Secondly the BG image seems to be overlaying twice as in its stretched at the top then the full picture does display as it should. I did have it working but when trying to fix the pixel gap I must of messed something up but no idea what, so it is now going pear shape, lease help with both these situations :)?

  • Avoiding Agnostic Jagged Array Flattening in Powershell

    - by matejhowell
    Hello, I'm running into an interesting problem in Powershell, and haven't been able to find a solution to it. When I google (and find things like this post), nothing quite as involved as what I'm trying to do comes up, so I thought I'd post the question here. The problem has to do with multidimensional arrays with an outer array length of one. It appears Powershell is very adamant about flattening arrays like @( @('A') ) becomes @( 'A' ). Here is the first snippet (prompt is , btw): > $a = @( @( 'Test' ) ) > $a.gettype().isarray True > $a[0].gettype().isarray False So, I'd like to have $a[0].gettype().isarray be true, so that I can index the value as $a[0][0] (the real world scenario is processing dynamic arrays inside of a loop, and I'd like to get the values as $a[$i][$j], but if the inner item is not recognized as an array but as a string (in my case), you start indexing into the characters of the string, as in $a[0][0] -eq 'T'). I have a couple of long code examples, so I have posted them at the end. And, for reference, this is on Windows 7 Ultimate with PSv2 and PSCX installed. Consider code example 1: I build a simple array manually using the += operator. Intermediate array $w is flattened, and consequently is not added to the final array correctly. I have found solutions online for similar problems, which basically involve putting a comma before the inner array to force the outer array to not flatten, which does work, but again, I'm looking for a solution that can build arrays inside a loop (a jagged array of arrays, processing a CSS file), so if I add the leading comma to the single element array (implemented as intermediate array $y), I'd like to do the same for other arrays (like $z), but that adversely affects how $z is added to the final array. Now consider code example 2: This is closer to the actual problem I am having. When a multidimensional array with one element is returned from a function, it is flattened. It is correct before it leaves the function. And again, these are examples, I'm really trying to process a file without having to know if the function is going to come back with @( @( 'color', 'black') ) or with @( @( 'color', 'black'), @( 'background-color', 'white') ) Has anybody encountered this, and has anybody resolved this? I know I can instantiate framework objects, and I'm assuming everything will be fine if I create an object[], or a list<, or something else similar, but I've been dealing with this for a little bit and something sure seems like there has to be a right way to do this (without having to instantiate true framework objects). Code Example 1 function Display($x, [int]$indent, [string]$title) { if($title -ne '') { write-host "$title`: " -foregroundcolor cyan -nonewline } if(!$x.GetType().IsArray) { write-host "'$x'" -foregroundcolor cyan } else { write-host '' $s = new-object string(' ', $indent) for($i = 0; $i -lt $x.length; $i++) { write-host "$s[$i]: " -nonewline -foregroundcolor cyan Display $x[$i] $($indent+1) } } if($title -ne '') { write-host '' } } ### Start Program $final = @( @( 'a', 'b' ), @('c')) Display $final 0 'Initial Value' ### How do we do this part ??? ########### ## $w = @( @('d', 'e') ) ## $x = @( @('f', 'g'), @('h') ) ## # But now $w is flat, $w.length = 2 ## ## ## # Even if we put a leading comma (,) ## # in front of the array, $y will work ## # but $w will not. This can be a ## # problem inside a loop where you don't ## # know the length of the array, and you ## # need to put a comma in front of ## # single- and multidimensional arrays. ## $y = @( ,@('D', 'E') ) ## $z = @( ,@('F', 'G'), @('H') ) ## ## ## ########################################## $final += $w $final += $x $final += $y $final += $z Display $final 0 'Final Value' ### Desired final value: @( @('a', 'b'), @('c'), @('d', 'e'), @('f', 'g'), @('h'), @('D', 'E'), @('F', 'G'), @('H') ) ### As in the below: # # Initial Value: # [0]: # [0]: 'a' # [1]: 'b' # [1]: # [0]: 'c' # # Final Value: # [0]: # [0]: 'a' # [1]: 'b' # [1]: # [0]: 'c' # [2]: # [0]: 'd' # [1]: 'e' # [3]: # [0]: 'f' # [1]: 'g' # [4]: # [0]: 'h' # [5]: # [0]: 'D' # [1]: 'E' # [6]: # [0]: 'F' # [1]: 'G' # [7]: # [0]: 'H' Code Example 2 function Display($x, [int]$indent, [string]$title) { if($title -ne '') { write-host "$title`: " -foregroundcolor cyan -nonewline } if(!$x.GetType().IsArray) { write-host "'$x'" -foregroundcolor cyan } else { write-host '' $s = new-object string(' ', $indent) for($i = 0; $i -lt $x.length; $i++) { write-host "$s[$i]: " -nonewline -foregroundcolor cyan Display $x[$i] $($indent+1) } } if($title -ne '') { write-host '' } } function funA() { $ret = @() $temp = @(0) $temp[0] = @('p', 'q') $ret += $temp Display $ret 0 'Inside Function A' return $ret } function funB() { $ret = @( ,@('r', 's') ) Display $ret 0 'Inside Function B' return $ret } ### Start Program $z = funA Display $z 0 'Return from Function A' $z = funB Display $z 0 'Return from Function B' ### Desired final value: @( @('p', 'q') ) and same for r,s ### As in the below: # # Inside Function A: # [0]: # [0]: 'p' # [1]: 'q' # # Return from Function A: # [0]: # [0]: 'p' # [1]: 'q' Thanks, Matt

  • How can I connect to a mail server using SMTP over SSL using Python?

  • website creation - for non web programmers?

    - by Tim
    I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

  • How do I change variables from different classes?

    - by Dan T
    Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated. The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code of one: <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_marginRight="5dp" android:background="@drawable/addbeer"/> The buttons and TextView are all in main.xml. I have variables defined in a class called Global.java: package com.dantoth.drinkingbuddy; import android.app.Activity; public class Global extends Activity{ public static double StandardDrinks = 0; public static double BeerOunces = 12; public static double BeerPercentAlcohol = .05; public static double BeerDrink = BeerOunces * BeerPercentAlcohol; public static double BeerDrinkFinal = BeerDrink * 1.6666666; public static double ShotOunces = 1.5; public static double ShotPercentAlcohol = .4; public static double ShotDrink = ShotOunces * ShotPercentAlcohol; public static double ShotDrinkFinal = ShotDrink * 1.6666666; public static double WineOunces = 5; public static double WinePercentAlcohol = .12; public static double WineDrink = WineOunces * WinePercentAlcohol; public static double WineDrinkFinal = WineDrink * 1.6666666; public static double OtherOunces; public static double OtherPercentAlcohol; public static double OtherDrink = OtherOunces * (OtherPercentAlcohol * .01); public static double OtherDrinkFinal = OtherDrink * 1.6666666; public static double GenderConstant = 7.5; //9 for female public static double Weight = 180; public static double TimeDrinking = 60; public static double Hours = TimeDrinking / 60; public static double Bac = ((StandardDrinks / 2) * (GenderConstant / Weight)) - (0.017 * Hours); } The last variable is the important part. It calculates your BAC based on the factors involved. When I press the add beer button (Button01) I make it add 1 to StandardDrinks, simulating drinking one beer. The other variables in the Bac formula have values assigned to them in Global.java. The code that makes the beer button do stuff is in my regular class, drinkingbuddy.java: public class DrinkingBuddy extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Global.StandardDrinks = Global.StandardDrinks + Global.BeerDrinkFinal; Toast.makeText(DrinkingBuddy.this, "Mmmm... Beer", Toast.LENGTH_SHORT).show(); } }); By my perception, StandardDrinks should now have a value of 1. However, when I click the Calculate BAC button (Button05) it merely outputs the variable Bac as if StandardDrinks was still set to 0. Here is the code for the Calculate BAC button (Button05): Button button4 = (Button) findViewById(R.id.Button05); button4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { TextView texty; texty = (TextView) findViewById(R.id.texty1); texty.setText("Your BAC is " + Global.Bac ); } }); It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes. Can anyone help me?? The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings. I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work. Any other ways of doing it are very much welcomed!

  • Java textfile I/O problem

    - by KáGé
    Hello, I have to make a torpedo game for school with a toplist for it. I want to store it in a folder structure near the JAR: /Torpedo/local/toplist/top_i.dat, where the i is the place of that score. The files will be created at the first start of the program with this call: File f; f = new File(Toplist.toplistPath+"/top_1.dat"); if(!f.exists()){ Toplist.makeToplist(); } Here is the toplist class: package main; import java.awt.Color; import java.io.BufferedReader; import java.io.File; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.prefs.Preferences; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JTextArea; public class Toplist { static String toplistPath = "./Torpedo/local/toplist"; //I know it won't work this easily, it's only to get you the idea public static JFrame toplistWindow = new JFrame("Torpedó - [TOPLISTA]"); public static JTextArea toplist = new JTextArea(""); static StringBuffer toplistData = new StringBuffer(3000); public Toplist() { toplistWindow.setSize(500, 400); toplistWindow.setLocationRelativeTo(null); toplistWindow.setResizable(false); getToplist(); toplist.setSize(400, 400); toplist.setLocation(0, 100); toplist.setColumns(5); toplist.setText(toplistData.toString()); toplist.setEditable(false); toplist.setBackground(Color.WHITE); toplistWindow.setLayout(null); toplistWindow.setVisible(true); } public Toplist(Player winner) { //this is to be done yet, this will set the toplist at first and then display it toplistWindow.setLayout(null); toplistWindow.setVisible(true); } /** * Creates a new toplist */ public static void makeToplist(){ new File(toplistPath).mkdir(); for(int i = 1; i <= 10; i++){ File f = new File(toplistPath+"/top_"+i+".dat"); try { f.createNewFile(); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista létrehozása", "Error", JOptionPane.ERROR_MESSAGE); } } } /** * If the score is a top score it inserts it into the list * * @param score - the score to be checked */ public static void setToplist(int score, Player winner){ BufferedReader input = null; PrintWriter output = null; int topscore; for(int i = 1; i <= 10; i++){ try { input = new BufferedReader(new FileReader(toplistPath+"/top_"+i+",dat")); String s; topscore = Integer.parseInt(input.readLine()); if(score > topscore){ for(int j = 9; j >= i; j--){ input = new BufferedReader(new FileReader(toplistPath+"/top_"+j+".dat")); output = new PrintWriter(new FileWriter(toplistPath+"/top_"+(j+1)+".dat")); while ((s = input.readLine()) != null) { output.println(s); } } output = new PrintWriter(new FileWriter(toplistPath+"/top_"+i+".dat")); output.println(score); output.println(winner.name); if(winner.isLocal){ output.println(Torpedo.session.remote.name); }else{ output.println(Torpedo.session.remote.name); } output.println(Torpedo.session.mapName); output.println(DateUtils.now()); break; } } catch (FileNotFoundException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } finally { if (input != null) { try { input.close(); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } } if (output != null) { output.close(); } } } } /** * This loads the toplist into the buffer */ public static void getToplist(){ BufferedReader input = null; toplistData = null; String s; for(int i = 1; i <= 10; i++){ try { input = new BufferedReader(new FileReader(toplistPath+"/top_"+i+".dat")); while((s = input.readLine()) != null){ toplistData.append(s); toplistData.append('\t'); } toplistData.append('\n'); } catch (FileNotFoundException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista betöltése", "Error", JOptionPane.ERROR_MESSAGE); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista betöltése", "Error", JOptionPane.ERROR_MESSAGE); } } } /** * * @author http://www.rgagnon.com/javadetails/java-0106.html * */ public static class DateUtils { public static final String DATE_FORMAT_NOW = "yyyy-MM-dd HH:mm:ss"; public static String now() { Calendar cal = Calendar.getInstance(); SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_NOW); return sdf.format(cal.getTime()); } } } The problem is, that it can't access any of the files. I've tried adding them to the classpath and at least six different variations of file/path handling I found online but nothing worked. Could anyone tell me what do I do wrong? Thank you.

  • Using only alphanumeric characters(a-z) inside toCharArray

    - by Aaron
    Below you will find me using toCharArray in order to send a string to array. I then MOVE the value of the letter using a for statement... for(i = 0; i < letter.length; i++){ letter[i] += (shiftCode); System.out.print(letter[i]); } However, when I use shiftCode to move the value such as... a shifted by -1; I get a symbol @. Is there a way to send the string to shiftCode or tell shiftCode to ONLY use letters? I need it to see my text, like "aaron", and when I use the for statement iterate through a-z only and ignore all symbols and numbers. I THINK it is as simple as... letter=codeWord.toCharArray(a,z); But trying different forms of that and googling it didn't give me any results. Perhaps it has to do with regex or something? Below you will find a complete copy of my program; it works exactly how I want it to do; but it iterates through letters and symbols. I also tried finding instructions online for toCharArray but if there exists any arguments I can't locate them.

  • How to get predecessor and successors from an adjacency matrix

    - by NickTFried
    Hi I am am trying to complete an assignment, where it is ok to consult the online community. I have to create a graph class that ultimately can do Breadth First Search and Depth First Search. I have been able to implement those algorithms successfully however another requirement is to be able to get the successors and predecessors and detect if two vertices are either predecessors or successors for each other. I'm having trouble thinking of a way to do this. I will post my code below, if anyone has any suggestions it would be greatly appreciated. import java.util.ArrayList; import java.util.Iterator; import java.util.LinkedList; import java.util.Queue; import java.util.Stack; public class Graph<T> { public Vertex<T> root; public ArrayList<Vertex<T>> vertices=new ArrayList<Vertex<T>>(); public int[][] adjMatrix; int size; private ArrayList<Vertex<T>> dfsArrList; private ArrayList<Vertex<T>> bfsArrList; public void setRootVertex(Vertex<T> n) { this.root=n; } public Vertex<T> getRootVertex() { return this.root; } public void addVertex(Vertex<T> n) { vertices.add(n); } public void removeVertex(int loc){ vertices.remove(loc); } public void addEdge(Vertex<T> start,Vertex<T> end) { if(adjMatrix==null) { size=vertices.size(); adjMatrix=new int[size][size]; } int startIndex=vertices.indexOf(start); int endIndex=vertices.indexOf(end); adjMatrix[startIndex][endIndex]=1; adjMatrix[endIndex][startIndex]=1; } public void removeEdge(Vertex<T> v1, Vertex<T> v2){ int startIndex=vertices.indexOf(v1); int endIndex=vertices.indexOf(v2); adjMatrix[startIndex][endIndex]=1; adjMatrix[endIndex][startIndex]=1; } public int countVertices(){ int ver = vertices.size(); return ver; } /* public boolean isPredecessor( Vertex<T> a, Vertex<T> b){ for() return true; }*/ /* public boolean isSuccessor( Vertex<T> a, Vertex<T> b){ for() return true; }*/ public void getSuccessors(Vertex<T> v1){ } public void getPredessors(Vertex<T> v1){ } private Vertex<T> getUnvisitedChildNode(Vertex<T> n) { int index=vertices.indexOf(n); int j=0; while(j<size) { if(adjMatrix[index][j]==1 && vertices.get(j).visited==false) { return vertices.get(j); } j++; } return null; } public Iterator<Vertex<T>> bfs() { Queue<Vertex<T>> q=new LinkedList<Vertex<T>>(); q.add(this.root); printVertex(this.root); root.visited=true; while(!q.isEmpty()) { Vertex<T> n=q.remove(); Vertex<T> child=null; while((child=getUnvisitedChildNode(n))!=null) { child.visited=true; bfsArrList.add(child); q.add(child); } } clearVertices(); return bfsArrList.iterator(); } public Iterator<Vertex<T>> dfs() { Stack<Vertex<T>> s=new Stack<Vertex<T>>(); s.push(this.root); root.visited=true; printVertex(root); while(!s.isEmpty()) { Vertex<T> n=s.peek(); Vertex<T> child=getUnvisitedChildNode(n); if(child!=null) { child.visited=true; dfsArrList.add(child); s.push(child); } else { s.pop(); } } clearVertices(); return dfsArrList.iterator(); } private void clearVertices() { int i=0; while(i<size) { Vertex<T> n=vertices.get(i); n.visited=false; i++; } } private void printVertex(Vertex<T> n) { System.out.print(n.label+" "); } }

  • What's a reliable and practical way to protect software with a user license ?

    - by Frank
    I know software companies use licenses to protect their softwares, but I also know there are keygen programs to bypass them. I'm a Java developer, if I put my program online for sale, what's a reliable and practical way to protect it ? How about something like this, would it work ? <1> I use ProGuard to protect the source code. <2> Sign the executable Jar file. <3> Since my Java program only need to work on PC [I need to use JDIC in it], I wrap the final executable Jar into an .exe file which makes it harder to decompile. <4> When a user first downloads and runs my app, it checks for a Pass file on his PC. <5> If the Pass file doesn't exist, run the app in demo mode, exits in 5 minutes. <6> When demo exits a panel opens with a "Buy Now" button. This demo mode repeats forever unless step <7> happens. <7> If user clicks the "Buy Now" button, he fills out a detailed form [name, phone, email ...], presses a "Verify Info" button to save the form to a Pass file, leaving license Key # field empty in this newly generated Pass file. <8> Pressing "Verify Info" button will take him to a html form pre-filled with his info to verify what he is buying, also hidden in the form's input filed is a license Key number. He can now press a "Pay Now" button to goto Paypal to finish the process. <9> The hidden license Key # will be passed to Paypal as product Id info and emailed to me. <10> After I got the payment and Paypal email, I'll add the license Key # to a valid license Key list, and put it on my site, only I know the url. The list is updated hourly. <11> Few hours later when the user runs the app again, it can find the Pass file on his PC, but the license Key # value is empty, so it goes to the valid list url to see if its license Key # is on the list, if so, write the license Key # into the Pass file, and the next time it starts again, it will find the valid license Key # and start in purchased mode without exiting in 5 minutes. <12> If it can't find its license Key # on the list from my url, run in demo mode. <13> In order to prevent a user from copying and using another paid user's valid Pass file, the license Key # is unique to each PC [I'm trying to find how], so a valid Pass file only works on one PC. Only after a user has paid will Paypal email me the valid license Key # with his payment. <14> The Id checking goes like this : Use the CPU ID : "CPU_01-02-ABC" for example, encrypt it to the result ID : "XeR5TY67rgf", and compare it to the list on my url, if "XeR5TY67rgf" is not on my valid user list, run in demo mode. If it exists write "XeR5TY67rgf" into the Pass File license field. In order to get a unique license Key, can I use his PC's CPU Id ? Or something unique and useful [ relatively less likely to change ]. If so let's say this CPU ID is "CPU_01-02-ABC", I can encrypt it to something like "XeR5TY67rgf", and pass it to Paypal as product Id in the hidden html form field, then I'll get it from Paypal's email notification, and add it to the valid license Key # list on the url. So, even if a hacker knows it uses CPU Id, he can't write it into the Pass file field, because only encrypted Ids are valid Ids. And only my program knows how to generate the encrypted Ids. And even if another hacker knows the encrypted Id is hidden in the html form input field, as long as it's not on my url list, it's still invalid. Can anyone find any flaw in the above system ? Is it practical ? And most importantly how do I get hold of this unique ID that can represent a user's PC ? Frank

  • What is stopping data flow with .NET 3.5 asynchronous System.Net.Sockets.Socket?

    - by TonyG
    I have a .NET 3.5 client/server socket interface using the asynchronous methods. The client connects to the server and the connection should remain open until the app terminates. The protocol consists of the following pattern: send stx receive ack send data1 receive ack send data2 (repeat 5-6 while more data) receive ack send etx So a single transaction with two datablocks as above would consist of 4 sends from the client. After sending etx the client simply waits for more data to send out, then begins the next transmission with stx. I do not want to break the connection between individual exchanges or after each stx/data/etx payload. Right now, after connection, the client can send the first stx, and get a single ack, but I can't put more data onto the wire after that. Neither side disconnects, the socket is still intact. The client code is seriously abbreviated as follows - I'm following the pattern commonly available in online code samples. private void SendReceive(string data) { // ... SocketAsyncEventArgs completeArgs; completeArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnSend); clientSocket.SendAsync(completeArgs); // two AutoResetEvents, one for send, one for receive if ( !AutoResetEvent.WaitAll(autoSendReceiveEvents , -1) ) Log("failed"); else Log("success"); // ... } private void OnSend( object sender , SocketAsyncEventArgs e ) { // ... Socket s = e.UserToken as Socket; byte[] receiveBuffer = new byte[ 4096 ]; e.SetBuffer(receiveBuffer , 0 , receiveBuffer.Length); e.Completed += new EventHandler<SocketAsyncEventArgs>(OnReceive); s.ReceiveAsync(e); // ... } private void OnReceive( object sender , SocketAsyncEventArgs e ) {} // ... if ( e.BytesTransferred > 0 ) { Int32 bytesTransferred = e.BytesTransferred; String received = Encoding.ASCII.GetString(e.Buffer , e.Offset , bytesTransferred); dataReceived += received; } autoSendReceiveEvents[ SendOperation ].Set(); // could be moved elsewhere autoSendReceiveEvents[ ReceiveOperation ].Set(); // releases mutexes } The code on the server is very similar except that it receives first and then sends a response - the server is not doing anything (that I can tell) to modify the connection after it sends a response. The problem is that the second time I hit SendReceive in the client, the connection is already in a weird state. Do I need to do something in the client to preserve the SocketAsyncEventArgs, and re-use the same object for the lifetime of the socket/connection? I'm not sure which eventargs object should hang around during the life of the connection or a given exchange. Do I need to do something, or Not do something in the server to ensure it continues to Receive data? The server setup and response processing looks like this: void Start() { // ... listenSocket.Bind(...); listenSocket.Listen(0); StartAccept(null); // note accept as soon as we start. OK? mutex.WaitOne(); } void StartAccept(SocketAsyncEventArgs acceptEventArg) { if ( acceptEventArg == null ) { acceptEventArg = new SocketAsyncEventArgs(); acceptEventArg.Completed += new EventHandler<SocketAsyncEventArgs>(OnAcceptCompleted); } Boolean willRaiseEvent = this.listenSocket.AcceptAsync(acceptEventArg); if ( !willRaiseEvent ) ProcessAccept(acceptEventArg); // ... } private void OnAcceptCompleted( object sender , SocketAsyncEventArgs e ) { ProcessAccept(e); } private void ProcessAccept( SocketAsyncEventArgs e ) { // ... SocketAsyncEventArgs readEventArgs = new SocketAsyncEventArgs(); readEventArgs.SetBuffer(dataBuffer , 0 , Int16.MaxValue); readEventArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnIOCompleted); readEventArgs.UserToken = e.AcceptSocket; dataReceived = ""; // note server is degraded for single client/thread use // As soon as the client is connected, post a receive to the connection. Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs); if ( !willRaiseEvent ) this.ProcessReceive(readEventArgs); // Accept the next connection request. this.StartAccept(e); } private void OnIOCompleted( object sender , SocketAsyncEventArgs e ) { // switch ( e.LastOperation ) case SocketAsyncOperation.Receive: ProcessReceive(e); // similar to client code // operate on dataReceived here case SocketAsyncOperation.Send: ProcessSend(e); // similar to client code } // execute this when a data has been processed into a response (ack, etc) private SendResponseToClient(string response) { // create buffer with response // currentEventArgs has class scope and is re-used currentEventArgs.SetBuffer(sendBuffer , 0 , sendBuffer.Length); Boolean willRaiseEvent = currentClient.SendAsync(currentEventArgs); if ( !willRaiseEvent ) ProcessSend(currentEventArgs); } A .NET trace shows the following when sending ABC\r\n: Socket#7588182::SendAsync() Socket#7588182::SendAsync(True#1) Data from Socket#7588182::FinishOperation(SendAsync) 00000000 : 41 42 43 0D 0A Socket#7588182::ReceiveAsync() Exiting Socket#7588182::ReceiveAsync() - True#1 And it stops there. It looks just like the first send from the client but the server shows no activity. I think that could be info overload for now but I'll be happy to provide more details as required. Thanks!

  • Zend_Form validation problem

    - by GrumpyCanuck
    I am having problems getting validation to work for a form built using Zend_Form. The idea is this: I have two dropdown. One is a list of players. The other is a list of free agents who play the same position as the player. I am using an onChange javascript callback to run some Ajax code that replaces the free agent list dropdown with a new one at the position of the player they've selected from the player dropdown. Now, perhaps this is the wrong way, but I built the form by creating an instance of Zend_Form and then creating all these setX methods that add elements to the form. My reasoning was that I wanted to display certain elements in specific places on the page, not just output $this-form on my template. The problem appears to be when I get the form post back, the validator seems to not know about the validation rule I set up for the free agent drop down. Here's some relevant code to look at. I'm a relative ZF n00b so feel free to tell me I am not doing things the ZF way if it leaps out at you. The action in the controller: public function indexAction() { if ($this->getRequest()->isPost()) { $form = new Baseball_Form_Transactions(); if ($form->isValid($this->_request->getPost())) { $data = $this->_request->getPost(); $leagueInfo = Doctrine::getTable('League')->findOneByShortName($data['shortLeagueName'])->toArray(); // Create the request top drop an existing player $transactionInfo = array( 'league_id' => $leagueInfo['id'], 'team_id' => $data['teamId'], 'player_id' => $data['players'], 'type' => 'drop', 'target_team_id' => 0, 'transaction_date' => date('Y-m-d H:m:s') ); $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); // Now we do the request to add a player $transactionInfo['team_id'] = 0; $transactionInfo['player_id'] = $data['freeAgents']; $transactionInfo['target_team_id'] = $data['teamId']; $transactionInfo['type'] = 'add'; $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); $this->_flashMessenger->addMessage('Added transaction'); } } $options = array( 'teamId' => $this->teamId, 'position' => 'C', 'leagueShortName' => $this->league ); $this->transactionForm->setMyPlayers($options); $this->transactionForm->setFreeAgents($options); $this->transactionForm->setTeamId($options); $this->transactionForm->setShortLeagueName($options); $this->view->transactionForm = $this->transactionForm; $this->view->messages = $this->_flashMessenger->getMessages(); $transaction = new Transaction(); $this->view->transactions = $transaction->byTeam($options); } Next we have the form itself public function setMyPlayers($options) { $data = Doctrine::getTable('Team')->find($options['teamId']); $players = array(); foreach ($data->Players->toArray() as $player) { $players[$player['id']] = "{$player['position']} - {$player['first_name']} {$player['last_name']}"; } $playersSelect = new Zend_Form_Element_Select( 'players', array( 'required' => true, 'label' => 'Players', 'multiOptions' => $players, ) ); $this->addElement($playersSelect); } public function setFreeAgents($options) { $q = Doctrine_Query::create() ->select('CONCAT(p.first_name, " ", p.last_name) as full_name, p.id, p.position') ->from('Player p') ->leftJoin('p.Teams t') ->leftJoin('t.League l ON l.short_name = ?', $options['leagueShortName']) ->where('t.id IS NULL') ->andWhere('p.position = ?', $options['position']) ->orderBy('p.last_name'); $q->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $data = $q->execute(); $freeAgents = array(); foreach ($data as $player) { $freeAgents[$player['id']] = $player['full_name']; } $freeAgentsSelect = new Zend_Form_Element_Select( 'freeAgents', array( 'label' => 'Free Agents', 'multiOptions' => $freeAgents, 'size' => 15 ) ); $freeAgentsSelect->setRequired(true); $this->addElement($freeAgentsSelect); } public function setShortLeagueName($options) { $shortLeagueNameHidden = new Zend_Form_Element_Hidden( 'shortLeagueName', array('value' => $options['leagueShortName']) ); $this->addElement($shortLeagueNameHidden); } public function setTeamId($options) { $teamIdHidden = new Zend_Form_Element_Hidden( 'teamId', array('value' => $options['teamId']) ); $this->addElement($teamIdHidden); } There is no init or __construct() method in the form. My problem seems simple enough: reject the form contents as invalid if they have not selected someone from the free agent list. Right now, it sails through as valid. I've spent some considerable time searching online for an answer, and haven't been able to find it. Thanks in advance for any help.

However each time I try it, it crashes the hack and says I had a access violation. I tried to look up the reasons and most of them dealt with with the size of the location I'm writing to and what I'm copying from. Otherwise, I have absolutely no idea. Any help would be nice. The game is GunRoar and the base address "0x409A7E" is where the DEC function is.

  • ArrayList access

    - by Ricky McQuesten
    So once again I have a question about this program. I want to store transactions that are made in an arraylist and then have an option in the case menu where I can print out those that are stored. I have been researching online and have been unable to find a solution to this, so is this possible and how would I go about doing this? I also want to attach a timestamp to each transaction as well. Here is the code I have so far. So my question is how would I add a timestamp to each withdrawal or deposit, and how would I store each transaction in array list? import java.util.*; public class BankAccount extends Money { //inheritence static String name; public static int acctNum; public static double balance, amount; BankAccount(String name, int accNo, double bal) { this.name = name; this.acctNum = accNo; this.balance = bal; } void display() { System.out.println("Your Name:" + name); System.out.println("Your Account Number:" + acctNum); System.out.println("Your Current Account Balance:" + Money.getBalance()); } void displayBalance() { System.out.println("Balance:" + balance); } } import java.util.Scanner; /** * * @author Ricky */ public class Money { public static int accountNumber; public static double balance; static double amount; static String name; public void setDeposit(double amount) { balance = balance + amount; if (amount < 0) { System.out.println("Invalid"); } } public double getDeposit() { return 1; } public void setBalance(double b) { balance = b; } public static double getBalance() { return balance; } public void setWithdraw(double amount) { if (balance < amount) { System.out.println("Not enough funds."); } else if(amount < 0) { System.out.println("Invalid"); } else { balance = balance - amount; } } public double getWithdraw() { return 1; } } import java.util.*; public class Client { public static void main(String args[]) { int n = 0; int count; String trans; ArrayList<String> transaction= new ArrayList<String>(n); Scanner input = new Scanner(System.in); System.out.println("Welcome to First National Bank"); System.out.println("Please enter your name: "); String cusName = input.nextLine(); System.out.println("You will now be assigned an account number."); Random randomGenerator = new Random(); int accNo = randomGenerator.nextInt(100000); //random number System.out.println("Your account number is: " + accNo); System.out.println("Please enter your initial account balance: "); Double balance = input.nextDouble(); BankAccount b1 = new BankAccount(cusName, accNo, balance); b1.setBalance(balance); int menu; /*System.out.println("Menu"); System.out.println("1.

  • Ado.Net Entity produces "namespace cannot be found"

    - by Dave
    I've seen several possible solutions to this, but none have worked for me. After adding a ADO.NET Entity Data Model to my .Net Forms C# web project, I am unable to use it. Perhaps I made a mistake adding it? The name of the file added is QcFormData.edmx. In my code, perhaps I'm instantiating it incorrectly? I tried adding the line: QcFormDataContainer db = new QcFormDataContainer(); It appears in Intellisense, but when compiling I get the error : Error 13 The type or namespace name 'QcFormDataContainer' could not be found (are you missing a using directive or an assembly reference?) I've followed the suggestions that I found online that did not help: 1) made sure there is "using System.Data.Entity" 2) made sure the dll exists. 3) made sure the reference exists. 4) one post said use using System.Web.Data.Entity; but I do not see that available. What am I missing?

  • jQuery works in FF but not in Safari

    - by Hristo
    I have some event handlers that work in FF and not in Safari. Simply put, I have a list of friends, some hard-coded, some pulled in from a database. Clicking on a buddy opens a chat window... this is much like the Facebook chat system. So in Firefox, everything works normally and as expected. In Safari, clicking on buddies that are hard-coded works fine, but clicking on buddies that are pulled in from the database doesn't pull up the chat window. <script type="text/javascript" src="js/jQuery.js"></script> <script type="text/javascript" src="js/chat.js"></script> <script type="text/javascript" src="js/ChatBar.js"></script> <script type="text/javascript" src="js/settings.js"></script> <script type="text/javascript"> var chat = new Chat(); var from = <?php echo "'" .$_SESSION['userid'] . "'"; ?>; chat.getUsers(<?php echo "'" .$_SESSION['userid'] . "'"; ?>); </script> So I load all my buddies with chat.getUsers. That function is: // get list of friends function getBuddyList(userName) { userNameID = userName; $.ajax({ type: "GET", url: "buddyList.php", data: { 'userName': userName, 'current': numOfUsers }, dataType: "json", cache: false, success: function(data) { if (numOfUsers != data.numOfUsers) { numOfUsers = data.numOfUsers; var list = "<li><span>Agents</span></li>"; for (var i = 0; i < data.friendlist.length; i++) { list += "<li><a class=\"buddy\" href=\"#\"><img alt=\"\" src=\"images/chat-thumb.gif\">"+ data.friendlist[i] +"</a></li>"; } $('#friend-list ul').append($(list)); } setTimeout('getBuddyList(userNameID)', 1000); } }); } buddyList.php just pulls in the Users from the database and returns an array with the user names. So the jQuery for clicking a buddy is: // click on buddy in #friends-panel $('#friends-panel a.buddy').click(function() { alert("Loaded"); // close #friends-panel $('.subpanel').hide(); $('#friends-panel a.chat').removeClass('active'); // if a chat window is already active, close it and deactivate $('#mainpanel li[class="active-buddy-tab"] div').not('#chat-box').removeAttr('id'); $('#mainpanel li[class="active-buddy-tab"]').removeClass('active-buddy-tab').addClass('buddy-tab'); // create active buddy chat window $('#mainpanel').append('<li class="active-buddy-tab"><a class="buddy-tab" href="#"></a><div id="chat-window"><h3><p id="to"></p></h3></div></li>'); // create name and close/minimize buttons $('.active-buddy-tab div h3 p#to').text($(this).text()); $('.active-buddy-tab div h3').append('<span class="close"> X </span><span class="minimize"> &ndash; </span>'); $('.active-buddy-tab').append('<span class="close"> X </span>'); // create chat area $('.active-buddy-tab div').append('<div id="chat-box"></div><form id="chat-message"><textarea id="message" maxlength="100"></textarea></form>'); // put curser in chat window $('.active-buddy-tab #message').focus(); // create a chat relationship return false; }); ... and the basic structure of the HTML is: <div id="footpanel"> <ul id="mainpanel"> <li id="friends-panel"> <a href="#" class="chat">Friends (<strong>18</strong>) </a> <div id="friend-list" class="subpanel"> <h3><span> &ndash; </span>Friends Online</h3> <ul> <li><span>Family Members</span></li> <!-- Hard coded buddies --> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend 1</a></li> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend </a></li> <!-- buddies will be added in dynamically here --> </ul> </div> </li> </ul> </div> I'm not too sure where to begin solving this issue. I thought it might be a rendering bug or something with the DOM but I've been staring at this code all day and I'm stuck. Any ideas on why it works in FF and not in Safari? btw... I'm testing on Snow Leopard. Thanks, Hristo

  • What is the MVC version of this code?

    - by Ian Boyd
    i'm trying to wrap my head around how to enterprise up my code: taking a simple routine and splitting it up into 5 or 6 methods in 3 or 4 classes. i quickly came up three simple examples of code how i currently write it. Could someone please convert these into an MVC/MVP obfuscated version? Example 1: The last name is mandatory. Color the text box red if nothing is entered. Color it green if stuff is entered: private void txtLastname_TextChanged(object sender, EventArgs e) { //Lastname mandatory. //Color pinkish if nothing entered. Greenish if entered. if (txtLastname.Text.Trim() == "") { //Lastname is required, color pinkish txtLastname.BackColor = ControlBad; } else { //Lastname entered, remove the coloring txtLastname.BackColor = ControlGood; } } Example 2: The first name is optional, but try to get it. We'll add a bluish tint to this "try to get" field: private void txtFirstname_TextChanged(object sender, EventArgs e) { //Firstname can be blank. //Hint them that they should *try* to get it with a bluish color. //If they do enter stuff: it better be not all spaces. if (txtFirstname.Text == "") { //Nothing there, hint it blue txtFirstname.BackColor = ControlRequired; } else if (txtFirstname.Text.Trim() == "") { //They entered spaces - bad user! txtFirstname.BackColor = ControlBad; } else { //Entered stuff, remove coloring txtFirstname.BackColor = SystemColors.Window; } } Example 3 The age is totally optional. If an age is entered, it better be valid: private void txtAge_TextChanged(object sender, EventArgs e) { //Age is optional, but if entered it better be valid int nAge = 0; if (Int32.TryParse(txtAge.Text, out nAge)) { //Valid integer entered if (nAge < 0) { //Negative age? i don't think so txtAge.BackColor = ControlBad; } else { //Valid age entered, remove coloring txtAge.BackColor = SystemColors.Window; } } else { //Whatever is in there: it's *not* a valid integer, if (txtAge.Text == "") { //Blank is okay txtAge.BackColor = SystemColors.Window; } else { //Not a valid age, bad user txtAge.BackColor = ControlBad; } } } Every time i see MVC code, it looks almost like random splitting of code into different methods, classes, and files. i've not been able to determine a reason or pattern to their madness. Without any understanding of they why it's being one some way, it makes no sense. And using the words model, view, controller and presenter, like i'm supposed to know what that means, doesn't help. The model is your data. The view shows data on screen. The controller is used to carry out the users actions And oranges taste orangy. Here's my attempt at splitting things up in order to make the code more difficult to follow. Is this anywhere close to MVC? private void txtFirstname_TextChanged(object sender, EventArgs e) { FirstnameTextChangedHandler(sender, e); } private void FirstnameTextChangedHandler(sender, e) { string firstname = GetFirstname(); Color firstnameTextBoxColor = GetFirstnameTextBoxColor(firstname); SetFirstNameTextBoxColor(firstnameTextBoxColor); } private string GetFirstname() { return txtFirstname.Text; } private Color GetFirstnameTextBoxColor(string firstname) { //Firstname can be blank. //Hint them that they should *try* to get it with a bluish color. //If they do enter stuff: it better be not all spaces. if (firstname == "") { //Nothing there, hint it blue return GetControlRequiredColor(); } else if (firstname.Trim() == "") { //They entered spaces - bad user! return GetControlBadColor(); } else { //Entered stuff, remove coloring return GetControlDefaultColor(); } } private Color GetControlRequiredColor() { return ControlRequired; } private Color GetControlBadColor() { return ControlBad; } private Color GetControlGoodColor() { return ControlGood; } //am i doin it rite i've obfuscated the code, but it's still altogether. The next step in the MVC obfuscation, i gather, is to hide the code in 3 or 4 different files. It's that next step that i don't understand. What is the logical separation of which functions are moved into what other classes? Can someone translate my 3 simple examples above into full fledged MVC obfuscation? Edit: Not ASP/ASP.NET/Online. Pretend it's on a desktop, handheld, surface, kiosk. And pretend it's language agnostic.

  • JQuery Dynamic Element - In DOM but unable to bind

    - by Grant80
    Hi All, I'm new to using JQuery so bear with me. I had implmented some code based on a js file that I found online which enables a series of div tags within a nested structure on my page to step through and show each one individually on the page. This all works great when I define the div tags as static entries in the masterpage. I should add that this is being implemented in a SharePoint master page. Ultimately though, with a static collection of div tags ideally containing an image with some descriptive text, and a hyperlink its not very flexible. Roll on my changes to make this a little more configurable. I have implemented some additional code that will read from a SharePoint list via an ajax call to the lists web service. For each entry in the list I am building a div tag that contains the information required dynamically. For testing, I am only pulling the title through at present. I have used the following code: $('#beltDiv').append(divHTML) to append the divs in the loop that are created to my nested structure on the page. I figured that this would cause the fade code to work as expected but I was wrong. It doesn't do anything at all. When check the source on the page, the div tags are not shown. They are however available in the DOM model when viewed through the IE developer toolbar. The issue (I think) looks to be that the initiation of the featureFade code is not working due to the div tags being unavailable. Is there a way to address this? The code used is shown below: <script type="text/javascript"> $(document).ready(function() { var soapEnv = "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'> \ <soapenv:Body> \ <GetListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \ <listName>Carousel Items</listName> \ <viewFields> \ <ViewFields> \ <FieldRef Name='Title' /> \ </ViewFields> \ </viewFields> \ </GetListItems> \ </soapenv:Body> \ </soapenv:Envelope>"; $.ajax({ url: "_vti_bin/lists.asmx", type: "POST", dataType: "xml", data: soapEnv, complete: processResult, contentType: "text/xml; charset=\"utf-8\"" }); }); function processResult(xData, status) { $(xData.responseXML).find("z\\:row").each(function() { var divHTML = "<div id=\"divPanel_" + $(this).attr("ows_Title") + "\" class=\"panel\" style=\"background:url('http://devSP2010/sites/SPSOPS/Style Library/SharePointOps/Images/01.jpg') no-repeat; width:650px; height:55px;\"><div><div class=\"content\"><div><P><A style=\"COLOR: #cc0000\" href=\"www.google.com\">" + $(this).attr("ows_Title") + "</A></P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P></div></div></div></div>"; $("#beltDiv").append(divHTML); }); } featureFade.setup({ galleryid: 'headlines', beltclass: 'belt', panelclass: 'panel', autostep: { enable: true, moveby: 1, pause: 10000 }, panelbehavior: { speed: 1000, wraparound: true }, stepImgIDs: ["ftOne", "ftTwo", "ftThree", "ftFour","ftFive"], defaultButtons: { itemOn: "Style Library/SharePointOps/Images/dotOn.png", itemOff: "Style Library/SharePointOps/Images/dotOff.png" } }); The section where the div tags are dynamically appended is shown below. I've commented out the static div tags that work as expected. The only change is that these are implmented by the JQuery logic: <div class="homeFeature" style="display:inline-block"> <div id="headlines" class="headlines"> <div id="beltDiv" class="belt"> <!-- <div id="divPanel_ct01" class="panel" style="position:absolute;background-image:url('http://devsp2010/sites/spsops/Style Library/SharePointOps/Images/01.jpg'); background-repeat:no-repeat">Static Test 1</div> <div id="divPanel_ct02" class="panel" style="position:absolute;background-image:url('http://devsp2010/sites/spsops/Style Library/SharePointOps/Images/02.jpg'); background-repeat:no-repeat">Static Test 2</div> --> </div> </div> I'm stumped as to why it's not recognising the dynamically added elements in the DOM. Any help would be greatly appreciated on this. I'm happy to provide any further information on this. Thanks in advance, Grant Further to the answer recieved: I have modified the function call: function processResult(xData, status) { $(xData.responseXML).find("z\\:row").each( function() { /*alert($(this).attr("ows_ImagePath"));*/ var divHTML = "<div id=\"divPanel_" + $(this).attr("ows_Title") + "\" class=\"panel\" style=\"background:url('http://devSP2010/sites/SPSOPS/Style Library/SharePointOps/Images/ClydePort01big.jpg') no-repeat; width:650px; height:55px;\"><div><div class=\"content\"><div><P><A style=\"COLOR: #cc0000\" href=\"www.google.com\">" + $(this).attr("ows_Title") + "</A></P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P></div></div></div></div>"; $("#beltDiv").append(divHTML); } ); featureFade.setup( { galleryid: 'headlines', beltclass: 'belt', panelclass: 'panel', autostep: { enable: true, moveby: 1, pause: 10000 }, panelbehavior: { speed: 1000, wraparound: true }, stepImgIDs: ["ftOne", "ftTwo", "ftThree", "ftFour","ftFive"], defaultButtons: { itemOn: "Style Library/SharePointOps/Images/dotOn.png", itemOff: "Style Library/SharePointOps/Images/dotOff.png" } } ); }

  • Play 2.0 javaToDo tutorial doesn't compile

    - by chsn
    I'm trying to follow the Play2.0 JavaToDO tutorial and for some reason it just doesn't want to work. Have looked through stackoverflow and other online resources, but haven't find an answer to this and it's driving me crazy. Attached code of the Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { static Form<Task> taskForm = form(Task.class); public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result newTask() { return TODO; } public static Result deleteTask(Long id) { return TODO; } } Attached code of the Task java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task { public Long id; @Required public String label; // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create task public static void create(Task task) { task.create(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } // create new task public static Result newTask() { Form<Task> filledForm = taskForm.bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.create(filledForm.get()); return redirect(routes.Application.tasks()); } } } I get a compile error on Task.java on the line static Form<Task> taskForm = form(Task.class); As I'm working on eclipse (the project is eclipsified before import), it's telling me that taskForm cannot be resolved and it also underlines every play 2 command e.g. "render(), redirect(), bindFromRequest()" asking me to create a method for it. Any ideas how to solve the compilations error and also how to get Eclipse to recognize the play2 commands? EDIT: updated Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { // create new task public static Result newTask() { Form<Task> filledForm = form(Task.class).bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.newTask(filledForm.get()); return redirect(routes.Application.tasks()); } } public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result deleteTask(Long id) { return TODO; } } Updated task.java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task extends Model { public Long id; @Required public String label; // Define a taskForm static Form<Task> taskForm = form(Task.class); // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create new task public static Result newTask(Task newTask) { save(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } }

  • bandwidth throttling C linux

    - by bob moch
    hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.

  • Loading jQuery Consistently in a .NET Web App

    - by Rick Strahl
    One thing that frequently comes up in discussions when using jQuery is how to best load the jQuery library (as well as other commonly used and updated libraries) in a Web application. Specifically the issue is the one of versioning and making sure that you can easily update and switch versions of script files with application wide settings in one place and having your script usage reflect those settings in the entire application on all pages that use the script. Although I use jQuery as an example here, the same concepts can be applied to any script library - for example in my Web libraries I use the same approach for jQuery.ui and my own internal jQuery support library. The concepts used here can be applied both in WebForms and MVC. Loading jQuery Properly From CDN Before we look at a generic way to load jQuery via some server logic, let me first point out my preferred way to embed jQuery into the page. I use the Google CDN to load jQuery and then use a fallback URL to handle the offline or no Internet connection scenario. Why use a CDN? CDN links tend to be loaded more quickly since they are very likely to be cached in user's browsers already as jQuery CDN is used by many, many sites on the Web. Using a CDN also removes load from your Web server and puts the load bearing on the CDN provider - in this case Google - rather than on your Web site. On the downside, CDN links gives the provider (Google, Microsoft) yet another way to track users through their Web usage. Here's how I use jQuery CDN plus a fallback link on my WebLog for example: <!DOCTYPE HTML> <html> <head> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script> <script> if (typeof (jQuery) == 'undefined') document.write(unescape("%3Cscript " + "src='/Weblog/wwSC.axd?r=Westwind.Web.Controls.Resources.jquery.js' %3E%3C/script%3E")); </script> <title>Rick Strahl's Web Log</title> ... </head>   You can see that the CDN is referenced first, followed by a small script block that checks to see whether jQuery was loaded (jQuery object exists). If it didn't load another script reference is added to the document dynamically pointing to a backup URL. In this case my backup URL points at a WebResource in my Westwind.Web  assembly, but the URL can also be local script like src="/scripts/jquery.min.js". Important: Use the proper Protocol/Scheme for  for CDN Urls [updated based on comments] If you're using a CDN to load an external script resource you should always make sure that the script is loaded with the same protocol as the parent page to avoid mixed content warnings by the browser. You don't want to load a script link to an http:// resource when you're on an https:// page. The easiest way to use this is by using a protocol relative URL: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script> which is an easy way to load resources from other domains. This URL syntax will automatically use the parent page's protocol (or more correctly scheme). As long as the remote domains support both http:// and https:// access this should work. BTW this also works in CSS (with some limitations) and links. BTW, I didn't know about this until it was pointed out in the comments. This is a very useful feature for many things - ah the benefits of my blog to myself :-) Version Numbers When you use a CDN you notice that you have to reference a specific version of jQuery. When using local files you may not have to do this as you can rename your private copy of jQuery.js, but for CDN the references are always versioned. The version number is of course very important to ensure you getting the version you have tested with, but it's also important to the provider because it ensures that cached content is always correct. If an existing file was updated the updates might take a very long time to get past the locally cached content and won't refresh properly. The version number ensures you get the right version and not some cached content that has been changed but not updated in your cache. On the other hand version numbers also mean that once you decide to use a new version of the script you now have to change all your script references in your pages. Depending on whether you use some sort of master/layout page or not this may or may not be easy in your application. Even if you do use master/layout pages, chances are that you probably have a few of them and at the very least all of those have to be updated for the scripts. If you use individual pages for all content this issue then spreads to all of your pages. Search and Replace in Files will do the trick, but it's still something that's easy to forget and worry about. Personaly I think it makes sense to have a single place where you can specify common script libraries that you want to load and more importantly which versions thereof and where they are loaded from. Loading Scripts via Server Code Script loading has always been important to me and as long as I can remember I've always built some custom script loading routines into my Web frameworks. WebForms makes this fairly easy because it has a reasonably useful script manager (ClientScriptManager and the ScriptManager) which allow injecting script into the page easily from anywhere in the Page cycle. What's nice about these components is that they allow scripts to be injected by controls so components can wrap up complex script/resource dependencies more easily without having to require long lists of CSS/Scripts/Image includes. In MVC or pure script driven applications like Razor WebPages  the process is more raw, requiring you to embed script references in the right place. But its also more immediate - it lets you know exactly which versions of scripts to use because you have to manually embed them. In WebForms with different controls loading resources this often can get confusing because it's quite possible to load multiple versions of the same script library into a page, the results of which are less than optimal… In this post I look a simple routine that embeds jQuery into the page based on a few application wide configuration settings. It returns only a string of the script tags that can be manually embedded into a Page template. It's a small function that merely a string of the script tags shown at the begging of this post along with some options on how that string is comprised. You'll be able to specify in one place which version loads and then all places where the help function is used will automatically reflect this selection. Options allow specification of the jQuery CDN Url, the fallback Url and where jQuery should be loaded from (script folder, Resource or CDN in my case). While this is specific to jQuery you can apply this to other resources as well. For example I use a similar approach with jQuery.ui as well using practically the same semantics. Providing Resources in ControlResources In my Westwind.Web Web utility library I have a class called ControlResources which is responsible for holding resource Urls, resource IDs and string contants that reference those resource IDs. The library also provides a few helper methods for loading common scriptscripts into a Web page. There are specific versions for WebForms which use the ClientScriptManager/ScriptManager and script link methods that can be used in any .NET technology that can embed an expression into the output template (or code for that matter). The ControlResources class contains mostly static content - references to resources mostly. But it also contains a few static properties that configure script loading: A Script LoadMode (CDN, Resource, or script url) A default CDN Url A fallback url They are  static properties in the ControlResources class: public class ControlResources { /// <summary> /// Determines what location jQuery is loaded from /// </summary> public static JQueryLoadModes jQueryLoadMode = JQueryLoadModes.ContentDeliveryNetwork; /// <summary> /// jQuery CDN Url on Google /// </summary> public static string jQueryCdnUrl = "//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"; /// <summary> /// jQuery CDN Url on Google /// </summary> public static string jQueryUiCdnUrl = "//ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"; /// <summary> /// jQuery UI fallback Url if CDN is unavailable or WebResource is used /// Note: The file needs to exist and hold the minimized version of jQuery ui /// </summary> public static string jQueryUiLocalFallbackUrl = "~/scripts/jquery-ui.min.js"; } These static properties are fixed values that can be changed at application startup to reflect your preferences. Since they're static they are application wide settings and respected across the entire Web application running. It's best to set these default in Application_Init or similar startup code if you need to change them for your application: protected void Application_Start(object sender, EventArgs e) { // Force jQuery to be loaded off Google Content Network ControlResources.jQueryLoadMode = JQueryLoadModes.ContentDeliveryNetwork; // Allow overriding of the Cdn url ControlResources.jQueryCdnUrl = "http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"; // Route to our own internal handler App.OnApplicationStart(); } With these basic settings in place you can then embed expressions into a page easily. In WebForms use: <!DOCTYPE html> <html> <head runat="server"> <%= ControlResources.jQueryLink() %> <script src="scripts/ww.jquery.min.js"></script> </head> In Razor use: <!DOCTYPE html> <html> <head> @Html.Raw(ControlResources.jQueryLink()) <script src="scripts/ww.jquery.min.js"></script> </head> Note that in Razor you need to use @Html.Raw() to force the string NOT to escape. Razor by default escapes string results and this ensures that the HTML content is properly expanded as raw HTML text. Both the WebForms and Razor output produce: <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> if (typeof (jQuery) == 'undefined') document.write(unescape("%3Cscript src='/WestWindWebToolkitWeb/WebResource.axd?d=-b6oWzgbpGb8uTaHDrCMv59VSmGhilZP5_T_B8anpGx7X-PmW_1eu1KoHDvox-XHqA1EEb-Tl2YAP3bBeebGN65tv-7-yAimtG4ZnoWH633pExpJor8Qp1aKbk-KQWSoNfRC7rQJHXVP4tC0reYzVw2&t=634535391996872492' type='text/javascript'%3E%3C/script%3E"));</script> <script src="scripts/ww.jquery.min.js"></script> </head> which produces the desired effect for both CDN load and fallback URL. The implementation of jQueryLink is pretty basic of course: /// <summary> /// Inserts a script link to load jQuery into the page based on the jQueryLoadModes settings /// of this class. Default load is by CDN plus WebResource fallback /// </summary> /// <param name="url"> /// An optional explicit URL to load jQuery from. Url is resolved. /// When specified no fallback is applied /// </param> /// <returns>full script tag and fallback script for jQuery to load</returns> public static string jQueryLink(JQueryLoadModes jQueryLoadMode = JQueryLoadModes.Default, string url = null) { string jQueryUrl = string.Empty; string fallbackScript = string.Empty; if (jQueryLoadMode == JQueryLoadModes.Default) jQueryLoadMode = ControlResources.jQueryLoadMode; if (!string.IsNullOrEmpty(url)) jQueryUrl = WebUtils.ResolveUrl(url); else if (jQueryLoadMode == JQueryLoadModes.WebResource) { Page page = new Page(); jQueryUrl = page.ClientScript.GetWebResourceUrl(typeof(ControlResources), ControlResources.JQUERY_SCRIPT_RESOURCE); } else if (jQueryLoadMode == JQueryLoadModes.ContentDeliveryNetwork) { jQueryUrl = ControlResources.jQueryCdnUrl; if (!string.IsNullOrEmpty(jQueryCdnUrl)) { // check if jquery loaded - if it didn't we're not online and use WebResource fallbackScript = @"<script type=""text/javascript"">if (typeof(jQuery) == 'undefined') document.write(unescape(""%3Cscript src='{0}' type='text/javascript'%3E%3C/script%3E""));</script>"; fallbackScript = string.Format(fallbackScript, WebUtils.ResolveUrl(ControlResources.jQueryCdnFallbackUrl)); } } string output = "<script src=\"" + jQueryUrl + "\" type=\"text/javascript\"></script>"; // add in the CDN fallback script code if (!string.IsNullOrEmpty(fallbackScript)) output += "\r\n" + fallbackScript + "\r\n"; return output; } There's one dependency here on WebUtils.ResolveUrl() which resolves Urls without access to a Page/Control (another one of those features that should be in the runtime, not in the WebForms or MVC engine). You can see there's only a little bit of logic in this code that deals with potentially different load modes. I can load scripts from a Url, WebResources or - my preferred way - from CDN. Based on the static settings the scripts to embed are composed to be returned as simple string <script> tag(s). I find this extremely useful especially when I'm not connected to the internet so that I can quickly swap in a local jQuery resource instead of loading from CDN. While CDN loading with the fallback works it can be a bit slow as the CDN is probed first before the fallback kicks in. Switching quickly in one place makes this trivial. It also makes it very easy once a new version of jQuery rolls around to move up to the new version and ensure that all pages are using the new version immediately. I'm not trying to make this out as 'the' definite way to load your resources, but rather provide it here as a pointer so you can maybe apply your own logic to determine where scripts come from and how they load. You could even automate this some more by using configuration settings or reading the locations/preferences out of some sort of data/metadata store that can be dynamically updated instead via recompilation. FWIW, I use a very similar approach for loading jQuery UI and my own ww.jquery library - the same concept can be applied to any kind of script you might be loading from different locations. Hopefully some of you find this a useful addition to your toolset.

  • Integrating HTML into Silverlight Applications

    - by dwahlin
    Looking for a way to display HTML content within a Silverlight application? If you haven’t tried doing that before it can be challenging at first until you know a few tricks of the trade.  Being able to display HTML is especially handy when you’re required to display RSS feeds (with embedded HTML), SQL Server Reporting Services reports, PDF files (not actually HTML – but the techniques discussed will work), or other HTML content.  In this post I'll discuss three options for displaying HTML content in Silverlight applications and describe how my company is using these techniques in client applications. Displaying HTML Overlays If you need to display HTML over a Silverlight application (such as an RSS feed containing HTML data in it) you’ll need to set the Silverlight control’s windowless parameter to true. This can be done using the object tag as shown next: <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/HTMLAndSilverlight.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50401.0" /> <param name="autoUpgrade" value="true" /> <param name="windowless" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50401.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object> By setting the control to “windowless” you can overlay HTML objects by using absolute positioning and other CSS techniques. Keep in mind that on Windows machines the windowless setting can result in a performance hit when complex animations or HD video are running since the plug-in content is displayed directly by the browser window. It goes without saying that you should only set windowless to true when you really need the functionality it offers. For example, if I want to display my blog’s RSS content on top of a Silverlight application I could set windowless to true and create a user control that grabbed the content and output it using a DataList control: <style type="text/css"> a {text-decoration:none;font-weight:bold;font-size:14pt;} </style> <div style="margin-top:10px; margin-left:10px;margin-right:5px;"> <asp:DataList ID="RSSDataList" runat="server" DataSourceID="RSSDataSource"> <ItemTemplate> <a href='<%# XPath("link") %>'><%# XPath("title") %></a> <br /> <%# XPath("description") %> <br /> </ItemTemplate> </asp:DataList> <asp:XmlDataSource ID="RSSDataSource" DataFile="http://weblogs.asp.net/dwahlin/rss.aspx" XPath="rss/channel/item" CacheDuration="60" runat="server" /> </div> The user control can then be placed in the page hosting the Silverlight control as shown below. This example adds a Close button, additional content to display in the overlay window and the HTML generated from the user control. <div id="RSSDiv"> <div style="background-color:#484848;border:1px solid black;height:35px;width:100%;"> <img alt="Close Button" align="right" src="Images/Close.png" onclick="HideOverlay();" style="cursor:pointer;" /> </div> <div style="overflow:auto;width:800px;height:565px;"> <div style="float:left;width:100px;height:103px;margin-left:10px;margin-top:5px;"> <img src="http://weblogs.asp.net/blogs/dwahlin/dan2008.jpg" style="border:1px solid Gray" /> </div> <div style="float:left;width:300px;height:103px;margin-top:5px;"> <a href="http://weblogs.asp.net/dwahlin" style="margin-left:10px;font-size:20pt;">Dan Wahlin's Blog</a> </div> <br /><br /><br /> <div style="clear:both;margin-top:20px;"> <uc:BlogRoller ID="BlogRoller" runat="server" /> </div> </div> </div> Of course, we wouldn’t want the RSS HTML content to be shown until requested. Once it’s requested the absolute position of where it should show above the Silverlight control can be set using standard CSS styles. The following ID selector named #RSSDiv handles hiding the overlay div shown above and determines where it will be display on the screen. #RSSDiv { background-color:White; position:absolute; top:100px; left:300px; width:800px; height:600px; border:1px solid black; display:none; } Now that the HTML content to display above the Silverlight control is set, how can we show it as a user clicks a HyperlinkButton or other control in the application? Fortunately, Silverlight provides an excellent HTML bridge that allows direct access to content hosted within a page. The following code shows two JavaScript functions that can be called from Siverlight to handle showing or hiding HTML overlay content. The two functions rely on jQuery (http://www.jQuery.com) to make it easy to select HTML objects and manipulate their properties: function ShowOverlay() { rssDiv.css('display', 'block'); } function HideOverlay() { rssDiv.css('display', 'none'); } Calling the ShowOverlay function is as simple as adding the following code into the Silverlight application within a button’s Click event handler: private void OverlayHyperlinkButton_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.Invoke("ShowOverlay"); } The result of setting the Silverlight control’s windowless parameter to true and showing the HTML overlay content is shown in the following screenshot:   Thinking Outside the Box to Show HTML Content Setting the windowless parameter to true may not be a viable option for some Silverlight applications or you may simply want to go about showing HTML content a different way. The next technique I’ll show takes advantage of simple HTML, CSS and JavaScript code to handle showing HTML content while a Silverlight application is running in the browser. Keep in mind that with Silverlight’s HTML bridge feature you can always pop-up HTML content in a new browser window using code similar to the following: System.Windows.Browser.HtmlPage.Window.Navigate( new Uri("http://silverlight.net"), "_blank"); For this example I’ll demonstrate how to hide the Silverlight application while maximizing a container div containing the HTML content to show. This allows HTML content to take up the full screen area of the browser without having to set windowless to true and when done right can make the user feel like they never left the Silverlight application. The following HTML shows several div elements that are used to display HTML within the same browser window as the Silverlight application: <div id="JobPlanDiv"> <div style="vertical-align:middle"> <img alt="Close Button" align="right" src="Images/Close.png" onclick="HideJobPlanIFrame();" style="cursor:pointer;" /> </div> <div id="JobPlan_IFrame_Container" style="height:95%;width:100%;margin-top:37px;"></div> </div> The JobPlanDiv element acts as a container for two other divs that handle showing a close button and hosting an iframe that will be added dynamically at runtime. JobPlanDiv isn’t visible when the Silverlight application loads due to the following ID selector added into the page: #JobPlanDiv { position:absolute; background-color:#484848; overflow:hidden; left:0; top:0; height:100%; width:100%; display:none; } When the HTML content needs to be shown or hidden the JavaScript functions shown next can be used: var jobPlanIFrameID = 'JobPlan_IFrame'; var slHost = null; var jobPlanContainer = null; var jobPlanIFrameContainer = null; var rssDiv = null; $(document).ready(function () { slHost = $('#silverlightControlHost'); jobPlanContainer = $('#JobPlanDiv'); jobPlanIFrameContainer = $('#JobPlan_IFrame_Container'); rssDiv = $('#RSSDiv'); }); function ShowJobPlanIFrame(url) { jobPlanContainer.css('display', 'block'); $('<iframe id="' + jobPlanIFrameID + '" src="' + url + '" style="height:100%;width:100%;" />') .appendTo(jobPlanIFrameContainer); slHost.css('width', '0%'); } function HideJobPlanIFrame() { jobPlanContainer.css('display', 'none'); $('#' + jobPlanIFrameID).remove(); slHost.css('width', '100%'); } ShowJobPlanIFrame() handles showing the JobPlanDiv div and adding an iframe into it dynamically. Once JobPlanDiv is shown, the Silverlight control host has its width set to a value of 0% to allow the control to stay alive while making it invisible to the user. I found that this technique works better across multiple browsers as opposed to manipulating the Silverlight control host div’s display or visibility properties. Now that you’ve seen the code to handle showing and hiding the HTML content area, let’s switch focus to the Silverlight application. As a user clicks on a link such as “View Report” the ShowJobPlanIFrame() JavaScript function needs to be called. The following code handles that task: private void ReportHyperlinkButton_Click(object sender, RoutedEventArgs e) { ShowBrowser(_BaseUrl + "/Report.aspx"); } public void ShowBrowser(string url) { HtmlPage.Window.Invoke("ShowJobPlanIFrame", url); } Any URL can be passed into the ShowBrowser() method which handles invoking the JavaScript function. This includes standard web pages or even PDF files. We’ve used this technique frequently with our SmartPrint control (http://www.smartwebcontrols.com) which converts Silverlight screens into PDF documents and displays them. Here’s an example of the content generated:   Silverlight 4’s WebBrowser Control Both techniques shown to this point work well when Silverlight is running in-browser but not so well when it’s running out-of-browser since there’s no host page that you can access using the HTML bridge. Fortunately, Silverlight 4 provides a WebBrowser control that can be used to perform the same functionality quite easily. We’re currently using it in client applications to display PDF documents, SSRS reports and standard HTML content. Using the WebBrowser control simplifies the application quite a bit since no JavaScript is required if the application only runs out-of-browser. Here’s a simple example of defining the WebBrowser control in XAML. I typically define it in MainPage.xaml when a Silverlight Navigation template is used to create the project so that I can re-use the functionality across multiple screens. <Grid x:Name="WebBrowserGrid" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Visibility="Collapsed"> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Border Background="#484848" HorizontalAlignment="Stretch" Height="40"> <Image x:Name="WebBrowserImage" Width="100" Height="33" Cursor="Hand" HorizontalAlignment="Right" Source="/HTMLAndSilverlight;component/Assets/Images/Close.png" MouseLeftButtonDown="WebBrowserImage_MouseLeftButtonDown" /> </Border> <WebBrowser x:Name="JobPlanReportWebBrowser" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> </StackPanel> </Grid> Looking through the XAML you can see that a close image is defined along with the WebBrowser control. Because the URL that the WebBrowser should navigate to isn’t known at design time no value is assigned to the control’s Source property. If the XAML shown above is left “as is” you’ll find that any HTML content assigned to the WebBrowser doesn’t display properly. This is due to no height or width being set on the control. To handle this issue the following code is added into the XAML’s code-behind file to dynamically determine the height and width of the page and assign it to the WebBrowser. This is done by handling the SizeChanged event. void MainPage_SizeChanged(object sender, SizeChangedEventArgs e) { WebBrowserGrid.Height = JobPlanReportWebBrowser.Height = ActualHeight; WebBrowserGrid.Width = JobPlanReportWebBrowser.Width = ActualWidth; } When the user wants to view HTML content they click a button which executes the code shown in next: public void ShowBrowser(string url) { if (Application.Current.IsRunningOutOfBrowser) { JobPlanReportWebBrowser.NavigateToString("<html><body><iframe src='" + url + "' style='width:100%;height:97%;' /></body></html>"); WebBrowserGrid.Visibility = Visibility.Visible; } else { HtmlPage.Window.Invoke("ShowJobPlanIFrame", url); } } private void WebBrowserImage_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { WebBrowserGrid.Visibility = Visibility.Collapsed; }   Looking through the code you’ll see that it checks to see if the Silverlight application is running out-of-browser and then either displays the WebBrowser control or runs the JavaScript function discussed earlier. Although the WebBrowser control’s Source property could be assigned the URI of the page to navigate to, by assigning HTML content using the NavigateToString() method and adding an iframe, content can be shown from any site including cross-domain sites. This is especially handy when you need to grab a page from a reporting site that’s in a different domain than the Silverlight application. Here’s an example of viewing  PDF file inside of an out-of-browser application. The first image shows the application running out-of-browser before the user clicks a PDF HyperlinkButton.  The second image shows the PDF being displayed.   While there are certainly other techniques that can be used, the ones shown here have worked well for us in different applications and provide the ability to display HTML content in-browser or out-of-browser. Feel free to add a comment if you have another tip or trick you like to use when working with HTML content in Silverlight applications.   Download Code Sample   For more information about onsite, online and video training, mentoring and consulting solutions for .NET, SharePoint or Silverlight please visit http://www.thewahlingroup.com.
