  • How to clear a bean field with Stripes.

    - by Davoink
    In a JSP I have the following field: <stripes:text name="email"/> This field is in my action bean(snippet): public class CreateClaim implements ActionBean { private String email; public void setEmail(String email) { this.email = email; } public String getEmail() { return email; } public Resolution alc(){ email = "poodle"; return new ForwardResolution("aForward.jsp"); } } In the alc() methos I am setting email to be null. But when the pages renders the value of the email field is exactly as it was entered originally. Is there a way of clearing this field once and event has triggered? Cheers Dave

  • C++ Ambiguous call to Overloaded Function (const variety)

    - by Joe
    After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

  • Converting F# Quotations into LINQ Expressions

    - by forki23
    Hi, I can convert a quotation of type Expr<'a -> 'b> to a Linq expression via the following snippet: /// Converts a F# Expression to a LINQ Lambda let toLambda (exp:Expr) = let linq = exp.ToLinqExpression() :?> MethodCallExpression linq.Arguments.[0] :?> LambdaExpression /// Converts a Lambda quotation into a Linq Lamba Expression with 1 parameter let ToLinq (exp : Expr<'a -> 'b>) = let lambda = toLambda exp Expression.Lambda<Func<'a, 'b>>(lambda.Body, lambda.Parameters) Now I want to convert a quotation of type Expr<'a * 'b -> 'c> or maybe even Expr<'a -> 'b -> 'c> to a Linq Lambda Expression of type Expression<Func<'a,'b'c>>. How can I do this? Regards, forki

  • Custom QGraphicsItems not compiling and gives "object is private" error

    - by bahree
    Hi, I am trying to create a Custom QGraphicsItem button as shown by Fred here. The code which he posted can be found here. The problem is when I try and compile the code I get the following two errors: /usr/include/qt4/QtGui/qgraphicsitem.h ‘QGraphicsItem::QGraphicsItem(const QGraphicsItem&)’ is private /usr/include/qt4/QtCore/qobject.h ‘QObject::QObject(const QObject&)’ is private Here is the code snippet which essentially is the same as that in the sample above. The error is on the class deceleration. class MyButton : public QObject, public QGraphicsItem { Q_OBJECT Q_INTERFACES(QGraphicsItem) public: MyButton(QGraphicsItem *parent = 0); MyButton(const QString normal, const QString pressed = "", QGraphicsItem *parent = 0); .... } Interestingly the other sample as shown here works fine. The sample code for that can be found here. Any idea what is wrong? Thanks in advance.

  • C# - Angle between two 2d vectors, diff between two methods?

    - by Sean Ochoa
    Hey all. I've got this code snippet, and I'm wondering why the results of the first method differ from the results of the second method, given the same input? public double AngleBetween_1(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = Len*b.Len; var divOperation = dotProd/lenProd; return Math.Acos(divOperation) * (180.0 / Math.PI); } public double AngleBetween_2(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = Len*b.Len; var divOperation = dotProd/lenProd; return (1/Math.Cos(divOperation)) * (180.0 / Math.PI); }

  • phpbb template comment conditional

    - by john
    I see in PHPBB they use conditional statements inside their html, or xhtml, if you dont know what I mean here is a snippet: <!-- IF MODERATORS --> <p class="moderators"><!-- IF S_SINGLE_MODERATOR -->{L_MODERATOR}<!-- ELSE -->{L_MODERATORS}<!-- ENDIF -->: {MODERATORS}</p> <!-- ENDIF --> <!-- IF U_MCP --> <p class="linkmcp">[ <a href="{U_MCP}">{L_MCP}</a> ]</p> <!-- ENDIF --> Is there an explanation on how to implement this in my own site, as it would be very useful and clean up a lot of code.

  • How do I do a postback to a CGI service

    - by TheLearner
    I am building a C# client for a CGI service (not sure what its called exactly). It accepts a bunch of XML and spits out a response. I have tested it straight in Firefox and it works (see below). Now I am not sure how to do this in C# code though? Does anyone have a helpful snippet of code, I can't imagine it would be that difficult? http://www.travelcommunications.co.uk/cgi-bin/d3web_gzip.ssh?%3CTCOML%20version=%22NEWFORMAT%22%3E%3CTransferOnly%3E%3CAvailability%3E%3CRequest%3E%3CAgentCode%3ETEST%3C/AgentCode%3E%3CAgentType%3ETA%3C/AgentType%3E%3CDeparturePointCode%3EALC%3C/DeparturePointCode%3E%3CDeparturePointType%3EAIRPORT%3C/DeparturePointType%3E%3CArrivalPointCode%3EBEN%3C/ArrivalPointCode%3E%3CArrivalPointType%3ERESORT%3C/ArrivalPointType%3E%3CSectorType%3ERETURN%3C/SectorType%3E%3CArrDate%3E10.10.10%3C/ArrDate%3E%3CArrTime%3E10:00%3C/ArrTime%3E%3CRetDate%3E17.10.10%3C/RetDate%3E%3CRetTime%3E10:00%3C/RetTime%3E%3CBrochure%3E001%3C/Brochure%3E%3CAdults%3E2%3C/Adults%3E%3CChildren%3E0%3C/Children%3E%3CInfants%3E0%3C/Infants%3E%3CCurrencyCode%3EUKL%3C/CurrencyCode%3E%3C/Request%3E%3C/Availability%3E%3C/TransferOnly%3E%3C/TCOML%3E

  • AES Encryption. From Python (pyCrypto) to .NET

    - by Why
    I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

  • jsf flash.keep and redirects does not seem to work

    - by user384706
    Hi, I am trying to use JSF 2.0 flash via redirects. I have a class named UserBean (ManagedScoped and RequestScoped). It has a method called getValuesFromFlash which essentially gets the values from the flash and sets the coresponding properties of the UserBean public void getValuesFromFlash() { Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash(); firstName= (String) flash.get("firstName"); lastName = (String) flash.get("lastName"); } In the entry page the <h:inputText> are bound to the flash. Snippet follows: Entry.xhtml <h:form> <table> <tr> <td>First Name:</td> <td> <h:inputText id="fname" value="#{flash.firstName}" required="true"/> <h:message for="fname" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:inputText id="lname" value="#{flash.lastName}" required="true"/> <h:message for="lname" /> </td> </tr> </table <p><h:commandButton value="Submit" action="confirmation?faces-redirect=true" /></p> </h:form> In confirmation.xhtml these values are supposed to be displayed but they are not. Snippet follows: <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{flash.keep.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{flash.keep.lastName}"/> </td> </tr> </table> <h:form> <p><h:commandButton value="Confirm" action="finished?faces-redirect=true" /></p> </h:form> In finished.xhtml I want all these to be displayed so: <h:body> <h:form> #{userBean.getValuesFromFlash( )} <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{userBean.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{userBean.lastName}"/> </td> </tr> </table> </h:form> </h:body> Instead when I get redirected to confirmation.xhtml neither first nor last name is displayed, despite I used flash.keep Also in finished.xhtml I get org.apache.el.parser.ParseException: Encountered " "(" "( "" at line 1, column 30. Was expecting one of: "}" ... "." If I remove the parenthesis from the expression #{userBean.getValuesFromFlash( )} and make it = #{userBean.getValuesFromFlash} javax.el.ELException: /done.xhtml: Property 'getValuesFromFlash' not found on type com.UserBean But why no property??It is a method! Why is the method not visible? What I am doing wrong here please? I am using JSF2.0 (MyFaces), Eclipse Helios and Tomcat 6 (Have also tried in Tomcat 7 but no luck). Any help is appreciated. Thanks!

  • python duration of a file object in an argument list

    - by msw
    In the pickle module documentation there is a snippet of example code: reader = pickle.load(open('save.p', 'rb')) which upon first read looked like it would allocate a system file descriptor, read its contents and then "leak" the open descriptor for there isn't any handle accessible to call close() upon. This got me wondering if there was any hidden magic that takes care of this case. Diving into the source, I found in Modules/_fileio.c that file descriptors are closed by the fileio_dealloc() destructor which led to the real question. What is the duration of the file object returned by the example code above? After that statement executes does the object indeed become unreferenced and therefore will the fd be subject to a real close(2) call at some future garbage collection sweep? If so, is the example line good practice, or should one not count on the fd being released thus risking kernel per-process descriptor table exhaustion?

  • Live Character Count For EditText Android

    - by Taylor Perkins
    Hello, I was wondering what the best way to do a live character count of an edit-text box is in Android. I was looking at this but I couldn't seem to make any sense of it. To describe the problem, I have an EditText and I'm trying to limit the characters to 150. I can do this with an input filter, however I want to show right below the text box the number of characters a user has entered(Almost like stack overflow is doing right now). If someone could write a small snippet of example code or point me in the right direction I'd appreciate it a lot. Thanks in advance.

  • Resharper and var

    - by Refracted Paladin
    I have Resharper 4.5 and have found it invaluable so far but I have a concern; It seems to want to make every variable declaration implicit(var). As a relativly new developer how much should I trust ReSharper when it comes to this? Take the below code snippet from a method that Paints Tab Headers. TabPage currentTab = tabCaseNotes.TabPages[e.Index]; Rectangle itemRect = tabCaseNotes.GetTabRect(e.Index); SolidBrush fillBrush = new SolidBrush(Color.Linen); SolidBrush textBrush = new SolidBrush(Color.Black); StringFormat sf = new StringFormat { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center }; Resharper wants me to change all 5 of those to var. I have read the following similar post,Use of var keyword in C#, but I would like to know from a Resharper standpoint. Thanks!

  • How do I get Java to use my multi-core processor?

    - by Rudiger
    I'm using a GZIPInputStream in my program, and I know that the performance would be helped if I could get Java running my program in parallel. In general, is there a command-line option for the standard VM to run on many cores? It's running on just one as it is. Thanks! Edit I'm running plain ol' Java SE 6 update 17 on Windows XP. Would putting the GZIPInputStream on a separate thread explicitly help? No! Do not put the GZIPInputStream on a separate thread! Do NOT multithread I/O! Edit 2 I suppose I/O is the bottleneck, as I'm reading and writing to the same disk... In general, though, is there a way to make GZIPInputStream faster? Or a replacement for GZIPInputStream that runs parallel? Edit 3 Code snippet I used: GZIPInputStream gzip = new GZIPInputStream(new FileInputStream(INPUT_FILENAME)); DataInputStream in = new DataInputStream(new BufferedInputStream(gzip));

  • PHP does not return errors at all

    - by ErJab
    I am running PHP and nginx and I use a production version of php.ini. So the variable display_error is set to Off and there is a good reason I want it this way. But for certain files I need to enable error reporting. I used ini_set to turn on error reporting. But a simple code snippet like: <?php error_reporting(E_ALL); ini_set("display_errors", 1); echo "hi"errorrrrr ?> does not trace the error. It simply returns a HTTP 500 Internal Server Error message. What should I do to enable error reporting?

  • ASP.NET - Overriding Gridview OnRowCreated to add sort images -- columns are null

    - by Zach
    I'm overriding the onrowcreated to add sort images to the header row of a gridview. This works, but actually adding a sortexpression doesn't. What I want to do is set the images as imagebuttons and set their commandarguments to the sort expression of the column they are sorting for. I would assume I could get the cell and from it's index get the gridviewcolumn. Then, I could just get the sortexpression of the gridview column, but this does not work. The columns are null. OnRowCreated Code snippet below: //if this is the header row, we add sort images to each cell if (row.RowType == DataControlRowType.Header) { //iterate through the cells for (int i = 0; i < row.Cells.Count; i++) { //if the column is sortable and visible if (this.Columns[i].SortExpression != string.Empty && this.Columns[i].Visible) { string strSort = this.Columns[i].SortExpression; } } } Can we not get columns in OnRowCreated like this?

  • Issue with multipart upload in servlet on seam

    I created a servlet wich works fine when deployed in a separate war file, but I intend to use it as part of a seam application. I use commons-fileupload but the iterator (see snippet) returns false (only when included in the seam-app). Any ideas? protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { String action = request.getParameter( "action" ); if ( ServletFileUpload.isMultipartContent( request ) ) { log.info( "MULTIPART" ); } ServletFileUpload upload = new ServletFileUpload(); FileItemIterator iter = upload.getItemIterator( request ); // --------- hasNext() returns false, only in seam ----------- while ( iter.hasNext() ) { ...... } Additional Info: I don't want to use the technique described here since the uploading client is curl. The HttpServletRequest is wrapped by org.jboss.seam.web.IdentityRequestWrapper Using the seam

  • C# Silverlight - XmlDictionary from Uri

    - by Robert White
    I've been developing a Silverlight application for a company's website and have encountered a problem. Up until now I have been programming this locally, now I need to publish the program onto the website; the issue is that FileStream can only access local files with elevated permissions. Here's a snippet of code: using (FileStream fileStream = new FileStream(@"E:\Users\LUPUS\Documents\Visual Studio 2010\Projects\Lycaon5\Lycaon5\acids.xdb", FileMode.Open)) { using (XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(fileStream, XmlDictionaryReaderQuotas.Max)) { //Read the XML file out. } } Without changing anything to do with XmlDictionaryReader reader - How could I go about reading the files from a relative Uri? Many Thanks, Rob. P.s. Apologies for the lack of formatting, me cave man, me don't know how.

  • SQL Server won't perform regular expression validation on XML column

    - by Kirk Broadhurst
    Hi I have an XML column in my table which contains this xsd snippet: <xsd:element name="Postcode" minOccurs="0"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:pattern value="^[0-9]{4}$" /> </xsd:restriction> </xsd:simpleType> </xsd:element> The regular expression should require a string containing 4 numerical digits. It validates perfectly in Visual Studio and is a correct regular expression. SQL Server, on the other hand, won't accept it. The error message I receive is: XML Validation: Invalid simple type value: '1234'. Location: / * : Donor[1]/*:Postcode[1]. I have an email address regex working fine, but can't get this simple numerical regex to work.

  • var undefined = true;

    - by Andreas Grech
    I'm doing some experimenting with this malicious JavaScript line: var undefined = true; Every uninitialized variable in JavaScript has the value of undefined which is just a variable that holds the special value of 'undefined', so the following should execute the alert: var undefined = true, x; if (x) { alert('ok'); } But it doesn't, and my question is why? On further experimentation, I tried the following: var undefined = true, x = undefined; if (x) { alert('ok'); } This time, the alert is executed. So my question is...since in the first snippet x holds undefined (because it is not initialized), why didn't the alert execute? The strange thing is that when explicitly stating that x is undefined (x = undefined), the alert executed...
