• fuzzy DISTINCT Values

  - by user982853

  I have a database of real estate listings and need to return a list of neighborhoods. Right now I am using mysql DISTINCT which returns all of the distinct values. My probelm is that there is a lot of neighborhoods that have similar names: example: Park View Sub 1 Park View Park View Sub 2 Park View Sub 3 Great Lake Sub 1 Great Lake Sub 2 Great Lake Great Lake Sub 3 I am looking for an easy php or mysql solution that would recognize that "Park View" and "Great Lake" already exists and ONLY return "Park View" and "Great Lake". My initial thought is to some how get the sort order by length so that the short values are at the top and then loop through using strstr. This sound like a large task I am wondering if there is a function either in mysql or php that would easily do this.

• Removing trailing newline character from fgets() input

  - by sfactor

  i am trying to get some data from the user and send it to another function in gcc. the code is something like this. printf("Enter your Name: "); if(!(fgets(Name, sizeof Name, stdin) != NULL)) { fprintf(stderr, "Error reading Name.\n"); exit(1); } However, i find that it has an \n character in the end. so if i enter John it ends up sending John\n. so how do i remove that \n and send a proper string.

• Making your class an event source in Java

  - by Crystal

  I'm making a custom button in Java that has two states, mousePressed, and mouseReleased. At the same time, if I wanted to reuse this button, so that other event listeners can register with it, are these the appropriate steps I should do: override addActionListener(ActionListener action) override removeActionListener(ActionListener action) have a private variable like List <ActionListener> list = new List <ActionListener>() to keep track of when events get added and some sort of function with for loop to run all the actions: public void runListeners() { for (ActionListener al : list) { al.actionPerfomed; } } I'm not really sure if this is the way you can do it or if there are other things I am missing. Like does my custom class have to be implements ActionListener? Thanks.

• maya "export all" window blocks my plugins script UI

  - by Hinchy

  I'm writing a custom File Translator for Maya which can export only (I have only declared the writer function). Currently having a problem with the MEL script which defines the plugin's options as a GUI. Currently I have a blank Maya scene, go to "file-export all". This creates the "File Export All" dialog, I then select my plugin exporter which runs my MEL script to create the bespoke options window. This new window is created behind the "File Export All" dialog and is not selectable! Do I have to place my export plugin specific options within the export all dialog rather than placing them in a separate window? Thanks for any links, tips or pointers you can provide.

• How to access fields in JSON object by index

  - by Stefan

  I know this isn't the best way to do it, but I have no other choice :( I have to access the items in JSONObject by their index. The standard way to access objects is to just wirte this[objectName] or this.objectName. I also found a method to get all the fields inside a json object: (for (var key in p) { if (p.hasOwnProperty(key)) { alert(key + " -> " + p[key]); } } (Soruce : Loop through Json object). However there is no way of accessing the JSONfields directly by a index. The only way I see right now, is to create an array, with the function above, get the fieldname by index and then get the value by fieldname. As far as I see it, the p (in our case the JSON file must be an iteratable array to, or else the foreach loop wouldn't work. How can I access this array directly? Or is it some kind of unsorted list? Regards, Stefan

• Removing a node from a linked list

  - by lost_with_coding

  I would like to create a delete_node function that deletes the node at the location in the list as a count from the first node. So far this is the code I have: class node: def __init__(self): self.data = None # contains the data self.next = None # contains the reference to the next node class linked_list: def __init__(self): self.cur_node = None def add_node(self, data): new_node = node() # create a new node new_node.data = data new_node.next = self.cur_node # link the new node to the 'previous' node. self.cur_node = new_node # set the current node to the new one. def list_print(self): node = ll.cur_node while node: print node.data node = node.next def delete_node(self,location): node = ll.cur_node count = 0 while count != location: node = node.next count+=1 delete node ll = linked_list() ll.add_node(1) ll.add_node(2) ll.add_node(3) ll.list_print()

• jQuery Sparklines: $.getJSON data can't be read

  - by Bob Jansen

  I'm trying to generate a pie graph with Sparklines but I'm running into some trouble. I can't seem to figure out what I'm doing wrong, but I feel it is a silly mistake. I'm using the following code to generate a sparkline chart in the div #traffic_bos_ss: //Display Visitor Screen Size Stats $.getJSON('models/ucp/traffic/traffic_display_bos.php', { type: 'ss', server: server, api: api, ip: ip, }, function(data) { var values = data.views; //alert(values); $('#traffic_bos_ss').sparkline(values, { type: "pie", height: "100%", tooltipFormat: 'data.screen - {{value}}', }); }); The JSON string fetched: {"screen":"1220x1080, 1620x1080, 1920x1080","views":"[2, 2, 61]"} For some reason Sparklines does not process the variable values. When I alert the variable it outputs "[2, 2, 61]". Now the jQuery code does work when I replace the snippet: var values = data.views; with var values = [2, 2, 61]; What am I doing wrong?

• Error with default argument in Source.getLines (Scala 2.8.0 RC1)

  - by Derek

  assuming I running Scala 2.8.0 RC1, the following scala code should print out the content of the file "c:/hello.txt" for ( line<-Source.fromPath( "c:/hello.txt" ).getLines ) println( line ) However, when I run it, I get the following error <console>:10: error: missing arguments for method getLines in class Source; follow this method with `_' if you want to treat it as a partially applied function Error occured in an application involving default arguments. val it = Source.fromPath("c:/hello.scala").getLines From what I understand, Scala should use the default argument "compat.Platform.EOL" for "getLines". I am wondering if I did wrong or is it a bug in scala 2.8 Thanks

• Trouble using SFML with GCC and OS X

  - by user1322654

  I've been trying to get SFML working for a while now and I've been trying to get it working using GCC. I'm on OS X by the way. I followed the standard Linux instructions and using the Linux 64-bit download however when it comes to compiling... g++ -o testing main.cpp -lsfml-system This happens: main.cpp: In function ‘int main()’: main.cpp:7: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:9: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:10: error: ‘Sleep’ is not a member of ‘sf’ So I thought it could be due to not using includes, so I changed my gcc compile command to: g++ -o testing main.cpp -I ~/SFML-1.6/include/ -lsfml-system and now I'm getting this error: ld: warning: ignoring file /usr/local/lib/libsfml-system.so, file was built for unsupported file format which is not the architecture being linked (x86_64) Undefined symbols for architecture x86_64: "sf::Clock::Clock()", referenced from: _main in ccZEiB7b.o "sf::Clock::GetElapsedTime() const", referenced from: _main in ccZEiB7b.o "sf::Sleep(float)", referenced from: _main in ccZEiB7b.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status** And I have no idea what to do to fix it.

• Typecast to a type from just the string representation of the type name

  - by Water Cooler v2

  sTypeName = ... //do some string stuff here to get the name of the type /* The Assembly.CreateInstance function returns a type of System.object. I want to type cast it to the type whose name is sTypeName. assembly.CreateInstance(sTypeName) So, in effect I want to do something like: */ assembly.CreateInstance(sTypeName) as Type.GetType(sTypeName); How do I do that? And, what do I take on the left side of the assignment expression, assuming this is C# 2.0. I don't have the var keyword.

• Prototype Ajax.Updater Response OK, but not showing up in FF. working in Safari!

  - by koko

  Hi, I've got a quite strange problem here. I'm calling some simple code via Ajax.Updater: new Ajax.Updater('load','http://myurl.com/demo.pl?key=demokey&param1=xyz&param2=abc',{ method:'get', onComplete:function(transport){ alert(transport.responseText) } }); which gets some code like this: <img id="2009_04_15_1239786246" src='../pv/100/2009_04_15_1239786246-01.jpg' border="1"> <img id="2009_04_15_1239786066" src='../pv/100/2009_04_15_1239786066-01.jpg' border="1"> ... and so on This code shows up in my firebug console as my server response, so everything should be fine. No errors here at all. Works fine in Safari. Firefox, according to Firebug, knows there is a response, but it won't show a thing in my div 'load' and the alert(transport.responseText) is also empty. I have no idea what could be the problem here.

• Why is this HTTP request continually looping?

  - by alex

  I'm probably overlooking something really obvious here. Comments are in to help explain any library specific code. public function areCookiesEnabled() { $random = 'cx67ds'; // set cookie cookie::set('test_cookie', $random); // try and get cookie, if not set to false $testCookie = cookie::get('test_cookie', false); $cookiesAppend = '?cookies=false'; // were we able to get the cookie equal ? $cookiesEnabled = ($testCookie === $random); // if $_GET['cookies'] === false , etc try and remove $_GET portion if ($this->input->get('cookies', false) === 'false' AND $cookiesEnabled) { url::redirect(str_replace($cookiesAppend, '', url::current())); // redirect return false; } // all else fails, add a $_GET[] if ( ! $cookiesEnabled) { url::redirect(url::current().$cookiesAppend); } return $cookiesEnabled; }

• Checking if a blob exists in Azure Storage

  - by John

  Hi, I've got a very simple question (I hope!) - I just want to find out if a blob (with a name I've defined) exists in a particular container. I'll be downloading it if it does exist, and if it doesn't then I'll do something else. I've done some searching on the intertubes and apparently there used to be a function called DoesExist or something similar... but as with so many of the Azure APIs, this no longer seems to be there (or if it is, has a very cleverly disguised name). Or maybe I'm missing something simple... :) John

• Groovy GDK equivalent of Apache Commons StringUtils.capitalize(str) or Perl's ucfirst(str)

  - by knorv

  Yes/no-question: Is there a Groovy GDK function to capitalize the first character of a string? I'm looking for a Groovy equivalent of Perl's ucfirst(..) or Apache Commons StringUtils.capitalize(str) (the latter capitalizes the first letter of all words in the input string). I'm currently coding this by hand using .. str = str[0].toUpperCase() + str[1 .. str.size() - 1] .. which works, but I assume there is a more Groovy way to do it. I'd imagine ucfirst(..) being a more common operation than say center(..) which is a standard method in the Groovy GDK (see http://groovy.codehaus.org/groovy-jdk/java/lang/String.html).

• ShellExecute not working from IDE but works otherwise.

  - by Altar

  I want to create and then open a txt file using the ShellExecute command. I have used this code for years with Delphi 7 and it worked: function Executa(CONST ExeName, Parameters: string): Boolean; begin if Parameters= '' then Result:= ShellExecute(0, 'open', PChar(ExeName), NIL , nil, SW_SHOWNORMAL)> 32 else Result:= ShellExecute(0, 'open', PChar(ExeName), PChar(Parameters), nil, SW_SHOWNORMAL)> 32; end; Now, I switch to Windows 7 (don't like it; they stuck it on my throat with my new laptop) 64 bit and the code is not working anymore when it runs from IDE. Delhi shows the CPU window with the caption "CPU-Process unknown (2352)". I close the CU windows and everything works fine until I close the application, when Delphi shows the CPU window one more time. If I run the app from outside IDE, it works fine. Looks like the debugger has something to say to me, but I don't know what.

• How to prevent Spell checking code in MS Office?

  - by Aaron

  We use MS Office. Outlook for emails, Word for some documentation and I use OneNote a lot for my own note taking. What bugs me is when I drop some code or use key words or even camel case into these apps the spell checking picks them up and I have red squiggles everywhere. Ignore is pretty much useless, so either I have to turn off Spell Check altogether start adding these to the custom dictionary. What would be good is if I can use the Set Language function to mark a whole block of text to just not be spell checked. Has anyone found a nice solution to this or do you know of a blank dictionary is best to use? I found using "Mohawk" kind of does that... might just use that for now. Maybe create a macro to switch between them.

• Using Javascript in Adobe Reader

  - by godleuf

  Hi, I am currently using the following script for a few documents: var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); How do I add another command, say document.close() so that it reads the print function and then follows the close document last? Do I simply add the close command right after the print command so it would read var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); document.close(); Thanks.

• Execute method with Action<T> argument using Reflection

  - by JGr

  How can i create a Action method to use as a argument to the following function? public void When(Action<T> action) { if (internalValue != null) action(internalValue); } I have the MethodInfo on the method, and the parameter type like so: var methods = value.GetType().GetMethods(); MethodInfo mInfo = methods.First(method => method.Name == "When"); Type parameterType = (mInfo.GetParameters()[0]).ParameterType; But after that i have no idea how to make the actual Action method to pass as argument, i also do not know how to define the Action method body.

• Bulkloading schema less entities on Google App Engine

  - by Rahul

  The new bulkloader added into SDK 1.3.4 works great for models that have a schema. For models inheriting db.Expando (or loosely defined schemas) i would like to understand what i would have to do to bulk upload them. I defined a custom connector, that implemented the ConnectorInterface and converted my data to the python dict required. How can i use this dict to define entities that get uploaded to the data store ? In the documentation there seems to be a post_import_function that can be used to return the entities that get uploaded. Is there an example on how this function is used ?

• get value of dynamiclly created radiobuttonlist

  - by Mark

  Hi All, I'm trying to get the value of a dynamically created radiobuttonlist via javascript to call a pagemethod. This is how I'm creating the rbl: rbl.Attributes["onclick"] = "javascript:preview('" + rbl.ID + "','" + rbl.ClientID + "');"; And this is the javascript: function preview(controlid, clientid) { var radio = document.getElementsByName(clientid); var answer = "k"; for (var ii = 0; ii < radio.length; ii++) { if (radio[ii].checked) answer = radio[ii].value; } PageMethods.SaveAnswer(controlid, answer); } The problem however is that I want to get the groupname of the radiobuttionlist so I can use getElementsByName, but i have no luck so far. Kind regards, Mark

• Is there a way to change the maximum width of a window without using the WM_GETMINMAXINFO message?

  - by David

  I want to change the imposed Windows maximum width that a window can be resized to, for an external application's window (not my C#/WinForms program's window). The documentation of GetSystemMetrics for SM_CXMAXTRACK says: "The default maximum width of a window that has a caption and sizing borders, in pixels. This metric refers to the entire desktop. The user cannot drag the window frame to a size larger than these dimensions. A window can override this value by processing the WM_GETMINMAXINFO message." Is there a way to modify this SM_CXMAXTRACK value (either system wide or for one particular window), without processing the WM_GETMINMAXINFO message? Maybe an undocumented function, a registry setting, etc.? (Or: The documentation for MINMAXINFO.ptMaxTrackSize says: "This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK." Maybe there is a way to change the size of the virtual screen?) Thank you

• Programatically Drop an External Div in JSTree

  - by Ted Mosbey

  I have a grid (slickgrid) which creates and destroys rows on the fly. I know jstree uses .jstree-draggable to find the external drag targets, but applying them to the grid rows doesn't work - such that I've thought of using the grid drag, and on finish of the grid drag I want to call the jstree "drag_finish": function (data) jQuery.jstree._reference($("#Tree")).dnd_finish(); The problem is that there is some null data. How would I Programatically Drop an External Div? How does jstree apply the .jstree-draggable targets? I could add the .jstree-draggable class to the grid drag helper, but it doesnt seem to fire when dropped on the tree although it clearly has the class. Any guidance would be greatly appreciated. Regards.

• Type patterns and generic classes in Haskell

  - by finnsson

  I'm trying to understand type patterns and generic classes in Haskell but can't seem to get it. Could someone explain it in laymen's terms? In [1] I've read that "To apply functions generically to all data types, we view data types in a uniform manner: except for basic predefined types such as Float, IO, and ?, every Haskell data type can be viewed as a labeled sum of possibly labeled products." and then Unit, :*: and :+: are mentioned. Are all data types in Haskell automatically versions of the above mentioned and if so how do I figure out how a specific data type is represented in terms of :*:, etc? The users guide for generic classes (ch. 7.16) at haskell.org doesn't mention the predefined types but shouldn't they be handled in every function if the type patterns should be exhaustive?
