  • Drupal Migration Problem

    - by Gok Demir
    After migrating my Drupal (6.16) installation from shared hosting to Linode VPS (Ubunto 10.04 32 bit). Whenever I click a URL it shows only the homepage. I put ?q=user at the end of the URL to login as an admin. When I logged in it is the same. I couldn't navigate to any URL. It shows only homepage. I forgot to clean Drupal cache before migration. Is it because of this? I couldn't navigate to Administer Site configuration Performance to clean cache, nothing works.

Obviously, I use _val in wrong way, but I do not know how to do this correctly. Help, please! :) P.S. And sorry for my terrible English…

  • Content display problems when using Suckerfish menus with 960.gs and IE

    - by Cedar Jensen
    I'm using 960.gs layout and when I add the suckerfish menu as part of the content to one of the grids, the contents of adjacent siblings bleed through the menu in all versions of IE. In the listed html below, the text from 'belowFoldSection' will appear through the menu when it is visible and has enough items to make it span over 2nd section. However, the contents of 'introSummary' will be underneath the menu, as expected. I've set the z-index for #nav and #nav ul in my css and this of course makes it work in FF, Chrome and Safari, but not in IE (because IE incorrectly assigns child elements its own z-index). If I change the .grid_nn class 'position' attribute (set by default in the 960 template) from 'relative' to absolute, this fixes it in IE. However, it is my understanding that I don't want the child elements of the 'container_12' to be taken out of the flow of the document and want them positioned relative to the .container_12's starting point. (Changing the attribute to absolute causes other general layout problems) Can anyone suggest a work-around? My html: <div class="container_12"> <!--First section where menu lives--> <div class="grid_12" id="mainSection"> <div class="grid_4 alpha" id="intro"> <p>Start of menu here</p> <div id="subMenu"> <ul id="nav"> <li><a href="#">Item 1</a> <ul> <li><a href="#">Burrowing gobies</a></li> <li><a href="#">Dartfishes</a></li> <li><a href="#">Eellike gobies</a></li> <!--10 more for longer list --> </ul> </li> <li><a href="#">Item 2</a> <ul> <li><a href="#">Remoras</a></li> <li><a href="#">Tilefishes</a></li> <!--10 more for longer list --> </ul> </li> <li><a href="#">Item 3</a> <ul> <li><a href="#">Climbing perches</a></li> <li><a href="#">Labyrinthfishes</a></li> <li><a href="#">Kissing gouramis</a></li> <!--10 more for longer list --> </ul> </li> </ul> <div id="introSummary"> <h1>PERCIFORMES!

  • DirectShow: Video-Preview and Image (with working code)

    - by xsl
    Questions / Issues If someone can recommend me a good free hosting site I can provide the whole project file. As mentioned in the text below the TakePicture() method is not working properly on the HTC HD 2 device. It would be nice if someone could look at the code below and tell me if it is right or wrong what I'm doing. Introduction I recently asked a question about displaying a video preview, taking camera image and rotating a video stream with DirectShow. The tricky thing about the topic is, that it's very hard to find good examples and the documentation and the framework itself is very hard to understand for someone who is new to windows programming and C++ in general. Nevertheless I managed to create a class that implements most of this features and probably works with most mobile devices. Probably because the DirectShow implementation depends a lot on the device itself. I could only test it with the HTC HD and HTC HD2, which are known as quite incompatible. HTC HD Working: Video preview, writing photo to file Not working: Set video resolution (CRASH), set photo resolution (LOW quality) HTC HD 2 Working: Set video resolution, set photo resolution Problematic: Video Preview rotated Not working: Writing photo to file To make it easier for others by providing a working example, I decided to share everything I have got so far below. I removed all of the error handling for the sake of simplicity. As far as documentation goes, I can recommend you to read the MSDN documentation, after that the code below is pretty straight forward. void Camera::Init() { CreateComObjects(); _captureGraphBuilder->SetFiltergraph(_filterGraph); InitializeVideoFilter(); InitializeStillImageFilter(); } Dipslay a video preview (working with any tested handheld): void Camera::DisplayVideoPreview(HWND windowHandle) { IVideoWindow *_vidWin; _filterGraph->QueryInterface(IID_IMediaControl,(void **) &_mediaControl); _filterGraph->QueryInterface(IID_IVideoWindow, (void **) &_vidWin); _videoCaptureFilter->QueryInterface(IID_IAMVideoControl, (void**) &_videoControl); _captureGraphBuilder->RenderStream(&PIN_CATEGORY_PREVIEW, &MEDIATYPE_Video, _videoCaptureFilter, NULL, NULL); CRect rect; long width, height; GetClientRect(windowHandle, &rect); _vidWin->put_Owner((OAHWND)windowHandle); _vidWin->put_WindowStyle(WS_CHILD | WS_CLIPSIBLINGS); _vidWin->get_Width(&width); _vidWin->get_Height(&height); height = rect.Height(); _vidWin->put_Height(height); _vidWin->put_Width(rect.Width()); _vidWin->SetWindowPosition(0,0, rect.Width(), height); _mediaControl->Run(); } HTC HD2: If set SetPhotoResolution() is called FindPin will return E_FAIL. If not, it will create a file full of null bytes. HTC HD: Works void Camera::TakePicture(WCHAR *fileName) { CComPtr<IFileSinkFilter> fileSink; CComPtr<IPin> stillPin; CComPtr<IUnknown> unknownCaptureFilter; CComPtr<IAMVideoControl> videoControl; _imageSinkFilter.QueryInterface(&fileSink); fileSink->SetFileName(fileName, NULL); _videoCaptureFilter.QueryInterface(&unknownCaptureFilter); _captureGraphBuilder->FindPin(unknownCaptureFilter, PINDIR_OUTPUT, &PIN_CATEGORY_STILL, &MEDIATYPE_Video, FALSE, 0, &stillPin); _videoCaptureFilter.QueryInterface(&videoControl); videoControl->SetMode(stillPin, VideoControlFlag_Trigger); } Set resolution: Works great on HTC HD2. HTC HD won't allow SetVideoResolution() and only offers one low resolution photo resolution: void Camera::SetVideoResolution(int width, int height) { SetResolution(true, width, height); } void Camera::SetPhotoResolution(int width, int height) { SetResolution(false, width, height); } void Camera::SetResolution(bool video, int width, int height) { IAMStreamConfig *config; config = NULL; if (video) { _captureGraphBuilder->FindInterface(&PIN_CATEGORY_PREVIEW, &MEDIATYPE_Video, _videoCaptureFilter, IID_IAMStreamConfig, (void**) &config); } else { _captureGraphBuilder->FindInterface(&PIN_CATEGORY_STILL, &MEDIATYPE_Video, _videoCaptureFilter, IID_IAMStreamConfig, (void**) &config); } int resolutions, size; VIDEO_STREAM_CONFIG_CAPS caps; config->GetNumberOfCapabilities(&resolutions, &size); for (int i = 0; i < resolutions; i++) { AM_MEDIA_TYPE *mediaType; if (config->GetStreamCaps(i, &mediaType, reinterpret_cast<BYTE*>(&caps)) == S_OK ) { int maxWidth = caps.MaxOutputSize.cx; int maxHeigth = caps.MaxOutputSize.cy; if(maxWidth == width && maxHeigth == height) { VIDEOINFOHEADER *info = reinterpret_cast<VIDEOINFOHEADER*>(mediaType->pbFormat); info->bmiHeader.biWidth = maxWidth; info->bmiHeader.biHeight = maxHeigth; info->bmiHeader.biSizeImage = DIBSIZE(info->bmiHeader); config->SetFormat(mediaType); DeleteMediaType(mediaType); break; } DeleteMediaType(mediaType); } } } Other methods used to build the filter graph and create the COM objects: void Camera::CreateComObjects() { CoInitialize(NULL); CoCreateInstance(CLSID_CaptureGraphBuilder, NULL, CLSCTX_INPROC_SERVER, IID_ICaptureGraphBuilder2, (void **) &_captureGraphBuilder); CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void **) &_filterGraph); CoCreateInstance(CLSID_VideoCapture, NULL, CLSCTX_INPROC, IID_IBaseFilter, (void**) &_videoCaptureFilter); CoCreateInstance(CLSID_IMGSinkFilter, NULL, CLSCTX_INPROC, IID_IBaseFilter, (void**) &_imageSinkFilter); } void Camera::InitializeVideoFilter() { _videoCaptureFilter->QueryInterface(&_propertyBag); wchar_t deviceName[MAX_PATH] = L"\0"; GetDeviceName(deviceName); CComVariant comName = deviceName; CPropertyBag propertyBag; propertyBag.Write(L"VCapName", &comName); _propertyBag->Load(&propertyBag, NULL); _filterGraph->AddFilter(_videoCaptureFilter, L"Video Capture Filter Source"); } void Camera::InitializeStillImageFilter() { _filterGraph->AddFilter(_imageSinkFilter, L"Still image filter"); _captureGraphBuilder->RenderStream(&PIN_CATEGORY_STILL, &MEDIATYPE_Video, _videoCaptureFilter, NULL, _imageSinkFilter); } void Camera::GetDeviceName(WCHAR *deviceName) { HRESULT hr = S_OK; HANDLE handle = NULL; DEVMGR_DEVICE_INFORMATION di; GUID guidCamera = { 0xCB998A05, 0x122C, 0x4166, 0x84, 0x6A, 0x93, 0x3E, 0x4D, 0x7E, 0x3C, 0x86 }; di.dwSize = sizeof(di); handle = FindFirstDevice(DeviceSearchByGuid, &guidCamera, &di); StringCchCopy(deviceName, MAX_PATH, di.szLegacyName); } Full header file: #ifndef __CAMERA_H__ #define __CAMERA_H__ class Camera { public: void Init(); void DisplayVideoPreview(HWND windowHandle); void TakePicture(WCHAR *fileName); void SetVideoResolution(int width, int height); void SetPhotoResolution(int width, int height); private: CComPtr<ICaptureGraphBuilder2> _captureGraphBuilder; CComPtr<IGraphBuilder> _filterGraph; CComPtr<IBaseFilter> _videoCaptureFilter; CComPtr<IPersistPropertyBag> _propertyBag; CComPtr<IMediaControl> _mediaControl; CComPtr<IAMVideoControl> _videoControl; CComPtr<IBaseFilter> _imageSinkFilter; void GetDeviceName(WCHAR *deviceName); void InitializeVideoFilter(); void InitializeStillImageFilter(); void CreateComObjects(); void SetResolution(bool video, int width, int height); }; #endif

  • CheckBox ListView SelectedValues DependencyProperty Binding

    - by Ristogod
    I am writing a custom control that is a ListView that has a CheckBox on each item in the ListView to indicate that item is Selected. I was able to do so with the following XAML. <ListView x:Class="CheckedListViewSample.CheckBoxListView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d"> <ListView.Style> <Style TargetType="{x:Type ListView}"> <Setter Property="SelectionMode" Value="Multiple" /> <Style.Resources> <Style TargetType="ListViewItem"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListViewItem"> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True"> <CheckBox IsChecked="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}"> <CheckBox.Content> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </CheckBox.Content> </CheckBox> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Style.Resources> </Style> </ListView.Style> </ListView> I however am trying to attempt one more feature. The ListView has a SelectedItems DependencyProperty that returns a collection of the Items that are checked. However, I need to implement a SelectedValues DependencyProperty. I also am implementing a SelectedValuesPath DependencyProperty. By using the SelectedValuesPath, I indicate the path where the values are found for each selected item. So if my items have an ID property, I can specify using the SelectedValuesPath property "ID". The SelectedValues property would then return a collection of ID values. I have this working also using this code in the code-behind: using System.Windows; using System.Windows.Controls; using System.ComponentModel; using System.Collections; using System.Collections.Generic; namespace CheckedListViewSample { /// <summary> /// Interaction logic for CheckBoxListView.xaml /// </summary> public partial class CheckBoxListView : ListView { public static DependencyProperty SelectedValuesPathProperty = DependencyProperty.Register("SelectedValuesPath", typeof(string), typeof(CheckBoxListView), new PropertyMetadata(string.Empty, null)); public static DependencyProperty SelectedValuesProperty = DependencyProperty.Register("SelectedValues", typeof(IList), typeof(CheckBoxListView), new PropertyMetadata(new List<object>(), null)); [Category("Appearance")] [Localizability(LocalizationCategory.NeverLocalize)] [Bindable(true)] public string SelectedValuesPath { get { return ((string)(base.GetValue(CheckBoxListView.SelectedValuesPathProperty))); } set { base.SetValue(CheckBoxListView.SelectedValuesPathProperty, value); } } [Bindable(true)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] [Category("Appearance")] public IList SelectedValues { get { return ((IList)(base.GetValue(CheckBoxListView.SelectedValuesPathProperty))); } set { base.SetValue(CheckBoxListView.SelectedValuesPathProperty, value); } } public CheckBoxListView() : base() { InitializeComponent(); base.SelectionChanged += new SelectionChangedEventHandler(CheckBoxListView_SelectionChanged); } private void CheckBoxListView_SelectionChanged(object sender, SelectionChangedEventArgs e) { List<object> values = new List<object>(); foreach (var item in SelectedItems) { if (string.IsNullOrWhiteSpace(SelectedValuesPath)) { values.Add(item); } else { try { values.Add(item.GetType().GetProperty(SelectedValuesPath).GetValue(item, null)); } catch { } } } base.SetValue(CheckBoxListView.SelectedValuesProperty, values); e.Handled = true; } } } My problem is that my binding only works one way right now. I'm having trouble trying to figure out how to implement my SelectedValues DependencyProperty so that I could Bind a Collection of values to it, and when the control is loaded, the CheckBoxes are checked with items that have values that correspond to the SelectedValues. I've considered using the PropertyChangedCallBack event, but can't quite figure out how I could write that to achieve my goal. I'm also unsure of how I find the correct ListViewItem to set it as Selected. And lastly, if I can find the ListViewItem and set it to be Selected, won't that fire my SelectionChanged event each time I set a ListViewItem to be Selected?

  • Parsing "true" and "false" using Boost.Spirit.Lex and Boost.Spirit.Qi

    - by Andrew Ross
    As the first stage of a larger grammar using Boost.Spirit I'm trying to parse "true" and "false" to produce the corresponding bool values, true and false. I'm using Spirit.Lex to tokenize the input and have a working implementation for integer and floating point literals (including those expressed in a relaxed scientific notation), exposing int and float attributes. Token definitions #include <boost/spirit/include/lex_lexertl.hpp> namespace lex = boost::spirit::lex; typedef boost::mpl::vector<int, float, bool> token_value_type; template <typename Lexer> struct basic_literal_tokens : lex::lexer<Lexer> { basic_literal_tokens() { this->self.add_pattern("INT", "[-+]?[0-9]+"); int_literal = "{INT}"; // To be lexed as a float a numeric literal must have a decimal point // or include an exponent, otherwise it will be considered an integer. float_literal = "{INT}(((\\.[0-9]+)([eE]{INT})?)|([eE]{INT}))"; literal_true = "true"; literal_false = "false"; this->self = literal_true | literal_false | float_literal | int_literal; } lex::token_def<int> int_literal; lex::token_def<float> float_literal; lex::token_def<bool> literal_true, literal_false; }; Testing parsing of float literals My real implementation uses Boost.Test, but this is a self-contained example. #include <string> #include <iostream> #include <cmath> #include <cstdlib> #include <limits> bool parse_and_check_float(std::string const & input, float expected) { typedef std::string::const_iterator base_iterator_type; typedef lex::lexertl::token<base_iterator_type, token_value_type > token_type; typedef lex::lexertl::lexer<token_type> lexer_type; basic_literal_tokens<lexer_type> basic_literal_lexer; base_iterator_type input_iter(input.begin()); float actual; bool result = lex::tokenize_and_parse(input_iter, input.end(), basic_literal_lexer, basic_literal_lexer.float_literal, actual); return result && std::abs(expected - actual) < std::numeric_limits<float>::epsilon(); } int main(int argc, char *argv[]) { if (parse_and_check_float("+31.4e-1", 3.14)) { return EXIT_SUCCESS; } else { return EXIT_FAILURE; } } Parsing "true" and "false" My problem is when trying to parse "true" and "false". This is the test code I'm using (after removing the Boost.Test parts): bool parse_and_check_bool(std::string const & input, bool expected) { typedef std::string::const_iterator base_iterator_type; typedef lex::lexertl::token<base_iterator_type, token_value_type > token_type; typedef lex::lexertl::lexer<token_type> lexer_type; basic_literal_tokens<lexer_type> basic_literal_lexer; base_iterator_type input_iter(input.begin()); bool actual; lex::token_def<bool> parser = expected ? basic_literal_lexer.literal_true : basic_literal_lexer.literal_false; bool result = lex::tokenize_and_parse(input_iter, input.end(), basic_literal_lexer, parser, actual); return result && actual == expected; } but compilation fails with: boost/spirit/home/qi/detail/assign_to.hpp: In function ‘void boost::spirit::traits::assign_to(const Iterator&, const Iterator&, Attribute&) [with Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, Attribute = bool]’: boost/spirit/home/lex/lexer/lexertl/token.hpp:434: instantiated from ‘static void boost::spirit::traits::assign_to_attribute_from_value<Attribute, boost::spirit::lex::lexertl::token<Iterator, AttributeTypes, HasState>, void>::call(const boost::spirit::lex::lexertl::token<Iterator, AttributeTypes, HasState>&, Attribute&) [with Attribute = bool, Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, AttributeTypes = boost::mpl::vector<int, float, bool, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, HasState = mpl_::bool_<true>]’ ... backtrace of instantiation points .... boost/spirit/home/qi/detail/assign_to.hpp:79: error: no matching function for call to ‘boost::spirit::traits::assign_to_attribute_from_iterators<bool, __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, void>::call(const __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >&, const __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >&, bool&)’ boost/spirit/home/qi/detail/construct.hpp:64: note: candidates are: static void boost::spirit::traits::assign_to_attribute_from_iterators<bool, Iterator, void>::call(const Iterator&, const Iterator&, char&) [with Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >] My interpretation of this is that Spirit.Qi doesn't know how to convert a string to a bool - surely that's not the case? Has anyone else done this before? If so, how?

  • The remote server returned an error: (400) Bad Request - uploading less 2MB file size?

    - by fiberOptics
    The file succeed to upload when it is 2KB or lower in size. The main reason why I use streaming is to be able to upload file up to at least 1 GB. But when I try to upload file with less 1MB size, I get bad request. It is my first time to deal with downloading and uploading process, so I can't easily find the cause of error.

  • Two-way databinding of a custom templated asp.net control

    - by Jason
    I hate long code snippets and I'm sorry about this one, but it turns out that this asp.net stuff can't get much shorter and it's so specific that I haven't been able to generalize it without a full code listing. I just want simple two-way, declarative, edit-only databinding to a single instance of an object. Not a list of objects of a type with a bunch of NotImplementedExceptions for Add, Delete, and Select, but just a single view-state persisted object. This is certainly something that can be done but I've struggled with an implementation for years. This newest, closest implementation was inspired by this article from 4-Guys-From-Rolla. Unfortunately, after implementing, I'm getting the following error and I don't know what I'm missing: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. If I don't use Bind(), and only use Eval() functionality, it works. In that way, the error is especially confusing. Update: Actually, using Eval() does NOT work, but using <%# Container.SampleString %> works. However, Eval("SampleString") gives the same error. That leads me back to this article I found earlier but had discarded. Now I believe it might be related, though I haven't cracked it yet ... Here's the simplified codeset that still produces the error: using System.ComponentModel; namespace System.Web.UI.WebControls.Special { public class SampleFormData { public string SampleString = "Sample String Data"; public int SampleInt = -1; } [ToolboxItem(false)] public class SampleSpecificFormDataContainer : DataBoundControl, INamingContainer { SampleSpecificEntryForm entryForm; internal SampleSpecificEntryForm EntryForm { get { return entryForm; } } [Bindable(true), Category("Data")] public string SampleString { get { return entryForm.FormData.SampleString; } set { entryForm.FormData.SampleString = value; } } [Bindable(true), Category("Data")] public int SampleInt { get { return entryForm.FormData.SampleInt; } set { entryForm.FormData.SampleInt = value; } } internal SampleSpecificFormDataContainer(SampleSpecificEntryForm entryForm) { this.entryForm = entryForm; } } public class SampleSpecificEntryForm : WebControl, INamingContainer { #region Template private IBindableTemplate formTemplate = null; [Browsable(false), DefaultValue(null), TemplateContainer(typeof(SampleSpecificFormDataContainer), ComponentModel.BindingDirection.TwoWay), PersistenceMode(PersistenceMode.InnerProperty)] public virtual IBindableTemplate FormTemplate { get { return formTemplate; } set { formTemplate = value; } } #endregion #region Viewstate SampleFormData FormDataVS { get { return (ViewState["FormData"] as SampleFormData) ?? new SampleFormData(); } set { ViewState["FormData"] = value; SaveViewState(); } } #endregion public override ControlCollection Controls { get { EnsureChildControls(); return base.Controls; } } private SampleSpecificFormDataContainer formDataContainer = null; [Browsable(false), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] public SampleSpecificFormDataContainer FormDataContainer { get { EnsureChildControls(); return formDataContainer; } } [Bindable(true), Browsable(false)] public SampleFormData FormData { get { return FormDataVS; } set { FormDataVS = value; } } protected override void CreateChildControls() { if (!this.ChildControlsCreated) { Controls.Clear(); formDataContainer = new SampleSpecificFormDataContainer(this); Controls.Add(formDataContainer); FormTemplate.InstantiateIn(formDataContainer); this.ChildControlsCreated = true; } } public override void DataBind() { CreateChildControls(); base.DataBind(); } } } With an ASP.NET page the following: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default2.aspx.cs" Inherits="EntryFormTest._Default2" EnableEventValidation="false" %> <%@ Register Assembly="EntryForm" Namespace="System.Web.UI.WebControls.Special" TagPrefix="cc1" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <cc1:SampleSpecificEntryForm ID="EntryForm1" runat="server"> <FormTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("SampleString") %>'></asp:TextBox><br /> <h3>(<%# Container.SampleString %>)</h3><br /> <asp:Button ID="Button1" runat="server" Text="Button" /> </FormTemplate> </cc1:SampleSpecificEntryForm> </asp:Content> Default2.aspx.cs using System; namespace EntryFormTest { public partial class _Default2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { EntryForm1.DataBind(); } } } Thanks for any help!

  • spring web application context is not loaded from jar file in WEB-INF/lib when running tomcat in eclipse

    - by Remy J
    I am experimenting with spring, maven, and eclipse but stumbling on a weird issue. I am running Eclipse Helios SR1 with the STS (Spring tools suite) plugin which includes the Maven plugin also. What i want to achieve is a spring mvc webapp which uses an application context loaded from a local application context xml file, but also from other application contexts in jar files dependencies included in WEB-INF/lib. What i'd ultimately like to do is have my persistence layer separated in its own jar file but containing its own spring context files with persistence specific configuration (e.g a jpa entityManagerFactory for example). So to experiment with loading resources from jar dependencies, i created a simple maven project from eclipse, which defines an applicationContext.xml file in src/main/resources Inside, i define a bean <bean id="mybean" class="org.test.MyClass" /> and create the class in the org.test package I run mvn-install from eclipse, which generates me a jar file containing my class and the applicationContext.xml file: testproj.jar |_META-INF |_org |_test |_MyClass.class |_applicationContext.xml I then create a spring mvc project from the Spring template projects provided by STS. I have configured an instance of Tomcat 7.0.8 , and also an instance of springSource tc Server within eclipse. Deploying the newly created project on both servers works without problem. I then add my previous project as a maven dependency of the mvc project. the jar file is correctly added in the Maven Dependencies of the project. In the web.xml that is generated, i now want to load the applicationContext.xml from the jar file as well as the existing one generated for the project. My web.xml now looks like this: org.springframework.web.context.ContextLoaderListener <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:applicationContext.xml, /WEB-INF/spring/appServlet/servlet-context.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> Also, in my servlet-context.xml, i have the following: <context:component-scan base-package="org.test" /> <context:component-scan base-package="org.remy.mvc" /> to load classes from the jar spring context (org.test) and to load controllers from the mvc app context. I also change one of my controllers in org.remy.mvc to autowire MyClass to verify that loading the context has worked as intended. public class MyController { @Autowired private MyClass myClass; public void setMyClass(MyClass myClass) { this.myClass = myClass; } public MyClass getMyClass() { return myClass; } [...] } Now this is the weird bit: If i deploy the spring mvc web on my tomcat instance inside eclipse (run on server...) I get the following error : org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': Initialization of bean failed;

  • Authoritative sources about Database vs. Flatfile decision

    - by FastAl
    <tldr>looking for a reference to a book or other undeniably authoritative source that gives reasons when you should choose a database vs. when you should choose other storage methods. I have provided an un-authoritative list of reasons about 2/3 of the way down this post.</tldr> I have a situation at my company where a database is being used where it would be better to use another solution (in this case, an auto-generated piece of source code that contains a static lookup table, searched by binary sort). Normally, a database would be an OK solution even though the problem does not require a database, e.g, none of the elements of ACID are needed, as it is read-only data, updated about every 3-5 years (also requiring other sourcecode changes), and fits in memory, and can be keyed into via binary search (a tad faster than db, but speed is not an issue). The problem is that this code runs on our enterprise server, but is shared with several PC platforms (some disconnected, some use a central DB, etc.), and parts of it are managed by multiple programming units, parts by the DBAs, parts even by mathematicians in another department, etc. These hit their own platform’s version of their databases (containing their own copy of the static data). What happens is that every implementation, every little change, something different goes wrong. There are many other issues as well. I can’t even use a flatfile, because one mode of running on our enterprise server does not have permission to read files (only databases, and of course, its own literal storage, e.g., in-source table). Of course, other parts of the system use databases in proper, less obscure manners; there is no problem with those parts. So why don’t we just change it? I don’t have administrative ability to force a change. But I’m affected because sometimes I have to help fix the problems, but mostly because it causes outages and tons of extra IT time by other programmers and d*mmit that makes me mad! The reason neither management, nor the designers of the system, can see the problem is that they propose a solution that won’t work: increase communication; implement more safeguards and standards; etc. But every time, in a different part of the already-pared-down but still multi-step processes, a few different diligent, hard-working, top performing IT personnel make a unique subtle error that causes it to fail, sometimes after the last round of testing! And in general these are not single-person failures, but understandable miscommunications. And communication at our company is actually better than most. People just don't think that's the case because they haven't dug into the matter. However, I have it on very good word from somebody with extensive formal study of sociology and psychology that the relatively small amount of less-than-proper database usage in this gigantic cross-platform multi-source, multi-language project is bureaucratically un-maintainable. Impossible. No chance. At least with Human Beings in the loop, and it can’t be automated. In addition, the management and developers who could change this, though intelligent and capable, don’t understand the rigidity of this ‘how humans are’ issue, and are not convincible on the matter. The reason putting the static data in sourcecode will solve the problem is, although the solution is less sexy than a database, it would function with no technical drawbacks; and since the sharing of sourcecode already works very well, you basically erase any database-related effort from this section of the project, along with all the drawbacks of it that are causing problems. OK, that’s the background, for the curious. I won’t be able to convince management that this is an unfixable sociological problem, and that the real solution is coding around these limits of human nature, just as you would code around a bug in a 3rd party component that you can’t change. So what I have to do is exploit the unsuitableness of the database solution, and not do it using logic, but rather authority. I am aware of many reasons, and posts on this site giving reasons for one over the other; I’m not looking for lists of reasons like these (although you can add a comment if I've miss a doozy): WHY USE A DATABASE? instead of flatfile/other DB vs. file: if you need... Random Read / Transparent search optimization Advanced / varied / customizable Searching and sorting capabilities Transaction/rollback Locks, semaphores Concurrency control / Shared users Security 1-many/m-m is easier Easy modification Scalability Load Balancing Random updates / inserts / deletes Advanced query Administrative control of design, etc. SQL / learning curve Debugging / Logging Centralized / Live Backup capabilities Cached queries / dvlp & cache execution plans Interleaved update/read Referential integrity, avoid redundant/missing/corrupt/out-of-sync data Reporting (from on olap or oltp db) / turnkey generation tools [Disadvantages:] Important to get right the first time - professional design - but only b/c it's meant to last s/w & h/w cost Usu. over a network, speed issue (best vs. best design vs. local=even then a separate process req's marshalling/netwk layers/inter-p comm) indicies and query processing can stand in the way of simple processing (vs. flatfile) WHY USE FLATFILE: If you only need... Sequential Row processing only Limited usage append only (no reading, no master key/update) Only Update the record you're reading (fixed length recs only) Too big to fit into memory If Local disk / read-ahead network connection Portability / small system Email / cut & Paste / store as document by novice - simple format Low design learning curve but high cost later WHY USE IN-MEMORY/TABLE (tables, arrays, etc.): if you need... Processing a single db/ff record that was imported Known size of data Static data if hardcoding the table Narrow, unchanging use (e.g., one program or proc) -includes a class that will be shared, but encapsulates its data manipulation Extreme speed needed / high transaction frequency Random access - but search is dependent on implementation Following are some other posts about the topic: http://stackoverflow.com/questions/1499239/database-vs-flat-text-file-what-are-some-technical-reasons-for-choosing-one-over http://stackoverflow.com/questions/332825/are-flat-file-databases-any-good http://stackoverflow.com/questions/2356851/database-vs-flat-files http://stackoverflow.com/questions/514455/databases-vs-plain-text/514530 What I’d like to know is if anybody could recommend a hard, authoritative source containing these reasons. I’m looking for a paper book I can buy, or a reputable website with whitepapers about the issue (e.g., Microsoft, IBM), not counting the user-generated content on those sites. This will have a greater change to elicit a change that I’m looking for: less wasted programmer time, and more reliable programs. Thanks very much for your help. You win a prize for reading such a large post!

  • Ignoring focusLost(), SWT.Verify, or other SWT listeners in Java code.

    - by Zoot
    Outside of the actual SWT listener, is there any way to ignore a listener via code? For example, I have a java program that implements SWT Text Widgets, and the widgets have: SWT.Verify listeners to filter out unwanted text input. ModifyListeners to wait for the correct number of valid input characters and automatically set focus (using setFocus())to the next valid field, skipping the other text widgets in the tab order. focusLost(FocusEvent) FocusListeners that wait for the loss of focus from the text widget to perform additional input verification and execute an SQL query based on the user input. The issue I run into is clearing the text widgets. One of the widgets has the format "####-##" (Four Numbers, a hyphen, then two numbers) and I have implemented this listener, which is a modified version of SWT Snippet Snippet179. The initial text for this text widget is " - " to provide visual feedback to the user as to the expected format. Only numbers are acceptable input, and the program automatically skips past the hyphen at the appropriate point. /* * This listener was adapted from the "verify input in a template (YYYY/MM/DD)" SWT Code * Snippet (also known as Snippet179), from the Snippets page of the SWT Project. * SWT Code Snippets can be found at: * http://www.eclipse.org/swt/snippets/ */ textBox.addListener(SWT.Verify, new Listener() { boolean ignore; public void handleEvent(Event e) { if (ignore) return; e.doit = false; StringBuffer buffer = new StringBuffer(e.text); char[] chars = new char[buffer.length()]; buffer.getChars(0, chars.length, chars, 0); if (e.character == '\b') { for (int i = e.start; i < e.end; i++) { switch (i) { case 0: /* [x]xxx-xx */ case 1: /* x[x]xx-xx */ case 2: /* xx[x]x-xx */ case 3: /* xxx[x]-xx */ case 5: /* xxxx-[x]x */ case 6: /* xxxx-x[x] */ { buffer.append(' '); break; } case 4: /* xxxx[-]xx */ { buffer.append('-'); break; } default: return; } } textBox.setSelection(e.start, e.start + buffer.length()); ignore = true; textBox.insert(buffer.toString()); ignore = false; textBox.setSelection(e.start, e.start); return; } int start = e.start; if (start > 6) return; int index = 0; for (int i = 0; i < chars.length; i++) { if (start + index == 4) { if (chars[i] == '-') { index++; continue; } buffer.insert(index++, '-'); } if (chars[i] < '0' || '9' < chars[i]) return; index++; } String newText = buffer.toString(); int length = newText.length(); textBox.setSelection(e.start, e.start + length); ignore = true; textBox.insert(newText); ignore = false; /* * After a valid key press, verifying if the input is completed * and passing the cursor to the next text box. */ if (7 == textBox.getCaretPosition()) { /* * Attempting to change the text after receiving a known valid input that has no results (0000-00). */ if ("0000-00".equals(textBox.getText())) { // "0000-00" is the special "Erase Me" code for these text boxes. ignore = true; textBox.setText(" - "); ignore = false; } // Changing focus to a different textBox by using "setFocus()" method. differentTextBox.setFocus(); } } } ); As you can see, the only method I've figured out to clear this text widget from a different point in the code is by assigning "0000-00" textBox.setText("000000") and checking for that input in the listener. When that input is received, the listener changes the text back to " - " (four spaces, a hyphen, then two spaces). There is also a focusLost Listener that parses this text widget for spaces, then in order to avoid unnecessary SQL queries, it clears/resets all fields if the input is invalid (i.e contains spaces). // Adding focus listener to textBox to wait for loss of focus to perform SQL statement. textBox.addFocusListener(new FocusAdapter() { @Override public void focusLost(FocusEvent evt) { // Get the contents of otherTextBox and textBox. (otherTextBox must be <= textBox) String boxFour = otherTextBox.getText(); String boxFive = textBox.getText(); // If either text box has spaces in it, don't perform the search. if (boxFour.contains(" ") || boxFive.contains(" ")) { // Don't perform SQL statements. Debug statement. System.out.println("Tray Position input contains spaces. Ignoring."); //Make all previous results invisible, if any. labels.setVisible(false); differentTextBox.setText(""); labelResults.setVisible(false); } else { //... Perform SQL statement ... } } } ); OK. Often, I use SWT MessageBox widgets in this code to communicate to the user, or wish to change the text widgets back to an empty state after verifying the input. The problem is that messageboxes seem to create a focusLost event, and using the .setText(string) method is subject to SWT.Verify listeners that are present on the text widget. Any suggestions as to selectively ignoring these listeners in code, but keeping them present for all other user input? Thank you in advance for your assistance.

  • ForEach with EditorFor

    - by hermiod
    I have got an Entity model which contains a collection of Message objects which are of the type Message which has several properties, including content, MessageID, from, and to. I have created an EditorTemplate for type Message, however, I cannot get it to display the contents of the Messages collection. There are no errors, but nothing is output. Please note that the view code is from an EditorTemplate for the parent Talkback class. Can you have an EditorTemplate calling another EditorTemplate for a child collection? Both the Talkback and Message class are generated by Entity framework from an existing database. View code: <% foreach (TalkbackEntityTest.Message msg in Model.Messages) { Html.EditorFor(x=> msg, "Message"); } %> This is my template code. It is the standard auto-generated view code with some minor changes. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<TalkbackEntityTest.Message>" %> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.LabelFor(model => model.MessageID) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.MessageID) %> <%: Html.ValidationMessageFor(model => model.MessageID) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.acad_period) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.acad_period) %> <%: Html.ValidationMessageFor(model => model.acad_period) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.talkback_id) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.talkback_id) %> <%: Html.ValidationMessageFor(model => model.talkback_id) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.From) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.From) %> <%: Html.ValidationMessageFor(model => model.From) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.To) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.To) %> <%: Html.ValidationMessageFor(model => model.To) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.SentDatetime) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.SentDatetime, String.Format("{0:g}", Model.SentDatetime)) %> <%: Html.ValidationMessageFor(model => model.SentDatetime) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.content) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.content) %> <%: Html.ValidationMessageFor(model => model.content) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.MessageTypeID) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.MessageTypeID) %> <%: Html.ValidationMessageFor(model => model.MessageTypeID) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> There is definitely content in the Message collection as, if I remove EditorFor and put in response.write on the content property of the Message class, I get the content field for 3 Message objects on the page, which is exactly as expected.

I wanted to create a simple program which will set a pattern for my bigger project but it is taking quite a lot of time than expected. It would be rally helpful if you can explain in simple terms on any template/pattern that i can use to get fluent nHibernate working. The above code uses auto mapping, which i tried after i tried with fluent mapping.

  • Rails: Need a helping hand to finish this Jquery/Ajax problem.

    - by DJTripleThreat
    Here's my problem: I have a combo box that when its index changes I want a div tag with the id="services" to repopulate with checkboxes based on that comboboxes value. I want this to be done using ajax. This is my first time working with ajax for rails so I need a helping hand. Here is what I have so far: My application.js file. Something that Ryan uses in one of his railscasts. This is supposed to be a helper method for handling ajax requests. Is this useful? Should I be using this?: //<![CDATA[ $.ajaxSetup({ 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept","text/javascript")} }); // This function doesn't return any results. How might I change that? Or // should I have another function to do that? $.fn.submitWithAjax = function() { this.submit(function() { $.post($(this).attr("action"), $(this).serialize(), null, "script"); return true; }); }; //]]> An external javascript file for this template (/public/javascripts/combo_box.js): //<![CDATA[ $(document).ready(function(){ $('#event_service_time_allotment').change(function () { // maybe I should be using submitWithAjax(); ?? $(this).parent().submit(); }); }); //]]> My ???.js.erb file. I'm not sure where this file should go. Should I make an ajax controller?? Someone help me out with that part please. I can write this code no problem, I just need to know where it should go and what the file name should be called (best practices etc): // new.js.erb: dynamic choices... expecting a time_allotment alert('test'); // TODO: Return a json object or something with a result set of services // I should be expecting something like: // params[:event_service][:time_allotment] i think which I should use // to return a json object (??) to be parsed or rendered html // for the div#services. Here is my controller's new action. Am I supposed to respond to javascript here? Should I make an ajax controller instead? What's the best way to do this?: # /app/controllers/event_services_controller.rb def new @event_service = EventService.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @event_service } format.js # should I have a javascript handler here? i'm lost! end end My /app/views/event_service/new.html.erb. My ajax call I think should be a different action then the form: <% content_for :head do %> <%= javascript_include_tag '/javascripts/combo_box.js' %> <% end %> <% form_for @event_service, :url => admin_events_path, :html => {:method => :post} do |f| %> <!-- TimeAllotment is a tabless model which is why this is done like so... --> <!-- This select produces an id of: "event_service_time_allotment" and a name of: "event_service[time_allotment]" --> <%= select("event_service", "time_allotment", TimeAllotment.all.collect {|ta| [ta.title, ta.value]}, {:prompt => true}) %> Services: <!-- this div right here needs to be repopulated when the above select changes. --> <div id="services"> <% for service_type in ServiceType.all %> <div> <%= check_box_tag "event_service[service_type_ids][]", service_type.id, false %> <%=h service_type.title %> </div> <% end %> </div> <% end %> ok so right now ALL of the services are there to be chosen from. I want them to change based on what is selected in the combobox event_service_time_allotment. Thanks, I know this is super complicated so any helpful answers will get an upvote.

  • 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.

  • How do I prove I should put a table of values in source code instead of a database table?

    - by FastAl
    <tldr>looking for a reference to a book or other undeniably authoritative source that gives reasons when you should choose a database vs. when you should choose other storage methods. I have provided an un-authoritative list of reasons about 2/3 of the way down this post.</tldr> I have a situation at my company where a database is being used where it would be better to use another solution (in this case, an auto-generated piece of source code that contains a static lookup table, searched by binary sort). Normally, a database would be an OK solution even though the problem does not require a database, e.g, none of the elements of ACID are needed, as it is read-only data, updated about every 3-5 years (also requiring other sourcecode changes), and fits in memory, and can be keyed into via binary search (a tad faster than db, but speed is not an issue). The problem is that this code runs on our enterprise server, but is shared with several PC platforms (some disconnected, some use a central DB, etc.), and parts of it are managed by multiple programming units, parts by the DBAs, parts even by mathematicians in another department, etc. These hit their own platform’s version of their databases (containing their own copy of the static data). What happens is that every implementation, every little change, something different goes wrong. There are many other issues as well. I can’t even use a flatfile, because one mode of running on our enterprise server does not have permission to read files (only databases, and of course, its own literal storage, e.g., in-source table). Of course, other parts of the system use databases in proper, less obscure manners; there is no problem with those parts. So why don’t we just change it? I don’t have administrative ability to force a change. But I’m affected because sometimes I have to help fix the problems, but mostly because it causes outages and tons of extra IT time by other programmers and d*mmit that makes me mad! The reason neither management, nor the designers of the system, can see the problem is that they propose a solution that won’t work: increase communication; implement more safeguards and standards; etc. But every time, in a different part of the already-pared-down but still multi-step processes, a few different diligent, hard-working, top performing IT personnel make a unique subtle error that causes it to fail, sometimes after the last round of testing! And in general these are not single-person failures, but understandable miscommunications. And communication at our company is actually better than most. People just don't think that's the case because they haven't dug into the matter. However, I have it on very good word from somebody with extensive formal study of sociology and psychology that the relatively small amount of less-than-proper database usage in this gigantic cross-platform multi-source, multi-language project is bureaucratically un-maintainable. Impossible. No chance. At least with Human Beings in the loop, and it can’t be automated. In addition, the management and developers who could change this, though intelligent and capable, don’t understand the rigidity of this ‘how humans are’ issue, and are not convincible on the matter. The reason putting the static data in sourcecode will solve the problem is, although the solution is less sexy than a database, it would function with no technical drawbacks; and since the sharing of sourcecode already works very well, you basically erase any database-related effort from this section of the project, along with all the drawbacks of it that are causing problems. OK, that’s the background, for the curious. I won’t be able to convince management that this is an unfixable sociological problem, and that the real solution is coding around these limits of human nature, just as you would code around a bug in a 3rd party component that you can’t change. So what I have to do is exploit the unsuitableness of the database solution, and not do it using logic, but rather authority. I am aware of many reasons, and posts on this site giving reasons for one over the other; I’m not looking for lists of reasons like these (although you can add a comment if I've miss a doozy): WHY USE A DATABASE? instead of flatfile/other DB vs. file: if you need... Random Read / Transparent search optimization Advanced / varied / customizable Searching and sorting capabilities Transaction/rollback Locks, semaphores Concurrency control / Shared users Security 1-many/m-m is easier Easy modification Scalability Load Balancing Random updates / inserts / deletes Advanced query Administrative control of design, etc. SQL / learning curve Debugging / Logging Centralized / Live Backup capabilities Cached queries / dvlp & cache execution plans Interleaved update/read Referential integrity, avoid redundant/missing/corrupt/out-of-sync data Reporting (from on olap or oltp db) / turnkey generation tools [Disadvantages:] Important to get right the first time - professional design - but only b/c it's meant to last s/w & h/w cost Usu. over a network, speed issue (best vs. best design vs. local=even then a separate process req's marshalling/netwk layers/inter-p comm) indicies and query processing can stand in the way of simple processing (vs. flatfile) WHY USE FLATFILE: If you only need... Sequential Row processing only Limited usage append only (no reading, no master key/update) Only Update the record you're reading (fixed length recs only) Too big to fit into memory If Local disk / read-ahead network connection Portability / small system Email / cut & Paste / store as document by novice - simple format Low design learning curve but high cost later WHY USE IN-MEMORY/TABLE (tables, arrays, etc.): if you need... Processing a single db/ff record that was imported Known size of data Static data if hardcoding the table Narrow, unchanging use (e.g., one program or proc) -includes a class that will be shared, but encapsulates its data manipulation Extreme speed needed / high transaction frequency Random access - but search is dependent on implementation Following are some other posts about the topic: http://stackoverflow.com/questions/1499239/database-vs-flat-text-file-what-are-some-technical-reasons-for-choosing-one-over http://stackoverflow.com/questions/332825/are-flat-file-databases-any-good http://stackoverflow.com/questions/2356851/database-vs-flat-files http://stackoverflow.com/questions/514455/databases-vs-plain-text/514530 What I’d like to know is if anybody could recommend a hard, authoritative source containing these reasons. I’m looking for a paper book I can buy, or a reputable website with whitepapers about the issue (e.g., Microsoft, IBM), not counting the user-generated content on those sites. This will have a greater change to elicit a change that I’m looking for: less wasted programmer time, and more reliable programs. Thanks very much for your help. You win a prize for reading such a large post!

  • Repopulating a collection of Backbone forms with previously submitted data

    - by Brian Wheat
    I am able to post my forms to my database and I have stepped through my back end function to check and see that my Get function is returning the same data I submitted. However I am having trouble understanding how to have this data rendered upon visiting the page again. What am I missing? The intention is to be able to create, read, update, or delete (CRUD) some personal contact data for a variable collection of individuals. //Model var PersonItem = Backbone.Model.extend({ url: "/Application/PersonList", idAttribute: "PersonId", schema: { Title: { type: 'Select', options: function (callback) { $.getJSON("/Application/GetTitles/").done(callback); } }, Salutation: { type: 'Select', options: ['Mr.', 'Mrs.', 'Ms.', 'Dr.'] }, FirstName: 'Text', LastName: 'Text', MiddleName: 'Text', NameSuffix: 'Text', StreetAddress: 'Text', City: 'Text', State: { type: 'Select', options: function (callback) { $.getJSON("/Application/GetStates/").done(callback); } }, ZipCode: 'Text', PhoneNumber: 'Text', DateOfBirth: 'Date', } }); Backbone.Form.setTemplates(template, PersonItem); //Collection var PersonList = Backbone.Collection.extend({ model: PersonItem , url: "/Application/PersonList" }); //Views var PersonItemView = Backbone.Form.extend({ tagName: "li", events: { 'click button.delete': 'remove', 'change input': 'change' }, initialize: function (options) { console.log("ItemView init"); PersonItemView.__super__.initialize.call(this, options); _.bindAll(this, 'render', 'remove'); console.log("ItemView set attr = " + options); }, render: function () { PersonItemView.__super__.render.call(this); $('fieldset', this.el).append("<button class=\"delete\" style=\"float: right;\">Delete</button>"); return this; }, change: function (event) { var target = event.target; console.log('changing ' + target.id + ' from: ' + target.defaultValue + ' to: ' + target.value); }, remove: function () { console.log("delete button pressed"); this.model.destroy({ success: function () { alert('person deleted successfully'); } }); return false; } }); var PersonListView = Backbone.View.extend({ el: $("#application_fieldset"), events: { 'click button#add': 'addPerson', 'click button#save': 'save2db' }, initialize: function () { console.log("PersonListView Constructor"); _.bindAll(this, 'render', 'addPerson', 'appendItem', 'save'); this.collection = new PersonList(); this.collection.bind('add', this.appendItem); //this.collection.fetch(); this.collection.add([new PersonItem()]); console.log("collection length = " + this.collection.length); }, render: function () { var self = this; console.log(this.collection.models); $(this.el).append("<button id='add'>Add Person</button>"); $(this.el).append("<button id='save'>Save</button>"); $(this.el).append("<fieldset><legend>Contact</legend><ul id=\"anchor_list\"></ul>"); _(this.collection.models).each(function (item) { self.appendItem(item); }, this); $(this.el).append("</fieldset>"); }, addPerson: function () { console.log("addPerson clicked"); var item = new PersonItem(); this.collection.add(item); }, appendItem: function (item) { var itemView = new PersonItemView({ model: item }); $('#anchor_list', this.el).append(itemView.render().el); }, save2db: function () { var self = this; console.log("PersonListView save"); _(this.collection.models).each(function (item) { console.log("item = " + item.toJSON()); var cid = item.cid; console.log("item.set"); item.set({ Title: $('#' + cid + '_Title').val(), Salutation: $('#' + cid + '_Salutation').val(), FirstName: $('#' + cid + '_FirstName').val(), LastName: $('#' + cid + '_LastName').val(), MiddleName: $('#' + cid + '_MiddleName').val(), NameSuffix: $('#' + cid + '_NameSuffix').val(), StreetAddress: $('#' + cid + '_StreetAddress').val(), City: $('#' + cid + '_City').val(), State: $('#' + cid + '_State').val(), ZipCode: $('#' + cid + '_ZipCode').val(), PhoneNumber: $('#' + cid + '_PhoneNumber').val(), DateOfBirth: $('#' + cid + '_DateOfBirth').find('input').val() }); if (item.isNew()) { console.log("item.isNew"); self.collection.create(item); } else { console.log("!item.isNew"); item.save(); } }); return false; } }); var personList = new PersonList(); var view = new PersonListView({ collection: personList }); personList.fetch({ success: function () { $("#application_fieldset").append(view.render()); } });

  • Embedding mercurial revision information in Visual Studio c# projects automatically

    - by Mark Booth
    Original Problem In building our projects, I want the mercurial id of each repository to be embedded within the product(s) of that repository (the library, application or test application). I find it makes it so much easier to debug an application ebing run by custiomers 8 timezones away if you know precisely what went into building the particular version of the application they are using. As such, every project (application or library) in our systems implement a way of getting at the associated revision information. I also find it very useful to be able to see if an application has been compiled with clean (un-modified) changesets from the repository. 'Hg id' usefully appends a + to the changeset id when there are uncommitted changes in a repository, so this allows is to easily see if people are running a clean or a modified version of the code. My current solution is detailed below, and fulfills the basic requirements, but there are a number of problems with it. Current Solution At the moment, to each and every Visual Studio solution, I add the following "Pre-build event command line" commands: cd $(ProjectDir) HgID I also add an HgID.bat file to the Project directory: @echo off type HgId.pre > HgId.cs For /F "delims=" %%a in ('hg id') Do <nul >>HgID.cs set /p = @"%%a" echo ; >> HgId.cs echo } >> HgId.cs echo } >> HgId.cs along with an HgId.pre file, which is defined as: namespace My.Namespace { /// <summary> Auto generated Mercurial ID class. </summary> internal class HgID { /// <summary> Mercurial version ID [+ is modified] [Named branch]</summary> public const string Version = When I build my application, the pre-build event is triggered on all libraries, creating a new HgId.cs file (which is not kept under revision control) and causing the library to be re-compiled with with the new 'hg id' string in 'Version'. Problems with the current solution The main problem is that since the HgId.cs is re-created at each pre-build, every time we need to compile anything, all projects in the current solution are re-compiled. Since we want to be able to easily debug into our libraries, we usually keep many libraries referenced in our main application solution. This can result in build times which are significantly longer than I would like. Ideally I would like the libraries to compile only if the contents of the HgId.cs file has actually changed, as opposed to having been re-created with exactly the same contents. The second problem with this method is it's dependence on specific behaviour of the windows shell. I've already had to modify the batch file several times, since the original worked under XP but not Vista, the next version worked under Vista but not XP and finally I managed to make it work with both. Whether it will work with Windows 7 however is anyones guess and as time goes on, I see it more likely that contractors will expect to be able to build our apps on their Windows 7 boxen. Finally, I have an aesthetic problem with this solution, batch files and bodged together template files feel like the wrong way to do this. My actual questions How would you solve/how are you solving the problem I'm trying to solve? What better options are out there than what I'm currently doing? Rejected Solutions to these problems Before I implemented the current solution, I looked at Mercurials Keyword extension, since it seemed like the obvious solution. However the more I looked at it and read peoples opinions, the more that I came to the conclusion that it wasn't the right thing to do. I also remember the problems that keyword substitution has caused me in projects at previous companies (just the thought of ever having to use Source Safe again fills me with a feeling of dread *8'). Also, I don't particularly want to have to enable Mercurial extensions to get the build to complete. I want the solution to be self contained, so that it isn't easy for the application to be accidentally compiled without the embedded version information just because an extension isn't enabled or the right helper software hasn't been installed. I also thought of writing this in a better scripting language, one where I would only write HgId.cs file if the content had actually changed, but all of the options I could think of would require my co-workers, contractors and possibly customers to have to install software they might not otherwise want (for example cygwin). Any other options people can think of would be appreciated. Update Partial solution Having played around with it for a while, I've managed to get the HgId.bat file to only overwrite the HgId.cs file if it changes: @echo off type HgId.pre > HgId.cst For /F "delims=" %%a in ('hg id') Do <nul >>HgId.cst set /p = @"%%a" echo ; >> HgId.cst echo } >> HgId.cst echo } >> HgId.cst fc HgId.cs HgId.cst >NUL if %errorlevel%==0 goto :ok copy HgId.cst HgId.cs :ok del HgId.cst Problems with this solution Even though HgId.cs is no longer being re-created every time, Visual Studio still insists on compiling everything every time. I've tried looking for solutions and tried checking "Only build startup projects and dependencies on Run" in Tools|Options|Projects and Solutions|Build and Run but it makes no difference. The second problem also remains, and now I have no way to test if it will work with Vista, since that contractor is no longer with us. If anyone can test this batch file on a Windows 7 and/or Vista box, I would appreciate hearing how it went. Finally, my aesthetic problem with this solution, is even strnger than it was before, since the batch file is more complex and this there is now more to go wrong. If you can think of any better solution, I would love to hear about them.

  • asp .net MVC 2.0 Validation

    - by ANDyW
    Hi I’m trying to do some validation in asp .net MVC 2.0 for my application. I want to have some nice client side validation. Validation should be done most time on model side with DataAnnotations with custom attributes( like CompareTo, StringLenght, MinPasswordLenght (from Membership.MinimumumpassworkdLenght value). For that purpose I tried to use xval with jquery.validation. Some specific thing is that most of forms will be working with ajax and most problems are when I want to validate form with ajax. Here is link for sample project http://www.sendspace.com/file/m9gl54 . I got two forms as controls ValidFormControl1.ascx, ValidFormControl2.ascx <% using (Ajax.BeginForm("CreateValidForm", "Test", new AjaxOptions { HttpMethod = "Post" })) {%> <div id="validationSummary1"> <%= Html.ValidationSummary(true)%> </div> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Name)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Name)%> <%= Html.ValidationMessageFor(model => model.Name)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Email)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Email)%> <%= Html.ValidationMessageFor(model => model.Email)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Password)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Password)%> <%= Html.ValidationMessageFor(model => model.Password)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.ConfirmPassword)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ConfirmPassword)%> <%= Html.ValidationMessageFor(model => model.ConfirmPassword)%> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> <%= Html.ClientSideValidation<ValidModel>() .UseValidationSummary("validationSummary1", "Please fix the following problems:") %> Both look same the difference is only validation summaryID (validationSummary1, validationSummary2). Both controls are rendered on one page : Form2 <%Html.RenderPartial("~/Views/Test/ValidFormControl2.ascx", null); %> Form1 <%Html.RenderPartial("~/Views/Test/ValidFormControl.ascx", null); %> Validation property First problem, when we have two controls with same type to validate it don’t work becosue html elements are rendered by field name ( so we have two element with same name “Password” ). Only first form will be validated by client side. The worst thing is that even if we have different types and their fields name is same validation won’t work too ( this thing is what I need to repair it will be stupid to name some unique properites for validation ). Is there any solution for this ? Custom attributes validation Next thing custom attributes validation ( All those error are when I use Ajax for on normal form validation is working without problem. ): CompareTo - Simple compare to that is done in mvc template for account model ( class attribute saying with two property will be compared ) , and it wasn’t show on page. To do it I created own CachingRulesProvider with compareRule and my Attribute. Maybe there is more easy way to do it? StringLenght with minimum and maximum value, I won’t describe how I done it but is there any easy whey to do it? Validation summary When I have two two control on page all summary validation information goes to first control validation summary element, even xval generated script say that elementID are different for summary. Any one know how to repair it? Validation Information Is there any option to turn on messages on place where is Html.ValidationMessageFor(model = model.ConfirmPassword). Becsoue for me it isn’t show up. I would like to have summary and near field information too not only red border. Any one know how to do it? Ajax submit Anyone know how to do easy without massive code in javascript to do submit via javascript. This will be used to change input submit to href element (a). Both look same the difference is only validation summaryID
