• facebook graph api does not return all feed items on facebook page

  - by Nick Franceschina

  at the time of this question, if you go here: http://www.facebook.com/realplayer you'll see six posts down, I have posted a photo with a message of "#highfive Cincinnati, OH" but if you to either of these: http://graph.facebook.com/realplayer/feed http://graph.facebook.com/realplayer/tagged the JSON that is returned seemingly includes everything on the wall, except for MY post. there is another photo post from someone else down below mine, and it is showing up (and both my photo and his photo are in the "Fan photos" section) obviously, since I can see everything with these links already, it appears that access_token is not a part of the equation... BUT, some more info: if I use an access_token from a session that isn't me, I can't see the post in the JSON if I use an access_token from MY logged in session, then I DO see the post in the JSON so I'm very confused. if everyone in the world can see those posts on the wall without even authenticating, then I expect all of them to come back in the graph api as well. anyone have thoughts on this? I am aware of the "manage_page" permission... which I can use to get a list of accounts and special offline access tokens for those pages... and that's something I can explore... but it seems like alot of work when my post seemingly SHOULD be there in the graph

• Assigning a value to a variable gets stored in the wrong spot?

  - by scribbloid

  Hello, I'm relatively new to C, and this is baffling me right now. It's part of a much larger program, but I've written this little program to depict the problem I'm having. #include <stdio.h> int main() { signed int tcodes[3][1]; tcodes[0][0] = 0; tcodes[0][1] = 1000; tcodes[1][0] = 1000; tcodes[1][1] = 0; tcodes[2][0] = 0; tcodes[2][1] = 1000; tcodes[3][0] = 1000; tcodes[3][1] = 0; int x, y, c; for(c = 0; c <= 3; c++) { printf("%d %d %d\r\n", c, tcodes[c][0], tcodes[c][1]); x = 20; y = 30; } } I'd expect this program to output: 0 0 1000 1 1000 0 2 0 1000 3 1000 0 But instead, I get: 0 0 1000 1 1000 0 2 0 20 3 20 30 It does this for any number assigned to x and y. For some reason x and y are overriding parts of the array in memory. Can someone explain what's going on? Thanks!

• Spring Data Neo4J @Indexed(unique = true) not working

  - by Markus Lamm

  I'm new to Neo4J and I have, probably an easy question. There're NodeEntitys in my application, a property (name) is annotated with @Indexed(unique = true) to achieve the uniqueness like I do in JPA with @Column(unique = true). My problem is, that when I persist an entity with a name that already exists in my graph, it works fine anyway. But I expected some kind of exception here...?! Here' s an overview over basic my code: @NodeEntity public abstract class BaseEntity implements Identifiable { @GraphId private Long entityId; ... } public class Role extends BaseEntity { @Indexed(unique = true) private String name; ... } public interface RoleRepository extends GraphRepository<Role> { Role findByName(String name); } @Service public class RoleServiceImpl extends BaseEntityServiceImpl<Role> implements { private RoleRepository repository; @Override @Transactional public T save(final T entity) { return getRepository().save(entity); } } And this is my test: @Test public void testNameUniqueIndex() { final List<Role> roles = Lists.newLinkedList(service.findAll()); final String existingName = roles.get(0).getName(); Role newRole = new Role.Builder(existingName).build(); newRole = service.save(newRole); } That's the point where I expect something to go wrong! How can I ensure the uniqueness of a property, without checking it for myself?? THANKS IN ADVANCE FOR ANY IDEAS!! P.S.: I'm using neo4j 1.8.M07, spring-data-neo4j 2.1.0.BUILD-SNAPSHOT and Spring 3.1.2.RELEASE.

• Setting up a web development/build environment

  - by Eric

  Hello all, My current project has a development web server and live web server. Developers make changes to files on the dev server and test them (by going to the dev address) and make changes as necessary. When the file or files are ready to go, they are copied to the live server. There is no version control. As you might expect, there are some problems with this model: It's hard to keep track of what other programmers have done. It's hard to keep track of what files should be copied to the live server. There is no version control. I'm in a position to make nearly any change I like, but I want it to be the right one! I have been turning this over in my head for quite a while, and I have a solution that might be okay. But I want SO's opinion. Certainly version control needs to be added. But how should it work with the existing codebase and where should the developers be testing? How can anyone know what needs to be moved to the live server? What other details need to be addressed? How would you attack this problem? Supplementary information: The website is vital, but not mission critical. A small amount of downtime is acceptable. There are very few developers. (Right now, only 4.) History: Before I started, the project used Visual Source Safe. This was a sufficiently bad experience that they quit using it and abandoned version control. The project is an ASP.NET (C#) website. This seems like a question that may have a complicated answer. Thanks for thinking about it!

• Haskell Cons Operator (:)

  - by Carson Myers

  I am really new to Haskell (Actually I saw "Real World Haskell" from O'Reilly and thought "hmm, I think I'll learn functional programming" yesterday) and I am wondering: I can use the construct operator to add an item to the beginning of a list: 1 : [2,3] [1,2,3] I tried making an example data type I found in the book and then playing with it: --in a file data BillingInfo = CreditCard Int String String | CashOnDelivery | Invoice Int deriving (Show) --in ghci $ let order_list = [Invoice 2345] $ order_list [Invoice 2345] $ let order_list = CashOnDelivery : order_list $ order_list [CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, CashOnDelivery, ...- etc... it just repeats forever, is this because it uses lazy evaluation? -- EDIT -- okay, so it is being pounded into my head that let order_list = CashOnDelivery:order_list doesn't add CashOnDelivery to the original order_list and then set the result to order_list, but instead is recursive and creates an infinite list, forever adding CashOnDelivery to the beginning of itself. Of course now I remember that Haskell is a functional language and I can't change the value of the original order_list, so what should I do for a simple "tack this on to the end (or beginning, whatever) of this list?" Make a function which takes a list and BillingInfo as arguments, and then return a list? -- EDIT 2 -- well, based on all the answers I'm getting and the lack of being able to pass an object by reference and mutate variables (such as I'm used to)... I think that I have just asked this question prematurely and that I really need to delve further into the functional paradigm before I can expect to really understand the answers to my questions... I guess what i was looking for was how to write a function or something, taking a list and an item, and returning a list under the same name so the function could be called more than once, without changing the name every time (as if it was actually a program which would add actual orders to an order list, and the user wouldn't have to think of a new name for the list each time, but rather append an item to the same list).

• Is it possible to create an Android Service that listens for hardware key presses?

  - by VoteBrian

  I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service". Does this mean it can't be done without rewriting Launcher, or is there something obvious I'm missing? public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect anyone but me to want this. I just think it'd be nice, for example, to use the camera button to wake the phone.

• error: expected ',' or '...' before numeric constant

  - by goldfrapp04

  Just a Qt Gui Application with QDialog as the Base Class, the simplest type you can expect. I've programmed on Qt for several times but this is the first time I meet this problem... I've added minimal code to the program, and here's the code in dialog.h (which is mostly automatically generated) #ifndef DIALOG_H #define DIALOG_H #include <QDialog> #include <QPixmap> #include "bmp.h" namespace Ui { class Dialog; } class Dialog : public QDialog { Q_OBJECT public: explicit Dialog(QWidget *parent = 0); ~Dialog(); private slots: void on_openButton_clicked(); private: Ui::Dialog *ui; BMP srcImage; QImage compressedImage[3]; }; #endif // DIALOG_H While I edit, the "public:" is underlined and says "unexpected token '('". When I try to build the program, it says in the line "Q_OBJECT", "error: expected ',' or '...' before numeric constant". I'm sure I've defined nothing related to it (to be exact, I defined an N and an n in file bmp.h, both are int). Any idea of what's wrong here? Thanks.

• Do new Apple SDKs patch previous releases?

  - by Francisco Garcia

  A new iPhone will be soon out there along a new iOS release. Sooner or later there will also be a Xcode upgrade with the SDK for iOS 6 Does Apple do any type of bugfix on previous SDKs or are bugfixes just solved on new releases? As an example: Core Data with iCloud still have some issues but it is getting better over time. Let's say I have an app that really depends on that combo. I would require iOS6, however not all users upgrade the handsets. Ideally an app compiled with a newer XCode release could patch some error on previous SDKs if the target is set to an older iOS release. Should I expect that a project compiled with future SDK releases to work better on devices running on older iOS versions? will be some SDKs bugfixes backported? I understand that there are some bugs that cannot be fixed without an iOS update on the client. Also that it is a lot of work (and unlikely) to backport bugfixes. I am just wondering what is the normal release policy of Apple.

• Html.RadioButton group defaulting to 0

  - by awrigley

  Hi A default value of 0 is creeping into a Surveys app I am developing, for no reason that I can see. The problem is as follows: I have a group of Html.RadioButtons that represent the possible values a user can choose to answer a survey question (1 == Not at all, 2 == A little, 3 == A lot). I have used a tinyint datatype, that does not allow null, to store the answer to each question. The view code looks like this: <ol class="SurveyQuestions"> <% foreach (SurveyQuestion question in Model.Questions) { string col = question.QuestionColumn; %> <li><%=question.QuestionText%> <ul style="float:right;" class="MultiChoice"> <li><%= Html.RadioButton(col, "1")%></li> <li><%= Html.RadioButton(col, "2")%></li> <li><%= Html.RadioButton(col, "3")%></li> </ul> <%= Html.ValidationMessage(col, "*") %> </li> <% } %> </ol> [Note on the above code:] Each survey has about 70 questions, so I have put the questions text in one table, and store the results in a different table. I have put the Questions into my form view model (hence Model.Questions); the questions table has a field called QuestionColumn that allows me to link up the answer table column to the question, as shown above (<%= Html.RadioButton(col, "1")%, etc) [/Note] However, when the user DOESN'T answer the question, the value 0 is getting inserted into the database column. As a result, I don't get what I expect, ie, a validation error. In no place have I stipulated a default value of 0 for the fields in the answers table. So what is happening? Any ideas?

• How to convert string with double high/wide characters to normal string [VC++6]

  - by Shaitan00

  My application typically recieves a string in the following format: " Item $5.69 " Some contants I always expect: - the LENGHT always 20 characters - the start index of the text always [5] - and most importantly the index of the DECIMAL for the price always [14] In order to identify this string correctly I validate all the expected contants listed above .... Some of my clients have now started sending the string with Doube-High / Double-Wide values (pair of characters which represent a single readable character) similar to the following: " Item $x80x90.x81x91x82x92 " For testing I simply scan the string character-by-character, compare char[i] and char[i+1] and replace these pairs with their corresponding single character when a match is found (works fine) as follows: [Code] for (int i=0; i < sData.length(); i++) { char ch = sData[i] & 0xFF; char ch2 = sData[i+1] & 0xFF; if (ch == '\x80' && ch2 == '\x90') zData.replace("\x80\x90", "0"); else if (ch == '\x81' && ch2 == '\x91') zData.replace("\x81\x91", "1"); else if (ch == '\x82' && ch2 == '\x92') zData.replace("\x82\x92", "2"); ... ... ... } [/Code] But the result is something like this: " Item $5.69 " Notice how this no longer matches my expectation: the lenght is now 17 (instead of 20) due to the 3 conversions and the decimal is now at index 13 (instead of 14) due to the conversion of the "5" before the decimal point. Ideally I would like to convert the string to a normal readable format keeping the constants (length, index of text, index of decimal) at the same place (so the rest of my application is re-usable) ... or any other suggestion (I'm pretty much stuck with this)... Is there a STANDARD way of dealing with these type of characters? Any help would be greatly appreciated, I've been stuck on this for a while now ... Thanks,

• call back function set by JS settimeout doesn't work in IE8....

  - by NAG

  <html <head <script function addEvent( obj, type, fn ) { if ( obj.attachEvent ) { obj['e'+type+fn] = fn; obj[type+fn] = function(){obj['e'+type+fn]( window.event );} obj.attachEvent( 'on'+type, obj[type+fn] ); } else obj.addEventListener( type, fn, false ); } </script </head <body <!-- HTML for example event goes here -- <div id="mydiv" style="border: 1px solid black; width: 100px; height: 100px; margin-top: 10px;"</div <script // Script for example event goes here addEvent(document.getElementById('mydiv'), 'contextmenu', function(event) { display_short('right-clicked (contextmenu)'); }); function display_short(str) { clearTimeout(); document.getElementById('mydiv').innerHTML = str; if (str != '') alert("hello"); setTimeout("display_short('abcd')", 1000); } </script </body </html Behaves diffrently in IE and FF when you right click on the div area. In ff display_short will be called for evry 1 sec eventhough you dont release right click but in IE it will not call display_short if you dont release right click. But i expect in IE it should call display_short for every 1 sec if you dont release also. Is there any solution for this?

• Does it ever make sense to make a fundamental (non-pointer) parameter const?

  - by Scott Smith

  I recently had an exchange with another C++ developer about the following use of const: void Foo(const int bar); He felt that using const in this way was good practice. I argued that it does nothing for the caller of the function (since a copy of the argument was going to be passed, there is no additional guarantee of safety with regard to overwrite). In addition, doing this prevents the implementer of Foo from modifying their private copy of the argument. So, it both mandates and advertises an implementation detail. Not the end of the world, but certainly not something to be recommended as good practice. I'm curious as to what others think on this issue. Edit: OK, I didn't realize that const-ness of the arguments didn't factor into the signature of the function. So, it is possible to mark the arguments as const in the implementation (.cpp), and not in the header (.h) - and the compiler is fine with that. That being the case, I guess the policy should be the same for making local variables const. One could make the argument that having different looking signatures in the header and source file would confuse others (as it would have confused me). While I try to follow the Principle of Least Astonishment with whatever I write, I guess it's reasonable to expect developers to recognize this as legal and useful.

• Ruby on Rails controller and architecture with cells

  - by dt

  I decided to try to use the cells plugin from rails: http://cells.rubyforge.org/community.html given that I'm new to Ruby and very used to thinking in terms of components. Since I'm developing the app piecemeal and then putting it together piece by piece, it makes sense to think in terms of components. So, I've been able to get cells working properly inside a single view, which calls a partial. Now, what I would like to be able to do (however, maybe my instincts need to be redirected to be more "Rails-y"), is call a single cell controller and use the parameters to render one output vs. another. Basically, if there were a controller like: def index params[:responsetype] end def processListResponse end def processSearchResponse end And I have two different controller methods that I want to respond to based on the params response type, where I have a single template on the front end and want the inner "component" to render differently depending on what type of request is made. That allows me to reuse the same front-end code. I suppose I could do this with an ajax call instead and just have it rerender the component on the front end, but it would be nice to have the option to do it either way and to understand how to architect Rails a bit better in the process. It seems like there should be a "render" option from within the cells framework to render to a certain controller or view, but it's not working like I expect and I don't know if I'm even in the ballpark. Thanks!

• Handling Apache Thrift list/map Return Types in C++

  - by initzero

  First off, I'll say I'm not the most competent C++ programmer, but I'm learning, and enjoying the power of Thrift. I've implemented a Thrift Service with some basic functions that return void, i32, and list. I'm using a Python client controlled by a Django web app to make RPC calls and it works pretty well. The generated code is pretty straight forward, except for list returns: namespace cpp Remote enum N_PROTO { N_TCP, N_UDP, N_ANY } service Rcon { i32 ping() i32 KillFlows() i32 RestartDispatch() i32 PrintActiveFlows() i32 PrintActiveListeners(1:i32 proto) list<string> ListAllFlows() } The generated signatures from Rcon.h: int32_t ping(); int32_t KillFlows(); int32_t RestartDispatch(); int32_t PrintActiveFlows(); int32_t PrintActiveListeners(const int32_t proto); int64_t ListenerBytesReceived(const int32_t id); void ListAllFlows(std::vector<std::string> & _return); As you see, the ListAllFlows() function generated takes a reference to a vector of strings. I guess I expect it to return a vector of strings as laid out in the .thrift description. I'm wondering if I am meant to provide the function a vector of strings to modify and then Thrift will handle returning it to my client despite the function returning void. I can find absolutely no resources or example usages of Thrift list< types in C++. Any guidance would be appreciated.

• libarchive reads too many chars when extracting a file

  - by ojreadmore

  I've written a C program to extract files from a tar archive using libarchive. I'd like to extract a file from this archive and print it to standard output. But I get extra characters. It's garbage, but it's from another file (possibly adjacent to it in the archive.) I expect output to end at </html>. Here is the code that reads this tar file. libarchive 2.8.3 compiled on mac os X 10.6.3. gcc 4.2 x86_64 ls -l vendar-definition.html gives me 1921 for the file size. And so shows tar tfv 0000.tar | grep vendar-definition.html. So reports the C output that states the file size. To me this seems correct. Two possibilities I can see for why my output is not as expected: 1. I've made a beginner's mistake or 2. multibyte characters in the archive files has something to do with it.

• VS2010 final does only link project on "rebuild all", not on "build changed"

  - by Sam

  I've just migrated a solution containing c++ and c# projects from VS2008 to VS2010 and got a strange problem. When I select "rebuild all", everything compiles and links as I would expect it to do. Then I change some c++ source file (just add a space), build the project, I get several thousands of linking errors like these: GDlgPackerListe.obj : error LNK2028: Nicht aufgelöstes Token (0A0000C7) ""public: bool __thiscall LList::Add(class LBString const &)" (?Add@LList@@$$FQAE_NABVLBString@@@Z)", auf das in Funktion ""public: virtual void __thiscall LRcPackerListe::HookRunReport(class LFortschritt &)" (?HookRunReport@LRcPackerListe@@$$FUAEXAAVLFortschritt@@@Z)" verwiesen wird.

When I hit "rebuild all" it recompiles and links without any errors or even warnings and produces a working exe. I'm using Visual Studio 2010 final (german edition). Whats going on here? Or, more important: how do I get the linker to work correctly??

• Problems with Threading in Python 2.5, KeyError: 51, Help debugging?

  - by vignesh-k

  I have a python script which runs a particular script large number of times (for monte carlo purpose) and the way I have scripted it is that, I queue up the script the desired number of times it should be run then I spawn threads and each thread runs the script once and again when its done. Once the script in a particular thread is finished, the output is written to a file by accessing a lock (so my guess was that only one thread accesses the lock at a given time). Once the lock is released by one thread, the next thread accesses it and adds its output to the previously written file and rewrites it. I am not facing a problem when the number of iterations is small like 10 or 20 but when its large like 50 or 150, python returns a KeyError: 51 telling me element doesn't exist and the error it points out to is within the lock which puzzles me since only one thread should access the lock at once and I do not expect an error. This is the class I use: class errorclass(threading.Thread): def __init__(self, queue): self.__queue=queue threading.Thread.__init__(self) def run(self): while 1: item = self.__queue.get() if item is None: break result = myfunction() lock = threading.RLock() lock.acquire() ADD entries from current thread to entries in file and REWRITE FILE lock.release() queue = Queue.Queue() for i in range(threads): errorclass(queue).start() for i in range(desired iterations): queue.put(i) for i in range(threads): queue.put(None) Python returns with KeyError: 51 for large number of desired iterations during the adding/write file operation after lock access, I am wondering if this is the correct way to use the lock since every thread has a lock operation rather than every thread accessing a shared lock? What would be the way to rectify this?

• iOS UIImageView dataWithContentsOfURL returning empty

  - by user761389

  I'm trying to display an image from a URL in a UIImageView and I'm seeing some very peculiar results. The bit of code that I'm testing with is below imageURL = @"http://images.shopow.co.uk/image/user_dyn/1073/32/32"; imageURL = @"http://images.shopow.co.uk/assets/profile_images/default/32_32/avatar-male-01.jpg"; NSURL *imageURLRes = [NSURL URLWithString:imageURL]; NSData *imageData = [NSData dataWithContentsOfURL:imageURLRes]; UIImage *image = [UIImage imageWithData:imageData]; NSLog(@"Image Data: %@", imageData); In it's current form I can see data in the output window which is what I'd expect. However if comment out the second imageURL so I'm referencing the first I'm getting empty data and therefore nil is being returned by imageWithData. What is possibly more confusing is that the first image is basically the same as the second but it's been through a PHP processing script. I'm nearly certain that it isn't the script that's causing the issue because if I use this instead imageURL = @"http://images.shopow.co.uk/image/product_dynimg/389620/32/32" the image is displayed and this uses the same image processing script. I'm struggling to find any difference in the images that would cause this to occur. Any help would be appreciated.

• jQuery $.ajax calls success handler when reuqest fails because of browser reloading

  - by Martin

  I have the following code: $.ajax({ type: "POST", url: url, data: sendable, dataType: "json", success: function(data) { if(customprocessfunc) customprocessfunc(data); }, error: function(XMLHttpRequest, textStatus, errorThrown){ // error handler here } }); I have a timer which makes AJAX requests often. If I do not receive anything in 'data', I show an error message to the user - it means, something wnet bad on the server. The problem is when user reloads the page while the AJAX call is in progress. I can see in the firebug that the AJAX call fails (URL is colored red and no HTTP status is displayed) so I expect that jQuery will stop the reuqest or at least go to the error handler. But it goes to the success handler and passes null in the 'data' variable. As a result, when user reloads the page, sometimes he can see my big red message about unknown error (because data is null). Is there any way to make jQuery abort the request on complete reloading all at least not to call my success function? I have no way to know in the success handler why the data is null - did it came empty from the server or the call was aborted because of reload.

• UIAlertView Will not show

  - by John

  I have a program that is requesting a JSON string. I have created a class that contains the connect method below. When the root view is coming up, it does a request to this class and method to load up some data for the root view. When I test the error code (by changing the URL host to 127.0.0.1), I expect the Alert to show. Behavior is that the root view just goes black, and the app aborts with no alert. No errors in debug mode on the console, either. Any thoughts as to this behavior? I've been looking around for hints to this for hours to no avail. Thanks in advance for your help. Note: the conditional for (error) is called, as well as the UIAlertView code. - (NSString *)connect:(NSString *)urlString { NSString *jsonString; UIApplication *app = [UIApplication sharedApplication]; app.networkActivityIndicatorVisible = YES; NSError *error = nil; NSURLResponse *response = nil; NSURL *url = [[NSURL alloc] initWithString:urlString]; NSURLRequest *req = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10]; NSData *_response = [NSURLConnection sendSynchronousRequest: req returningResponse: &response error: &error]; if (error) { /* inform the user that the connection failed */ //AlertWithMessage(@"Connection Failed!", message); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Oopsie!" message:@"Unable to connect! Try later, thanks." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; } else { jsonString = [[[NSString alloc] initWithData:_response encoding:NSUTF8StringEncoding] autorelease]; } app.networkActivityIndicatorVisible = NO; [url release]; return jsonString; }

• Running processes at different times stops events from working - C

  Hello, This is a question which follows on from my previously answered question here At first I assumed I had a problem with the way I was creating my events due to the handles for OpenEvent returning NULL, I have managed to find the real cause however I am not sure how to go about it. Basically I use Visual Studio to launch both Process A and B at the same time, in the past my OpenEvent handle wouldn't work due to Process A looking for the address of the event a fraction of a second before Process B had time to make it. My solution was to simply allow Process B to run before Process A, fixing the error. The problem I have now is that Process B now reads events from Process A and as you expect it too returns a null handle when trying to open the events from Process A. I am creating the events in WM_CREATE message of both processes, furthermore I also create a thread at the same time to open/read/act upon the events. It seems if I run them at the same time they don't get chance to see each other, alternatively if I run one before the other one of them misses out and can't open a Handle. Can anyone suggest a solution? Thanks.

• How can I introduce a regex action to match the first element in a Catalyst URI ?

  - by RET

  Background: I'm using a CRUD framework in Catalyst that auto-generates forms and lists for all tables in a given database. For example: /admin/list/person or /admin/add/person or /admin/edit/person/3 all dynamically generate pages or forms as appropriate for the table 'person'. (In other words, Admin.pm has actions edit, list, add, delete and so on that expect a table argument and possibly a row-identifying argument.) Question: In the particular application I'm building, the database will be used by multiple customers, so I want to introduce a URI scheme where the first element is the customer's identifier, followed by the administrative action/table etc: /cust1/admin/list/person /cust2/admin/add/person /cust2/admin/edit/person/3 This is for "branding" purposes, and also to ensure that bookmarks or URLs passed from one user to another do the expected thing. But I'm having a lot of trouble getting this to work. I would prefer not to have to modify the subs in the existing framework, so I've been trying variations on the following: sub customer : Regex('^(\w+)/(admin)$') { my ($self, $c, @args) = @_; #validation of captured arg snipped.. my $path = join('/', 'admin', @args); $c->request->path($path); $c->dispatcher->prepare_action($c); $c->forward($c->action, $c->req->args); } But it just will not behave. I've used regex matching actions many times, but putting one in the very first 'barrel' of a URI seems unusually traumatic. Any suggestions gratefully received.

• Formatting data for printing automatically

  - by 0bytes

  I have a requirement to retrieve data, format it to mimic an old request format we've used for years and then send it via IP address to any of a number of printers. Gathering the data and selecting the printer is no problem. I need to format the output for the printer and I'm just not sure what's best. The requirement is that the end users not have any interaction with the print request that's generated; only the intended recipients of the request job will know of the printed (& in a future release e-mailed) request. We also a requirement for a future update that we will have to incorporate into this solution an option to change the config in the DB so that each recipient site can choose printing or e-mail notification so I expect that I'll need to keep the control in a console app or webservice. I have the data and I can send it to the printers or generate an HTML-formatted e-mail easily; I just need to format it for the autoprinting. I don't think SSRS will help because I don't know of a way to designate a printer when running a report. Thanks for all help & suggestions.

• How to systematically generate images from data?

  - by adamvickers

  I work for a performing arts nonprofit. We have seating charts for each of the theaters we work with; each seating chart shows the number of sections, the shape of each section, and the number of rows in each section. We'd like to create dynamic seating charts based on this info. We'd like them to look/feel kinda like this: http://www.fansnap.com/tickets/177754-on. But the tricky part is we'd like to be able to store all the info about each theater (the section names, shape/size of each section, and number of rows in each section) as data and then build a system that reads this data and uses it to create a dynamic map. I'm a life-long web developer, but I don't have have any experience with a difficult graphics problem like this. I realize it's a complex problem and I don't expect anyone to give me a complete answer here, but I would love direction on where I should be looking for more info. Is what I'm describing possible? Does this sort of technique have a name? Where can I learn more about how to accomplish this? What software should I use? Any info would be helpful.

• Dataset holds a table called "Table", not the table I pass in?

  - by dotnetdev

  Hi, I have the code below: string SQL = "select * from " + TableName; using (DS = new DataSet()) using (SqlDataAdapter adapter = new SqlDataAdapter()) using (SqlConnection sqlconn = new SqlConnection(connectionStringBuilder.ToString())) using (SqlCommand objCommand = new SqlCommand(SQL, sqlconn)) { sqlconn.Open(); adapter.SelectCommand = objCommand; adapter.Fill(DS); } System.Windows.Forms.MessageBox.Show(DS.Tables[0].TableName); return DS; However, every time I run this code, the dataset (DS) is filled with one table called "Table". It does not represent the table name I pass in as the parameter TableName and this parameter does not get mutated so I don't know where the name Table comes from. I'd expect the table to be the same as the tableName parameter I pass in? Any idea why this is not so? EDIT: Important fact: This code needs to return a dataset because I use the dataRelation object in another method, which is dependent on this, and without using a dataset, that method throws an exception. The code for that method is: DataRelation PartToIntersection = new DataRelation("XYZ", this.LoadDataToTable(tableName).Tables[tableName].Columns[0], // Treating the PartStat table as the parent - .N this.LoadDataToTable("PartProducts").Tables["PartProducts"].Columns[0]); // 1 // PartsProducts (intersection) to ProductMaterial DataRelation ProductMaterialToIntersection = new DataRelation("", ds.Tables["ProductMaterial"].Columns[0], ds.Tables["PartsProducts"].Columns[1]); Thanks
