• Does a PHP library exist to work with PRC/.mobi files?

  - by Chris Clarke

  I'm writing a WordPress plugin to create an eBook from a selected category in most major eBook formats. I would like to support MobiPocket since that's the format used by the Kindle but I'm not sure how to go about it. From what I've read .mobi files are actually Palm Resource Databases (PRC) but I haven't been able to find a PHP class to work with these. I thought about using exec along with KindleGen but that would be undesirable as it would complicate initial setup. I've also thought about hosting a web service somewhere and using XML-RPC to accomplish this but that also complicates things. My question is: is there a PHP class/library (PHP-only preferred) that can work with PRC or even better, a class that specialises in creating MobiPocket ebooks? (needs to be open source since I'm releasing under the GPL) I've tried searching but haven't been able to find anything.

• Boolean Code Clarity - which style to use? [closed]

  - by Anonymous

  I was wondering what style others' use when writing conditional statements that include boolean types. Currently I'm caught between using two styles. bool foo; if (foo == true) if (foo) if (foo == false) if (!foo) Obviously the first set is a bit more obvious. However, when combining conditions it could get a bit clunky. if (foo == true || blah == false || abc == true) if (foo || !blah || abc) Switching between one style for short conditionals and the other for long conditionals seems like inconsistent coding so it seems like I'd have to choose between one or the other. What do you prefer or consider better style and why?

• Essential Training Topics for Supervisors of ASP.NET Developers

  - by Dave Johnson

  I have a co-worker who supervises a group of ASP.NET developers who are doing lots of ASP.NET/SQL Server apps. My co-worker was very technical at one time, but his last programming assignment was writing Fortran code in the 1980s. He has asked me to help him gain a deeper knowledge of ASP.NET Web application development to equip him in his supervisory role. I will be spending an hour every other week with him providing training, and he will probably not have a lot of time to commit otherwise. What would you recommend as topics to cover, tutorial resources, etc. so that I can help him get up to speed in his role as a supervisor of ASP.NET developers?

• The ultimate .NET file and directory utility library?

  - by Serge van den Oever

  I find myself writing file and directory utility functions all the time, and I was wondering if there is good file and directory library that already implements a more extensive set than available by default in System.IO. The kind of functions I'm looking for is things like: public static void GetTemporaryDirectory() { string tempDirectory = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()); Directory.CreateDirectory(tempDirectory); return tempDirectory; } public static void CreateEmptyFile(string filename) { File.Create(filename).Dispose(); } public static void CreateEmptyFile(string path, string filename) { File.Create(Path.Combine(path, filename)).Dispose(); } public static void CreateDirectory(string path) { Directory.CreateDirectory(path); } public static void CreateDirectory(string path, string childpath) { Directory.CreateDirectory(Path.Combine(path, childpath)); }

• ASP.NET (AJAX) UI Design Tools for Artistically Challenged?

  - by davemackey

  I'm building an application but I'm artistically challenged and I'd rather not spend my time writing widgets (e.g. ability to collapse/expand/close/drag-drop) if there is already controls available. I've worked with the Microsoft AJAX Control Toolkit - but these tools still require a lot of work to get a working widget (which in my case, won't look too pretty). The CollapsiblePanel is pretty nice - but then you have to program in the minimize button, close button, maximize button, etc. Looking for suggestions that will help me design better UI faster...

• Why doesn't CSS support constants?

  - by Adiel Mittmann

  CSS has never supported constants or variables directly. Whenever I'm writing code like this: span.class1 { color: #377fb6; } div.class2 { border: solid 1px #377fb6; /* Repeated color */ } I wonder why such a seemingly simple feature has never made it into the standard. What could be hard about implementing a scheme whereby we could avoid repetition, something like this: $theme_color1: #377fb6; span.class1 { color: $theme_color1; } div.class2 { border: solid 1px $theme_color1; } I know there are workarounds, like using a class for each color or generating CSS code from templates, but my question is: given that CSS is so rich and complex, why weren't CSS constants ever introduced?

• GUI Control For Audio Presentation

  - by Boris

  I need GUI control for audio file presentation. The language is not very important but it should run on windows platform. I should be able to :- load the file play the sound put and move markers across the audio bar. it would be nice if it can load itself from RTP wireshark captures (and not wav files). An example may be seen in audacity (may be someone even had an experience extracting it from there). Writing nyquist scripts in audacity is not a good option because I have to operate on RTP captures and not on raw sound samples. Another example of such control is wireshark RTP analyzer. Any advise?

• Use of LOC to determine project size

  - by acidzombie24

  How many lines of code (LOC) does it take to be considered a large project? How about for just one person writing it? I know this metric is questionable, but there is a significant difference, for a single developer, between 1k and 10k LOC. I typically use space for readability, especially for SQL statements, and I try to reduce the amount of LOC for maintenance purpose to follow as many best practice as i can. For example, I created a unified diff of the code I modified today, and it was over 1k LOC (including comments and blank lines). Is "modified LOC" a better metric? I have ~2k LOC, so it's surprising I modified 1k. I guess rewriting counts as both a deletion and addition which doubles the stats.

• What parallel programming model do you recommend today to take advantage of the manycore processors

  - by Doctor J

  If you were writing a new application from scratch today, and wanted it to scale to all the cores you could throw at it tomorrow, what parallel programming model/system/language/library would you choose? Why? I am particularly interested in answers along these axes: Programmer productivity / ease of use (can mortals successfully use it?) Target application domain (what problems is it (not) good at?) Concurrency style (does it support tasks, pipelines, data parallelism, messages...?) Maintainability / future-proofing (will anybody still be using it in 20 years?) Performance (how does it scale on what kinds of hardware?) I am being deliberately vauge on the nature of the application in anticipation of getting good general answers useful for a variety of applications.

• I've created a database table using Visual Studio for my C# program. Now what?

  - by Kevin

  Hi! I'm very new to C#, so please forgive me if I've overlooked something here. I've created a database using Visual Studio (add new item service-based database) called LoadForecast.mdf. I then created a table called ForecastsDB and added some fields. My main question is this: I've created a console application with the intention of writing some data to the newly created database. I've added LoadForecast.mdf as a data source for my program, but is there anything else I should do? I saw an example where the next step was adding a "data diagram", but this was for a visual application, not a console application. Do I still need to diagram the database for my console app? I just want to be able to write new records out to my database table and wasn't sure if there were any other things I needed to do for the VS environment to be "aware" of my database. Thanks for any advise!

• Setting up a Git remote with a truncated history

  - by drg

  I am in the midst of doing some non-standard, probably doomed, experiments on a git repository. The goal is to create a remote repository with a truncated history which can still share commits with an internal repository which has a full history. I've had some success using a graft to connect the public history with the private history - when I push from my internal repository, only the post-graft contents are included. So my main question is: what is the simplest way of taking a commit, eliminating its parent and writing a graft in place of the parent? A more general question: is what I'm trying to do going to cause me pain in the long run, do you know if there's a better way?

• what's the UNC path for local computer from a remote machine ?

  - by KaluSingh Gabbar

  I am writing a small utility program in IronPython to install applications on remote machine using managementclass which uses WMI. Now, the script would install an application on Machine_B from Machine_A, it works fine as long as you have the msi file on the local drive of the Target machine (Machine_B, in this case). I want to be able to do same thing with .msi file being on the Host (Machine_A) machine. network_scope = r"\\%Machine_B\root\cimv2" scope = ManagementScope(network_scope, options) scope.Connect() mp = ManagementPath("Win32_Product") ogo = ObjectGetOptions() mc = ManagementClass(scope, mp, ogo) inParams = mc.GetMethodParameters ("Install") inParams["PackageLocation"] = r"C:\installs\python-3.1.1.msi" inParams["AllUsers"] = True retVal = mc.InvokeMethod ("Install", inParams, None) print retVal ["ReturnValue"].ToString() PROBLEM : [Machine A] --- Where I am running the script, and want to host the .msi file [Machine B] --- where I want to install the application So, How can I define the UNC path for local machine ? what will be inParams["PackageLocation"] = ??

• when to use strncpy or memmove

  - by robUK

  Hello, gcc 4.4.4 c89 I have always used strncpy to copy strings. I have never really used memmove or memcpy very much. However, I am just wondering when would you decide whether to use strncpy, memmove, or memcpy? The code I am writing is for a client/server application. In the documentation they use bcopy. However, could I do the same with the others? bcopy((char*)server->h_addr, (char*)&serv_addr.sin_addr.s_addr, server->h_length); Many thanks,

• How do I prevent WIX CAQuietExec from logging the command line?

  - by Noel Abrahams

  In order to prevent command windows from popping up during installation I am using the WIX built-in custom action CAQuietExec. First I define the command line: <CustomAction Id="A01" Property="QtExecCmdLine" Value="&quot;MyExe.exe&quot; /password [PASSWORD]" /> NB: The PASSWORD property is defined as Hidden. This prevents the Windows installer from writing the property value to the log. Then I call into the embedded WIX extension: <CustomAction Id="A02" BinaryKey="WixCA" DllEntry="CAQuietExec" Execute="immediate" Return="ignore" /> This works fine. However, when I go to the temp folder and open up the MSI log I see the following entry: CAQuietExec: "C:\Program Files\MyExe.exe" /password INCLEARTEXT I.e. the password is displayed in clear text and not hidden. How do I prevent the CAQuietExec from logging the password in clear text?

• Is there a way to find out if an iPhone / iPad app is installed already?

  - by eerok512

  I'm writing a freeware version of an app and would like to check if a user already has the unfree version installed, and print a message whose contents are conditional on the results of the installation check... anybody know if this is possible? the closest I've come to a solution is to make use of the CFPreferencesSetValue API with a kCFPreferencesAnyUser / kCFPreferencesCurrentHost pairing... I haven't tried it, but based on the documentation it sounds possible. however in my current specific situation this API will not be able to solve my problem, because I want to check for the presence of an app I wrote 4 months ago that didn't write any data to the CFPrefs registry... because back then I didn't know of it nor did I foresee this situation arising... the only way CFPrefs can assist me is in future apps now that I know it exists :) so I'm wondering if there are other ways to do it? any help will be appreciated :)

• Can't send key to window with SendMessage

  - by user297313

  I'm writing a C program under Windows that should send an ENTER key to a dialog box to close it automatically. I retrieve the handle to the top level window I'm interested in (by means of EnumDesktopWindows()) and then try to send an ENTER key using SendMessage (note also that closing the window by sending WM_CLOSE works fine). None of the following works: SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 0 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYDOWN, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_CHAR, VK_RETURN, 1 ); SendMessage( hTargetWindow, WM_KEYUP, VK_RETURN, 1 ); and so on... As a possibly simpler scenario, I also tried to send an ascii key to, say, notepad. How is this supposed to work? Thanks in advance

• Multiple Servers with identical services

  - by Jerry Bailey

  I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

• removing a line from a text file?

  - by Blackbinary

  Hi all. I am working with a text file, which contains a list of processes under my programs control, along with relevant data. At some point, one of the processes will finish, and thus will need to be removed from the file (as its no longer under control). Here is a sample of the file contents (which has enteries added "randomly"): PID=25729 IDLE=0.200000 BUSY=0.300000 USER=-10.000000 PID=26416 IDLE=0.100000 BUSY=0.800000 USER=-20.000000 PID=26522 IDLE=0.400000 BUSY=0.700000 USER=-30.000000 So for example, if I wanted to remove the line that says PID=26416.... how could I do that, without writing the file over again? I can use external unix commands, however I am not very familiar with them so please if that is your suggestion, give an example. Thanks!

• IWebBrowser2: how to force links to open in new window?

  - by Rob McAfee

  The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

• Interview question: How do I detect a loop in this linked list?

  - by jjujuma

  Say you have a linked list structure in Java. It's made up of Nodes: class Node { Node next; // some user data } and each Node points to the next node, except for the last Node, which has null for next. Say there is a possibility that the list can contain a loop - i.e. the final Node, instead of having a null, has a reference to one of the nodes in the list which came before it. What's the best way of writing boolean hasLoop(Node first) which would return true if the given Node is the first of a list with a loop, and false otherwise? How could you write so that it takes a constant amount of space and a reasonable amount of time? Here's a picture of what a list with a loop looks like: Node->Node->Node->Node->Node->Node--\ \ | ----------------

• Connecting .NET to Common Lisp

  - by JPanest

  I have a fairly involved LispWorks Common Lisp module that sits atop some .NET modules via RDNZL. It has come up that I need to expose some of its functionality to some other .NET applications, and I'm not sure the best (shortest) way to approach this without re-writing the module in C#. I know there are a few CLR Lisp implementations but most seem unmaintained or incomplete and there are many things that cannot be trivially re-written in Scheme. Is there any facility that exposes the opposite of what RDNZL enables (.NET - Common Lisp)? Can I use RDNZL to deliver a DLL that accepts .NET objects?

• Could Grand Central Dispatch (`libdispatch`) ever be available on Windows?

  - by elliottcable

  I’m looking into multithreading, and GCD seems like a much better option than manually writing a solution using pthread.h and pthreads-win32. However, although it looks like libdispatch is either working on, or soon going to be working on, most newer POSIX-compatible systems… I have to ask, what about Windows? What are the chances of libdispatch being ported to Windows? What are the barriers preventing that from happening? If it came down to it, what would I need to do to preform that portage?

• How do you reach a "flow" state while programming?

  - by acrosman

  I'm not talking about program flow, but as in the state of working called flow, the state where you can get great work done the most effectively. I find that my current work environment while good in many ways does not allow me to get into a good state of mind for writing code most of the time (my job includes many other functions). If it's critical to get something done I'll often put on head-phones with classical music and try to drown out the office noise around me (and discourage co-workings from asking me questions). I am best able to get work done late in the evening when the house is quite and I've been thinking about the project for most of the day. What tricks have you found when working in less then perfect office environments?
