240 -message "back in a minute..." The first example worked flawlessly on Arch. Does Ubuntu have some sort of system default that you can't override on the command-line?

  • Checking whether a specific key was pressed in enchantJS

    - by MxyL
    I am using enchantJS and would like to use the letters and numbers as well as numpad on a keyboard to do different things (eg: hotkeys). From this page http://users.csc.calpoly.edu/~foaad/enchant/guide/playerInput.html By default, enchant.js provides input listeners for six buttons: UP, DOWN, LEFT, RIGHT, A, and B. By default, the directions are bound to the arrow keys. Any of the six buttons may also be bound to any key with an ASCII value. We’ll address that later. So enchant provides the ability to bind keys to different input such as up, down, left, right...but how can I simply check whether the D or X key was pressed, and if so, perform certain actions based on that event?

  • Speed up ssh login using public key down to 0.1sec

    - by BarsMonster
    Hi! I am using Putty to login to my local server, but it takes about 1.5 seconds to login (from the click on 'connect' to working command prompt, most of time is spend on "Authenticating with public key..."). I know many see even slower speeds, but I would like to have not more than 0.1 login time. I already set UseDNS=no and allowed only IPv4 in putty client and reduced key length from 4k down to 1k. Any other suggestions to speed it further?

    I have already read Delete and arrow keys not working and tried what is written there. I have also tried restarting my computer. I have also searched elsewhere for answers, but I haven't found any solution. I am using Ubuntu 12.04, and there were not problems yesterday, but for the last hour, I've had the following problem. When I press the up or the right arrow, nothing happens. When I press the down arrow, it doesn't make anything go down, but something appears in the upper right corner of my screen: http://i.imgur.com/pmnFOCD.png When I press the delete key, nothing gets deleted, but something appears in the upper right corner of my screen: http://i.imgur.com/Wu9czel.png The left arrow still works. Can anybody help me get my three arrow keys and delete key back?

  • Keypress Left is called twice in Update when key is pressed only once

    - by Simran kaur
    I have a piece of code that is changing the position of player when left key is pressed. It is inside of Update() function. I know, Update is called multiple times, but since I have an ifstatement to check if left arrow is pressed, it should update only once. I have tested using print statement that once pressed, it gets called twice. Problem: Position updated twice when key is pressed only once. Below given is the structure of my code: void Update() { if (Input.GetKeyDown (KeyCode.LeftArrow)) { print ("PRESSEEEEEEEEEEEEEEEEEEDDDDDDDDDDDDDD"); } } I looked up on web and what was suggested id this: if (Event.current.type == EventType.KeyDown && Event.current.keyCode == KeyCode.LeftArrow) { print("pressed"); } But, It gives me an error that says: Object reference not set to instance of an object How can I fix this?

  • Adding a small slide when player releases left/right key

    - by Dave
    the aim is for the player object to slow down and stop instead of just stopping dead. The following codes works ok when the player is not jumping, but gets stuck in an object if the player is in the air when they do it. Left Key released event: if hsp = 0 exit; hspeed = -3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } Right key released event: if hsp = 0 exit; hspeed = +3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } and here's the horizontal collision code for interest: if (place_meeting(x+hsp,y,obj_bound)) { while(!place_meeting(x+sign(hsp),y,obj_bound)) { x += sign(hsp); } hsp = 0; } x += hsp; Any help would be much appreciated. Thanks.

  • How can I add missing Fn-key controls?

    - by Alex Ball
    I have a Toshiba NB200 netbook. The majority of the Fn-key controls come through fine and are recognized by my OS (I'm running Kubuntu 12.04/KDE 4.9) but according to the markings on my keyboard there are a few more that xev isn't detecting, i.e. Fn + F9 (touchpad toggle) Fn + 1 (increase screen resolution) Fn + 2 (decrease screen resolution) Fn + Space (zoom) Now, I don't particularly need those last three but I thought it would be quite useful to remap them to, say, Media Previous, Media Next, and Media Play, but I can't do that if the signals aren't getting through. Is there any way for me to persuade the OS to recognize these keystrokes? I've tried using acpi_listen to detect scancodes but it doesn't pick up any of function-related Fn-key strokes (like Audio Mute, which does work by the way).

  • Upstart Script: Detect Shift Key Down At Boot

    - by bambuntu
    I want to create a boot up potential which allows a different upstart/runlevel configurations to load based upon specific key downs at boot (or combos). How do I detect a key down event with an upstart script? I'm offering a bounty. The deal is you must provide a very simple piece of working code to do this. I will immediately check the code and verify that it works. I'm on 10.04 if that helps. Alternative methods to achieve the same result are acceptable, i.e., if grub could somehow show entries that would indicate a type of boot, where that boot would cp appropriate files to /etc/init. So, instead of a keydown solution, it would be a boot menu item solution and the way to get grub to copy upstart scripts to /etc/init. If possible.
