• How to read from port#### on home IP 127.0.0.1 [SOLVED]

  - by Ree

  I have a program that sends data to the home IP to the port####. I want to access this and make it readable data. Maybe in C#? I haven't tried doing this before and I have only a vague idea of doing sockets. Any ideas as to how I can manage this? Thanks - Ree EDIT The program I'm trying access is a UDP. Therefore it's a UDP port reader I need to incorporate on another program. "####" < is just any random number. SOLUTION: http://msdn.microsoft.com/en-us/library/tst0kwb1.aspx

• Trimming strings in Go

  - by user1263980

  I'm trying to read an entire line from the console (including whitespace), then process it. Using bufio.ReadString, the newline character is read together with the input, so I came up with the following code to trim the newline character: input,_:=src.ReadString('\n') inputFmt:=input[0:len(input)-2]+"" Is there a more idiomatic way to do this? That is, is there already a library that takes care of the ending null byte when extracting substrings for you? (Yes, I know there is already a way to read a line without the newline character in go readline -> string but I'm looking more for elegant string manipulation.)

• Change Message on Sony Reader to “Do not disconnect”

  - by Martin Broerse

  When I connect a Sony Reader to an USB port “USB connected” is shown on the Reader. When the Sony “Reader Library” software is started this message changes to “Do not disconnect”. I want to implement this in a software tool to. There seems to be no file locked. Perhaps it is done via ebookUsb.dll. Does anybody know how this is done from any programming language? I like to see an example.

• As a Web Developer, how complicated is your average job compared to this?

  - by Daniel S

  I'm 16 years old, and I've recently started to do freelance jobs. I've been playing with PHP since I was 12 and think that I can code reasonably well. So far, I've created a library for fetching info from LinkedIn profiles and some WordPress plugins. However, right now this client wants me to convert an HTML template into a WordPress theme for use as a website. I feel this is a tad easy. As professional web programmers, are most assignments harder than this?

• Compilation failing - no #include - boost

  - by jwoolard

  Hi, I'm trying to compile a third-party library, but g++ is complaining about the following line: typedef boost::shared_ptr<MessageConsumer> MessageConsumerPtr; The strange thing is, there is no #include directive in the file - and it is clearly supposed to be this way; there are about 60 files with the same (or very similar) issues. Clearly if there was an #include directive referencing the relevant boost header this would compile cleanly. My question is: how can I get g++ to somehow automagically find the relevant symbol (in all instances of this issue, it is a namespace that can't be found - usually std:: or boost::) by either automatically processing the relevant header (or some other mechanism). Thanks. Edit My current g++ call looks like: g++ -fPIC -O3 -DUSING_PCH -D_REENTRANT -I/usr/include/boost -I./ -c MessageInterpreter.cpp -o MessageInterpreter.o

• monitoring streaming server and display throughput

  - by I__

  Scenario: laptop (running RHEL 5.3 / 5.4) with Wi-Fi allowing incoming connections (the laptop is the DHCP server and default gateway of any device that connects to it). The laptop has a streaming server installed (my app). I need to program an app that could monitor this link (device / streaming server) and display the throughput. More importantly, I need this app to be able to throttle the throughput. Think WANem but as an app, or netlimiter but (way) simpler and for RHEL. If you need clarifications, let me know. is there a library that could help me? i've done mostly windows business applications programming, and i have no clue about this stuff. please help me to get started!

• JButtons don't imediatly change on mouse event

  - by out_sider

  I'm using the java swing library to develop a board game called DAO. The problem is that after the human player makes its move, by clicking on the JButton with the piece image that he wants to play, I call the computer AI routine but inside the mouse event function. By doing this only when the function returns, the computer ends its turn, do the JButtons refresh their Images (setIcon comes in). I'd like to know how can I force the JButtons to change their image at the moment they are clicked and not only when the mouse event function ends (as I need to handle data inside it). I've tried all of this myButtons[i][j].setIcon(xIcon); myButtons[i][j].revalidate(); myButtons[i][j].repaint(); myButtons[i][j].validate(); None worked. Thx in advance

• Rails: What's the suggested approach to retrieve xml from an outside source

  - by Syrahn

  Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

• Inter-project dependencies

  - by Mike Hordecki

  Hello! I'm doing some Delphi (2010) work this summer, and I've stumbled upon this problem: My project consists of reusable backend library and a bunch of GUIs that tap into its interface. In this circumstances I've decided to make the backend and GUIs separate projects within single project group (I hope my train of thought is correct). The problem is, how can I include units from the backend in a GUI project? I've tried to modify Project Options > Directories and Conditionals but compiler still complains about being unable to find proper .dcu's. Any ideas? Your help will be appreciated.

• FILE Type Not Recognized in MFC

  - by Chicko Bueno

  I'm using FILE type in my MFC project but after compiled, it shows the following errors: Error 23 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Error 24 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Error 22 error C2146: syntax error : missing ';' before identifier 'm_pFileW' Those errors are referring to this code: FILE *m_pFileW; Did I missing any library header to use FILE syntax? Do I need to use different approach and replace FILE syntax? This errors are only generated when I placed it into my MFC project. This is not happening in C++ Console. Please help. Thank you.

• Have anyone ever create/manipulate a table application from the ground up/scratch?

  - by Darwin

  Have anyone ever create/manipulate a table application from the ground up/scratch? I want to create a table using flash AS 3. I like to have the features like to the MS Studio Web Developer option. The options are create a table, merge cells, split cell, resize columns, delete cell, delete row, delete column etc... I think this is going to be very complicated thing to do. I think the only way to do it is to build it from the ground up because I don’t think Flash has the library/component for it. I was able to create rows and columns by creating the # of rectangles listed it from the left to the right and move the next coordinate for the next row. Now the most challenging this is to manipulate it. This is the must have feature on my website and we don’t want use Javascript to create table on the server side to create the table.

• Decoding MIME (HTML+Attachments)

  - by MH

  I'm planning to write an application that should handle incoming mails. Basically it will act more like a ticketing system than a webmail, so I'm only interested in receiving emails, and not sending them. I have made a simple prototype that downloads mails and displays the text with downloadable attachments in a web page, but handling mails from Outlook and others is more complicated. I have looked at some of the open source ticketing systems out there, but most of the code is tied to the system and is hard to separate. Is there a library that understands "rich" mail and makes this job simpler? Preferably in Python, Java, Ruby or Perl. I'm also open to suggestions for any command line mail clients that can be used for this, since the system will not receive large amounts of mail and can afford to launch external processes.

• Dealing with video (DVDs, .avi .mkv) in Java

  - by berry120

  After looking around for a decent library for playing videos in Java, I've come unstuck. Everyone around is screaming not to use JMF because it's outdated, old and requires the user to install it, other alternatives such as VLCJ seem good if they work but are still relatively unstable and rely on hefty amounts of native code, and as for dealing with DVDs, I haven't found a single option available! Weighing up my options at the moment, it seems like realistically it's either JMF (despite its disadvantages) or waiting until JavaFX 2.0 comes out and then using that. VLCJ just seems too unstable which isn't really something I can live with. Are there any sensible options other than the ones I've listed above, and what would you go for? I'm not against native code per-se, but it has to be reliable and work on Windows, Mac and Linux.

• What license (eg. BSD, GPL, etc) can I use for an open source app that can be used commerically, for free?

  - by Pure.Krome

  Hi folks, I've got an application on Codeplex. It's based on some other free open source code which comes with a BSD license. As such, people keep asking if they can use my open source code/library in their commercial apps. I want them to be able to, provided they give credit to the source app (the project which i based my code, from .. and that has the BSD license) and also my code. They can take my code and do whatever (fork it, etc).. Just make sure they give credit, of course. So - what license could I use? Currently, I've set it to be GPL .. so is that ok? NOTE: Yes yes, I know that any answers are not from a lawyer and it's just all personal thoughts and I need to consult a special lawyer if I want some professional advice, etc. etc. I'm happy to take that risk, here.

• python challenge, but for C++

  - by davidthepsycho

  Does anyone know any site or book that presents problems like python challenge, but for C++? When I think python challenge, I do not mean only a set of problems to be solved with C++ (for that I could probably use the same problems of python challenge), but rather problems that will probably be best solved using C++ STL, special features of the language, etc. For example, there is one python challenge that is specifically designed to teach you how to use pickle, a serializing library for python. Until now, I only know programming contests problems, but they could also be solved with C, java or other languages.

• Is it possible to achieve string localization inside of a statically linked lib?

  - by user3696003

  I am working on building an SDK which will be built out as a statically linked library that third party applications can then drop in to their applications. Inside of this SDK, I was looking to be able to perform some "localization." Basically, I would like for the code in my SDK to be able to access some ".string" files to perform some string lookup and language translation capabilities. Then I could propagate these strings outward to implementing App layers through my exposed API's. Is this even possible? I thought it was but now that I have actually been trying, I am seriously having doubts.

• How can I combine multiple iPhone applications in to one application?

  - by Toret

  At the moment I have 2 completed iPhone applications. Both these applications must be contained in to one application. I can't have multiple apps on the app store and to avoid confusion among people using these apps I must have them contained to a single application that gives the user the capability to launch any application in the wrapper. How can I go about doing this. Some of the ideas that crossed my mind are: Building a Framework, or building a library. But Im not even sure if I'm heading in the right direction.

• Amazon SimpleDB - Is there a way to list all Attributes in a Domain?

  - by beer-drinker

  Hi, I'm using C# and the AWSSDK library form Amazon to test a few things in SimpleDB. All going well so far. However, I am trying to come up with a neat way of retrieving all Attributes that are applicable to a Domain. This is proving to be tricky without having to retrieve an Item, and obviously I can get the list of attributes then. But what if I have 100,000 Items in a Domain. Let's say the first 70,000 Items in a "Person" Domain have: FirstName, LastName, Address And then I hit a Item that has FirstName, LastName, Address, Phone And then I hit another Item around the 80,000 mark which has: FirstName, LastName, Email, Phone In the above example, for the Person Domain, how would I get a list that contains: FirstName, LastName, Address, Email, Phone ...without performing a ridiculous number of select statements? Many thanks!

• PHP GD issues with ImageCreateTrueColor and PNGs

  - by DrPheltRight

  I am resizing PNG images using the GD image library function ImageCopyResampled(). It all works fine, I can even keep alpha blending transparency with the use of ImageCreateTrueColor() rather than using ImageCreate() to create the resized image. The problem is, that if I use ImageCreateTrueColor() rather than ImageCreate() the file size of PNG files increases from something like 80kb to 150kb. If I use ImageCreate() the file size stays around the same size, but colors screw! So my question is, how can I retain alpha blending when resizing PNG images without increasing the file size? Oh and I am reducing the dimensions of the PNGs.

• Using Silverlight with Existing Application

  - by Silverlight_noob

  This seems like a very basic question but I couldn't find any help on web. If you could provide some link or steps to do this. I have created few basic Silverlight applications which are working fine standalone. I also have a basic ASP.NET application with a solution with around 10 Class Library Projects and 1 website. I want to create a small popup which will have some funtionality using Silverlight. How should I go about creating this application and how to integrate it with my existing application for it to show as a link. I would not want that link to open another application/site. Thanks.

• How to set AssemblyInfo.cs based on the tfs project build number?

  - by Ahok Rudraraju

  The project is hosted on a tfs server and I need to access the build number which I assume is automatically generated when ever you build a project. I need to retrieve that build number and display it on the web pages so that QAs and testing people know exactly which build they are working on. I found how to create customize build numbers in the following link: http://msdn.microsoft.com/en-us/library/aa395241(v=vs.100).aspx but it dose not solve my problem as I do not have access to the build definition file. I am looking for some kind of post deployment task which can access the build number or may be generate one and probably write it down to a file, from where I can read it. I don't know if that makes any sense as this is my first time working on .Net

• C++ Inheritance Question

  - by shaz

  I have a base class MessageHandler and 2 derived classes, MessageHandler_CB and MessageHandler_DQ. The derived classes redefine the handleMessage(...) method. MH_DQ processes a message and puts the result in a deque while MH_CB processes the message and then executes a callback function. The base class has a static callback function that I pass along with a this pointer to a library which calls the static callback when a new message is available for processing. My problem comes when I am in the static callback with a void * pointing to either a MH_DQ or a MH_CB. If I cast it to the base class the empty MessageHandler::handleMessage(...) method is called, rather than the version in the appropriate derived class. What is the best way to address this situation from a design perspective and/or what language features might help me to implement a solution to my problem? Thanks in advance!

• Building a jar to be used in an eclipse PDE?

  - by tul

  I have written an application that use a third party library. I have then packaged this as an executable jar using the maven-assembly-plugin (producing a jar with all dependencies including some of the third-party jars). Next I need to add this jar to a PDE project so it can be launched from eclipse. But to make this work I need to add some of the thirs-party dependencies to my PDE project which is already located in the packaged jar. So I get duplicated dependencies. Any ideas on how to avoid this? Or suggestion to documentation that describes how this is done properly?

• How to automatically trigger the App Object initialization in Powerpoint ?

  It is said here: http://msdn.microsoft.com/en-us/library/aa211599%28v=office.11%29.aspx Before the procedure will run, you must connect the declared object in the class module (App in this example) with the Application object. You can do this with the following code from any module. Dim X As New EventClassModule Sub InitializeApp() Set X.App = Application End Sub Run the InitializeApp procedure. Run HOW ? By hand ? I want it to automatically run when opening the powerpoint rather. Is there any way ?
