  • How to store a numeric value which can have other statuses in a database?

    - by Jiho Han
    I need to store a set of numbers in a database which are imported from a spreadsheet. Sometimes a number is just a number. But in other times, a value can be "missing", "N/A", or blank and these all represent different things. What would be a good approach to store these numbers in the database? Originally I only had to account for N/A. So I made it -1 as I imported them (this only works if the number can never be negative obviously). I could use other negative numbers for other statuses. However, that seems clunky to me. Should I store the numbers as string then apply conversion at use time? Should I create a matching table that stores different statuses of each value?

  • How to kill an Android activity when leaving it so that it cannot be accessed from the back button?

    - by johnrock
    In an given Android activity, I would like to start a new activity for the user at some point. Once they leave the first activity and arrive at the second, the first activity is stale and I want to remove it completely so it can not be accessed again from the back button. How is the best way to accomplish this? How do I kill or destroy this activity immediately after the user has launched the new activity?

  • [C#] SQLite - Creating and changing databases on the fly

    - by Oskar Kjellin
    Today I use SQLite and send a database-file with the project. However I want the database to be created when the user first starts the software. Is there a way to copy the code needed to create a database based on the existing database? The problem is that when a user downloads a new version he might be tricked into copying over his last database and lose the data. I'd like a nice way to check the version of the database and modify it if I need new columns or tables etc. Or, if it does not exist at all, create a new database? I know I can probably make create the code to make the database from the beginning but I want it to be based on the existing database I have created by a gui.

  • debugging native code (C++) using gdb on android with Eclipse. Is it possible?

    - by noisy
    Hi, I have some piece of code which uses JNI. I can debug code wrote in Java directly in Eclipse (using ADT). I even have a script, which help me debug native code with gdb. However this is not very comfortable way for doing this. Is it possible to configure Eclipse to use gdb (I guess gdbserver) for debbuging android native applications? Do you know where I could find any description of this?

  • How can I create an email newsletter by taking objects from a database?

    - by jimmy
    Well, I'm trying to create a newsletter, that will send emails to users in a database. The newsletter itself would draw "events" and other activities from a database. Whats the best way to take that list, and put them in an email? I was thinking about putting them into an html page, then sending an html email, but not all emails support html(like school email). What would your guys recommend? Could you point me to some good resources? Also, this is for a school project, so I cant use any open source type stuff, unfortunately :(

  • How to rollback a database deployment without losing new data?

    - by devlife
    My company uses virtual machines for our web/app servers. This allows for very easy rollbacks of a deployment if something goes wrong. However, if an app server deployment also requires a database deployment and we have to rollback I'm kind of at a loss. How can you rollback database schema changes without losing data? The only thing that I can think of is to write a script that will drop/revert tables/columns back to their original state. Is this really the best way?

I'm using the HTC G1. I also did the "Turn on "USB Debugging" on your device" step... anyone got an idea??

    - by Jörgen

Now I'm at the point where I do alot of text info such as help texts, eula, privacy policy etc. I realized that I'm not sure what would the best way to store these texts. 1.

  • Can Android do peer-to-peer ad-hoc networking?

    - by Doughy
    Is it possible to set up Android in ad-hoc peer-to-peer wifi mode? For example, I would like to have one phone broadcast a message, and have all peers in the network receive the broadcast, without having a server. I would like to use wifi since bluetooth range is more limited.

  • How do you handle descriptive database table names and their effect on foreign key names?

    - by Carvell Fenton
    Hello, I am working on a database schema, and am trying to make some decisions about table names. I like at least somewhat descriptive names, but then when I use suggested foreign key naming conventions, the result seems to get ridiculous. Consider this example: Suppose I have table session_subject_mark_item_info And it has a foreign key that references sessionSubjectID in the session_subjects table. Now when I create the foreign key name based on fk_[referencing_table]__[referenced_table]_[field_name] I end up with this maddness: fk_session_subject_mark_item_info__session_subjects_sessionSubjectID Would this type of a foreign key name cause me problems down the road, or is it quite common to see this? Also, how do the more experienced database designers out there handle the conflict between descriptive naming for readability vs. the long names that result? I am using MySQL and MySQL Workbench if that makes any difference. Thanks!

  • Encrypt/Decrypt SQLite-database and use it "on the fly"

    - by Berschi
    Here's the thing: In my Qt4.6-Project, I use a SQLite-Database. This database shouldn't be unencrypted on my harddrive. So I want, that on every start of my program, the user gets asked to enter a password to decrypt the database. Of course the database never should appear "in clear" (not encrypted) on my harddrive. So is there any possibility to decrypt a SQLite-database "on the fly" and read and write data? What algorithm is here the best (maybe AES)? When it's not possible (or very slow), maybe it's better to encrypt every string in the database and decrypt the string when the password was right (so that a user could open the database, but has no clue what all the entrys could mean)?

  • Android - Run in background - Service vs. standard java class

    - by Chris
    In Android, if I want to do some background work, what is the difference between Creating a Service to do the work, and having the Activity start the Service VS. Creating a standard java class to do the work, and having the Activity create an object of the class and invoke methods, to do the work in separate threads Thanks Chris

  • How to schedule a cron job to backup a MySql database every week?

    - by KevinM
    What is a command line I can use to back up a MySql database every single week into a file name with the date (so that it doesn't collide with previous backups)? Also, is this a reasonable backup strategy? My database is relatively small (a complete export is only 3.2 megs right now). The churn rate is relatively low. I need to be able to get the complete DB back if something goes wrong. And it would be extra cool if there's a way that I could see the changes that occur across a time span.
