  • MSForms.ListBox Type Mismatch in Access

    - by Jason
    I have an Access database where I use a Tab control (without tabs) to simulate a wizard. One of the tab pages has an MSForms.ListBox control called lstPorts, and a button named cmdAdd which adds the contents of a textbox to the List Box. I then try to keep the contents of the ListBox sorted. However, the call to the Sort method causes a type mismatch. Here is the cmdAdd_Click() code behind: Private Sub cmdAdd_Click() Dim test As MSForms.ListBox lstPorts2.AddItem (txtPortName) Call SortListBox(lstPorts2) End Sub Here is the SortListBox Sub: Public Sub SortListBox(ByRef oLb As MSForms.ListBox) Dim vaItems As Variant Dim i As Long, j As Long Dim vTemp As Variant 'Put the items in a variant array vaItems = oLb.List For i = LBound(vaItems, 1) To UBound(vaItems, 1) - 1 For j = i + 1 To UBound(vaItems, 1) If vaItems(i, 0) > vaItems(j, 0) Then vTemp = vaItems(i, 0) vaItems(i, 0) = vaItems(j, 0) vaItems(j, 0) = vTemp End If Next j Next i 'Clear the listbox oLb.Clear 'Add the sorted array back to the listbox For i = LBound(vaItems, 1) To UBound(vaItems, 1) oLb.AddItem vaItems(i, 0) Next i End Sub Any help out there? Since the Sort routine explicitly references the MSForms.ListBox, most of the results from Google aren't applicable. Jason

  • @PersistenceContext cannot be resolved to a type

    i was running a code in which there's a dependency @PersistenceContext and field private EntityManager em; both of which cannot be resolved to a type, what is the meaning of this error and how can i fix it? the code is here: package org.jboss.tools.examples.util; import java.util.logging.Logger;` import javax.enterprise.context.RequestScoped; import javax.enterprise.inject.Produces; import javax.enterprise.inject.spi.InjectionPoint; import javax.faces.context.FacesContext; /** * This class uses CDI to alias Java EE resources, such as the persistence context, to CDI beans * * <p> * Example injection on a managed bean field: * </p> * * <pre> * &#064;Inject * private EntityManager em; * </pre> */ public class Resources { // use @SuppressWarnings to tell IDE to ignore warnings about field not being referenced directly @SuppressWarnings("unused") @Produces @PersistenceContext private EntityManager em; @Produces public Logger produceLog(InjectionPoint injectionPoint) { return Logger.getLogger(injectionPoint.getMember().getDeclaringClass().getName()); } @Produces @RequestScoped public FacesContext produceFacesContext() { return FacesContext.getCurrentInstance(); } }

  • Illegal offset type error when => value is omitted

    - by thomas
    Line 3 of the code below fails if I omit the => $v portion. I get the following error: Warning: Illegal offset type in /home/site/page.php on line 404 When the [$k] in line 5 is changed to ['$k'], i receive the following error. Notice: Undefined index: $k in /home/site/page.php on line 404 When it is like below with the the full $k => $v everything works though. I don't even use $v. Why do I need it in the foreach loop to make it work then? <? if ( $arr[ 'status'][ 'chain'] ) { foreach ( $arr[ 'status'][ 'chain'] as $k => $v) { ?> <tr> <td class="line_item_data status_td"> <?= $ arr[ 'status'][ 'chain'][$k][ 'message'] ?> </td> <td align="center"> <img src="images/green_check.gif" width="20" /> </td> </tr> <? } } ?> I did see this answer, but don't know that it really applies. Thanks so much!

  • How to load a type in parent-child website

    - by salvationishere
    I am developing a C# VS 2008 / SQL Server 2008 website. Although this same code compiles in the Project version, the website version does not compile. Many of their files are the same so I do not understand even where to look. The only compile error I get is: Could not load type 'DataMatch' in my DataMatch.aspx file. Is the problem in my web.config file? How do websites differ from projects in VS? All four of these files reside in same directory.

  • Cannot inherit from generic base class and specific interface using same type with generic constrain

    - by simendsjo
    Sorry about the strange title. I really have no idea how to express it any better... I get an error on the following snippet. I use the class Dummy everywhere. Doesn't the compiler understand the constraint I've added on DummyImplBase? Is this a compiler bug as it works if I use Dummy directly instead of setting it as a constraint? Error 1 'ConsoleApplication53.DummyImplBase' does not implement interface member 'ConsoleApplication53.IRequired.RequiredMethod()'. 'ConsoleApplication53.RequiredBase.RequiredMethod()' cannot implement 'ConsoleApplication53.IRequired.RequiredMethod()' because it does not have the matching return type of 'ConsoleApplication53.Dummy'. C:\Documents and Settings\simen\My Documents\Visual Studio 2008\Projects\ConsoleApplication53\ConsoleApplication53\Program.cs 37 27 ConsoleApplication53 public class Dummy { } public interface IRequired<T> { T RequiredMethod(); } public interface IDummyRequired : IRequired<Dummy> { void OtherMethod(); } public class RequiredBase<T> : IRequired<T> { public T RequiredMethod() { return default(T); } } public abstract class DummyImplBase<T> : RequiredBase<T>, IDummyRequired where T: Dummy { public void OtherMethod() { } }

  • How can I restore the "auto" values with for list-style-type in nested unordered lists with CSS?

    - by Michael
    By default, an unstyled set of nested <ul> lists looks like this (in Chrome, Firefox, and IE at least): The top level has a list-style-type of disc, the next level is circle, and subsequent levels are square. If I include a stylesheet that changes the list-style-type to none, is there a simple way to revert back to the "automatic bullet types" later in the document? (e.g., override with a subsequent CSS definition or JavaScript style change) Basically, I'm looking for something like list-style-type: auto; (which is apparently not valid and has no effect): <style type="text/css"> ul { list-style-type: none; } ul { list-style-type: auto; } /* Does not work */ </style> Setting the list-style-type back to disc changes every bullet in the list and I no longer see different bullets at different levels, so that doesn't work either. Is the only way to accomplish this by explicitly defining styles for every level? e.g.: <style type="text/css"> ul { list-style-type: disc; } ul ul { list-style-type: circle; } ul ul ul { list-style-type: square; } </style>

  • How to collect and inject all beans of a given type in Spring XML configuration

    - by GrzegorzOledzki
    One of the strongest accents of the Spring framework is the Dependency Injection concept. I understand one of the advices behind that is to separate general high-level mechanism from low-level details (as announced by Dependency Inversion Principle). Technically, that boils down to having a bean implementation to know as little as possible about a bean being injected as a dependency, e.g. public class PrintOutBean { private LogicBean logicBean; public void action() { System.out.println(logicBean.humanReadableDetails()); } //... } <bean class="PrintOutBean"> <property name="loginBean" ref="ShoppingCartBean"/> </bean> But what if I wanted to a have a high-level mechanism operating on multiple dependent beans? public class MenuManagementBean { private Collection<Option> options; public void printOut() { for (Option option:options) { // do something for option } //... } } I know one solution would be to use @Autowired annotation in the singleton bean, that is... @Autowired private Collection<Option> options; But doesn't it violate the separation principle? Why do I have to specify what dependents to take in the very same place I use them (i.e. MenuManagementBean class in my example)? Is there a way to inject collections of beans in the XML configuration like this (without any annotation in the MMB class)? <bean class="MenuManagementBean"> <property name="options"> <xxx:autowire by-type="MyOptionImpl"/> </property> </bean>

  • SQLAlchemy Custom Type Which Contains Multiple Columns

    - by Kekoa
    I would like to represent a datatype as a single column in my model, but really the data will be stored in multiple columns in the database. I cannot find any good resources on how to do this in SQLAlchemy. I would like my model to look like this(this is a simplified example using geometry instead of my real problem which is harder to explain): class 3DLine(DeclarativeBase): start_point = Column(my.custom.3DPoint) end_point = Column(my.custom.3DPoint) This way I could assign an object with the (x, y, z) components of the point at once without setting them individually. If I had to separate each component, this could get ugly, especially if each class has several of these composite objects. I would combine the values into one encoded field except that I need to query each value separately at times. I was able to find out how to make custom types using a single column in the documentation. But there's no indication that I can map a single type to multiple columns. I suppose I could accomplish this by using a separate table, and each column would be a foreign key, but in my case I don't think it makes sense to have a one to one mapping for each point to a separate table, and this still does not give the ability to set the related values all at once.

  • Type of member is not CLS-compliant

    - by John Galt
    Using Visual Studio 2008 and VB.Net: I have a working web app that uses an ASMX web service which is compiled into its separate assembly. I have another class library project compiled as a separate assembly that serves as a proxy to this web service. This all seems to work at runtime but I am getting this warning at compile time which I don't understand and would like to fix: Type of member 'wsZipeee' is not CLS-compliant I have dozens of webforms in the main project that reference the proxy class with no compile time complaints as this snippet shows: Imports System.Data Partial Class frmZipeee Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load And yet I have one webform (also in the root of the main project) which gives me the "not CLS-compliant" message but yet attempts to reference the proxy class just like the other ASPX files. I get the compile time warning on the line annoted by me with 'ERROR here.. Imports System.Data Partial Class frmHome Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee ERROR here Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load This makes no sense to me. The file with the warning is called frmHome.aspx.vb; all others in the project declare things the same way and have no warning. BTW, the webservice itself returns standard datatypes: integer, string, and dataset.

  • Incompatible type for argument 1 of 'setBounds'

    - by Brandon
    I am trying to do my own custom classes and learn C and Objective C. I'm recieving the error that there is an incompatible type for argument 1. I've defined a struct and class like this: typedef enum { kRedColor, kGreenColor, kBlueColor } ShapeColor; typedef struct { int x, y, width, height; } ShapeRect; @interface Shape : NSObject { ShapeColor fillColor; ShapeRect bounds; } - (void) setFillColor: (ShapeColor) fillColor; - (void) setBounds: (ShapeRect) bounds; - (void) draw; @end // Shape Then I import the Shape.h file(code above) and try and create a shape like this: id shapes[4]; // I'm different! ShapeRect rect0 = { 0, 0, 10, 30 }; shapes[0] = [Shape new]; [shapes[0] setBounds: rect0]; I get the error that setBounds is incompatible. For some reason it isn't looking at the Shape.h class for the setBounds method and it is instead looking at the default setBounds method? Is there something I'm doing wrong? Thanks!

  • Android: Associating Browser to File Type in App

    - by tekmunki
    I'm attempting to write a simple app that associates a file type to the browser; this is assuming the browser will open the file locally... If this doesn't work, the local file - editor will be fine. I have an option of auto-mailing .ELC files from a custom app, they are basically html formatted TEXT or TXT only files; I would like to associate the .elc extension so that it will open direct from mail rather than just "Save to SD Card" as a mail option. Here's the code I'm at right now; AndroidManifest.xml: ELCViewer.java: package com.tekmunki.ELCViewer; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class ELCViewer extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("ELC Viewer Installed! Now, when you receive the ELC files, they will open in the browser."); setContentView(tv); } } 1) How do I make the browser associated with the ELCViewer Activity? (Do I need to make a second activity, or can that all be done in the manifest?) 2) How do I make it persist after the app has been ran once?

  • Robotlegs: Warning: Injector already has a rule for type

    - by MikeW
    I have a bunch of warning messages like this appear when using Robotlegs/Signals. Everytime this command class executes, which is every 2-3 seconds ..this message displays below If you have overwritten this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message. Warning: Injector already has a rule for type "mx.messaging.messages::IMessage", named "". The command functions fine otherwise but I think I'm doing something wrong anyhow. public class MessageReceivedCommand extends SignalCommand { [Inject] public var message:IMessage; ...etc.. do something with message.. } the application context doesnt map IMessage to this command, as I only see an option to mapSignalClass , besides the payload is received fine. Wonder if anyone knows how I might either fix or suppress this message. I've tried calling this as the warning suggests injector.unmap(IMessage, "") but I receive an error - no mapping found for ::IMessage named "". Thanks Edit: A bit more info about the error Here is the signal that I dispatch to the command public class GameMessageSignal extends Signal { public function GameMessageSignal() { super(IMessage); } } which is dispatched from a IPushDataService class gameMessage.dispatch(message.message); and the implementation is wired up in the app context via injector.mapClass(IPushDataService, PushDataService); along with the signal signalCommandMap.mapSignalClass(GameMessageSignal, MessageReceivedCommand); Edit #2: Probably good to point out also I inject an instance of GameMessageSignal into IPushDataService public class PushDataService extends BaseDataService implements IPushDataService { [Inject] public var gameMessage:GameMessageSignal; //then private function processMessage(message:MessageEvent):void { gameMessage.dispatch(message.message); } } Edit:3 The mappings i set up in the SignalContext: injector.mapSingleton(IPushDataService); injector.mapClass(IPushDataService, PushDataService);

  • Changing type of object in a conditional

    - by David Doria
    I'm having a bit of trouble with dynamic_casting. I need to determine at runtime the type of an object. Here is a demo: include include class PersonClass { public: std::string Name; virtual void test(){}; //it is annoying that this has to be here... }; class LawyerClass : public PersonClass { public: void GoToCourt(){}; }; class DoctorClass : public PersonClass { public: void GoToSurgery(){}; }; int main(int argc, char *argv[]) { PersonClass* person = new PersonClass; if(true) { person = dynamic_cast(person); } else { person = dynamic_cast(person); } person-GoToCourt(); return 0; } I would like to do the above. The only legal way I found to do it is to define all of the objects before hand: PersonClass* person = new PersonClass; LawyerClass* lawyer; DoctorClass* doctor; if(true) { lawyer = dynamic_cast(person); } else { doctor = dynamic_cast(person); } if(true) { lawyer-GoToCourt(); } The main problem with this (besides having to define a bunch of objects that won't be use) is that I have to change the name of the 'person' variable. Is there a better way? (I am not allowed to change any of the classes (Person, Lawyer, or Doctor) because they are part of a library that people who will use my code have and won't want to change). Thanks, Dave

  • How to create anonymous objects of type IQueryable using LINQ

    - by Soham Dasgupta
    Hi, I'm working in an ASP.NET MVC project where I have created a two LinqToSQL classes. I have also created a repository class for the models and I've implemented some methods like LIST, ADD, SAVE in that class which serves the controller with data. Now in one of the repository classes I have pulled some data with LINQ joins like this. private HerculesCompanyDataContext Company = new HerculesCompanyDataContext(); private HerculesMainDataContext MasterData = new HerculesMainDataContext(); public IQueryable TRFLIST() { var info = from trfTable in Company.TRFs join exusrTable in MasterData.ex_users on trfTable.P_ID equals exusrTable.EXUSER select new { trfTable.REQ_NO, trfTable.REQ_DATE, exusrTable.USER_NAME, exusrTable.USER_LNAME, trfTable.FROM_DT, trfTable.TO_DT, trfTable.DESTN, trfTable.TRAIN, trfTable.CAR, trfTable.AIRPLANE, trfTable.TAXI, trfTable.TPURPOSE, trfTable.STAT, trfTable.ROUTING }; return info; } Now when I call this method from my controller I'm unable to get a list. What I want to know is without creating a custom data model class how can I return an object of anonymous type like IQueryable. And because this does not belong to any one data model how can refer to this list in the view.

  • C++ template type deduction problem

    - by hamishmcn
    motivation: I would like to create a utility class so that instead of having to write: if( someVal == val1 || someVal == val2 || someVal == val3 ) I could instead write: if( is(someVal).in(val1, val2, val3) ) which is much closer to the mathematical 'a is an element of (b,c,d)' and also would save on a lot of typing when the variable name 'someVal' is long. Here is the code I have so far (for 2 and 3 values): template<class T> class is { private: T t_; public: is(T t) : t_(t) { } bool in(const T& v1, const T& v2) { return t_ == v1 || t_ == v2; } bool in(const T& v1, const T& v2, const T& v3) { return t_ == v1 || t_ == v2 || t_ == v3; } }; However it fails to compile if I write: is(1).in(3,4,5); instead I have to write is<int>(1).in(3,4,5); Which isn't too bad, but it would be better if somehow the compiler could figure out that the type is int with out me having to explicitly specify it. Is there anyway to do this or I am stuck with specifying it explicitly?

  • Can I pass a non-generic type where a generic type is expected?

    - by Water Cooler v2
    I want to define a set of classes that collect and persist data. I want to call them either on-demand basis, or in a chain-of-responsibility fashion, as the caller pleases. To support the chaining, I have declared my interface like so: interface IDataManager<T, K> { T GetData(K args); void WriteData(Stream stream); void WriteData(T data, Stream stream); IDataCollectionPolicy Policy; IDataManager<T, K> NextDataManager; } But the T's and K's for each concrete types will be different. If I give it like this: IDataManager<T, K> NextDataManager; I assume that the calling code will only be able to chain types that have the same T's and K's. Is there a way I can have it chain any type of IDataManager? One thing that occurs to me is to have IDataManager inherit from a non-generic IDataManager like so: interface IDataManager { } interface IDataManager<T, K>: IDataManager { T GetData(K args); void WriteData(Stream stream); void WriteData(T data, Stream stream); IDataCollectionPolicy Policy; IDataManager NextDataManager; } Is this going to work?

  • Firing PropertyChanged event in a complex, nested type in WPF

    - by John
    Hey I have a question about the PropertyChanged vent firing in WPF whne it is used in a complex type. I have a class called DataStore and a list of Departments (an ObservableCollection), and each department again has a list of Products. Properties in the Product class that are changed also affect properties in the Department and DataStore class. How does each Product notify the Department it belongs to, and the DataStore (which is the mother class of all) that one or more of its properties have changed their values? Example: a product has a property NumberSoldToday and is bound. The Department has a property called TotalNumberOfProductsSold: public int TotalNumberOfProductsSold { get { int result = 0; foreach(Product p in this.products) result += p.NumberSoldToday; return result; } } And the data store has a property TotalProductsSold (for all departments): public int TotalProductsSold { get { int result = 0; foreach(Product p in this.deparments) result += p.TotalNumberOfProductsSold; return result; } } If all these properties are bound, and the innermost property changes, it must somehow notify that the value of the other 2 changed as well. How? The only way I can see this happening is to hook up the PropertyChanged event in each class. Th event must also fire when deleting, adding to the collection of products and deparments, respectively. Is there a better, more clever way to do this?

  • WCF operationcontract with List type unavailable in (Silverlight) client

    - by Dave
    This is the first time I have tried returning a List of data to a Silverlight client, so I'm having trouble getting the client to recognize this operationcontract. All others are fine. I have a method on the server called ReadOwFileData that needs to return a List. ReadOwFileDataCompletedEventArgs shows up in the Object Browser in the client, but not ReadOwFileDataAsync. What I want is similar to the tutorial here. The Dictionary collection type on the client is set to System.Collections.Generic.List. I tried deleting and recreating the service reference. Web.Config on the server is using basicHttpBinding. Here is the operationcontract on the server: [OperationContract] public List<OwFileData> ReadOwFileData(string OrderID) { DataClasses1DataContext db = new DataClasses1DataContext(); var dFileData = (from p in db.OwFileDatas where p.OrderID == OrderID select p).ToList(); List<OwFileData> x = new List<OwFileData>(dFileData); return x; } Incidently, this works fine: [OperationContract] public Customer GetShippingAndContactInfo(string login, string ordernum) { DataClasses1DataContext db = new DataClasses1DataContext(); Customer dInfo = (from p in db.Customers where p.Login == login select p).Single(); return dInfo; } I would like to read this data in the client and place it into an object I created called ObservableCollection. But that obviously can't happen until the client can see the method on the server. I do not know if this is an acceptable start, but this is what is on the client so far. The ReadOwFileDataAsync object is null: void populatefilesReceivedDataSource(string OrderID) { ArtUpload.ServiceReference1.UploadServiceClient client = new ArtUpload.ServiceReference1.UploadServiceClient(); var myList = client.ReadOwFileDataAsync(OrderID); // can I just itterate thru the list instead of 'binding' }

  • Context.Items.Add on an XML return type?

    - by Scott Schluer
    So I have the following code contained within an HttpModule in an application I've been asked to support: app.Context.Response.ContentType = "text/xml"; app.Context.Items.Add("IpixRoomId", ipixRoomId); app.Context.Items.Add("IpixId", ipixId); app.Context.Response.Cache.SetCacheability(HttpCacheability.NoCache); app.Context.RewritePath(rewriteUrl, true); What's the purpose of adding data to Context.Items when the content type is XML? EDIT: For clarification, I'm calling up this URL: http://website.com/virtualtour/1971/6284/panorama2flash.swf I assume the SWF file (I know very little about Flash) makes another call to http://website.com/virtualtour/config.xml. The code I pasted above only executes on calls to config.xml. So since it's only the SWF file and config.xml being requested from the server, I'm a little confused. Can the .SWF file have access to HttpContext.Current.Items? Other than the HttpModule, there is no .NET involved in the code, it's a straight request to the SWF file which triggers a call to config.xml but it seems that those Context.Items contain the data needed to make the SWF file display the right virtual tour. I'm just missing where that link happens. It can't happen in the XML, so maybe in Flash?

  • Set registry to control working dir when associating file-type with application

    - by John
    I'm using Inno for an installer, and I want to associate a file type with my app: Root: HKCR; Subkey: ".rpl"; ValueType: string; ValueName: ""; ValueData: "MyReplay"; Flags: uninsdeletevalue; Root: HKCR; Subkey: "MyReplay"; ValueType: string; ValueName: ""; ValueData: "Replay File"; Flags: uninsdeletekey; Root: HKCR; Subkey: "MyReplay\DefaultIcon"; ValueType: string; ValueName: ""; ValueData: "{app}\bin\MyApp.ico,0"; Flags: uninsdeletekey; Root: HKCR; Subkey: "MyReplay\shell\open\command"; ValueType: string; ValueName: ""; ValueData: """{app}\bin\MyApp.exe"" ""%1"""; Flags: uninsdeletekey; Right now, double-clicking a .rpl file launches the app, but the working dir appears to be where the .rpl file is located, so the app crashes as it can't load any data. Is it posible to set the registry to control the start/working dir for file associations as well as the app that is launched? Or does my app itself need to be able to work around this?
