• iterate through fb:random

  - by fusion

  does anyone know how i would fill data from mysql database in fb:random and iterate through it, to pick a random quote? fb:random $facebook->api_client->fbml_setRefHandle('quotes', '<fb:random> <fb:random-option>Quote 1</fb:random-option> <fb:random-option>Quote 2</fb:random-option> </fb:random>'); mysql data: $rowcount = mysql_result($result, 0, 0); $rand = rand(0,$rowcount-1); $result = mysql_query("SELECT cQuotes, vAuthor, cArabic, vReference FROM thquotes LIMIT $rand, 1", $conn) or die ('Error: '.mysql_error()); $row = mysql_fetch_array($result, MYSQL_ASSOC); if ( !$row ) { echo "Empty"; } else{ $fb_box = "<p>" . h($row['cArabic']) . "</p>"; $fb_box .= "<p>" . h($row['cQuotes']) . "</p>"; $fb_box .= "<p>" . h($row['vAuthor']) . "</p>"; $fb_box .= "<p>" . h($row['vReference']) . "</p>"; }

• Using Regex Replace when looking for un-escaped characters

  - by Daniel Hollinrake

  I've got a requirement that is basically this. If I have a string of text such as "There once was an 'ugly' duckling but it could never have been \'Scarlett\' Johansen" then I'd like to match the quotes that haven't already been escaped. These would be the ones around 'ugly' not the ones around 'Scarlett'. I've spent quite a while on this using a little C# console app to test things and have come up with the following solution. private static void RegexFunAndGames() { string result; string sampleText = @"Mr. Grant and Ms. Kelly starred in the film \'To Catch A Thief' but not in 'Stardust' because they'd stopped acting by then"; string rePattern = @"\\'"; string replaceWith = "'"; Console.WriteLine(sampleText); Regex regEx = new Regex(rePattern); result = regEx.Replace(sampleText, replaceWith); result = result.Replace("'", @"\'"); Console.WriteLine(result); } Basically what I've done is a two step process find those characters that have already been escaped, undo that then do everything again. It sounds a bit clumsy and I feel that there could be a better way.

• Range-based `for` statement definition redundancy

  - by GMan - Save the Unicorns

  Looking at n3092, in §6.5.4 we find the equivalency for a range-based for loop. It then goes on to say what __begin and __end are equal to. It differentiates between arrays and other types, and I find this redundant (aka, confusing). It says for arrays types that __begin and __end are what you expect: a pointer to the first and a pointer to one-past the end. Then for other types, __begin and __end are equal to begin(__range) and end(__range), with ADL. Namespace std is associated, in order to find the std::begin and std::end defined in <iterator>, §24.6.5. However, if we look at the definition of std::begin and std::end, they are both defined for arrays as well as container types. And the array versions do exactly the same as above: pointer to the first, pointer to one-past the end. Why is there a need to differentiate arrays from other types, when the definition given for other types would work just as well, finding std::begin and std::end? Some abridged quotes for convenience: §24.6.5 The range-based for statement — if _RangeT is an array type, begin-expr and end-expr are __range and __range + __bound, respectively, where __bound is the array bound. If _RangeT is an array of unknown size or an array of incomplete type, the program is ill-formed. — otherwise, begin-expr and end-expr are begin(_range) and end(_range), respectively, where begin and end are looked up with argument-dependent lookup (3.4.2). For the purposes of this name lookup, namespace std is an associated namespace. and §24.6.5 range access template T* begin(T (&array)[N]); Returns: array. template T* end(T (&array)[N]); Returns: array + N.

• Need some help/advice on WCF Per-Call Service and NServiceBus interop.

  - by Alexey

  I have WCF Per-Call service wich provides data for clients and at the same time is integrated with NServiceBus. All statefull objects are stored in UnityContainer wich is integrated into custom service host. NServiceBus is configured in service host and uses same container as service instances. Every client has its own instance context(described by Juval Lowy in his book in chapter about Durable Services). If i need to send request over bus I just use some kind of dispatcher and wait response using Thread.Sleep().Since services are per-call this is ok afaik. But I am confused a bit about messages from bus, that service must handle and provide them to clients. For some data like stock quotes I just update some kind of statefull object and and then, when clients invoke GetQuotesData() just provide data from this object. But there are numerous service messages like new quote added and etc. At this moment I have an idea to implement something like "Postman daemon" =)) and store this type of messages in instance context. Then client will invoke "GetMail()",recieve those messages and parse them. Problem is that NServiceBus messages are "Interface based" and I cant pass them over WCF, so I need to convert them to types derieved from some abstract class. Dunno what is best way to handle this situation. Will be very gratefull for any advice on this. Thanks in advance.

• Matching a Repeating Sub Series using a Regular Expression with PowerShell

  - by Hinch

  I have a text file that lists the names of a large number of Excel spreadsheets, and the names of the files that are linked to from the spreadsheets. In simplified form it looks like this: "Parent File1.xls" Link: ChildFileA.xls Link: ChildFileB.xls "ParentFile2.xls" "ParentFile3.xls" Blah Link: ChildFileC.xls Link: ChildFileD.xls More Junk Link: ChildFileE.xls "Parent File4.xls" Link: ChildFileF.xls In this example, ParentFile1.xls has embedded links to ChildFileA.xls and ChildFileB.xls, ParentFile2.xls has no embedded links, and ParentFile3.xls has 3 embedded links. I am trying to write a regular expression in PowerShell that will parse the text file producing output in the following form: ParentFile1.xls:ChildFileA.xls,ChildFileB.xls ParentFile3.xls:ChildFileC.xls,ChildFileD.xls,ChildFileE.xls etc The task is complicated by the fact that the text file contains a lot of junk between each of the lines, and a parent may not always have a child. Furthermore, a single file name may pass over multiple lines. However, it's not as bad as it sounds, as the parent and child file names are always clearly demarcated (the parent with quotes and the child with a prefix of Link: ). The PowerShell code I've been using is as follows: $content = [string]::Join([environment]::NewLine, (Get-Content C:\Temp\text.txt)) $regex = [regex]'(?im)\s*\"(.*)\r?\n?\s*(.*)\"[\s\S]*?Link: (.*)\r?\n?' $regex.Matches($content) | %{$_.Groups[1].Value + $_.Groups[2].Value + ":" + $_.Groups[3].Value} Using the example above, it outputs: ParentFile1.xls:ChildFileA.xls ParentFile2.xls""ParentFile3.xls:ChildFileC.xls ParentFile4.xls:ChildFileF.xls There are two issues. Firstly, the inclusion of the "" instead of a newline whenever a Parent without a Child is processed. And the second issue, which is the most important, is that only a single child is ever shown for each parent. I'm guessing I need to somehow recursively capture and display the multiple child links that exist for each parent, but I'm totally stumped as to how to do this with a regular expression. Amy help would be greatly appreciated. The file contains 100's of thousands of lines, and manual processing is not an option :)

• Overridden button control escaping content. How to stop it?

  - by RemotecUk

  Hi, I've got an ASP.Net button control that I have overridden to provide different functionality. the code looks as follows.. I'm overriding the Render method to surround the control with an <a>... /// <summary> /// Render Method /// </summary> /// <param name="writer"></param> protected override void Render(HtmlTextWriter writer) { base.CssClass = "euva-button-decorated"; writer.Write("<a class=\"euva-button\">"); base.Render(writer); writer.Write("</a>"); } When I check the generated source on the page, I find that where ASP.Net has injected its click handler it does the following... <a class="euva-button"><input type="submit" name="TestButton" value="Test Button" onclick="clickOnce(this);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;TestButton&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" id="TestButton" class="euva-button-decorated" /></a> ... it seems to be escaping the output for the double quotes which means that the browser cannot understand the javascript. How do I make the render method not escape the injected ASP.Net client click handler ?? Note I also have my own client click handler which is declared declaratively in the page mark-up.

• Best practices for Java logging from multiple threads?

  - by Jason S

  I want to have a diagnostic log that is produced by several tasks managing data. These tasks may be in multiple threads. Each task needs to write an element (possibly with subelements) to the log; get in and get out quickly. If this were a single-task situation I'd use XMLStreamWriter as it seems like the best match for simplicity/functionality without having to hold a ballooning XML document in memory. But it's not a single-task situation, and I'm not sure how to best make sure this is "threadsafe", where "threadsafe" in this application means that each log element should be written to the log correctly and serially (one after the other and not interleaved in any way). Any suggestions? I have a vague intuition that the way to go is to use a queue of log elements (with each one able to be produced quickly: my application is busy doing real work that's performance-sensitive), and have a separate thread which handles the log elements and sends them to a file so the logging doesn't interrupt the producers. The logging doesn't necessarily have to be XML, but I do want it to be structured and machine-readable. edit: I put "threadsafe" in quotes. Log4j seems to be the obvious choice (new to me but old to the community), why reinvent the wheel...

• ASP.NET MVC 2: How to write this Linq SQL as a Dynamic Query (using strings)?

  - by Dr. Zim

  Skip to the "specific question" as needed. Some background: The scenario: I have a set of products with a "drill down" filter (Query Object) populated with DDLs. Each progressive DDL selection will further limit the product list as well as what options are left for the DDLs. For example, selecting a hammer out of tools limits the Product Sizes to only show hammer sizes. Current setup: I created a query object, sent it to a repository, and fed each option to a SQL "table valued function" where null values represent "get all products". I consider this a good effort, but far from DDD acceptable. I want to avoid any "programming" in SQL, hopefully doing everything with a repository. Comments on this topic would be appreciated. Specific question: How would I rewrite this query as a Dynamic Query? A link to something like 101 Linq Examples would be fantastic, but with a Dynamic Query scope. I really want to pass to this method the field in quotes "" for which I want a list of options and how many products have that option. (from p in db.Products group p by p.ProductSize into g select new Category { PropertyType = g.Key, Count = g.Count() }).Distinct(); Each DDL option will have "The selection (21)" where the (21) is the quantity of products that have that attribute. Upon selecting an option, all other remaining DDLs will update with the remaining options and counts.

• How do I escape ampersands in batch files?

  - by Peter Mortensen

  How do I escape ampersands in a batch file (or from the Windows command line) in order to use the start command to open web pages with ampersands in the URL? Double quotes will not work with start; this starts a new command line window instead. Update 1: Wael Dalloul's solution works. In addition, if there are URL encoded characters (e.g. space is encoded as %20) in the URL and it is in a batch file then '%' must be encoded as '%%'. This is not the case in the example. Example, from the command line (CMD.EXE): start http://www.google.com/search?client=opera&rls=en&q=escape+ampersand&sourceid=opera&ie=utf-8&oe=utf-8 will result in http://www.google.com/search?client=opera being opened in the default browser and these errors in the command line window: 'rls' is not recognized as an internal or external command, operable program or batch file. 'q' is not recognized as an internal or external command, operable program or batch file. 'sourceid' is not recognized as an internal or external command, operable program or batch file. 'ie' is not recognized as an internal or external command, operable program or batch file. 'oe' is not recognized as an internal or external command, operable program or batch file. Platform: Windows XP 64 bit SP2.

• Why does output of fltk-config truncate arguments to gcc?

  - by James Morris

  I'm trying to build an application I've downloaded which uses the SCONS "make replacement" and the Fast Light Tool Kit Gui. The SConstruct code to detect the presence of fltk is: guienv = Environment(CPPFLAGS = '') guiconf = Configure(guienv) if not guiconf.CheckLibWithHeader('lo', 'lo/lo.h','c'): print 'Did not find liblo for OSC, exiting!' Exit(1) if not guiconf.CheckLibWithHeader('fltk', 'FL/Fl.H','c++'): print 'Did not find FLTK for the gui, exiting!' Exit(1) Unfortunately, on my (Gentoo Linux) system, and many others (Linux distributions) this can be quite troublesome if the package manager allows the simultaneous install of FLTK-1 and FLTK-2. I have attempted to modify the SConstruct file to use fltk-config --cflags and fltk-config --ldflags (or fltk-config --libs might be better than ldflags) by adding them like so: guienv.Append(CPPPATH = os.popen('fltk-config --cflags').read()) guienv.Append(LIBPATH = os.popen('fltk-config --ldflags').read()) But this causes the test for liblo to fail! Looking in config.log shows how it failed: scons: Configure: Checking for C library lo... gcc -o .sconf_temp/conftest_4.o -c "-I/usr/include/fltk-1.1 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT" gcc: no input files scons: Configure: no How should this really be done? And to complete my answer, how do I remove the quotes from the result of os.popen( 'command').read()? EDIT The real question here is why does appending the output of fltk-config cause gcc to not receive the filename argument it is supposed to compile?

• Convert array to CSV/TSV-formated string in Python.

  - by dreeves

  Python provides csv.DictWriter for outputting CSV to a file. What is the simplest way to output CSV to a string or to stdout? For example, given a 2D array like this: [["a b c", "1,2,3"], ["i \"comma-heart\" you", "i \",heart\" u, too"]] return the following string: "a b c, \"1, 2, 3\"\n\"i \"\"comma-heart\"\" you\", \"i \"\",heart\"\" u, too\"" which when printed would look like this: a b c, "1,2,3" "i ""heart"" you", "i "",heart"" u, too" (I'm taking csv.DictWriter's word for it that that is in fact the canonical way to output that array as CSV. Excel does parse it correctly that way, though Mathematica does not. From a quick look at the wikipedia page on CSV it seems Mathematica is wrong.) One way would be to write to a temp file with csv.DictWriter and read it back with csv.DictReader. What's a better way? TSV instead of CSV It also occurs to me that I'm not wedded to CSV. TSV would make a lot of the headaches with delimiters and quotes go away: just replace tabs with spaces in the entries of the 2D array and then just intersperse tabs and newlines and you're done. Let's include solutions for both TSV and CSV in the answers to make this as useful as possible for future searchers.

• learning to type - tips for programmers?

  - by OrbMan

  After hunting and pecking for about 35 years, I have decided to learn to type. I am learning QWERTY and have learned about 2/3 of the letters so far. While learning, I have noticed how asymmeterical the keyboard is, which really bothers me. (I will probably switch to a symmetrical keyboard eventually, but for now am trying to do everything as standard and "correct" as possible.) Although I am not there yet in my lessons, it seems that many of the keys I am going to use as a C# web developer are supposed to be typed by the pinky of my right hand. Are there any typing patterns you have developed that are more ergonomic (or faster) when typing large volumes of code rife with braces, colons, semi-colons and quotes? Or, should I just accept the fact that every other key is going to be hit with my right pinky? It is not that speed is such a huge concern, as much as that it seems so inefficient to rely on one finger so much... As an example, some of the conventions I use as a hunt and pecker, like typing open and close braces right away with my index and middle finger, and then hitting the left arrow key to fill in the inner content, don't seem to work as well with just a pinky. What are some typing patterns using a standard QWERTY keyboard that work really well for you as a programmer?

• Is Software Engineering Dead? [closed]

  - by nik

  Right from Jeff's blog: Software Engineering: Dead? I was utterly floored when I read this new IEEE article by Tom DeMarco (pdf). See if you can tell why. He quotes DeMarco, "I'm gradually coming to the conclusion that software engineering is an idea whose time has come and gone". Further, "What DeMarco seems to be saying -- and, at least, what I am definitely saying -- is that control is ultimately illusory on software development projects." I am writing these lines without context to invoke reading of the related subject. What are the views of the programming community here? I have started to realize that a community wiki is not getting the right amount of participation here. That is the reason I left this question out in the open, while still contemplating a change to CW. It was closed once, and I thought that was the end of it. But, now I see it was reopened and has more answers (all of which I have not yet read). However, I see a lot of CW requests and am forced to reconsider that. This is how I intend to make the CW decision here. There is a comment by Neil Butterworth requesting a CW at 12 upvotes -- "should be community wiki" There is a comment by Lance Roberts requesting no CW at 0 upvotes -- "+1 for not putting it in community wiki" The difference is 12 for a CW request at the moment If this difference becomes 5 more (that is 17), I'll move this question to CW, and it will not return back from there Of course, there is also a close vote at the moment; the question may be closed again.

• SubSonic 3.0 Simple Repository Adding a DateTime Property To An Object

  - by Blounty

  I am trying out SubSonic to see if it is viable to use on production projects. I seem to have stumbled upon an issue whith regards to updating the database with default values (String and DateTime) when a new column is created. If a new property of DateTime or String is added to an object. public class Bug { public int BugId { get; set; } public string Title { get; set; } public string Overview { get; set; } public DateTime TrackedDate { get; set; } public DateTime RemovedDate { get; set; } } When the code to add that type of object to the database is run var repository = new SimpleRepository(SimpleRepositoryOptions.RunMigrations); repository.Add(new Bug() { Title = "A Bug", Overview = "An Overview", TrackedDate = DateTime.Now }); it creates the following sql: UPDATE Bugs SET RemovedDate=''01/01/1900 00:00:00'' For some reason it is adding double 2 single quotes to each end of the string or DateTime. This is causing the following error: System.Data.SqlClient.SqlException - Incorrect syntax near '01' I am connecting to SQL Server 2005 Any help would be appreicated as apart from this issue i am finding SubSonic to be a great product. I have created a screen cast of my error here:

• Bash and regex problem : check for tokens entered into a Coke vending machine

  - by Michael Mao

  Hi all: Here is a "challenge question" I've got from Linux system programming lecture. Any of the following strings will give you a Coke if you kick: L = { aaaa, aab, aba, baa, bb, aaaa"a", aaaa"b", aab"a", … ab"b"a, ba"b"a, ab"bbbbbb"a, ... } The letters shown in wrapped double quotes indicate coins that would have fallen through (but those strings are still part of the language in this example). Exercise (a bit hard) show this is the language of a regular expression And this is what I've got so far : #!/usr/bin/bash echo "A bottle of Coke costs you 40 cents" echo -e "Please enter tokens (a = 10 cents, b = 20 cents) in a sequence like 'abba' :\c" read tokens #if [ $tokens = aaaa ]||[ $tokens = aab ]||[ $tokens = bb ] #then # echo "Good! now a coke is yours!" #else echo "Thanks for your money, byebye!" if [[ $token =~ 'aaaa|aab|bb' ]] then echo "Good! now a coke is yours!" else echo "Thanks for your money, byebye!" fi Sadly it doesn't work... always outputs "Thanks for your money, byebye!" I believe something is wrong with syntax... We didn't provided with any good reference book and the only instruction from the professor was to consult "anything you find useful online" and "research the problem yourself" :( I know how could I do it in any programming language such as Java, but get it done with bash script + regex seems not "a bit hard" but in fact "too hard" for anyone with little knowledge on something advanced as "lookahead"(is this the terminology ?) I don't know if there is a way to express the following concept in the language of regex: Valid entry would consist of exactly one of the three components : aaaa, aab and bb, regardless of order, followed by an arbitrary sequence of a or b's So this is what is should be like : (a{4}Ua{2}bUb{2})(aUb)* where the content in first braces is order irrelevant. Thanks a lot in advance for any hints and/or tips :)

• PHP Json Encoding w/ quote escaping in 5.2?

  - by NickAldwin

  I'm playing with the flickr api and php. I want to pass some information from PHP to Javascript through Ajax. I have the following code: json_encode($pics); which results in the following example JSON string: [{"id":"4363603591","title":"blue, white and red...another seattle view","date_faved":"1266379499"},{"id":"4004908219","title":"\u201cI just told you my dreams and you made me see that I could walk into the sun and I could still be me and now I can't deny nothing lasts forever.\u201d","date_faved":"1259987670"}] Javascript has problems with this, however, due to the unescaped single-quote in the second item ("can't deny"). I want to use the function json_encode with the options parameter to make it strip the quotes, but that's only available in PHP 5.3, and I'm running 5.2 (not my server). Is there a fast way to run through the entire array and escape everything before encoding it in Json? I looked for a way to do this, but it all seems to deal with encoding it as the data is generated, something I cannot do as I'm not the one generating the data. If it helps, I'm currently using the following javascript after the ajax request: var photos = eval('(' + resptxt + ')');

• How can I stop SQL Server Management Studio replacing 'SELECT *' with the column list ?

  - by Ben McIntyre

  SQL Server Mgmt Studio is driving me crazy. If I create a view and SELECT '*' from a table, it's all OK and I can save the view. Looking at the SQL for the view (eg.by scripting a CREATE) reveals that the 'SELECT *' really is saved to the view's SQL. But as soon as I reopen the view using the GUI (right click modify), SELECT * is replaced with a column list of all the columns in the table. How can I stop Management Studio from doing this ? I want my 'SELECT *' to remain just that. Perhaps it's just the difficulty of googling 'SELECT *' that prevented me from finding anything remotely relevant to this (i did put it in double quotes). Please, I am highly experienced in Transact-SQL, so please DON'T give me a lecture on why I shouldn't be using SELECT *. I know all the pros and cons and I do use it at times. It's a language feature, and like all language features can be used for good or evil (I emphatically do NOT agree that it is never appropriate to use it). Edit: I'm giving Marc the answer, since it seems it is not possible to turn this behaviour off. Problem is considered closed. I note that Enterprise Manager did no similar thing. The workaround is to either edit SQL as text, or go to a product other than Managment Studio. Or constantly edit out the column list and replace the * every time you edit a view. Sigh.

• Does posting data with a textarea automatically add slashes to (escape) the text?

  - by animuson

  Ok, so I'm having a problem with a simple textarea. I'm using a kind of hidden page to easily encode some data using JSON. However, all of my text input is automatically being escaped somewhere and I don't know where. All of my $_POST variables are automatically run through the htmlentities() function when the script starts up, as seen below: $ani->i->post = $this->clean($_POST, true); function clean($values, $unset = false) { if (is_array($values)) { foreach ($values as $key => $value) { $newkey = strtolower($key); $return[$newkey] = $this->clean($value); unset($values[$key]); } return $return; } return htmlentities($values); } I keep getting \' for all of my single quotes when I put the value back into the textarea. I can't find anywhere where it would be adding slashes and I don't remember it being a feature that they were automatically added when you submit from a textarea, and if that was so, why would they not be returning back to a single quote when put back into the textarea? Do I really need to run variables through stripslashes() to get them back to their original form? Edit: My 'test.php' file is as follows: <h1>To Be Encoded:</h1> <form action="/test" method="post"> <textarea name="encode" rows="20" cols="50"><?= html_entity_decode($ani->i->post['encode']) ?></textarea> <input type="submit" name="submit" value="Encode It!" /> </form> <h1>Encoded By JSON:</h1> <textarea name="encoded" rows="20" cols="50"><?= json_encode(html_entity_decode($ani->i->post['encode'])) ?></textarea> <?php die(); ?> P.S. The die() is just there for compatibility with my framework.

• 404 Not Found When Requesting URI With Encoded Patameters

  I am pretty sure this is some problem with the Apache configuration because it used to work on the previous hosting provider with the same PHP/MySQL configuration. In my application, users are able to delete photos by going to URIs like this: http://example.com/my-account/remove-media/id/9/ret/my-account%252Fedit-album%252Fid%252F1 The paramater id is an id of a photo to be removed, the parameter ret is a relative URL where user should be redirected after the removal of the photo but after clicking on a link like that I get 404 Not Found error with the text: Not Found The requested URL /public/my-account/remove-media/id/9/ret/my-account/edit-album/id/1 was not found on this server. Though it used to work on my previous hosting provider so I guess it is just some easy Apache configuration issue? One more thing, there is a htaccess file that changes the document root to /public: RewriteEngine On php_value upload_max_filesize 15M php_value post_max_size 15M php_value max_execution_time 200 php_value max_input_time 200 # Exclude some directories from URI rewriting #RewriteRule ^(dir1|dir2|dir3) - [L] RewriteRule ^\.htaccess$ - [F] RewriteCond %{REQUEST_URI} ="" RewriteRule ^.*$ /public/index.php [NC,L] RewriteCond %{REQUEST_URI} !^/public/.*$ RewriteRule ^(.*)$ /public/$1 RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^.*$ - [NC,L] RewriteRule ^public/.*$ /public/index.php [NC,L] In the public folder there is a second htaccess file for MVC: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ /index.php [NC,L] # Turn off magic quotes #php_flag magic_quotes_gpc off

• Binding a date string parameter in an MS Access PDO query

  - by harryg

  I've made a PDO database class which I use to run queries on an MS Access database. When querying using a date condition, as is common in SQL, dates are passed as a string. Access usually expects the date to be surrounded in hashes however. E.g. SELECT transactions.amount FROM transactions WHERE transactions.date = #2013-05-25#; If I where to run this query using PDO I might do the following. //instatiate pdo connection etc... resulting in a $db object $stmt = $db->prepare('SELECT transactions.amount FROM transactions WHERE transactions.date = #:mydate#;'); //prepare the query $stmt->bindValue('mydate', '2013-05-25', PDO::PARAM_STR); //bind the date as a string $stmt->execute(); //run it $result = $stmt->fetch(); //get the results As far as my understanding goes the statement that results from the above would look like this as binding a string results in it being surrounded by quotes: SELECT transactions.amount FROM transactions WHERE transactions.date = #'2013-05-25'#; This causes an error and prevents the statement from running. What's the best way to bind a date string in PDO without causing this error? I'm currently resorting to sprintf-ing the string which I'm sure is bad practise. Edit: if I pass the hash-surrounded date then I still get the error as below: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22018]: Invalid character value for cast specification: -3030 [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. (SQLExecute[-3030] at ext\pdo_odbc\odbc_stmt.c:254)' in C:\xampp\htdocs\ips\php\classes.php:49 Stack trace: #0 C:\xampp\htdocs\ips\php\classes.php(49): PDOStatement-execute() #1 C:\xampp\htdocs\ips\php\classes.php(52): database-execute() #2 C:\xampp\htdocs\ips\try2.php(12): database-resultset() #3 {main} thrown in C:\xampp\htdocs\ips\php\classes.php on line 49

• Setting Up OpenCV and .lib files

  - by jhaip

  I have been trying to set up OpenCV for the past few days with no results. I am using Windows 7 and VS C++ 2008 express edition. I have downloaded and installed OpenCV 2.1 and some of the examples work. I downloaded CMake and ran it to generate the VS project files and built all of them but there with several errors, and couldn't get any farther than that. When I ran CMake I configured it to use the VS 9 compiler, and then it brought up a list of items in red such as BUILD_EXAMPLES, BUILD_LATEX_DOCS, ect. All of them were unchecked except BUILD_NEW_PYTHON_SUPPORT, BUILD_TESTS, ENABLE_OPENMP, and OPENCV_BUILD_3RDPARTY_LIBS. I configured and generate without changing anything and then it generated the VS files such as ALL_BUILD.vcproj. I built the OpenCV VS solution in debug mode and it had 15 failures (maybe this is part of the problem or is it because I don't have python and stuff like that?) Now there was a lib folder created after building but inside there was just this VC++ Minimum Rebuild Dependency file and Program Debug Database file, both called cvhaartraining. I believe it should have created the .lib files I need instead of this. Also, the bin folder now has a folder called Debug with the same types of files with names like cv200d and cvaux200d. Believe I need those .lib files to move forward. I would also greatly appreciate if someone could direct me to a reliable tutorial to set up VS for OpenCV because I have been reading a lot of tutorials and they all say different things such as some say to configure Window's environment variables and other say files are located in folders such as OpenCV/cv which I don't have. I have gotten past the point of clear headed thinking so if anyone could offer some direction or a simple list of the files I need to link then I would be thankful. Also a side question: why when linking the OpenCV libs do you have to put them in quotes?

• How to access "Custom" or non-System TFS workitem fields using PowerShell?

  - by DaBozUK

  When using PowerShell to extract information from TFS, I find that I can get at the standard fields but not "Custom" fields. I'm not sure custom is the correct term, but for example if I look at the Process Editor in VS2008 and edit the Work Item type, there are fields such as listed below, with Name, Type and RefName: Title String System.Title State String System.State Rev Integer System.Rev Changed By String System.ChangedBy I can access these with Get-TfsItemHistory: Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table Title, State, Rev, ChangedBy -Auto So far so good. However, there are also some other fields in the WorkItem type, which I'm calling "Custom" or non-System fields, e.g.: Activated By String Microsoft.VSTS.Common.ActivatedBy Resolved By String Microsoft.VSTS.Common.ResolvedBy And the following command does not retrieve the data, just spaces. Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table ActivatedBy, ResolvedBy -Auto I've also tried the names in quotes, the fully qualified refname, but no luck. How do you access these "non-System" fields? Thanks Boz UPDATE: From Keith's answer I can get the fields I need: Get-TfsItemHistory "$/Hermes/Main" -Version "D01/12/10~" -Recurse ` | Select ChangeSetId, Comment -exp WorkItems ` | Select ChangeSetId, Comment, @{n='WI-Id'; e={$_.Id}}, Title -exp Fields ` | Where {$_.ReferenceName -eq 'Microsoft.VSTS.Common.ResolvedBy'} ` | Format-Table ChangesetId, Comment, WI-Id, Title, @{n='Resolved By'; e={$_.Value}} -Auto

• Conversion failed: SqlParameter and DateTime

  - by Tim

  I'm changing old,vulnerable sqlcommands with SqlParameters but get a SqlException: System.Data.SqlClient.SqlException {"Conversion failed when converting datetime from character string."} on sqlCommand.ExecuteScalar() Dim sqlString As String = _ "SELECT TOP 1 " & _ "fiSL " & _ "FROM " & _ "tabData AS D " & _ "WHERE " & _ "D.SSN_Number = '@SSN_Number' " & _ "AND D.fiProductType = 1 " & _ "AND D.Repair_Completion_Date > '@Repair_Completion_Date' " & _ "ORDER BY " & _ "D.Repair_Completion_Date ASC" Dim obj As Object Dim sqlCommand As SqlCommand Try sqlCommand = New SqlCommand(sqlString, Common.MyDB.SqlConn_RM2) sqlCommand.CommandTimeout = 120 sqlCommand.Parameters.AddWithValue("@SSN_Number", myClaim.SSNNumber) sqlCommand.Parameters.AddWithValue("@Repair_Completion_Date", myClaim.RepairCompletionDate) If Common.MyDB.SqlConn_RM2.State <> System.Data.ConnectionState.Open Then Common.MyDB.SqlConn_RM2.Open() obj = sqlCommand.ExecuteScalar() Catch ex As Exception Dim debug As String = ex.ToString Finally Common.MyDB.SqlConn_RM2.Close() End Try myClaim.RepairCompletionDate is a SQLDateTime. Do i have to remove the quotes in the sqlString to compare Date columns? But then i dont get a exception but incorrect results.
