  • HTML5 video element non-seekable when using Django development server

    - by Ory Band
    Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

  • .NET Framework - When to Upgrade?

    - by Andrew
    I’m faced with a challenge of leading two (currently) separate .NET development groups with different development strategies. One group is developing on the .NET Framework 2.0 (with maybe a few applications on 3.5). The other group immediately adopts any new framework that comes out, and begins coding any new applications with it (they are running 2.0-4.0 applications). For this last group, applications written in an earlier version than the latest framework do not get upgraded. What is the current school of thought when it comes to a company developing web applications on when to adopt a new framework, and whether to migrate applications built on previous versions to the latest framework or not? Years ago the thought was to wait until the technology became mainstream - but that doesn't seem to apply much now with .NET.

  • NHibernate SchemaUpdate adding existing foreign keys again?

    - by afsharm
    I'm using SchemaUpdate to synchronize my hbms with existing database. Database has recently created based on hbms and is completely up-to-date. But SchemaUpdate generates all foreign key constraints again. For example suppose you have Student and Teacher. Student has association to Teacher with name ArtTeacher. ArtTeacher is a foreign key from Student to Teacher. Suppose database is up-to-date and currently holde Student, Teacher and their foreign key relation. So HBM and Database are equivalent. Know SchemaUpdate must not do anything but when I see its generated scripts, it re-produce that foreign key again. Why this happens? Is there any way to avoid it?

  • Looking for a good course/book/resource on modern databases

    - by spanky
    This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.

  • Planning a programming project by example (C# or C++)

    - by Lunan
    I am in the last year of undergraduate degree and i am stumped by the lack of example in c++ and c# large project in my university. All the mini project and assignment are based on text based database, which is so inefficient, and console display and command, which is frustrating. I want to develop a complete prototype of corporate software which deals in Inventory, Sales, Marketing, etc. Everything you would usually find in SAP. I am grateful if any of you could direct me to a books or article or sample program. Some of the question are : How to plan for this kind of programming? should i use the concept of 1 object(such as inventory) have its own process and program and have an integrator sit for all the program, or should i integrate it in 1 big program? How to build and address a database? i have little bit knowledge in database and i know SQL but i never address database in a program before. Database are table, and how do you suppose to represent a table in a OOP way? For development type, which is better PHP and C++ or C# and ASP.NET? I am planning to use Web Interface to set form and information, but using a background program to handle the compute. .NET is very much integrated and coding should be much faster, but i really wonder about performance if compared to PHP and C++ package thank you for the info

  • Getting my app to work on my phone

    - by user237259
    Hello I wrote an app android sdk version 1.5 using it's built in emulator in eclipse. I created a database outside of eclipse populated it with data and push it to the emulator folder data/data/project name/database and could access it fine from the my app, everything was working great. My final step was to test the apk file on an actual phone. When I did that the program would not work. After looking into it I found that the database file was not being uploaded into the phone. Is there a special way to install the apk file on the actual phone to get the embedded database to work? Or can I assume that since everything worked fine on the sdk 1.5 emulator that everything will work when I upload it to the market. Thanks in advance.

  • SQL Drop Index on different Database

    - by Jim
    While trying to optimize SQL scripts, I was recommended to add indexes. What is the easiest way to specify what Database the index should be on? IF EXISTS (SELECT * FROM sysindexes WHERE NAME = 'idx_TableA') DROP INDEX TableA.idx_TableA IF EXISTS (SELECT * FROM sysindexes WHERE NAME = 'idx_TableB') DROP INDEX TableB.idx_TableB In the code aboce, TableA is in DB-A, and TableB is in DB-B. I get the following error when I change DROP INDEX TableA.idx_TableA to DROP INDEX DB-A.dbo.TableA.idx_TableA Msg 166, Level 15, State 1, Line 2 'DROP INDEX' does not allow specifying the database name as a prefix to the object name. Any thoughts are appreciated.

  • J2ME development and native API

    - by Attilah
    Is it possible to write a mobile application with J2ME and whenever we want to implement a functionality not offered by J2ME call native mobile API ? (kind of like what is done with .NET, whenever you need something not provided, you just call the Win32 API from the .NET platform).

  • MVC for web development: Sign-up form?

    - by incrediman
    How would I go about implementing a signup form using the MVC pattern for a website (I'm using PHP)? I think the controller should receive the POST data initially. Then probably some interation with the model might need to take place (if the user successfully signs up). Then I think the signup form view would be called, and a value would be passed in saying whether or not the signup was successful. Stuff I need help with: Where do I do input validation (ie. proper email address formatting)? How do I check to make sure the username is unique? Is the rest of my description alright? How would you go about doing an MVC website signup form?

  • minimum required bandwidth for remote database server

    - by user66734
    I want to build a small warehousing application for my company. We have a central warehouse which distributes to 8 sales points across the country. They insist on an in-house solution. I am thinking to setup a central mySQL db Linux server and have the branches connect to it to store sales. Queries to the db from the branches will be minimum, maybe 10 per hour. However I need all the branches to be able to store each sale data ( product ID, customer ID ) in the central db at peak time at most once every five minutes. My question is can I get away with simple 24mbps/768kbps DSL lines? If not what is the bandwith requirement? Can I rely on a load balancing router to combine additional lines if needed? Can you propose some server hardware specs?

  • decentralized development using git and git-svn

    - by CantGetANick
    We have 2-3 small teams of 2-3 people. We all use git for local and svn for central repository and git-svn got sync. This is works all the time except when we want to share our code between the team it self. So we have tried out git pull, this creates lots of conflicts and it does not detect that we are on the same tree. It fetches all the changes (same as clone then pull) Of course i dont want to clone full repo. every time I want to share. Please suggest a better flow. We can't get rid of central svn. We can't clone every time.

  • Windows service thread not updating database until complete

    - by dfarney
    I have a windows service with a FileSystemWatcher. When a new file is dropped in my folder a new thread is created, started, and I begin processing the file. Throughout this process I am making updates to the database (Linq to SQL) to keep track of the file's processing progress. Problem is none of my database updates are reflected throughout the process, just an update after everything has been completed. Any ideas? Note: when doing dev/testing my code was in an aspx page and worked great, but when I put it in a windows service I no longer get the progress updates. Thanks!

  • Using App Engine to update a database in a app

    - by tyczj
    I have been reading about app engine but I still dont know what I can and cant do with it in a android application. Basically what I want to do is be able to create/manage a database in the cloud that the app can pull down and update the local database if needed. Creation and managing would be done outside of the app by me. I dont know much about all of this as I am just getting started with it but I already have an application made, I just want to add this feature to it. I have never written any sort of Web Service calls or anything either but I have used them to get data and such Can this be done? Any tutorials out there to help me out?

  • Storing PDFs in MS Access Database using Forms

    - by Matthew Jones
    I need to store PDF files in an Access database on a shared drive using a form. I figured out how to do this in tables (using the OLE Object field, then just drag-and-drop) but I would like to do this on a Form that has a Save button. Clicking the save button would store the file (not just a link) in the database. Any ideas on how to do this? EDIT: I am using Access 2003, and the DB will be stored on a share drive, so I'm not sure linking to the files will solve the problem.

  • Unable to use getInt() but able to use getString() for a sqlite database

    - by mwrazam
    I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more
