  • Html.LabelFor and Html.TextBoxFor generate empy html code

    - by Ceridan
    I'm writing my first ASP.NET MVC application and there is one big problem for me. I want to make a control which will represent a form, but when I try to generate labels and textboxes it returns to me empty page. So, this is my model file (MyModel.cs): namespace MyNamespace.Models { public class MyModel { [Required(ErrorMessage = "You have to fill this field")] [DisplayName("Input name")] public string Name{ get; set; } } } This is MyFormControlView.ascx file with my control: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyNamespace.Models.MyModel>"%> <div> <% using (Html.BeginForm()) { Html.LabelFor(m => m.Name); Html.TextBoxFor(m => m.Name); Html.ValidationMessageFor(m => m.Name); } %> </div> And this is my Index.aspx file where I render the control: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Main.Master" Inherits="System.Web.Mvc.ViewPage<System.Collections.IEnumerable>" %> <asp:Content runat="server" ID="MainContent" ContentPlaceHolderID="MainContent"> This is my control test! <%Html.RenderPartial("MyFormControlView", new MyNamespace.Models.MyModel { Name = "MyTestName"}); %> </asp:Content> So, when I run my application the result is lonely caption: "This is my control test!" and there are no label or textbox on the generated page. If I inspect the source code of the generated page I can see my block, but it's inner text is empty. Please, could you help me?

  • Need help making a check statement to make sure al the controls are not blank

    - by Michael Quiles
    This is for a tic tac toe game. I need help making a check statement to see if all the controls' Texts are non-blank, and if they are, you have a draw (if someone had won the previous code would have discovered that). Can you give me a good example using my code. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Drawing; namespace MyGame { public class Result1 { static private int[,] Winners = new int[,] { // main gameplay Ex: if x is on 0,1,2 x is the winner {0,1,2}, {3,4,5}, {6,7,8}, {0,3,6}, {1,4,7}, {2,5,8}, {0,4,8}, {2,4,6}, }; static public bool CheckWinner(Button[] myControls) { //bolean statement to check for the winner bool gameOver = false; for (int i = 0; i < 8; i++) { int a = Winners[i, 0]; int b = Winners[i, 1]; int c = Winners[i, 2]; Button b1 = myControls[a], b2 = myControls[b], b3 = myControls[c]; if (b1.Text == "" || b2.Text == "" || b3.Text == "") continue; if (b1.Text == b2.Text && b2.Text == b3.Text) { b1.BackColor = b2.BackColor = b3.BackColor = Color.LightCoral; b1.Font = b2.Font = b3.Font = new System.Drawing.Font("Microsoft Sans Serif", 32F, System.Drawing.FontStyle.Italic & System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0))); gameOver = true; xWinnerForm xWinnerForm = new xWinnerForm(); xWinnerForm.ShowDialog(); //only works with show not showDialog method gets overloaded (b1.Text + " is the Winner"); to get around this I added and image showing the last player } } return gameOver; } } }

  • sharp architecture question

    - by csetzkorn
    I am trying to get my head around the sharp architecture and follow the tutorial. I am using this code: using Bla.Core; using System.Collections.Generic; using Bla.Core.DataInterfaces; using System.Web.Mvc; using SharpArch.Core; using SharpArch.Web; using Bla.Web; namespace Bla.Web.Controllers { public class UsersController { public UsersController(IUserRepository userRepository) { Check.Require(userRepository != null,"userRepository may not be null"); this.userRepository = userRepository; } public ActionResult ListStaffMembersMatching(string filter) { List<User> matchingUsers = userRepository.FindAllMatching(filter); return View("ListUsersMatchingFilter", matchingUsers); } private readonly IUserRepository userRepository; } } I get this error: The name 'View' does not exist in the current context I have used all the correct using statements and referenced the assemblies as far as I can see. The views live in Bla.Web in this architecture. Can anyone see the problem? Thanks. Christian

  • PDCurses TUI C++ Win32 console app - Access violation reading location

    - by Bach
    I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime, which suggests a bad pointer: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

  • This 404 seems unavoidable - what am I doing wrong? [Ninject 2.0 with ASP.NET MVC 2 on .NET 4]

    - by Tomas Lycken
    I downloaded the fairly new Ninject 2.0 and Ninject.Web.Mvc (targeting mvc2) sources today, and successfully built them against .NET 4 (release configuration). When trying to run an application using Ninject 2.0, i keep getting 404 errors and I can't figure out why. This is my global.asax.cs (slightly shortified, for brevity): using ... using Ninject; using Ninject.Web.Mvc; using Ninject.Modules; namespace Booking.Web { public class MvcApplication : NinjectHttpApplication { protected override void OnApplicationStarted() { Booking.Models.AutoMapperBootstrapper.Initialize(); RegisterAllControllersIn(Assembly.GetExecutingAssembly()); base.OnApplicationStarted(); } protected void RegisterRoutes(RouteCollection routes) { ... routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Entry", action = "Index", id = "" } ); } protected override IKernel CreateKernel() { INinjectModule[] mods = new INinjectModule[] {...}; return new StandardKernel(mods); } } } The EntryController exists, and has an Index method that simply does a return View(). I have debugged, and verified that the call to RegisterAllControllersIn() is executed. I have also tried to use Phil Haacks Routing debugger but I still get a 404. What do I do to find the cause of this?

  • Base class -> Derived class and vice-versa conversions in C++

    - by Ivan Nikolaev
    Hi! I have the following example code: #include <iostream> #include <string> using namespace std; class Event { public: string type; string source; }; class KeyEvent : public Event { public: string key; string modifier; }; class MouseEvent : public Event { public: string button; int x; int y; }; void handleEvent(KeyEvent e) { if(e.key == "ENTER") cout << "Hello world! The Enter key was pressed ;)" << endl; } Event generateEvent() { KeyEvent e; e.type = "KEYBOARD_EVENT"; e.source = "Keyboard0"; e.key = "SPACEBAR"; e.modifier = "none"; return e; } int main() { KeyEvent e = generateEvent(); return 0; } I can't compile it, G++ throws an error of kind: main.cpp: In function 'int main()': main.cpp:47:29: error: conversion from 'Event' to non-scalar type 'KeyEvent' requested I know that the error is obvious for C++ guru's, but I can't understand why I can't do the conversion from base class object to derived one. Can someone suggest me the solution of the problem that I have? Thx in advice

  • SimpleXML - "Node no longer exists"

    - by SubZane
    Hi I'm trying to get the video data from this youtube playlist feed and add the interesting data to an array and use that later, but as you can see from the feed some videolinks are "dead" and that results in problems for my code. The error I get is "Node no longer exists" when I try to access $attrs['url']. I've tried for hours to find a way to check if the node exists before I access it but I have no luck. If anyone could help me to either parse the feed some other way with the same result or create a if-node-exists check that works I would be most happy. Thank you in advance $url = 'http://gdata.youtube.com/feeds/api/playlists/18A7E36C33EF4B5D?v=2'; $sxml = simplexml_load_file($url); $i = 0; $videoobj; foreach ($sxml->entry as $entry) { // get nodes in media: namespace for media information $media = $entry->children('http://search.yahoo.com/mrss/'); // get video player URL $attrs = $media->group->player->attributes(); $videoobj[$i]['url'] = $attrs['url']; // get video thumbnail $attrs = $media->group->thumbnail[0]->attributes(); $videoobj[$i]['thumb'] = $attrs['url']; $videoobj[$i]['title'] = $media->group->title; $i++; }

  • Access Violation When Writing Dynamic 2D Array... Sometimes

    - by Shraptnel
    This program is meant to generate a dynamic array, however it gives an access violation error when writing when given certain dimensions. Eg: R = 6, C = 5 crashes, but then R = 5, C = 6 doesn't. In case your wondering, it isn't my homework to "fix" this broken program, this is the method we were taught in class. Also part of my assessment is to use this method, so vectors are out. Thanks in advance! #include <iostream> using namespace std; int main(){ const int R = 6; const int C = 5; char **d; d = new char *[R]; for(int i=0; i<C; ++i){ d[i] = new char[C]; } //initialise for(int i=0; i<R; ++i){ for(int j=0; j<C; ++j){ d[i][j] = 'd'; cout<<d[i][j]; } cout<<endl; } cout<<endl; system("pause"); return 0; }

  • Global Hotkey in Mono and Gtk#

    - by Zach Johnson
    I'm trying to get a global hotkey working in Linux using Mono. I found the signatures of XGrabKey and XUngrabKey, but I can't seem to get them working. Whenever I try to invoke XGrabKey, the application crashes with a SIGSEGV. This is what I have so far: using System; using Gtk; using System.Runtime.InteropServices; namespace GTKTest { class MainClass { const int GrabModeAsync = 1; public static void Main(string[] args) { Application.Init(); MainWindow win = new MainWindow(); win.Show(); // Crashes here XGrabKey( win.Display.Handle, (int)Gdk.Key.A, (uint)KeyMasks.ShiftMask, win.Handle, true, GrabModeAsync, GrabModeAsync); Application.Run(); XUngrabKey( win.Display.Handle, (int)Gdk.Key.A, (uint)KeyMasks.ShiftMask, win.Handle); } [DllImport("libX11")] internal static extern int XGrabKey( IntPtr display, int keycode, uint modifiers, IntPtr grab_window, bool owner_events, int pointer_mode, int keyboard_mode); [DllImport("libX11")] internal static extern int XUngrabKey( IntPtr display, int keycode, uint modifiers, IntPtr grab_window); } public enum KeyMasks { ShiftMask = (1 << 0), LockMask = (1 << 1), ControlMask = (1 << 2), Mod1Mask = (1 << 3), Mod2Mask = (1 << 4), Mod3Mask = (1 << 5), Mod4Mask = (1 << 6), Mod5Mask = (1 << 7) } } Does anyone have a working example of XGrabKey?

    hi, I have defined a web service that will return the data from my mysql data base. I have written the web service in php. Now I have defined a complex type as follows: $server->wsdl->addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' => array('name' => 'category_parent_id', 'type' => 'xsd:int'), 'category_child_id' => array('name' => 'category_child_id', 'type' => 'xsd:int'), 'category_list' => array('name' => 'category_list', 'type' => 'xsd:int') ) ); The above complex type is a row in a table in my database. Now my function must send an array of these rows so how do I achieve the same My code is as follows: require_once('./nusoap/nusoap.php'); $server = new soap_server; $server-configureWSDL('productwsdl', 'urn:productwsdl'); // Register the data structures used by the service $server-wsdl-addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' = array('name' = 'category_parent_id', 'type' = 'xsd:int'), 'category_child_id' = array('name' = 'category_child_id', 'type' = 'xsd:int'), 'category_list' = array('name' = 'category_list', 'type' = 'xsd:int') ) ); $server-register('getaproduct', // method name array(), // input parameters //array('return' = array('result' = 'tns:Category')), // output parameters array('return' = 'tns:Category'), // output parameters 'urn:productwsdl', // namespace 'urn:productwsdl#getaproduct', // soapaction 'rpc', // style 'encoded', // use 'Get the product categories' // documentation ); function getaproduct() { $conn = mysql_connect('localhost','root',''); mysql_select_db('sssl', $conn); $sql = "SELECT * FROM jos_vm_category_xref"; $q = mysql_query($sql); while($r = mysql_fetch_array($q)) { $items[] = array('category_parent_id'=$r['category_parent_id'], 'category_child_id'=$r['category_child_id'], 'category_list'=$r['category_list']); } return $items; } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server-service($HTTP_RAW_POST_DATA);

  • C# COM objects with VB6/asp error

    - by Ken
    I'm trying to expose a C# class library via COM so that I can use it in a classic asp web site. I've used sn - k, regasm and gacutil. About all I can do now though is echo back strings. Methods which take Class variables as input are not working for me. ie my test method EchoPerson(Person p) which returns a string of the first and last name doesn't work. I get a runtime error 5 - Invalid procedure call or argument. Please let me know what I am missing. Also I have no intellisence in VB. What do I need to do to get the intellisence working. Below is my C# test code namespace MrdcToFastCom { public class Person : MrdcToFastCom.IPerson { public string FirstName { get; set; } public string LastName { get; set; } } public class ComTester : MrdcToFastCom.IComTester { public string EchoString(string s) { return ("Echo: " + s); } public string Hello() { return "Hello"; } public string EchoPerson(ref Person p) { return string.Format("{0} {1}", p.FirstName, p.LastName); } } } and VB6 call Private Sub btnClickMe_Click() Dim ct Set ct = New MrdcToFastCom.ComTester Dim p Set p = New MrdcToFastCom.Person p.FirstName = "Joe" p.LastName = "Test" Dim s s = ct.EchoPerson(p) 'Error on this line tbx1.Text = s End Sub

  • Binding WPF ComboBox in XAML - Why is it Empty?

    - by mdiehl13
    I am trying to learn how to bind my simple database (.sdf) to a combobox. I created a dataset with my tables in it. I then dragged a table from the DataSource onto my control.

  • ifstream Open function not working

    - by Dave Swersky
    I've been all over the ifstream questions here on SO and I'm still having trouble reading a simple text file. I'm working with Visual Studio 2008. Here's my code: // CPPFileIO.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <fstream> #include <conio.h> #include <iostream> #include <string> using namespace std; int _tmain(int argc, _TCHAR* argv[]) { ifstream infile; infile.open("input.txt", ifstream::in); if (infile.is_open()) { while (infile.good()) cout << (char) infile.get(); } else { cout << "Unable to open file."; } infile.close(); _getch(); return 0; } I have confirmed that the input.txt file is in the correct "working directory" by checking the value of argv[0]. The Open method just won't work. I'm also having trouble debugging- should I not be able to set a watch on "infile.good()" or "infile.is_open()"? I keep getting "Error: member function not present." EDIT: Updated code listing with full code from .CPP file. UPDATE: The file was NOT in the Current Working Directory. This is the directory where the project file is located. Moved it there and it works when debugging in VS.NET.

    I'm doing my first ASP.NET MVC2 project and I can't get past the "A potentially dangerous Request.Form value was detected..." error when trying to submit a form. I've done this in MVC1 using the ValidateInputAttribute and I've read about the breaking change in .NET 4 that requires setting the request validation mode in the web.config. Basically I'm doing exactly what is outlined in this thread: http://stackoverflow.com/questions/2019843/a-potentially-dangerous-request-form-value-in-mvc-2-asp-net-4-0.

  • Error displaying a WinForm in Design mode with a custom control on it.

    - by George
    I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run. It may have something to do with namespaces. The original namespace was simply "Design" and this was ambiguous and conflicting so i decided to rename it. I think that's when my problems began. To prevent possible data loss before loading the designer, the following errors must be resolved: 2 Errors Ignore and Continue Why am I seeing this page?

  • Perl, module export symbol

    - by Mike
    I'm having trouble understanding how to export a package symbol to a namespace. I've followed the documentation almost identically, but it seems to not know about any of the exporting symbols. mod.pm #!/usr/bin/perl package mod; use strict; use warnings; require Exporter; @ISA = qw(Exporter); @EXPORT=qw($a); our $a=(1); 1; test.pl $ cat test.pl #!/usr/bin/perl use mod; print($a); This is the result of running it $ ./test.pl Global symbol "@ISA" requires explicit package name at mod.pm line 10. Global symbol "@EXPORT" requires explicit package name at mod.pm line 11. Compilation failed in require at ./test.pl line 3. BEGIN failed--compilation aborted at ./test.pl line 3. $ perl -version This is perl, v5.8.4 built for sun4-solaris-64int

  • Trying to get WCF client to work with wss 1.0 username token security

    - by darius murauskas
    I am trying to use a WCF client to call a third party web service. The web Service usses username token authentication WSS-Security 1.0 Soap Message Security Here is a sample soap authentication header for what the web service expects <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <wsse:Security soap:mustUnderstand="1"> <wsse:UsernameToken namespaces> <wsse:Username>username</wsse:Username> <wsse:Password Type="type info">password</wsse:Password> <wsse:Nonce>nonce</wsse:Nonce> <wsu:Created>date created</wsu:Created> </wsse:UsernameToken> <wsse:Security> </soap:Header> <soap:Body> <WebServiceMethodName xmlns="Web Service Namespace" /> I configured the client to the following way <basicHttpBinding> <binding name="Binding1"> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="Basic"/> </security> </basicHttpBinding> but recieved an error that stating that the nonce and datecreated attributes were missing in the header. Does anyone know how to configure a WCF client to work with WSS-Security 1.0 Soap Message Security username token authentication?

  • vimscript: calling dictionary functions with call()

    - by intuited
    I'm hoping to call a "static" dictionary function using call(). By "static" I mean that the keyword 'dict' is not used in the function's definition. I use this nomenclature in the hopes that the effect of this keyword is to declare a static member function as is possible in java/C++/etc, ie to put the function name in the class namespace but allow it to be called without referencing an object. However this doesn't seem to work. For example: " Setup: let testdict = { } funct! testdict.funct() echo "called" endfunct " Tests: " Following each line is an indented comment " containing its output in message land, ie what was echoed. call testdict.funct() " called echo testdict.funct " 667 echo string(testdict.funct) " function('667') echo function('667') " E475: Invalid argument: 667 echo function('testdict.funct') " testdict.funct call call(testdict.funct, [ ]) " E725: Calling dict function without Dictionary: 667 " Same deal if there's an intermediate variable involved. let TestdictDotFunct = testdict.funct echo TestdictDotFunct " 667 echo string(TestdictDotFunct) " function('667') call TestdictDotFunct() " E725: Calling dict function without Dictionary: 667 From the help topic E725: It is also possible to add a function without the "dict" attribute as a Funcref to a Dictionary, but the "self" variable is not available then. So logic would seem to indicate that if "self" is not available, then it should be possible to call the function referenced by the Funcref without a Dictionary. However this doesn't seem to be the case. Am I missing something?

  • EF 4.0 : Save Changes Retry Logic

    - by BGR
    Hi, I would like to implement an application wide retry system for all entity SaveChanges method calls. Technologies: Entity framework 4.0 .Net 4.0 namespace Sample.Data.Store.Entities { public partial class StoreDB { public override int SaveChanges(System.Data.Objects.SaveOptions options) { for (Int32 attempt = 1; ; ) { try { return base.SaveChanges(options); } catch (SqlException sqlException) { // Increment Trys attempt++; // Find Maximum Trys Int32 maxRetryCount = 5; // Throw Error if we have reach the maximum number of retries if (attempt == maxRetryCount) throw; // Determine if we should retry or abort. if (!RetryLitmus(sqlException)) throw; else Thread.Sleep(ConnectionRetryWaitSeconds(attempt)); } } } static Int32 ConnectionRetryWaitSeconds(Int32 attempt) { Int32 connectionRetryWaitSeconds = 2000; // Backoff Throttling connectionRetryWaitSeconds = connectionRetryWaitSeconds * (Int32)Math.Pow(2, attempt); return (connectionRetryWaitSeconds); } /// <summary> /// Determine from the exception if the execution /// of the connection should Be attempted again /// </summary> /// <param name="exception">Generic Exception</param> /// <returns>True if a a retry is needed, false if not</returns> static Boolean RetryLitmus(SqlException sqlException) { switch (sqlException.Number) { // The service has encountered an error // processing your request. Please try again. // Error code %d. case 40197: // The service is currently busy. Retry // the request after 10 seconds. Code: %d. case 40501: //A transport-level error has occurred when // receiving results from the server. (provider: // TCP Provider, error: 0 - An established connection // was aborted by the software in your host machine.) case 10053: return (true); } return (false); } } } The problem: How can I run the StoreDB.SaveChanges to retry on a new DB context after an error occured? Something simular to Detach/Attach might come in handy. Thanks in advance! Bart

  • How to parse kanji numeric characters using ICU?

    - by Aki
    I'm writing a function using ICU to parse an Unicode string which consists of kanji numeric character(s) and want to return the integer value of the string. "?" = 5 "???" = 31 "???????" = 5972 I'm setting the locale to Locale::getJapan() and using the NumberFormat::parse() to parse the character string. However, whenever I pass it any Kanji characters, the parse() method is returning U_INVALID_FORMAT_ERROR. Does anyone know if ICU supports Kanji character strings in the NumberFormat::parse() method? I was hoping that since I'm setting the Locale to Japanese that it would be able to parse Kanji numeric values. Thanks! #include <iostream> #include <unicode/numfmt.h> using namespace std; int main(int argc, char **argv) { const Locale &jaLocale = Locale::getJapan(); UErrorCode status = U_ZERO_ERROR; NumberFormat *nf = NumberFormat::createInstance(jaLocale, status); UChar number[] = {0x4E94}; // Character for '5' in Japanese '?' UnicodeString numStr(number); Formattable formattable; nf->parse(numStr, formattable, status); if (U_FAILURE(status)) { cout << "error parsing as number: " << u_errorName(status) << endl; return(1); } cout << "long value: " << formattable.getLong() << endl; }
