  • wsdl xml parsing , maxlength problem after encoding of text

    - by MichaelD
    We are working together with another firm. our application communicates with the other application through WCF on our side and a custom implemented java wsdl handler on the other side. They specify the wsdl format and one of the rules is that a specific string cannot contain more then 15 characters. (normally it's 60, but i take 15 for easy example reasons) When we try to send the following string to them we get an error that the string is too long according to the wsdl: "example & test" this is a string of 14 characters, so it should be allowed the microsoft wcf parser translates this to "example &amp; test" . This encoded string is 18 characters long. Now what is the standaard behavior to check a maxlength defined in a message? Is it the encoded message or the decoded message? I would think it's the decoded message , but i ain't sure. If it is the encoded message, how should we handle this so we would know how we have to split the string?

  • Why does my javascript file sometimes compressed while sometimes not?(IIS Gzip problem)

    - by Kevin Yang
    i enable gzip for javascript file in my iis settings, here 's the corresponding config section. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" staticCompressionLevel="10" dynamicCompressionLevel="8" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/soap+msbin1" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression> currently, when i download my js file, it seems that sometimes server return the gzip one, and sometimes not. i dont know why, and how to debug that. If a file is already gzipped, it should be cached in local disk, and next time someone visit that file again, iis kernel should return the cache gzip file directly without compressing it again. Is that right?

  • Problem of using cin twice.

    - by gc
    Here is the code: string str; cinstr; cout<<"first input:"<<str<<endl; getline(cin, str); cout<<"line input:"<<str<<endl; The result is that getline never pauses for user input, therefore the second output is always empty. After spending some time on it, I realized after the first call "cinstr", it seems '\n' is still stored in cin (using cin.peek() to check), which ends getline immediately. The solution will be adding one more line between the first usage and the second one: cin.ignore(numeric_limits::max(), '\n'); However, I still don't understand, why is '\n' left there after the first call? What does istream& operator really do?

  • ActionScript 2.0 problem with the object's _visible parameter

    - by GMan
    Hey guys, I've been trying to build something simple in Flash 8, and I stumbled across something weird I cannot explain: I have an object, and at some point of the program, I want it to be visible (it is invisible at first), so I write: _root.myObj._visible = true; _root.gameOver.swapDepths(_root.getNextHighestDepth()); //so it will be on the top and this works fine, the object becomes visible and etc. What I planned to happen next is that the user presses a button on that same object, and the object will go invisible: on(release) { trace(_root.myObj._visible); _root.myObj._visible = false; trace(_root.myObj._visible); _root.gotoAndPlay("three"); } The trace returns at first true and later on false, so the command works, but oddly the object stays visible, that's what I don't understand. Thanks everybody in advance.

But to call this method at the very beginning when the MyControl is created? I need to prove immediate after initialize if the there's a null value in the control (and display a validation error)

  • any suggestions on this css print problem

    - by user225269
    I have this code on my print.css: #header, #tae, #nav, .noprint {display: none;} width: 100%; margin: 0; float: none; In order not to display the elements within those div tags. But I don't know with the code below why it isn't cooperating. If I place the div tags on it. And then I hit the print button. I see no output. Here it is: <div id="tae"> <table border="0" align="center" cellpadding="0" cellspacing="0" class="bg1"> <tr> <td class="text1" style="height: 50px;">xd627 information management system</td> </tr> <tr> <td class="bg5"><table border="0" cellspacing="0" cellpadding="0" style="height: 62px; padding-top: 15px;"> <tr align="center"> <td><a href="userpage.php" class="link1">Homepage</a></td> <td><a href="RegStuds.php" class="link1">Database</a></td> <td><a href="#" class="link1">About</a></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> </table></td> </tr> <tr> <td valign="top" class="bg6">&nbsp;</td> </tr> <tr> <td><table width="780" border="0" cellspacing="0" cellpadding="0"> <tr valign="top"> <td width="20">&nbsp;</td> <td width="297"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td><img src="images/spacer.gif" alt="" width="30" height="30" /></td> </tr> </tr> <tr> <td class="text2"> </div> <div id="max"> <?php //some php code in here showing a mysql table. ?> </div> What's wrong with my code? Does the php script depend on the one where I put the div tag in? What do I do? All I want to show up in my page when printed is the mysql table. I'm using Universal Document Converter to simulate printing.

  • Simple CanCan problem

    - by sscirrus
    I have just started with CanCan and here's a sample of the code: # Ability.rb def initialize(user) user ||= User.new can :read, Link end # view.html.erb <% if can? :read, @link %> ... <% end %> This is from the github repo for CanCan but this doesn't seem to work (it returns false and stops the ... code from running). When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?

    Hi, This wasn't the question I was going to ask but I have unexpectedly run aground with JavaScript arrays. I come from a PHP background and after looking at a few websites I am none the wiser. I am trying to create a multi-dimensional array. var photos = new Array; var a = 0; $("#photos img").each(function(i) { photos[a]["url"] = this.src; photos[a]["caption"] = this.alt; photos[a]["background"] = this.css('background-color'); a++; }); Error message: photos[a] is undefined. How do I do this. Thanks.

  • MySQL join problem

    - by David
    Table1 has u_name, Table2 has u_name, u_type and u_admin Table1.u_name is unique. But neither of the 3 fields in Table2 is unique. For any value of Table1.u_name, there are 0 to many entries in Table2 that Table2.u_name equals to that value. For any value of Table1.u_name, there are 0 to 1 entries in Table2 that Table2.u_name equals to that value AND Table2.u_type='S' What I want: Use Table1.u_name to get Table1.*, Table2.u_admin where Table1.u_name=Tabl2.u_name and Table2.u_type='S'. If there is no such entry in Table2 we still need to get Table1.* Please help give me some hints. Thank you so much!

  • Strange problem with PHP and sessions

    - by Jhorra
    So the basis of this page is I set a session value when the page loads, and clear it on any other page they visit. Then the page can make an ajax call to download a file. If the session value matches the value I pass through the URL I allow them to download the file. If not I return a 404 error. I was having some weird issues, so I removed the 404 and set it to echo out the values instead to see what I was getting. Here is the top of the code on the page: $code = $this->_request->getParam('code'); $confirm = $_SESSION['mp3_code']; echo $code."-1-".$confirm; if($code != $confirm) echo $code."-2-".$confirm;//header("HTTP/1.1 404 Not Found"); else { Here is what displays on the page from the ajax call 12723430-1-12723430-2- As you can see when it echos out the first time they exist, then somehow after I compare them and it fails you see that it echos out blank values like they suddenly ceased to exist. Any ideas?

  • Problem creating calculations 'engine' in two class java calculator

    - by tokee
    i have hit a brick wall whilst attempting to create a two class java calculator but have been unsuccessful so far in getting it working. i have the code for an interface which works and displays ok but creating a seperate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which works with the interface class and allows input when from single button i.e. if one is pressed on the calc then 1 displays onscreen. please note i'm not asking someone to do the whole thing for me as i want to learn and i'm confident i can do the rest including addition subtraction etc. once i get over the obstacle of getting the two classes to communicate. any and all assistance would be very much appreciated. Please see the calcInterface class code below - import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.*; /** *A Class that operates as the framework for a calculator. *No calculations are performed in this section */ public class CalcFrame implements ActionListener { private CalcEngine calc; private JFrame frame; private JTextField display; private JLabel status; /** * Constructor for objects of class GridLayoutExample */ public CalcFrame() { makeFrame(); //calc = engine; } /** * This allows you to quit the calculator. */ // Alows the class to quit. private void quit() { System.exit(0); } // Calls the dialog frame with the information about the project. private void showAbout() { JOptionPane.showMessageDialog(frame, "Group Project", "About Calculator Group Project", JOptionPane.INFORMATION_MESSAGE); } private void makeFrame() { frame = new JFrame("Group Project Calculator"); makeMenuBar(frame); JPanel contentPane = (JPanel)frame.getContentPane(); contentPane.setLayout(new BorderLayout(8, 8)); contentPane.setBorder(new EmptyBorder( 10, 10, 10, 10)); /** * Insert a text field */ display = new JTextField(); contentPane.add(display, BorderLayout.NORTH); //Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(4, 4)); JPanel buttonPanel = new JPanel(new GridLayout(4, 4)); contentPane.add(new JButton("1")); contentPane.add(new JButton("2")); contentPane.add(new JButton("3")); contentPane.add(new JButton("4")); contentPane.add(new JButton("5")); contentPane.add(new JButton("6")); contentPane.add(new JButton("7")); contentPane.add(new JButton("8")); contentPane.add(new JButton("9")); contentPane.add(new JButton("0")); contentPane.add(new JButton("+")); contentPane.add(new JButton("-")); contentPane.add(new JButton("/")); contentPane.add(new JButton("*")); contentPane.add(new JButton("=")); contentPane.add(new JButton("C")); contentPane.add(buttonPanel, BorderLayout.CENTER); //status = new JLabel(calc.getAuthor()); //contentPane.add(status, BorderLayout.SOUTH); frame.pack(); frame.setVisible(true); } /** * Create the main frame's menu bar. * The frame that the menu bar should be added to. */ private void makeMenuBar(JFrame frame) { final int SHORTCUT_MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask(); JMenuBar menubar = new JMenuBar(); frame.setJMenuBar(menubar); JMenu menu; JMenuItem item; // create the File menu menu = new JMenu("File"); menubar.add(menu); // create the Quit menu with a shortcut "Q" key. item = new JMenuItem("Quit"); item.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, SHORTCUT_MASK)); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { quit(); } }); menu.add(item); // Adds an about menu. menu = new JMenu("About"); menubar.add(menu); // Displays item = new JMenuItem("Calculator Project"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { showAbout(); } }); menu.add(item); } /** * An interface action has been performed. * Find out what it was and handle it. * @param event The event that has occured. */ public void actionPerformed(ActionEvent event) { String command = event.getActionCommand(); if(command.equals("0") || command.equals("1") || command.equals("2") || command.equals("3") || command.equals("4") || command.equals("5") || command.equals("6") || command.equals("7") || command.equals("8") || command.equals("9")) { int number = Integer.parseInt(command); calc.numberPressed(number); } else if(command.equals("+")) { calc.plus(); } else if(command.equals("-")) { calc.minus(); } else if(command.equals("=")) { calc.equals(); } else if(command.equals("C")) { calc.clear(); } else if(command.equals("?")) { } // else unknown command. redisplay(); } /** * Update the interface display to show the current value of the * calculator. */ private void redisplay() { display.setText("" + calc.getDisplayValue()); } /** * Toggle the info display in the calculator's status area between the * author and version information. */ }

  • problem adding object to hashtable

    - by daemonkid
    I am trying to call a class method dynamically depending on a condition. This is how I am doing it I have three classes implement a single interface interface IReadFile { string DoStuff(); } The three classes A,B,C implement the interface above. I am trying to add them to a hashtable with the code below _HashT.Add("a", new classA()); _HashT.Add("b", new classB()); _HashT.Add("c", new classC()); This compiles fine, but gives a runtime error.{Object reference not set to an instance of an object.} I was planning to return the correct class to the interface type depending on a parameter that matches the key value. say if I send in a. ClassA is returned to the interface type and the method is called. IReadFile Obj = (IReadFile )_HashT["a"].GetType(); obj.DoStuff(); How do I correct the part above where the objects need to be added to the hashtable? Or do I need to use a different approach? All the classes are in the same assembly and namespace. Thanks for your time.

  • Google Maps 'API key' problem

They're saying the following error message appears "This web site needs a different Google Maps API key. A new key can be generated at..." Here's the page: http://www.sportingemporium.com/google-map.htm When I sign-up for a new key Goggle gives me exactly the same one that I am already using! If anyone can shed any light on why I (and colleagues in many different countries) can see the map, but the client can't, it would be greatly appreiciated? Kind regards, Declan Bradley
