  • Oracle Social Network Developer Challenge Winners

    - by kellsey.ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. Now that OpenWorld 2012 has wrapped, I have time to tell you all about what happened. Maybe you recall that Noel (@noelportugal) and I were running a modified hackathon during the show, the Oracle Social Network Developer Challenge. Without further ado, congratulations to Dimitri Gielis (@dgielis) and Martin Giffy D’Souza (@martindsouza) on their winning entry, an integration between Oracle APEX and Oracle Social Network that integrates feedback and bug submission with Oracle Social Network Conversations, allowing developers, end-users and project leaders to view and discuss the feedback on their APEX applications from within Oracle Social Network. Update: Bob Rhubart of OTN (@brhubart) interviewed Dimitri and Martin right after their big win. Money quote from Dimitri when asked what he’d buy with the $500 in Amazon gift cards, “Oracle Social Network.” Nice one. In their own words: In the developers perspective it’s important to get feedback soon, so after a first iteration and end-users start to test, they can give feedback of the application. Previously it stopped there, and it was up to the developer to communicate further with email, phone etc. With OSN every feedback and communication gets logged and other people can see the discussion immediately as well. For the end users perspective he can now communicate in a more efficient way to not only the developers, but also between themselves. Maybe many end-users (in different locations) would like to change some behaviour, by using OSN they can see the entry somebody put in with a screenshot and they can just start to chat about it. Some key technical end users can have lighten the tasks of the development team by looking at the feedback first and start to communicate with their peers. For the project manager he has now the ability to really see what communication has taken place in certain areas and can make decisions on that. Later, if things come up again, he can always go back in OSN and see what was said at that moment in time. Integrating OSN in the APEX applications enhances the user experience, makes the lives of the developers easier and gives a better overview to project managers. Incidentally, you may already know Dimitri and Martin, since both are Oracle Ace Directors. I ran into Martin at the Ace Director briefings Friday before the conference started, and at that point, he wasn’t sure he’d have time to enter the Challenge. After some coaxing, he and Dimitri agreed to give it a go and banged out their entry on Tuesday night, or more accurately, very early Wednesday morning, the day of the Challenge judging. I think they said it took them about four hours of hardcore coding to get it done, very much like a traditional hackathon, which is essentially a code sprint from idea to finished product. Here are some screenshots of the workflow they built. #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } I love this idea, i.e. closing the loop between web developers and users, a very common pain point, and so did our judges. Speaking of, special thanks to our panel of three judges: Reggie Bradford (@reggiebradford), serial entrepreneur, founder of Vitrue and SVP of Cloud Product Development at Oracle Robert Hipps (@roberthipps), VP of Development for Oracle Social Network and my former boss Roland Smart (@rsmartx), VP of Social Marketing and the brains behind the Oracle Social Developer Community Finally, thanks to everyone who made this possible, including: The three other teams from HarQen (@harqen), TEAM Informatics (@teaminformatics) and Fishbowl Solutions (@fishbowle20) featuring Friend of the ‘Lab John Sim (@jrsim_uix), who finished and presented entries. I’ll be posting the details of their work this week. The one guy who finished an entry, but couldn’t make the judging, Bex Huff (@bex). Bex rallied from a hospitalization due to an allergic reaction during the show; he’s fine, don’t worry. I’ll post details of his work next week, too. The 40-plus people who registered to compete in the Challenge. Noel for all his hard work, sample code, and flying monkey target, more on that to come. The Oracle Social Network development team for supporting this event. Everyone in legal and the beta program office for their help. And finally, the Oracle Technology Network (@oracletechnet) for hosting the event and providing countless hours of operational and moral support. Sorry if I’ve missed some people, since this was a huge team effort. This event was a big success, and we plan to do similar events in the future. Stay tuned to this channel for more.

  • Why are my "tel:" links not working

    - by Griffo
    I have a tableView which has cells with phone numbers. The app is not dialing the numbers though. See the code below - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section == 2) { UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath]; NSString *numberToDial = [NSString stringWithFormat:@"tel:%@", selectedCell.detailTextLabel.text]; NSLog(@"%@",numberToDial); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:numberToDial]]; } } Console ouput: 2010-03-08 01:32:30.830 AIB[1217:207] tel:01 8350098 As you can see, the number goes to the console, but doesn't get dialled. The weird thing is, if I change the last statement to this: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:171"]]; the phone dials the number 171 without any issue

  • Writing to a new line of a file in Objective-C

    - by Kulpreet
    For some strange reason, the \n and \r escape sequences do not seem to be working in my code. I want to write each NSString on a new line of the file, but it just appends it the last string on one line. Here's the code: for (Entry *entry in self.entries) { NSString *path = @"/Users/me/File.txt"; NSString *string = (@"%@\r\n", [entry thisEntry]); NSFileHandle *fh = [NSFileHandle fileHandleForWritingAtPath:path]; [fh seekToEndOfFile]; [fh writeData:[string dataUsingEncoding:NSUnicodeStringEncoding]]; [fh closeFile]; } Am I doing something wrong? Forgive me as I am new to Objective-C.

  • InvalidCastException when creating an instance using assembly.CreateInstance

    - by Yossi Dahan
    I'm looking for an explanation for the following - I have an assembly I'm loading using Assembly assembly = Assembly.LoadFrom(filename); I then loop on all the types in the assembly, and wish to try and find out if a type implements a particular interface and if so I want an instance of that type, I've tried several things which did not work, but when I fell back to the most basic (and probably inefficient) way, I realised there's something more fundamental I don't understand - foreach (Type t in assembly.GetTypes()) { foreach (Type i in t.GetInterfaces()) { if (i.FullName == pluginInterfaceType.FullName) { object o = assembly.CreateInstance(t.ToString()); IInterface plugin = (IInterface)o; That last line causes an InvalidCastException, despite the fact that the type created definitely implements that interface. Further more - if I use Activator.CreateInstance instead of Assembly.CreateInstance (which I don't want to do), casting to the interface works just fine.

  • Can I use the TFS Object Model to interact with TFS via F#?

    - by Russell
    I am looking for some quick ways to do some (more) complex queries across who has what checked out and things like that (eg. which files have 1 person checked out). I have been learning F# over the last year or so and saw the potential to use both the functional aspects of F# to quickly create some useful and more complex TFS commands. I was wondering if anyone else has done this, or have any ideas on how I would go about doing this. PS: I am using TFS 2005. Thanks Russell

  • Jquery.form plugin and jquery.validation and it's submitHandler not working correctly... please help

    - by Matthew
    Hello guys, I was hoping someone can shed some light on what might be occurring on my page. Okay what I currently have on my page is a simple form that collects first name, last name, city, state and email. Once submitted it will hit a PHP page that updates our DB and echo's back to the designted div with a class of .response. I am using jquery.validation and placing that dynamic function within the submitHandler like so: submitHandler: function(form) { $(form).ajaxSubmit({ target: '.response', // target element(s) to be updated with server response resetForm: true, success: function() { $('#commentform').hide(); $('.response').show(); } }); So what I am getting is a div that is not being populated with the echo from my php file in FF and in IE I am getting the message of thank you but the page is taking me to the update.php script in which I have the form action pointing to. I am not sure what I am missing... Thanks, Matt

  • PHP/MySQL database connection priority?

    - by Josh
    Hello, I have a production database where usage statistics for a service we're working on. I use php to periodically roll up different resolutions (day, week, month, year) of interesting statistics in buckets dictated by the resolution. The php application I've written "completes" its data when its run, such that it will calculate all the rolled-up statistics for the resolutions and periods since it was last run. This is useful if we want to turn this off to debug database performance issues, because I can turn it back on and have it complete its data set. The problem I have, is the calculations are fairly intensive and drive the QPS of the production database server up. Is there a way to set a "priority" on a particular database connection so that it will only use "off-cycles" to do these calculations? Maybe a proper response would be to replicate the tables I'm working on into a different stats database, but, unfortunately I don't have the resources in place to attempt such a thing (yet). Thanks in advance for any help, Josh

  • Firefox session cookies

    - by meandmycode
    Generally speaking, when given a cookie that has no expiration period, modern browsers will consider this cookie to be a 'session cookie', they will remove the cookie at the end of the browsing session (generally when the browser instance closes). IE, Opera, Safari and Chrome all support this behavior. However firefox (3.0.9 latest proper release) appears not to follow this rule, from what I can tell it doesn't expire the cookies when the browser is closed, or when the user logs off or restarts the OS.. So, why does firefox refer to these as session cookies, when they last aparently indefinitely? Does anyone know how Firefox handles session cookie expiration?

  • Linux HA / cluster: what are the differences between Pacemaker, Heartbeat, Corosync, wackamole?

    - by Continuation
    Can you help me understand Linux HA? Pacemaker, Heartbeat, Corosync seem to be part of a whole HA stack, but how do they fit together? How does wackamole differ from Pacemaker/Heartbeat/Corosync? I've seen opinions that wackamole is better than Heartbeat because it's peer-based. Is that valid? The last release of wackamole was 2.5 years ago. Is it still being maintained or active? What would you recommend for HA setup for web/application/database servers?

  • How can let Qt Graphics View Framework support custom layers

    - by jnblue
    Qt's graphics view frameworks is very powerful, but I have not found a way to support custom layers. In Qt, there is a QGraphicsScene::ItemLayer,but QGraphicsScene renders all items are in this layer. I want manage the items with several layers, Just like Illustrator and CorelDraw. all the item only in the current layer will receive the event, be selected or get the key focus etc.. Other layers(not current layer) will not receive all scene event. The most reasons of using layers is I could catalogue a large number of items more clearly.And without needing transfer events to all the layers' items ,I think the graphics frameworks will be more efficient. The last question, does QGraphicsView support rendering server stacked graphics scenes at the same time? If support, I think the "custom layers" can be solved in this way. Thanks very much!

  • Weird y offset when using custom frag shader (Cocos2d-x)

    - by Mister Guacamole
    I'm trying to mask a sprite so I wrote a simple fragment shader that renders only the pixels that are not hidden under another texture (the mask). The problem is that it seems my texture has its y-coordinate offset after passing through the shader. This is the init method of the sprite (GroundZone) I want to mask: bool GroundZone::initWithSize(Size size) { // [...] // Setup the mask of the sprite m_mask = RenderTexture::create(textureWidth, textureHeight); m_mask->retain(); m_mask->setKeepMatrix(true); Texture2D *maskTexture = m_mask->getSprite()->getTexture(); maskTexture->setAliasTexParameters(); // Disable linear interpolation on the mask // Load the custom frag shader with a default vert shader as the sprite’s program FileUtils *fileUtils = FileUtils::getInstance(); string vertexSource = ccPositionTextureA8Color_vert; string fragmentSource = fileUtils->getStringFromFile( fileUtils->fullPathForFilename("CustomShader_AlphaMask_frag.fsh")); GLProgram *shader = new GLProgram; shader->initWithByteArrays(vertexSource.c_str(), fragmentSource.c_str()); shader->bindAttribLocation(GLProgram::ATTRIBUTE_NAME_POSITION, GLProgram::VERTEX_ATTRIB_POSITION); shader->bindAttribLocation(GLProgram::ATTRIBUTE_NAME_TEX_COORD, GLProgram::VERTEX_ATTRIB_TEX_COORDS); shader->link(); CHECK_GL_ERROR_DEBUG(); shader->updateUniforms(); CHECK_GL_ERROR_DEBUG(); int maskTexUniformLoc = shader->getUniformLocationForName("u_alphaMaskTexture"); shader->setUniformLocationWith1i(maskTexUniformLoc, 1); this->setShaderProgram(shader); shader->release(); // [...] } These are the custom drawing methods for actually drawing the mask over the sprite: You need to know that m_mask is modified externally by another class, the onDraw() method only render it. void GroundZone::draw(Renderer *renderer, const kmMat4 &transform, bool transformUpdated) { m_renderCommand.init(_globalZOrder); m_renderCommand.func = CC_CALLBACK_0(GroundZone::onDraw, this, transform, transformUpdated); renderer->addCommand(&m_renderCommand); Sprite::draw(renderer, transform, transformUpdated); } void GroundZone::onDraw(const kmMat4 &transform, bool transformUpdated) { GLProgram *shader = this->getShaderProgram(); shader->use(); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, m_mask->getSprite()->getTexture()->getName()); glActiveTexture(GL_TEXTURE0); } Below is the method (located in another class, GroundLayer) that modify the mask by drawing a line from point start to point end. Both points are in Cocos2d coordinates (Point (0,0) is down-left). void GroundLayer::drawTunnel(Point start, Point end) { // To dig a line, we need first to get the texture of the zone we will be digging into. Then we get the // relative position of the start and end point in the zone's node space. Finally we use the custom shader to // draw a mask over the existing texture. for (auto it = _children.begin(); it != _children.end(); it++) { GroundZone *zone = static_cast<GroundZone *>(*it); Point nodeStart = zone->convertToNodeSpace(start); Point nodeEnd = zone->convertToNodeSpace(end); // Now that we have our two points converted to node space, it's easy to draw a mask that contains a line // going from the start point to the end point and that is then applied over the current texture. Size groundZoneSize = zone->getContentSize(); RenderTexture *rt = zone->getMask(); rt->begin(); { // Draw a line going from start and going to end in the texture, the line will act as a mask over the // existing texture DrawNode *line = DrawNode::create(); line->retain(); line->drawSegment(nodeStart, nodeEnd, 20, Color4F::RED); line->visit(); } rt->end(); } } Finally, here's the custom shader I wrote. #ifdef GL_ES precision mediump float; #endif varying vec2 v_texCoord; uniform sampler2D u_texture; uniform sampler2D u_alphaMaskTexture; void main() { float maskAlpha = texture2D(u_alphaMaskTexture, v_texCoord).a; float texAlpha = texture2D(u_texture, v_texCoord).a; float blendAlpha = (1.0 - maskAlpha) * texAlpha; // Show only where mask is invisible vec3 texColor = texture2D(u_texture, v_texCoord).rgb; gl_FragColor = vec4(texColor, blendAlpha); return; } I got a problem with the y coordinates. Indeed, it seems that once it has passed through my custom shader, the sprite's texture is not at the right place: Without custom shader (the sprite is the brown thing): With custom shader: What's going on here? Thanks :) EDIT It looks like after passing through the shader when I set the position of the sprite I set it in points, with (0,0) being in the top-right. Indeed, when I do sprite->setPosition(320, 480), the sprite is perfectly placed at the top of the screen.

  • ViewPager cycle between views?

    - by Erdem Azakli

  • How to read formatted input in python?

    - by eSKay
    I want to read from stdin five numbers entered as follows: 3, 4, 5, 1, 8 into seperate variables a,b,c,d & e. How do I do this in python? I tried this: import string a=input() b=a.split(', ') for two integers, but it does not work. I get: Traceback (most recent call last): File "C:\Users\Desktop\comb.py", line 3, in <module> b=a.split(', ') AttributeError: 'tuple' object has no attribute 'split' How to do this? and suppose I have not a fixed but a variable number n integers. Then?

  • How do you prevent file confusion if version-control keywords are forbidden?

    - by Thomas L Holaday
    At least two brilliant programmers, Linus Torvalds and Guido von Rossum, disparage the practice of putting keywords into a file that expand to show the version number, last author, etc. I know how keyword differences clutter up diffs. One of the reasons I like SlickEdit's DiffZilla is because it can be set to skip leading comments. However, I have vivid memories of team-programming where we had four versions of a file (two different releases, a customer one-off, and the development version) all open for patching at the same time, and was quite helpful to verify with a glance that each time we navigated to an included header we got the proper one, and each time we pasted code the source and destination were what we expected. There is also the where-did-this-file-come-from problem that arises when a hasty developer copies a file from one place to another using the file system, rather than checking it out of the repository using the tool; or, more defensibly, when files under control in locations A, B, and C need to be marshalled (with cherry-picking) into a distribution location D. In places where VCS keywords are banned, how do you cope?

  • Effective file permissions tool's api in windows

    - by apoorv020
    Starting from Windows Server 2003, Windows included a new tool which calculates the effective permissions for a user (basically it resolves all groups access and takes care of all "deny" permissions as well). An example in point is that a user A belongs to groups B and C. B has been denied read permissions on a file F, while C has been allowed read and write permissions on the file and I want to calculate the effective permissions user A has on file F. This tool is available on Windows Server 2003,Vista,7 and Server 2008 by right clicking on a file and going to properties - security - advanced - effective permissions. What I need is an API in C# which does the same job. The most common FILE API returns access rules (class FileAccessRules), but there seems to be no direct way to calculate effective permissions from these set of access rules. Note: I do not want to process effective permissions in the code if at all possible, but am ready to do so as a last resort.

  • How get file names using OpenFileDialog in .NET (1000+ file multiselect)

    - by Cole
    Maybe some of you have come across this before.... I am opening files for parsing. I'm using OpenFileDialog, of course, but i'm limited to a buffer of 2048 on the .FileNames string. Thus, I can only select a few hundred files. This is OK for most cases. However, fore example, I have in one case 1400 files to open. Do you know a way to do this with the open file dialog. I just want the string array of .FileNames, I pass that to parser class. I was also thinking of offering a FolderBrowserDialog option and then I'd use some other method to just loop through all the files in a directory, like the DirectoryInfo class. I'd do this as a last resort if I can't have an all in one solution.

  • Performing a clean database creation using msbuild

    - by Robert May
    So I’m taking a break from writing about other Agile stuff for a post. :)  I’m still going to get back to the other subjects, but this is fun too. Something I’ve done quite a bit of is MSBuild and CI work.  I’m experimenting with ways to improve what I’ve done in the past, particularly around database CI. Today, I developed a mechanism for starting from scratch with your database.  By scratch, I mean blowing away the existing database and creating it again from a single command line call.  I’m a firm believer that developers should be able to get to a known clean state at the database level with a single command and that they should be operating off of their own isolated database to improve productivity.  These scripts will help that. Here’s how I did it.  First, we have to disconnect users.  I did so using the help of a script from sql server central.  Note that I’m using sqlcmd variable replacement. -- kills all the users in a particular database -- dlhatheway/3M, 11-Jun-2000 declare @arg_dbname sysname declare @a_spid smallint declare @msg varchar(255) declare @a_dbid int set @arg_dbname = '$(DatabaseName)' select @a_dbid = sdb.dbid from master..sysdatabases sdb where sdb.name = @arg_dbname declare db_users insensitive cursor for select sp.spid from master..sysprocesses sp where sp.dbid = @a_dbid open db_users fetch next from db_users into @a_spid while @@fetch_status = 0 begin select @msg = 'kill '+convert(char(5),@a_spid) print @msg execute (@msg) fetch next from db_users into @a_spid end close db_users deallocate db_users GO Once all users are booted from the database, we can commence with recreating the database.  I generated the script that is used to create a database from SQL Server management studio, so I’m only going to show the bits that weren’t generated that are important.  There are a bunch of Alter Database statements that aren’t shown. First, I had to find the default location of the database files in the install, since they can be in many different locations.  I used Method 1 from a technet blog and then modified it a bit to do what I needed to do.  I ended up using dynamic SQL because for the life of me, I couldn’t get the “Filename” property to not return an error when I used anything besides a string.  I’m dropping the database first, if it exists.  Here’s the code:   IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = N'$(DatabaseName)') BEGIN drop database $(DatabaseName) END; go IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; -- Create temp database. Because no options are given, the default data and --- log path locations are used CREATE DATABASE zzTempDBForDefaultPath; DECLARE @Default_Data_Path VARCHAR(512), @Default_Log_Path VARCHAR(512); --Get the default data path SELECT @Default_Data_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 0); --Get the default Log path SELECT @Default_Log_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 1); --Clean up. IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; DECLARE @SQL nvarchar(max) SET @SQL= 'CREATE DATABASE $(DatabaseName) ON PRIMARY ( NAME = N''$(DatabaseName)'', FILENAME = N''' + @Default_Data_Path + N'$(DatabaseName)' + '.mdf' + ''', SIZE = 2048KB , FILEGROWTH = 1024KB ) LOG ON ( NAME = N''$(DatabaseName)Log'', FILENAME = N''' + @Default_Log_Path + N'$(DatabaseName)' + '.ldf' + ''', SIZE = 1024KB , FILEGROWTH = 10%) ' exec (@SQL) GO And with that, your database is created.  You can run these scripts on any server and on any database name.  To do that, I created an MSBuild script that looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <PropertyGroup> <DatabaseName>MyDatabase</DatabaseName> <Server>localhost</Server> <SqlCmd>sqlcmd -v DatabaseName=$(DatabaseName) -S $(Server) -i </SqlCmd> <ScriptDirectory>.\Scripts</ScriptDirectory> </PropertyGroup> <Target Name ="Rebuild"> <ItemGroup> <ScriptFiles Include="$(ScriptDirectory)\*.sql"/> </ItemGroup> <Exec Command="$(SqlCmd) &quot;%(ScriptFiles.Identity)&quot;" ContinueOnError="false"/> </Target> </Project> Note that the Scripts directory is underneath the directory where I’m running the msbuild command and is relative to that directory.  Note also that the target is using batching to run each script in the scripts subdirectory, one after the other.  Each script is passed to the sqlcmd command line execution using the .Identity property on the itemgroup that is created.  This target file is saved in the file “Database.target”. To make this work, you’ll need msbuild in your path, and then run the following command: msbuild database.target /target:Rebuild Once you’ve got your virgin database setup, you’d then need to use a tool like dbdeploy.net to determine that it was a virgin database, build a change script based on the change scripts, and then you’d want another sqlcmd call to update the database with the appropriate scripts.  I’m doing that next, so I’ll post a blog update when I’ve got it working.

  • Is there a way to make PHP progressively output as the script executes?

    - by Iain Fraser
    So I'm writing a disposable script for my own personal single use and I want to be able see how the process is going. Basically I'm processing a couple of thousand media releases and sending them to our new CMS. So I don't hammer the CMS, I'm making the script sleep for a couple of seconds after every 5 requests. I would like - as the script is executing - to be able to see my echos telling me the script is going to sleep or that the last transaction with the webservice was successful. Is this possible in PHP? Thanks for your help! Iain

  • masked input: I can't get the simplest completion to work

    - by Karl Messner
    Trying to use Josh Bush's masked input plugin. I want to shift focus and do other things once the person puts their cell phone in. I mask to a phone shape. When I hit the last letter, I want it to trigger a javascript function. Right now that function just alerts hi. But I can't get it to work: function jump(){ alert('hi'); } $(document).ready(function(){ $("#cellphone").focus(); jQuery(function($){ $("#product").mask("(999) 999-9999",{completed:function(){jump();}}); }); });

  • creating a custom centered cyclic horizontal manager

    - by Hezi
    Trying to create a custom cyclical horizontal manager which will work as follows. It will control several field buttons where the buttons will always be positioned so that the focused button will be in the middle of the screen. As it is a cyclical manager once the focus moves to the right or left button, it will move to the center of the screen and all the buttons will move accordingly (and the last button will become the first to give it an cyclic and endless list feeling) Any idea how to address this? I tried doing this by implementing a custom manager which aligns the buttons according to the required layout. Each time moveFocus() is called I remove all fields (deleteAll() ) and add them again in the right order. Unfortunately this does not work.

  • Common and useful Graph functions?

    - by Nazgulled
    Hi, I'm implementing a simple Graph library for my uni project and since this is the first time I'm dealing with graphs, I would like to know which functions you guys consider to be most common and useful for Graph implementations... So far, I have this: graphInitialize() graphInsertVertex() graphRemoveVertex() graphGetVertex() graphGetVertexValue() (not implemented yet, not sure if I'll need it) graphInsertEdge() graphRemoveEdge() graphLinkVertices() (this calls graphInsertEdge twice for bidirectional graph) graphUnlinkVertices() (this calls graphRemoveEdge twice for bidirectional graph) graphDestroy() I know I'm missing a function do determine the shortest path, but I'm leaving that for last... Do you think I'm missing any common/useful function?

  • So how I can control the page contents loading sequence in dojo

    - by David Zhao
    Hi there, I'm using dojo for our UI's, and would like to load certain part of page contents in sequence. For example, for a certain stock, I'd like to load stock general information, such as ticker, company name, key stats, etc. and a grid with the last 30 days open/close prices. Different contents will be fetched from the server separately. Now, I'd like first load the grid so the user can have something to look at, then, say, start loading of key stats which is a large data set takes longer time to load. How do I do this. I tried: dojo.addOnLoad(function() { startGrid(); //mock grid startup function which works fine getKeyStats(); //mock key stat getter function also works fine }); But dojo is loading getKeyStats(), then startGrid() here for some reason, and sequence doesn't seem be matter here. So how I can control the loading sequence at will? Thanks in advance! David

  • Three coworkers Riddle Problem

    - by John S
    This isn't homework, I've got a solution, however it doesn't protect against cheaters. Three coworkers would like to know their average salary. However, they are self-conscious and don't want to tell each other their own salaries, for fear of either being ridiculed or getting their houses robbed. How can they find their average salary, without disclosing their own salaries? Now, a solution that requires the last person to tell the group the sum isn't allowed because that person could cheat.
