  • C#: Determine Type for (De-)Serialization

    - by dbemerlin
    Hi, i have a little problem implementing some serialization/deserialization logic. I have several classes that each take a different type of Request object, all implementing a common interface and inheriting from a default implementation: This is how i think it should be: Requests interface IRequest { public String Action {get;set;} } class DefaultRequest : IRequest { public String Action {get;set;} } class LoginRequest : DefaultRequest { public String User {get;set;} public String Pass {get;set;} } Handlers interface IHandler<T> { public Type GetRequestType(); public IResponse HandleRequest(IModel model, T request); } class DefaultHandler<T> : IHandler<T> // Used as fallback if the handler cannot be determined { public Type GetRequestType() { return /* ....... how to get the Type of T? ((new T()).GetType()) ? .......... */ } public IResponse HandleRequest(IModel model, T request) { /* ... */ } } class LoginHandler : DefaultHandler<LoginRequest> { public IResponse HandleRequest(IModel mode, LoginRequest request) { } } Calling class Controller { public ProcessRequest(String action, String serializedRequest) { IHandler handler = GetHandlerForAction(action); IRequest request = serializer.Deserialize<handler.GetRequestType()>(serializedRequest); handler(this.Model, request); } } Is what i think of even possible? My current Solution is that each handler gets the serialized String and is itself responsible for deserialization. This is not a good solution as it contains duplicate code, the beginning of each HandleRequest method looks the same (FooRequest request = Deserialize(serializedRequest); + try/catch and other Error Handling on failed deserialization). Embedding type information into the serialized Data is not possible and not intended. Thanks for any Hints.

  • Obtain container type from (its) iterator type in C++ (STL)

    - by KRao
    It is easy given a container to get the associated iterators, example: std::vector<double>::iterator i; //An iterator to a std::vector<double> I was wondering if it is possible, given an iterator type, to deduce the type of the "corresponding container" (here I am assuming that for each container there is one and only one (non-const) iterator). More precisely, I would like a template metafunction that works with all STL containers (without having to specialize it manually for each single container) such that, for example: ContainerOf< std::vector<double>::iterator >::type evaluates to std::vector<double> Is it possible? If not, why? Thank you in advance for any help!

  • ASP.NET Creating a Rich Repeater, DataBind wiping out custom added controls...

    - by tonyellard
    So...I had this clever idea that I'd create my own Repeater control that implements paging and sorting by inheriting from Repeater and extending it's capabilities. I found some information and bits and pieces on how to go about this and everything seemed ok... I created a WebControlLibrary to house my custom controls. Along with the enriched repeater, I created a composite control that would act as the "pager bar", having forward, back and page selection. My pager bar works 100% on it's own, properly firing a paged changed event when the user interacts with it. The rich repeater databinds without issue, but when the databind fires (when I call base.databind()), the control collection is cleared out and my pager bars are removed. This screws up the viewstate for the pager bars making them unable to fire their events properly or maintain their state. I've tried adding the controls back to the collection after base.databind() fires, but that doesn't solve the issue. I start to get very strange results including problems with altering the hierarchy of the control tree (resolved by adding [ViewStateModeById]). Before I go back to the drawing board and create a second composite control which contains a repeater and the pager bars (so that the repeater isn't responsible for the pager bars viewstate) are there any thoughts about how to resolve the issue? In the interest of share and share alike, the code for the repeater itself is below, the pagerbars aren't as significant as the issue is really the maintaining of state for any additional child controls. (forgive the roughness of some of the code...it's still a work in progress) using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; using System.Data; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; [ViewStateModeById] public class SortablePagedRepeater : Repeater, INamingContainer { private SuperRepeaterPagerBar topBar = new SuperRepeaterPagerBar(); private SuperRepeaterPagerBar btmBar = new SuperRepeaterPagerBar(); protected override void OnInit(EventArgs e) { Page.RegisterRequiresControlState(this); InitializeControls(); base.OnInit(e); EnsureChildControls(); } protected void InitializeControls() { topBar.ID = this.ID + "__topPagerBar"; topBar.NumberOfPages = this._currentProperties.numOfPages; topBar.CurrentPage = this.CurrentPageNumber; topBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); btmBar.ID = this.ID + "__btmPagerBar"; btmBar.NumberOfPages = this._currentProperties.numOfPages; btmBar.CurrentPage = this.CurrentPageNumber; btmBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); } protected override void CreateChildControls() { EnsureDataBound(); this.Controls.Add(topBar); this.Controls.Add(btmBar); //base.CreateChildControls(); } private void PageChanged(object sender, int newPage) { this.CurrentPageNumber = newPage; } public override void DataBind() { //pageDataSource(); //DataBind removes all controls from control collection... base.DataBind(); Controls.Add(topBar); Controls.Add(btmBar); } private void pageDataSource() { //Create paged data source PagedDataSource pds = new PagedDataSource(); pds.PageSize = this.ItemsPerPage; pds.AllowPaging = true; // first get a PagedDataSource going and perform sort if possible... if (base.DataSource is System.Collections.IEnumerable) { pds.DataSource = (System.Collections.IEnumerable)base.DataSource; } else if (base.DataSource is System.Data.DataView) { DataView data = (DataView)DataSource; if (this.SortBy != null && data.Table.Columns.Contains(this.SortBy)) { data.Sort = this.SortBy; } pds.DataSource = data.Table.Rows; } else if (base.DataSource is System.Data.DataTable) { DataTable data = (DataTable)DataSource; if (this.SortBy != null && data.Columns.Contains(this.SortBy)) { data.DefaultView.Sort = this.SortBy; } pds.DataSource = data.DefaultView; } else if (base.DataSource is System.Data.DataSet) { DataSet data = (DataSet)DataSource; if (base.DataMember != null && data.Tables.Contains(base.DataMember)) { if (this.SortBy != null && data.Tables[base.DataMember].Columns.Contains(this.SortBy)) { data.Tables[base.DataMember].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[base.DataMember].DefaultView; } else if (data.Tables.Count > 0) { if (this.SortBy != null && data.Tables[0].Columns.Contains(this.SortBy)) { data.Tables[0].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[0].DefaultView; } else { throw new Exception("DataSet doesn't have any tables."); } } else if (base.DataSource == null) { // don't do anything? } else { throw new Exception("DataSource must be of type System.Collections.IEnumerable.

    I have been using Ubuntu for few weeks now and I am have been trying to create custom menu which to add in the launcher. Please, note that my version is 12.04 and I have not got any experience with Linux. I have checked a lot articles and questions likes this one, but have not been able to find what I am looking for. I want to create a custom quick launcher menu and to add it the the standard launcher, but I want to add links to other programs or folders in it. For example: A browsers menu - when it is open (with right mouse click on it), my browsers will be listed: chrome safari opera firefox I even may add their icons there. Music menu - some shortcuts to my favorite music folders.

  • Workflow Foundation (WF) -- Why does Visual Studio's designer not use my custom ActivityDesignerThem

    - by stakx
    Problem: I am trying to customize a custom Workflow Foundation activity (called CustomActivity) so that it will display with a specific background color. What I've got so far: First, I'm defining a custom ActivityDesignerTheme as follows: public class CustomActivityTheme : ActivityDesignerTheme { public CustomActivityTheme(WorkflowTheme theme) : base(theme) { this.BackColorStart = Color.FromArgb(0xff, 0xf4, 0xf4, 0xf4); this.BackColorEnd = Color.FromArgb(0xff, 0xc0, 0xc0, 0xc0); this.BackgroundStyle = LinearGradientMode.Horizontal; } } Then, I am applying this theme to a custom ActivityDesigner (apparently the theme must be applied to a designer, and not to an activity): [ActivityDesignerTheme(typeof(CustomActivityTheme))] public class CustomActivityDesigner : SequentialActivityDesigner { ... } Ultimately, I am applying the custom designer to my custom Activity: [Designer(typeof(CustomActivityDesigner))] public partial class CustomActivity : SequenceActivity { ... } Now, according to some code examples that I've seen, this should do the trick. However, when I include an instance of my CustomActivity in a workflow, my custom theme is not applied and it is displayed in the Visual Studio Designer as any standard activity would (white background etc.). I tried re-compiling and even re-starting Visual Studio a couple of times, just to make sure the used assembly is up-to-date, but to no avail. My question: What am I missing? Why does Visual Studio's Workflow Designer not respect the CustomActivityTheme when it displays a CustomActivity?

  • Magento - Show Custom Attributes in Grouped Product table.

    - by greencoconut
    I need to find a way to show the value of a custom attribute in place of the "Product Name" shown in the image below. I'm working with /app/design/frontend/default/defaultx/template/catalog/product/view/type/grouped.php The code below doesn't work(the custom attribute is yearmade): <?php if (count($_associatedProducts)): ?> <?php foreach ($_associatedProducts as $_item): ?> <tr> <td><?php echo $this->htmlEscape($_item->getYearmade()) ?></td> Any help would be appreciated. EDIT: So the answer turned out to be quite simple. You see what I failed to mention above was that there was indeed output... but that it was just a number (eg: 52). Turns out this was the ID for that custom attribute value (It was a Dropdown type of custom attribute). So in summary This works for custom attributes of type text: echo $this->htmlEscape($_item->getYearmade()) But for all other types of custom attribute (I think), the following should be used: echo $this->htmlEscape($_item->getAttributeText('yearmade')) I would not have discovered this without the most excellent answer provided by Alan Storm, below. Thank you sir.

  • Object of type "X" cannot be converted to object of type "X"

    - by Benjol
    (Can't believe this hasn't already been asked, but I can't find a dup) In Visual Studio with lots of projects, when I first open the solution, I sometimes get the warning Object of type "X" cannot be converted to object of type "X". Generally rebuilding seems to make it go away, but does anyone know what this is caused by, and how to avoid it? UPDATE I read somewhere that deleting all your resx files and rebuilding can help. I unthinkingly tried this. Not a good idea...

  • How to find out if an object is of <type> or a decendant of <type>

    - by Vaccano
    I have the following code: foreach (var control in this.Controls) { } I want to do something like control.Hide() in there. But the items in the this.Controls collection are not of type Control (they are Object). I can't seem to remember the safe way to cast this to call hide if it is really of type Control and do nothing otherwise. (I am a transplanted delphi programmer and I keep thinking something like control is Control.)

  • changing restriction on simple type in extended complex type

    - by rotary_engine
    I am trying to create a schema that has 2 address types. The first AdressType requires an element Line 1 to have a value at least 10 characters. The second type OtherAdressType derives from this with the same elements, but does not require a value for Line 1. I've tried different ways but always get schema errors, this error is: Invalid particle derivation by restriction - 'Derived element '{namespace}:Line1' is not a valid restriction of base element '{namespace}:Line1' according to Elt:Elt -- NameAndTypeOK.'. If I add a type xs:string to OtherAdressType:Line1 then I get other errors. <xs:complexType name="AdressType"> <xs:sequence> <xs:element name="Line1" minOccurs="1" maxOccurs="1"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="10" /> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="Line2" type="xs:string" minOccurs="1" maxOccurs="1" /> </xs:sequence> </xs:complexType> <xs:complexType name="OtherAdressType"> <xs:complexContent> <xs:restriction base="AdressType"> <xs:sequence> <xs:element name="Line1" nillable="true"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="0" /> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="Line2" type="xs:string" minOccurs="1" maxOccurs="1" /> </xs:sequence> </xs:restriction> </xs:complexContent> </xs:complexType>

  • [NSIS] Custom radio-buttom INI page via Eclipse

    - by Omegazero
    I'm using Eclipse's create InstallOptions menu to create a custom INI page with radio-buttons for repackaging the Blackberry Desktop installer. There are 2 sections for each type: "Internet" and "Enterprise". I need a user to select 1 of the 2 options and depending on their selection, the page will carry over the selection chosen in the custom page, jump to the INSTFILES page, and continue onto the end. I couldn't find any concrete documentation on getting INI pages to load in the script (I'm probably searching incorrectly), and then pass data from one page to the next (according to fields I guess?)

  • Idiomatic Scala way to deal with base vs derived class field names?

    - by Gregor Scheidt
    Consider the following base and derived classes in Scala: abstract class Base( val x : String ) final class Derived( x : String ) extends Base( "Base's " + x ) { override def toString = x } Here, the identifier 'x' of the Derived class parameter overrides the field of the Base class, so invoking toString like this: println( new Derived( "string" ).toString ) returns the Derived value and gives the result "string". So a reference to the 'x' parameter prompts the compiler to automatically generate a field on Derived, which is served up in the call to toString. This is very convenient usually, but leads to a replication of the field (I'm now storing the field on both Base and Derived), which may be undesirable. To avoid this replication, I can rename the Derived class parameter from 'x' to something else, like '_x': abstract class Base( val x : String ) final class Derived( _x : String ) extends Base( "Base's " + _x ) { override def toString = x } Now a call to toString returns "Base's string", which is what I want. Unfortunately, the code now looks somewhat ugly, and using named parameters to initialize the class also becomes less elegant: new Derived( _x = "string" ) There is also a risk of forgetting to give the derived classes' initialization parameters different names and inadvertently referring to the wrong field (undesirable since the Base class might actually hold a different value). Is there a better way? Edit: To clarify, I really only want the Base values; the Derived ones just seem necessary for initializing the Base ones. The example only references them to illustrate the ensuing issues. It might be nice to have a way to suppress automatic field generation if the derived class would otherwise end up hiding a base class field.

  • Display a input type=file over another input type=file

    - by Kevin Sedgley
    WARNING: Lengthy description coming up! I have written an uploader based upon APC progress uploader for PHP. This works fine and dandy, but the script as a whole (apc etc) is intended to be used only for those with Javascript. To achieve this, I have searched for any input type=file, and replaced these with an absolutely positioned form that appears over the original area where the old file input area was. The reasons for this are so the new uploader can submit to a hidden in page IFrame has to be in a seperate <form> in order to submit to the APC reciever to display the progress upload bar. allows it to be used within any form with an input type=file throughout the site I have used JQuery to do this, with the following code: Original HTML form code: <div><input type="file" name="media" id="media" /></div> Find position of div block code: // get the parent div, and properties thereof parentDiv = $(this).closest('div'); w = $(parentDiv).width(); h = $(parentDiv).height(); loc = $(parentDiv).offset(); Locate new block over old block: $('#_sender').appendTo('body').css({left:loc.left,top:loc.top,position:'absolute',zIndex:400,height:h,width:w}).show(); This works fine, and shows over the old block OK. The problem: When other elements in the DOM before or above it change (in this case a "tree view" selector is pushing the old block down) the new upload form gets moved over other elements. Is there a JQuery (or JS) method for changing this upon DOM change? Some kind of .onchange for the page?! Or an .onmove for the original block? Thanks in advance you lovely people Before DOM change: . After: .

  • Bind postback data from a strong type view of type List<T>

    - by Robert Koritnik
    I have a strong type view of type List<List<MyViewModelClass>> The outer list will always have two lists of List<MyViewModelClass>. For each of the two outer lists I want to display a group of checkboxes. Each set can have an arbitrary number of choices. My view model class looks similar to this: public class MyViewModelClass { public Area Area { get; set; } public bool IsGeneric { get; set; } public string Code { get; set; } public bool IsChecked { get; set; } } So the final view will look something like: Please select those that apply: First set of choices: x Option 1 x Option 2 x Option 3 etc. Second set of choices: x Second Option 1 x Second Option 2 x Second Option 3 x Second Option 4 etc. Checkboxes should display MyViewModelClass.Area.Name, and their value should be related to MyViewModelClass.Area.Id. Checked state is of course related to MyViewModel.IsChecked. Question I wonder how should I use Html.CheckBox() or Html.CheckBoxFor() helper to display my checkboxes? I have to get these values back to the server on a postback of course. I would like to have my controller action like one of these: public ActionResult ConsumeSelections(List<List<MyViewModelClass>> data) { // process data } public ActionResult ConsumeSelections(List<MyViewModelClass> first, List<MyViewModelClass> second) { // process data } If it makes things simpler, I could make a separate view model type like: public class Options { public List First { get; set; } public List Second { get; set; } } As well as changing my first version of controller action to: public ActionResult ConsumeSelections(Options data) { // process data }

  • PHP preg_match: a pattern which satisfies all MySQL field names (including 'table.field' formations)

    - by gsquare567
    i need a pattern which satisfies mysql field names, but also with the option of having a table name before it examples: mytable.myfield myfield my4732894__7289FiEld here's what i tried: $pattern = "/^[a-zA-Z0-9_]*?[\.[a-zA-Z0-9_]]?$/"; this worked for what i needed before, which was just the field name: $pattern = "/^[a-zA-Z0-9_]*$/"; any ideas why my addition isnt working? maybe i'm making up regex, so i'll explain what i added... the first '?' is to say that it isn't greedy, ie. it will stop if the next part, namely "[.[a-zA-Z0-9_]]?" is satisfied. now, that second part is just the same as the first except it is optional (hence the '?' at the end) and it starts with a period (hence the '[.' and ']' wrapping my old clause. and obviously, the "^" and "$" rep the beginning and end of the string so... any ideas? (also, i'm a tad confused as to why i need to put in those "/"s in the begining/end anyways, so if you could tell me why it's required, that'd be awesome) thanks a lot! (and thanks for reading this all if you actually did... it's quite a ramble)
