• Get C# Templates For VS 2008 Shell

  - by Onorio Catenacci

  I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).

• open source project requirements

  - by skidding

  I know it's a very common question, but I don't see a previous one to be asked, since I'm interested in the basic steps, nothing in particular. It's the first time I want to license one of my projects, and it turns out, I don't know much about it. Let's say I want to use the MIT License. Do I just take the definition and paste it into my files? Does it need to be in ALL the files, or just one? or? I don't want any fancy rights so MIT has been recommended to me, do you suggest something else? I'm looking for impartial opinions. Thanks. What other aspects must I take into account? It's PHP, btw.

• How to make a thread try to reconnect to the Database x times using JDBCTemplate

  - by gillJ

  Hi, I have a single thread trying to connect to a database using JDBCTemplate as follows: JDBCTemplate jdbcTemplate = new JdbcTemplate(dataSource); try{ jdbcTemplate.execute(new CallableStatementCreator() { @Override public CallableStatement createCallableStatement(Connection con) throws SQLException { return con.prepareCall(query); } }, new CallableStatementCallback() { @Override public Object doInCallableStatement(CallableStatement cs) throws SQLException { cs.setString(1, subscriberID); cs.execute(); return null; } }); } catch (DataAccessException dae) { throw new CougarFrameworkException( "Problem removing subscriber from events queue: " + subscriberID, dae); } I want to make sure that if the above code throws DataAccessException or SQLException, the thread waits a few seconds and tries to re-connect, say 5 more times and then gives up. How can I achieve this? Also, if during execution the database goes down and comes up again, how can i ensure that my program recovers from this and continues running instead of throwing an exception and exiting?

• (Visual) C++ project dependency analysis

  - by polyglot

  I have a few large projects I am working on in my new place of work, which have a complicated set of statically linked library dependencies between them. The libs number around 40-50 and it's really hard to determine what the structure was initially meant to be, there isn't clear documentation on the full dependency map. What tools would anyone recommend to extract such data? Presumably, in the simplest manner, if did the following: define the set of paths which correspond to library units set all .cpp/.h files within those to belong to those compilation units capture the 1st order #include dependency tree One would have enough information to compose a map - refactor - and recompose the map, until one has created some order. I note that http://www.ndepend.com have something nice but that's exclusively .NET unfortunately. I read something about Doxygen being able accomplish some static dependency analysis with configuration; has anyone ever pressed it into service to accomplish such a task?

• Creating a project, from Makefile to static/dynamic libraries in UNIX

  - by Sasha

  Guys, would you describe a few things about c++ building blocks, on unix. I want to create an application that links against static libs and dynamic libs (.so). Question 1: How do I create static library using gcc/g++ ?How do I make my app link against it. Question 2: How to specify it in the makefile, linking against static and dynamic libs, assuming that both libraries have header files Summary: I have been using makefiles and libraries for years, written by someone else. Thus every time I modified it, I simply cut-and-pasted things around, without really understanding it. Now I want to get down to the ground and understand the building/linking/Creating Makfile process in-depth. What is a good book describing these concepts in intimate details? Thanks

• How to explain to a client that you've gone over-budget and you'll need more money/time to deliver w

  - by General Tapioca

  My situation is that I have agreed on a per-project proposal with the client. The proposal is vague, but still names functionality in a way that can be argued as to whether it's included or not, while leaving some room for interpretation. I originally pressed as much as I could to get a per-month contract, arguing that the project is mostly non-predictable, but the client refused. Being a small company, I had to fold and signed a contract on an estimate based on my group's estimations. At this point we have reached completion on about 85% of the features (we think) but we ran out of budget. We have been working for almost two years with this client in previous contracts, and we have delivered a good product that they are happy with, so we have a good standing relationship. More info: -There has been a bit of scope-creep, but I don't think enough for me to hide behind that argument -We've been delivering partial releases about monthly. -We don't have systematic user-testing in place.

• MonoTouch & SQLite - Cannot open database after previous successful connections

  - by Tanis Draven

  I am having difficulty in reading data from my SQLite database from MonoTouch. I can read and write without any difficulty for the first few screens and then suddenly I am unable to create any further connections with the error: Mono.Data.Sqlite.SqliteException: Unable to open the database file at Mono.Data.Sqlite.SQLite3.Open (System.String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool) [0x0007e] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLite3.cs:136 at Mono.Data.Sqlite.SqliteConnection.Open () [0x002aa] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLiteConnection.cs:888 I ensure that i dispose and close every connection each time i use it but still i have this problem. For example: var mySqlConn = new SqliteConnection(GlobalVars.connectionString); mySqlConn.Open(); SqliteCommand mySqlCommand = new SqliteCommand(SQL, mySqlConn); mySqlCommand.ExecuteNonQuery(); mySqlConn.Close(); mySqlCommand.Dispose(); mySqlConn.Dispose(); I'm guessing that I'm not closing the connections correctly. Any help would be greatly appreciated.

• NoSQL vs. MySQL when scalability is irrelevant

  - by Bryan Ward

  Recently I have read a lot about different NoSQL databases and how they are being effectively deployed by some major websites out there. I'm starting a project in which I think the schema-free nature of a database such as MongoDB would be tremendously useful. Everything I have read though seems to indicate that the main advantage of a NoSQL database is scalability. Is choosing a NoSQL database for the schema-free design just as legitimate a design decision as that of scalability?

• Best practice to structure large html-based project

  - by AntonAL

  I develop Rails based website, enjoying using partials for some common "components" Recently, i faced a problem, that states with CSS interference. Styles for one component (described in css) override styles for another components. For example, one component has ... <ul class="items"> ... and another component has it too. But that ul's has different meaning in these two components. On the other hand, i want to "inherit" some styles for one component from another. For example: Let, we have one component, called "post" <div class="post"> <!-- post's stuff --> <ul class="items"> ... </ul> </div And another component, called "new-post": <div class="new-post"> <!-- post's stuff --> <ul class="items"> ... </ul> <!-- new-post's stuff --> <div class="tools">...</div> </div Post and new-post have something similar ("post's stuff") and i want to make CSS rules to handle both "post" and "new-post" New post has "subcomponents", for example - editing tools, that has also: <ul class="items"> This is where CSS rules starting to interfer - some rules, targeted for ul.items (in post and new-post) applies subcomponent of new-post, called "tools" On the one hand - i want to inherit some styles On the other hand, i want to get better incapsulation What are the best practices, to avoid such kind of problems ?

• determine if a restaurant is open now (like yelp does) using database, php, js

  - by vee

  i was wondering if anyone knows how yelp determines what restaurants are "open now"? i'm developing a similar application using html/javascript/php. i was going to have a column in my database for each day, with comma separated hours written in "2243" format (10:43 pm). so for example if a restaurant is open for lunch and dinner it might be "1100,1400,1700,2200". then i'd check (using js) if the current time falls in one of the ranges for the current day. i'd also like to be able to determine if a restaurant is "open tonight", "open late", etc. for those i guess i'd check whether the open range overlaps with certain ranges. is there a better way to do this? particularly, how to store the hours in the database and then determine if they overlap with a given set of hours. thanks.

• Advice/suggestions for my first project PHP Classes

  - by Philip

  Hi guys, Any advice is welcome! I have a very limited understanding of php classes but below is my starting point for the route I would like to take. The code is a reflection of what I see in my head and how I would like to go about business. Does my code even look ok, or am I way off base? What are your thoughts, how would you go about achieving such a task as form-validate-insertquery-sendmail-return messages and errors? Please try and keep your answers simple enough for me to digest as for me its about understanding whats going on and not just a copy/paste job. Kindest regards, Phil. Note: This is a base structure only, no complete code added. <?php //======================================= //class.logging.php //======================================== class logging { public $data = array(); public $errors = array(); function __construct() { array_pop($_POST); $this->data =($this->_logging)? is_isset(filterStr($_POST) : ''; foreach($this->data as $key=> $value) { $this->data[$key] = $value; } //print_r($this->data); de-bugging } public function is_isset($str) { if(isset($str)) ? true: false; } public function filterStr($str) { return preg_match(do somthing, $str); } public function validate_post() { try { if(!is_numeric($data['cardID'])) ? throw new Exception('CardID must be numeric!') : continue; } catch (Exception $e) { return $errors = $e->getCode(); } } public function showErrors() { foreach($errors as $error => $err) { print('<div class="notok"></div><br />'); } } public function insertQ() { $query = ""; } } //======================================= //Usercp.php //======================================== if(isset($_GET['mode'])) { $mode = $_GET['mode']; } else { $mode = 'usercp'; } switch($mode) { case 'usercp': echo 'Welcome to the User Control Panel'; break; case 'logging': require_once 'class.logging.php'; $logger = new logging(); if(isset($_POST['submit']) { if($logger->validate_post === true) { $logger->insertQ(); require_once '/scripts/PHPMailer/class.phpmailer.php'; $mailer = new PHPMailer(); $mailer->PHPMailer(); } else { echo ''.$logger->showErrors.''; } } else { echo ' <form action="'.$_SERVER['PHP_SELF'].'?mode=logging" method="post"> </form> '; } break; case 'user_logout': // do somthing break; case 'user_settings': // do somthing break; ?>

• Looking for solution to persist rows sequence in a database table that allow efficient reordering at

  - by Chau Chee Yang

  I have a database table. There is a field name "Sequence" that indicate sequence when user presents the rows in report or grid visually. When the rows are retrieved and presented in a grid, there are few UI gadget that allow user to reorder the rows arbitrary. The new sequence will be persist in database table when user commit the changes. Here are some UI operations: Move to first Move to last Move up 1 row Move down 1 row multi-select rows and move up or down multi-select rows and drag to new position For operation like "Move to first" or "Move to Last", it usually involve many rows and the sequence those rows would need to be updated accordingly. This may not be efficient enough at runtime. It is a common practice to use INTEGER as sequence's data type. Other solution is using "DOUBLE" or "FLOAT" that could overcome the mass update of row sequence but we will face problem if we reach the limit of precision.
