• What are the difference between Cygwin on windows and real UNIX environment

  - by Tarun

  Hi, I am a C/C++ developer. I have never done C++ programming on UNIX, I have done only on windows. I want to practice C++ on Unix. (Because all big companies ask C++ with Unix). I have a laptop on which i do not want to install any other OS (because i have installed very important software on it and i don't have setups) So, I searched and found CygWin which is Unix emulator for Windows. I am thinking to practice C++ on this. Please help me, how can I practice/learn in more close to the environment(Unix Environment) that is used in Big companies like IBM. What will be the difference between Unix and Cygwin?

• Sending an anonymous email to my own address

  - by N3HL

  I want to send an anonymous email to my own gmail/hotmail/yahoo/any other mail service address (Im not trying to spam or something like that). Why? I have a .NET application and I want to add a "Send log to the developer" feature (attaching the log) using SmtpClient. The fact is I've read like 30+ pages, and found out, i.e. gmail's smtp client doesn't allow anonymous connections, and many other things. The idea is to receive a mail message like this: From: [email protected] (non-existent email really) To: [email protected] (this would be my real address which will recieve the logs attachments) Subject: Issue report nºX (auto-generated) Body: From a textbox Attachments: logs attached Is this possible? If so, how do I achieve it?

• WPF Books in 2010

  - by notJim

  I'm looking to learn WPF, and I'd like to get a book to help in the process. Most of the popular questions on SO regarding actual books are from 2008, and I wanted to see if recommendations for books had changed at all. WPF Unleashed, which seems to be the most popular recommendation, was published in 2006, which is quite a while ago, with the lightening-quick pace that Microsoft has been following with .NET. Does this book still work? For some background, I'm a web developer (using MVC, so MVVM makes sense to me conceptually), looking to make the jump to desktop development. I did C# a while ago, but I'll be picking up a separate C# book to get up to speed on that. I am not interested in Silverlight. I am not necessarily interested in flashy UIs right now, as I'm working on business software but what I am interested in is good, clean, intuitive user interfaces.

• iDevice for Dummies: Can a device be assigned multiple provisions (Personal/Enterprise)?

  - by Alex

  Hi guys, Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is... I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration. I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :) Thanks in advance!

• How does transmission created it's cross plataform app? It has from Qt/Mac to CLI interfaces!

  - by Somebody still uses you MS-DOS

  I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? How did the developers create this software with so many interfaces?

• Android - BaseGameUtil Complicated Import

  - by Fabiow Quixadá

  I've seen many topics in stackoverflow, such as Cannot import BaseGameUtils (Eclipse weirdness) and Android: cannot import BaseGameUtils successfully in Eclipse but none resolved my problem. I've followed https://developer.android.com/google/play-services/setup.html#Setup - the Add Google Play Services to Your Project [Using Eclipse with ADT], I THINK my project correctly references the google play services lib since up to that point nothing wrong happened. Then, following https://developers.google.com/games/services/android/quickstart, I've downloaded BaseGameUtils but when I import the two projects [TypeANumber & BaseGameUtil], they came named as main and MainActivity. I've renamed BaseGameUtil as so and have marked it as lib and imported it to my project through Properties Android Library, but I can't extend extend a class from BaseGameUtil because it's not even suggested. Also, I have not installed Android L and Android 4.4W from SDK Manager in Eclipse, altough I think that's no the case. Can anyone please help in this? Thanks so much in advance

• How do you add < or > to a summary tag in Visual studio?

  - by Tony

  How do you add < (less than) or (greater than) to a summary comment in visual studio? I am in Visual Studio 2008. I have a generic method: public bool IsMemberProtected<T>(Expression<Func<T, object>> expression) Would love to have a summary tag of something like this /// <summary> /// Determines whether a member is protected. /// /// Usage: IsMemberProtected<ExampleType>(x => x.Member) /// </summary> But when I do that, the tooltip for the property no longer works when a developer hovers over the method in code to view the summary tag. Thoughts?

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• Is there a way to load multiple app.configs in memory?

  - by Dave

  I have a windows service that loads multiple "handlers" written by different developers. The windows service exe has it's own app.config which I need. I'm trying to make it so that each developer can provide their own app.config along with their handler code. However, it seems an exe can only have one app.config. However, ASP.NET seems to support nested web.config... That's not exactly what I want, but I don't even know how I would get that to work in a windows service. Anyone come across this before or have any ideas?

• I want my footer to be like this one

  - by Jsmith

  http://developer.apple.com/iphone/library/navigation/index.html?section=Resource+Types&topic=Getting+Started Can I have some code ? This one appears to have a scroller to the right side of the screen and the footer gets sticky to the bottom. But i guess this is a bit different to most of the Sticky footers you're talking about in other threads. I'm going to need some good code to use, as I can't think alike other people and I learn from used code. Iwill be happy to help other people too ...

• Python as your main language. Possible?

  - by Deinumite

  I am currently attending college and the languages that I will 'know' by graduation are C++ and Java. That being said, i am also in the process of teaching myself Python. I know that every programming language has its own pros and cons, but would it be possible to become a python developer out of school? I always have more 'fun' programming in Python than i do in C++ or Java, and I am also in love with Pythons documentation. I know C++ will always be on top in terms of speed, but what would be the benefit of memorizing every javadoc against focusing on Python instead? are there good jobs to be had with Python? edit: also, would it be beneficial for me to look at C# as well? Microsoft is really throwing their support at it so that could be a decent career path as well.

• Using TFS source control - how to remove files

  - by arame3333

  I am a lone developer, and I am now using TFS 2010, having until recently used VSS. I have not found it easy to get any books for beginners to help me use this. So I have now got my project in source control. But when I check in I get references to a number of files that I no longer use. How do I remove files from the TFS Source Control repository? So in the example below you can see lots of files from different projects that I do not want to see.

• C# Multi threading- Move objects between threads

  - by Grant

  Hi, i am working with a winforms control that is both a GUI element and also does some internal processing that has not been exposed to the developer. When this component is instantiated it may take between 5 and 15 seconds to become ready so what i want to do is put it on another thread and when its done bring it back to the gui thread and place it on my form. The problem is that this will (and has) cause a cross thread exception. Normally when i work with worker threads its just with simple data objects i can push back when processing is complete and then use with controls already on the main thread but ive never needed to move an entire control in this fashion. Does anyone know if this is possible and if so how? If not how does one deal with a problem like this where there is the potential to lock the main gui?

• All PHP files getting hacked

  - by nsearle

  Hey All, Like always, just want to say thank you for all of the help and input in advance. I have a particular site that I am the web developer for and am running into a unique problem. It seems that somehow something is getting into every single PHP file on my site and adding some malware code. I have deleted the code from every page multiple times and changed FTP and DB passwords, but to no avail. The code that is added looks like this - eval(base64_decode(string)) - which the string is 3024 characters. Not sure if anyone else has ran into this problem or if any one has ideas on how I can secure my php code up. Thanks again.

• Python: How to quit CLI when stuck in blocking raw_input?

  - by christianschluchter

  I have a GUI program which should also be controllable via CLI (for monitoring). The CLI is implemented in a while loop using raw_input. If I quit the program via a GUI close button, it hangs in raw_input and does not quit until it gets an input. How can I immediately abort raw_input without entering an input? I run it on WinXP but I want it to be platform independent, it should also work within Eclipse since it is a developer tool. Python version is 2.6. I searched stackoverflow for hours and I know there are many answers to that topic, but is there really no platform independent solution to have a non-blocking CLI reader? If not, what would be the best way to overcome this problem? Thanks

• Creating a Pop up and setting its view state before it displays

  - by theringostarrs

  Hi, I am a beginner developer in Flex, and I have been using viewstates lately. I had a couple of custom popup titlewindow components that are initialized using: PopUpManager.createPopUp(this, ContentCreate, true); They both contain view states already, and are very similar so I wanted to combione them into one popup titlewindow and change view state on initialisation of the popup to either the Create version of the popup or the Update. I thought I was being smart haha, but I realized soon after refactoring my code that, I as far as I know I can't pass parameters to the popup to indicate which state I want, if it is created using the PopUpManager. Does anyone know how to pass parameters to the PopupManager, or create the ContentCreate component(TitleWindow) in mxml or code so I can specify the view state?

• SVN user guidelines

  - by Oliver Moran

  I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

• android localization: Is it a good practice to have only needed resource to put in localized folder?

  - by MobileDev123

  Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

• Opening up TCP Sockets in j2ee Webapplication

  - by Gvenez

  Hello, We have to communicate with a C++ component from a J2ee web application and my proposal involved using JMS server to communicate with the C++ component which is located on other machine. However the developer of the C++ component wants me to open up TCP/IP sockets from the webapplication and communicate over XML. My view is that socket programming in web application is error prone and will not scale well since there is a limited amount of sockets that can be opened up. Please let me have your architecture/design preference on using JMS vs TCP/IP sockets. Thank you

• How to identify deadlock conditions in a third-party application?

  - by Imhotep is Invisible

  I am using a third-party application to handle batch CD audio extraction via multiple FireWire attached devices, but the application frequently (though non-deterministically) hangs during the extraction. I suspect that the multithreaded application is deadlocking over some shared resource. The developer, however, suspects the problem lies elsewhere but is not addressing the problem at this time. I would like to be able to do some legwork on my end to a) prove the condition exists and b) ideally point him in the right direction. The problems: while I used to be a programmer, it's been awhile and I need to shake off the dust (last work I did was back in '99 and it was under Solaris, while the application runs under XP). Rather than there being a dearth of information online, there's almost too much to digest. Are there any suggested guides or tutorials that might help me get back up to speed sufficient enough to help identify and/or diagnose the deadlock, or are there tools or approaches that I should study up on to aid me in my task? Many thanks for all suggestions!

• BlackBerry threading model

  - by Rory Fitzpatrick

  I've read a lot of comments mention in passing that the BlackBerry threading model deviates from the Java standard and can cause issues, but no amount of googling has enlightened me on what this means exactly. I've been developing a fairly large business application for the BlackBerry and, although I don't really have any previous experience with Java multi-threaded applications, haven't come across any issue that we've been able to blame on threading, other than what we caused ourselves. Can someone describe exactly how the BlackBerry threading model is different, and how I as a developer should take that into account? Obviously any links on the topic would also be great.
