  • Binding Data to a TextBlock using Domain Data Source

    - by TFisher
    I have a map with hotspots for each state (done in Expression Blend). I capture each MouseEnter of the state (1 thru 50). I pass that into my Domain Data Source: Dim activebox As Path = TryCast(sender, Path) activebox.Fill = mouseOverColor Dim StateID As Integer = CInt(Right(activebox.Name, 2)) Dim _StateContext As New StateContext myDataGrid.ItemsSource = _StateContext.States _StateContext.Load(_StateContext.GetStateByStateIDQuery(StateID.Text)) The above works fine for a datagrid, listbox and even a dataform. But I created a popup with a stackpanel that has textblocks. popupStatesBox.DataContext = ?????????????? popupStatesBox.IsOpen = True 'popup does open but has no data -- popupStatesBox.xaml <Popup x:Name="popupStatsBox" Margin="8,35,0,8" DataContext="{Binding}" IsOpen="false" Width="268" HorizontalAlignment="Left"> <StackPanel x:Name="Layout" Background="Black"> <TextBlock x:Name="tbState" Text="{Binding StateName /> <TextBlock x:Name="tbAbbrev" Text="{Binding Abbreviation}" /> </StackPanel> </Popup> How do I get the textblocks to display the values from the _StateContext. StackPanel has DataContext but no ItemsSource. What am I missing?

  • Finding min and max values

    - by user01
    I am trying to write a simple program that reads integers from a data file and outputs the minimum and maximum value. The first integer of the input file will indicate how many more integers will be read, and then the integers will be listed. My program compiles without any problem, however, it returns values that are not part of the set in my test data file. Could anyone help with diagnose this issue? int main(){ FILE *fp = fopen("data.txt", "r"); int count; int num; int i; int min = 0; int max = 0; fscanf (fp, "%d", &count); for (i = 0; i < count; i++) fscanf( fp, "%d", &i); { if (num < min) min = num; if (num > max) max = num; } fclose (fp); printf("Of the %d integers, the minimum value is %d and the maximum value is %d \n", count, min, max);}

  • P6 Architecture - Register renaming aside, does the limited user registers result in more ops spent

    - by mrjoltcola
    I'm studying JIT design with regard to dynamic languages VM implementation. I haven't done much Assembly since the 8086/8088 days, just a little here or there, so be nice if I'm out of sorts. As I understand it, the x86 (IA-32) architecture still has the same basic limited register set today that it always did, but the internal register count has grown tremendously, but these internal registers are not generally available and are used with register renaming to achieve parallel pipelining of code that otherwise could not be parallelizable. I understand this optimization pretty well, but my feeling is, while these optimizations help in overall throughput and for parallel algorithms, the limited register set we are still stuck with results in more register spilling overhead such that if x86 had double, or quadruple the registers available to us, there may be significantly less push/pop opcodes in a typical instruction stream? Or are there other processor optmizations that also optimize this away that I am unaware of? Basically if I've a unit of code that has 4 registers to work with for integer work, but my unit has a dozen variables, I've got potentially a push/pop for every 2 or so instructions. Any references to studies, or better yet, personal experiences?

  • function's return address is different from its supposed value, buffer overflow,

    - by ultrajohn
    Good day everyone! I’m trying to understand how buffer overflow works. I’m doing this for my project in a computer security course I’m taking. Right now, I’m in the process of determining the address of the function’s return address which I’m supposed to change to perform a buffer overflow attack. I’ve written a simple program based from an example I’ve read in the internet. What this program does is it creates an integer pointer that will be made to point to the address of the function return address in the stack. To do this, (granted I understand how a function/program variables get organized in the stack), I add 8 to the buffer variable’ address and set it as the value of ret. I’m not doing anything here that would change the address contained in the location of func’s return address. here's the program: Output of the program when gets excecuted: As you can see, I’m printing the address of the variables buffer and ret. I’ve added an additional statement printing the value of the ret variable (supposed location of func return address, so this should print the address of the next instruction which will get executed after func returns from execution). Here is the dump which shows the supposed address of the instruction to be executed after func returns. (Underlined in green) As you can see, that value is way different from the value printed contained in the variable ret. My question is, why are they different? (of course in the assumption that what I’ve done are all right). Else, what have I done wrong? Is my understanding of the program’s runtime stack wrong? Please, help me understand this. My project is due nextweek and I’ve barely touched it yet. I’m sorry if I’m being demanding, I badly need your help.

  • How to continuously scroll content within a DIV using jQuery?

    - by Camsoft
    Aim The aim is to a have a container DIV with a fixed height and width and have the HTML content within that DIV automatically scroll vertically continuously. Question Basically I've created the code below using jQuery to scroll (move) the child DIV vertically upwards until its outside the bounding parent box where the animation then completes which triggers an event handler which resets the position of the child DIV and starts the process again. This works fine, so the content scrolls up leaving a blank space and then starts from the bottom again and scrolls up. The problem I have is that the requirements for this is for the content to appear as if it was continuously repeating, see below diagram to better explain this, is there a way to do this? (I don't want to use 3rd party plug ins or libraries other than jQuery): What I have so far The HTML: <div id="scrollingContainer"> <div class="scroller"> <h1>This is a title</h1> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse at orci mi, id gravida tellus. Integer malesuada ante sit amet enim pulvinar congue. Donec pulvinar dolor et arcu posuere feugiat id et felis.</p> <p>More content....</p> </div> </div> The CSS: #scrollingContainer{ height: 300px; width: 300px; overflow: hidden; } #scrollingContainer DIV.scroller{ position: relative; } The JavaScript: /** * Scrolls the content DIV */ function scroll() { if($('DIV.scroller').height() > $('#scrollingContainer').height()) { var t = $('DIV.scroller').position().top + $('DIV.scroller').height(); /* Animate */ $('DIV.scroller').animate( { top: '-=' + t + 'px' } , 4000, 'linear', animationComplete); } } function animationComplete() { $(this).css('top', $('#scrollingContainer').height()); scroll(); }

  • Big sinatra problems

    - by Joel M.
    Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?

  • How to code a URL shortener?

    - by marco92w
    I want to create a URL shortener service where you can write a long URL into an input field and the service shortens the URL to "http://www.example.org/abcdef". Instead of "abcdef" there can be any other string with six characters containing a-z, A-Z and 0-9. That makes 56 trillion possible strings. My approach: I have a database table with three columns: id, integer, auto-increment long, string, the long URL the user entered short, string, the shortened URL (or just the six characters) I would then insert the long URL into the table. Then I would select the auto-increment value for "id" and build a hash of it. This hash should then be inserted as "short". But what sort of hash should I build? Hash algorithms like MD5 create too long strings. I don't use these algorithms, I think. A self-built algorithm will work, too. My idea: For "http://www.google.de/" I get the auto-increment id 239472. Then I do the following steps: short = ''; if divisible by 2, add "a"+the result to short if divisible by 3, add "b"+the result to short ... until I have divisors for a-z and A-Z. That could be repeated until the number isn't divisible any more. Do you think this is a good approach? Do you have a better idea?

  • PostgreSQL: Rolling back a transaction within a plpgsql function?

    - by jamieb
    Coming from the MS SQL world, I tend to make heavy use of stored procedures. I'm currently writing an application uses a lot of PostgreSQL plpgsql functions. What I'd like to do is rollback all INSERTS/UPDATES contained within a particular function if I get an exception at any point within it. I was originally under the impression that each function is wrapped in it's own transaction and that an exception would automatically rollback everything. However, that doesn't seem to be the case. I'm wondering if I ought to be using savepoints in combination with exception handling instead? But I don't really understand the difference between a transaction and a savepoint to know if this is the best approach. Any advice please? CREATE OR REPLACE FUNCTION do_something( _an_input_var int ) RETURNS bool AS $$ DECLARE _a_variable int; BEGIN INSERT INTO tableA (col1, col2, col3) VALUES (0, 1, 2); INSERT INTO tableB (col1, col2, col3); VALUES (0, 1, 'whoops! not an integer'); -- The exception will cause the function to bomb, but the values -- inserted into "tableA" are not rolled back. RETURN True; END; $$ LANGUAGE plpgsql;

  • Asp.net Login Status Question: It Aint Working

    - by contactmatt
    I'm starting to use Role Management in my website, and I'm current following along on the tutorial from http://www.asp.net/Learn/Security/tutorial-02-vb.aspx . I'm having a problem with the asp:LoginStatus control. It is not telling me that I am currently logged in after a successful login.

  • Sorting ArrayList - IndexOutOfBoundsException -Java

  • Array: mathematical sequence

    - by VaioIsBorn
    An array of integers A[i] (i 1) is defined in the following way: an element A[k] ( k 1) is the smallest number greater than A[k-1] such that the sum of its digits is equal to the sum of the digits of the number 4* A[k-1] . You need to write a program that calculates the N th number in this array based on the given first element A[1] . INPUT: In one line of standard input there are two numbers seperated with a single space: A[1] (1 <= A[1] <= 100) and N (1 <= N <= 10000). OUTPUT: The standard output should only contain a single integer A[N] , the Nth number of the defined sequence. Input: 7 4 Output: 79 Explanation: Elements of the array are as follows: 7, 19, 49, 79... and the 4th element is solution. I tried solving this by coding a separate function that for a given number A[k] calculates the sum of it's digits and finds the smallest number greater than A[k-1] as it says in the problem, but with no success. The first testing failed because of a memory limit, the second testing failed because of a time limit, and now i don't have any possible idea how to solve this. One friend suggested recursion, but i don't know how to set that. Anyone who can help me in any way please write, also suggest some ideas about using recursion/DP for solving this problem. Thanks.

    Hi, I'm trying to call a thread on a button click (btn_more) but i cant get it right. The thread is to get some data and update the images. The problem i have is if i only update 4 or 5 images then it works fine. But if i load more than 5 images i will get a force close. At times when the internet is slow I will face the same problem too. Can please help me to solve this problem or provide me some guidance?

  • How to dispatch a new property value in an object to the same property of two other objects

    - by WPFadvocate
    In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects. Edited: here is my tentative code for multibinding, with the false hope that it would work without additional code: // create the multibinding MultiBinding mb = new MultiBinding() { Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }; // create individual bindings to associate object_2 and object_3 to object_1 Binding b2 = new Binding() { Source = object_2, Path = new PropertyPath("X") }; Binding b3 = new Binding() { Source = object_3, Path = new PropertyPath("X") }; // add individual bindings to multibinding mb.Bindings.Add(b2); mb.Bindings.Add(b3); // bind object_2 and _3 to object_1 BindingOperations.SetBinding(object_1, TypeObject_1.XProperty, mb); But actually, there is a runtime error, saying the binding set by the last instruction is lacking a converter. But again I don't know how to write this converter (there is nothing to convert (as this is the case in the related MS sample of code linking 3 rgb properties to a color property), only to forward the value of the property changed to the two other properties). I understand I could solve the problem by creating an X_Changed event in the 3 types and then have each object registering to the two other objects event. I don't like this "manual" way and would prefer to bind the 3 properties together.

  • ASP.Net MVC Json Result: Parameters passed to controller method issue

    - by Moskie
    I'm having a problem getting a controller method that returns a JsonResult to accept parameters passed via the JQuery getJSON method. The code I’m working on works fine when the second parameter ("data") of the getJSON method call is null. But when I attempt to pass in a value there, it seems as if the controller method never even gets called. In this example case, I just want to use an integer. The getJSON call that works fine looks like this: $.getJSON(”/News/ListNewsJson/”, null, ListNews_OnReturn); The controller method is like this: public JsonResult ListNewsJson(int? id) { … return Json(toReturn); } By putting a breakpoint in the ListNewsJson method, I see that this method gets called when the data parameter of getJSON is null, but when I replace it with value, such as, say, 3: $.getJSON(”/News/ListNewsJson/”, 3, ListNews_OnReturn); … the controller method/breakpoint is never hit. Any idea what I'm doing wrong? I should also mention that the controller method works fine if I manually go to the address via my browser ("/News/ListNewsJson/3").

  • Displaying indexed png- files out of NSArray on the iphone screen

    - by Thomas Hülsmann
    Hi, i like to create an artwork counter- display on an iphone, diplaying 0 to 9. The 10 digits are 10 png- files with the numbers 0 to 9 as their artwork content. The 10 png- files are implemented by using NSArray. Following you'll find the implementation- code: zahlenArray = [NSArray arrayWithObjects: [UIImage imageNamed:@"ziffer-0.png"], [UIImage imageNamed:@"ziffer-1.png"], [UIImage imageNamed:@"ziffer-2.png"], [UIImage imageNamed:@"ziffer-3.png"], [UIImage imageNamed:@"ziffer-4.png"], [UIImage imageNamed:@"ziffer-5.png"], [UIImage imageNamed:@"ziffer-6.png"], [UIImage imageNamed:@"ziffer-7.png"], [UIImage imageNamed:@"ziffer-8.png"], [UIImage imageNamed:@"ziffer-9.png"], nil]; As an index for the 10 digitis I use an integer variable, initializing with 0: int counter = 0; Furthermore I declare an UIImageview programmaticaly: UIImageView *zahlenEinsBisNeun; The implementation code for the UIImageview is: zahlenEinsBisNeun = [UIImage alloc] initWithFrame:CGRectMake(240, 50, 200, 200)]; ???????????????????????????????????????? [self.view addSubview:zahlenEinsBisNeun]; [zahlenEinsBisNeun release]; There, where you see the questionmarks, I don't know how to write the code, to retrieve my content artworks 0 to 9 from NSArray with the index "counter" and make it visible on my iphone screen by using .... addSubview:zahlenEinsBisNeun ... Can anybody help??? My thanks for your support in advance Thomas Hülsmann

  • How do I access variable values from one view controller in another?

    - by Thomas
    Hello all, I have an integer variable (time) in one view controller whose value I need in another view controller. Here's the code: MediaMeterViewController // TRP - On Touch Down event, start the timer -(IBAction) startTimer { time = 0; // TRP - Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; [timer retain]; // TRP - Retain timer so it is not accidentally deallocated } // TRP - Method to update the timer display -(void)updateTimer { time++; // NSLog(@"Seconds: %i ", time); if (NUM_SECONDS == time) [timer invalidate]; } // TRP - On Touch Up Inside event, stop the timer, decide stress level, display results -(IBAction) btn_MediaMeterResults { [timer invalidate]; NSLog(@"Seconds: %i ", time); ResultsViewController *resultsView = [[ResultsViewController alloc] initWithNibName:@"ResultsViewController" bundle:nil]; [self.view addSubview:resultsView.view]; } And in ResultsViewController, I want to process time based on its value ResultsViewController - (void)viewDidLoad { if(time < 3) {// Do something} else if ((time > 3) && (time < 6)) {// Do something else} //etc... [super viewDidLoad]; } I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated. Thanks! Thomas

  • Problem with custom Equality and GetHashCode in a mutable object

    - by Shimmy
    Hello! I am using Entity Framework in my application. I implemented with the partial class of an entity the IEquatable<T> interface: Partial Class Address : Implements IEquatable(Of Address) 'Other part generated Public Overloads Function Equals(ByVal other As Address) As Boolean _ Implements System.IEquatable(Of Address).Equals If ReferenceEquals(Me, other) Then Return True Return AddressId = other.AddressId End Function Public Overrides Function Equals(ByVal obj As Object) As Boolean If obj Is Nothing Then Return MyBase.Equals(obj) If TypeOf obj Is Address Then Return Equals(DirectCast(obj, Address)) Else Return False End Function Public Overrides Function GetHashCode() As Integer Return AddressId.GetHashCode End Function End Class Now in my code I use it this way: Sub Main() Using e As New CompleteKitchenEntities Dim job = e.Job.FirstOrDefault Dim address As New Address() job.Addresses.Add(address) Dim contains1 = job.Addresses.Contains(address) 'True e.SaveChanges() Dim contains2 = job.Addresses.Contains(address) 'False 'The problem is that I can't remove it: Dim removed = job.Addresses.Remoeve(address) 'False End Using End Sub Note (I checked in the debugger visualizer) that the EntityCollection class stores its entities in HashSet so it has to do with the GetHashCode function, I want it to depend on the ID so entities are compared by their IDs. The problem is that when I hit save, the ID changes from 0 to its db value. So the question is how can I have an equatable object, being properly hashed. Please help me find what's wrong in the GetHashCode function (by ID) and what can I change to make it work. Thanks a lot.

  • multiple keys and values with google-collections

    - by flash3000
    Hello, I would like use google-collection in order to save the following file in a Hash with multiple keys and values Key1_1, Key2_1, Key3_1, data1_1, 0, 0 Key1_2, Key2_2, Key3_2, data1_2, 0, 0 Key1_3, Key2_3, Key3_3, data1_3, 0, 0 Key1_4, Key2_4, Key3_4, data1_4, 0, 0 The first three columns are the different keys and the last two integer are the two different values. I have already prepare a code which spilt the lines in chunks. import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; public class HashMapKey { public static void main(String[] args) throws FileNotFoundException, IOException { String inputFile = "inputData.txt"; BufferedReader br = new BufferedReader(new FileReader(inputFile)); String strLine; while ((strLine = br.readLine()) != null) { String[] line = strLine.replaceAll(" ", "").trim().split(","); for (int i = 0; i < line.length; i++) { System.out.print("[" + line[i] + "]"); } System.out.println(); } } } Unfortunately, I do not know how to save these information in google-collection? Thank you in advance. Best regards,

  • Generating equals / hashcode / toString using annotation

    - by Bruno Bieth
    I believe I read somewhere people generating equals / hashcode / toString methods during compile time (using APT) by identifying which fields should be part of the hash / equality test. I couldn't find anything like that on the web (I might have dreamed it ?) ... That could be done like that : public class Person { @Id @GeneratedValue private Integer id; @Identity private String firstName, lastName; @Identity private Date dateOfBirth; //... } For an entity (so we want to exlude some fields, like the id). Or like a scala case class i.e a value object : @ValueObject public class Color { private int red, green, blue; } Not only the file becomes more readable and easier to write, but it also helps ensuring that all the attributes are part of the equals / hashcode (in case you add another attribute later on, without updating the methods accordingly). I heard APT isn't very well supported in IDE but I wouldn't see that as a major issue. After all, tests are mainly run by continuous integration servers. Any idea if this has been done already and if not why ? Thanks

  • Lazarus - why I can't assign event to run-time component?

    - by Garret Raziel

I have searched and think that this is legal expression in Delphi. I want simply to registrate OnTlacitkoClick as tlac.OnClick event,not to call this procedure. Is there somethink wrong with the code or must I do it different in Lazarus/Freepascal? Thanks.

  • Why collection literals ?

    - by Green Hyena
    Hi fellow Java programmers. From the various online articles on Java 7 I have come to know that Java 7 will be having collection literals like the following: List<String> fruits = [ "Apple", "Mango", "Guava" ]; Set<String> flowers = { "Rose", "Daisy", "Chrysanthemum" }; Map<Integer, String> hindiNums = { 1 : "Ek", 2 : "Do", 3 : "Teen" }; My questions are: 1] Wouldn't it have been possible to provide a static method of in all of the collection classes which could be used as follows: List<String> fruits = ArrayList.of("Apple", "Mango", "Guava"); IMO this looks as good as the literal version and is also reasonably concise. Why then did they have to invent a new syntax? 2] When I say List<String> fruits = [ "Apple", "Mango", "Guava" ]; what List would I actually get? Would it be ArrayList or LinkedList or something else? Thanks.
