    - by shikarishambu
    Hi, Is there a way to externalize report queries for BIRT reports. We need to support multiple database engines and so our queries are different depending on the underlying database. I would like to use a config parameter to tell BIRT report to use a specific query file

  • Upload images to fixed positions

    - by Stpapa
    Hello! I really need your help. I would like to ask if it is possible using flash to upload multiple images to particular positions. For example, I have a target that is called "people" and when someone uploads an image that is called "people" the image will be placed on that target. I apologize for my English. Thank you in advance.

  • Memcached for PHP 5.3

    - by Industrial
    Hi everyone, I have looked everywhere for some clues on how to run the Memcached extension in my WAMP windows development environment (thats right, the memcached with an D in the end, not memcache). I already use memcache (without the D), but it would be handy to take part of memcached's more extended multiple-server features. How can I get this up and running? Thanks

  • call a Javascript function from controller more than once (in Rails)

    - by mm1
    hi. I have a multiple file upload form(html5) and want to update my view as soon one of the images is transfered to my image server. Currently I upload the files with ajax and use response_to_parent to update my upload view when all images are transfered to the image server. Is it possible to call a Javascript function from the controller more than once per action? def upload params[:images].each do |file| upload_to_image_server(file) #page << Update upload View end end Thanks, Michael

  • Finding existing tickets before opening new ones on trac

    - by Jens Jansson
    We're using Trac as the task management tool at the project we work in. However, Trac search is maybe not the most intuitive search out there, and we end up having multiple duplicates as the reporters can't effectively find if there already is a reported ticket of the question he or she found. Stack Overflow's "Related Questions" concept is great and works magnificently! I was wondering if someone has heard of some similar plugin to Trac, or if you have solved this problem some other way.

  • Android Device Management

    - by Jon Hopkins
    I'm looking at the possibility of using Android as a secure corporate mobile platform. One of the pre-requisites for this will be a way of managing multiple devices, security policies, software deployment, that sort of thing - essentially the things the BlackBerry Enterprise Server handles for BlackBerry or MDM (or something 3rd party like SOTI) handles for Windows Mobile. Does such a thing exist for Android? It's a platform we're interested in but without this right now (and we're not in a position to build it ourselves) it's a non-starter.

  • Get information from a higher class?

    - by Clint Davis
    I don't know really how to word the question so please bear with me... I have 3 classes: Server, Database, and Table. Each class has a "Name" property. How I want it to work is that each server can have multiple databases and each database can have multiple tables. So in the Server class I have this property. Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property And I have something similar in the Database class for the tables. This works fine now because I can do something like this to get all the databases in the server. For Each db In s.Databases 's being the server object Debug.Print(db.Name) Next I would like to expand these classes. I want the server class to handle all the connection information and I would like the other classes to use the server class's connection information in them. For example, I setup a server class and set the connection string to the server. Then I want the database class to use serverclass.connectionstring property to connect to the server and get a list of all the databases. But I want to keep that code in the database class. How can I do this? I've attached some code of what I want to do. Public Class Server Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property End Class '-----New class Public Class Database Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _tables As List(Of Table) Public Property Tables() As List(Of Table) Get Return _tables End Get Set(ByVal value As List(Of Table)) _tables = value End Set End Property 'This is where I need help! Private Sub LoadTables () dim connectionstring as string = server.connectionstring 'Possible? 'Do database stuff End Class Thanks for reading!

  • Using Entity Framework V4 - Mapping Stored Procedures with XML output

    - by ericwahner
    I have been attempting to implement the Entity framework into my project and unfortunately it seems like mapping an XML result set from SQL is not something that is supported. I also have issues with returning multiple result sets, though I understand that the EFExtensions was created to try to mitigate that issue. Is there a way to take a FOR XML EXPLICIT result from a SQL Stored Procedure and map it using the Entity Framework?

  • Features to remove from C++

    - by Justin Ethier
    This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.

  • How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

    - by Zack
    I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?

  • Doctrine 1.2: Can a model have two instances of the sluggabl behavior?

    - by prodigitalson
    I dont see any direct mention on using multiple slugs (or any behavior for that matter) for single model. Is there a way to use the sluggable behavior to generate two separate slugs for a model? For example i need to generate two slugs for every record a product_id consisting of a slugified company name and sku and a distributor_id consisting of a different slugified company name. Obviously i could write this myself fairly easily, im just wondering if this can be done quickly with Sluggable.
