  • What's the fastest way to get CRUD over CGI on a database handle in Perl?

    - by mithaldu
    TL;DR: Want to write CGI::CRUD::Simple (a minimalist interface module for CGI::CRUD), but I want to check first if i overlooked a module that already does that. I usually work with applications that don't have the niceties of having frameworks and such already in place. However, a while ago i found myself in a situation where i was asking myself: "Self, i have a DBI database handle and a CGI query object, isn't there a module somewhere that can use this to give me some CRUD so i can move on and work on other things instead of spending hours writing an interface?" A quick survey on CPAN gave me: CGI::Crud Catalyst::Plugin::CRUD Gantry::Plugins::CRUD Jifty::View::Declare::CRUD CatalystX::CRUD Catalyst::Controller::CRUD CatalystX::CRUD::REST Catalyst::Enzyme Now, I didn't go particularly in-depth when looking at these modules, but, safe the first one, they all seem to require the presence of some sort of framework. Please tell me if i was wrong and i can just plug any of those into a barebones CGI script. CGI::CRUD seemed to do exactly what i wanted, although it did insist on being used through a rather old and C-like script that must be acquired on a different site and then prodded in various ways and manners to produce something useful. I went with that and found that it works pretty neat and that it should be rather easy to write a simple and easy-to-use module that provides a very basic [dbh, cgi IN]-[html OUT] interface to it. However, as my previous survey was rather short and i may have been hasty in dismissing modules or missed others, i find myself wondering whether that would only be duplication of work already done. As such i ponder the question in the title. PS: I tend to be too short in some of my explanations and make too many assumptions that others think about things similarly as me, resulting in leaving out critical details. If you find yourself wondering just what exactly I am thinking about when i say CRUD, please poke me in comments and I'll amend the question.

  • Database design problem: intermediate table between 2 tables may end up with too many results.

    - by SK.
    I have to design a database to handle forms. Basically, a form needs to go through (exactly) 7 people, one by one. Each person can either agree or decline a form. If one declines, the chain stops and the following people don't even get notified that there is a form. Right now I have thought of those 3 tables: FORM, PERSON, and RESPONSE inbetween. However, my first solution sounds too heavy because each form could have up to 7 responses. Here we are with the table inbetween. That means that each successful form has 7 rows in the table RESPONSE. Here we have the responding information directly inside the form. It looks ugly but at least keeps everything as singular as possible. On the bad side I can't track the response dates, but I don't think it is crucial for that matter. What is your opinion on this? I feel like both of them are wrong and I don't know how to fix that. If that matters, I'll be using Oracle 9.

  • Producer/consumer system using database (MySql), is this feasible?

    - by johnrl
    Hi all. I need to use something to coordinate my system with several consumers/producers each running on different machines with different operating systems. I have been researching on using MySql to do this, but it seems ridiculously difficult. My requirements are simple: I want to be able to add or remove consumers/producers at any time and thus they should not depend on each other at all. Naturally a database would separate the two nicely. I have been looking at Q4M message queuing plugin for MySql but it seems complicated to use: I have to recompile it every time I upgrade MySql (can this really be true?) because when I try to install it on Ubuntu 9.10 with MySql 5.1.37 it says "Can't open shared library 'libqueue_engine.so' (errno: 0 API version for STORAGE ENGINE plugin is too different)". There is no precompiled version for MySql 5.1.37 apparently. Also what if I want to run MySql on my windows machine, then I can't rely on this plugin as it only seems to run on Linux and OSX?? I really need some input on how to construct my system best possible.

  • Increase file upload size limit in iis6

    - by JustFoo
    Is there any other place besides the metabase.xml file where the file upload size can be modified? I am currently running a staging server with IIS6 and it is setup to allow uploading of files up to 20mb. This works perfectly fine. I have a new production server where I am trying to setup this same available size limit. So I edited the metabase.xml file and set it to 20971520. Then I restarted IIS and that didn't work. So I then restarted the entire server, that also didn't work. I can upload files around 2mb so it is definitely allowing file sizes larger then the standard 200kb default size. I try uploading a 5mb file and my upload.aspx page completely crashes. Is it possible there is something else I need to configure? The production server is located on a server farm, could there be some limits set on there end? Thanks

  • static arrays defined with unspecified size, empty brackets?

    - by ahmadabdolkader
    For the C++ code fragment below: class Foo { int a[]; // no error }; int a[]; // error: storage size of 'a' isn't known void bar() { int a[]; // error: storage size of 'a' isn't known } why isn't the member variable causing an error too? and what is the meaning of this member variable? I'm using gcc version 3.4.5 (mingw-vista special) through CodeBlocks 8.02. On Visual Studio Express 2008 - Microsoft(R) C/C++ Optimizing Compiler 15.00.30729.01 for 80x86, I got the following messages: class Foo { int a[]; // warning C4200: nonstandard extension used : zero-sized array in struct/union - Cannot generate copy-ctor or copy-assignment operator when UDT contains a zero-sized array }; int a[]; void bar() { int a[]; // error C2133: 'a' : unknown size } Now, this needs some explaination too.

  • Database design for a media server containing movies, music, tv and everything in between?

    - by user364114
    In the near future I am attempting to design a media server as a personal project. MY first consideration to get the project underway is architecture, it will certainly be web based but more specifically than that I am looking for suggestions on the database design. So far I am considering something like the following, where I am using [] to represent a table, the first text is the table name to give an idea of purpose and the items within {} would be fields of the table. Also not, fid is functional id referencing some other table. [Item {id, value/name, description, link, type}] - this could be any entity, single song or whole music album, game, movie - almost see this as a recursive relation, ie. a song is an item but an album that song is part of is also an item or for example a tv season is an item, with multiple items being tv episodes [Type {id, fid, mime type, etc}] - file type specific information - could identify how code handles streaming/sending this item to a user [Location {id, fid, path to file?}] [Users {id, username, email, password, ...? }] - user account information [UAC {id, fid, acess level}] - i almost feel its more flexible to seperate access control permissions form the user accounts themselves [ItemLog {id, fid, fid2, timestamp}] - fid for user id, and fid2 for item id - this way we know what user access what when [UserLog {id, fid, timestamp}] -both are logs for access, whether login or last item access [Quota {id, fid, cap}] - some sort of way to throttle users from queing up the entire site and letting it download ... Suggestions or comments are welcome as the hope is that this project will be a open source project once some code is laid out.

  • ImageView doesn't rescale Image to selected size

    - by Buni
    I'm using a ImageView with a fixed size for adding an icon to a menu. In my application, I use it a lot of times, but on this ImageView the Layout Params seem to not work. Unlike the others ImageViews, in this case, I'm using a template directly, but I think that's not the problem. <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="1dp" android:layout_height="1dp" android:scaleType="fitCenter" android:src="@drawable/ic_menu_moreoverflow_normal_holo_dark" android:contentDescription="ICON" /> Its been used in code as follows. ImageView iview =(ImageView) View.inflate(context, R.layout.icon, null); Theoretically, It should resize automatically the image, however, the images continues with the original size, although the size was 1dp. Where is the problem? Thanks a lot!

  • J2ME Reduce Image color-depth/ Compress Image size

    - by updateraj
    Hi, I need to transmit the image from the mobile phone to the server. I am able to reduce the image screen size but not the memory size. I understand i have to deal with the color depth. J2ME does not seem to offer any scaling method which is available in J2SE: image rescaled = image.getScaledInstance(thumbWidth, thumbHeight, Image.SCALE_AREA_AVERAGING); BufferedImage biRescaled = toBufferedImage(rescaled, thumbWidth, thumbHeight, BufferedImage.TYPE_INT_RGB); How i would i tackle this ? I would like to reduce the image memory size before i transmit to the server. Thank you

  • Database design and foreign keys: Where should they be added in related tables?

    - by Carvell Fenton
    I have a relatively simple subset of tables in my database for tracking something called sessions. These are academic sessions (think offerings of a particular program). The tables to represent a sessions information are: sessions session_terms session_subjects session_mark_item_info session_marks All of these tables have their own primary keys, and are like a tree, in that sessions have terms, terms have subjects, subjects have mark items, etc. So each on would have at least its "parent's" foreign key. My question is, design wise is it a good idea to include the sessions primary key in the other tables as a foreign key to easily select related session items, or is that too much redundency? If I include the session foreign key (or all parent foreign keys from tables up the heirarchy) in all the tables, I can easily select all the marks for a session. As an example, something like SELECT mark FROM session_marks WHERE sessionID=... If I don't, then I would have to combine selects with something like WHERE something IN (SELECT... Which approach is "more correct" or efficient? Thanks in advance!

  • Is there a standard for storing normalized phone numbers in a database?

    - by Eric Z Beard
    What is a good data structure for storing phone numbers in database fields? I'm looking for something that is flexible enough to handle international numbers, and also something that allows the various parts of the number to be queried efficiently. [Edit] Just to clarify the use case here: I currently store numbers in a single varchar field, and I leave them just as the customer entered them. Then, when the number is needed by code, I normalize it. The problem is that if I want to query a few million rows to find matching phone numbers, it involves a function, like where dbo.f_normalizenum(num1) = dbo.f_normalizenum(num2) which is terribly inefficient. Also queries that are looking for things like the area code become extremely tricky when it's just a single varchar field. [Edit] People have made lots of good suggestions here, thanks! As an update, here is what I'm doing now: I still store numbers exactly as they were entered, in a varchar field, but instead of normalizing things at query time, I have a trigger that does all that work as records are inserted or updated. So I have ints or bigints for any parts that I need to query, and those fields are indexed to make queries run faster.

  • How to develop for iphone application about "retrieving database file on web"?

    - by coverboy
    Hi...all experts! I'm a newbie to iphone developer. Well, currently, I'm developing iphone for Location Based Service. That application need to have these functions. 1. hierarchical tree-view on navigation bar. 2. list up page 3. detail page for example, Let's say. I have top category like "Restaurant, Hotel, Gift Shop" Second level "New York, LA, London,....." Third Level displays all Data with 1 photo. Fourth Level displays Detail of that "Restaurant or Hotel, Gift shop, ..." So, My Only Interest is "How to retrieve the data from remote database server. not using iphone local one." Because, that locations, and shops should be updated frequently, (you know some shops closed, new shops opens.) So, till now, I figured out that using XML to retrieve data. However, using XML is the most effective way to implement? Is there any other way to accomplish this work? You know, transferring XML data via 3G Network is really slow. XML file have more bytes than plist file. I'm currently a beginner of iphone development. So, please help me find a right way!! And, one more question, if I use xml way. Is it possible to Paging? (First page 10 lists up, below that more button...) well, you might guess each category have hundreds of shops!!

  • [Database] How to model this one-to-one relation?

    - by pbean
    I have several entities which respresent different types of users who need to be able to log in to a particular system. Additionally, they have different types of information associated with them. For example: a "general user", which has an e-mail address and "admin user", which has a workstation number (note that this a hypothetical case). Both entities also share common properties like first name, surname, address and telephone number. Finally, they naturally need to have a (unique) user name and a password to log in. In the application, the user just has to fill in his user name and password, and the functionality of the application changes slightly according to the type of the user. You can imagine that the username needs to be unique for this work. How should I model this effectively? I can't just create two tables, because then I can't force a unique constaint on the user name. I also can't put them all in just one table, because they have different types of specific information associated to them. I think I might need 3 seperate tables, one for "users" (with user name and password), one for the "general users" and another one for the "admin users", but how would the relations between these work? Or is there another solution? (By the way, the target DBMS is MySQL, so I don't think generalization is supported in the database system itself).

  • Increasing the JVM maximum heap size for memory intensive applications

    - by Alceu Costa
    I need to run a Java memory intensive application that uses more than 2GB, but I am having problems to increase the heap maximum size. So far, I have tried the following approaches: Setting the -Xmx parameter, e.g. -Xmx3000m. This approaches fails at the creation of the JVM. From what I've googled, it looks like that -Xmx must be less than 2GB. Using the -XX:+AggressiveHeap option. When I try this approach I get an 'Not enough memory' error that tells that the heap size is 1273.4 MB, even though my computer has 8GB of memory. Is there another approach that I can try to increase the maximum heap size of the JVM? Here's a summary of the computer specs: OS: Windows 7 (64 bit) Processor: Intel Core i7 (2.66 GHz) Memory: 8 GB

  • .NET framework 4 total application deployment size

    - by kzen
    After watching in horror as the .NET framework 3.5 SP1 bloated to whopping 231 MB I was amazed to see that .NET Framework 4 Full (x86) is only 35 MB and client profile just 29 MB. My question is if .NET Framework 4 is in any way dependent on previous versions of the framework being installed on the client machine or if my users will have to download only 29 (or 35) MB if I develop a Winforms or WPF desktop application in VS 2010 targeting .NET Framework version 4.0? Edit: Wikipedia concurs with the answers: Some developers have expressed concerns about the large size of .NET framework runtime installers for end-users. The size is around 54 MB for .NET 3.0, 197 MB for .NET 3.5, and 250 MB for .NET 3.5 SP1 (while using web installer the typical download for Windows XP is around 50 MB, for Windows Vista - 20 MB). The size issue is partially solved with .NET 4 installer (x86 + x64) being 54 MB and not embedding full runtime installation packages for previous versions.

  • c arrays: setting size dynamically?

I am trying to set the size of the array using a variable but I am getting an error: Storage size of 'array' isn't constant !! 01 int bound = bound*4; 02 static GLubyte vertsArray[bound]; I have noticed that when I replace bounds (within the brackets on line 02) with the number say '20', the program would run with no problems. But I am trying to set the size of the array dynamically ... Any ideas why I am getting this error ? thanks much,

  • Dynamically update Font Size of application with a single trigger in WPF

    - by Sukan
    I have an application which has different font sizes for different controls say Button: 10, TextBlock : 12 etc. I want to give options to the user where he can select any one of the below say Normal , Small, Big, Bigger. Suppose one selects "small" I would want to decrease every distinct font size by 2. If "Big", I would want to increase every font size by 2. I hope we can do this using converter sending actual font size as parameter and render as per the selected choice if I am not wrong. What will be the best option. Sorry if my doubt is absurd or silly. Thank you.

  • HTML table with fixed cells size

    - by misha-moroshko
    I have an HTML table which has equally divided rows and columns. I would like each cell to be of a fixed size, say 40px width and 30px height. When I change the size of the browser window, the cells size changes also. How can I prevent it ? I would expect to see the scroll bars if browser's window become too small. Is that right to set the height and the width of the cell in pixels ? Thanks !

  • Maximum executable size on the iPhone?

    - by Sirp
    Is there a maximum size of executables or executables + shared objects on the iPhone? I've been developing an app that has been crashing on startup or early in execution with SIGSYS. Removing code from the program has helped, though structuring data so the code is simply not executed does not. This could be memory corruption, of some kind, however when I compiled with -Os rather than -O2 or -O3 the size of my executable goes down from 5.15MB to 3.60MB and the application runs perfectly. I also have a bunch of libraries I use, of course. I'm wondering, is there a limit on the size of executable code on the iPhone? Or am I just 'getting lucky' and masking memory corruption when I use -Os?

  • Question about using an access database as a resource file in Visual Studio.

    - by user354303
    Hi I am trying to embed a Microsoft Access database file into my Class assembly DLL. I want my code to reference the resource file and use it with a ADODB.Connection object. Any body know a simpler way, or an easier way? Or what is wrong with my code, when i added the resource file it added me dataset definitions, but i have no idea what to do with those. The connection string I am trying below is from an automatically generated app.config. I did add the item as a resource... using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using ConsoleApplication1.Resources;//SPPrinterLicenses using System.Data.OleDb; using ADODB; using System.Configuration; namespace ConsoleApplication1 { class SharePointPrinterManager { public static bool IsValidLicense(string HardwareID) { OleDbDataAdapter da = new OleDbDataAdapter(); DataSet ds = new DataSet(); ADODB.Connection adoCn = new Connection(); ADODB.Recordset adoRs = new Recordset(); //**open command below fails** adoCn.Open( @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Resources\SPPrinterLicenses.accdb;Persist Security Info=True", "", "", 1); adoRs.Open("Select * from AllWorkstationLicenses", adoCn, ADODB.CursorTypeEnum.adOpenForwardOnly, ADODB.LockTypeEnum.adLockReadOnly, 1); da.Fill(ds, adoRs, "AllworkstationLicenses"); adoCn.Close(); DataTable dt = new DataTable(); //ds.Tables. return true; } } }

  • Streaming data to the browser as a file of unknown size

    - by Sir Psycho
    I have some data which is queried from the database and I'd like to send it to the client as a csv file. The file size varies each time due to the fact that the DB data returned can be of any size. Instead of saving this file to the hard disk, I'd like to send it to the browser at the same time it's being processed into a CSV by my algorithm. Response.Write seems useless. For some reason, the file download dialog is only displayed once my processing is finished. This seems odd as I'm writting all my output to the Response.Output stream. I have downloaded files on the web before where the filesize is not known and the browser just keeps on downloading. Is there any way to achieve this? The following stackoverflow thread did not offer any good advise. http://stackoverflow.com/questions/873995/asp-net-downloading-large-files-of-unknown-size Thanks

  • Perl: Fastest way to get directory (and subdirs) size on unix - using stat() at the moment

    - by ivicas
    I am using Perl stat() function to get the size of directory and it's subdirectories. I have a list of about 20 parent directories which have few thousand recursive subdirs and every subdir has few hundred records. Main computing part of script looks like this: sub getDirSize { my $dirSize = 0; my @dirContent = <*>; my $sizeOfFilesInDir = 0; foreach my $dirContent (@dirContent) { if (-f $dirContent) { my $size = (stat($dirContent))[7]; $dirSize += $size; } elsif (-d $dirContent) { $dirSize += getDirSize($dirContent); } } return $dirSize; } The script is executing for more than one hour and I want to make it faster. I was trying with the shell du command, but the output of du (transfered to bytes) is not accurate. And it is also quite time consuming. I am working on HP-UNIX 11i v1.

  • How to show useful error messages from a database error callback in Phonegap?

    - by Magnus Smith
    Using Phonegap you can set a function to be called back if the whole database transaction or the individual SQL statement errors. I'd like to know how to get more information about the error. I have one generic error-handling function, and lots of different SELECTs or INSERTs that may trigger it. How can I tell which one was at fault? It is not always obvious from the error message. My code so far is... function get_rows(tx) { tx.executeSql("SELECT * FROM Blah", [], lovely_success, statement_error); } function add_row(tx) { tx.executeSql("INSERT INTO Blah (1, 2, 3)", [], carry_on, statement_error); } function statement_error(tx, error) { alert(error.code + ' / ' + error.message); } From various examples I see the error callback will be passed a transaction object and an error object. I read that .code can have the following values: UNKNOWN_ERR = 0 DATABASE_ERR = 1 VERSION_ERR = 2 TOO_LARGE_ERR = 3 QUOTA_ERR = 4 SYNTAX_ERR = 5 CONSTRAINT_ERR = 6 TIMEOUT_ERR = 7 Are there any other properties/methods of the error object? What are the properties/methods of the transaction object at this point? I can't seem to find a good online reference for this. Certainly not on the Phonegap website!

  • NSPredicate aggregate function [SIZE] gives 'unsupported function expression' error

    iOS 4: I have entities in Core Data (using SQLite, which is a requirement) of: Request Response (which has a property personId) Revision Relationships are: Request <-- Revision Request <-- Response Revision <-- Response (e.g. each request may have many responses; each request/response pair may have many revisions) I'm trying to do a predicate to get all Responses with a given personId that have zero Revisions. Using: (personId == %d) && (Request.Revision[SIZE] == 0) in my predicate string gives me a runtime exception "Unsupported function expression Request.Revision[SIZE]" The documentation seems pretty sparse on aggregate functions, only noting that they exist, but with no syntax or examples. Not sure if it's my syntax or if the SIZE function really isn't supported in iOS.
