  • HTML input text box vs CakePHP Automagic Form Elements

    - by kwokwai
    Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

  • Why does Custom UITableViewCell *sometimes* cause an NSInvalidArgumentException?

    - by Wayne Hartman
    I have created a custom UITableViewCell, but when I dequeue the cell, sometimes it throws an NSInvalidArgumentException: [UITableViewCell nameLabel]: unrecognized selector sent to instance 0x3b4e7f0 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UITableViewCell nameLabel]: unrecognized selector sent to instance 0x3b4e7f0' Now, my custom UITableViewCell does have an attribute nameLabel, so I am confused why it is throwing this error. Below is the code I use to dequeue the cell: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; CTMenuItemVO* key = [[[self retrieveCartItems] allKeys] objectAtIndex:row]; NSNumber* quantity = [[self retrieveCartItems] objectForKey:key]; static NSString* SectionsTableIdentifier = @"SectionsTableIdentifier2"; OrderItemCell* cell = (OrderItemCell*)[tableView dequeueReusableCellWithIdentifier: SectionsTableIdentifier]; if (cell == nil) { NSArray* topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"OrderItemCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if ([currentObject isKindOfClass:[UITableViewCell class]]) { cell = (OrderItemCell*) currentObject; break; } } } cell.nameLabel.text = key.Name; cell.qtyLabel.text = [quantity stringValue]; return cell; }

  • Checking if a boolean column is true in MySQL/Rails

    - by Pygmalion
    Rails and MySQL: I have a table with several boolean columns representing tags. I want to find all the rows for which a specific one of these columns is 'true' (or I guess in the case of MySQL, '1'). I have the following code in my view. @tag = params[:tag] @supplies = Supply.find(:all, :conditions=>["? IS NOT NULL and ? !=''", @tag, @tag], :order=>'name') The @tag is being passed in from the url. Why is it then that I am instead getting all of my @supplies (i.e. every row) rather than just those that are true for the column for @tag. Thanks!

  • Visual Studio 2010 element names for theming

    - by Anthony Potts
    I am trying to figure out what the element name for the tooltip is in Visual studio so that I can change the style using the extension found here. Anyone know what that is? I am using the default theme which seems to have a white to light grey gradient on it. This is less than optimal since the text for the functions are also white. In a more general question (and perhaps better), is there anything that maps the names as they are found in the theme to where they are in the IDE.

  • Find files in a folder using Java

    - by Sii
    Hello, I'm new here so be kind to my stupidity :) What I need to do if Search a folder say C:\example I then need to go through each file and check to see if it matches a few start characters so if files start temp****.txt tempONE.txt tempTWO.txt So if the file starts with temp and has an extension .txt I would like to then put that file name into a File file = new File("C:/example/temp***.txt); so I can then read in the file, the loop then needs to move onto the next file to check to see if it meets as above. I hope this makes sense, thanks for taking the time to view this I do apperciate it :)

  • best way to prgram php and mysql query

    - by air
    most of times in our pages we need to print only 1 field value of table in loop. for example <?php for($i=1;$i<=mysql_num_rows($result);$i++) { echo $row['name']; $sql1="select industry from table_industry where profid='".$row['prof']."'"; $result1=mysql_query($sql1); $row1=mysql_fetch_array($result1); echo $row1['industry']; ?> } ?> above is one PHP code just for example where we think that $row['prof'] carry value of profession ID and we print profession of each person. for example we have 5000+ record in table and above loop will execute for 5000+ times what will be the best way to print value of industry field from table table_industry Same code which i write above ? any other php code suggestion for faster execution and less use of resources? Thanks

  • Different ways to specify libraries to gcc/g++

    - by abigagli
    I'd be curious to understand if there's any substantial difference in specifying libraries (both shared and static) to gcc/g++ in the two following ways (CC can be g++ or gcc) CC -o output_executable /path/to/my/libstatic.a /path/to/my/libshared.so source1.cpp source2.cpp ... sourceN.cpp vs CC -o output_executable -L/path/to/my/libs -lstatic -lshared source1.cpp source2.cpp ... sourceN.cpp I can only see a major difference being that passing directly the fully-specified library name would make for a greater control in choosing static or dynamic versions, but I suspect there's something else going on that can have side effects on how the executable is built or will behave at runtime, am I right? Andrea.

  • moving EDMX file System.Data.MetadataException: Unable to load the specified metadata resource.

    - by Dani
    I have a ASP.NET MVC 2 project. I've created edmx file on the class library project that holds the model. now I've created another class library called it shared and moved the edmx file over there. resolved some issues, everything compiles, but it can't find the connection string resource at runtime. I've copied the ConnectionString part of the Web.Config to the main file, the old class library app.config file and the new class library app.config file. Still get this error: System.Data.MetadataException: Unable to load the specified metadata resource. Line 75: public myProjdb() : base("name=myProjdb", "MyProjdb") in the MyProj.Designer.cs file. Any Idea how to resolve this issue ? Is there a better way to store connection string data ?

  • Collectable<T> serialization, Root Namespaces on T in .xml files.

    - by Stacey
    I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

  • "Winamp style" spectrum analyzer

    - by cvb
    I have a program that plots the spectrum analysis (Amp/Freq) of a signal, which is preety much the DFT converted to polar. However, this is not exactly the sort of graph that, say, winamp (right at the top-left corner), or effectively any other audio software plots. I am not really sure what is this sort of graph called (if it has a distinct name at all), so I am not sure what to look for. I am preety positive about the frequency axis being base two exponential, the amplitude axis puzzles me though. Any pointers?

  • UML and Documenting Simple Diagrams

    - by Jason
    As part of a rewrite of an old Java application into C#, I'm writing an actual Software Design Specification. A problem I run into is when a method is too simple to bother with a Sequence Diagram (it doesn't interact with other objects). As an example, I have a simple POJO called Item, containing the following method: public String getCategoryKey() { StringBuffer value = new StringBuffer("s-"); value.append(this.getModelID()); value.append("-c"); return value; } The purpose and the algorithm for the method needs to be documented. However, a sequence diagram is overkill. How would others document it? (I take no credit/blame for the given method, it's very old code and the author "forgot" to put their name in the Javadoc).

  • How to grab the lines AFTER a matched line in python

    - by toofly
    Hi All, I am an amateur using Python on and off for some time now. Sorry if this is a silly question, but I was wondering if anyone knew an easy way to grab a bunch of lines if the format in the input file is like this: " Heading 1 Line 1 Line 2 Line 3 Heading 2 Line 1 Line 2 Line 3 " I won't know how many lines are after each heading, but I want to grab them all. All I know is the name, or a regular expression pattern for the heading. The only way I know to read a file is the "for line in file:" way, but I don't know how to grab the lines AFTER the line I'm currently on. Hope this makes sense, and thanks for the help!

  • Why is it not saying I won?

    - by Itachi
    This is my if statement... The buttons show up like this: This is my if statement if((buttons[3].getName()=="x" && buttons[6].getName()=="x" && buttons[9].getText()=="x")||(buttons[2].getName()=="x" && buttons[5].getName()=="x" && buttons[8].getName()=="x")|| ((buttons[1].getName()=="x") && (buttons[4].getName()=="x") && (buttons[7].getName()=="x"))){ JOptionPane.showMessageDialog(null,"X Wins"); } So if I select the 1st, 4th and 7th buttons (the left most 3 buttons) why does it not say "X Wins"? As a sidenote, yes the buttons should have the name "x"

  • Adapting methods which return true/false

    - by James P.
    What's the best practise when adapting C-style functions which return a true/false to Java? Here's a simple method to illustrate where the problem lies. public static boolean fileNameEndsWithExtension( String filename, String fileExtension) { return filename.endsWith( fileExtension ); } Note that there's probably a more elegant way of filtering files (feel free to comment on this). Anyway, if filename is a null value, does one: Return a false if filename is null? If so, how does one go about distinguishing between the case where filename is null and the case where the String or file name doesn't end with a given file extension? Change the return type to the wrapper class Boolean which allows a null value. Throw an Exception and force the programmer to make sure that a null value is never passed to the method? Use another solution?

  • How do I submit really big amounts of data to a form?

    - by William Calleja
    I have an HTML from that's posting a really big amount of data which is eventually being saved into an SQL Server 2005, the form is as follows: <form name="frmForm" method="post" action="saveData.aspx"> the target page takes the content of a control within the form and saves it to the database through a normal SQL insert statement. However only a portion of the data is being saved. The field in the database is an ntext. Should I use a different field? Or is something happening while I'm transferring from one page to another? Or even still there's something happening when I'm sending the really big SQL statement through c# in saveData.aspx?

  • Is SHA sufficient for checking file duplication? (sha1_file in PHP)

    - by wag2639
    Suppose you wanted to make a file hosting site for people to upload their files and send a link to their friends to retrieve it later and you want to insure files are duplicated where we store them, is PHP's sha1_file good enough for the task? Is there any reason to not use md5_file instead? For the frontend, it'll be obscured using the original file name store in a database but some additional concerns would be if this would reveal anything about the original poster. Does a file inherit any meta information with it like last modified or who posted it or is this stuff based in the file system? Also, is using a salt frivolous since security in regards of rainbow table attack mean nothing to this and the hash could later be used as a checksum? One last thing, scalability? initially, it's only going to be used for small files a couple of megs big but eventually... Edit 1: The point of the hash is primarily to avoid file duplication, not to create obscurity.

  • Would you hire a foreigner ? [closed]

    - by user229999
    Hi! I'd like to dedicate this question (hope it's not a subjective) especially to people who own their companies. Would you (and why) hire a foreigner, which experience is documented in CV and portfolio, which can communicate in english (with grammar mistakes, but still)? I am writing in the name of all these guys looking for great opportunities abroad, living in countries which do not give you any opportunities at all. Is it real, to be hired like a programmer (PHP, Ruby, Python, C#) in country like UK, USA, Nederland, Sweeden or even Germany, if you're a foreigner? Please response in two categories: a) foreigner with engineer degree, zend certificate, few open source projects b) foreigner without any degree, with nice portfolio, and few big projects created Also, does First Certificate in English aka FCE matter for you ?

  • Using different versions of the same assembly.

    - by AngryHacker
    I have a project where I simultaneously must use reports built in ActiveReports 2 and ActiveReports 6. Overall, it works ok, but some of the helper assemblies use the same name. For instance, to be able to export to PDF, both versions use an assembly called ActiveReports.PdfExport.dll. The corresponding assemblies are different, of course. Note that I don't access the ActiveReports.PdfExport.dll directly - this is handled by the ActiveReports runtime. I can't find a way to include both of them into the project. Is there a way? Is GAC the answer?
