• Invoking a function call in a string in an Oracle Procedure

  - by DMS

  Hello, I writing an application using Oracle 10g. I am currently facing this problem. I take in "filename" as parameter of type varchar2. A sample value that filename may contain is: 'TEST || to_char(sysdate, 'DDD')'. In the procedure, I want to get the value of this file name as in TEST147. When i write: select filename into ffilename from dual; I get the value ffilename = TEST || to_char(sysdate, 'DDD') whick makes sense. But how can I get around this issue and invoke the function in the string value? Help appreciated. Thanks.

• Can NSUserDefaults be used for pausing the application during a phone call ?

  - by Anil Kumar

  Friends, currently I dont have iphone to test and using Simulator for testing purposes. I am Just curious to know whether an application continues to run even after a phone call.. here i have no option to test this from simulator. If it terminates then how can i pause things.. and continue after a phone call. Is NSUserDefaults can be used for my case. As far I understood NSuserDefaults are used to store data that is required when the App is next time loaded. But here I dont want my App to terminate instead pause until Call ends and continue as uninterrupted later. Please clear me about this. Sorry I am still a beginner so I request for no harsh replies if my question looks stupid. Thanks in Advance

• n00b: receive input over TCP/IP and use it to update HTML

  - by mawg

  This has got to be a FAQ, so can someone please just direct me to a "network programming for dummies" URL? The server wants to push information to a client or broadcast to all, when an event happens - as opposed to the clients constantly polling the server "just in case". The client then updates a browser page display. How do I do that? (toldya it was a n00b question) Should I have a thread which receives info on a socket and then writes it to a database which the browser display (PHP) can process with an HTML refresh tag, or what? Sorry to sound so dumb.

• Segmentation fault when using files C++

  - by Popa Mihai

  I am using ubuntu 12.04. I have been trying a few IDE's for simple C++ school projects. However, with codelite, anjuta and kdevelop I encountered a problem: when I am trying to read / write in files I get segmentation fault: core dumped. I am using a basic source: #include<stdio.h> FILE*f=fopen("test.in","r"); FILE*g=fopen("test.out","w"); int main () { int a,b; fscanf(f,"%d %d",&a,&b); fprintf(g,"%d\n",a+b); fclose(f); fclose(g); return 0; } I have to say that programs with stdin/stdout work well. Thank you,

• Django remove list_editable on a per row basis.

  - by Jason Leveille

  On the back of Django 1.2RC1, I have built a great administrator for my client! It's awesome. The client has one request that, if not satisfied, could bring this house of cards crashing down. I have a list of swim meet results. A meet result is added by a superuser. A team rep can edit a meet result (which they must be able to do inline, with list_editable), but after they edit the meet result inline and save, they should no longer be able to edit that result inline. They can only perform one edit. So, my question ... can I turn off list_editable on a per row basis?

• Reading membership section from web.config in C#

  - by PlayKid

  Hi there, I have created a custom MembershipProvider class, so far so good, however, I am not sure how to read the configuration settings from the web.config file. I tried to search from Google and Stackoverflow, seems like someone also experiencing my problem and asked, but no answer has been given. It should be a simple thing, but I am very new in web development, so reading settings from web.config seems away too technical to me. Here is my settings: <membership defaultProvider="CustomMembershipProvider"> <providers> <clear/> <add name="CustomMembershipProvider" type="Test.Models.CustomMembershipProvider,Test" passwordFormat="Hashed" connectionStringName="ApplicationServices" minRequiredPasswordLength="8" minRequiredNonalphanumericCharacters="0" maxInvalidPasswordAttempts="5" enablePasswordReset="false" enablePasswordRetrieval="false" requiresQuestionAndAnswer="false" applicationName="/"/> </providers> </membership I would like to read the minRequiredPasswordLength setting, please assist. Thanks alot in advance.

• Argument constraints in RhinoMock methods

  - by Khash

  I am mocking a repository that should have 1 entity in it for the test scenario. The repository has to return this entity based on a known id and return nothing when other ids are passed in. I have tried doing something like this: _myRepository.Expect(item => item.Find(knownId)).Return(knownEntity); _myRepository.Expect(item => item.Find(Arg<Guid>.Is.Anything)).Return(null); It seems however the second line is overriding the first and the repository always returns null. I don't want to mock all the different possible IDs asked (they could go up to hundreds) when the test scenario is only concerned with the value of one Id.

• Advice for building a browser-based audio mixer up to 32 tracks

  - by Jonathan P.

  As a personal hobby I am looking to build an online audio mixer where I can upload individual instrument tracks, control individual volumes of each track, and export the mixed down version. I've been trying (and have come pretty close) with javascript. I really would like to stay away from flash if possible, but I'm really looking for suggestions for technologies to try. If anyone has any suggestions on languages that are good at stuff like this or libraries that I am missing, please let me know! I have a test environment that I have been using: http://driverstestpractice.com/sandbox Currently all tracks on the site are set to the click track in order to test the track sync (which as you can tell is a little off)! Thanks!

• sIFR seems to be loading correctly but not displaying text.

  - by CMal

  I'm Using sIFR 3r436, and although I believe everything is set up correctly, and my console shows that the .swf font file is loading correctly, the HTML type is hidden but the sIFR type is not displaying. Below is a link to the site in question: Schaffer's Website Below is a link to a test site that uses exactly the same sifr-config.js, sifr.js, css, and swf files. And it works. The main difference between the two is the server that they are running on. Schaffer's Test Site I'm hoping that maybe somebody can see a problem that I'm unable to. Appreciate the help!

• 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.

• IO.Directory.Exists always returns true

  - by roygbiv

  I am executing a IO.Directory.Exists on a network share from an ASP.NET application running under a specific Application Pool with a specific user account. The call always returns true. I have tried several variations: \\server\share$\directory \\192.168.0.1\share$\directory H:\directory I have checked that directory and share permissions are available to the account. The path does have spaces in it \\server\share$\directory\name name\test test, which should make no difference, however I have read otherwise. I will continue to check permissions, as it does work from my local machine (with the built in VS web-server and I am an administrator on the network), but when deployed to the IIS 6.0 virtual directory, and run under the Application Pool, it does not work.

• Sending files through a webservice

  - by Jay

  Hi, I have to send some files through a webservice in C#. The files to be sent can be from different locations i.e. there is one folder having 4 files and another folder having 5 files. Assuming i have a mechanism to select which files to send. What would be the best way to send those files? Should I be sending them one by one and let the client figure out how to put them together, or zip all the files into a single file and send that zip file to the client. If there is any other way to implement this, I would be more than happy to look into that approach too. Thanks

• Testing methods called on yielded object

  - by Todd R

  I have the following controller test case: def test_showplain Cleaner.expect(:parse).with(@somecontent) Cleaner.any_instance.stubs(:plainversion).returns(@returnvalue) post :showplain, {:content => @somecontent} end This works fine, except that I want the "stubs(:plainversion)" to be an "expects(:plainversion)". Here's the controller code: def showplain Cleaner.parse(params[:content]) do | cleaner | @output = cleaner.plainversion end end And the Cleaner is simply: class Cleaner ### other code and methods ### def self.parse(@content) cleaner = Cleaner.new(@content) yield cleaner cleaner.close end def plainversion ### operate on @content and return ### end end Again, I can't figure out how to reliably test the "cleaner" that is made available from the "parse" method. Any suggestions?

• Creating TCP network errors for unit testing

  - by Robert S. Barnes

  I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

• What do I need to distribute (keys, certs) for Python w/ SSL-socket connection?

  - by fandingo

  I'm trying to write a generic server-client application that will be able to exchange data amongst servers. I've read over quite a few OpenSSL documents, and I have successfully setup my own CA and created a cert (and private key) for testing purposes. I'm stuck with Python 2.3, so I can't use the standard "ssl" library. Instead, I'm stuck with PyOpenSSL, which doesn't seem bad, but there aren't many documents out there about it. My question isn't really about getting it working. I'm more confused about the certificates and where they need to go. Here are my two programs that do work: Server: #!/bin/env python from OpenSSL import SSL import socket import pickle def verify_cb(conn, cert, errnum, depth, ok): print('Got cert: %s' % cert.get_subject()) return ok ctx = SSL.Context(SSL.TLSv1_METHOD) ctx.set_verify(SSL.VERIFY_PEER|SSL.VERIFY_FAIL_IF_NO_PEER_CERT, verify_cb) # ?????? ctx.use_privatekey_file('./Dmgr-key.pem') ctx.use_certificate_file('Dmgr-cert.pem') # ?????? ctx.load_verify_locations('./CAcert.pem') server = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) server.bind(('', 50000)) server.listen(3) a, b = server.accept() c = a.recv(1024) print(c) Client: from OpenSSL import SSL import socket import pickle def verify_cb(conn, cert, errnum, depth, ok): print('Got cert: %s' % cert.get_subject()) return ok ctx = SSL.Context(SSL.TLSv1_METHOD) ctx.set_verify(SSL.VERIFY_PEER, verify_cb) # ?????????? ctx.use_privatekey_file('/home/justin/code/work/CA/private/Dmgr-key.pem') ctx.use_certificate_file('/home/justin/code/work/CA/Dmgr-cert.pem') # ????????? ctx.load_verify_locations('/home/justin/code/work/CA/CAcert.pem') sock = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) sock.connect(('10.0.0.3', 50000)) a = Tester(2, 2) b = pickle.dumps(a) sock.send("Hello, world") sock.flush() sock.send(b) sock.shutdown() sock.close() I found this information from ftp://ftp.pbone.net/mirror/ftp.pld-linux.org/dists/2.0/PLD/i586/PLD/RPMS/python-pyOpenSSL-examples-0.6-2.i586.rpm which contains some example scripts. As you might gather, I don't fully understand the sections between the " # ????????." I don't get why the certificate and private key are needed on both the client and server. I'm not sure where each should go, but shouldn't I only need to distribute one part of the key (probably the public part)? It undermines the purpose of having asymmetric keys if you still need both on each server, right? I tried alternating removing either the pkey or cert on either box, and I get the following error no matter which I remove: OpenSSL.SSL.Error: [('SSL routines', 'SSL3_READ_BYTES', 'sslv3 alert handshake failure'), ('SSL routines', 'SSL3_WRITE_BYTES', 'ssl handshake failure')] Could someone explain if this is the expected behavior for SSL. Do I really need to distribute the private key and public cert to all my clients? I'm trying to avoid any huge security problems, and leaking private keys would tend to be a big one... Thanks for the help!

• Blackberry 507 Erorr

  - by Haoest

  I didn't think it would be so catastrophic when I typed JavaLoader -usb wipe -a into the command line with my blackberry 8800 test device. It reboots with a 507 error that I can't get rid of. I have Blackberry Desktop Manager 4.6, which is normally what I use to upload my test apps, but this time I go to Application Loader, hitting start gives me that dialog box that shows me the list of 1 USB connection "PIN: xxx" with a password field (which I have no idea of,) then it says "connecting to boot ROM" then stops at the message: A connection to the device can not be established... Now is there a hard physical way of resetting my blackberry 8800, please?

• Django refresh page if change data by other user

  - by Fran Sobrino

  I have a test django app. In one page the test show the same question to all users. I'd like that when a user answers correctly, send a signal to other active user's browser to refresh to the next question. I have been learning about signals in django I learning work with them but I don't now how send the "refresh signal" to client browser. I think that it can do with a javascript code that check if a certain value (actual question) change and if change reload the page but I don't know this language and the information that I find was confused. Can anybody help me? Many Thanks.

• Unit testing with serialization mock objects in C++

  - by lhumongous

  Greetings, I'm fairly new to TDD and ran across a unit test that I'm not entirely sure how to address. Basically, I'm testing a couple of legacy class methods which read/write a binary stream to a file. The class functions take a serializable object as a parameter, which handles the actual reading/writing to the file. For testing this, I was thinking that I would need a serialization mock object that I would pass to this function. My initial thought was to have the mock object hold onto a (char*) which would dynamically allocate memory and memcpy the data. However, it seems like the mock object might be doing too much work, and might be beyond the scope of this particular test. Is my initial approach correct, or can anyone think of another way of correctly testing this? Thanks!
