  • Problem resizing image using Code Ignitor1.7.3

    - by Yashwant Chavan
    Following is the code which resize the image, but here i am not able to resize the image function processHome(){ $this->load->library('image_lib'); $img_path = base_url().'img/image/50X50/ori.jpeg'; $config['image_library'] = 'gd2'; $config['source_image'] = $img_path; $config['create_thumb'] = TRUE; $config['maintain_ratio'] = TRUE; $config['width'] = 50; $config['height'] = 50; $this->load->library('image_lib', $config); $this->image_lib->resize(); if ( ! $this->image_lib->resize()){ echo $this->image_lib->display_errors(); } echo "No error"; exit; $this->load->view('index', $data); }

  • Transportation Web App - utilizing google or bing map api

    - by BillS
    I am working on a transportation web app and I am having a bit of a problem. First, I want to be able to define a shipping corridor, say like I-95 between Baltimore MD and Richmond VA. And store what parameters I need to define this route. Users will then use a web interface and can select various routes, in this case, I-95. Vendors will be posting constantly changing pickup locations in the application database which have a shelf life of about 2 days. Some of these locations maybe along this route. I am storing the LAT and LONG for the specific location right now. If any of these points ARE along or within 2 mile of the route (just off the highway basically - the ideal check would based on an actual highway exit but at this point anything would work), I want them to show up in my search results. Any ideas or suggestions?

  • Need help regarding Async and fsi

    - by Stringer Bell
    I'd like to write some code that runs a sequence of F# scripts (.fsx). The thing is that I could have literally hundreds of scripts and if I do that: let shellExecute program args = let startInfo = new ProcessStartInfo() do startInfo.FileName <- program do startInfo.Arguments <- args do startInfo.UseShellExecute <- true do startInfo.WindowStyle <- ProcessWindowStyle.Hidden //do printfn "%s" startInfo.Arguments let proc = Process.Start(startInfo) () scripts |> Seq.iter (shellExecute "fsi") it could stress too much my 2GB system. Anyway, I'd like to run scripts by batch of n, which seems also a good exercise for learning Async (I guess it's the way to go). I have written some code and unfortunately it doesn't work: open System.Diagnostics let p = shellExecute "fsi" @"C:\Users\Stringer\foo.fsx" async { let! exit = Async.AwaitEvent p.Exited do printfn "process has exited" } |> Async.StartImmediate foo.fsx is just a hello world script. I'd like also to figure out if it's doable to retrieve a return code for each executing script and if not, find another way. Thanks!

  • msvsmon is locking up my pdbs

    - by Sam Saffron
    During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

  • Python ValueError: not allowed to raise maximum limit

    - by Ricky Bobby
    I'm using python 2.7.2 on mac os 10.7.3 I'm doing a recursive algorithm in python with more than 50 000 recursion levels. I tried to increase the maximum recursion level to 1 000 000 but my python shell still exit after 18 000 recursion levels. I tried to increase the resources available : import resource resource.setrlimit(resource.RLIMIT_STACK, (2**29,-1)) sys.setrecursionlimit(10**6) and I get this error : Traceback (most recent call last): File "<pyshell#58>", line 1, in <module> resource.setrlimit(resource.RLIMIT_STACK,(2**29,-1)) ValueError: not allowed to raise maximum limit I don't know why I cannot raise the maximum limit ? thanks for your suggestions .

  • Convert Decimal to ASCII

    - by Dan Snyder
    I'm having difficulty using reinterpret_cast. Before I show you my code I'll let you know what I'm trying to do. I'm trying to get a filename from a vector full of data being used by a MIPS I processor I designed. Basically what I do is compile a binary from a test program for my processor, dump all the hex's from the binary into a vector in my c++ program, convert all of those hex's to decimal integers and store them in a DataMemory vector which is the data memory unit for my processor. I also have instruction memory. So When my processor runs a SYSCALL instruction such as "Open File" my C++ operating system emulator receives a pointer to the beginning of the filename in my data memory. So keep in mind that data memory is full of ints, strings, globals, locals, all sorts of stuff. When I'm told where the filename starts I do the following: Convert the whole decimal integer element that is being pointed to to its ASCII character representation, and then search from left to right to see if the string terminates, if not then just load each character consecutively into a "filename" string. Do this until termination of the string in memory and then store filename in a table. My difficulty is generating filename from my memory. Here is an example of what I'm trying to do: C++ Syntax (Toggle Plain Text) 1.Index Vector NewVector ASCII filename 2.0 240faef0 128123792 'abc7' 'a' 3.0 240faef0 128123792 'abc7' 'ab' 4.0 240faef0 128123792 'abc7' 'abc' 5.0 240faef0 128123792 'abc7' 'abc7' 6.1 1234567a 243225 'k2s0' 'abc7k' 7.1 1234567a 243225 'k2s0' 'abc7k2' 8.1 1234567a 243225 'k2s0' 'abc7k2s' 9. //EXIT LOOP// 10.1 1234567a 243225 'k2s0' 'abc7k2s' Index Vector NewVector ASCII filename 0 240faef0 128123792 'abc7' 'a' 0 240faef0 128123792 'abc7' 'ab' 0 240faef0 128123792 'abc7' 'abc' 0 240faef0 128123792 'abc7' 'abc7' 1 1234567a 243225 'k2s0' 'abc7k' 1 1234567a 243225 'k2s0' 'abc7k2' 1 1234567a 243225 'k2s0' 'abc7k2s' //EXIT LOOP// 1 1234567a 243225 'k2s0' 'abc7k2s' Here is the code that I've written so far to get filename (I'm just applying this to element 1000 of my DataMemory vector to test functionality. 1000 is arbitrary.): C++ Syntax (Toggle Plain Text) 1.int i = 0; 2.int step = 1000;//top->a0; 3.string filename; 4.char *temp = reinterpret_cast<char*>( DataMemory[1000] );//convert to char 5.cout << "a0:" << top->a0 << endl;//pointer supplied 6.cout << "Data:" << DataMemory[top->a0] << endl;//my vector at pointed to location 7.cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing 8.cout << "Characters:" << &temp << endl;//my temporary char array 9. 10.while(&temp[i]!=0) 11.{ 12. filename+=temp[i];//add most recent non-terminated character to string 13. i++; 14. if(i==4)//when 4 chatacters have been added.. 15. { 16. i=0; 17. step+=1;//restart loop at the next element in DataMemory 18. temp = reinterpret_cast<char*>( DataMemory[step] ); 19. } 20. } 21. cout << "Filename:" << filename << endl; int i = 0; int step = 1000;//top-a0; string filename; char *temp = reinterpret_cast( DataMemory[1000] );//convert to char cout << "a0:" << top-a0 << endl;//pointer supplied cout << "Data:" << DataMemory[top-a0] << endl;//my vector at pointed to location cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing cout << "Characters:" << &temp << endl;//my temporary char array while(&temp[i]!=0) { filename+=temp[i];//add most recent non-terminated character to string i++; if(i==3)//when 4 chatacters have been added.. { i=0; step+=1;//restart loop at the next element in DataMemory temp = reinterpret_cast( DataMemory[step] ); } } cout << "Filename:" << filename << endl; So the issue is that when I do the conversion of my decimal element to a char array I assume that 8 hex #'s will give me 4 characters. Why isn't this this case? Here is my output: C++ Syntax (Toggle Plain Text) 1.a0:0 2.Data:0 3.Data(1000):4428576 4.Characters:0x7fff5fbff128 5.Segmentation fault

  • Is there a way to move two squares in OpenGL simultaneously?

    - by thyrgle
    Hi, so I have a function that handles key presses in a game I'm working on in OpenGL. But, the thing is that even though I have made two squares and they both move when the correct key is pressed only one square is moved. Is there a way I can make the two squares move. This is the glutKeyboardFunc function I implimented: void handleKeypress(unsigned char key, int x, int y) { switch (key) { case 27: exit(0); break; case 'w': glutTimerFunc(0.001, moveSquareUp, 0); break; case 'd': glutTimerFunc(0.001, moveSquareRight, 0); break; case 's': glutTimerFunc(0.001, moveSquareDown, 0); break; case 'a': glutTimerFunc(0.001, moveSquareLeft, 0); break; } } If you need any more code just ask.

  • Instant Messenger: How does gtalk/yahoo messenger populate the contact list?

    - by Owen
    Hi All, We are currently working on a small IM project which pretty much works like gtalk and yahoo messenger. We came across a problem that puzzled us how gtalk/ym populate their contact lists. Given that the user has let's say more or less 500 contacts, both IMs seem to readily load the contacts pretty fast and already sorted. Here are my questions(referring to either): Does it cache its contacts, like saving it in a file somewhere upon exit so that upon log-in it readily extracts the contacts and displays it in its contact list? Does it always request for the VCARDS upon log in? OR they have a VCARD push or whatever that simply updates the contacts' profiles (like that of their status [presence push - available, busy, etc...] )?

  • Win32 select/poll/eof/ANYTHING!?!?!

    - by Andrew
    Using the standard Win32 file I/O API's (CreateFile/ReadFile/etc), I'm trying to wait for a file to become readable, or for an exception to occur on the file. If Windows had any decent POSIX support, I could just do: select(file_count, files_waiting_for_read, NULL, files_waiting_for_excpt, NULL, NULL); And select will return when there's anything interesting on some of the files. Windows doesn't support select or poll. Fine. I figured I could take the file and do something like: while(eof(file_descriptor)) { Sleep(100); } The above loop would exit when more data is available to be read. But nope, Windows doesn't have an equivalent of eof() either! I could possibly call ReadFile() on the file, and determine if it's at the eof that way. But, then I'd have to handle the reading at that point in time -- I'm hoping to simply be able to figure out that a file is readable, without actually reading it. What are my options?

  • Does this feature exist? Defining my own curly brackets in C#

    - by Carlos
    You'll appreciate the following two syntactic sugars: lock(obj) { //Code } same as: Monitor.Enter(obj) try { //Code } finally { Monitor.Exit(obj) } and using(var adapt = new adapter()){ //Code2 } same as: var adapt= new adapter() try{ //Code2 } finally{ adapt.Dispose() } Clearly the first example in each case is more readable. Is there a way to define this kind of thing myself, either in the C# language, or in the IDE? The reason I ask is that there are many similar usages (of the long kind) that would benefit from this, eg. if you're using ReaderWriterLockSlim, you want something pretty similar.

  • Detecting if Excel file has been closed

    - by Charlie
    Hi StackOverflow, I've spent the past 3 hours trawling the web for answers to no avail, so I hope you can help me. I'm writing an application which automates Excel. The application has an option to "show/hide the excel sheet" so you can look at it, make any final changes and so forth. Closing the application will naturally close the instance of Excel, however, there is a small chance that someone may exit out of Excel directly, without thinking. This breaks my application and I can't seem to find anyway of "checking if the same workbook is still open, and if not, re-opening it", before saving it I've tried all sorts of things: checking if the Excel Application is null (when it's !=null it will save correctly, but when it "is" null (or at least, something other than !=null it won't even hit the breakpoint so I'm completely lost :( Help please?

  • CakePHP and jQuery - Unobtrusive actions

    I'm trying to make an unobtrusive action for deleting bookmarks in CakePHP. Allthough it's working just fine, I suspect there must be a better way to do this. Could someone please point me in the right direction? function delete($id = null) { $ok = $this->Bookmark->delete($id); if($this->RequestHandler->isAjax()) { $this->autoRender = false; $this->autoLayout = false; $response = array('status' => 0, 'message' => 'Could not delete bookmark'); if($ok) { $response = array('status' => 1, 'message' => 'Bookmark deleted'); } $this->header('Content-Type: application/json'); echo json_encode($response); exit(); } // Request isn't AJAX, redirect. $this->redirect(array('action' => 'index')); }

  • Python subprocess.Popen

    - by Albert
    I have that code: #!/usr/bin/python -u localport = 9876 import sys, re, os from subprocess import * tun = Popen(["./newtunnel", "22", str(localport)], stdout=PIPE, stderr=STDOUT) print "** Started tunnel, waiting to be ready ..." for l in tun.stdout: sys.stdout.write(l) if re.search("Waiting for connection", l): print "** Ready for SSH !" break The "./newtunnel" will not exit, it will constantly output more and more data to stdout. However, that code will not give any output and just keeps waiting in the tun.stdout. When I kill the newtunnel process externally, it flushes all the data to tun.stdout. So it seems that I can't get any data from the tun.stdout while it is still running. Why is that? How can I get the information? Note that the default bufsize for Popen is 0 (unbuffered). I can also specify bufsize=0 but that doesn't change anything.

  • Using 'git pull' vs 'git checkout -f' for website deployment

    - by Michelle
    I've found two common approaches to automatically deploying website updates using a bare remote repo. The first requires that the repo is cloned into the document root of the webserver and in the post-update hook a git pull is used. cd /srv/www/siteA/ || exit unset GIT_DIR git pull hub master The second approach adds a 'detached work tree' to the bare repository. The post-receive hook uses git checkout -f to replicate the repository's HEAD into the work directory which is the webservers document root i.e. GIT_WORK_TREE=/srv/www/siteA/ git checkout -f The first approach has the advantage that changes made in the websites working directory can be committed and pushed back to the bare repo (however files should not be updated on the live server). The second approach has the advantage that the git directory is not within the document root but this is easily solved using htaccess. Is one method objectively better than the other in terms of best practice? What other advantages and disadvantages am I missing?

  • Is it safe to catch an access violation in this scenario?

    - by Eloff
    I've read a lot, including here on SO that suggests this is a very bad idea in general and that the only thing you can do safely is exit the program. I'm not sure that this is true. This is for a pooling memory allocator that hands off large allocations to malloc. During pool_free() a pointer needs to be checked it it belongs to a pool or was allocated with malloc. By rounding the address down to the nearest 1MB boundary, I get a pointer to the beginning of a block of memory in the pool, or undefined if malloc was used. In the first case I can easily verify that the block of memory belongs to the pool, but, if it does not I will either fail this verification, or I will get an access violation (note that this is a read-only process). Could I not catch this with SEH (Windows) or handle the signal (POSIX) and simply treat it as a failed verification? (i.e. this is only possible if malloc was used, so pass the ptr to free())

    I was wondering if it was possible to read a text file that was located in a directory called "/home/user/files" I wanted to read it from my cgi-bin which is located in /home/user/cgi-bi/ Below is my code, #!/usr/bin/perl use strict; use CGI; #Virtual Directory #Steffan Harris eval { use constant PASSWORD => 'perl'; use constant UPLOAD_DIR => '/home/sharris2/files'; sub mapToFile { print chdir UPLOAD_DIR; } #This function will list all files in a directory. sub listDirectoryFiles { chdir UPLOAD_DIR; my @files = <*>; mapToFile; print<<LIST; <h2>Current Files</h2> <ul> LIST if(!$files[0]) { print" </ul>\n<em>No files in directory</em>"; } foreach(@files) { print" <li>$_</li>"; } print " </ul>\n"; } #This function generates a 404 Not Found error sub generate404 { print<<RESPONSE; Status: 404 Not Found Content-Type: text/html <html> <head><title>404 Not Found</title></head> <body> <p> <h1>404 - Not Found</h1> </p> The requested URL <b>$ENV{"HTTP_HOST"}$ENV{"REQUEST_URI"}</b> was not found on the server. </body> </html> RESPONSE exit; } #This function checks the path info to see if it matches a file in the UPLOAD_DIR directory, If it does not, then it returns a 404 error sub checkExsistence { if($ENV{"PATH_INFO"}) { chdir UPLOAD_DIR; my @files = <*>; if(!$files[0] and $ENV{"PATH_INFO"} eq "/") { return; } foreach(@files) { if($ENV{"PATH_INFO"} eq "/".$_ || $ENV{"PATH_INFO"} eq "/") { print "yes"; return; } } generate404; } } sub checkPassword { my ($password, $cgi); $cgi = new CGI; $password = $cgi->param('passwd'); unless($password eq PASSWORD) { print<<RESPONSE; Status: 200 OK Content-Type: text/html <html> <head> <title>Incorrect Password</title> </head> <body> <h1>Invalid password entered.</h1> <h3><a href="/~sharris2/cgi-bin/files/">Go Back</a></h3> </body> RESPONSE exit; } } sub upLoadFile { checkPassword; my ($uploadfile, $cgi); $cgi = new CGI; $uploadfile = $cgi->upload('uploadfile'); chdir UPLOAD_DIR; $uploadfile or die "Did not receive a file to upload"; open my $FILE, '>', UPLOAD_DIR."/$uploadfile" or die "$!"; while(<$uploadfile>) { print $FILE $_; } } #Start of main part of program my $cgi = new CGI; if(!$ENV{"PATH_INFO"}) { print $cgi->redirect('/~sharris2/cgi-bin/files/'); } checkExsistence; if($ENV{"REQUEST_METHOD"} eq "POST") { upLoadFile; } print <<"HEADERS"; Status: 200 OK Content-Type: text/html HEADERS print <<"HTML"; <html> <head> <title>Virtual Directory</title> </head> <body> HTML listDirectoryFiles; print<<HTML; <h2>Upload a new file</h2> <form method = "POST" enctype = "multipart/form-data" action = "/~sharris2/cgi-bin/files/" /> File:<input type = "file" name="uploadfile"/> <p>Password: <input type = "password" name ="passwd"/></p> <p><input type = "submit" value= "Submit File" /></p> </form> </body> </html> HTML };

  • I am trying to move a rectangle in Pygame using coordinates but won't work

    - by user1821449
    this is my code import pygame from pygame.locals import * import sys pygame.init() pygame.display.set_caption("*no current mission*") size = (1280, 750) screen = pygame.display.set_mode(size) clock = pygame.time.Clock() bg = pygame.image.load("bg1.png") guy = pygame.image.load("hero_stand.png") rect = guy.get_rect() x = 10 y = 10 while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() if event.type == KEYDOWN: _if event.key == K_RIGHT: x += 5 rect.move(x,y)_ rect.move(x,y) screen.blit(bg,(0,0)) screen.blit(guy, rect) pygame.display.flip() it is just a simple test to see if i can get a rectangle to move. Everything seems to work except the code I put in italic.

  • ArrayList access

    - by Ricky McQuesten
    So once again I have a question about this program. I want to store transactions that are made in an arraylist and then have an option in the case menu where I can print out those that are stored. I have been researching online and have been unable to find a solution to this, so is this possible and how would I go about doing this? I also want to attach a timestamp to each transaction as well. Here is the code I have so far. So my question is how would I add a timestamp to each withdrawal or deposit, and how would I store each transaction in array list? import java.util.*; public class BankAccount extends Money { //inheritence static String name; public static int acctNum; public static double balance, amount; BankAccount(String name, int accNo, double bal) { this.name = name; this.acctNum = accNo; this.balance = bal; } void display() { System.out.println("Your Name:" + name); System.out.println("Your Account Number:" + acctNum); System.out.println("Your Current Account Balance:" + Money.getBalance()); } void displayBalance() { System.out.println("Balance:" + balance); } } import java.util.Scanner; /** * * @author Ricky */ public class Money { public static int accountNumber; public static double balance; static double amount; static String name; public void setDeposit(double amount) { balance = balance + amount; if (amount < 0) { System.out.println("Invalid"); } } public double getDeposit() { return 1; } public void setBalance(double b) { balance = b; } public static double getBalance() { return balance; } public void setWithdraw(double amount) { if (balance < amount) { System.out.println("Not enough funds."); } else if(amount < 0) { System.out.println("Invalid"); } else { balance = balance - amount; } } public double getWithdraw() { return 1; } } import java.util.*; public class Client { public static void main(String args[]) { int n = 0; int count; String trans; ArrayList<String> transaction= new ArrayList<String>(n); Scanner input = new Scanner(System.in); System.out.println("Welcome to First National Bank"); System.out.println("Please enter your name: "); String cusName = input.nextLine(); System.out.println("You will now be assigned an account number."); Random randomGenerator = new Random(); int accNo = randomGenerator.nextInt(100000); //random number System.out.println("Your account number is: " + accNo); System.out.println("Please enter your initial account balance: "); Double balance = input.nextDouble(); BankAccount b1 = new BankAccount(cusName, accNo, balance); b1.setBalance(balance); int menu; /*System.out.println("Menu"); System.out.println("1. Deposit Amount"); System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit");*/ boolean quit = false; do { System.out.println("*******Menu*******"); System.out.println("1. Deposit Amount"); // menu to take input from user System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit"); System.out.print("Please enter your choice: "); menu = input.nextInt(); switch (menu) { case 1: System.out.print("Enter depost amount:"); b1.setDeposit(input.nextDouble()); b1.getDeposit(); transaction.add(trans); break; case 2: System.out.println("Current Account Balance=" + b1.getBalance()); System.out.print("Enter withdrawal amount:"); b1.setWithdraw(input.nextDouble()); b1.getWithdraw(); transaction.add(trans); break; // switch statments to do a loop case 3: b1.display(); break; case 4: quit = true; break; } } while (!quit); } } public class Date { static Date time = new Date(); }
