• Javascript not showing up on Facebook Application's Profile Tab

  - by prateekdayal

  Hi, This may sound very noobish but I have tried to read the forum posts and docs on javascript behavior on Facebook's profile tabs. I understand that profile tabs don't support referencing external javascript but even my inline tags are not showing up on profile pages. In fact I am trying the fbjs-swf bridge and the code needed to instantiate the swf does not show up on the page <fb:fbjs_bridge/> <div id="swfContainer"></div> <script> var swf = document.createElement('fb:swf'); swf.setId('my_swf_id'); swf.setWidth('630'); swf.setHeight('520'); swf.setSWFSrc('http://www.muziboo.com/swf/player4-2.swf'); document.getElementById('swfContainer').appendChild(swf); document.getElementById('my_swf_id').callSWF('asMethod', 'one', 'two'); </script> I see a swf embedded (the one for the fbjs bridge) but I don't see any script tag containing the above javascript code. What am I missing? I can see the javascript code on canvas page though Thanks

• Algorithm to retrieve every possible combination of sublists of a two lists

  - by sgmoore

  Suppose I have two lists, how do I iterate through every possible combination of every sublist, such that each item appears once and only once. I guess an example could be if you have employees and jobs and you want split them into teams, where each employee can only be in one team and each job can only be in one team. Eg List<string> employees = new List<string>() { "Adam", "Bob"} ; List<string> jobs = new List<string>() { "1", "2", "3"}; I want Adam : 1 Bob : 2 , 3 Adam : 1 , 2 Bob : 3 Adam : 1 , 3 Bob : 2 Adam : 2 Bob : 1 , 3 Adam : 2 , 3 Bob : 1 Adam : 3 Bob : 1 , 2 Adam, Bob : 1, 2, 3 I tried using the answer to this stackoverflow question to generate a list of every possible combination of employees and every possible combination of jobs and then select one item from each from each list, but that's about as far as I got. I don't know the maximum size of the lists, but it would be certainly be less than 100 and there may be other limiting factors (such as each team can have no more than 5 employees) Update Not sure whether this can be tidied up more and/or simplified, but this is what I have ended up with so far. It uses the Group algorithm supplied by Yorye (see his answer below), but I removed the orderby which I don't need and caused problems if the keys are not comparable. var employees = new List<string>() { "Adam", "Bob" } ; var jobs = new List<string>() { "1", "2", "3" }; int c= 0; foreach (int noOfTeams in Enumerable.Range(1, employees.Count)) { var hs = new HashSet<string>(); foreach( var grouping in Group(Enumerable.Range(1, noOfTeams).ToList(), employees)) { // Generate a unique key for each group to detect duplicates. var key = string.Join(":" , grouping.Select(sub => string.Join(",", sub))); if (!hs.Add(key)) continue; List<List<string>> teams = (from r in grouping select r.ToList()).ToList(); foreach (var group in Group(teams, jobs)) { foreach (var sub in group) { Console.WriteLine(String.Join(", " , sub.Key ) + " : " + string.Join(", ", sub)); } Console.WriteLine(); c++; } } } Console.WriteLine(String.Format("{0:n0} combinations for {1} employees and {2} jobs" , c , employees.Count, jobs.Count)); Since I'm not worried about the order of the results, this seems to give me what I need.

• How to run unittest under pydev for Django?

  - by photon

  I configured properties for my django project under pydev. I can run the django app under pydev or under console window. I can also run unittest for app under console window. But I have problems to run unittest under pydev. I guess it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem?

• Can't access dojo object property using string variable

  - by Kareem

  I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

• Activator.CreateInstance fails in Windows Service

  - by kbe

  I have an issue with a Windows Service which throws a NullReference exception whenever I try to use var myType = Activator.CreateInstance(typeof(MyType)) There is no problem whenever I run the exact same code in a console window - and after debugging the obvious "which user is running this code" I doubt that it is a mere fact of changing the user running the service as I've tried to run the service using the computer's Administrator account as well as LocalSystem. I'm suspecting a Windows Update fiddling with default user rights but that's a bit of a desperate guess I feel. Remember: The type and assembly exist and works fine - otherwise I wouldn't be able to run the code in a console window. It is only when running in the context of a Windows Service I get an error. The question is: Can I in any way impersonate i.e. LocalSystem in a unittest by creating a GenericPrincipal (how would that GenericPrincipal look)?

• GEdit/Python execution plugin?

  - by Simon Woods

  Hi I'm just starting out learning python with GEdit plus various plugins as my IDE. Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console. Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome) ... or perhaps there is a better way to do code exploration? Many thx Simon

• Formatting Problem Date with DateTime

  - by Florian

  Hello, I want to display a date with this format : MM/dd/yyyy HH:mm:ss tt for example : 01/04/2011 03:34:03 PM but I have a problem with the following code class Program { static void Main(string[] args) { DateTime dt = new DateTime(DateTime.Today.Year, DateTime.Today.Month, DateTime.Today.Day, 0, 0, 0); string displayedDate = dt.ToString("MM/dd/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture); Console.WriteLine(displayedDate); Console.Read(); } } displays : 01/04/2011 12:00:00 AM instead of 01/04/2011 00:00:00 AM Anyone knows why ? Thank you !

• How to write a custom solution using a python package, modules etc

  - by morpheous

  I am writing a packacge foobar which consists of the modules alice, bob, charles and david. From my understanding of Python packages and modules, this means I will create a folder foobar, with the following subdirectories and files (please correct if I am wrong) foobar/ __init__.py alice/alice.py bob/bob.py charles/charles.py david/david.py The package should be executable, so that in addition to making the modules alice, bob etc available as 'libraries', I should also be able to use foobar in a script like this: python foobar --args=someargs Question1: Can a package be made executable and used in a script like I described above? Question 2 The various modules will use code that I want to refactor into a common library. Does that mean creating a new sub directory 'foobar/common' and placing common.py in that folder? Question 3 How will the modules foo import the common module ? Is it 'from foobar import common' or can I not use this since these modules are part of the package? Question 4 I want to add logic for when the foobar package is being used in a script (assuming this can be done - I have only seen it done for modules) The code used is something like: if __name__ == "__main__": dosomething() where (in which file) would I put this logic ?

• Javascript "this" variable confusion

  - by Assaf M

  Hi I am currently reading the book "Javascript: The Good Parts" and was playing with Functions. I produced a test script to test some properties and I am somewhat confused by the results. Here is the code: <h3>Object</h3> <div style="padding-left: 10px;"> <script type="text/javascript"> function outterF() { document.writeln("outterF.this = " + this + "<br>"); function innerF() { document.writeln("innerF.this = " + this + "<br>"); return this; }; var inner = innerF(); return this; } document.writeln("<b>From Inside:</b><br>"); var outF = outterF(); var inF = outF.inner; document.writeln("<br>"); document.writeln("<b>From Outside:</b><br>"); document.writeln("outterF.this = " + outF + "<br>"); document.writeln("innerF.this = " + inF + "<br>"); </script> </div> Result is: Object From Inside: outterF.this = [object Window] innerF.this = [object Window] From Outside: outterF.this = [object Window] innerF.this = undefined Notice that outF.inner returns "undefined", is that some kind of a language bug? Obviously, outF.inner points to Window object that has nothing to do with my object but shouldn't it be at least pointing to a Function object instead? Thanks -Assaf

• Facebook og:url ignored in favour of a Facebook hosted page about the og entity

  - by Dan

  I am trying to implement the Like button on my pages. Those pages represent the review page for a product. When a user Likes the page, it shows up in Facebook (not as a link, but as liking an entity), however when you click on the entity in Facebook it links through to a facebook.com hosted page representing the page. I want the user to be redirected to the og:url page? This happens for example when you Like an artist page on Grroveshar: http://grooveshark.com/#!/artist/Elbow/4795 I am clearly "doing it wrong". I am using the following markup to include the SDK. MYAPPID is included by the code generator Facebook provides so I assume it is required. <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=MYAPPID"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> Then my code to render the Like button. <div class="fb-like" data-send="false" data-width="450" data-show-faces="true"></div> And finally my og tags: <meta property="og:title" content="My product" /> <meta property="og:type" content="product" /> <meta property="og:url" content="http://site.com/product_1/" /> <meta property="og:image" content="http://site.com/image1.jpg" /> <meta property="og:site_name" content="My-Site-Name.com" /> <meta property="fb:admins" content="MYFACEBOOKID" /> <meta property="fb:app_id" content="MYAPPID" /> Thanks!

• How can I download all files of a specific type from a website using PHP?

  - by CheeseConQueso

  I want to get all midi (*.mid) files from a site that's set up pretty simple in terms of directory tree structure. I wish we had wget installed here, but that's another party.... The site is VGMusic.com and the path containing all of the midi files is: http://www.vgmusic.com/music/console/nintendo/nes/ I tried glob'ing it out, but I suppose that glob only works locally? Here is what I wrote to try to make it happen (doesn't work.. obviously..): <?php echo 'not a blizzard<br>'; foreach(glob('http://www.vgmusic.com/music/console/nintendo/nes/*.mid') as $filename) { echo $filename.'<br>'; //$newfile = 'http://www.mydomain.com/nes/'.$filename; //copy($filename, $newfile) } ?> I tried it also without the http:// in there with no luck.

• How do I process the configure file when cross-compiling with mingw?

  - by vy32

  I have a small open source program that builds with an autoconf configure script. I ran configure I tried to compile with: make CC="/opt/local/bin/i386-mingw32-g++" That didn't work because the configure script found include files that were not available to the mingw system. So then I tried: ./configure CC="/opt/local/bin/i386-mingw32-g++" But that didn't work; the configure script gives me this error: ./configure: line 5209: syntax error near unexpected token `newline' ./configure: line 5209: ` *_cv_*' Because of this code: # The following way of writing the cache mishandles newlines in values, # but we know of no workaround that is simple, portable, and efficient. # So, we kill variables containing newlines. # Ultrix sh set writes to stderr and can't be redirected directly, # and sets the high bit in the cache file unless we assign to the vars. ( for ac_var in `(set) 2>&1 | sed -n 's/^\(a-zA-Z_a-zA-Z0-9_*\)=.*/\1/p'`; do eval ac_val=\$$ac_var case $ac_val in #( *${as_nl}*) case $ac_var in #( *_cv_* fi Which is generated then the AC_OUTPUT is called. Any thoughts? Is there a correct way to do this?

• Is it possible to unstick a remote IIS ASP server after an exception hangs the session?

  - by user89691

  I have been coding an app in classic ASP that accesses 2 Access databases. I had a page I was working on throw an exception, which is normal during development and causes no lasting problems. This time however, after the exception any attempt to open either of the databases would freeze the session with an infinite script timeout. If I delete the session cookie I an able to access ASP pages again until I try to open the database again. The database that was open when the exception was thrown is left open. There is a LDB lock file and I can't rename or delete either the LDB or MDB file, though I can download the MDB file with FTP. The 2nd access database is not open but any attempt to read this also hangs the session. Accessing HTML pages is fine. The site is hosted with Hostway and they are not interested ("Coding problem = Your problem" even though it leaves my site dead in the water, I suspect until the next reboot, whenever that might be). Here is the dump from the relevant ASP page that threw the exception: Active Server Pages error 'ASP 0115' Unexpected error /translatestats.asp A trappable error (C0000005) occurred in an external object. The script cannot continue running. Active Server Pages error 'ASP 0240' Script Engine Exception /translatestats.asp A ScriptEngine threw exception 'C0000005' in 'IActiveScript::Close()' from 'CActiveScriptEngine::FinalRelease()'. Is there any way I can unstick the site / force close the database remotely ?

• State machines in C#

  - by Sir Psycho

  Hi, I'm trying to work out what's going on with this code. I have two threads iterating over the range and I'm trying to understand what is happening when the second thread calls GetEnumerator(). This line in particular (T current = start;), seems to spawn a new 'instance' in this method by the second thread. Seeing that there is only one instance of the DateRange class, I'm trying to understand why this works. Thanks in advance. class Program { static void Main(string[] args) { var daterange = new DateRange(DateTime.Now, DateTime.Now.AddDays(10), new TimeSpan(24, 0, 0)); var ts1 = new ThreadStart(delegate { foreach (var date in daterange) { Console.WriteLine("Thread " + Thread.CurrentThread.ManagedThreadId + " " + date); } }); var ts2 = new ThreadStart(delegate { foreach (var date in daterange) { Console.WriteLine("Thread " + Thread.CurrentThread.ManagedThreadId + " " + date); } }); Thread t1 = new Thread(ts1); Thread t2 = new Thread(ts2); t1.Start(); Thread.Sleep(4000); t2.Start(); Console.Read(); } } public class DateRange : Range<DateTime> { public DateTime Start { get; private set; } public DateTime End { get; private set; } public TimeSpan SkipValue { get; private set; } public DateRange(DateTime start, DateTime end, TimeSpan skip) : base(start, end) { SkipValue = skip; } public override DateTime GetNextElement(DateTime current) { return current.Add(SkipValue); } } public abstract class Range<T> : IEnumerable<T> where T : IComparable<T> { readonly T start; readonly T end; public Range(T start, T end) { if (start.CompareTo(end) > 0) throw new ArgumentException("Start value greater than end value"); this.start = start; this.end = end; } public abstract T GetNextElement(T currentElement); public IEnumerator<T> GetEnumerator() { T current = start; do { Thread.Sleep(1000); yield return current; current = GetNextElement(current); } while (current.CompareTo(end) < 1); } System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() { return GetEnumerator(); } }

• How to set the Cell height as dynamically in iPhone?

  - by Pugal Devan

  Hi Friends, In my apps, i have created table view and displayed the images and the labels in the table view. I have downloaded the image and set the image height into the another class, so i have set the image height as delegate value. In my problem is, heightForRowAtIndexPath method is call very earlier and it never calls again. So how i set the cell height depends on the image height? - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { In Console: the height of the image is --------------------------0.000000 the height of the image is --------------------------0.000000 the height of the image is --------------------------0.000000 } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { In Console: the height of the image is --------------------------98.567039 the height of the image is --------------------------300.000000 the height of the image is --------------------------232.288406 } Is any possible to call the heightforRowAtIndexPath method inside the cellForRowAt method. Because i have set the cell frame size and height depends on the image height. So how can i set the cell height depends on the image height?, please guide me. Thanks!

• response.Text is undefined when returning variable

  - by George

  Not sure if the problem is related to Ajax or something silly about JavaScript that I'm overlooking in general, but I have the following script where fox.html is just plain text that reads, "The quick brown fox jumped over the lazy dog." : function loadXMLDoc() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","fox.html",true); xmlhttp.send(); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { fox = xmlhttp.responseText; alert(fox); } } } onload = loadXMLDoc; The above script alerts the contents of fox.html onload just fine. However if I change the script so that: { fox = xmlhttp.responseText; alert(fox); } becomes: { fox = xmlhttp.responseText; return fox; } and alert(loadXMLDoc()); onload I get 'undefined'. I'm wondering why this is so.

• How to disable WinMain entry point for a MFC application?

  - by Sorin Sbarnea

  I understand that is not possible to have applications with multiple entry points under Windows. I have a MFC application and I added code for making it running as a service (main() entry point and other required stuff) but it looks that Windows will always run the WinMain() from MFC instead of my main. The question is how can I disable the WinMain() from MFC in order to be able to run my own main(). Probably the same problem would apply if you want to run the same application as a console application. What do I have to change in project properties in order to build it as a console application (main instead of WinMain)? Is commenting my CWinApp the only solution?

• Moving a large number of files in one directory to multiple directories

  - by Axsuul

  I am looking to create a Windows batch script to move about 2,000 files and splitting them up so that there are 10 files per folder. I have attempted creating a batch script but the syntax really boggles my mind. Here is what I have so far @echo off :: Config parameters set /a groupsize = 10 :: initial counter, everytime counter is 1, we create new folder set /a n = 1 :: folder counter set /a nf = 1 for %%f in (*.txt) do ( :: if counter is 1, create new folder if %n% == 1 ( md folder%nf% set /a n += 1 ) :: move file into folder mv -Y %%f folder%nf%\%%f :: reset counter if larger than group size if %n% == %groupsize% ( set /a n = 1 ) else ( set /a n += 1 ) ) pause Basically what this script does is loop through each .txt file in the directory. It creates a new directory in the beginning and moves 10 files into that directory, then creates a new folder again and moves another 10 files into that directory, and so on. However, I'm having problems where the n variable is not being incremented in the loop? I'm sure there's other errors too since the CMD window closes on me even with pause. Any help or guidance is appreciated, thanks for your time!

• Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

  - by BeachRunnerJoe

  I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

• Cannot upload media via Wordpress uploader

  - by Justin Johnson

  This has to do with media uploading in Wordpress. Every time WP creates a folder for new uploads (it organizes uploads by year and month: yyyy/mm), it creates it with the "apache:apache' user and group, with full access to all (777 or drwxrwxrwx). However, after that, WP cannot create a folder within that folder (e.g.: mkdir 2011 succeeds, but mkdir 2011/01 fails). Also, uploads cannot be moved into these newly created folders even though the permissions are 777 (rwxrwxrwx). Once a month, I have to chown the newly created folders to be the same as user:group as the rest of the files. Once I do that, uploading works fine (which doesn't make sense to me The really frustrating part is that this problem doesn't exist in other WP installs on other domains on the same server. * I wasn't sure if this should be here or on serverfault. Edit: The containing directory /.../httpdocs/blog/wp-content/uploads has the correct ownership drwxrwxrwx 5 myuser psaserv 4096 Jun 3 18:38 uploads This is a Plesk/CentOS environment hosted by Media Temple (dv). I've written the following test script to simulate the problem <pre><?php $d = "d" . mt_rand(100, 500); var_dump( get_current_user(), $d, mkdir($d), chmod($d, 0777), mkdir("$d/$d"), chmod("$d/$d", 0777), fileowner($d), getmyuid() ); The script always creates the first directory mkdir($d) successfully. On domain A, where the WP problem is, it cannot create the nested directory mkdir("$d/$d"). However, on domain B, both directories are successfully created. I am running each script at /var/www/vhosts/domainA/httpdocs/tmp/t.php and /var/www/vhosts/domainB/httpdocs/tmp/t.php respectively I checked the permissions on tmp, httpdocs, and domain[AB] and they are the same for each path. The only thing that differs is the user.

• Why is the event object different coming from jquery bind vs. addEventListener

  - by yodaisgreen

  Why is it when I use the jQuery bind the event object I get back is different from the event object I get back using addEventListener? The event object resulting from this jQuery bind does not have the targetTouches array (among other things) but the event from the addEventListener does. Is it me or is something not right here? $(document).ready (function () { $("#test").bind("touchmove", function (event) { console.log(event.targetTouches[0].pageX); // targetTouches is undefined }); }); vs. $(document).ready (function () { var foo = document.querySelectorAll('#test') foo[0].addEventListener('touchmove', function (event) { console.log(event.targetTouches[0].pageX); // returns the correct values }, false); });

• VBScript: Disable caching of response from server to HTTP GET URL request

  - by Rob

  I want to turn off the cache used when a URL call to a server is made from VBScript running within an application on a Windows machine. What function/method/object do I use to do this? When the call is made for the first time, my Linux based Apache server returns a response back from the CGI Perl script that it is running. However, subsequent runs of the script seem to be using the same response as for the first time, so the data is being cached somewhere. My server logs confirm that the server is not being called in those subsequent times, only in the first time. This is what I am doing. I am using the following code from within a commercial application (don't wish to mention this application, probably not relevant to my problem): With CreateObject("MSXML2.XMLHTTP") .open "GET", "http://myserver/cgi-bin/nsr/nsr.cgi?aparam=1", False .send nsrresponse =.responseText End With Is there a function/method on the above object to turn off caching, or should I be calling a method/function to turn off the caching on a response object before making the URL? I looked here for a solution: http://msdn.microsoft.com/en-us/library/ms535874(VS.85).aspx - not quite helpful enough. And here: http://www.w3.org/TR/XMLHttpRequest/ - very unfriendly and hard to read. I am also trying to force not using the cache using http header settings and html document header meta data: Snippet of server-side Perl CGI script that returns the response back to the calling client, set expiry to 0. print $httpGetCGIRequest-header( -type = 'text/html', -expires = '+0s', ); Http header settings in response sent back to client: <html><head><meta http-equiv="CACHE-CONTROL" content="NO-CACHE"></head> <body> response message generated from server </body> </html> The above http header and html document head settings haven't worked, hence my question.

• Generating MySQL UPDATE statements containing BLOB image data

  - by Bob

  I'm trying to write an SQL statement that will generate an SQL script that will update a BLOB field with an IMAGE being selected from the database. This is what I have: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = ', QUOTE( THUMBNAIL ), ' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; In the above, THUMBNAIL is a BLOB field containing raw image data. When I run the resulting script I get the following error: ERROR at line 2: Unknown command '\\'. I first tried this without the QUOTE() function, like so: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = \'', THUMBNAIL, '\' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; Running the resulting script produces this error: ERROR at line 2: Unknown command '\0'. What is the proper function to apply to this BLOB field in the select, so the UPDATE statements will work? If context is required, I'm looking to migrate thumbnails generated on one server to another server for certain image IDs only. I would use mysqldump, but I don't want to clobber the entire table. Any help is greatly appreciated!
