• How do I properly register the Type Library of A VB.NET COM+ Component?

  - by k_Dank

  I am looking to upgrade legacy VB6 COM+ components to VB.NET components. I have seemingly upgraded one already, called EventPackage, which has one class, IEventListener. Another, TradeOrders, Implements EventPackage.IEventListener. When attempting to build TradeOrders, I get the following Errors/Warnings; Cannot load type library for reference "EventPackage". Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)) The referenced component 'EventPackage' could not be found. Type 'EventPackage.IEventListener' is not defined. In the .vbproj, I notice this reference <COMReference Include="EventPackage"> <Guid>{0D76C094-21A6-4E04-802B-6E539F7102D7}</Guid> <Lcid>0</Lcid> <VersionMajor>2</VersionMajor> <VersionMinor>0</VersionMinor> <WrapperTool>tlbimp</WrapperTool> </COMReference> When I search the registry for this Guid, I find nothing. When using GUIDs for similar COM+ objects, I find them in HKEY_CLASSES_ROOT\CLSID\{...}\TypeLib ("..." being the GUID of the other component). When I go to the registry key name corresponding to EventPackage.IEventListener, I find that there is no \TypeLib subkey. As you might suspect, searching the reg for "0D76C094-21A6-4E04-802B-6E539F7102D7" yields no results. So I know this must be a registry problem, But I have tried seemingly every google result I have found. I have tried Regasm and regsvcs .exe's to no avail. Many pages just tell me that dragging the dll to the COM+ manager should automatically register the component. So how do I register the Type library? Details on how I made EventPackage COM+ component Ran the VB6-VB.NET wizard Then I added some lines to the assemblyinfo.vb file added Imports System.EnterpriseServices added Imports System.EnterpriseServices Imports System.Data.SqlClient <Assembly: CLSCompliant(True)> <Assembly: AssemblyKeyFileAttribute("...")> for a strong name <Assembly: Guid("...")> (Where "..." is the COM+ CLSID of the old component) I added the following to the class file IEventListener.VB Imports System.EnterpriseServices <ComClass("...")> _ (Where ... is the proper COM+ CLSID, that is the only argument) Inherits ServicedComponent changed the ID made by the Conversion wizard to the proper value (from <System.Runtime.InteropServices.ProgId("IEventListener_NET.IEventListener)> to <System.Runtime.InteropServices.ProgId("EventPackage.IEventListener")> _ Then I dragged the DLL into the COM+ manager in the proper COM+ application (although, the "Path" is not specified and only says mscoree.dll)

• JPA EclipseLink Auditing for Oracle issue with SessionCustomizer...

  - by enrique

  I was trying to use the SessionCustomizer for auditing with v$session.program for oracle and it works with JDBC but i need it working with JPA, so i read a bit more the documentation for SESSION_CUSTOMIZER in this site: http://wiki.eclipse.org/Using_EclipseLink_JPA_Extensions_(ELUG)#EclipseLink_JPA_Persistence_Unit_Properties_for_Customization_and_Validation but had not lucky in making it work in passing the program name parameter to oracle with the v$session.program... i was using the SessionCustomizer and it is an interface so my code is as follows: package com.util; import org.eclipse.persistence.config.SessionCustomizer; import org.eclipse.persistence.sessions.Session; /** * * @author xkalibur */ public class ProgramCustomizer implements SessionCustomizer{ public void customize(Session s) throws Exception { s.getDatasourceLogin().setProperty("v$session.program","Customers"); } } then in CustomerFacade : ProgramCustomizer pc=new ProgramCustomizer(); public void edit(Customer customer) { emProperties.put(PersistenceUnitProperties.SESSION_CUSTOMIZER,pc); em=factory.createEntityManager(emProperties); em.merge(customer); } and returns the following error: javax.ejb.EJBException Caused by: java.lang.NullPointerException at com.facades.CustomerFacade.edit(CustomerFacade.java:48) please some help...

• c++ meaning of the use of const in the signature

  - by jbu

  Please help me understand the following signature: err_type funcName(const Type& buffer) const; so for the first const, does that mean the contents of Type cannot change or that the reference cannot change? secondly, what does the second const mean? I don't really even have a hint. Thanks in advance, jbu

  - by user3474542

  The objective of the method below is to delete the data from the database using entity framework. I am populating the subscriptions entity by passing two parameters and then calling the atttach and remove method of the context class. Bureau entities is the context class. using (BUREAUEntities bureauEntities = new BUREAUEntities()) { var subscription = new SubcriptionRepository().GetSusbcriptionBySubscriptionTypeId(subscriptionTypeId, companyId); bureauEntities.Subscriptions.Attach((DataAccessLayer.DatabaseModel.Subscription)subscription); bureauEntities.Subscriptions.Remove(subscription); bureauEntities.SaveChanges(); } I am getting the following error message at An entity object cannot be referenced by multiple instances of IEntityChangeTracker at line bureauEntities.Subscriptions.Attach((DataAccessLayer.DatabaseModel.Subscription)subscription); Could somebody tell me where am I going wrong ?

• Different ways to specify libraries to gcc/g++

  - by abigagli

  I'd be curious to understand if there's any substantial difference in specifying libraries (both shared and static) to gcc/g++ in the two following ways (CC can be g++ or gcc) CC -o output_executable /path/to/my/libstatic.a /path/to/my/libshared.so source1.cpp source2.cpp ... sourceN.cpp vs CC -o output_executable -L/path/to/my/libs -lstatic -lshared source1.cpp source2.cpp ... sourceN.cpp I can only see a major difference being that passing directly the fully-specified library name would make for a greater control in choosing static or dynamic versions, but I suspect there's something else going on that can have side effects on how the executable is built or will behave at runtime, am I right? Andrea.

• jquery updating a div in ajax diesnt work properly, when using a variable

  - by maschek

  hi, i got the following code var zieldiv = $(this).attr(\'id\'); $.ajax({ url: \'index.php?params\', type: \'POST\', data: { color:thenewcolor, zieldiv:zieldiv }, timeout: 50000, beforeSend: function() { $("#" + zieldiv).css({background: "#" + thenewcolor} ); } }); I use this for dragging a small div into a bigger div. the variable at the beginnning would give out the string "test1". So in the ajax.thing the css of a div which matches the var zieldiv should be updatet. Problem is, if i would place a string instead a var into the $(...) like $("#test1") it acts like its supposed to, the #test1 gets updated. but if i use the var $("#" + zieldiv) the parent div, which is surrounding the #test1-div gets updated. but i know for sure the var zieldiv contains the string "test1", because when passing it to php it contains "test1". so i think this is a little strange. do you have any ideas? thanx, maschek

• Using xsl param (if exists) to replcae attribute value

  - by Assaf

  I would like an xsl that replaces the value attribute of the data elements only if the relevant param names are passed. Input <applicationVariables applicationServer="tomcat"> <data name="HOST" value="localhost"/> <data name="PORT" value="8080"/> <data name="SIZE" value="1000"/> </applicationVariables> So for example if passing in a param HOST1=myHost and PORT=9080 the output should be: <applicationVariables applicationServer="tomcat"> <data name="HOST" value="myHost"/> <data name="PORT" value="9080"/> <data name="SIZE" value="1000"/> </applicationVariables> Note that HOST and PORT where replaced but SIZE was not replaced because there was no parameter with name SIZE Since the list of data elements is long (and may change), i would like a generic way of doing this with xsl

• What is the best method of assessment for computer science students?

  - by Gavimoss

  This question is a bit more philosophical so feel free to remove if you like but it's been bugging me for the last 4 years! As a final year student I find that exams can be often be passed with a couple of days of cramming, without necessarily retaining or understanding the content i.e. a regurgitation of lecture notes is often enough to gain high marks. A friend of mine is about to graduate with an honours degree whose final year evaluation was based solely on practical work (a project, assignment marks and the creation of a poster) yet all of this work could have been completed by a third party. Personally I don't think either of these methods of assessment is sufficient as I am currently on track for a 1st class honours in artificial intelligence and computer science and believe this is mostly due to my skill in passing exams not my skill as a programmer or my vast in depth knowledge of any of the subjects I have "studied". Surely there is a better way to assess our skills - isn't there?

• Avaudioplayer problem regarding song overlaping

  - by Ajeet Kumar Yadav

  The problem is in being able to catch the instance of the player to control it i.e. Stop it, Play it etc. The code by default creates multiple instances of the same player and overlaps the songs. I am being unable to reference the player specifically. Do you have an idea as to how we can do so? Thanks, Arun

• Function calls in virtual machine killing performance

  - by GenTiradentes

  I wrote a virtual machine in C, which has a call table populated by pointers to functions that provide the functionality of the VM's opcodes. When the virtual machine is run, it first interprets a program, creating an array of indexes corresponding to the appropriate function in the call table for the opcode provided. It then loops through the array, calling each function until it reaches the end. Each instruction is extremely small, typically one line. Perfect for inlining. The problem is that the compiler doesn't know when any of the virtual machine's instructions are going to be called, as it's decided at runtime, so it can't inline them. The overhead of function calls and argument passing is killing the performance of my VM. Any ideas on how to get around this?

• In node.js slow readable stream attached to a faster pushing message queue eats up memory

  - by Vishal

  In my node.js program I have a response stream attached to a message queue (zeromq) delivering data at a very high rate. Due to slow network connection the response stream and its underlying implementation is unable to consume data at that pace thus occupying a lot of memory. Do you have any suggestion to solve this problem. For reference please see the code snippet below: zmq.on("message", function(data) { res.write(data); // End response on some event });

• Why is the content of slice not changed in GO?

  - by Kid

  I thought that in GO language, slices are passed by reference. But why the following code doesn't change the content of slice c? Am I missing something? Thank you. package main import ( "fmt" ) func call(c []int) { c = append(c, 1) fmt.Println(c) } func main() { c := make([]int, 1, 5) fmt.Println(c) call(c) fmt.Println(c) } The result printed is: [0] [0 1] [0] while I was expecting [0] [0 1] [0 1]

• Mercurial: Share a repo without putting it on a server?

  - by Rosarch

  I am working in a student group with several other people. We would like to use Mercurial as our version control system, but some of our files can't be put online in a public hosting service like Google Projects or Codeplex. Is there some way that we can host a repo on our own machines, passing the files/changesets between each other as necessary, without creating a horribly conflicted mess? I know that Mercurial has a bundle command that can be used to package a repo. If I do that, and send the bundle someone else, and they want to get the changes back to me, what's the best way to do that? Send me a bundle back? I have a shared hosting account on a server. Is there any chance I could run Mercurial off that box? How would I find this out?

• HTML5 offline cache google font api

  - by Bala Clark

  I'm trying to create an offline HTML5 test application, and am playing with the new google fonts api at the same time. Does anyone have any ideas how to cache the remote fonts? Simply putting the api call in the cache manifest doesn't work, I assume this is because the api actually loads other files (ttf, eot, etc). Any ideas if using the font api offline would be possible? For reference this is the call I am making: http://fonts.googleapis.com/css?family=IM+Fell+English|Molengo|Reenie+Beanie

• Is there an image phase correlation library available for Python?

  - by kamasudra

  A project that involves image processing, i.e. to calculate the angular shift of the same image when shifted by a medium of certain Refractive Index. We have to build an app that correlates the 2 images (phase/2D correlation?) and then plot using Chaco and Mayavi (2 libraries in Python). Is there any other existing template software (FOSS) that we can base our app on, or use it as a reference?

• Is it bad practice to assign a css class for the sole purpose of finding it with jQuery?

  - by user187305

  I'm using ASP.NET, not the newest one with that clientIdMode stuff. So, the control ids are generated and funky. There are lots of ways of passing ids around, but lately I've been assigning a 'fake' css class to the control I'm interested in. Then in a js file I use jQuery to find the control. Is this bad practice? It seems a lot like the ajaxControlToolkit's behaviorId to me... Is the behaviorId bad practice as well?

• How do IOS know which viewController is being viewed and hence need viewWillAppear to be called

  - by Jim Thio

  How does iOs know? Does each view has a pointer to it's controller? What happened? When we pop a viewController from navigation, does the navigationController arrange which view should be called? For example: If I added: [[BNUtilitiesQuick window] addSubview:[BNUtilitiesQuick searchController].view]; viewWillAppear will be called. However, window doesn't know the viewController. I am passing the view outlet of the controller not the controller. How can iOs 5 knows that it has to call [[BNUtilitiesQuick searchController] viewWillAppear:YES]

• How to make Dajax callback into scoped object

  - by BozoJoe

  I cant seem to find a way to make django-dajaxice have its callback inside same scoped object from which made the initial call. MyViewport = Ext.extend(MyViewportUi, { initComponent: function() { MyViewport.superclass.initComponent.call(this); }, LoadRecordsCallback: function(data){ if(data!='DAJAXICE_EXCEPTION') { alert(data); } else { alert('DAJAXICE_EXCEPTION'); } }, LoadRecords: function(){ Dajaxice.Console.GetUserRecords(this.LoadRecordsCallback); } }); var blah = new MyViewport(); blah.LoadRecords(); I'm on django, and like the calling syntax to django-dajaxice. I'm using Extjs 3.2 and tried passing a Ext.createCallback but Dajax's returning eval seems to only want a string for the callback.
