  • Trouble with arraylist and stack

    - by helloman
    I am having trouble starting out this program, I am suppose to write a program that will create an ArrayList, asking the user for 10 numbers. Then this will be put into the Array. Then after the list is made navigate it and if a number is even remove it from the ArrayList and copy it to a stack of integers. import java.io.* ; import java.util.*; public class Test { public static void main(String[] args){ Scanner input = new Scanner (System.in); ArrayList<Integer> integers = new ArrayList<Integer>(); System.out.print ("Enter Number: \n"); for (int i = 0; i < 10; i++){ integers.add(input.nextInt()); } for (int i = 0; i < 10 ; i++){ if (i %2==0) } } }

  • Formatting numbers by tokens with php

    - by Adam D
    I'm looking for a way to format numbers using "tokens". This needs to be conditional (for the first few leading characters). Example: <?php $styles=array('04## ### ###','0# #### ####','13# ###','1800 ### ###'); format_number(0412345678); /*should return '0412 345 678'*/ format_number(0812345678); /*should return '08 1234 5678'*/ format_number(133622); /*should return '133 622'*/ format_number(1800123456); /*should return '1800 123 456'*/ ?> Incase you haven't guessed, my use of this is to format Australian phone numbers, dependent on their 'type'. I have a PHP function that does this, but it is ~114 lines and contains a lot of repeated code. Can anyone help?

  • Need some explanation about MS Ajax using PageMethods

    - by Ahmed Said
    I have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured "WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON." Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example: function OnRequestComplete(result, userContext, methodName) { var Person = eval('(' + result + ')'); alert(Person.Forename); alert(Person.Surname); } So is the first technique is correct? or what?

  • Adding nil to NSMutableArray

    - by ayanonagon
    I am trying to create a NSMutableArray by reading in a .txt file and am having trouble setting the last element of the array to nil. NSString *filePath = [[NSBundle mainBundle] pathForResource:@"namelist" ofType:@"txt"]; NSString *data = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; NSArray *list = [data componentsSeparatedByString:@"\n"]; NSMutableArray *mutableList = [[NSMutableArray alloc] initWithArray:list]; I wanted to use NSMutableArray's function addObject, but that will not allow me to add nil. I also tried: [mutableList addObject:[NSNull null]]; but that does not seem to work either. Is there a way around this problem?

  • problems, custum wrap (class) around PDO, doesn't work

    - by Knarf
    DB::construct(); $STH = DB::prepare('INSERT INTO users (username, password, email, activationkey) VALUES (?, UNHEX(?), ?, ?)'); var_dump($STH); $result = $STH->execute(array('test', 'nils', '[email protected]', '227a038fe9c81515b514cb152188e95c')); echo "working? <br />"; if($result == false) echo 'noooo...'; It outputs and doesn't put anything in the database. Works with a similare code with DPO just without my DB class. But I doesn't get any errors. Anyone have an idea what the problem could be? object(PDOStatement)#2 (1) { ["queryString"]=> string(87) "INSERT INTO users (username, password, email, activationkey) VALUES (?, UNHEX(?), ?, ?)" } working? <br /> noooo...

  • Where should I define custom routes in my ZF 1.10 app?

    - by Ross
    With the new Zend_Application/Zend_Application_Bootstrap classes I'm confused as to where I should be applying my custom routes. For example, at the moment I have one route: protected function _initRouter() { $router = new Zend_Controller_Router_Rewrite; $route = new Zend_Controller_Router_Route('news/:id', array('controller' => 'news', 'action' => 'view')); $router->addRoute('postArchive', $route); } This method is in my Zend_Application_Bootstrap_Bootstrap and is definitely run. The route is also applied in $router. As I see it I could be doing two things wrong - either the wrong place to add these routes, or not adding to the correct router. Can anyone point me in the right direction with this?

  • SQL Alchemy: Relationship with grandson

    - by giomasce
    I'm building a SQL Alchemy structure with three different levels of objects; for example, consider a simple database to store information about some blogs: there are some Blog object, some Post object and some Comment objects. Each Post belongs to a Blog and each Comment belongs to a Post. Using backref I can automatically have the list of all Posts belonging to a Blog and similarly for Comments. I drafted a skeleton for such a structure. What I would like to do now is to have directly in Blog an array of all the Comments belonging to that Blog. I've tried a few approaches, but they don't work or even make SQL Alchemy cry in ways I can't fix. I'd think that mine is quite a frequent need, but I couldn't find anything helpful. Colud someone suggest me how to do that? Thanks.

  • Check if key exists in $_SESSION by building index string

    - by Kim
    I need to check if a key exists and return its value if it does. Key can be an array with subkeys or endkey with a value. $_SESSION['mainKey']['testkey'] = 'value'; var_dump(doesKeyExist('testkey')); function doesKeyExist($where) { $parts = explode('/',$where); $str = ''; for($i = 0,$len = count($parts);$i<$len;$i++) { $str .= '[\''. $parts[$i] .'\']'; } $keycheck = '$_SESSION[\'mainKey\']' . $str; if (isset(${$keycheck})) { return ${$keycheck}; } // isset($keycheck) = true, as its non-empty. actual content is not checked // isset(${$keycheck}) = false, but should be true. ${$var} forces a evaluate content // isset($_SESSION['mainKey']['testkey']) = true } What am I doing wrong ? Using PHP 5.3.3.

  • what is a fast way to output h5py dataset to text?

    - by user362761
    I am using the h5py python package to read files in HDF5 format. (e.g. somefile.h5) I would like to write the contents of a dataset to a text file. For example, I would like to create a text file with the following contents: 1,20,31,75,142,324,78,12,3,90,8,21,1 I am able to access the dataset in python using this code: import h5py f = h5py.File('/Users/Me/Desktop/thefile.h5', 'r') group = f['/level1/level2/level3'] dset = group['dsetname'] My naive approach is too slow, because my dataset has over 20000 entries: # write all values to file for index in range(len(dset)): # do not add comma after last value if index == len(dset)-1: txtfile.write(repr(dset[index])) else: txtfile.write(repr(dset[index])+',') txtfile.close() return None Is there a faster way to write this to a file? Perhaps I could convert the dataset into a NumPy array or even a Python list, and then use some file-writing tool? (I could experiment with concatenating the values into a larger string before writing to file, but I'm hoping there's something entirely more elegant)

  • How to perform a join with CodeIgniter's Active Record class on a multicolumn key?

    - by Scott Southworth
    I've been able to make this code work using CodeIgniter's db->query as follows: $sql = 'SELECT mapping_code,zone_name,installation_name FROM installations,appearances,zones WHERE installations.installation_id = zones.installation_fk_id AND appearances.installation_fk_id = installations.installation_id AND appearances.zone_fk_id = zones.zone_id AND appearances.barcode = ? '; return $this->db->query($sql,array($barcode)); The 'appearances' table throws a 'not unique table' error if I try this using the Active Record class. I need to join appearances on both the zone and installations tables. How can I do this?

  • How to use pointer from COM object on C#?

    - by Jaeh
    All. I'm trying to use my old dll file on .net project. So I converted this unmanaged COM object to managed one by using [tlbimp.exe] util from Windows SDK. However, one method returns a Object as a return value, but whenever I try to use it, my program generates an error. The weird thing is below: //Object[] item = s.GetObjects(); //this generates an type error Object item = s.GetObjects(); //this works okay System.WriteLine(items); //prints System.Object[] rather than System.Object. It seems like it returns a pointer which contains an object array. Isn't it ? Please anyone tell me how to handle this, and is there any documentation for this issue ?

  • CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

    - by Jason McCreary
    I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

  • PHP readdir() not returning files in alphabetical order

    - by Buggabill
    I am reading through a directory with some pictures and such using a pretty simple implementation of readdir() like the following: if ($handle = opendir($path)) { while (false !== ($szFilename = readdir($handle))) { if ($szFilename[0] !== '.') { if (is_file($path.$szFilename)) { // do stuff } } } } The problem that I am having is that the files are not being read in alphabetical order as the docs for readdir() state: Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem. Another weird thing is that, on the local testing server, the same code works great. This is running on a server using the LAMP stack in both cases. I know that I can build an array and just sort it, but I was wondering if I was missing something in what I was doing. Thanks for any insight!

  • Generic calls to OnResetDevice() and OnLostDevice()

    - by bobobobo
    This is kind of a COM question to do with DirectX. So, both ID3DXSprite and ID3DXFont and a bunch of the other ID3DX* objects require you to call OnLostDevice() when the d3d device is lost AND OnResetDevice() when the device is reset. What I want to do is maintain an array of all ID3DX* objects and simply call OnResetDevice() and OnLostDevice() on each whenever the device is lost or reset. However I can't seem to find a BASE CLASS for the ID3DX* classes... they all seem to COM-ually inherit from IUnknown. Is there a way to do this or do I have to maintain separate arrays of ID3DXFont* pointers, ID3DXSprite* pointers, etc?

  • Python OpenGL Can't Redraw Scene

    - by RobbR
    I'm getting started with OpenGL and shaders using GLUT and PyOpenGL. I can draw a basic scene but for some reason I can't get it to update. E.g. any changes I make during idle(), display(), or reshape() are not reflected. Here are the methods: def display(self): glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT ) glMatrixMode(GL_MODELVIEW) glLoadIdentity() glUseProgram(self.shader_program) self.m_vbo.bind() glEnableClientState( GL_VERTEX_ARRAY ) glVertexPointerf(self.m_vbo) glDrawArrays(GL_TRIANGLES, 0, len(self.m_vbo)) glutSwapBuffers() glutReportErrors() def idle(self): test_change += .1 self.m_vbo = vbo.VBO( array([ [ test_change, 1, 0 ], # triangle [ -1,-1, 0 ], [ 1,-1, 0 ], [ 2,-1, 0 ], # square [ 4,-1, 0 ], [ 4, 1, 0 ], [ 2,-1, 0 ], [ 4, 1, 0 ], [ 2, 1, 0 ], ],'f') ) glutPostRedisplay() def begin(self): glutInit() glutInitWindowSize(400, 400) glutCreateWindow("Simple OpenGL") glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB) glutDisplayFunc(self.display) glutReshapeFunc(self.reshape) glutMouseFunc(self.mouse) glutMotionFunc(self.motion) glutIdleFunc(self.idle) self.define_shaders() glutMainLoop() I'd like to implement a time step in idle() but even basic changes to the vertices or tranlastions and rotations on the MODELVIEW matrix don't display. It just puts up the initial state and does not update. Am I missing something?

  • Obtaining kerning information

    - by chadb
    How can I obtain kerning information for GDI to then use in GetKerningPairs? The documentation states that The number of pairs in the lpkrnpair array. If the font has more than nNumPairs kerning pairs, the function returns an error. However, I do not know how many pairs to pass in, and I don't see a way to query for it. EDIT I tried to do the following, however, it still gave me 0. Font* myFont = new Font(L"Times New Roman", 10); Bitmap* bitmap = new Bitmap(256, 256, PixelFormat32bppARGB); Graphics* g = new Graphics(bitmap); SelectObject(g->GetHDC(), myFont); //DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), -1, NULL ); DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), INT_MAX, NULL );

  • Rapid spectral analysis of audio file using Python 2.6?

    - by Ephemeralis
    What I want to do is to have a subroutine that analyses every 200 milliseconds of a sound file which it is given and spits out the frequency intensity value (from 0 to 1 as a float) of a specific frequency range into an array which I later save. This value then goes on to be used as the opacity value for a graphic which is supposed to 'strobe' to the audio file. The problem is, I have never ventured into audio analysis before and have no clue where to start. I have looked pymedia and scipy/numpy thinking I would be able to use FFT in order to achieve this, but I am not really sure how I would manipulate this data to end up with the desired result. The documentation on the SpectrAnalyzer class of pymedia is virtually non-existant and the examples on the website do not actually work with the latest release of the library - which isn't exactly making my life easier. How would I go about starting this project? I am at a complete loss as to what libraries I should even be using.
