  • How to add a TabBar to NavigationController based iPhone app

    - by Alex
    I have a simple NavigationController based app. The main window shows a TableView and selecting an item loads a sub-view. I used Interface Builder for UI views. Now I want to add a TabBar to the app. Where do I put it? Do I need a TabBarController? Should it go in the MainWindow.xib, or RootViewController.xib? How do I tie it together with my NavigationController?

  • Best ASP.NET reporting engine with custom reports creation ability

    - by Alex Konduforov
    We need to choose the reporting engine for our ASP.NET application. The main functional requirement is an ability for end users (not programmers, just normal users) to create custom reports. We will be using SQL Server as a database so I am aware of some options: SQL Server Reporting services, Crystal Reports, Active Reports, even WindwardReports. But frankly speaking I've never used any of those except Reporting services and it's quite difficult to choose which one suits the best to customer needs of custom reports creation. Is it possible to get some pros and cons for these options or at least your advice on what would be better to use in this case. Thanks a lot.

  • Testing installation package in OpenSolaris

    - by Alex Farber
    Testing my "configure - make - make install" installation package on OpenSolaris, I found that all required files are placed to expected locations. usr/local/bin contains myprogram file. If I type in command line: /usr/local/bin/myprogram, it is working. However, typing "myprogram" without path does not work. Is /usr/local/bin directory included in OpenSolaris executable path? If not, why autoconfig tools place my executable to this directory? Installation package is created in Ubuntu.

  • in python: can i pass class method as and a default argument to another class method

    - by alex
    i want to to pass class method as and a default argument to another class method, so that i can re-use the method as a @classmethod @classmethod class foo: def func1(self,x): do somthing; def func2(self, aFunc = self.func1): # make some a call to afunc afunc(4) this why when the method func2 is called within the class aFunc defaults to self.func1, but i can call this same function from outside of the class and pass it a different function at the input. i get NameError: name 'self' is not defined

  • Is there a name for a language feature that allows assignment/creation?

    - by Alex Mcp
    This is a bit hard for me to articulate, but in PHP you can say something like: $myArray['someindex'] = "my string"; and if there is no index named that, it will create/assign the value, and if there IS an index, it will overwrite the existing value. Compare this to Javascript where today I had to do checks like so: if (!myObject[key]) myObject[key] = "value"; I know this may be a bit of a picky point, but is there a name for the ability of PHP (and many other languages) to do these checks on their own as opposed to the more verbose (read: PITA) method of Javascript?

  • Best Practice - Validating Input In Simple GUI Application?

    - by Alex
    I'm writing a GUI app with wxwidgets in C++ for one of my programming classes. We have to validate input and throw custom exceptions if it doesn't meet certain conditions. My question is, what is best practice when it comes to this? Should I write a seperate function that checks for errors, and have my event handler's call that function? Or should I do my error-checking in my event handlers? Or does it really matter? Thanks!

  • Workling not running tasks in background

    - by alex
    Hi, I followed the railscast that describes how to get workling running background tasks, but can't get it working. The task runs, but not in the background (it's taking 5 secs before I'm redirected to admin_path). Here is what my code looks like: class AdminWorker < Workling::Base   def test_workling(options)     sleep 5   end end class AdminController < ApplicationController   def test_workling     AdminWorker.async_test_workling     flash[:notice] = "Doing stuff in the background"     redirect_to admin_path   end end What am I doing wrong? How to debug? Thanks!

  • Any best practices with feedback colours?

    - by alex
    I have a few that I think are correct. These are background colours for messages. ERROR: red; INFO: blue; SUCCESS: green; NOT IMPORTANT INFO: yellow Have I got the blue and yellow around the wrong way? Any hex values that are a de facto standard for these? I am curious considering web development, but I think the answers will be agnostic. Here is an interesting thought (I'm sure I've read about it in an article). What colours would the errors be on Target's website, considering all their branding is red?

  • Is there a tool that can refactor this C code correctly?

    - by Alex
    Lets say I have the following code (the array* function are what we use for resizable arrays and they operate on pointers-to-arrays that are null initialized): typedef struct MyStruct { int i; } MyStruct; MyStruct* GetNewMyStruct(int i) { MyStruct* s = malloc(sizeof(MyStruct)); s->i = i; return s; } int SomeFunction(int number, MyStruct *elem) { MyStruct **structs = NULL; int i; for (i = 0; i < number; i++) arrayPush(&structs, GetNewMyStruct(i)); arrayPush(&structs, elem); return arraySize(&structs); } I decide that SomeFunction is too large and I want refactor it. Currently where I work we use VisualAssist X, which has some refactoring capabilities, but when I use it on this it does not work correctly. If I attempt to use it to refactor out the loop, this is what I get: void MyMethod( int number, MyStruct ** structs ) { int i; for (i = 0; i < number; i++) arrayPush(&structs, GetNewMyStruct(i)); } int SomeFunction(int number, MyStruct *elem) { MyStruct **structs = NULL; MyMethod(number, structs); arrrayPush(&structs, elem); return arraySize(&structs); } This is not correct. MyMethod should take a MyStruct ***, not a MyStruct **. This is because the code I'm refactoring takes the address of structs. The result is that the refactored version will always return 1 (since only one object has been pushed into my array) rather than number+1. Are there other tools out there that do this type of refactoring correctly?

  • setting up log4j for gmail, does not recognize System.setProperty("mail.smtps.port", "587")

    - by Alex Le
    Hi I am trying to setup a smtpappender for log4j using gmail as the smtp host. I have read that the port number needs to be 465 or 587 (depending on tls or ssl) and that log4j for some reason doesnt allow a different port to be set inside log4j.properties configuration file. I have read that the best way of doing this would be to use System.setProperty which would change the default javaxmail port to gmail. However when I try to set the System.property entries the the default port still remains as 25 System.setProperty("mail.smtp.starttls.enable", "true"); System.setProperty("mail.smtp.port", "587"); I was wondering if someone could help me out, I am open to suggestions, I just need to smtpAppender to work for gmail, dont really care how to get it to work. Thanks

  • Conceptual website designer ideas?

    - by Alex Tang
    Hi, I'm just wondering if anyone knows of any tool (apart from Visio) to generate visually nice looking website site maps or diagrams of a conceptual website. We're wanting to present some nice diagrams to our client but we're unsure about where to get started - we're all coders, not designers. Visio shapes or stencils are quite old. Just wondered what others in the industry are using!

  • Unix and FreeBSD

    - by Alex Farber
    My final goal is to write the program which can run on the Unix OS. I know that there are many Unix versions, and don't know exactly for now which one I need to support. I cannot install any Unix OS right now. The only thing I can do is to use free OS which is close to Unix as much as possible. Is FreeBSD a good choice for this? I know that there is also OpenBSD, possibly something else.

  • Any books or other resources on Cognos TM1?

    - by Alex
    I have been assigned to a project to create a activity based costing system using Cognos TM1. I'm familiar with a number of other OLAP tools but have zero experience with TM1. Can anyone suggest a good book (searching doesn't turn up anything obvious) or any good online resources?

  • How to catch 'exceptions' for out of order execution in Workflow Foundation 4?

    - by Alex Key
    Hi, I am attempting to model a worklfow using a "WCF Workflow Service" in .net / vs 2010 that needs to handle out of order execution gracefully (but not allow it - if thath makes sense!?) For example I have 2 receive activities one called Initialize and the other called GetValue inside a FlowChart. In most cases Initialize should be called first and GetValue after (as modled in the flow chart). However if GetValue is executed before Initialize I do not want to return an "out of order" exception (although when I look at the WCF test client, I can't actually see an exception). But instead a custom exception saying something like "you must initialize first". In theory I could model this with lots of parallel activities and conditions to check if Initialized / Running / Terminated etc. But the business process I am modelling if very very similar to a state machine... except it must handle people executing things in the wrong order. Ideally I would like to catch the "out of order" exception (thought I don't think it's really an exception as such), check the 'exception' to see which function was attempted to run and then handle it. I have done some research around enabling AllowBufferedReceive. However I don't want to be able to execute out of order (I don't think), but instead give a detailed response if it does happen. I've looked at the new beta state machine template for WF 4 - but i'm not sure if it does what i'm after? I'm not sure if I have the wrong end of the stick, so any help would be greatly appreciated. [EDIT] To help clarify... Sorry it's a tricky one to explain. The standard I am trying to implement (the e-learning standard SCORM RTE) is structured like a state machine i.e. certain functions can only be executed in certain states. However the standard specifies that if the calling clients tries to execute a function that it is not meant to, then a warning should be issued... for example "you cannot use GetValue(), because you have not yet Initialized". Ideally I'd like to structure the workflow as the theoretical state machine and not need to have to use multiple if/else's to handle all the scenarios where something could be executed out-of-order. I'd like to catch a out-of-order exception (but I don't think there is such an exception - as it's not in the debugger) and rethrow it.

  • How to transform vertical table into horizontal table?

    - by avivo
    Hello, I have one table Person: Id Name 1 Person1 2 Person2 3 Person3 And I have its child table Profile: Id PersonId FieldName Value 1 1 Firstname Alex 2 1 Lastname Balmer 3 1 Email [email protected] 4 1 Phone +1 2 30004000 And I want to get data from these two tables in one row like this: Id Name Firstname Lastname Email Phone 1 Person1 Alex Balmer [email protected] +1 2 30004000 What is the most optimized query to get these vertical (key, value) values in one row like this? Now I have a problem that I done four joins of child table to parent table because I need to get these four fields. Some optimization is for sure possible. I would like to be able to modify this query in easy way when I add new field (key,value). What is the best way to do this? To create some StoreProcedure? I would like to have strongly types in my DB layer (C#) and using LINQ (when programming) so it means when I add some new Key, Value pair in Profile table I would like to do minimal modifications in DB and C# if possible. Actually I am trying to get some best practices in this case.
