  • How can I inherit form and access controls from mother form?

    - by kasia
    Hi, I'm in the middle of writing my project and I have this problem: I try to write a library and I want to use it in my application. In library I have a form with menu strip, tool bar, list view, tree view and etc. Everything in library is protected. In my application I have created the form which inherit form the library. I can change and add new functionality to list view and tree view using designer panel in VS 2008 but I don't have access to menu strip and tool bar, even though they are protected. Why is that so? I will be thankful for some advice.

  • Java Swing - How to access a JComponent of one JPanel from other JPanel, both added to the JFrame?

    - by Yatendra Goel
    I am developing a Java Desktop Application with GUI implemented in SWING. I hava a JFrame. I have added three JPanels on that. One JPanel panel1 has a Start Button. Now I want to disable various componets on other JPanels when a user presses the start button on the panel1. Now how can I access the components of those other panels from panel1. I know that one approach is to first get the container of panel1 panel1.getParent(); Then get the components of the container container.getComponents(); and use them as per need. Q1. Is there any other way by which I can perform the same task? (I think this is the only way) Q2. After getting the components list of the container, how to differentiate one container with other?

  • How can I access the iPhone favorite numbers using Objective C?

    - by Cipri
    Hi! I am writing an application using Objective C and I want to access the iPhone favorites numbers (the ones that can be found in the "Phone" application). I've searched among the properties specific to each contact from the Address Book and I even had a look at the Address Book database, but I couldn't identify which property or field from the database indicates which are the favorite numbers. Since "Phone" is an application installed by Apple on the iPhone I was expecting to find such a property in the database. However, I think that it might be possible that this application stores the favorite numbers independently of the Address Book database. Has anyone encountered this problem before and if yes, could you please clarify this matter for me? Thanks a lot! Cipri

  • Access outer class from inner class: Why is it done this way?

    - by Vuntic
    So most of us know how to access an outer class from an inner class. Searches with those words give oodles of answered questions on that topic. But what I want to know is why the syntax is the way it is. Example: public class A { private class B { public void c() {A.this.d();} } public void d() {System.out.println("You've called d()! Go, you!");} } Why is it A.this.d()? It looks like this is a static field of class A, but... * am confused * Forgive me if this is a repeat; like I said, searches with those words give how-answers.

  • Should I allow my clients to open tickets/access trac?

    - by Mark
    I just installed trac for this project I'm working on, since it's turned out to be a bit bigger than I anticipated. I've added a bunch of tickets with my clients requests which come in the form of emails, phone calls, and meetings. I've also added some stuff I know needs to be done/fixed but they haven't specifically requested. Should I grant them access to trac so they can submit the tickets themselves so I don't have to keep translating (words into tickets) for them? They're very non-technical, so I'm not sure how well it would work; they might open tickets and not provide enough detail, or get confused by all the different fields. If your answer is "no", should I at least let them view the tickets, so they can see what I'm working on, what's been done, hasn't been done? So they can stop calling me to say "xxx doesn't work" when it's already a ticket? (Not that this would work, but I could at least respond "see ticket #42")

  • Should we be giving the client's management team direct access to our git hub repository so that the

    - by SharePoint Newbie
    Hi, We are presently working for a client who is new to working with distributed teams. We have teams spread across India and the UK. Although we have decent project tracking tools (Mingle), would it be a good idea to the give the PM at the client access to our git hub repo. Would this be make it easier for them (see what the devs are working on and an insight into what the team has been developing). I agree that noot all commit messages would make sense to them but would this be a good way to boost their confidence in what we are doing? They already can check out our fortnightly releases on our QA and UA environments, but this still is behind dev by 5-6 days. Also, is there any reporting for git hub which makes it easier for PM types to make sense of it all? Thanks

  • Which tool can list writing access to a specific variable in C?

    - by Lichtblitz
    Unfortunately I'm not even sure how this sort of static analysis is called. It's not really control flow analysis because I'm not looking for function calls and I don't really need data flow analysis because I don't care about the actual values. I just need a tool that lists the locations (file, function) where writing access to a specific variable takes place. I don't even care if that list contained lines that are unreachable. I could imagine that writing a simple parser could suffice for this task but I'm certain that there must be a tool out there that does this simple analysis. As a poor student I would appreciate free or better yet open source tools and if someone could tell me how this type of static analysis is actually called, I would be equally grateful! EDIT: I forgot to mention there's no pointer arithmetic in the code base.

  • How to backup Servers to an SSH-Host with low traffic and access to versions and encryption?

    - by leto
    Hello, I've not run backups for the past dont't remember anymore years for my personal stuff until waking up lately and realising contrary to my prior belief: Actually. I care! :) Now I have a central data server at home where I want to attach an external media to, to which I want to save backups of my most important stuff, like years of self-written scripts, database dumps, you name it. I've tinkered with rsync+ssh over the last two years, also tried tar over ssh, but don't know the simplest and most easy to maintain way to do it yet. Heres my workload: A typical LAMP-Server (<5GB Data) which I'd like to backup fully so lots of small files connected via 10Mbit My personal stuff (<750GB Data) from a Mac connected via GE My passwords in an encrypted container (100Mb) from OpenBSD connected via serial-PPP My E-Mail from the last ten years (<25GB) as Maildir which I need to keep in readable format Some archives (tar.*) which I need to backup only once and keep in readable format (Deleted my ideas, as I'm here for suggestions) What I need: 1. Use an ssh-tunnel for data transfer 2. Be quick with lots of small files 3. Keep revisions 4. Be sure the data I save is not corrupted 5. Intelligent resume functions and be able to deal with network congestion :) 6. Compressed and optionally encrypted storage 7. Be able to extract data from backup easily (filesystem like usage would be nice) How would and with what software would you backup this stuff? Hints to tools that can help solve only part of my problem (like encryption) also greatly appreciated. Greets

  • Best practice to detect iPhone app only access for web services?

    - by Gaius Parx
    I am developing an iPhone app together with web services. The iPhone app will use GET or POST to retrieve data from the web services such as http://www.myserver.com/api/top10songs.json to get data for top ten songs for example. There is no user account and password for the iPhone app. What is the best practice to ensure that only my iPhone app have access to the web API http://www.myserver.com/api/top10songs.json? iPhone SDK's UIDevice uniqueueIdentifier is not sufficient as anyone can fake the device id as parameter making the API call using wget, curl or web browsers. The web services API will not be published. The data of the web services is not secret and private, I just want to prevent abuse as there are also API to write some data to the server such as usage log.

  • Why this friend function can't access a private member of the class?

    - by Alceu Costa
    I am getting the following error when I try to access bins private member of the GHistogram class from within the extractHistogram() implementation: error: 'QVector<double> MyNamespace::GHistogram::bins' is private error: within this context Where the 'within this context' error points to the extractHistogram() implementation. Does anyone knows what's wrong with my friend function declaration? Here's the code: namespace MyNamespace{ class GHistogram { public: GHistogram(qint32 numberOfBins); qint32 getNumberOfBins(); /** * Returns the frequency of the value i. */ double getValueAt(qint32 i); friend GHistogram * Gbdi::extractHistogram(GImage *image, qint32 numberOfBins); private: QVector<double> bins; }; GHistogram * extractHistogram(GImage * image, qint32 numberOfBins); }

  • How should I be storing objects that I wish to access in reverse order of the way I placed them in

    - by andrew hicks
    I'm following this guide here: http://www.mazeworks.com/mazegen/mazetut/index.htm Or more specficially create a CellStack (LIFO) to hold a list of cell locations set TotalCells = number of cells in grid choose a cell at random and call it CurrentCell set VisitedCells = 1 while VisitedCells < TotalCells find all neighbors of CurrentCell with all walls intact if one or more found choose one at random knock down the wall between it and CurrentCell push CurrentCell location on the CellStack make the new cell CurrentCell add 1 to VisitedCells else pop the most recent cell entry off the CellStack make it CurrentCell endIf endWhile Im writing this in java, My problem is. How should I be storing my visited cells, So that I can access them from reverse order of when I placed them in. Like this? List<Location> visitedCells = new ArrayList<Location>(); Then do I grab with visitedCells.get(visitedCells.size()-1)? Location stores the x, y and z. Not something Im trying to ask you.

  • Understanding IUSR_<machine> account

    - by liho1eye
    Namely how is setting read/write permission for this account different from giving read/write access in the IIS (Windows 2003, so it should be IIS6 if I am not mistaken). Here is the issue: It looks like we had a security sweep and as a part of that IUSR account lost write access everywhere. A whole bunch of legacy ASP sites didn't like that at all... My very surfacish understanding is that it is enough to deny write access in the IIS console to protect a website from someone just dropping random files into it, and IUSR access only has effect on the application scripts running server side, and thus can be safely given write access back. edit: The applications in question obviously require write access to their own web folders, otherwise this wouldn't be an issue at all. Question is how to configure IIS/application to both satisfy security and make them work. My first instinct was to change account which is used to run the app pool. However that is already set to NETWORK_SERVICE, and that guy already has full access to folders in question.

  • Possible to access all Movie clips on a layer, on timeline, through stage ?

    - by azislo
    I have a code ... var selection:Array = new Array(); var diplayObjCont:* = stage; // The rectangle that defines the selection in the containers coordinate space. // Loop throught the containers children. for(var a:int; a<diplayObjCont.numChildren; a++){ // Get the childs bounds in the containers coordinate space. var child:DisplayObject = diplayObjCont.getChildAt(a); selection.push(child); } trace(selection); that returns just [object MainTimeline] So, can I access layers on this MainTimeline to get all Movie Clips on this layer ? So I can do a simple operation "A_1_2.buttonMode = true;" to all my MC's (in an array for example) without writing every line (lot of MC's on layer and lot of lines).

  • Is it possible to access JSON properties with relative syntax when using JSON defined functions?

    - by Justin Vincent
    // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(this.message); } }; myCode.helloWorld(); The above JavaScript code will alert 'undefined'. To make it work for real the code would need to look like the following... (note the literal path to myCode.message) // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(myCode.message); } }; myCode.helloWorld(); My question is... if I declare functions using json in this way, is there some "relative" way to get access to myCode.message or is it only possible to do so using the literal namespace path myCode.message?

  • Easy one? Access an object's property by using a variable in C# [closed]

    - by ozke
    Possible Duplicate: Property Name and need its value Hi, This one should be easy for most people. I'd like to access a normal variable in an object (let's say example) by using a variable value. E.g.: I have a an array with a list of variable names and I want to get the information from the object by using them. Obviously this is wrong: string[] variable_names = new string[] {"name", "surname"}; myObject.variable_names[0] = 1; myObject.variable_names[1] = 1; In other languages (not C#) I use: myObject[variable_names[0]] = 1; I know the example looks stupid but it was just a way of explaining it. Thanks in advance :)

  • Store product data in session variable or access db every time?

    - by JakeTheSnake
    I have my database storing lots of information about products (year, name, release_date, volume, etc. etc.). I currently load all of the products once and store them in a session variable - right now there's only 8 products but the list will grow as time progresses. The reason why I did this was to (perhaps foolishly) save HDD reads every time the products page was accessed. Am I shooting myself in the foot by storing this information in the session?
