  • How to rate a connect four game situation in java

    - by MrPink
    Hey, I am trying to write a simple AI for a "Get four" game. The basic game principles are done, so I can throw in coins of different color, and they stack on each other and fill a 2D Array and so on and so forth. until now this is what the method looks like: public int insert(int x, int color) //0 = empty, 1=player1 2=player2" X is the horizontal coordinate, as the y coordinate is determined by how many stones are in the array already, I think the idea is obvious. Now the problem is I have to rate specific game situations, so find how many new pairs, triplets and possible 4 in a row I can get in a specific situation to then give each situation a specific value. With these values I can setup a "Game tree" to then decide which move would be best next (later on implementing Alpha-Beta-Pruning). My current problem is that I can't think of an efficient way to implement a rating of the current game situation in a java method. Any ideas would be greatly appreciated! greetings from Germany Mr. Pink

  • Globals across modules

    - by Coder1
    Wow, this seems so basic, but I can't get it to work. All I need to do is store a global dict which can be accessed and modified from other modules & threads. What's the "best practices" way of achieving this? test.py import testmodule class MyClassA(): def __init__(self, id): self.id = id if __name__ == '__main__': global classa_dict classa_dict = {} classa_dict[1] = MyClassA(1) classa_dict[2] = MyClassA(2) testing = testmodule.TestModule() testmodule.py class TestModule(): def __init__(self): global classa_dict print classa_dict[2] output $ python test.py Traceback (most recent call last): File "test.py", line 13, in <module> testing = testmodule.TestModule() File "/path/to/project/testmodule.py", line 4, in __init__ print classa_dict[2] NameError: global name 'classa_dict' is not defined

  • How to retain focus on an editable html after deleting an element.

    - by Lukasz
    Hello, I have a website with design mode on (aka. content editable = true) with some basic text on it. To that site I hooked up a shortcut so that at any point in the text I can insert an input box that serves me as an autocomplete. For that input however I want it to disappear right after I hit ENTER so that I can continue typing. It is an easy task to just make the input box disappear but I always loose focus from my document. I would greatly appreciate any suggestions on how to make this work?

  • A Simple C# DLL - how do I call it from Excel, Access, VBA, VB6 ?

    - by divinci
    Hi all, I have a simple class library written in c#. using System; namespace TestDll { public class Test { public string HelloWorld { get { return "Hello World"; } } } } My question is how can I call this HelloWorld function from Microsoft Office Visual Basic (which I think is VB6)? My first step was to add the DLL as a reference - but on browsing and selecting the compiled DLL the message "Can't add a reference to the specified file." was thrown. Can anyone point me in the right direction as to why/how to get this working? Thanks in advance SO!

  • WPF InotifyPropertyChanged and view models

    - by Joel Barsotti
    So I think I'm doing something pretty basic. I know why this doesn't work, but it seems like there should be a straight foward way to make it work. code: private string fooImageRoot; // .... public BitmapImage FooImage { get { URI imageURI = new URI(Path.Combine(fooImageRoot, CurrentFooTypes.FooObject.FooImageName)); return imageURI; } } So CurrentFOoTypes and FooObject also supports INotifyPropertyChanged. So If I bind a TextBlock to CurrentFooTypes.FooObject.FooImageName, if either fooObject or FooImageName change the textblock updates. How can I subscribe my viewmodel object to recieve updates in a similiar fasion.

  • SQL Server Mapping a user to a login and adding roles programmatically

    - by user163457
    In my SQL Server 2005 server I create databases and logins using Management Studio. My application requires that I give a newly created user read and write permissions to another database. To do this I right-click the newly created login, select properties and go to User Mapping. I put a check beside the database to map this login to the db and select db_datareader and db_datawriter as the roles to map. Can this be done programmatically? I've read about using Alter User and sp_change_users_login but I'm having problems getting these to work, since sp_change_users_login has been deprecated so I'd prefer to use Alter User. Please note my understanding of SQL Server database users/logins/roles is basic

  • Still not understanding SVN Repositories in eclipse

    - by jax
    I am about to import my project into svn but don't want to stuff it up. My structure is like this: Repositories: /var/svn/client_name1/ /var/svn/client_name2/ Project directories under /var/svn/client_name1/ project1/ trunk/ branches/ tags/ project2/ trunk/ branches/ tags/ My Apache config looks like this: <Location /svn> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthType Basic AuthName "My Repository" AuthUserFile /etc/svnpass Require valid-user AuthzSVNAccessFile /etc/svnauth </Location> Now I can access my svn repository http://mysite.com/svn/client_name1/ however, there are no projects displayed here, just a Revision 0 message (is that correct)? I can connect to the repository in eclipse using the same url. If I want to place an existing project into the repository what url do I use? http://mysite.com/svn/client_name1/project1 OR http://mysite.com/svn/client_name1/project1/trunk

  • Reduce the number of queries in EF

    - by Gio2k
    I have the following Model: Entities: Product (Contains basic data for products: price, etc) Attribute (Contains data for all possible optional attributes) ProductAttribute (Contains data for optional attributes of a product, eg. Color, Model, Size). ProductAttribute is essentially a many to many relationship with payload (ProductId, AttributeID, Value) And this piece of code: private static void ListAttributes(Product p) { p.ProductAttributes.Load(); foreach (var att in p.ProductAttributes) { att.Attribute.load(); Console.WriteLine("\tAttribute Name:{0} - Value {1}", att.Attribute.Name, att.AttributeValue); } } This piece of code will fire a query for each time the att.Attribute.Load() method is called in the foreach loop, only so i can get display the name of the attribute. I would like to fetch the Attribute.Name together with the query that fetches all attribute values, i.e. join ProductAttribute and Attribute. Is there any way to achieve this within my method?

  • Trouble refreshing UITableView

    - by aahrens
    I'm trying to develop a basic GPA Calculator. I have an AllCourses class that holds Course objects. I have an AllCourses object in my CalcAppDelegate. In my ThirdViewController I can successfully update the number of Courses in my AllCourses object. However, the problem I'm having is that when I switch to the RootViewController the UITable isn't being repopulated with the updated Courses that were added. I tried [self reloadData] in the viewWillAppear in my RootViewController but it caused my app to close. I didn't use IB to create the views so I think it could be the case that I don't have things hooked up correctly. I did it programatically. Does anyone see anything I'm missing in my code? Here is the link to my project http://files.me.com/aahrens/q0odzi

  • Perl Regex Mismatch Issue

    - by Russell C.
    This is a really basic regex question but since I can't seem to figure out why the match is failing in certain circumstances I figured I'd post it to see if anyone else can point out what I'm missing. I'm trying to pull out the 2 sets of digits from strings of the form: 12309123098_102938120938120938 1321312_103810312032123 123123123_10983094854905490 38293827_1293120938129308 I'm using the following code to process each string: if($string && $string =~ /^(\d)+_(\d)+$/) { if(IsInteger($1) && IsInteger($2)) { print "success ('$1','$2')"; } else { print "fail"; } } Where the IsInterger() function is as follows: sub IsInteger { my $integer = shift; if($integer && $integer =~ /^\d+$/) { return 1; } return; } This function seems to work most of the time but fails on the following for some reason: 1287123437_1268098784380 1287123437_1267589971660 Any ideas on why these fail while others succeed? Thanks in advance for your help!

  • Reporting / BI Framework for social websites

    - by Ryan
    I'm looking for ideas / open source frameworks to use for creating individual Analytics for user profiles and all the other profile types. Users will have different custom metrics, businesses willl have seperate metrics, the admin section will have seperate, Advertises will have seperate, etc. So basically the goal is to have 1 framework in place for all Analytics, which will be custom user to user and even use that for the system analytic needs also. It will include data analytics as there will be user ratings/reviews to perfomr data mining on for businesses, USers will have basic reporting on their needs (like friend demographics, filter by different preferences, etc). System is being developed in cakePhp. Thanks.

  • output all data from db to a php page

    - by Sarit
    Hi, I'm a real beginner with PHP & mysql. Just for studying and for a simple example at school I would like to work this simple query and possibly output all the rows (or maybe even one) to a very basic output on a php page: <?php $user= "root"; $host="localhost"; $password=""; $database = "PetCatalog"; $cxn = mysqli_connect($host,$user,$password,$database) or die ("couldn’t connect to server"); $query = "SELECT * FROM Pet"; $result = mysql_query($cxn,$query) or die ("Couldn’t execute query."); $row = mysqli_fetch_assoc($result); echo "$result"; ?> this is the error message i've been getting: Warning: mysql_query() expects parameter 1 to be string, object given in C:\xampplite\htdocs\myblog\query.php on line 18 Couldn’t execute query. What should I do? Thanks!

  • Segmentation fault when using files C++

    - by Popa Mihai
    I am using ubuntu 12.04. I have been trying a few IDE's for simple C++ school projects. However, with codelite, anjuta and kdevelop I encountered a problem: when I am trying to read / write in files I get segmentation fault: core dumped. I am using a basic source: #include<stdio.h> FILE*f=fopen("test.in","r"); FILE*g=fopen("test.out","w"); int main () { int a,b; fscanf(f,"%d %d",&a,&b); fprintf(g,"%d\n",a+b); fclose(f); fclose(g); return 0; } I have to say that programs with stdin/stdout work well. Thank you,

  • Recursive Functions for Beginners?

    - by cam
    I'm looking for a few recursive function examples, preferably ones that show increase in complexity. I understand basic recursive functions, but I'm having trouble implementing them in my code. I've never used them in my code before, and I know it doesn't always call for it, but I'd like to try. Is there a good resource with examples, and maybe challenges of some sort? Or even some simple math problems (Project Euler-style?) that I could use recursion on? For examples, I prefer C#, but anything works.

  • Alternatives to UIWebView for rich content?

    - by ojreadmore
    In my app, I am displaying 4 "tabs", each are local content through a UIWebView. I create HTML markup from my simple data. This is slow to load and I'm trying to speed it up. I'm using UIWebView to accomplish these: 1. hyperlinks 2. some styling - font colors 3. HTML tables Writing my own class to handle this is okay for (1.) hyperlinks - I can use a touch event to call a method. And (2.) styling - I can use UILables to do basic formatting, no biggie here. BUT what I really love about the UIWebViews is the (3.) HTML tables! I find it troublesome to line up the UILabels in a way that mimics HTML Tables, for instance, one cell's height in a row changes the height of all cells. I'm looking for another perspective or knowledge of an alternative.

  • Force Response to Download File(s) to Desktop with Ruby?

    - by viatropos
    I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and remote app resizes image image downloads automatically locally to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby. What's the basic concept behind this? What if I wanted to do this for multiple files? Åssuming I can get multiple files uploaded no problem, how can I download all of them automatically?

  • C++ Word-Number to int

    - by Andrew
    I'm developing a program that makes basic calculations using words instead of numbers. E.g. five + two would output seven. The program becomes more complex, taking input such as two_hundred_one + five_thousand_six (201 + 5006) Through operator overloading methods, I split each number and assign it to it's own array index. two would be [0], hundred is [1], and one is [2]. Then the array recycles for 5006. My problem is, to perform the actual calculation, I need to convert the words stored in the array to actual integers. I have const string arrays such as this as a library of the words: const string units[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; const string teens[] = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; const string tens[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; If my 'token' array has stored in it two hundred one in index 0, 1, and 2, I'm not sure what the best way to convert these to ints would involve.

  • Sprite background image lags on mouse hover

    - by user351342
    I have basic DOM menu that has sprite background images for the first level of "LI"s. It works just fine, but I guess there is some problem and instead of switching the image right away on hover it goes blank and after about a second the hover image "appears" (shifts). That happens only on first hovering. After that it's smooth like it's supposed to be. Refresh the page and there it is again... Frustrating... Here is a link to check it out: http://goo.gl/6FAM The problem exist on Firefox v3.6.3. Chrome 5.0.375 and IE 8.0.7600 don't have this issue. Any ideas?

  • Generics and reflection in Java

    - by Ragesh
    This is probably a very basic question, but I'm really new to generics in Java and I'm having a hard time altering my thought process from the way things are done in C#, so bear with me. I'm trying to build a generic repository in Java. I've created an IRepository interface that looks like this: public interface IRepository<T extends IEntity> And a Repository class that looks like this: public class Repository<T extends IEntity> implements IRepository<T> Now, from within the constructor of my Repository class, I'd like to be able to "divine" the exact type of T. For example, if I instantiated a repository like this: IRepository<MyClass> repo = new Repository<MyClass>(); I'd like to know that T is actually MyClass. This is trivial in C#, but obviously generics are a totally different beast in Java and I can't seem to find anything that would help me do this.

Im now trying to get the object from json through $.getJSON function getEventData() { var result = ''; $.getJSON("ajax.php?cmd=getbydate&fromdate=&todate=", function(data){ result = data; }); return result; } Problem is that result isn't set in the callback function for obvious reasons. Do you guys have a solution for this?

  • Simple Obj-C Memory Management Question

    - by yar
    This is from some sample code from a book // On launch, create a basic window - (void)applicationDidFinishLaunching:(UIApplication *)application { UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[[HelloController alloc] init]]; [window addSubview:nav.view]; [window makeKeyAndVisible]; } But a release is never called for window nor for nav. Release should be called since alloc was called, right? If #1 is right, then I would need to store a reference to each of these in an instance variable in order to release them in the dealloc? Perhaps I'm wrong all around...

  • Multiple user database design

    - by dieguitoweb
    I have to develop a basic social network for an academic purpose; but I need some tips for the users management.. The users are subdivided into 3 groups with different privilege: admins,analysts and standards users. For every user should be stored into the database the following information: name,lastname,e-mail,age,password. I'm not quite sure how I should design the database between theese two solutions: 1)one table called 'users' with the 'role' attribute that explain what a user can do and what can't do, and the permissions are managed via php 2)every application user is a database user created with the query 'CREATE ROLE' (It's a postgres database) and he has permissions on some tables granted with the 'GRANT' statement You should take into account that the project is for a database exam.. thanks

  • Find value within a range in lookup table

    - by francis
    I have the simplest problem to implement, but so far I have not been able to get my head around a solution in Python. I have built a table that looks similar to this one: 501 - ASIA 1262 - EUROPE 3389 - LATAM 5409 - US I will test a certain value to see if it falls within these ranges, 389 -> ASIA, 1300 -> LATAM, 5400 -> US. A value greater than 5409 should not return a lookup value. I normally have a one to one match, and would implement a dictionary for the lookup. But in this case I have to consider these ranges, and I am not seeing my way out of the problem. Maybe without providing the whole solution, could you provide some comments that would help me look in the right direction? It is very similar to a vlookup in a spreadsheet. I would describe my Python knowledge as somewhere in between basic to intermediate. Many thanks in advance.

  • Second Unit Test Not Running

    - by TomJ
    I am having trouble getting my Method B test to run. The logic is fine, but when the unit tests are run, only Method A will run. If Method A and B are switched in terms of spots, only Method B will run. So clearly the code is wrong at some point. Do I need to call method B's test from inside method A in order to get both unit tests to run? I'm pretty new to C#, so forgive my basic question. using redacted; using Microsoft.VisualStudio.TestTools.UnitTesting; using System; namespace UnitTests { [TestClass()] public class ClassTest { public TestContext TestContext{get;set;} [TestMethod()] public void MethodATest() { the unit test } [TestMethod()] public void MethodBTest() { the unit test } } }
