• Dynamic SQL To Dynamic LINQ in VB.NET with MS SQL Server 2008

  - by user337501

  I dread asking this question, because with what I've read so far I understand im gonna have to cram a lotta new things into my head. In spite of all the similiar questions(and the wide variety of answers) I thought I'd ask as nothing I've read tailors to what I need specifically enough. I need to represent the following query using LINQ: DECLARE @PurchasedInventoryItemID Int = 2 DECLARE @PurchasedInventorySectionID Int = 0 DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3 DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0 DECLARE @IsActive Bit = 1 DECLARE @PropertyID Int = 2 DECLARE @PropertyValue nvarchar(1000) = 'Granny Smith' --Property1, Property2, Property3 ... SELECT O.PurchasedInventoryObjectID, O.PurchasedInventoryObjectName, O.PurchasedInventoryConjunctionID, O.Summary, O.Count, O.PropertyCount, O.IsActive FROM tblPurchasedInventoryObject As O INNER JOIN tblPurchasedInventoryConjunction As C ON C.PurchasedInventoryConjunctionID = O.PurchasedInventoryConjunctionID INNER JOIN tblPurchasedInventoryItem As I ON I.PurchasedInventoryItemID = C.PurchasedInventoryItemID INNER JOIN tblPurchasedInventorySection As S ON S.PurchasedInventorySectionID = C.PurchasedInventorySectionID INNER JOIN tblPurchasedInventoryPropertyMap as M ON M.PurchasedInventoryObjectID = O.PurchasedInventoryObjectID INNER JOIN tblPropertyValue As V ON V.PropertyValueID = M.PropertyValueID WHERE I.PurchasedInventoryItemID = @PurchasedInventoryItemID AND S.PurchasedInventorySectionID = @PurchasedInventorySectionID AND I.PurchasingCategoryID = @PurchasedInventoryItem_PurchasingCategoryID AND S.PurchasingCategoryID = @PurchasedInventorySection_PurchasingCategoryID AND O.IsActive = @IsActive AND V.PropertyID = @PropertyID AND V.Value = @PropertyValue Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables. My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times. In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions. I can also make a Stored Procedure in MS SQL, which is easy enough. However, I want to accomplish this using LINQ. If anyone could direct me, I would be most appreciative.

• function's return address is different from its supposed value, buffer overflow,

  - by ultrajohn

  Good day everyone! I’m trying to understand how buffer overflow works. I’m doing this for my project in a computer security course I’m taking. Right now, I’m in the process of determining the address of the function’s return address which I’m supposed to change to perform a buffer overflow attack. I’ve written a simple program based from an example I’ve read in the internet. What this program does is it creates an integer pointer that will be made to point to the address of the function return address in the stack. To do this, (granted I understand how a function/program variables get organized in the stack), I add 8 to the buffer variable’ address and set it as the value of ret. I’m not doing anything here that would change the address contained in the location of func’s return address. here's the program: Output of the program when gets excecuted: As you can see, I’m printing the address of the variables buffer and ret. I’ve added an additional statement printing the value of the ret variable (supposed location of func return address, so this should print the address of the next instruction which will get executed after func returns from execution). Here is the dump which shows the supposed address of the instruction to be executed after func returns. (Underlined in green) As you can see, that value is way different from the value printed contained in the variable ret. My question is, why are they different? (of course in the assumption that what I’ve done are all right). Else, what have I done wrong? Is my understanding of the program’s runtime stack wrong? Please, help me understand this. My project is due nextweek and I’ve barely touched it yet. I’m sorry if I’m being demanding, I badly need your help.

• Templates vs. coded HTML

  - by Alan Harris-Reid

  I have a web-app consisting of some html forms for maintaining some tables (SQlite, with CherryPy for web-server stuff). First I did it entirely 'the Python way', and generated html strings via. code, with common headers, footers, etc. defined as functions in a separate module. I also like the idea of templates, so I tried Jinja2, which I find quite developer-friendly. In the beginning I thought templates were the way to go, but that was when pages were simple. Once .css and .js files were introduced (not necessarily in the same folder as the .html files), and an ever-increasing number of {{...}} variables and {%...%} commands were introduced, things started getting messy at design-time, even though they looked great at run-time. Things got even more difficult when I needed additional javascript in the or sections. As far as I can see, the main advantages of using templates are: Non-dynamic elements of page can easily be viewed in browser during design. Except for {} placeholders, html is kept separate from python code. If your company has a web-page designer, they can still design without knowing Python. while some disadvantages are: {{}} delimiters visible when viewed at design-time in browser Associated .css and .js files have to be in same folder to see effects in browser at design-time. Data, variables, lists, etc., must be prepared in advanced and either declared globally or passed as parameters to render() function. So - when to use 'hard-coded' HTML, and when to use templates? I am not sure of the best way to go, so I would be interested to hear other developers' views. TIA, Alan

• Flash gets XML but the values are wrong, as3

  - by VideoDnd

  Flash receives the XML, but the values are wrong. How do I fix this? Problem I can see the XML loaded with no errors, but my output is way off. It's as though it's not receiving any values. Numbers in the output window and animation move rapidly. The Flash file runs as if it's variables where set to zero. I changed the order of my code, but that didn't help with this. Please explain how I can correct this. SWF //load xml var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("xml.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); //parse XML function processXML(e:Event):void { myXML = new XML(e.target.data); trace(myXML); //receive values from XML delay = parseInt(myXML.DELAY.text()); trace(delay); repeat = parseInt(myXML.REPEAT.text()); trace(repeat); } //variables var delay:uint = 0; var repeat:uint = 0; //timer and event var timer:Timer = new Timer(uint(delay),uint(repeat)); timer.addEventListener(TimerEvent.TIMER, countdown); //counter function countdown(event:TimerEvent) { myText.text = String(0 + timer.currentCount); trace(0 + timer.currentCount); } timer.start(); XML <?xml version="1.0" encoding="utf-8"?> <SESSION> <DELAY TITLE="starting position">1000</DELAY> <REPEAT TITLE="starting position">60</REPEAT> </SESSION>

• Exclude string from wildcard in bash

  - by Peter O'Doherty

  Hi, I'm trying to adapt a bash script from "Sams' Teach Yourself Linux in 24 Hours" which is a safe delete command called rmv. The files are removed by calling rmv -d file1 file2 etc. In the original script a max of 4 files can by removed using the variables $1 $2 $3 $4. I want to extend this to an unlimited number of files by using a wildcard. So I do: for i in $* do mv $i $HOME/.trash done The files are deleted okay but the option -d of the command rmv -d is also treated as an argument and bash objects that it cannot be found. Is there a better way to do this? Thanks, Peter #!/bin/bash # rmv - a safe delete program # uses a trash directory under your home directory mkdir $HOME/.trash 2>/dev/null # four internal script variables are defined cmdlnopts=false delete=false empty=false list=false # uses getopts command to look at command line for any options while getopts "dehl" cmdlnopts; do case "$cmdlnopts" in d ) /bin/echo "deleting: \c" $2 $3 $4 $5 ; delete=true ;; e ) /bin/echo "emptying the trash..." ; empty=true ;; h ) /bin/echo "safe file delete v1.0" /bin/echo "rmv -d[elete] -e[mpty] -h[elp] -l[ist] file1-4" ;; l ) /bin/echo "your .trash directory contains:" ; list=true ;; esac done if [ $delete = true ] then for i in $* do mv $i $HOME/.trash done /bin/echo "rmv finished." fi if [ $empty = true ] then /bin/echo "empty the trash? \c" read answer case "$answer" in y) rm -i $HOME/.trash/* ;; n) /bin/echo "trashcan delete aborted." ;; esac fi if [ $list = true ] then ls -l $HOME/.trash fi

• Why isn't my new object being seen? C#

  - by Dan

  I am getting ready to take a class at a college on C#. I have been reading up on it a lot and decided to start a fun project. Here is what my project consists of: Main Control Form Configuration Form Arduino Program.cs calls Configuration.cs at start. This is where pin modes for the Arduino are set and where a timer is set. When I set these values, they get sent to MainControl.cs. When I hit the "Save" button in Configuration.cs, a MainControl.cs object is created [[I am correct in that?]] All of those values that were sent by Configuration.cs had corresponding setters that set private static variables in MainControl.cs [[ I don't really know if that is the preferred way, I am most definetly open to any suggestion anyone has]] MainControl.cs uses its default constructor, and this constructor calls a method that creates an arduino object from one of the private variables (serialPort) [[ Using this Arduino class Firmata.NET ]] When the arduino object is created, I know (I guess I do) because the form takes a few seconds to come up (As opposed to not using serial port) My problem is this: I do not understand why nothing can see the object I have been very wordy, I apologize if I wasn't concise. Here is the code: public partial class CMainControl : Form { private static string serialPort; public CMainControl() { InitializeComponent(); createArduino(); updateConfig(); // Change label values to values set in configuration } private void createArduino() { Arduino arduino = new Arduino(serialPort); } In Configuration.cs, when I set the serial port through a combobox, the value is sent to MainControl.cs just fine. Here is the error I get: Error 1 The name 'arduino' does not exist in the current context C:\Programming\Visual Studio\Workhead Demo\Workhead Demo\CMainControl.cs 94 13 Workhead Demo Please let me know if anyone can help and/or offer pointers, and please let me know if I didn't post or format anything correctly. Thank you very much :)

• In ParallelPython, a method of an object ( object.func() ) fails to manipulate a variable of an object ( object.value )

  - by mehmet.ali.anil

  With parallelpython, I am trying to convert my old serial code to parallel, which heavily relies on objects that have methods that change that object's variables. A stripped example in which I omit the syntax in favor of simplicity: class Network: self.adjacency_matrix = [ ... ] self.state = [ ... ] self.equilibria = [ ... ] ... def populate_equilibria(self): # this function takes every possible value that self.state can be in # runs the boolean dynamical system # and writes an integer within self.equilibria for each self.state # doesn't return anything I call this method as: Code: j1 = jobserver.submit(net2.populate_equilibria,(),(),("numpy as num")) The job is sumbitted, and I know that a long computation takes place, so I speculate that my code is ran. The problem is, i am new to parallelpython , I was expecting that, when the method is called, the variable net2.equilibria would be written accordingly, and I would get a revised object (net2) . That is how my code works, independent objects with methods that act upon the object's variables. Rather, though the computation is apparent, and reasonably timed, the variable net2.equilibria remains unchanged. As if PP only takes the function and the object, computes it elsewhere, but never returns the object, so I am left with the old one. What do I miss? Thanks in advance.

• Circular Dependency of Navigation Control in iPhone

  - by Taimur Hamza

  Hi everyone , In my view this is one of the strangest problem i have ever come across in iPhone app development. Let me explain the scenario , i have main screen 'A' on which i have a Button that directs me to another Screen say 'B'. Now on Screen 'B' i have a feature in which user can send a mail to his friend for promotion purpose e.g a user wishes to tell a frnd about this app so i used MFMailComposeViewController and a view is generated where the user types the address and click send ( subject and body of mail is automatically generated ). After sending the mail a new view opens say screen 'C' and here i want to give the user the options . 1. Go to Screen 'A' ( which is main screen of the app ) 2. Go back to Screen 'B' ( from where the user requested to send a mail to his frnd ). Now the strange part i cannot declare the variables ( Screen 'A' and 'B' ) of both these files here at in header file of screen 'C' . Even when i declare the header file at the top it generates an error. The variables can be easily be declared and used for other screens but not for these 2 screens. Can anybody please explain wats the problem.? this the text of the error "/Users/admin/Documents/AppName/Classes/A.h:42: error: expected specifier-qualifier-list before 'B'" Thanks Guys ! Taimur

• Python: Networked IDLE/Redo IDLE front-end while using the same back-end?

  - by Rosarch

  Is there any existing web app that lets multiple users work with an interactive IDLE type session at once? Something like: IDLE 2.6.4 Morgan: >>> letters = list("abcdefg") Morgan: >>> # now, how would you iterate over letters? Jack: >>> for char in letters: print "char %s" % char char a char b char c char d char e char f char g Morgan: >>> # nice nice If not, I would like to create one. Is there some module I can use that simulates an interactive session? I'd want an interface like this: def class InteractiveSession(): ''' An interactive Python session ''' def putLine(line): ''' Evaluates line ''' pass def outputLines(): ''' A list of all lines that have been output by the session ''' pass def currentVars(): ''' A dictionary of currently defined variables and their values ''' pass (Although that last function would be more of an extra feature.) To formulate my problem another way: I'd like to create a new front end for IDLE. How can I do this? UPDATE: Or maybe I can simulate IDLE through eval()? UPDATE 2: What if I did something like this: I already have a simple GAE Python chat app set up, that allows users to sign in, make chat rooms, and chat with each other. Instead of just saving incoming messages to the datastore, I could do something like this: def putLine(line, user, chat_room): ''' Evaluates line for the session used by chat_room ''' # get the interactive session for this chat room curr_vars = InteractiveSession.objects.where("chatRoom = %s" % chat_room).get() result = eval(prepared_line, curr_vars.state, {}) curr_vars.state = curr_globals curr_vars.lines.append((user, line)) if result: curr_vars.lines.append(('SELF', result.__str__())) curr_vars.put() The InteractiveSession model: def class InteractiveSession(db.Model): # a dictionary mapping variables to values # it looks like GAE doesn't actually have a dictionary field, so what would be best to use here? state = db.DictionaryProperty() # a transcript of the session # # a list of tuples of the form (user, line_entered) # # looks something like: # # [('Morgan', '# hello'), # ('Jack', 'x = []'), # ('Morgan', 'x.append(1)'), # ('Jack', 'x'), # ('SELF', '[1]')] lines = db.ListProperty() Could this work, or am I way off/this approach is infeasible/I'm duplicating work when I should use something already built?

• Call by Reference Function in C

  - by Chad

  Hello everyone, I would just like a push in the right direction here with my homework assignment. Here is the question: (1) Write a C function called input which returns void, this function prompts the user for input of two integers followed by a double precision value. This function reads these values from the keyboard and finds the product of the two integers entered. The function uses call by reference to communicate the values of the three values read and the product calculated back to the main program. The main program then prints the three values read and the product calculated. Provide test results for the input: 3 5 23.5. Do not use arrays or global variables in your program. And here is my code: #include <stdio.h> #include <stdlib.h> void input(int *day, int *month, double *k, double *pro); int main(void){ int i,j; double k, pro; input(&i, &j, &k, &pro); printf("%f\n", pro); return 0; } void input(int *i, int *j, double *k, double *pro){ int x,y; double z; double product; scanf("%d", &x); scanf("%d", &y); scanf("%f", &z); *pro += (x * y * z); } I can't figure out how to reference the variables with pointers really, it is just not working out for me. Any help would be great!

• dynamically created radiobuttonlist

  - by Janet

  Have a master page. The content page has a list with hyperlinks containing request variables. You click on one of the links to go to the page containing the radiobuttonlist (maybe). First problem: When I get to the new page, I use one of the variables to determine whether to add a radiobuttonlist to a placeholder on the page. I tried to do it in page)_load but then couldn't get the values selected. When I played around doing it in preInit, the first time the page is there, I can't get to the page's controls. (Object reference not set to an instance of an object.) I think it has something to do with the MasterPage and page content? The controls aren't instantiated until later? (using vb by the way) Second problem: Say I get that to work, once I hit a button, can I still access the passed request variable to determine the selected item in the radiobuttonlist? Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit 'get sessions for concurrent Dim Master As New MasterPage Master = Me.Master Dim myContent As ContentPlaceHolder = CType(Page.Master.FindControl("ContentPlaceHolder1"), ContentPlaceHolder) If Request("str") = "1" Then Dim myList As dsSql = New dsSql() ''''instantiate the function to get dataset Dim ds As New Data.DataSet ds = myList.dsConSessionTimes(Request("eid")) If ds.Tables("conSessionTimes").Rows.Count > 0 Then Dim conY As Integer = 1 CType(myContent.FindControl("lblSidCount"), Label).Text = ds.Tables("conSessionTimes").Rows.Count.ToString Sorry to be so needy - but maybe someone could direct me to a page with examples? Maybe seeing it would help it make sense? Thanks....JB

• Can I compare a template variable to an integer in App Engine templates?

  - by matt b

  Using Django templates in Google App Engine (on Python), is it possible to compare a template variable to an integer in an {% if %} block? views.py: class MyHandler(webapp.RequestHandler): def get(self): foo_list = db.GqlQuery(...) ... template_values['foos'] = foo_list template_values['foo_count'] = len(foo_list) handler.response.out.write(template.render(...)) My template: {% if foo_count == 1 %} There is one foo. {% endif %} This blows up with 'if' statement improperly formatted. What I was attempting to do in my template was build a simple if/elif/else tree to be grammatically correct to be able to state #foo_count == 0: There are no foos. #foo_count == 1: There is one foo. #else: There are {{ foos|length }} foos. Browsing the Django template documents (this link provided in the GAE documentation appears to be for versions of Django far newer than what is supported on GAE), it appears as if I can only actually use boolean operators (if in fact boolean operators are supported in this older version of Django) with strings or other template variables. Is it not possible to compare variables to integers or non-strings with Django templates? I'm sure there is an easy way to workaround this - built up the message string on the Python side rather than within the template - but this seems like such a simple operation you ought to be able to handle in a template. It sounds like I should be switching to a more advanced templating engine, but as I am new to Django (templates or any part of it), I'd just like some confirmation first.

• How to connect to bluetoothbee device using j2me?

  I developed a simple bluetooth connection application in j2me. I try it on emulator, both server and client can found each other, but when I deploy the application to blackberry mobile phone and connect to a bluetoothbee device it says service search no records.

• C sharp code cleanup : resharper

  - by Ankit Rathod

  Hello, I just used Resharper in one application and it made me feel as if i don't know how to code at all in C# :(. On every line it gave me it's suggestions :- Few of Resharper's favorite suggestions are :- 1) SomObject o = new SomeObject(); Resharper will convert to : var o = new SomeObject() 2) this.Loaded += new RoutedEventHandler(MainPage_Loaded); to this.Loaded += MainPage_Loaded; 3) convert my variables and putting _ in front of all instance variables. 4) Removing class parent's name. I tested this on Silverlight. public partial class MainPage : UserControl to public partial class MainPage EDIT :- 5) replace instance variable this.variable = somevalue to variable = somevalue Are all of these really necessary? Is it really going to affect the efficiency of my program? I mean what good is it going to do by replacing my class names with var keyword. After all var is also replaced with class name at compile time. Is it doing because it has been programmed to do or do these things really affect in some or another way? Thanks in advance :)

• R: disentangling scopes

  - by rescdsk

  Hi, Right now, in my R project, I have functions1.R with doFoo() and doBar(), functions2.R with other functions, and main.R with the main program in it, which first does source('functions1.R'); source('functions2.R'), and then calls the other functions. I've been starting the program from the R GUI in Mac OS X, with source('main.R'). This is fine the first time, but after that, the variables that were defined the first time through the program are defined for the second time functions*.R are sourced, and so the functions get a whole bunch of extra variables defined. I don't want that! I want an "undefined variable" error when my function uses a variable it shouldn't! Twice this has given me very late nights of debugging! So how do other people deal with this sort of problem? Is there something like source(), but that makes an independent namespace that doesn't fall through to the main one? Making a package seems like one solution, but it seems like a big pain in the butt compared to e.g. Python, where a source file is automatically a separate namespace. Any tips? Thank you!

• Problem executing script using Python and subprocces.call yet works in Bash

  - by Antoine Benkemoun

  Hello, For the first time, I am asking a little bit of help over here as I am more of a ServerFault person. I am doing some scripting in Python and I've been loving the language so far yet I have this little problem which is keeping my script from working. Here is the code line in question : subprocess.call('xen-create-image --hostname '+nom+' --memory '+memory+' --partitions=/root/scripts/part.tmp --ip '+ip+' --netmask '+netmask+' --gateway '+gateway+' --passwd',shell=True) I have tried the same thing with os.popen. All the variables are correctly set. When I execute the command in question in my regular Linux shell, it works perfectly fine but when I execute it using my Python scripts, I get bizarre errors. I even replaced subprocess.call() by the print function to make sure I am using the exact output of the command. I went looking into environment variables of my shell but they are pretty much the same... I'll post the error I am getting but I'm not sure it's relevant to my problem. Use of uninitialized value $lines[0] in substitution (s///) at /usr/share/perl5/Config/IniFiles.pm line 614. Use of uninitialized value $_ in pattern match (m//) at /usr/share/perl5/Config/IniFiles.pm line 628. I am not a Python expert so I'm most likely missing something here. Thank you in advance for your help, Antoine

• calll html button onclick event from asp server side login authenticate event

  - by CraigJSte

  Need to programmatically click an html button from a login event (code behind? the html button sends variables to Flash using method: no response - with no postback and uses ExternalInterface API via javascript. Going from SWF ASPX is great, but need to send User.Identity to SWF from ASPX via javascript after authenticate with login event which am having impossible time getting to work... (calling HTML event from Login button) tried scripting in javascript to login event with no luck, possibly because postback clears SWF variables - so perhaps keeping separate (login then html send) would work... Here is my relevant code: function sendToActionScript(value) { swfobject.getObjectById("Property").sendToActionScript(value); } </script> <object ..// SWF File embedded> </object <form id="form1" runat="server"> <asp:Login id="login1" OnAuthenticate="login1_Authenticate"/> </form> <form id="form" onsubmit="return false;"> <input type="text" name="input" id="input" value="" runat="server" /> <button id="btnInput" runat="server" causesvalidation="false" visible="true" style="width: 51px" onclick="sendToActionScript(this.form.input.value);" >Send</button><br /> </form> // CODE BEHIND protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { // do something to get User Id and Role //bind the string (user or role) to input.value //then call the HTML button onclick event to send it to SWF file. //which I could put in separate function and call from Login_Authenticate } Can anyone help me I am out of ideas.

• Reading a large file into Perl array of arrays and manipulating the output for different purposes

  - by Brian D.

  Hello, I am relatively new to Perl and have only used it for converting small files into different formats and feeding data between programs. Now, I need to step it up a little. I have a file of DNA data that is 5,905 lines long, with 32 fields per line. The fields are not delimited by anything and vary in length within the line, but each field is the same size on all 5905 lines. I need each line fed into a separate array from the file, and each field within the line stored as its own variable. I am having no problems storing one line, but I am having difficulties storing each line successively through the entire file. This is how I separate the first line of the full array into individual variables: my $SampleID = substr("@HorseArray", 0, 7); my $PopulationID = substr("@HorseArray", 9, 4); my $Allele1A = substr("@HorseArray", 14, 3); my $Allele1B = substr("@HorseArray", 17, 3); my $Allele2A = substr("@HorseArray", 21, 3); my $Allele2B = substr("@HorseArray", 24, 3); ...etc. My issues are: 1) I need to store each of the 5905 lines as a separate array. 2) I need to be able to reference each line based on the sample ID, or a group of lines based on population ID and sort them. I can sort and manipulate the data fine once it is defined in variables, I am just having trouble constructing a multidimensional array with each of these fields so I can reference each line at will. Any help or direction is much appreciated. I've poured over the Q&A sections on here, but have not found the answer to my questions yet. Thanks!! -Brian

• Does posting data with a textarea automatically add slashes to (escape) the text?

  - by animuson

  Ok, so I'm having a problem with a simple textarea. I'm using a kind of hidden page to easily encode some data using JSON. However, all of my text input is automatically being escaped somewhere and I don't know where. All of my $_POST variables are automatically run through the htmlentities() function when the script starts up, as seen below: $ani->i->post = $this->clean($_POST, true); function clean($values, $unset = false) { if (is_array($values)) { foreach ($values as $key => $value) { $newkey = strtolower($key); $return[$newkey] = $this->clean($value); unset($values[$key]); } return $return; } return htmlentities($values); } I keep getting \' for all of my single quotes when I put the value back into the textarea. I can't find anywhere where it would be adding slashes and I don't remember it being a feature that they were automatically added when you submit from a textarea, and if that was so, why would they not be returning back to a single quote when put back into the textarea? Do I really need to run variables through stripslashes() to get them back to their original form? Edit: My 'test.php' file is as follows: <h1>To Be Encoded:</h1> <form action="/test" method="post"> <textarea name="encode" rows="20" cols="50"><?= html_entity_decode($ani->i->post['encode']) ?></textarea> <input type="submit" name="submit" value="Encode It!" /> </form> <h1>Encoded By JSON:</h1> <textarea name="encoded" rows="20" cols="50"><?= json_encode(html_entity_decode($ani->i->post['encode'])) ?></textarea> <?php die(); ?> P.S. The die() is just there for compatibility with my framework.

• Optimize CUDA with Thrust in a loop

  - by macs

  Given the following piece of code, generating a kind of code dictionary with CUDA using thrust (C++ template library for CUDA): thrust::device_vector<float> dCodes(codes->begin(), codes->end()); thrust::device_vector<int> dCounts(counts->begin(), counts->end()); thrust::device_vector<int> newCounts(counts->size()); for (int i = 0; i < dCodes.size(); i++) { float code = dCodes[i]; int count = thrust::count(dCodes.begin(), dCodes.end(), code); newCounts[i] = dCounts[i] + count; //Had we already a count in one of the last runs? if (dCounts[i] > 0) { newCounts[i]--; } //Remove thrust::detail::normal_iterator<thrust::device_ptr<float> > newEnd = thrust::remove(dCodes.begin()+i+1, dCodes.end(), code); int dist = thrust::distance(dCodes.begin(), newEnd); dCodes.resize(dist); newCounts.resize(dist); } codes->resize(dCodes.size()); counts->resize(newCounts.size()); thrust::copy(dCodes.begin(), dCodes.end(), codes->begin()); thrust::copy(newCounts.begin(), newCounts.end(), counts->begin()); The problem is, that i've noticed multiple copies of 4 bytes, by using CUDA visual profiler. IMO this is generated by The loop counter i float code, int count and dist Every access to i and the variables noted above This seems to slow down everything (sequential copying of 4 bytes is no fun...). So, how i'm telling thrust, that these variables shall be handled on the device? Or are they already? Using thrust::device_ptr seems not sufficient for me, because i'm not sure whether the for loop around runs on host or on device (which could also be another reason for the slowliness).

• Handling Errors in PHP

  - by Mike

  I have a custom class that, when called, will redirect to a page and send a 'message_type' and 'message' variable via GET. When the page opens it checks for these variables and displays a 'success', 'warning', or 'error' message depending on the 'message_type' variable. I made it so the user thinks they stay on the same page. It also allows for other variables to be passed along with the message. Is this good practice, or should I just start using exceptions? Example: //Call a static function that will redirect to a page, with an error message RedirectWithMessage::go('somepage.php', MessageType::ERROR, 'Error message here.'); The following checkMessage() function is an include file: function checkMessage() { if((isset($_GET['message_type']) && strlen($_GET['message_type'])) && (isset($_GET['message']) && strlen($_GET['message_type']))) { DisplayMessage::display($_GET['message_type'], $_GET['message']); return true; } return false; } On the page that is redirected to, call checkMessage(); //If a message is received, display it. If not, do nothing checkMessage(); I know this might be vague, and I can supply more code if necessary. I guess the issue is that I don't have much experience using exceptions, but I think they seem cumbersome (writing try-catch blocks everywhere). Please let me know if I am making this more difficult for myself or if there is a better solution. Thanks! Mike

• JPanel.addComponentListener does not work when the listener is a class variable

  - by Coder

  I have a public class which has the following method and instance variable: public void setImagePanel(JPanel value) { imagePanel = value; if (imagePanel != null) { //method 1 : works imagePanel.addComponentListener(new ComponentAdapter() { public void componentResized(ComponentEvent evt) { System.out.println("Here 1"); } }); //method 2 : does not work panelResizeListener = new ResizeListener(); imagePanel.addComponentListener(panelResizeListener); //method 3 : works //ResizeListener listener = new ResizeListener(); //imagePanel.addComponentListener(listener); //method 4 : works //imagePanel.addComponentListener(new ResizeListener()); //method 5 : does not work -- THIS IS THE DESIRED CODE I WANT TO USE imagePanel.addComponentListener(panelResizeListener); } } public class ResizeListener extends ComponentAdapter { @Override public void componentResized(ComponentEvent evt) { System.out.println("RESIZE 3"); } } private ResizeListener panelResizeListener = new ResizeListener(); Each of the methods above correspond the to code immediately below until the next //method comment. What i don't understand is why i can't use the class instance variable and add that to the JPanel as a component listener. What happens in the cases above where i say that the method does not work is that i don't get the "RESIZE 3" log messages. In all cases where i list that it works, then i get the "RESIZE 3" messages. The outer class is public with no other modification except that it implements an interface that i created (which has no methods or variables in common with the methods and variables listed above). If anyone can help me i would greatly appreciate it. This problem makes no sense to me, the code should be identical.

• Simple way to repeat a String in java

  - by e5

  I'm looking for a simple commons method or operator that allows me to repeat some String n times. I know I could write this using a for loop, but I wish to avoid for loops whenever necessary and a simple direct method should exist somewhere. String str = "abc"; String repeated = str.repeat(3); repeated.equals("abcabcabc"); Related to: repeat string javascript Create NSString by repeating another string a given number of times Edited I try to avoid for loops when they are not completely necessary because: They add to the number of lines of code even if they are tucked away in another function. Someone reading my code has to figure out what I am doing in that for loop. Even if it is commented and has meaningful variables names, they still have to make sure it is not doing anything "clever". Programmers love to put clever things in for loops, even if I write it to "only do what it is intended to do", that does not preclude someone coming along and adding some additional clever "fix". They are very often easy to get wrong. For loops that involving indexes tend to generate off by one bugs. For loops often reuse the same variables, increasing the chance of really hard to find scoping bugs. For loops increase the number of places a bug hunter has to look.

• ASIHTTPRequest wrapper usage for Macs

  - by Rob

  I am trying to apply the ASIHTTPRequest wrapper to a very basic Objective C program. I have already copied over the necessary files into my program and after giving myself an extreme headache trying to figure out how it works through their website I thought I would post a question on here. The files copied over were: ASIHTTPRequestConfig.h ASIHTTPRequestDelegate.h ASIProgressDelegate.h ASIInputStream.h ASIInputStream.m ASIHTTPRequest.h ASIHTTPRequest.m ASIFormDataRequest.h ASIFormDataRequest.m My program is very basic: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; // Defining the various variables. char firstName[20]; char lastName[20]; char rank[5]; int leaveAccrued; int leaveRequested; // User Input. NSLog (@"Please input First Name:"); scanf("%s", &firstName); NSLog (@"Please input Last Name:"); scanf("%s", &lastName); NSLog (@"Please input Rank:"); scanf("%s", &rank); NSLog (@"Please input the number leave days you have accrued:"); scanf("%i", &leaveAccrued); NSLog (@"Please input the number of leave days you are requesting:"); scanf("%i", &leaveRequested); // Print results. NSLog (@"Name: %s %s", firstName, lastName); NSLog (@"Rank: %s", rank); NSLog (@"Leave Accrued: %i", leaveAccrued); NSLog (@"Leave Requested: %i", leaveRequested); [pool drain]; return 0; } How do I utilize the wrapper to export these 5 basic variables to a web server via an http request?
