• Flex - Is there a way to change the "Channel Disconnected" error message?

  - by Travesty3

  I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message they don't understand. Anyone know of a way for me to change this error message? BTW I'm pretty much a noob when it comes to Flash programming so please be descriptive. Using Flash Builder 4 Beta 2.

• Joining on a common table, how do you get a FULL OUTER JOIN to expand on another table?

  - by stimpy77

  I've scoured StackOverflow and Google for an answer to this problem. I'm trying to create a Microsot SQL Server 2008 view. Not a stored procedure. Not a function. Just a query (i.e. a view). I have three tables. The first table defines a common key, let's say "CompanyID". The other two tables have a sometimes-common field, let's say "EmployeeName". I want a single table result that, when my WHERE clause says "WHERE CompanyID = 12" looks like this: CompanyID | TableA | TableB 12 | John Doe | John Doe 12 | Betty Sue | NULL 12 | NULL | Billy Bob I've tried a FULL OUTER JOIN that looks like this: SELECT Company.CompanyID, TableA.EmployeeName, TableB.EmployeeName FROM Company FULL OUTER JOIN TableA ON Company.CompanyID = TableA.CompanyID FULL OUTER JOIN TableB ON Company.CompanyID = TableB.CompanyID AND (TableA.EmployeeName IS NULL OR TableB.EmployeeName IS NULL OR TableB.EmployeeName = TableA.EmployeeName) I'm only getting the NULL from one matched table, I'm not getting the expansion for the other table. In the above sample, I'm basically only getting the first and third rows and not the second. Can someone help me create this query and show me how this is done correctly? BTW I already have a stored procedure that looks very clean and populates an in-memory table, but that isn't what I want. Thanks.

• UISearchDisplayController changing row height

  - by tewha

  I've set my UITableView row height to in Interface Builder to 54.0. I have a UISearchDisplayController on that view. When the user taps the search bar in it, the table resizes properly. However, when they start typing (and actually doing the search) the row height decreases. It stays wrong until the search taps Cancel. I could find no documentation on this behavior on Apple's site. I've tried setting the row height in UISearchDisplayDelegate delegate calls. This might be the right approach, but I don't know the details and couldn't get it ti work. I've also tried implementing -- (CGFloat)tableView:(UITableView *)tableView -heightForRowAtIndexPath:(NSIndexPath *)indexPath;. This worked, but I have thousands of entries in this list and can't take the performance hit. What's the right way to fix this?

• Why is PHP not allowing comparison?

  - by dcp3450

  I'm using PHP to read if an entry in my table on the database is set to "yes" or "no" and auto check the radio button that corresponds: <?php include 'file.php'; $query = "SELECT * FROM TABLE"; $runquery = odbc_exec($connect,$query); $status= odbc_result($runquery,"status"); odbc_close($file); ?> <form> <div class="formContainer"> <fieldset> <legend>Campus Alert<span class="tooltip">Turn campus alert on and off.</span></legend> <?php echo $status; ?> Yes <input type="radio" name="alertStatus" id="alertStatus" value="yes" <?php if($status== "yes") echo "checked";?>> No <input type="radio" name="alertStatus" id="alertStatus" value="no" <?php if($status== "no") echo "checked";?>> </fieldset> </div> the is for debugging so I can make sure what the database says and the form's reaction is correct. It prints "yes" (no quotes). However, the if statement will not respond. Any idea why it's doing this?

• Need to parse HTML document for links-- use a library like html5lib or something else?

  - by Luinithil

  I'm a very newbie webpage builder, currently working on creating a website that needs to change link colours according to the destination page. The links will be sorted into different classes (e.g. good, bad, neutral) by certain user input criteria-- e.g. links with content the user would find of interest is colored blue, stuff that the user (presumably) doesn't want to see is colored as normal text, etc. I reckon I need a way to parse the webpage for links to the content (stored in MySQL database), change the colors for all the links on the page (so I need to be able to change the link classes in the HTML as well) before outputting the adapted page to the user. I read that regex is not a good way to find those links-- so should I use a library, and if so, is html5lib good for what I'm doing?

• SQL SERVER 2008 JOIN hints

  - by Nai

  Hi all, Recently, I was trying to optimise this query UPDATE Analytics SET UserID = x.UserID FROM Analytics z INNER JOIN UserDetail x ON x.UserGUID = z.UserGUID Estimated execution plan show 57% on the Table Update and 40% on a Hash Match (Aggregate). I did some snooping around and came across the topic of JOIN hints. So I added a LOOP hint to my inner join and WA-ZHAM! The new execution plan shows 38% on the Table Update and 58% on an Index Seek. So I was about to start applying LOOP hints to all my queries until prudence got the better of me. After some googling, I realised that JOIN hints are not very well covered in BOL. Therefore... Can someone please tell me why applying LOOP hints to all my queries is a bad idea. I read somewhere that a LOOP JOIN is default JOIN method for query optimiser but couldn't verify the validity of the statement? When are JOIN hints used? When the sh*t hits the fan and ghost busters ain't in town? What's the difference between LOOP, HASH and MERGE hints? BOL states that MERGE seems to be the slowest but what is the application of each hint? Thanks for your time and help people! I'm running SQL Server 2008 BTW. The statistics mentioned above are ESTIMATED execution plans.

• SQLite self-join performance

  - by Derk

  What I essentially want, is to retreive all features and values of products which have a particular feature and value. For example: I want to know all available hard drive sizes of products that have an Intel processor. I have three tables: product_to_value (product_id, feature_id, value_id) features (id, value) // for example Processor family, Storage size, etc. values (id, value) // for example Intel, 60GB, etc The simplified query I have now: SELECT features.name, featurevalues.name, featurevalues.value FROM products, products as prod2, features, features as feat2, values, values as val2 WHERE products.feature = features.id AND products.value = values.id AND products.product = prod2.product AND prod2.feature_id = feat2.id AND prod2.value_id = val2.id AND features.id = ? AND feat2.id = ? All columns have an index. I am using SQLite. The problem is that it's very slow (70ms per query, without the self-join it's <1ms). Is there a smarter way to fetch data like this? Or is this too much to ask from SQLite? I personally think I am simply overlooking something, as I am quite new to SQLite.

• move_uploaded_file() error

  - by James R.

  I have a website on free hosting - 000webhost.com and it allows you to upload images. However, when I try to upload an image, I get these errors: Warning: move_uploaded_file(images/SmallSmileyFace.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in /home/a6621074/public_html/m/write.php on line 76 Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpcmW3mo' to 'images/SmallSmileyFace.jpg' in /home/a6621074/public_html/m/write.php on line 76 This is the code: if (!empty($_FILES['fileImage']['name'])) { // check image type and size if ((($imagetype == 'image/gif') || ($imagetype == 'image/jpeg') || ($imagetype == 'image/pjpeg') || ($imagetype == 'image/png')) && ($imagesize > 0) && ($imagesize <= 32768)) { if ($_FILES['fileImage']['error'] == 0) { //move file $target = 'images/' . $image; if (move_uploaded_file($_FILES['fileImage']['tmp_name'], $target)) { $query = "INSERT INTO reviews (post_date, food_name, location, cafeteria, review, image, rating, user_id) VALUES (NOW(), '$foodname', '$location', '$cafeteria', '$review', '$image', $rate, $id)"; mysqli_query($dbc, $query); //confirm success echo '<p>Thank you for your submission!</p>'; } else { echo '<p class="errmsg">There was a problem uploading your image.</p>'; } } @unlink($_FILES['fileImage']['tmp_name']); } else { echo '<p class="errmsg">The screen shot must be a GIF, JPEG, or PNG image file no greater than 32KB in size.</p>'; } } Any ideas?

• Is there anything RAD comparible to VCL?

  - by mawg

  After years in embedded programmking, I have to develop a windows app. I dug out my old C++ builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP form Borland too. I realzie that MSVC, QT, NetBEans, etc are good enough IDEs for RAD, _BUT_ does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

• Click event keeps firing

  - by Ben Shelock

  I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

• Question about SQL Server HierarchyID depth-first performance

  - by AndalusianCat

  I am trying to implement hierarchyID in a table (dbo.[Message]) containing roughly 50,000 rows (will grow substantially in the future). However it takes 30-40 seconds to retrieve about 25 results. The root node is a filler in order to provide uniqueness, therefor every subsequent row is a child of that dummy row. I need to be able to traverse the table depth-first and have made the hierarchyID column (dbo.[Message].MessageID) the clustering primary key, have also added a computed smallint (dbo.[Message].Hierarchy) which stores the level of the node. Usage: A .Net application passes through a hierarchyID value into the database and I want to be able to retrieve all (if any) children AND parents of that node (besides the root, as it is filler). A simplified version of the query I am using: @MessageID hierarchyID /* passed in from application */ SELECT m.MessageID, m.MessageComment FROM dbo.[Message] as m WHERE m.Messageid.IsDescendantOf(@MessageID.GetAncestor((@MessageID.GetLevel()-1))) = 1 ORDER BY m.MessageID From what I understand, the index should be detected automatically without a hint. From searching forums I have seen people utilizing index hints, at least in the case of breadth-first indexes, as apparently CLR calls may be opaque to the query optimizer. I have spent the past few days trying to find a solution for this issue, but to no avail. I would greatly appreciate any assistance, and as this is my first post, I apologize in advance if this would be considered a 'noobish' question, I have read the MS documentation and searched countless forums, but have not came across a succinct description of the specific issue.

• how to make a explorer like logic in Obj C for iphone

  - by Ekra

  Hi friends, To make the query simple first we can take example:- If we open the explorer in our Windows desktop how it shows us the tree. As we keep on clicking the tree it get expanded and shows the file in it. The same way I want to show a explorer which gets expanded as the user clicks on it(I want to get the business logic the UI is simple). The information of the explorer i.e. which folder has what files come in a XML format to me. I have 2 options of getting the XML either I can get the whole XML at one query(but I guess this might slow the application if the XML is quite big). OR I can get the XML for every list like first only the root structure then if user clicks on any folder in root I can get the list(the files or folders inside that folder) of that particular folder. Now the question is What would be the approach to implement both the method and which would be the best. Should I need to create some dictionary to maintain the link of the files like which file is inside what. I am not able to get as how I would be able to link all the files. Any hint or direction would be highly appreciated. Thanks in advance

• Techniques for modeling a dynamic dataflow with Java concurrency API

  - by Maian

  Is there an elegant way to model a dynamic dataflow in Java? By dataflow, I mean there are various types of tasks, and these tasks can be "connected" arbitrarily, such that when a task finishes, successor tasks are executed in parallel using the finished tasks output as input, or when multiple tasks finish, their output is aggregated in a successor task (see flow-based programming). By dynamic, I mean that the type and number of successors tasks when a task finishes depends on the output of that finished task, so for example, task A may spawn task B if it has a certain output, but may spawn task C if has a different output. Another way of putting it is that each task (or set of tasks) is responsible for determining what the next tasks are. Sample dataflow for rendering a webpage: I have as task types: file downloader, HTML/CSS renderer, HTML parser/DOM builder, image renderer, JavaScript parser, JavaScript interpreter. File downloader task for HTML file HTML parser/DOM builder task File downloader task for each embedded file/link If image, image renderer If external JavaScript, JavaScript parser JavaScript interpreter Otherwise, just store in some var/field in HTML parser task JavaScript parser for each embedded script JavaScript interpreter Wait for above tasks to finish, then HTML/CSS renderer (obviously not optimal or perfectly correct, but this is simple) I'm not saying the solution needs to be some comprehensive framework (in fact, the closer to the JDK API, the better), and I absolutely don't want something as heavyweight is say Spring Web Flow or some declarative markup or other DSL. To be more specific, I'm trying to think of a good way to model this in Java with Callables, Executors, ExecutorCompletionServices, and perhaps various synchronizer classes (like Semaphore or CountDownLatch). There are a couple use cases and requirements: Don't make any assumptions on what executor(s) the tasks will run on. In fact, to simplify, just assume there's only one executor. It can be a fixed thread pool executor, so a naive implementation can result in deadlocks (e.g. imagine a task that submits another task and then blocks until that subtask is finished, and now imagine several of these tasks using up all the threads). To simplify, assume that the data is not streamed between tasks (task output-succeeding task input) - the finishing task and succeeding task won't exist together, so the input data to the succeeding task will not be changed by the preceeding task (since it's already done). There are only a couple operations that the dataflow "engine" should be able to handle: A mechanism where a task can queue more tasks A mechanism whereby a successor task is not queued until all the required input tasks are finished A mechanism whereby the main thread (or other threads not managed by the executor) blocks until the flow is finished A mechanism whereby the main thread (or other threads not managed by the executor) blocks until certain tasks have finished Since the dataflow is dynamic (depends on input/state of the task), the activation of these mechanisms should occur within the task code, e.g. the code in a Callable is itself responsible for queueing more Callables. The dataflow "internals" should not be exposed to the tasks (Callables) themselves - only the operations listed above should be available to the task. Note that the type of the data is not necessarily the same for all tasks, e.g. a file download task may accept a File as input but will output a String. If a task throws an uncaught exception (indicating some fatal error requiring all dataflow processing to stop), it must propagate up to the thread that initiated the dataflow as quickly as possible and cancel all tasks (or something fancier like a fatal error handler). Tasks should be launched as soon as possible. This along with the previous requirement should preclude simple Future polling + Thread.sleep(). As a bonus, I would like to dataflow engine itself to perform some action (like logging) every time task is finished or when no has finished in X time since last task has finished. Something like: ExecutorCompletionService<T> ecs; while (hasTasks()) { Future<T> future = ecs.poll(1 minute); some_action_like_logging(); if (future != null) { future.get() ... } ... } Are there straightforward ways to do all this with Java concurrency API? Or if it's going to complex no matter what with what's available in the JDK, is there a lightweight library that satisfies the requirements? I already have a partial solution that fits my particular use case (it cheats in a way, since I'm using two executors, and just so you know, it's not related at all to the web browser example I gave above), but I'd like to see a more general purpose and elegant solution.

• feedparser fails during script run, but can't reproduce in interactive python console

  - by Rhubarb

  It's failing with this when I run eclipse or when I run my script in iPython: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128) I don't know why, but when I simply execute the feedparse.parse(url) statement using the same url, there is no error thrown. This is stumping me big time. The code is as simple as: try: d = feedparser.parse(url) except Exception, e: logging.error('Error while retrieving feed.') logging.error(e) logging.error(formatExceptionInfo(None)) logging.error(formatExceptionInfo1()) Here is the stack trace: d = feedparser.parse(url) File "C:\Python26\lib\site-packages\feedparser.py", line 2623, in parse feedparser.feed(data) File "C:\Python26\lib\site-packages\feedparser.py", line 1441, in feed sgmllib.SGMLParser.feed(self, data) File "C:\Python26\lib\sgmllib.py", line 104, in feed self.goahead(0) File "C:\Python26\lib\sgmllib.py", line 143, in goahead k = self.parse_endtag(i) File "C:\Python26\lib\sgmllib.py", line 320, in parse_endtag self.finish_endtag(tag) File "C:\Python26\lib\sgmllib.py", line 360, in finish_endtag self.unknown_endtag(tag) File "C:\Python26\lib\site-packages\feedparser.py", line 476, in unknown_endtag method() File "C:\Python26\lib\site-packages\feedparser.py", line 1318, in _end_content value = self.popContent('content') File "C:\Python26\lib\site-packages\feedparser.py", line 700, in popContent value = self.pop(tag) File "C:\Python26\lib\site-packages\feedparser.py", line 641, in pop output = _resolveRelativeURIs(output, self.baseuri, self.encoding) File "C:\Python26\lib\site-packages\feedparser.py", line 1594, in _resolveRelativeURIs p.feed(htmlSource) File "C:\Python26\lib\site-packages\feedparser.py", line 1441, in feed sgmllib.SGMLParser.feed(self, data) File "C:\Python26\lib\sgmllib.py", line 104, in feed self.goahead(0) File "C:\Python26\lib\sgmllib.py", line 138, in goahead k = self.parse_starttag(i) File "C:\Python26\lib\sgmllib.py", line 296, in parse_starttag self.finish_starttag(tag, attrs) File "C:\Python26\lib\sgmllib.py", line 338, in finish_starttag self.unknown_starttag(tag, attrs) File "C:\Python26\lib\site-packages\feedparser.py", line 1588, in unknown_starttag attrs = [(key, ((tag, key) in self.relative_uris) and self.resolveURI(value) or value) for key, value in attrs] File "C:\Python26\lib\site-packages\feedparser.py", line 1584, in resolveURI return _urljoin(self.baseuri, uri) File "C:\Python26\lib\site-packages\feedparser.py", line 286, in _urljoin return urlparse.urljoin(base, uri) File "C:\Python26\lib\urlparse.py", line 215, in urljoin params, query, fragment)) File "C:\Python26\lib\urlparse.py", line 184, in urlunparse return urlunsplit((scheme, netloc, url, query, fragment)) File "C:\Python26\lib\urlparse.py", line 192, in urlunsplit url = scheme + ':' + url File "C:\Python26\lib\encodings\cp1252.py", line 15, in decode return codecs.charmap_decode(input,errors,decoding_table)

• In .net what are the difference between Eventlog and ManagementObject for retriving logs from remote

  - by Mitesh Patel

  I have found out following two ways for getting Application Event log entries from remote server. 1. Using EventLog object string logType = "Application"; EventLog ev = new EventLog(logType,"rspl200"); EventLogEntryCollection evColl = ev.Entries 2. Using ManagementObjectSearcher object ConnectionOptions co = new ConnectionOptions(); co.Username = "testA"; co.Password = "testA"; ManagementScope scope = new ManagementScope(@"\" + "machineName"+ @"\root\cimv2", co); scope.Connect(); SelectQuery query = new SelectQuery(@"select * from Win32_NtLogEvent"); EnumerationOptions opt = new EnumerationOptions(); opt.BlockSize = 1000; using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query,opt)) { foreach (ManagementObject mo in searcher.Get()) { // write down log entries Console.Writeline(mo["EventCode"]); } } I can easily get remote eventlog using method #1 (Using EventLog object) without any security access denied exception. But using method #2 (Using ManagementObjectSearcher object) i get access denied exception. Actually I want remote event log (only application and also latest log not all application logs) to be displayed in treeview like below - ServerName - Logs + Error + Information + Warning Can anybody help me in this to find out best way from this or any other? Also the main thing is that user who reads remote logs may be in different domain than server. Thanks Mitesh Patel

• Searching a list of tuples in python

  - by Niclas Nilsson

  I'm having a database (sqlite) of members of an organisation (less then 200 people). Now I'm trying to write an wx app that will search the database and return some contact information in a wx.grid. The app will have 2 TextCtrls, one for the first name and one for the last name. What I want to do here is make it possible to only write one or a few letters in the textctrls and that will start to return result. So, if I search "John Smith" I write "Jo" in the first TextCtrl and that will return every single John (or any one else having a name starting with those letters). It will not have an "search"-button, instead it will start searching whenever I press a key. One way to solve this would be to search the database with like " SELECT * FROM contactlistview WHERE forname LIKE 'Jo%' " But that seems like a bad idea (very database heavy to do that for every keystroke?). Instead i thought of use fetchall() on a query like this " SELECT * FROM contactlistview " and then, for every keystroke, search the list of tuples that the query have returned. And that is my problem: Searching a list is not that difficult but how can I search a list of tuples with wildcards?

• C# BackgroundWorker skips DoWork and goes straight to RunWorkerCompleted

  - by mr_man

  I'm new with C# so go easy on me! So far - I have a console app that listens for client connections and replies to the client accordingly. I also have a WPF form with a button and a text box. The button launches some code to connect to the server as a BackgroundWorker, which then waits for a response before appending it to the end of the text box. This works great, once. Sometimes twice. But then it kept crashing - turns out that the DoWork block wasn't being called at all and it was going straight to RunWorkerCompleted. Of course, the .result is blank so trying to convert it to a string fails. Is this a rookie mistake? I have tried searching the internet for various ways of saying the above but haven't come across anything useful... This is the code so far: http://pastebin.com/ZQvCFqxN - there are so many debug outputs from me trying to figure out exactly what went wrong. This is the result of the debug outputs: http://pastebin.com/V412mppX Any help much appreciated. Thanks! EDIT: The relevant code post-fix (thanks to Patrick Quirk below) is: public void dorequest(string query) { request = new BackgroundWorker(); request.WorkerSupportsCancellation = true; request.WorkerReportsProgress = true; request.ProgressChanged += request_ProgressChanged; request.DoWork += request_DoWork; request.RunWorkerCompleted += request_RunWorkerCompleted; request.RunWorkerAsync(query); }

• Designing a fluid Javascript interface to hide callback asynchrony

  - by Anurag

  How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

• rails search nested set (categories and sub categories)

  - by bob

  Hello, I am using the http://github.com/collectiveidea/awesome_nested_set awesome nested set plugin and currently, if I choose a sub category as my category_id for an item, I can not search by its parent. Category.parent Category.Child I choose Category.child as the category that my item is in. So now my item has category_id of 4 stored in it. If I go to a page in my rails application, lets say teh Category page and I am on the Category.parent's page, I want to show products that have category_id's of all the descendants as well. So ideally i want to have a find method that can take into account the descendants. You can get the descendants of a root by calling root.descendants (a built in plugin method). How would I go about making it so I can query a find that gets the descendants of a root instead of what its doing now which is binging up nothing unless the product had a specific category_id of the Category.parent. I hope I am being clear here. I either need to figure out a way to create a find method or named_scope that can query and return an array of objects that have id's corresponding tot he descendants of a root OR if I have any other options, what are they? I thought about creating a field in my products table like parent_id which can keep track of the parent so i can then create two named scopes one finding the parent stuff and one finding the child stuff and chaining them. I know I can create a named scope for each child and chain them together for multiple children but this seems a very tedious process and also, if you add more children, you would need to specify more named scopes.

• UCMA 3.0 How to build a list of recipients and then broadcast an IM call to those recipients

  - by ficuscr

  I am developing an application using UCMA 3.0 that will run as a service and send out periodic 'broadcasts' in the form of Instant Message calls. I have been using the book "Professional Unified Communications Development with Microsoft Lync Server 2010" and have everything provisioned fine and am able to establish an application endpoint. I am stuck on two aspects though. 1) How to get a list of all users of Lync? Everything the UCMA can do is centered on a single user. For example it allows me to retrieve all contacts/groups present on a given users 'contact list' but does not provide any means to query for a list of available contacts that could be added to one of those contact lists. On the MSDN forum I found this post which leads me to think my best bet is simply to query AD directly. 2) What is the best way to actually send a broadcast style IM? My working premise is to attempt something like what I've found in this code example (specifically the public void SendIM() method). So, get a list of recipients from AD, (looping on each on to check current presence?), and then use Automation to make the IM call for each recipient in the collection. Does that make sense? Do I need to check presence of the recipient or do I just optimistically make the IM calls irregardless of their current presence status? Can anyone point me to some working code demonstrating sending an IM broadcast? You would think this is probably one of the most common use cases however the SDK samples do not cover it. Thanks in advance.

• Numeric Order By In Transact SQL (Ordering As String Instead Of Int)

  - by Pyronaut

  I have an issue where I am trying to order a result set by what I believe to be a numberic column in my database. However when I get the result set, It has sorted the column as if it was a string (So alphabetically), instead of sorting it as an int. As an example. I have these numbers, 1 , 2, 3, 4, 5, 10, 11 When I order by in Transact SQL, I get back : 1, 10, 11, 2, 3, 4, 5 I had the same issue with Datagridview's a while back, And the issue was because of the sorting being done as if it was a string. I assume the same thing is happening here. My full SQL code is : SELECT TOP (12) DATEPART(YEAR, [OrderDate]) AS 'Year', DATEPART(MONTH, [OrderDate]) AS 'Month' , COUNT(OrderRef) AS 'OrderCount' FROM [Order] WHERE [Status] LIKE('PaymentReceived') OR [Status] LIKE ('Shipped') GROUP BY DATEPART(MONTH, [OrderDate]), DATEPART(YEAR, [OrderDate]) ORDER BY DATEPART(YEAR, OrderDate) DESC, DATEPART(MONTH, OrderDate) desc DO NOTE The wrong sorting only happens when I cam calling the function from Visual Studio. As in my code is : using (SqlConnection conn = GetConnection()) { string query = @"SELECT TOP (12) DATEPART(YEAR, [OrderDate]) AS 'Year', DATEPART(MONTH, [OrderDate]) AS 'Month' , COUNT(OrderRef) AS 'OrderCount' FROM [Order] WHERE [Status] LIKE('PaymentReceived') OR [Status] LIKE ('Shipped') GROUP BY DATEPART(MONTH, [OrderDate]), DATEPART(YEAR, [OrderDate]) ORDER BY DATEPART(YEAR, OrderDate) DESC, DATEPART(MONTH, OrderDate) desc"; SqlCommand command = new SqlCommand(query, conn); command.CommandType = CommandType.Text; using (SqlDataReader reader = command.ExecuteReader()) etc. When I run the statement in MSSQL server, there is no issues. I am currently using MSSQL 2005 express edition, And Visual Studio 2005. I have tried numerous things that are strewn across the web. Including using Convert() and ABS() to no avail. Any help would be much appreciated.

• How do I pass a callback function to sqlite3_exec on iOS 5.1?

  - by John Doh

  I am new to both xcode/iOS/Objective-C and sqlite. I am trying to teach myself the basics - and I would like to use the sqlite3 wrapper "sqlite3_exec" for a select query. For some reason, I can't find a simple example anywhere of someone doing this. Basically, the method has a parameter (the third one) for a callback function: int sqlite3_exec( sqlite3*, /* An open database */ const char *sql, /* SQL to be evaluated */ int (*callback)(void*,int,char**,char**), /* Callback function */ void *, /* 1st argument to callback */ char **errmsg /* Error msg written here */ ); That's fine. I'm no stranger to callbacks. However, I just can't seem to get the syntax down right. I took over one of the view controllers in my iPad (iOS 5.1) xcode (4.3) project, and made the changes shown below: #import "SecondViewController.h" #import "sqlite3.h" #import "AppState.h" @interface SecondViewController () @end @implementation SecondViewController - (int)myCallback:(void *)a_parm argc:(int)argc argv:(char **)argv column:(char **)column { return 0; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //grab questionnaire names char *sql = "select * from QST2Main order by [Name]"; char *err = nil; sqlite3 *db = [[AppState sharedManager] getgCn]; sqlite3_exec(db, sql, myCallback, nil, &err); } Essentially, I want to run a query when this view first loads, to store some data for later use. But, XCode doesn't like the "myCallback" usage at the bottom there. It says: Undeclared Use of Identifier 'myCallback.' That method is declared in the header file, and I've even tried making it static. Nothing seems to make this error go away. I know I must be doing something fundamentally wrong here, but for the life of me I can't figure out what - I can't even find other code samples in this area that could help me figure out what I'm missing. Many thanks!

• Using an NSButtonCell with template image in a NSTableView

  - by alloy

  In Interface Builder, I have set the dataCell of one of the columns of my NSTableView instance to be NSButtonCell. This works as expected, however, trying to use a ‘template’ image doesn't yield the expected visual result when clicking the button. How I configure the NSButtonCell: Image: NSRevealFreestandingTemplate Scaling: None Bezel: Bevel Type: Momentary Push In Bordered: false Expected result when clicking the button: Since the image is a ‘template’, the button should render its ‘on’ state. The background, ie the space surrounding the image, should not change. Actual result when clicking the button: No difference in the ‘state’ of the rendered image. The background color changes to white. Even-though I’ve tried my best to make the explanation of the problem as concise as possible, I’ve also made a simple screencast to visually illustrate the problem. And uploaded the demo app.

• Call dll - pcshll32.dll using delphi

  - by Davis

  Hi, I need to call hllapi function of pcshll32.dll using delphi. It's works with personal communications of ibm. How can i change the code bellow to delphi ? Thanks !!! The EHLLAPI entry point (hllapi) is always called with the following four parameters: EHLLAPI Function Number (input) Data Buffer (input/output) Buffer Length (input/output) Presentation Space Position (input); Return Code (output) The prototype for IBM Standard EHLLAPI is: [long hllapi (LPWORD, LPSTR, LPWORD, LPWORD); The prototype for IBM Enhanced EHLLAPI is: [long hllapi (LPINT, LPSTR, LPINT, LPINT); Each parameter is passed by reference not by value. Thus each parameter to the function call must be a pointer to the value, not the value itself. For example, the following is a correct example of calling the EHLLAPI Query Session Status function: #include "hapi_c.h" struct HLDQuerySessionStatus QueryData; int Func, Len, Rc; long Rc; memset(QueryData, 0, sizeof(QueryData)); // Init buffer QueryData.qsst_shortname = ©A©; // Session to query Func = HA_QUERY_SESSION_STATUS; // Function number Len = sizeof(QueryData); // Len of buffer Rc = 0; // Unused on input hllapi(&Func, (char *)&QueryData, &Len, &Rc); // Call EHLLAPI if (Rc != 0) { // Check return code // ...Error handling } All the parameters in the hllapi call are pointers and the return code of the EHLLAPI function is returned in the value of the 4th parameter, not as the value of the function.

• How do I Handle Ties When Ranking Results in MySQL?

  - by Laxmidi

  Hi, How does one handle ties when ranking results in a mysql query? I've simplified the table names and columns in this example, but it should illustrate my problem: SET @rank=0; SELECT student_names.students, @rank := @rank +1 AS rank, scores.grades FROM student_names LEFT JOIN scores ON student_names.students = scores.students ORDER BY scores.grades DESC So imagine the the above query produces: Students Rank Grades Al 1 90 Amy 2 90 George 3 78 Bob 4 73 Mary 5 NULL William 6 NULL Even though Al and Amy have the same grade, one is ranked higher than the other. Amy got ripped-off. How can I make it so that Amy and Al have the same ranking, so that they both have a rank of 1. Also, William and Mary didn't take the test. They bagged class and were smoking in the boy's room. They should be tied for last place. The correct ranking should be: Students Rank Grades Al 1 90 Amy 1 90 George 3 78 Bob 4 73 Mary 5 NULL William 5 NULL If anyone has any advice, please let me know. Thank you! -Laxmidi
