  • Placing & deleting element(s) from a object (stack)

    - by Chris
    Hello, Initialising 2 stack objects: Stack s1 = new Stack(), s2 = new Stack(); s1 = 0 0 0 0 0 0 0 0 0 0 (array of 10 elements wich is empty to start with) top:0 const int Rows = 10; int[] Table = new int[Rows]; public void TableStack(int[] Table) { for (int i=0; i < Table.Length; i++) { } } My question is how exactly do i place a element on a stack (push) or take a element from the stack (pop) as the following: Push: s1.Push(5); // s1 = 5 0 0 0 0 0 0 0 0 0 (top:1) s1.Push(9); // s1 = 5 9 0 0 0 0 0 0 0 0 (top:2) Pop: int number = s1.Pop(); // s1 = 5 0 0 0 0 0 0 0 0 0 0 (top:1) 9 got removed Do i have to use get & set, and if so how exactly do i implent this with a array? Not really sure what to exactly use for this. Any hints highly appreciated. The program uses the following driver to test the Stack class (wich cannot be changed or modified): public void ExecuteProgram() { Console.Title = "StackDemo"; Stack s1 = new Stack(), s2 = new Stack(); ShowStack(s1, "s1"); ShowStack(s2, "s2"); Console.WriteLine(); int getal = TryPop(s1); ShowStack(s1, "s1"); TryPush(s2, 17); ShowStack(s2, "s2"); TryPush(s2, -8); ShowStack(s2, "s2"); TryPush(s2, 59); ShowStack(s2, "s2"); Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s1, 2 * i); ShowStack(s1, "s1"); } Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s2, i * i); ShowStack(s2, "s2"); } Console.WriteLine(); for (int i = 1; i <= 6; i++) { getal = TryPop(s2); //use number ShowStack(s2, "s2"); } }/*ExecuteProgram*/ Regards.

  • how escape quotes when inserting into database in PHP

    - by Mauro74
    Hi all, I'm quite new to PHP so sorry if sounds such an easy problem... :) I'm having an error message when inserting content which contains quotes into my db. here's what I tried trying to escape the quotes but didn't work: $con = mysql_connect("localhost","xxxx","xxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $nowdate = date('d-m-Y') $title = sprintf($_POST[title], mysql_real_escape_string($_POST[title])); $body = sprintf($_POST[body], mysql_real_escape_string($_POST[body])); $sql="INSERT INTO articles (title, body, date) VALUES ('$title','$body','$nowdate'),"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } header('Location: index.php'); Could you provide any solution please? Thanks in advance. Mauro

  • Finding gaps (missing records) in database records using SQL

    - by Tony_Henrich
    I have a table with records for every consecutive hour. Each hour has some value. I want a T-SQL query to retrieve the missing records (missing hours, the gaps). So for the DDL below, I should get a record for missing hour 04/01/2010 02:00 AM (assuming date range is between the first and last record). Using SQL Server 2005. Prefer a set based query. DDL: CREATE TABLE [Readings]( [StartDate] [datetime] NOT NULL, [SomeValue] [int] NOT NULL ) INSERT INTO [Readings]([StartDate], [SomeValue]) SELECT '20100401 00:00:00.000', 2 UNION ALL SELECT '20100401 01:00:00.000', 3 UNION ALL SELECT '20100401 03:00:00.000', 45

  • prevent multiple login with same login credentials in php

    - by shinod
    My website has premium videos, for which users have to pay to watch it. I am sending a random user name and password to the user's email id when the payment is completed. Then I want to assure no more than one user use that login credentials simultaneously. For that I use a login_status column in database table with login credentials and change it to 1 when one user login and change to 0 when user log out. But the problem is, if the user close browser or network connection loss may happened will not update database. Then login_will be 1 undefinitely and no one can use that login credentials again. Is there any idea to accomplish my task?

  • NSKeyedUnarchiver chokes when trying to unarchive more than one object

    - by ajduff574
    We've got a custom matrix class, and we're attempting to archive and unarchive an NSArray containing four of them. The first seems to get unarchived fine (we can see that initWithCoder is called once), but then the program simply hangs, using 100% CPU. It doesn't continue or output any errors. These are the relevant methods from the matrix class (rows, columns, and matrix are our only instance variables): -(void)encodeWithCoder:(NSCoder*) coder { float temp[rows * columns]; for(int i = 0; i < rows; i++) { for(int j = 0; j < columns; j++) { temp[columns * i + j] = matrix[i][j]; } } [coder encodeBytes:(const void *)temp length:rows*columns*sizeof(float) forKey:@"matrix"]; [coder encodeInteger:rows forKey:@"rows"]; [coder encodeInteger:columns forKey:@"columns"]; } -(id)initWithCoder:(NSCoder *) coder { if (self = [super init]) { rows = [coder decodeIntegerForKey:@"rows"]; columns = [coder decodeIntegerForKey:@"columns"]; NSUInteger * len; *len = (unsigned int)(rows * columns * sizeof(float)); float * temp = (float * )[coder decodeBytesForKey:@"matrix" returnedLength:len]; matrix = (float ** )calloc(rows, sizeof(float*)); for (int i = 0; i < rows; i++) { matrix[i] = (float*)calloc(columns, sizeof(float)); } for(int i = 0; i < rows *columns; i++) { matrix[i / columns][i % columns] = temp[i]; } } return self; } And this is really all we're trying to do: NSArray * weightMatrices = [NSArray arrayWithObjects:w1,w2,w3,w4,nil]; [NSKeyedArchiver archiveRootObject:weightMatrices toFile:@"weights.archive"]; NSArray * newWeights = [NSKeyedUnarchiver unarchiveObjectWithFile:@"weights.archive"]; What's driving us crazy is that we can archive and unarchive a single matrix just fine. We've done so (successfully) with a matrix many times larger than these four combined.

  • Processing file uploads before object is saved

    - by Dominic Rodger
    I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

  • Object C casting

    - by ct2k7
    Hi, I'm trying to cast this statement: [self handError:noConnectionError]; basically, this statement is in a class, which is not the app delegate, but is the .m file of a view, specifically a view after uitableview, which contains its own uiviewtable. The warning that statement gives me is that the error produced may not be apparent to the UIView (view control container).

  • Problem displaying Vertex Buffer Object (OpenGL and Obj-C)

    - by seaworthy
    Hey, I am having a problem displaying or loading a buffer with an array of vertices. I know that array works fine because I am able to render it using a loop and a glVertex command. I can't figure out what's wrong. Your insight is highly appreciated. GLuint vboId; glGenBuffers( 1, &vboId ); glBindBuffer( GL_ARRAY_BUFFER, vboId); glBufferData( GL_ARRAY_BUFFER, count*sizeof( GLfloat ),array,GL_STATIC_DRAW_ARB ); glBindBuffer( GL_ARRAY_BUFFER, 0 ); printf("%d\n",count); glEnableClientState( GL_VERTEX_ARRAY ); glBindBuffer( GL_ARRAY_BUFFER, vboId ); glVertexPointer( 3, GL_FLOAT, 0, 0 ); glDisableClientState( GL_VERTEX_ARRAY ); printf("vboId: [%hd]",vboId); glDeleteBuffers(1, &vboId); Help?

  • make website page get news articles from feeds

    - by Andy
    Hi, I would like to start publishing some news articles from time to time. An option would be to create a new web page for every article but this sounds like it can be done easier. For instance I noticed clear channel uses some kind of feed, like: http://www.z100.com/cc-common/news/sections/newsarticle.html?feed=104650&article=7011404 I don't know what it means and how it works but looks like a nice way to get the article from some kind of database I guess? Does someone knows how this works, or some other way to create new articles etc, some dynamical functionality for instance to generate links to the articles and get the right article from a database for example. thanks!

  • Browser Helper Object doesnot get loaded in IE8

    - by velusbits
    I have a BHO, which i can see it as enabled in Add On's list. But it does not get loaded when i start my IE on the Win2k8 R2 machines(64 bit). I have disabled IE Enhanced security as well but no help. The same BHO gets loaded in other machines. The registry details under (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects & HKEY_CLASSES_ROOT\Wow6432Node\CLSID) seem to be fine. Is there any setting that disables BHO from actually getting loaded?

  • GWT Date Picker Format problem when saving a java date through hibernate in postgresql

    - by Noor
    Hi, I am using Java Date and Hibernate which is then being saved in the database (Postgresql). I am not that good in hibernate Part of the Mapping File <property name="DateOfBirth" type="java.util.Date"> <column name="DATEOFBIRTH" /> </property> I am using GWT Date picker Short date format i.e. yyyy-MM-dd. I am getting the value from the date picker using View.getUserDateOfBirth().getValue() But when I am saving the date 2010-11-30 into the datebase it is saving it as 2010-11-30 00:00:00 instead of 2010-11-30 So, I want it to be saved in the database as in this format 2010-11-30?? I have many things such timestamp but i not being able to configure it. I think this part <property name="DateOfBirth" type="java.util.Date"> <column name="DATEOFBIRTH" /> </property> should be changed but I do not know what to change

  • Does MSDeploy support website and database upgrades?

    - by Samuel Jack
    I've just been reading about MSDeploy, the new website deployment tool from Microsoft. I'm developing an installer for a webapplication and a webservice to be used for our off-the-shelf product. I have a couple of questions that I couldn't find obvious answers to. Does MSDeploy have robust support for upgrading websites after the initial deployment? I can see MSDeploy has good support for the initial deployment of databases. But does it have support for upgrading schemas whilst preserving the current data? Links addressing these specific questions would be good.

  • List<object>.RemoveAll - How to create an appropriate Predicate

    - by CJM
    This is a bit of noob question - I'm still fairly new to C# and generics and completely new to predicates, delegates and lamda expressions... I have a class 'Enquiries' which contains a generic list of another class called 'Vehicles'. I'm building up the code to add/edit/delete Vehicles from the parent Enquiry. And at the moment, I'm specifically looking at deletions. From what I've read so far, it appears that I can use Vehicles.RemoveAll() to delete an item with a particular VehicleID or all items with a particular EnquiryID. My problem is understanding how to feed .RemoveAll the right predicate - the examples I have seen are too simplistic (or perhaps I am too simplistic given my lack of knowledge of predicates, delegates and lambda expressions). So if I had a List<Of Vehicle> Vehicles where each Vehicle had an EnquiryID, how would I use Vehicles.RemoveAll() to remove all vehicles for a given EnquiryID? I understand there are several approaches to this so I'd be keen to hear the differences between approaches - as much as I need to get something working, this is also a learning exercise. As an supplementary question, is a Generic list the best repository for these objects? My first inclination was towards a Collection, but it appears I am out of date. Certainly Generics seem to be preferred, but I'm curious as to other alternatives. Thanks

  • how to implement class with collection of string/object pairs so that an object can be returned with

    - by matti
    The values in a file are read as string and can be double, string or int or maybe even lists. An example file: DatabaseName=SomeBase Classes=11;12;13 IntValue=3 //this is required! DoubleValue=4.0 I was thinking something like this: public static T GetConfigValue(string cfgName) { // here we just return for example the value which could // be List[int] if parameter cfgName='Classes' // and LoadConfig was called with Dictionary containing // keyvaluepair 'Classes' / typeof(List[int]) } public static bool LoadConfig(Dictionary reqSettings, Dictionary optSettings) { foreach (KeyValuePair kvPair in reqSettings) { if (ReadCheckAndStore(kVPair, true)) return false; } foreach (KeyValuePair kvPair in reqSettings) { if (ReadCheckAndStore(kVPair, false)) return false; } return true; } private static bool ReadCheckAndStore(KeyValuePair kVPair, bool isRequired) { if (!ReadValue(kVPair.Key, out confValue) && isRequired) //req. IntValue !found return false; //here also have to test if read value is wanted type. //and if yes store to collection. } Thanks a lot & BR! -Matti PS. Additional issue is default values for optional settings. It's not elegant to pass them to LoadConfig in separate Dictionary, but that is an other issue...

  • A database of questions with unambiguous numeric answers.

    - by dreeves
    I (and co-hackers) are building a sort of trivia game inspired by this blog post: http://messymatters.com/calibration. The idea is to give confidence intervals and learn how to be calibrated (when you're "90% sure" you should be right 90% of the time). We're thus looking for, ideally, thousands of questions with unambiguous numerical answers. Also, they shouldn't be too boring. There are a lot of random statistics out there -- eg, enclosed water area in different countries -- that would make the game mind-numbing. Things like release dates of classic movies are more interesting (to most people). Other interesting ones we've found include Olympic records, median incomes for different professions, dates of famous inventions, and celebrity ages. Scraping things like above, by the way, was my reason for asking this question: http://stackoverflow.com/questions/2611418/scrape-html-tables So, if you know of other sources of interesting numerical facts (in a parsable form) I'm eager for pointers to them. Thanks!
