  • Is my method for avoiding dynamic_cast<> faster than dynamic_cast<> itself ?

    - by ereOn
    Hi, I was answering a question a few minutes ago and it raised to me another one: In one of my projects, I do some network message parsing. The messages are in the form of: [1 byte message type][2 bytes payload length][x bytes payload] The format and content of the payload are determined by the message type. I have a class hierarchy, based on a common class Message. To instanciate my messages, i have a static parsing method which gives back a Message* depending on the message type byte. Something like: Message* parse(const char* frame) { // This is sample code, in real life I obviously check that the buffer // is not NULL, and the size, and so on. switch(frame[0]) { case 0x01: return new FooMessage(); case 0x02: return new BarMessage(); } // Throw an exception here because the mesage type is unknown. } I sometimes need to access the methods of the subclasses. Since my network message handling must be fast, I decived to avoid dynamic_cast<> and I added a method to the base Message class that gives back the message type. Depending on this return value, I use a static_cast<> to the right child type instead. I did this mainly because I was told once that dynamic_cast<> was slow. However, I don't know exactly what it really does and how slow it is, thus, my method might be as just as slow (or slower) but far more complicated. What do you guys think of this design ? Is it common ? Is it really faster than using dynamic_cast<> ? Any detailed explanation of what happen under the hood when one use dynamic_cast<> is welcome !

  • how to create a dynamic sql statement w/ python and mysqldb

    - by Elias Bachaalany
    I have the following code: def sql_exec(self, sql_stmt, args = tuple()): """ Executes an SQL statement and returns a cursor. An SQL exception might be raised on error @return: SQL cursor object """ cursor = self.conn.cursor() if self.__debug_sql: try: print "sql_exec: " % (sql_stmt % args) except: print "sql_exec: " % sql_stmt cursor.execute(sql_stmt, args) return cursor def test(self, limit = 0): result = sql_exec(""" SELECT * FROM table """ + ("LIMIT %s" if limit else ""), (limit, )) while True: row = result.fetchone() if not row: break print row result.close() How can I nicely write test() so it works with or without 'limit' without having to write two queries?

  • [ASP.NET] IIS7 downloading file length

    - by GTD
    I've following code for file download: FileInfo fileInfo = new FileInfo(filePath); context.Response.Clear(); context.Response.ContentType = "application/octet-stream"; context.Response.AddHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(filePath)); context.Response.AddHeader("Content-Length", fileInfo.Length.ToString()); context.Response.WriteFile(filePath); context.Response.End(); When I run it on my local IIS6 it works fine. Web browser (tested on IE8, Firefox 3.5.2, Opera 10) shows file length before I start download the file. When I run this code on remote IIS7, web browser doesn't shows file length. File length is unknown. Why I don't get file length when this code runs under IIS7?

  • Drupal Views display newest content per taxonomy limit to one node

    - by digital
    Hi, I want to create a view where all 5 of my taxonomy terms are displayed and it then displays the latest node published but this is limited by 1. For Example: Tax Term 1 Latest node published Tax Term 2 Latest node published etc etc Currently I'm grouping by taxonomy term so it's displaying all nodes published then sorted by published date desc. I can't quite figure out how to limit the nodes to only show one item per taxonomy term. Any help would be greatly appreciated.

  • How to pass dynamic parameters to .pde file

    - by Kalpana
    class Shape contains two methods drawCircle() and drawTriangle(). Each function takes different set of arguments. At present, I invoke this by calling the pde file directly. How to pass these arguments from a HTML file directly if I have to control the arguments being passed to the draw function? 1) Example.html has (current version) <script src="processing-1.0.0.min.js"></script> <canvas data-processing-sources="example.pde"></canvas> 2) Example.pde has class Shape { void drawCircle(intx, int y, int radius) { ellipse(x, y, radius, radius); } void drawTriangle(int x1, int y1, int x2, int y2, int x3, int y3) { rect(x1, y1, x2, y2, x3, y3); } } Shape shape = new Shape(); shape.drawCircle(10, 40, 70); I am looking to do something like this in my HTML file, so that I can move all the functions into a separate file and call them with different arguments to draw different shapes (much similar to how you would do it in Java) A.html <script> Shape shape = new Shape(); shape.drawCircle(10, 10, 3); </script> B.html <script> Shape shape = new Shape(); shape.drawTriangle(30, 75, 58, 20, 86, 75); </script> 2) Iam using Example2.pde has void setup() { size(200,200); background(125); fill(255); } void rectangle(int x1, int y1, int x2, int y2) { rect(x1, y1, x2, y2); } My Example2.html has var processingInstance; processingInstance.rectangle(30, 20, 55, 55); but this is not working. How to pass these parameters dynamically from html.

  • parse content away from structure in a binary file

    - by Jeff Godfrey
    Using C#, I need to read a packed binary file created using FORTRAN. The file is stored in an "Unformatted Sequential" format as described here (about half-way down the page in the "Unformatted Sequential Files" section): http://www.tacc.utexas.edu/services/userguides/intel8/fc/f_ug1/pggfmsp.htm As you can see from the URL, the file is organized into "chunks" of 130 bytes or less and includes 2 length bytes (inserted by the FORTRAN compiler) surrounding each chunk. So, I need to find an efficient way to parse the actual file payload away from the compiler-inserted formatting. Once I've extracted the actual payload from the file, I'll then need to parse it up into its varying data types. That'll be the next exercise. My first thoughts are to slurp up the entire file into a byte array using File.ReadAllBytes. Then, just iterate through the bytes, skipping the formatting and transferring the actual data to a second byte array. In the end, that second byte array should contain the actual file contents minus all the formatting, which I'd then need to go back through to get what I need. As I'm fairly new to C#, I thought there might be a better, more accepted way of tackling this. Also, in case it's helpful, these files could be fairly large (say 30MB), though most will be much smaller...

  • MVC2 - Dynamic Field Layout

    - by Rob
    I'm new to MVC and ADO.net Entity Framework. Instead of having to create an edit/display for each entity, I'd like to have the controller base class generate the view and validation code based off metadata stored in a table - something along those lines. I would imagine something like this has already been done, or there are good reasons for not doing it. Any insight or suggestions are appreciated.

  • Dynamic paging using divs and Javascript

    - by jethomas
    I have a recordset loop that creates a table, and every 9 items it wraps a div around them so basically looks like: <div> <table>rs1, rs2 ----> rs9</table> </div> <div> <table>rs10, rs11 ----> rs18</table> </div> etc... Now, I want it so at first only the first div is showing and the others are hidden, but I have ASP loop that generates clickable links for the various divs (pages) and clicking on any given link will show that div and hide all the others. Here is the asp code I have so far: Dim i If totalPages > 1 Then Response.Write("<div id='navigation'>") For i=1 to totalPages Response.Write ("<a href='' onlick=''>"& i &"</a> | ") Next Response.Write("</div>") End If Now I just need to figure out the javascript...

  • dynamic behavior of factory class

    - by manu1001
    I have a factory class that serves out a bunch of properties. Now, the properties might come either from a database or from a properties file. This is what I've come up with. public class Factory { private static final INSTANCE = new Factory(source); private Factory(DbSource source) { // read from db, save properties } private Factory(FileSource source) { // read from file, save properties } // getInstance() and getProperties() here } What's a clean way of switching between these behaviors based on the environment. I want to avoid having to recompile the class each time.

  • Django - serving and managing permissions for static content

    - by kRON
    I have certain documents that I want to limit access to through Django to authorized users with permissions only. If I'm going to use Django as a proxy to serve static files in a view, what are the implications? I'm used to serving static files in Apache and configuring that my media is served without any handlers, but what happens if someone starts downloading 500mb through my Django proxy? Will my Django thread be locked for that user until he recieves the 500mb response?

    - by dythffvrb
    This is my code: $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions', 'redirect_uri' => 'http://mysite.com/', )); It works but if I remove redirect_uri it doesn't work anymore. $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions' )); According to Facebook domcumentation redirect_uri is optional. https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/ Im trying to redirect the users to the same url they were on before logging in. Update: This problem occurs when the url is mysite.com/post23 but when url is mysite.com/staticpage or mysite.com there are no problems Any workarounds? EDIT: It looks like a bug, it doesn't work with certain url in the same site I wil try and report it to Facebook.

  • [Alfresco] property qualified-name in method getContentReader

    - by Ar3s
    Hi there, I first apologize for my poor english level and maybe for the stupidity of my question ;) I am on an alfresco project to learn how it works. I have to browse programatically my content repository and gather datas all along. In order to do that I guessed I had to use a ContentReader (I get from my ContentService) but the method getReader wants a nodeRef and a propertyQualifiedName. I am ok with the nodeRef, I get what it's needed for. But the propertyQualifiedName puzzles me, I barely get what it is but I frankly don't get how it is used. Reading some alfresco forum threads I get more and more scared that I dont even get how a reader works, I somewhere saw that a reader can read only one node and only one time per instance. If anyone knows a bit about the Java API for Alfresco Content Repository use I am all hears ! Cheers all !

  • oracle plsql select pivot without dynamic sql to group by

    To whom it may respond to, We would like to use SELECT function with PIVOT option at a 11g r2 Oracle DBMS.
