  • Software Requirement Specifications for Web Applications

    - by illuminatedtiger
    Hi guys, I'm looking for some guidance/books to read when it comes to creating a software requirement specification for a web application. For inspiration I have read some spec documents for desktop based applications. The documents I have read capture a systems functional requirements in use cases which tend to be rather data oriented with use cases centered around the various CRUD operations the application is intended to perform. I like this structure however I'm finding it rather difficult to marry it to what my web application needs to do, mostly reading data as opposed to manipulating it. I've had a go at writing some use cases however they all tend to boil down to "Search for item", "Change view of search results" or "User selects facet to refine search results". This doesn't sound quite right to me and makes me wonder if I'm going about this the right way. Are there planning differences between web based and desktop based applications?

  • Problem using structured data with sproxy-generated proxy c++ class

    - by Odrade
    I am attempting to communicate structured data types between a Visual C++ client application and an ASP.NET web service. I'm am having issues whenever any parameter or return type is not a basic type (e.g. string, int, float, etc). To illustrate the issue, I created the following ASP.NET web service: namespace TestWebService { [WebService(Namespace = "http://localhost/TestWebService")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public TestData StructuredOutput() { TestData td = new TestData(); td.data = 1729; return td; } } public class TestData { public int data; } } To consume the service, I created a dirt-simple Visual C++ client in VS2005. I added a web reference to the project, which caused sproxy to generate a proxy class for me. With the generated header properly included, I attempted to invoke the service like this: int _tmain(int argc, _TCHAR* argv[]) { CoInitialize(NULL); Service1::CService1 ws; Service1::TestData td; HRESULT hr = ws.StructuredOutput(&td); //data is returned as expected CoUninitialize(); return 0; } // crashes here with access violation The call to StructuredOutput returns the data as expected, but an access violation occurs on destruction of the CService1 object. The access violation is occurring here (from atlsoap.h): void UninitializeSOAP() { if (m_spReader.p != NULL) { m_spReader->putContentHandler(NULL); //access violation m_spReader.Release(); } } I see the same behavior when using a TestData object as an input parameter, or when using any other structured data types as input or output. When I use basic types for input/output from the web service I do not experience these errors. Any ideas about why this might be happening? Is sproxy screwing something up, or am I? NOTE: I'm aware of gSOAP and the wsdl2h tool, but those aren't freely available for commercial use (and nobody here is going to buy a license). I am open to alternatives for generating the c++ proxy, as long as they are free for commercial use.

  • Drawing only part of a

    - by Ben Reeves
    ..Continued on from my previous question I have a 320*480 RGB565 framebuffer which I wish to draw using OpenGL ES 1.0 on the iPhone. - (void)setupView { glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, (int[4]){0, 0, 480, 320}); glEnable(GL_TEXTURE_2D); } // Updates the OpenGL view when the timer fires - (void)drawView { // Make sure that you are drawing to the current context [EAGLContext setCurrentContext:context]; //Get the 320*480 buffer const int8_t * frameBuf = [source getNextBuffer]; //Create enough storage for a 512x512 power of 2 texture int8_t lBuf[2*512*512]; memcpy (lBuf, frameBuf, 320*480*2); //Upload the texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 512, 512, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, lBuf); //Draw it glDrawTexiOES(0, 0, 1, 480, 320); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } If I produce the original texture in 512*512 the output is cropped incorrectly but other than that looks fine. However using the require output size of 320*480 everything is distorted and messed up. I'm pretty sure it's the way I'm copying the framebuffer into the new 512*512 buffer. I have tried this routine int8_t lBuf[512][512][2]; const char * frameDataP = frameData; for (int ii = 0; ii < 480; ++ii) { memcpy(lBuf[ii], frameDataP, 320); frameDataP += 320; } Which is better, but the width appears to be stretched and the height is messed up. Any help appreciated.

  • Uncaught exception while using xdebug

    - by rich97
    I'm not too great with xdebug so forgive me if this is a stupid question. But I installed it on a separate machine and it performed some magic for me like formating my var_dump() output and catching any uncaught exceptions. It also fails to format the stack traces, outputting plain text which is extremely hard to read. As I am learning the Lithium PHP Framework I am required to use php5.3, on my other machine I compiled from the source but on this machine I'm using the precompiled packages from dotdeb.org. As far as I can tell the only difference is that this is a slightly newer version of php and it comes with the Suhosin patch. The other odd thing is that the xdebug functions such as xdebug_var_dump() work, aside from poor formatting. This is an Ubuntu machine, so I don't know if it could be anything to do with the dotdep packages, but I have installed xdebug through pecl, the downloadable tarball and from the SVN repository. But to no avail. You can see my php.ini and output of php -i in the following gist. I copied php.ini from /etc/php5/apache2/php.ini over to /etc/php5/cli/php.ini so php -i should reflect my apache setup. http://gist.github.com/391675 Any help is appreciated. Rich

  • Creating 3DES key from bytes

    - by AO
    I create a triple DES key from the a byte array ("skBytes") but when calling getEncoded on the triple DES key ("sk") and comparing it to the byte array, they differ! They are almost the same if you look at the console output, though. How would I create a triple DES key that is exactly as "skBytes"? byte[] skBytes = {(byte) 0x41, (byte) 0x0B, (byte) 0xF0, (byte) 0x9B, (byte) 0xBC, (byte) 0x0E, (byte) 0xC9, (byte) 0x4A, (byte) 0xB5, (byte) 0xCE, (byte) 0x0B, (byte) 0xEA, (byte) 0x05, (byte) 0xEF, (byte) 0x52, (byte) 0x31, (byte) 0xD7, (byte) 0xEC, (byte) 0x2E, (byte) 0x75, (byte) 0xC3, (byte) 0x1D, (byte) 0x3E, (byte) 0x61}; DESedeKeySpec keySpec = new DESedeKeySpec(skBytes); SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DESede"); SecretKey sk = keyFactory.generateSecret(keySpec); for(int i = 0; i < skBytes.length; i++) { System.out.println("(sk.getEncoded()[i], skBytes[i]) = (" + sk.getEncoded()[i] +", " + skBytes[i] + ")"); } Console output: (sk.getEncoded()[i], skBytes[i]) = (64, 65) (sk.getEncoded()[i], skBytes[i]) = (11, 11) (sk.getEncoded()[i], skBytes[i]) = (-15, -16) (sk.getEncoded()[i], skBytes[i]) = (-101, -101) (sk.getEncoded()[i], skBytes[i]) = (-68, -68) (sk.getEncoded()[i], skBytes[i]) = (14, 14) (sk.getEncoded()[i], skBytes[i]) = (-56, -55) (sk.getEncoded()[i], skBytes[i]) = (74, 74) (sk.getEncoded()[i], skBytes[i]) = (-75, -75) (sk.getEncoded()[i], skBytes[i]) = (-50, -50) (sk.getEncoded()[i], skBytes[i]) = (11, 11) (sk.getEncoded()[i], skBytes[i]) = (-22, -22) (sk.getEncoded()[i], skBytes[i]) = (4, 5) (sk.getEncoded()[i], skBytes[i]) = (-17, -17) (sk.getEncoded()[i], skBytes[i]) = (82, 82) (sk.getEncoded()[i], skBytes[i]) = (49, 49) (sk.getEncoded()[i], skBytes[i]) = (-42, -41) (sk.getEncoded()[i], skBytes[i]) = (-20, -20) (sk.getEncoded()[i], skBytes[i]) = (47, 46) (sk.getEncoded()[i], skBytes[i]) = (117, 117) (sk.getEncoded()[i], skBytes[i]) = (-62, -61) (sk.getEncoded()[i], skBytes[i]) = (28, 29) (sk.getEncoded()[i], skBytes[i]) = (62, 62) (sk.getEncoded()[i], skBytes[i]) = (97, 97)

  • Strategy Pattern with Type Reflection affecting Performances ?

    - by Aurélien Ribon
    Hello ! I am building graphs. A graph consists of nodes linked each other with links (indeed my dear). In order to assign a given behavior to each node, I implemented the strategy pattern. class Node { public BaseNodeBehavior Behavior {get; set;} } As a result, in many parts of the application, I am extensively using type reflection to know which behavior a node is. if (node.Behavior is NodeDataOutputBehavior) workOnOutputNode(node) .... My graph can get thousands of nodes. Is type reflection greatly affecting performances ? Should I use something else than the strategy pattern ? I'm using strategy because I need behavior inheritance. For example, basically, a behavior can be Data or Operator, a Data behavior can IO, Const or Intermediate and finally an IO behavior can be Input or Output. So if I use an enumeration, I wont be able to test for a node behavior to be of data kind, I will need to test it to be [Input, Output, Const or Intermediate]. And if later I want to add another behavior of Data kind, I'm screwed, every data-testing method will need to be changed.

  • Cakephp how to use Set Class to make an assoc array?

    - by michael
    I have the output array from a $Model-find() query which also pulls data from a hasMany relationship: Array( [Parent] => Array ( [id] => 1 ) [Child] => Array ( [0] => Array ( [id] => aaa [score] => 3 [src] => stage6/tn~4bbb38cc-0018-49bf-96a9-11a0f67883f5.jpg [parent_id] => 1 ) [1] => Array ( [id] => bbb [score] => 5 [src] => stage0/tn~4bbb38cc-00ac-4b25-b074-11a0f67883f5.jpg [parent_id] => 1 ) [2] => Array ( [id] => ccc [score] => 2 [src] => stage4/tn~4bbb38cc-01c8-44bd-b71d-11a0f67883f5.jpg [parent_id] => 1 ) ) ) I'd like to transform this output into something like this, where the child id is the key to additional child attributes: Array( [aaa] => Array ( [score] => 3 [src] => stage6/tn~4bbb38cc-0018-49bf-96a9-11a0f67883f5.jpg ) [bbb] => Array ( [score] => 5 [src] => stage0/tn~4bbb38cc-00ac-4b25-b074-11a0f67883f5.jpg ) [ccc] => Array ( [score] => 2 [src] => stage4/tn~4bbb38cc-01c8-44bd-b71d-11a0f67883f5.jpg ) } Is there an easy way to use Set::extract, Set::combine, Set::insert, etc. to do this efficiently? I cannot figure it out.

  • Windows-1251 file inside UTF-8 site?

    - by Spoonk
    Hello everyone Masters Of Web Delevopment :) I have a piece of PHP script that fetches last 10 played songs from my winamp. This script is inside file (lets call it "lastplayed.php") which is included in my site with php include function inside a "div". My site is on UTF-8 encoding. The problem is that some songs titles are in Windows-1251 encoding. And in my site they displays like "??????"... Is there any known way to tell to this div with included "lastplayed.php" in it, to be with windows-1251 encoding? Or any other suggestions? P.S: The file with fetching script a.k.a.

  • Optimizing processing and management of large Java data arrays

    - by mikera
    I'm writing some pretty CPU-intensive, concurrent numerical code that will process large amounts of data stored in Java arrays (e.g. lots of double[100000]s). Some of the algorithms might run millions of times over several days so getting maximum steady-state performance is a high priority. In essence, each algorithm is a Java object that has an method API something like: public double[] runMyAlgorithm(double[] inputData); or alternatively a reference could be passed to the array to store the output data: public runMyAlgorithm(double[] inputData, double[] outputData); Given this requirement, I'm trying to determine the optimal strategy for allocating / managing array space. Frequently the algorithms will need large amounts of temporary storage space. They will also take large arrays as input and create large arrays as output. Among the options I am considering are: Always allocate new arrays as local variables whenever they are needed (e.g. new double[100000]). Probably the simplest approach, but will produce a lot of garbage. Pre-allocate temporary arrays and store them as final fields in the algorithm object - big downside would be that this would mean that only one thread could run the algorithm at any one time. Keep pre-allocated temporary arrays in ThreadLocal storage, so that a thread can use a fixed amount of temporary array space whenever it needs it. ThreadLocal would be required since multiple threads will be running the same algorithm simultaneously. Pass around lots of arrays as parameters (including the temporary arrays for the algorithm to use). Not good since it will make the algorithm API extremely ugly if the caller has to be responsible for providing temporary array space.... Allocate extremely large arrays (e.g. double[10000000]) but also provide the algorithm with offsets into the array so that different threads will use a different area of the array independently. Will obviously require some code to manage the offsets and allocation of the array ranges. Any thoughts on which approach would be best (and why)?

  • Using GNU Octave FFT functions

    - by CFP
    Hello world! I'm playing with octave's fft functions, and I can't really figure out how to scale their output: I use the following (very short) code to approximate a function: function y = f(x) y = x .^ 2; endfunction; X=[-4096:4095]/64; Y = f(X); # plot(X, Y); F = fft(Y); S = [0:2047]/2048; function points = approximate(input, count) size = size(input)(2); fourier = [fft(input)(1:count) zeros(1, size-count)]; points = ifft(fourier); endfunction; Y = f(X); plot(X, Y, X, approximate(Y, 10)); Basically, what it does is take a function, compute the image of an interval, fft-it, then keep a few harmonics, and ifft the result. Yet I get a plot that is vertically compressed (the vertical scale of the output is wrong). Any ideas? Thanks!

  • Searching Database by Arbitrary Date in PHP

    - by jverdi
    Suppose you have a messaging system built in PHP with a MySQL database backend, and you would like to support searching for messages using arbitrary date strings. The database includes a messages table, with a 'date_created' field represented as a datetime. Examples of the arbitrary date strings that would be accepted by the user should mirror those accepted by strtotime. For the following examples, searches performed on March 21, 2010: "January 26, 2009" would return all messages between 2009-01-26 00:00:00 and 2009-01-27 00:00:00 "March 8" would return all messages between 2010-03-08 00:00:00 and 2010-01-26 00:00:00 "Last week" would return all messages between 2010-03-14 00:00:00 and 2010-03-21 018:25:00 "2008" would return all messages between 2008-01-01 00:00:00 and 2008-12-31 00:00:00 I began working with date_parse, but the number of variables grew quickly. I wonder if I am re-inventing the wheel. Does anyone have a suggestion that would work either as a general solution or one that would capture most of the possible input strings?

  • Question on Win32 LogonUser API and the Logon Type

    - by Lalit_M
    We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

  • Read from one large file and write to many (tens, hundreds, or thousands) files in Java?

    - by Rudiger
    I have a large-ish file (4-5 GB compressed) of small messages that I wish to parse into approximately 6,000 files by message type. Messages are small; anywhere from 5 to 50 bytes depending on the type. Each message starts with a fixed-size type field (a 6-byte key). If I read a message of type '000001', I want to write append its payload to 000001.dat, etc. The input file contains a mixture of messages; I want N homogeneous output files, where each output file contains only the messages of a given type. What's an efficient a fast way of writing these messages to so many individual files? I'd like to use as much memory and processing power to get it done as fast as possible. I can write compressed or uncompressed files to the disk. I'm thinking of using a hashmap with a message type key and an outputstream value, but I'm sure there's a better way to do it. Thanks!

  • Add Ellipsis to a Path in a WinForms Program without Win32 API call (revisited)

    - by casterle
    I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

  • Reducing Time Complexity in Java

    - by Koeneuze
    Right, this is from an older exam which i'm using to prepare my own exam in january. We are given the following method: public static void Oorspronkelijk() { String bs = "Dit is een boodschap aan de wereld"; int max = -1; char let = '*'; for (int i=0;i<bs.length();i++) { int tel = 1; for (int j=i+1;j<bs.length();j++) { if (bs.charAt(j) == bs.charAt(i)) tel++; } if (tel > max) { max = tel; let = bs.charAt(i); } } System.out.println(max + " keer " + let); } The questions are: what is the output? - Since the code is just an algorithm to determine the most occuring character, the output is "6 keer " (6 times space) What is the time complexity of this code? Fairly sure it's O(n²), unless someone thinks otherwise? Can you reduce the time complexity, and if so, how? Well, you can. I've received some help already and managed to get the following code: public static void Nieuw() { String bs = "Dit is een boodschap aan de wereld"; HashMap<Character, Integer> letters = new HashMap<Character, Integer>(); char max = bs.charAt(0); for (int i=0;i<bs.length();i++) { char let = bs.charAt(i); if(!letters.containsKey(let)) { letters.put(let,0); } int tel = letters.get(let)+1; letters.put(let,tel); if(letters.get(max)<tel) { max = let; } } System.out.println(letters.get(max) + " keer " + max); } However, I'm uncertain of the time complexity of this new code: Is it O(n) because you only use one for-loop, or does the fact we require the use of the HashMap's get methods make it O(n log n) ? And if someone knows an even better way of reducing the time complexity, please do tell! :)

  • can the python wave module accept StringIO object

    - by user368005
    i'm trying to use the wave module to read wav files in python. whats not typical of my applications is that I'm NOT using a file or a filename to read the wav file, but instead i have the wav file in a buffer. And here's what i'm doing import StringIO buffer = StringIO.StringIO() buffer.output(wav_buffer) file = wave.open(buffer, 'r') but i'm getting a EOFError when i run it...

  • How do I include the proper XML / HTML definitions in a file generated by XSL?

    - by Colen
    As I understand it, you need to include the following code at the top of your HTML files to make sure they're parsed properly: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> ... I'm generating an html file by transforming an XML file using an XSL file. This is going to be done using the MSXML tool, which produces a standard HTML file as output. If I just do this: <xsl:template match="/"> <html> ... Everything is fine. But if I do this: <xsl:template match="/"> <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> ... I get the error XML Parsing Error: XML or text declaration not at start of entity in Firefox, or Cannot have a DOCTYPE declaration outside of a prolog. in IE. Presumably this is because the parser is finding two How do I make the browser a) understand that I am using proper strict HTML, and b) make sure those declarations are put into the HTML output file that MSXML generates?

  • How to trigger a postback using JQuery Droppable plugin ?

    - by Sandeep K Ram
    Hi, This is my script for the draggable and droppable <script type="text/javascript"> $(function() { $(".Source li").draggable({ appendTo: "body", helper: "clone", revert: "invalid" }); $(".Destination ").droppable({ activeClass: "ui-state-default", hoverClass: "ui-state-hover", accept: ".Source li", drop: function(event, ui) { $(this).find(".placeholder").remove(); $("#Hf1").val(ui.draggable.text()); $("#TxtItemId").val($("#Hf1").val()); } }); }); </script> Now I want to access the value of the "TxtItemId" control in the code-behind through a postback. How do I go about doing this ? BTW, this is for a scenario where a person will drag an item from a panel into a shopping cart and I need to capture the Id of the dropped item and trigger a postback after the drop to update the quantity of that item in the cart.

  • JSP: How can I still get the code on my error page to run, even if I can't display it?

    - by Josh Hinman
    I've defined an error-page in my web.xml: <error-page> <exception-type>java.lang.Exception</exception-type> <location>/error.jsp</location> </error-page> In that error page, I have a custom tag that I created. The tag handler for this tag e-mails me the stacktrace of whatever error occurred. For the most part this works great. Where it doesn't work great is if the output has already begun being sent to the client at the time the error occurs. In that case, we get this: SEVERE: Exception Processing ErrorPage[exceptionType=java.lang.Exception, location=/error.jsp] java.lang.IllegalStateException I believe this error happens because we can't redirect a request to the error page after output has already started. The work-around I've used is to increase the buffer size on particularly large JSP pages. But I'm trying to write a generic error handler that I can apply to existing applications, and I'm not sure it's feasible to go through hundreds of JSP pages making sure their buffers are big enough. Is there a way to still allow my stack trace e-mail code to execute in this case, even if I can't actually display the error page to the client?

  • jQuery.clone() IE problem

    - by mofle
    I'm have some that uses jQuery.clone() to get the html of a page and then add it to a pre tag. It works correctly in Firefox and Chrome, but nothing happens in IE: <!DOCTYPE html> <html> <head> <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <meta charset=utf-8 /> <title>JS Bin</title> <!--[if IE]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script> $(function(){ $('button').click(function(){ var $clone = $('html').clone(); $('#output').text($clone.html()); }); }); </script> <style> article, aside, figure, footer, header, hgroup, menu, nav, section { display: block; } </style> </head> <body> <button>run test</button> <pre id="output"></pre> </body> </html> Is there any know bug with IE that prevents this, or am I doing something wrong? (I need to clone it because I'm doing some changes to it before outputting it)

  • Fastest way to modify a decimal-keyed table in MySQL?

    - by javanix
    I am dealing with a MySQL table here that is keyed in a somewhat unfortunate way. Instead of using an auto increment table as a key, it uses a column of decimals to preserve order (presumably so its not too difficult to insert new rows while preserving a primary key and order). Before I go through and redo this table to something more sane, I need to figure out how to rekey it without breaking everything. What I would like to do is something that takes a list of doubles (the current keys) and outputs a list of integers (which can be cast down to doubles for rekeying). For example, input {1.00, 2.00, 2.50, 2.60, 3.00} would give output {1, 2, 3, 4, 5). Since this is a database, I also need to be able to update the rows nicely: UPDATE table SET `key`='3.00' WHERE `key`='2.50'; Can anyone think of a speedy algorithm to do this? My current thought is to read all of the doubles into a vector, take the size of the vector, and output a new vector with values from 1 => doubleVector.size. This seems pretty slow, since you wouldn't want to read every value into the vector if, for instance, only the last n/100 elements needed to be modified. I think there is probably something I can do in place, since only values after the first non-integer double need to be modified, but I can't for the life of me figure anything out that would let me update in place as well. For instance, setting 2.60 to 3.00 the first time you see 2.50 in the original key list would result in an error, since the key value 3.00 is already used for the table.
