  • Why is there only one configuration management tool in the main repository?

    - by David
    How is it that Cfengine does not exist in the Ubuntu (10.04 LTS) Main Repository? I can't find a discussion of this anywhere (using Google). The only configuration management in Ubuntu Main seems to be Puppet. I looked for a wide variety of others as well - all from Wikipedia's list of configuration management tools - and none of them are present in Ubuntu main. I looked for bcfg2, opensymbolic, radmind, smartfrog, spacewalk, staf, synctool, chef - none are present. From my vantage point as a system administrator, I would have expected to find at least bcfg2, puppet, cfengine, and chef (as the most widely used tools). Why is cfengine (or chef and others) not included in Ubuntu main? Why is there only one configuration management tool in Ubuntu main? By the way - the reason this is important in the context of server administration is because Ubuntu main is fully supported by the Ubuntu team with updates and security updates; the other repositories are not.

  • MVC keeping the PartialView in its own context - ignore the main view holding the partial view

    - by Mike
    I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

  • How do interpreters functions written in the class C++ in the main

    - by T_Geek
    Hi I'm working on a project about Data structures. In the first , I wrote everything in main but it sounds like C . But as I learned, I tried to thinkk OOP and do as little as possible in my main() methods. I've implemented some opertation in my class like add,delet,find.it's too easy to implement its . class ARB { private: struct BT { int data; BT *l; BT *r; }; struct BT *p; public ARB(); ~ARB(); void del(int n); void add(int n); }; void ARB::del(int num) { //The code ,don't care about it }; main() { // BTR T; T.add(3); T.add(5); }; But I arrived to the big program How can I define a methode which have to use a binary tree and to get a stack STACK ARB::MyFunct(BT* p) { // The code don't care about it } How can I apply it in the main programme main() { // BT T; T.add(3); T.add(5); STACK S; BT* p S=T.MyFunct(p); // error C2664 cannot convert parametre 1 }; **mention :I implement STACK class

  • QApplication In Non-Main Thread

    - by Boatzart
    I need to exec() a QApplication in a thread that is not main (my GUIs must be plugins that can be dynamically loaded and unloaded at runtime, so I have no access to the main thread). Does anyone know of a (relatively) painless way to hack around Qt's restriction against starting QApplication outside of main? I'm developing in Linux with Qt4 in C++ using gcc4.3.4.

  • Using SetParent to steal the main window of another process but keeping the message loops separate

    - by insta
    Background: My coworker and I are maintaining a million-line legacy application we inherited. Its frontend is written in VB6, and as we're devoting almost all of our resources to converting it to C#, we are looking for quick & dirty solutions to our specific problem. The application behaves in a plugin-ish manner. There are up to 20ish separate ActiveX controls that can be loaded at once in a grid-style layout. The problem is that the ActiveX controls do all of their processing on their own UI thread, and as a lot of it is blocking waiting on network access, the UI gets very soupy. When our hosting C# app loads these controls, it becomes unresponsive because of how many controls are chewing up UI resources doing nothing. To top it off, the controls are fragile and will crash at the slightest provocation. When they are hosted in the main C# app, it creates serious instability. The best my coworker and I have come up with so far is starting a process per ActiveX control. This process, which we call the proxy, is another winforms app. It uses named pipes to communicate with the hosting process. The hosting process creates a window, loads an ActiveX control of our choice (via some reflections & AxHost magic), and tells the main process what its window handle is via the named pipe. The main process uses a combination of SetParent, and SetWindowPos to move the proxy application into itself to emulate a plugin. Size updates are sent via the named pipe. This works well enough until the ActiveX application does some sort of lengthy process and we click around on the main window while it's working. For awhile the main window is responsive, but eventually it becomes unresponsive as the child window waits for its UI thread. How can we keep the child windows on their own complete thread while still getting the benefits of SetParent? (please let me know if anything isn't clear!)

  • Void in main and keeping Dos program from dying

    - by TimothyTech
    Alright, so im using bloodshed complier, first thing i should note is im using a 2001 edition C++ for the aboslute beginner, was there any changes to C++ since 2001 that would effect the validity of this book? i ask because i know php has php5 and now php6 but i havent seen any C++3. now for the reason i asked that, in this code it uses, void main (void) why would i want an arguement to be void? what does this do. But when i run the " void main (void) in my compiler it says that main must have a "int" before it. so i cant have "void" main (void); also, once the code runs through, as long as there isnt a "cin" the program closes. is this normal behavior, is there a better way to stop this besides making a cin at the end of my program.

  • Passing variable from main to Async class

    - by Bigflow
    Somehow, I can't get this done. This is all what I tried till now: Main: private String myState; public String getState() { return myState; } public void setState(String s) { myState = s; } Async: Main appState = ((Main)getApplicationContext()); String state = appState.getState(); Error: No enclosing instance of the type Main is accessible in scope Tried with Helper(Globals) class. public class Globals extends Application{ private String test= "1"; } Main: private Globals mGlobals; mGlobals = new Globals(); mGlobals.test = "2"; //Do Async thing Async: private Globals mGlobals; mGlobals = new Globals(); print mGlobals.test; // (result is 1, should be 2) Also something else, but don't remember good. Tried alot of things (backspace and del buttons are over-used :p ) But I can't get everything working. Async class doesn't have an activity. Code pasted: http://pastebin.com/ikcsdL1p

  • Passing arguments from loading activity to main activity

    - by ZelluX
    I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing. For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits. I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this? Many thanks.

  • Main class passes dbConn obj to all its services, I need to change the dbConn for one of its services. - suggestion for design pattern

    - by tech_learner
    There is this main class and there are several services ( which uses db connection to retrieve data ) These services are initialized in the main class db properties are obtained from the property file and then dbconnection is opened by calling a method dbOpen() written in the main class and the resultant connection object is set to the service objects by iterating through the list of services and by calling setConnection method on the service note: that the services are instantiated in the main class and the main class is not a superclass for services. I also need to mention that there is this recycle db connection scenario only main class is aware of. /** connects to DB, optionally recycling existing connection), * throws RuntimeException if unable to connect */ private void connectDb(boolean recycle) { try { if (recycle) { log.status( log.getSB().append("Recycling DB Connection") ); closeDb(); } openDb(); for ( int i = 0 ; i < service.length ; i++ ) { service[i].setConnection(db); } } One of the service needs to use a different database, what is the best design pattern to use?

  • A program where user enters a string and the program counts the instances of the letters

    - by user1865183
    This is the first C++ program I have ever written and I'm having trouble understanding the order in which operands must be put in. This is for a class, but it looks like I'm not supposed to use the homework tag. Sorry if I'm doing this wrong. This is my input // Get DNA string string st; cout << "Enter the DNA sequence to be analysed: "; cin >> st; This seems to work ok, but I thought I would include it incase this is what I'm doing wrong. This is what I have so far to check that the input is exclusively C,T,A, or G. It runs through the program and simply prints "Please enter a valid sequnce1, please enter a valid sequence2, ... ect. I'm sure I'm doing something very stupid, I just can't figure it out. // Check that the sequence is all C, T, A, G while (i <= st.size()){ if (st[i] != 'c' && st[i] != 'C' && st[i] != 'g' && st[i] != 'G' && st[i] != 't' && st[i] != 'T' && st[i] != 'a' && st[i] != 'A'); cout << "Please enter a valid sequence" << i++; else if (st[i] == c,C,G,t,T,a,A) i++; The second half of my program is to count the number of Cs and Gs in the sequence for (i < st.size() ; i++ ;); for (loop <= st.size() ; loop++;) if (st[loop] == 'c') { count_c++; } else if (st[loop] == C) { count_c++; } else if (st[loop] == g) { count_g++; } else if (st[loop] == G); { count_g++; } cout << "Number of instances of C = " << count_c; cout << "Number of instances of G = " << count_g; It seems like it's not looping, it will count 1 of one of the letters. How do I make it loop? I can't seem to put in endl; anywhere without getting an error back, although I know I'll need it somewhere. Any help or tips to point me in the right direction would be greatly appreciated - I've been working on this code for two days (this is embarrassing to admit).

  • Controls on main window using Visual C++ designer?

    - by PatrickBateman
    Is is possible to draw controls using Visual C++ designer on the main window, in the same way you can design dialogs? I'd preferably like to be able to design the main window controls this way without using MFC, rather than creating them on WM_CREATE. EDIT: I don't want a dialog-based app, just to be able to design the main window graphically similar to what can be done using Windows Forms Designer in .NET?

  • How to set Main Inerface in xCode programatically

    - by Tom Tallak Solbu
    I am using Apples MultipleDetailViews http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html for template as a source for my iPad app. The template is using a splitviewController in the interface builder (MainWindow). In the iPhone/iPad Deployment info of the target, MainWindow is set as the "Main Interface". I want my app to also run on iPhone. This means I need to load a different xib when the app is run on an iPhone. I must then remove "MainWindow" from "Main Interface" because the app will crash when I load on an iPhone due to the splitViewController. The AppDeleagte of the template look like this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.rootViewController = self.splitViewController; [self.window makeKeyAndVisible]; } If I remove "Main Window" from "Main Interface", how do I then need to change the APpDelegate, or maybe I need to change the MainWindow.xib to also work for iPhone?

  • using declarations in main (C++)

    - by Crystal
    Although you wouldn't want to do this, if you have a namespace COMPANY, and a class in that namespace SOMECLASS. Why is it that in the .cpp file, you might define the functions as COMPANY::SOMECLASS::someFunction() {} But in main, you don't do int main() { COMPANY::SOMECLASS::someFunction(); } but instead you declare the namespace and do something like: using COMPANY::SOMECLASS; int main() { someFunction(); }
