  • How to utilize network for p2p file sharing on Android Platform?

    - by CSharperWithJava
    I'm working on some apps for the android platform and I have two problems that I'm not quite sure how to approach, and both are closely related. How can I send a relatively small data file from one android device to another (preferably over the internet or directly through wireless network)? Is it possible to create a temporary p2p live data stream from one android device to another? An example application would be to stream low-res video from phone A's camera to phone B, or audio. I would much appreciate being pointed in the right direction on either issue (File transfer or real time data transfer).

  • Storing JSON in an msSQL database?

    - by JKirchartz
    I'm developing a form generator, and wondering if it would be bad mojo to store JSON in an SQL database? I want to keep my database & tables simple, so I was going to have `pKey, formTitle, formJSON` on a table, and then store {["firstName":{"required":"true","type":"text"},"lastName":{"required":"true","type":"text"}} in formJSON. would this slow down the DB server too much to set live? Any input is appreciated.

  • transforming binary data using ssis and sql server 2008

    - by Rick
    Hello All - I have a task to import/transform and extract zipped binary files that contain both text data as well as embeded binary data. Within the data is data that is relational in nature and needs to be processed into a defined database structure. Currently I have a C# single threaded app that essentially grabs all the files from the directory (currently there is 13K files of varying sizes) and extracts the data on a single thread line by line inserts to the database. As you could imagine this is a very slow process and unacceptable. There are several different parsing routines used depending on the header record in the file. There are potentially upto a million rows per file when all the data is extracted to the row level of detail. Follow on task is to parse those rows into their appropriate tables based on is content. i.e. the textual content has to be parsed further into "buckets" of like data in the database. That about sums up the big picture. Now for the problem task list. How do i iterate through a packet of data using SSIS? In the app the file is decompressed and then is parsed using streams data type and byte arrays and is routed to the required parsing routine based on the header data of each packet. There is bit swapping involved as well. Should i wrap up the app code into a script task(s) and let it do the custom processing? The data is seperated by year and the sql server tables is partitioned by year as well. I need to be able to "catch" bad file data as well and process by hand most likely. Should i simply load the zipped file to sql as a blob and parse the file with T-SQL? Would that be multi threaded if done that way? Not sure how to do the parsing in tsql that is involved here. Which do you think would be faster? Potentially the data that is currently processed via files could come to us via a socket. Can SSIS collect that data in real time? How would i go about setting that up? Processing these new files from the directorys will become a daily task. I can manage the data once i get it to sql server. Getting it there in a timely fashion seems to be the long pole in the tent for me. I would appreciate any comments or suggestions from the group. Rick

  • How to select records as columns in SQL

    - by Leigh
    Hi, I have two tables: tblSizes and tblColors. tblColors has columns called ColorName, ColorPrice and SizeID. There is one size to multiple colors. I need to write a query to select the size and all the colors (as columns) for a that size with the price of each size in its respective column. The colors must be returned as columns, for instance: SizeID : Width : Height : Red : Green : Blue 1---------220-----220----£15----£20-----£29 Hope this makes sense Thank you

  • Copy constructor with more than one parameter

    - by Ravi Gupta
    I am learning C++ and was reading copy constructor from the C++: The Complete Reference. The books says that It is permissible for a copy constructor to have additional parameters as long as they have default arguments defined for them. However, in all cases the first parameter must be a reference to the object doing the initializing. But I am confused that how we are going to pass those additional parameters? I am sure there should be some way which is not given in the book and which I am unable to figure out. Can anyone help me out? EDIT: Also is it possible to pass these extra parameters in all three cases i.e. ¦ When one object explicitly initializes another, such as in a declaration ¦ When a copy of an object is made to be passed to a function ¦ When a temporary object is generated (most commonly, as a return value)

  • Fast find near users using PostGIS

    - by opedge
    I have 5 tables: - users - information about user with current location_id (fk to geo_location_data) - geo_location_data - information about location, with PostGIS geography(POINT, 4326) column - user_friends - relationships between users. I want to find near friends for current user, but it takes a lot of time of executing select query to know if user is a friend and after that execute select using ST_DWithin.. May be something wrong in domain model or in queries?

  • Method hiding with interfaces

    - by fearofawhackplanet
    interface IFoo { int MyReadOnlyVar { get; } } class Foo : IFoo { int MyReadOnlyVar { get; set; } } public IFoo GetFoo() { return new Foo { MyReadOnlyVar = 1 }; } Is the above an acceptable way of implementing a readonly/immutable object? The immutability of IFoo can be broken with a temporary cast to Foo. In general (non-critical) cases, is hiding functionality through interfaces a common pattern? Or is it considered lazy coding? Or even an anti-pattern?

  • Protect files from svn commit.

    - by chrsk
    Hey, imagine a plain webapp with a log4j.properties which is under version control. I can't add it to svn:ignore because its a mandatory file. If i make custom changes for development and i don't want to commit them, i have to watch out for accidently commits. For one file it's easy to handle, with 3 or more files it becomes creepy. Is there a way to disable these files temporary from svn commit? So its easiert to commit? I'm working with svn and subclipse.

  • Relative links in CSS, after moving Wordpress

    - by bozdoz
    I created a blog with Wordpress on a temporary test domain. I put it in the main directory, not a folder. Now I want to move it to the correct website, in a folder. I can update all of the MySQL values for the site URL, and the relative path links work just fine. The problem is that I can't seem to make my CSS path links work. I realize that my problem is that they are relative to the CSS file, in the WordPress theme, and not the page. But how can I fix this? Here is an example: #topNav {background:#3a93c3 url(wp-content/uploads/2011/07/blueNav.jpg) repeat-x;} I have tried adding './', '../', and '../../' to the beginning, but it doesn't work at all. Any suggestions?
