  • Database Error django

    - by Megan
    DatabaseError at /admin/delmarva/event/ no such column: delmarva_event.eventdate I created a class in my models.py file: from django.db import models from django.contrib.auth.models import User class Event(models.Model): eventname = models.CharField(max_length = 100) eventdate = models.DateField() eventtime = models.TimeField() address = models.CharField(max_length = 200) user = models.ForeignKey(User) def __unicode__(self): return self.eventname and now when i try to view my events in my admin or my main_page it gives me the error that there is no eventdate. I tried syncing the db again but nothing changed. Also, I hashtagged eventdate out to see if I get a different error and then it states that delmarva_event.eventtime does not exist as well. I It is weird because it does not have a problem with eventname. Any suggestions would be greatly appreciated!

  • How to edit doxygen.config from shell script?

    - by Sayan Ghosh
    Hi, I tried using Apple's shell script to automate doc set creation with every build (and loading that in XCode) - http://developer.apple.com/tools/creatingdocsetswithdoxygen.html but found that it had some bugs. Firstly it's not updating the entries in doxygen.config, perhaps one needs to put the settings in the exact hierarchy as it appears in the native doxygen file (?). My intention is to specify the settings in the following fashion in the shell script, and have a suitable config file generated tailored to my needs. ... echo "DOCSET_FEEDNAME = Some app" $TEMP_DIR/doxygen.config echo "GENERATE_LATEX = NO" $TEMP_DIR/doxygen.config echo "RECURSIVE = YES" $TEMP_DIR/doxygen.config ... Thank you, Sayan

    - by Synxmax
    Dear Guys I am somehow newbie and sometimes guru , but at this moment i don't have enough time to research My nightmare is , my boss ask me to create an interactive floor ( he just saw in an exhibition ) , he ask me to create one of them instead of buying , i am an actionscript crawler and developer with some skills in java and c# programming , i just made some track motion with a simple web cam , and this idea came to my mind if i can use an infrared or thermographic camera instead of simple camera so i can get better positioning if camera place at top of floor ! Now i just came here to ask you guys is there any resource , tip , help i can know before getting into this deal !? is there any lib or api out to deal with this ?! EVEN, if there is any resource , article from another language c++ , c , .... could help i just didn't have enough time to test lot of ways If you search interactive floors , or interactive floor projection you can find some companies who provide such a thing Thanks in advance ( and sorry for my damn poor english , français could be better :D )

  • How to create a glib.Source from Python?

    - by Matt Joiner
    I want to integrate some asyncore.dispatcher instances into GLib's default main context. I figure I can create a custom GSource that's able to detect event readiness on the various sockets in asyncore.socket_map. From C I believe this is done by creating the necessary GSourceFuncs which could involve cheap and non-blocking calls to select, and then handling them using asyncore.read, .write and friends. How do I actually create a GSource from Python? The class glib.Source is undocumented, and attempts to use the class interactively have been in vain. Is there some other method that allows me to handled socket events in the asyncore module without resorting to timeouts (or anything that endangers potential throughput and CPU usage)?

  • Weird exception with OLEDB Parameter Insert

    - by Seamus MacKenzie
    Getting a strange error when trying to insert data into an Access database using parameters. the line where I am getting a problem is :- thisCommand.CommandText = "INSERT INTO Events (Venue_ID, Date_Start, Date_End, Time_Start, Time_End, Name, Description, Event_Type, Buy_Tickets_URL) VALUES (@VenID, @DStart, @DEnd, @evTime, @evTime, @Name, @Des, @EvType, @SysUrl);"; string desc = GetDesc(rec.EvName); thisCommand.Parameters.AddWithValue("@Des", desc); thisCommand.ExecuteNonQuery(); None of the other parameters cause a problem but when trying to insert data to the description field I get a database exception saying the field is too small to accept the amount of data. The problem is my program is only trying to insert 3 characters when it throws the error and the Description field is a memo so should be able to hold up to 65000+ characters. When inserting a value manually in the CommandText everything works fine so it must be something to do with the parameter properties.

  • Storing SQL queries in Table in sql server

    - by Rohit
    We have multiple jobs in our system.These jobs are listed in a grid. We have 3 different user types (usertypeid 1,2,3). For each user listing is different and he can filter listing by selecting view from a dropdown. ViewName in the below table is the view which needs to be displayed. To achieve this functionality, a fellow developer has created the following table structure and stored sql fragments in SQLExpression in the below table. According to me the query should not be stored in database. What are the pros and cons of this approach and what are the available alternatives? JobListingViewID ViewName SQLExpression UserTypeID 3 All Jobs 1 = 1 3 4 Error Jobs JobStatusID IN ( 2 ) 1 5 Error Jobs JobStatusID IN ( 2 ) 2 6 Error Jobs JobStatusID IN ( 2 ) 3 7 Speech JobStatusID IN ( 1, 3, 8 ) 1

  • Exception is swallowed by finally

    - by fiction
    static int retIntExc() throws Exception{ int result = 1; try { result = 2; throw new IOException("Exception rised."); } catch (ArrayIndexOutOfBoundsException e) { System.out.println(e.getMessage()); result = 3; } finally { return result; } } A friend of mine is a .NET developer and currently migrating to Java and he ask me the following question about this source. In theory this must throw IOException("Exception rised.") and the whole method retIntExc() must throws Exception. But nothing happens, the method returns 2. I've not tested his example, but I think that this isn't the expected behavior. EDIT: Thanks for all answers. Some of you have ignored the fact that method is called retIntExc, which means that this is only some test/experimental example, showing problem in throwing/catching mechanics. I didn't need 'fix', I needed explanation why this happens.

  • Performance of Managed C++ Vs UnManaged/native C++

    - by bsobaid
    I am writing a very high performance application that handles and processes hundreds of events every millisecond. Is Unmanaged C++ faster than managed c++? and why? Managed C++ deals with CLR instead of OS and CLR takes care of memory management, which simplifies the code and is probably also more efficient than code written by "a programmer" in unmanaged C++? or there is some other reason? When using managed, how can one then avoid dynamic memory allocation, which causes a performance hit, if it is all transparent to the programmer and handled by CLR? So coming back to my question, Is managed C++ more efficient in terms of speed than unmanaged C++ and why?

  • SVNServ deny write access to a directory via wildcard match.

    - by Wes
    Hi, We have a requirement that every piece of code that makes it into production will be reviewed by a senior developer. The way I have envisioned this working is by a naming convention for branches that regular developers cannot check code into. Following the SVN recomended directory structure this translates into something like. [project-name]/trunk/ [project-name]/branches/ [project-name]/branches/development-01 [project-name]/branches/development-02 [project-name]/branches/task-increasefontsize [project-name]/branches/release-01 [project-name]/branches/release-02 [project-name]/tags/ So in the authz file I would like to have something like the following [/] @developers = rw [/*/branches/release-*] @developers = r @senior_developers = rw However I can't find any evidence that SVN supports * (or any other wildcard character). Is such a thing possible or do I need a pre-commit hook?

  • BULK SMS, Long Codes (VMN MSIDN), T-mobile?

    - by John
    Does any US wireless carrier offer individuals or companies with a direct connection to the SMSC? The number is 747-772-3101 (repalce 7's with 6's) This number is registered to t-mobile, also verified by t-mobile to be a valid subscriber sending 160,000+ text messages monthly and that all they have is an unlimited text messaging plan on top of the cheapest voice plan. This company of the number verified to me that they don't use gsm modems as they are too slow. So I know it's possible but who would I contact, Sales or anyone else reachable through a 1-800 is ignorant to these services and developer.t-mobile is worthless and doesn't reply to emails. Any info??

  • Is code clearness killing application performance?

    - by Jorge Córdoba
    As today's code is getting more complex by the minute, code needs to be designed to be maintainable - meaning easy to read, and easy to understand. That being said, I can't help but remember the programs that ran a couple of years ago such as Winamp or some games in which you needed a high performance program because your 486 100 Mhz wouldn't play mp3s with that beautiful mp3 player which consumed all of your CPU cycles. Now I run Media Player (or whatever), start playing an mp3 and it eats up a 25-30% of one of my four cores. Come on!! If a 486 can do it, how can the playback take up so much processor to do the same? I'm a developer myself, and I always used to advise: keep your code simple, don't prematurely optimize for performance. It seems that we've gone from "trying to get it to use the least amount of CPU as possible" to "if it doesn't take too much CPU is all right". So, do you think we are killing performance by ignoring optimizations?

  • Calling functions outside paths

    - by user1775718
    In mongojs, when you do: var birds = db.birds.find(searchTerm, callback); ...how do you pass arguments to the callback? I've tried bind, as in: birds = db.birds.find(searchTerm, app.get('getBirds').bind(res)); ...but to no avail. Just fyi I'm trying to pass the response object of the GET route so that the callback can render using res.send(results). The other option is to set app.set('res': res); and call app.get('res') from the callback - I'm not sure this is a good idea. It works, but it doesn't obey the events loop model too well - I think the request back to the app may be costly? Any help would be gratefully accepted. :)

  • How can I show the "Upload" tab in CKEditor?

    - by Hermet
    Hi guys, I've checked the CKEditor developer documentation and also some solved questions in here about this editor but couldn't find one which helped me. The thing is, I have set up CKEditor and when I get into the images dialog I can't see any "Upload" tab. I am trying to set up a custom file uploader, and according to the documentation is something like this: <script type="text/javascript"> CKEDITOR.replace( 'cuerpo', { filebrowserBrowseUrl : '/imgs/explorador.php', filebrowserUploadUrl : '/imgs/subirImagenes.php' }); </script> Thank you, and apologies for my English.

  • Deployment of SSRS 2012 From SSDT Fails - The specified report server URL could not be found

    - by Tony Covarrubias
    I have recently installed SQL Server 2012 Developer on my laptop. I created a simple SSRS report using AdventureWorks201. The report builds fine but will not deploy. I get the error "The specified report server URL http:/localhost/Reports_MSSQLSERVER2012 could not be found" I am able to browse to said URL without issue. I can even upload the report and run it just fine. I am using an administrator account in both cases (on the URL and within SSDT). Is there some reason why SSDT cannot see the URL I am specifying?

  • Isuue when uploading new version to app store

    - by user2978997
    Can I use new certificate and provisioning profile to upload new version? We have discovered one or more issues with your recent delivery for "EMTV News". To process your delivery, the following issues must be corrected: Invalid Provisioning Profile - The provisioning profile included in the bundle com.pointabout.C1E322F0 (Payload/EMTV.app) is invalid. (Missing code-signing certificate.) For more information, visit the iOS Developer Portal. Once these issues have been corrected, go to the Version Details page and click "Ready to Upload Binary." Continue through the submission process until the app status is "Waiting for Upload." You can then deliver the corrected binary. Regards, The App Store team Note: I am using new Certificate and provisioning profile but same bundle ID which is being used in old version of the app.

  • Git - Committing Machine Specific Configuration Files

    - by Gordon
    A common scenario when I develop is that the codebase will have several config files which require machine specific settings. These files will be checked into Git and other developers will always accidentally check them back in and break someone else's configuration. A simple solution to this would be to just not check them in to Git, or even to additionally add a .gitignore entry for them. However, I find that it is much more elegant to have some sensible defaults in the file which the developer can modify to suit his needs. Is there an elegant way to make Git play nicely with such files? I would like to be able to modify a machine-specific configuration file and then be able to run "git commit -a" without checking that file in.

  • Problems with overlapping ChildWindows in Silverlight

    - by Humanier
    Hello, I have a Silverlight application. At some point the app shows a ChildWindow with two datagrids and three buttons on it. One of the buttons is 'Reset To Defaults'. After it's pressed, the app shows another ChildWindow on top of the current one in order to ask confirmation. After the second ChildWindow is closed the first one starts to act funny. It's still changing highlighting of the elements on mouse events (mouseover on a grid element, click on a button). But clicking on the buttons doesn't fire my custom event handlers anymore. The only thing which is working on the ChildWindow is a small cross button created by the framework itself in the upper-right corner of the ChildWindow. I'd be grateful for any ideas on the cause of the problem or how to resolve it. Thanks.

  • Using CreateFileMapping between to programs - C

    - by Jamie Keeling
    Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

  • Migrating from CVS to Mercurial - how to handle cross-repo symbolic links?

    - by NVRAM
    I have a project that is stored in CVS as numerous modules/repositories. In several of the modules the CVS tree has symbolic links to the files in another tree. For example, the internal support tools have links to binary files (DLL, EXE) that are created and stored in the C# module. In all cases, the files are modified only in in the module where the files exist and are treated as read-only in the tree where the symbolic link exists. More often than not, the files are pulled to machines running MSWindows so the use of symbolic links on the developer machine is not an option. My question is this: Is there a mechanism in Mercurial that can provide the same capabilities?

  • android phone's scroll ball, D-Pad not working

    - by user270811
    hi, i have a Cliq and a MyTouch phone. i am writing a game that requires a fire button. on the cliq, it's the center of the D-Pad, and on the MyTouch, the scroll ball. i am handling the onKeyDown events via a separate thread. it all works until i press the button too many times, meaning the key down event is no longer fired off. if i press the D-Pad down or scroll the ball down, then the fire button works again. i can only guess that maybe the message queue within the OS is full, therefore the fire button temporarily malfuntions. can someone help me? thanks.

  • Qt on Mac: where to find "configure"

    - by Gil
    hi, I am very new to Mac. I downloaded QT SDK Mac Open source (http://get.qt.nokia.com/qtsdk/qt-sdk-mac-opensource-2010.02.dmg) and installed the Package. I can run qmake, build samples and run demos, but I cannot run configure (in order to build the Qt libraries statically). It says: -bash: No such file or directory. Documentation says I should run this in the "Qt root folder", but what is this folder in Mac? I looked for it in /usr/bin, /usr/local/Qt4.6, /Developer/Tools/Qt. Anyway, what is "configure" on Mac. is it an executable or a script? Thanks a lot

    I'm getting "could not find class" error when I run my app. Understand that copulation and execution path different but I followed the recommendations of another question to create a sub dir under my project of lib and put the jar there but still no luck. using Eclipse and it is when I run on a device from eclipse (unable to get the broadcast events I want to trigger this code from simulator, i.e. wifi and blue-tooth). Any way to look at the apk to see what's in it like this jar file? looking around did not see anything.

  • SharePoint SLK and T-SQL xp_cmdshell safety

    - by Mitchell Skurnik
    I am looking into a TSQL command called "xp_cmdshell" to use to monitor a change to a the SLK (SharePoint Learning Kit) database and then execute a batch or PowerShell script that will trigger some events that I need. (It is bad practice to modify SharePoint's database directly, so I will be using its API) I have been reading on various blogs and MSDN that there are some security concerns with this approach. The sites suggest that you limit security so the command can be executed by only a specific user role. What other tips/suggestions would you recommend with using "xp_cmdshell"? Or should I go about this another way and create a script or console application that constantly checks if a change has been made? I am running Server 2008 with SQL 2008.

  • Weird Behavior with Jquery image slideshow... Help!

    - by Thomas
    I built a jquery slideshow based on the tutorial found here: http://www.queness.com/post/152/simple-jquery-image-slide-show-with-semi-transparent-caption It seems to be working perfectly fine, except that it behaves strangley right at the beginning when it displays the first image. The first image appears like normal and then flashes, fades to white and disappears completely. After that, the first slide reappears and behaves normally, transitioning to the next image. The slideshow in question is center page on the right: http://www.loftist.com/ I am not a JS developer, so I am not sure how to troubleshoot this problem. Any help would be greatly appreciated, thanks!

  • Jquery binding event on selected class

    Is it achievable in jquery to bind an event to a group of control that has certain class? It seems to me, it can't. I google a bit and all that came up are nothing to do with events. Here's how my code looks - $('.numonly').bind('keypress',function(event){ if (event.which > 31 && (event.which < 48 || event.which > 57)) return false; });
