  • What .net CMS with forum, eCommerce and multilanguage support would you reccomend

    - by rdimescu
    I am considering to use a cms for my website. As I am a .net developer, I think the best ideea would be to chose a .net cms tool, but I am not sure which one to pick. I've heard sitefinity from telerik is quite good but unfortunately is quite expensive, DNN it's a pain. Umbraco seems preety good, but it lacks the e-Commerce module. What about mojo portal, have you used it? Which one would you recommend?

  • Utilizing Windows Handles without a forum.

    - by Scott Chamberlain
    I have a program that needs to sit in the background and when a user connects to a RDP session it will do some stuff then launch a program. when the program is closed it will do some housekeeping and logoff the session. The current way I am doing it is like this I have the terminal server launch this application. I have it set as a windows forms application and my code is this public static void Main() { //Do some setup work Process proc = new Process(); //setup the process proc.Start(); proc.WaitForExit(); //Do some housecleaning NativeMethods.ExitWindowsEx(0, 0); } I really like this because there is no item in the taskbar and there is nothing showing up in alt-tab. However to do this I gave up access to functions like void WndProc(ref Message m) So Now I can't listen to windows messages (Like WTS_REMOTE_DISCONNECT or WTS_SESSION_LOGOFF) and do not have a handle to use for for bool WTSRegisterSessionNotification(IntPtr hWnd, int dwFlags); I would like my code to be more robust so it will do the housecleaning if the user logs off or disconnects from the session before he closes the program. Any reccomendations on how I can have my cake and eat it too?

  • Algorithm to determine thread "hotness"

    - by nickf
    I'm trying to come up with a way to determine how "hot" certain threads are in a forum. What criteria would you use and why? How would these come together to give a hotness score? The criteria I'm thinking of include: how many replies how long since the last reply average time between replies The problems this algorithm must solve: A thread which has 500 replies is clearly hot, unless the last reply was over a year ago. A thread with 500 replies that was replied to a second ago is clearly hot, unless it's taken 4 years to reach 500 replies. A thread with 15 replies in the last 4 minutes is really hot! Any ideas, thoughts or complete solutions out there?

  • convert.php does not run in a screen session

    - by Tobias
    I am trying to convert a big forum. At the moment I have to do this via ssh and start convert.php with "php5 -f convert.php -- $OPTIONS". But my internet connection is a bit buggy and so it is often killed. If i start the above working command in a screen session it does not work. Instead php gives me the HTML code of the "convert.php" back. head of the page: X-Powered-By: PHP/5.2.12 Set-Cookie: PHPSESSID=6bc4370b2d8d40ff8c3ab23672ff4135; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-type: text/html Does it has something to do with the Sessions? But why does it work on the same ssh-connection without screen?

  • Render a partial from a task in Symfony 1.4

    - by Cryo
    I'm trying to render a partial in a Symfony task and having no luck. I found docs in 1.1 that say to just call get_partial() but apparently that's no longer readily available in 1.4. I tried loading the helper manually with sfLoader::getHelpers('Partial'); but I get "Class sfLoader not found". Any help would be greatly appreciated. For reference what I'm trying to do is generate an HTML file called 'header.html' from my global header partial used in all of my layouts for inclusion in a third-party forum I'm integrating (Simple Machines/SMF).

  • Is it possible to hide some topics in phpBB forum?

    - by Martin
    I would like to be able to hide some of the topics in a phpBB-based forum temporarily from the users - perhaps with the exception of administrators and moderators. I am using the forum for my students and I have solutions of some problems from exams and tests there - posted either by me or by some of the students. I plan to use the same or very similar problems during the next academic year. So I don't want the students to see them, but I want to make the solutions visible again after the tests; so that I do not have to post solutions to same questions again. Is something like this possible? Is this a standard part of phpBB, or do I need to install some modification(s) for it?

  • IPTV World Forum : vingt décodeurs TV fondés sur Qt illustrent les différentes facettes du framework (déclaratif, Web, widgets)

    Aujourd'hui se tient l'un des plus grands événements sur la télévision, l'IPTV World Forum, où un total de vingt sociétés exposent leurs décodeurs basés sur Qt (STB, pour Set-Top Box). Qt y est mis à l'oeuvre à toutes les sauces : de plus en plus de fabricants prévoient d'utiliser Qt Quick pour préparer des interfaces innovantes ; d'un autre côté, les télécoms et opérateurs de télévision numériques préfèrent les interfaces HTML5 avec Qt WebKit (cela sans compter ceux qui utilisent les interfaces plus classiques en C++). Trois ans auparavant, les sociétés utilisant Qt étaient rares à ce forum ; aujourd'hui, il est dur d'en trouver ne l'utilisant pas. On va passer en revue quelques utilisateurs de Qt. htt...

  • How to retrieve row count of one-to-many relation while also including original entity?

    - by kaa
    Say I have two entities Foo and Bar where Foo has-many Bar's, class Foo { int ImportantNumber { get; set; } IEnumerable<Bar> Bars { get; set; } } class FooDTO { Foo Foo { get; set; } int BarCount { get; set; } } How can I efficiently sum up the number of Bars per Foo in a DTO using a single query, preferrably only with the Criteria interface. I have tried any number of ways to get the original entity out of a query with ´SetProjection´ but no luck. The current theory is to do something like SELECT Foo.*, BarCounts.counts FROM Foo LEFT JOIN ( SELECT fooId, COUNT(*) as counts FROM Bar GROUP BY fooId ) AS BarCounts ON Foo.id=BarCounts.fooId but with Criterias, and I just can't seem to figure out how.

  • Help! cant login to my forum after .htaccess changes

    - by MrRioku
    I'm running a phpbb forum and I installed an SEO friendly URL Mod. After I installed it I wasn't able to login as the admin nor any other users... Well I've been messing around with this problem for a bit and I did find out that it was the .htaccess file that was causing me not to be able to login. I found out if I comment the canonical part out in the .htaccess file, my website allows me to login and see the working mod just fine but I get "http://phone7forum.com/" instead of what I want which is "http://www.phone7forum.com/ : enter code here # HERE IS A GOOD PLACE TO FORCE CANONICAL DOMAIN # RewriteCond %{HTTP_HOST} !^www\.phone7forum\.com$ [NC] # RewriteRule ^(.*)$ http://www.phone7forum.com/$1 [QSA,L,R=301] enter code here I definitely want the "http://www." since its the best method and holds the best weight.. But when I un-comment it, it will not allow me to login as the admin nor any user... Is there anything I can do to fix this matter??? I'd like to add, before I found this website I installed the Mod "Canonical URL" found here: http://www.phpbb.com/customise/db/mod/canonical_url/ Possibly this might be part of my issue? Maybe I should go undo everything that Mod told me to do and then try un-commenting the canonical section in the .htaccess file? Here is my complete .htaccess file as of now that produces the "http://phone7forum.com/" and allows me to login: [code] # Lines That should already be in your .htacess <Files "config.php"> Order Allow,Deny Deny from All </Files> <Files "common.php"> Order Allow,Deny Deny from All </Files> # You may need to un-comment the following lines # Options +FollowSymlinks # To make sure that rewritten dir or file (/|.html) will not load dir.php in case it exist # Options -MultiViews # REMEBER YOU ONLY NEED TO STARD MOD REWRITE ONCE RewriteEngine On # Uncomment the statement below if you want to make use of # HTTP authentication and it does not already work. # This could be required if you are for example using PHP via Apache CGI. # RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L] # REWRITE BASE RewriteBase / # HERE IS A GOOD PLACE TO FORCE CANONICAL DOMAIN # RewriteCond %{HTTP_HOST} !^www\.phone7forum\.com$ [NC] # RewriteRule ^(.*)$ http://www.phone7forum.com/$1 [QSA,L,R=301] # DO NOT GO FURTHER IF THE REQUESTED FILE / DIR DOES EXISTS RewriteCond %{REQUEST_FILENAME} -f RewriteCond %{REQUEST_FILENAME} -d RewriteRule . - [L] ##################################################### # PHPBB SEO REWRITE RULES ALL MODES ##################################################### # AUTHOR : dcz www.phpbb-seo.com # STARTED : 01/2006 ################################# # FORUMS PAGES ############### # FORUM INDEX REWRITERULE WOULD STAND HERE IF USED.

  • How can I convert a projection that's not part of spatial_ref_sys?

    - by Summer
    Hi, I'm importing shapefiles into a Postgres+PostGIS database. Here's my usual procedure: * Find an srid in the spatial_ref_sys table where srtext appears to match the shapefile's .prj file * Upload the data into a new table using the shp2pgsql utility, specifying the srid using the -s flag * Add the new table to my main geometry table, and on the way convert to an srid of 4269 (the Census standard projection) using ST_Transform Unfortunately, the spatial_ref_sys table doesn't include Mississippi state's standard projection. The contents of their .prj file is as follows, where I've bolded the parts I usually try to match: PROJCS["mstm",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",500000.0],PARAMETER["False_Northing",1300000.0],PARAMETER["Central_Meridian",-89.75],PARAMETER["Scale_Factor",0.9998335],PARAMETER["Latitude_Of_Origin",32.5],UNIT["Meter",1.0]] I eventually found the ogr2ogr utility, and especially with the "peace and joy" promises, I decided to give it a try. I tried this command: ogr2ogr -update -f "PostgreSQL" PG:"Connection details" "File name.shp" -t_srs EPSG:4269 -nln Table_Name I am now getting the error "Terminating translation prematurely after failed translation of layer" -- which seems to indicate that ogr2ogr is not going to be the savior I imagined in getting arbitrary .prj files neatly into the 4269 projection. Any ideas about what to do?

  • correct fisheye distortion

    - by Will
    I have some points that describe positions in a picture taken with a fisheye lens. I've found this description of how to generate a fisheye effect, but not how to reverse it. How do you calculate the radial distance from the centre to go from fisheye to rectilinear? My function stub looks like this: Point correct_fisheye(const Point& p,const Size& img) { // to polar const Point centre = {img.width/2,img.height/2}; const Point rel = {p.x-centre.x,p.y-centre.y}; const double theta = atan2(rel.y,rel.x); double R = sqrt((rel.x*rel.x)+(rel.y*rel.y)); // fisheye undistortion in here please //... change R ... // back to rectangular const Point ret = Point(centre.x+R*cos(theta),centre.y+R*sin(theta)); fprintf(stderr,"(%d,%d) in (%d,%d) = %f,%f = (%d,%d)\n",p.x,p.y,img.width,img.height,theta,R,ret.x,ret.y); return ret; }

Any suggestions? Thanks. -- Brian

Is there a straightforward way to do it in OpenCV, and does it perform well enough to do it to a live video feed?

  • Java multiple class compositing and boiler plate reduction

    - by h2g2java
    We all know why Java does/should not have multiple inheritance. So this is not questioning about what has already been debated till-cows-come-home. This discusses what we would do when we wish to create a class that has the characteristics of two or more other classes. Probably, most of us would do this to "inherit" from three classes. For simplicity, I left out the constructor.: class Car extends Vehicle { final public Transport transport; final public Machine machine; } So that, Car class directly inherits methods and objects of Vehicle class, but would have to refer to transport and machine explicitly to refer to objects instantiated in Transport and Machine. Car car = new Car(); car.drive(); // from Vehicle car.transport.isAmphibious(); // from Transport car.machine.getCO2Footprint(); // from Machine I thought this was a good idea until when I encounter frameworks that require setter and getter methods. For example, the XML <Car amphibious='false' footPrint='1000' model='Fordstatic999'/> would look for the methods setAmphibious(..), setFootPrint(..) and setModel(..). Therefore, I have to project the methods from Transport and Machine classes class Car extends Vehicle { final public Transport transport; final public Machine machine; public void setAmphibious(boolean b){ this.transport.setAmphibious(b); } public void setFootPrint(String fp){ this.machine.setFootPrint(fp); } } This is OK, if there were just a few characteristics. Right now, I am trying to adapt all of SmartGWT into GWT UIBinder, especially those classes that are not a GWT widget. There are lots of characteristics to project. Wouldn't it be nice if there exists some form of annotation framework that is like this: class Car extends Vehicle @projects {Transport @projects{Machine @projects Guzzler}} { /* No need to explicitly instantiate Transport, Machine or Guzzler */ .... } Where, in case of common names of characteristics exist, the characteristics of Machine would take precedence Guzzler's, and Transport's would have precedence over Machine's, and Vehicle's would have precedence over Transport's. The annotation framework would then instantiate Transport, Machine and Guzzler as hidden members of Car and expand to break-out the protected/public characteristics, in the precedence dictated by the @project annotation sequence, into actual source code or into byte-code. Preferably into byte-code. So that the setFootPrint method is found in both Machine and Guzzler, only that of Machine's would be projected. Questions: Don't you think this is a good idea to have such a framework? Does such a framework already exist? Tell me where/what. Is there an eclipse plugin that does it? Is there a proposal or plan anywhere that you know about such an annotation framework? It would be wonderful too, if the annotation/plugin framework lets me specify that boolean, int, or whatever else needs to be converted from String and does the conversion/parsing for me too. Please advise, somebody. I hope wording of my question was clear enough. Thx. Edited: To avoid OO enthusiasts jumping to conclusion, I have renamed the title of this question.
