• Android layout issue - table/grid/linear

  - by phpmysqlguy

  I am trying to wrap my head around some basic layout issues in android. Here is what I want as my final goal: As you can see, various fields set up like that. The fields get filled in based on XML data. There could be 1 set of fields, or there could be more. I tried a tablelayout, but couldn't get it set up right even when layout_span for Field 7. It worked ok, but when I tried to change the widths of Field 1 thru 5, the spanned row below it didn't conform to the changes (not like an HTML table would). The fields in each group need to lineup if there are more than one (see red lines in image). Can someone point me in the right direction on how I should approach this? Thanks

• outlook calendar connectivity with java web service

  - by Isisagate

  We currently have a java/jsp online web service that includes it's own custom calendar. I am trying to do some research into the possibility of connecting it to a users outlook. Our basic needs that are most simple is some way to sent the person a meeting request that can be added to their outlook from our service. I know the ideal solution is to sync back and forth but simply being able to import the data from our calendar into someone's outlook would be sufficient. Does anyone have any resources they can point me to that might help with information gathering, or any example/comments?

• Basics of html5 and canvas

  - by René Nyffenegger

  As I browse through different questions here, I see that there are a number of questions tagged with html5 and canvas, so I guess they sort of belong together. Now, I have absolutely no idea about the canvas (which is obviously (?) rendered in html5), but it seems that It could be useful one day in the future. So, in order to be prepared when that day comes, I'd like to know the basics about these things. I found a html snippet that is supposed to render such a canvas, but when opened in my browser (firefox) nothing is displayed. So, I guess I need a special plugin or another browser. My question: what are the absolute basic things I need to know and have in order to create a hello world thingy. Please bear in mind that I am completely new with this and don't need no fancy advanced stuff.

• Circular reference while setting up bidirectional communication line between two remote objects

  - by mphair

  I'm using .Net remoting to set up a bidirectional communication line between two objects. The basic structure is as follows: Instances of RemoteObjectA call methods on StaticObjectA. Instances of RemoteObjectB call methods on StaticObjectB. StaticObjectA needs to be able to call methods provided by RemoteObjectB. StaticObjectB needs to be able to call methods provided by RemoteObjectA. The problem with this setup is the circular reference in RemoteObjectA gets StaticObjectA gets RemoteObjectB gets StaticObjectB gets RemoteObjectA... I implemented an interface IRemoteObjectA and IRemoteObjectB and had the remote objects inheret from their respective interfaces, but then setting up the remoting fails. If the solution to this problem is: "don't use remoting", I can deal with that. Just wanted to make sure I wasn't missing a simple solution.

• JQuery Facebook like Tag feature

  - by Tech

  Hi, Does anyone know of a very basic tag JQuery script? (Facebook like tag feature) All I want to do is when I type @ in a text box for it to search an AJAX search, it then brings back a display name i.e. "Bob Johnson" and an associated Id and stores the Id in a comma delimited list. So an example would be the following .... [TextArea] [Name 1] [Name 2] [Name 3] The thing is it also needs to remove this entry (Id) once the tag gets removed, also it needs to load into a DIV which has a scrollbar so that the list doesn't get to big. If anyone know's how/if this is possible that would be great. Thanks.

• What is a good cms that is postgres compatible, open source and either php or python based?

  - by hackg

  Php or python Use and connect to our existing postgres databases open source / or very low license fees Common features of cms, with admin tools to help manage / moderate community have a large member base on very basic site where members provide us contact info and info about their professional characteristics. About to expand to build new community site (to migrate our member base to) where the users will be able to msg each other, post to forums, blog, share private group discussions, and members will be sent inivitations to earn compensation for their expertise. Profile pages, job postings, and video chat would be plus. Already have a team of admins savvy with web apps to help manage it but our developer resources are limited (3-4 programmers) and looking to save time in development as opposed to building our new site from scratch.

• Is It possible to change dynamically delay on a Scheduled Poller in Camel via JMX?

  - by sebbrousse

  I would like to set/change the delay of a File consumer at runtime through JMX. I am able to change the value of the property but it doesn't seem to be taken into account until I restart the consumer. Example with the camel-archetype-java and its basic file example: Run It Change the delay of the File Consumer by calling the setDelay Operation with the JConsole Delay property of the Consumer is changed but logs show it continues to poll at 500ms by default Stop/Start the consumer New value of delay is used by the consumer Do I need anothers steps or active any configuration to make it work at runtime?

• JAVA bytecode optimization

  - by Idob

  This is a basic question. I have code which shouldn't run on metadata beans. All metadata beans are located under metadata package. Now, I use reflection API to find out whether a class is located in the the metadata package. if (newEntity.getClass().getPackage().getName().contains("metadata")) I use this If in several places within this code. The question is: Should I do this once with: boolean isMetadata = false if (newEntity.getClass().getPackage().getName().contains("metadata")) { isMetadata = true; } C++ makes optimizations and knows that this code was already called and it won't call it again. Does JAVA makes optimization? I know reflection API is a beat heavy and I prefer not to lose expensive runtime.

• vb express / visual studio - is it possible to run / debug one form only in a multi form application

  - by Luay

  hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

• How to launch an external application on BN_CLICKED?

  - by Alienexist

  I'm fairly new to Windows programming. I'm doing a simple launcher app for WinCE using VC++ (not MFC). So far I've created the basic interface and buttons and stuff. I just wanted to know the best way to launch an external application when the user clicks the button (on BN_CLICKED). I found some methods such as ShellExecute, CreateProcess and others. But I couldn't get it to work (yet?). Any suitable reference or simple example on this?

• Order of execution and style of coding in Python

  - by Jason

  Hi guys. I am new to Python so please don't flame me if the question is too basic :) I have read that Python is executed from top - to - bottom. If this is the case, why do programs go like this: def func2(): def func1(): #call func2() def func() #call func1() if __name__ == '__main__': call func() So from what I have seen, the main function goes at last and the other functions are stacked on top of it. Am I wrong in saying this? If no, why isn't the main function or the function definitions written from top to bottom?

• Passing a pointer to an array to glGenBuffers

  - by Josh Elsasser

  I'm currently passing an array to a function, then attempting to use glGenBuffers with the array that is passed to the function. I can't figure out a way to get glGenBuffers to work with the array that I've passed. I have a decent grasp of the basics of pointers, but this is beyond me. This is basically how the render code works. It's a bit more complex, (colours using the same array idea, also not working) but the basic idea is as follows: void drawFoo(const GLfloat *renderArray, GLuint verticeBuffer) { glBindBuffer(GL_ARRAY_BUFFER, verticeBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(verticeBuffer)*sizeof(GLfloat), verticeBuffer, GL_STATIC_DRAW); glVertexPointer(2, GL_FLOAT, 0, 0); glEnableClientState(GL_VERTEX_BUFFER); glDrawArrays(GL_TRIANGLE_FAN, 0, 45); glDisableClientState(GL_VERTEX_BUFFEr); } Thanks in advance for the help

• How to model file system operations with REST?

  - by massive

  There are obvious counterparts for some of file systems' basic operations (eg. ls and rm), but how would you implement not straightforwardly RESTful actions such as cp or mv? As answers to the question REST services - exposing non-data “actions” suggest, the preferred way of implementing cp would include GETting the resource, DELETing it and PUTting it back again with a new name. But what if I would need to do it efficiently? For instance, if the resource's size would be huge? How would I eliminate the superfluous transmission of resource's payload to client and back to the originating server? Here is an illustration. I have a resource: /videos/my_videos/2-gigabyte-video.avi and I want copy it into a new resource: /videos/johns_videos/copied-2-gigabyte-video.avi How would I implement the copy, move or other file system actions the RESTful way? Or is there even a proper way? Am I doing it all wrong?

• Query SQL Server Database from native iOS Application

  - by mbm30075

  I am working on an in-house, iOS app that will need read-only access to a SQL Server with multiple databases. I know the stock answer here is "write some web services", but I'd like a solution that is self-contained. Is there any way to directly connect to a SQL Server database from an iOS application? I'm thinking something like a basic ODBC connection. I've seen a lot of users asking this question, but very few answers other than "write a web service." Is that really the only way?

• Looking for a free CMS which allows content injection

  - by ChocolateSheep

  Hi all, I was wondering if anyone could tell me of a free CMS that will allow me to change the basic content (text, image etc etc) of a website, without forcing it's own templates or designs. This is the scenario; I have already designed my website, already implemented it, and I just need a way for the actual User to edit the contents of the pages. I've looked into Drupal and Joomla, and the hosted ones such as CushyCMS (I liked the way this worked) and SimpleCMS, however I am a bit wary of hosted CMS systems... Any ideas??

• Lua not producing table of functions (IO API)

  - by ArtOfCode

  I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

• What do I need to learn to make a website that can make a text file?

  - by lala

  I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

• How secure is encryption?

  - by Stomped

  Let me preface this by saying I know nothing about encryption. I understand the basic concept of public key / private key encryption but I don't how easily it can be broken, if at all. If one were to believe the movies, encrypted data can be broken by a teenager with a decent computer in a few hours. I have a client who wants credit card information sent via email - encrypted of course, but I'm still not feeling terribly good about the idea. I feel it would be safer to store the info on the VPS, but even then its an unmanaged server and there's nobody watching it who knows much about security. So can anyone tell me if there's a safe way to store and/or send this data out? Thanks

• About a Class Object

  - by Chicko Bueno

  I have a very basic question about a class object. After the class has been created, we need to create a class object. At this point, I'm a bit confused to make either *object or object. Example: CClass object CClass *object What is the difference both of them? And to access class function i need to use dot '.' and arrow '->'. I know dot and arrow used to access class function, but what is the significant meaning for both dot and arrow?

• Can I learn the iPhone SDK and complete an app by September?

  - by Kuro

  Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

• Database Optimization techniques for amateurs.

  - by Zombies

  Can we get a list of basic optimization techniques going (anything from modeling to querying, creating indexes, views to query optimization). It would be nice to have a list of these, one technique per answer. As a hobbyist I would find this to be very useful, thanks. And for the sake of not being too vague, let's say we are using a maintstream DB such as MySQL or Oracle, and that the DB will contain 500,000-1m or so records across ~10 tables, some with foreign key contraints, all using the most typical storage engines (eg: InnoDB for MySQL). And of course, the basics such as PKs are defined as well as FK contraints.

• merging 3 source versioned trees into 1

  - by user309779

  This is probably an easy question... I have 4 source versions of the same software in 4 different directories. I have just started using git for version control. To date, I have just been snapping a desperate copy rolling forward. I want to merge all versions (1.0.0.1, 1.0.0.2, 1.0.0.3, 1.0.1.0) together so that I will have a reference history. Opposed to just starting out with 1.0.1.0 as the initial version. I want to get this sort of thing right form the start. Can someone outline the basic steps to accomplish this? Thanks much, XO

• How do I check that an entity is unreferenced in JPA?

  - by Martin

  I have the following model @Entity class Element { @Id int id; @Version int version; @ManyToOne Type type; } @Entity class Type { @Id int id; @Version int version; @OneToMany(mappedBy="type") Collection<Element> elements; @Basic(optional=false) boolean disabled; } and would like to allow Type.disabled = true only if Type.elements is empty. Is there a way to do it atomically? I would like to prevent an insertion of an Element in a transaction while the corresponding Type is being disabled by an other transaction.
