  • How to save file and read

    - by Jessy
    Hello everyone, I create a program that place random image in grid layout format. The size of the grid layout is 6 x 6 = 36. Only 10 were filled with images (each image was different) and the rest were empty. freeimagehosting.net/uploads/bfb7e85f63.jpg How can I save it to a file and read it again, so it will display the same images with same placement on the grid? Here is the code that I used to save the images: //image file String []arrPic = {"pic1.jpg","pic2.jpg","pic3.jpg","pic4.jpg","pic5.jpg","pic6.jpg","pic7.jpg","pic8.jpg","pic9.jpg","pic10.jpg",,"pic11.jpg","pic12.jpg","pic13.jpg"}; ArrayList<String> pictures = new ArrayList<String>(Arrays.asList(arrPic)); ArrayList<String> file = new ArrayList<String>(); JPanel pDraw = new JPanel(new GridLayout(6,6,2,2)); ... //fill all grids with empty label for (int i =0; i<(6*6); i++){ JLabel lbl = new JLabel(""); pDraw.add(lbl); } ... //Choose random box to be filled with images for(int i=0; i<10; i++){ Boolean number = true; while(number){ int n = rand.nextInt(35); if(!(arraylist.contains(n))) number = false; arraylist.add(n); } //fill the grids with images for(int i=0; i<arraylist.size(); i++){ //select random image from arraylist int index = rand.nextInt (pictures.size()); String fileName = (String) pictures.get(index ); //find the image file icon = createImageIcon(fileName); //save the file in a new file file.add(fileName); //rescaled the image int x = rand.nextInt(50)+50; int y = rand.nextInt(50)+50; Image image = icon.getImage().getScaledInstance(x,y,Image.SCALE_SMOOTH); icon.setImage(image); //remove empty label and replace it with an image int one = (Integer) arraylist.get(i); pDraw.remove(one); final JLabel label; pDraw.add(label,one); }

  • Finding a small image in a bigger one

    - by tur1ng
    Given an image with a large dimension ( 1.000 x 1.000). What is a good approach to find a small image (e.g. 50 x 50) in the big one? The smaller image can be rotated and differ in the size, but only with a 1:1 ratio. It's not related to any programming language - I'm just interested in pattern recognition. Thank you.

  • EF4: ObjectContext inconsistent when inserting into a view with triggers

    - by user613567
    I get an Invalid Operation Exception when inserting records in a View that uses “Instead of” triggers in SQL Server with ADO.NET Entity Framework 4. The error message says: {"The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: The key-value pairs that define an EntityKey cannot be null or empty. Parameter name: record"} @ at System.Data.Objects.ObjectContext.SaveChanges(SaveOptions options) at System.Data.Objects.ObjectContext.SaveChanges() In this simplified example I created two tables, Contacts and Employers, and one view Contacts_x_Employers which allows me to insert or retrieve rows into/from these two tables at once. The Tables only have a Name and an ID attributes and the view is based on a join of both: CREATE VIEW [dbo].[Contacts_x_Employers] AS SELECT dbo.Contacts.ContactName, dbo.Employers.EmployerName FROM dbo.Contacts INNER JOIN dbo.Employers ON dbo.Contacts.EmployerID = dbo.Employers.EmployerID And has this trigger: Create TRIGGER C_x_E_Inserts ON Contacts_x_Employers INSTEAD of INSERT AS BEGIN SET NOCOUNT ON; insert into Employers (EmployerName) select i.EmployerName from inserted i where not i.EmployerName in (select EmployerName from Employers) insert into Contacts (ContactName, EmployerID) select i.ContactName, e.EmployerID from inserted i inner join employers e on i.EmployerName = e.EmployerName; END GO The .NET Code follows: using (var Context = new TriggersTestEntities()) { Contacts_x_Employers CE1 = new Contacts_x_Employers(); CE1.ContactName = "J"; CE1.EmployerName = "T"; Contacts_x_Employers CE2 = new Contacts_x_Employers(); CE1.ContactName = "W"; CE1.EmployerName = "C"; Context.Contacts_x_Employers.AddObject(CE1); Context.Contacts_x_Employers.AddObject(CE2); Context.SaveChanges(); //? line with error } SSDL and CSDL (the view nodes): <EntityType Name="Contacts_x_Employers"> <Key> <PropertyRef Name="ContactName" /> <PropertyRef Name="EmployerName" /> </Key> <Property Name="ContactName" Type="varchar" Nullable="false" MaxLength="50" /> <Property Name="EmployerName" Type="varchar" Nullable="false" MaxLength="50" /> </EntityType> <EntityType Name="Contacts_x_Employers"> <Key> <PropertyRef Name="ContactName" /> <PropertyRef Name="EmployerName" /> </Key> <Property Name="ContactName" Type="String" Nullable="false" MaxLength="50" Unicode="false" FixedLength="false" /> <Property Name="EmployerName" Type="String" Nullable="false" MaxLength="50" Unicode="false" FixedLength="false" /> </EntityType> The Visual Studio solution and the SQL Scripts to re-create the whole application can be found in the TestViewTrggers.zip at ftp://JulioSantos.com/files/TriggerBug/. I appreciate any assistance that can be provided. I already spent days working on this problem.

  • Unit testing - how do I test a function that returns random output?

    - by Extrakun
    I have a function which takes in two parameters, and returns one or the other 50% of the time. The unit test for this should determine that both parameters could be returned. Luckily, I don't need to prove that the probability for each is 50% but I do need to show that both parameters are possible to be returned. How do I write a test case for this function?

  • Changing scaling of MATLAB Figure

    - by Phil
    I have a figure that displays 20,000 points on the x-axis. So it labels the x-axis from 0 ... 20,000. However, now I would like to scale it from 0 to 50. But when I try to do this in the plot window it just shows me the first 50 points, instead of changing the scale. Is there any straightforward way to do that in MATLAB?

  • how to refactor tricky logic involving consecutive sets?

    - by keruilin
    The rule at work here is that users can be awarded badges for a streak of 10, 20, and 30. If the user has a streak over 30, such as 40 or 50, then the logic must be that it only awards a 10-streak badge for 40 and a 20-streak badge for 50, and so on. def check_win_streak(streak) badge = 10 while badge < badge::MAX_STREAK_BADGE_SIZE do # MAX_STREAK_BADGE_SIZE = 30 if streak < badge then break end if (streak % badge == 0) then award_streak_badge(badge) end badge += 10 end end

    Hello, I have two comma separated lists:- 36,189,47,183,65,50 65,50,189,47 The question is how to compare the two in classic ASP in order to identify and return any values that exist in list 1 but that don't exist in list 2 bearing in mind that associative arrays aren't available. E.g., in the above example I would need the return value to be 36,183 Thanks
