• How to store coordinates in a database

  - by Tim

  Hello all! I have a Flex GUI where I have to place quadrate elements. The position of these elements need to be stored into a database. So I can create two integer fields in the db table x and y. Also I need an angle, because the user can rotate these elements, so I can also make a int (int is okay, I do not need a double value therefore). As a ORM, I use Hibernate. But the question is, if creating three integer fields is the best way to handle this. Perhaps someone can tell me if this will be okay or if there are better ways? Thanks a lot in advance & Best Regards.

• .net c# datagridview populating with non database data/setup

  - by flavour404

  Hi, I have never used the datagridview in any other scenario other than one where it is populating by a database so suddenly my mind goes blank... I have 10 tubes, each with 8 vertical positions within it, so I have a 10 by 8 grid basically. Each has of those slots has (or not) an image in a folder. How do I get a datagridview to reflect this information, draw a grid, check the folder and if the image exists paint it white, and if not paint it red? Sorry it if sounds a little odd, thanks, R.

• Extract substructure from a text file using bash or python

  - by Werner

  Hi, I have a huge text file, which follows the structure: SET TAG1 ... ... SET ... SET TAG2 ... ... SET ... ... I would like to extract for a specific TAG, (i.e. TAG54) its individual "substructure", which would be SET TAG54 ... ... SET Each substructure, for a given TAG_i contains always: first line:SET second line:TAG_i (in this case TAG54) an arbitrary number of lines last line:SET I wonder what would be the best way to do this, whether in bash or python, so for a given TAG, one can "extract" this substructure. Thanks

• Create a PHP cache system in MySQL database?

  - by Zach Smith

  I'm creating a web service that often scrapes data from remote web pages. After scraping this data, I have a simple multidimensional array of information to use. The scraping process is fairly taxing on my server, and the page load takes a while. I was considering adding a simple cache system using a MySQL database, where I create one row per remote web page with a the array of information pulled from it stored as a JSON encoded string. Is this a good enough system? Or would something like a text file per web page be a better idea?

• Replacing Text in a Toggled Anchor with JQuery

  - by willmcneilly

  Hi I'm trying to change the text in an anchor on toggle. I'm doing this way at the moment but have found that once the anchor markup has replaced the toggle no longer works. Can someone please explain why this is happening and a solution? Many thanks. $('a#toggleHeader').toggle(function() { $('#header-wrapper').slideUp(); $(this).replaceWith('< href=\"#\" id="toggleHeader">Show Header</>'); //Note:I've move the anchor because I can only post one anchor as a new user },function(){ $('#header-wrapper').slideDown(); $(this).replaceWith('<a href=\"#\" id="toggleHeader">Hide Header</a>'); });

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• Spring security with database and multiple roles?

  - by Joe

  I'm trying to make an application using spring 3.0. Now I've decided to try my hand at spring-security and hibernate. I've already seen that it's possible to back it with a databasem and I've seen a reference to defining your own queries? Now the problem I have is that the tutorials I've been finding aren't too clear and that they assume that a user can only have one role. I want to give some users multiple roles. So I was thinking about a database scheme along the lines of: User: user_id username password registrationDate User_Role: user_id role_id Role: role_id rolename Now I was wondering if anyone had some pointers to some usefull tutorials/advice/comments.

• WebSQL Databases between two different pages?

  - by Srikanth Rayabhagi

  Is there any particular way in which we can access the Web SQL Database of one page, by other page. To make it more clear, suppose a.com creates the database DB and store some info. Now b.com comes and want to access the same database DB. Is there a way? Or are there any alternatives to do this? I tried to implement in HTML5 and Javascript but the databases as well as the localStorages are confining only to particular pages, I want this to be cross the pages.

• Python - read numbers from text file and put into list

  - by user1647372

  So like the title says im starting to learn some python and im having trouble picking up on this technique. What I need to accomplish is to read in some numbers and store them in a list. The text file looks like the following: 0 0 3 50 50 100 4 20 Basically these are coordinates and directions to be used for python's turtle to make shapes. I got that part down the only problem is getting them in a correct format. So what I can not figure out is how to get those numbers from the file into [ [0, 0, 3, 50], [50, 100, 4, 20] ] A list, with each four coordinates being a list in that one big list. Heres my attempt but it as I said I need some help - thank you. polyShape=[] infile = open(name,"r") num = int(infile.readline(2)) while num != "": polyShape.append(num) num = int(infile.readline(2)) infile.close()

• SQL Server 2008 database timeout after delete

  - by stephenbayer

  I'm running the following statement, it is working locally with SQL Server 2008, however, there is SQL Server 2008 Express on the development server, and after the sql statement runs, I am unable to do SELECT statements on the table in which I deleted the record. Both databases were created with the same table creation scripts. "DELETE FROM [dbo].[tblMiddayMover] WITH (ROWLOCK) WHERE [idMiddayMover] = @IdMiddayMover" What reasons would this statement ever cause the database to hang. After executing that statement, the following SELECT statement causes an error. "SELECT * FROM [dbo].[tblMiddayMover] WHERE [fldActive] = 1" I get the following error: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. I can do select statements on any other table with no issues.

• inputMismatchException Java reading doubles from plain text file

  - by user939287

  Using double variable = inputFile.nextDouble(); Gives the mismatch error and I can't figure out why... Anyone know what's up? The input file is just a bunch of doubles like 5.0... Okay here is the code snippet String fileName; Scanner scanner = new Scanner(System.in); System.out.println("\nEnter file name that contains the matrix and vector: "); fileName = scanner.nextLine(); Scanner inputFile = new Scanner(fileName); double a1 = inputFile.nextDouble(); the input file is a plain text document .txt in this format 5.0 4.0 -3.0 4.0 2.0 5.0 6.0 5.0 -2.0 -13.0 4.0 12.0 I don't understand why it wouldn't take those as doubles... As far as what its expecting the format of the file to be... I suppose binary? isn't that the default? I didn't specify in the code...

• Parsing C# Script into Java

  - by pantaryl

  I'm looking for a way to easily read in a C# file and place it into a Java Object for database storage (storing the class name, functions, variables, etc). I'm making a Hierarchical State Machine AI Building Tool for a game I'm creating and need to be able to import an existing C# file and store it in a database for retrieval in the future. Does anyone know of any preexisting libraries for parsing C# files? Something similar to JavaParser? Thanks everyone! EDIT: This needs to be part of my Java Project. I'll be loading in the C# files through my Java Application and saving it into my db4o database.

• PHP: Remove blank line before text

  - by Bailey

  Occasionally, my email-to-support-ticket system catches an extra line break before the message itself, thus my messages look like this: " Hello. I have been wondering if y..." What can I use to get rid of that line before the text? It is on random occasion due to email providers and the way they format their emails using mime. I have already tried the trim functions but no luck. (Yes, I also tried ltrim) Once processed it should look like: "Hello. I have been wondering if y..."

Also because of different number of elements in each element of the list it is not possible to use write() or write.table().

• The best way to store username and password without a database

  - by Mokuchan

  Hello everyone, I want to build a simple single user login "library" in PHP, but I'm facing the following dilemma: how should I store username and password if I'm not using a database? A simple plain text file could be easily read and then the password could be easily decripted so that's not an option. If I create a php file with just <?php $Username= "username"; $Password= "password"; ?> then no one should be able to read it and I could simply include this file where I need it, but I'm not really sure you can't find a better way to do this! So what's, in your opinion, the best solution to this problem (and why)? Thanks
