  • Zend Framework, what $this->_forward is doing

    - by RageZ
    Hello everyone, I would like someone to explain me what _forward is exactly doing, I cannot see if _forward is also rendering the attached view to the action or just executing the action. Also is it possible to pass argument to $this-action in a view script ? More generally my problem is how to code a confirmation page, let's say the user input some stuff and you want to show him confirmation, is forward is mean for that case ? Thanks

  • Python: if key in dict vs. try/except

    - by LeeMobile
    I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

  • QuickGraph - How can I associate an Edge with a Class? (i.e. like you can with a Vertex)

    - by Greg
    Hi, Q1 - How can I associate an Edge with a Class? (i.e. like you can with a Vertex) In my case there are various types of edges I want to be able to model. So my real question I guess is how can I associate some level of data with Edges (e.g. edge type). The graph I was looking at using was: http://quickgraph.codeplex.com/wikipage?title=BidirectionalGraph&referringTitle=Documentation thanks

  • #Define Compiler Directive in C#

    - by pm_2
    In C, I could declare a compiler directive as follows: #define MY_NUMBER 10 However, in C#, I only appear to be able to do this: #define MY_NUMBER Which is obviously useless in this case. Is this correct, or am I doing something wrong? If not, can anyone suggest a way of doing this, either at namespace or solution level? I thought of maybe creating a static class, but that seems to be overkill for one value.

    - by rursw1
    Hi, Is it possible to hold an open TCP connection with a client, while the IP address of the client is externally changed? For example, the connection is establishes against address X, but somewhen while the connection is open, the client-side user asks for IP renew and gets another IP address. Can the connection remains alive in this case? Thanks in advance.

  • Java: How to return single char after string

    - by newSpringer
    I have a file directory which could look like either C:\projects\lab3\test\test.java or C:\projects\assignment3\test\test.java But the "lab3" or "assignment3" can appear anywhere in the directory, it is not a set directory What i want is to check to see if the directory either contains "lab" or "assignment" and get the number that follows. In this case "3" This is what i have so far if(directory.toLowerCase().contains("lab")){ } else if (directory.toLowerCase().contains("assignment")){ } but i do not know how to check for the char straight after the word?

  • Howto check if two hosts are the same

    - by Michael Stoll
    Hi, I just came across an issue, where I had to check if a path points into a windows share. Part of this problem is to check if host A is the same as host B. Where host A and host B can be one of the following {IPv4-Address, IPv6-Address, Hostname, FQDN}. As I do not need to be exact it's enough to resolve and compare the IP-Addresses in my case. But is there, theoretically, a method to check if the hosts are the same?

  • Specify a OneWay Binding in HandleBars - Ember

    - by Miguel Madero
    Is there a way to Specify a OneWay Binding in HandleBars? bind-attr always calls Ember.bind, which always create a two way binding. This seems to be the case for elements that don't even change: <img {{bind-attr class=":class-name-to-always-apply"}}> But even in cases where the element could change, we might have reasons to update it manually (e.g. performance or we don't want to change it on textChanged, but do it manually)

  • Using many mutex locks

    - by hanno
    I have a large tree structure on which several threads are working at the same time. Ideally, I would like to have an individual mutex lock for each cell. I looked at the definition of pthread_mutex_t in bits/pthreadtypes.h and it is fairly short, so the memory usage should not be an issue in my case. However, is there any performance penalty when using many (let's say a few thousand) different pthread_mutex_ts for only 8 threads?

Any help would be appreciated, thanks.

    - by debita
    Hi, I wanted to use this code to send archives with Xmodem: http://www.java2s.com/Code/Java/Network-Protocol/JModemsimplecommunicationsprogram.htm In this case, I want to establish a dialup connection between two computers and send a binary file. But this code doesn't let me set a phone number to dial after i setup the port and before I transfer the file. Is there any way of sharing the port with another application that dials the phone number?

  • initialize a const array in a class initializer in C++

    - by Nathan Fellman
    I have the following class in C++: class a { const int b[2]; // other stuff follows // and here's the constructor a(void); } The question is, how do I initialize b in the initialization list, given that I can't initialize it inside the body of the function of the constructor, because b is const? This doesn't work: a::a(void) : b([2,3]) { // other initialization stuff } Edit: The case in point is when I can have different values for b for different instances, but the values are known to be constant for the lifetime of the instance.

  • Get ahold of session in command object in Grails

    - by UltraVi01
    How can I get the session from within a command object? I have tried: import org.springframework.security.context.SecurityContextHolder as SCH class MyCommand { def session = RCH.currentRequestAttributes().getSession() } This throws java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

  • MS Exam 70-536 - How can you constrain the input before you write any code?

    - by Max Gontar
    Hello! In MS Exam 70-536 .Net Foundation, Chapter 3 "Searching, Modifying, and Encoding Text" in Case Scenario 1 related to regex there is a question: How can you constrain the input before you write any code? I thought it's maybe a in-mind design of regex pattern but it will not really constrain the input, will it? I am not so good in psychokinesis yet! Or maybe the is some other way? Thanks for your time!

  • What are real world examples of when Linked Lists should be used?

    - by oo
    Another programmer was mentioning that they haven't found a use case for using a linked list data structure in any professional software in his career. I couldn't think of any good examples off the top of my head. He is mostly a C# and Java developer Can anyone give some examples where this was the correct data structure to solve a particular real world problem? Related: What is a practical, real world example of the Linked List?

  • Python - How is this snippet working?

    - by orokusaki
    For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?
