  • Java desktop app: How to maximize tray application when hotkey pressed?

    - by David
    I need to write a program that, when minimized, lives in the System Tray, and I'll use Java 6's SystemTray API to do that. How can I make that application comes to the foreground when the user presses some hotkey? For example, the app is running but minimized. When the user presses CTRL-SHIFT-Y or something (or, like Google Desktop's search, CTRL twice) and the application is maximized. EDIT: I know about how to bring a Java window to the foreground. I'm asking more specifically about how to make a running Java app listen for a hotkey.

  • Logic for family tree program

    - by david robers
    Hi All, I am creating a family tree program in Java, or at least trying to. I have developed several classes: Person - getters and setter for name gender age etc FamilyMember - extends Person getters and setters for setting arents and children Family - which consists of multiple family members and methods for adding removing members FamilyTree which is the main class for setting relationships. I have two main problems: 1) I need to set the relationships between people. Currently I am doing: FamilyMember A, FamilyMember B B.setMother(A); A.setChild(B); The example above is for setting a mother child relationship. This seems very clunky. Its getting very long winded to implement all relationships. Any ideas on how to implement multiple relationships in a less prodcedural way? 2) I have to be able to display the family tree. How can I do this? Are there any custom classes out there to make life easier? Thanks for your time...

  • A follow up on type coercion in C++, as it may be construed by type conversion

    - by David
    This is a follow up to my previous question. Consider that I write a function with the following prototype: int a_function(Foo val); Where foo is believed to be a type defined unsigned int. This is unfortunately not verifiable for lack of documentation. So, someone comes along and uses a_function, but calls it with an unsigned int as an argument. Here the story takes a turn. Foo turns out to actually be a class, which can take an unsigned int as a single argument of unsigned int in an explicit constructor. Is it a standard and reliable behavior for the compiler to render the function call by doing a type conversion on the argument. I.e. is the compiler supposed to recognize the mismatch and insert the constructor? Or should I get a compile time error reporting the type mismatch.

  • Clickonce redirect

    - by David Hagan
    Is it possible to deploy an application (using an existing clickonce deployment URL, such that users update to that version) which changes the deployment URL of the deployed application? The scenario is that I have a deployed client (A), which is stable and has been in use for over a year, and a new client (B), which is in development and will be used. However, B and A have different UIDs so that they can both be deployed on the same system together. At some point in the future, I'd like to automatically migrate users who have been using A to B, but I'd hope that Clickonce is well-designed enough to not upgrade A to B if I place B's install files in A's install directory (because it should be checking those UIDs). I know that a C# application that's been deployed through clickonce has some access to its own deployment method, and I'm wondering whether I'm able to change the upgrade-location. I'm hoping to do this quietly without much involvement of the user (and I understand that quiet redirects are heavily frowned upon, for good reasons) and am wondering whether anyone has any experience of trying to modify an installed clickonce's deployment/upgrade information with an update.

  • PHP Doesn't Display Errors or Warnings.

    - by David
    I don't know how php.ini was configured since I don't have access to it. But on top of my php code file I have error_reporting(E_ALL); ini_set('display_errors', '1'); But still, if there is an error, e.g. missing a ")", the page is blank. It is so painful to debug without error message. Why were the errors not shown?

  • Observer Design Pattern - multiple event types

    - by David
    I'm currently implementing the Observer design pattern and using it to handle adding items to the session, create error logs and write messages out to the user giving feedback on their actions (e.g. You've just logged out!). I began with a single method on the subject called addEvent() but as I added more Observers I found that the parameters required to detail all the information I needed for each listener began to grow. I now have 3 methods called addMessage(), addStorage() and addLog(). These add data into an events array that has a key related to the event type (e.g. log, message, storage) but I'm starting to feel that now the subject needs to know too much about the listeners that are attached. My alternative thought is to go back to addEvent() and pass an event type (e.g. USER_LOGOUT) along with the data associated and each Observer maintains it's own list of event handles it is looking for (possibly in a switch statement), but this feels cumbersome. Also, I'd need to check that sufficient data had also been passed along with the event type. What is the correct way of doing this? Please let me know if I can explain any parts of this further. I hope you can help and see the problem I'm battling with.

  • Are Multi-column Primary Keys in MySQL a optimisation problem?

    - by David
    Been looking into using multi-column primary keys and as performance is extremely important with the size of traffic and database I need to know if there is anything to consider before I start throwing out the unique ID method on many of my tables and start using mulit column primary keys. So, what are the performance/optimisation pros/cons to using multi column primary keys versus a basic single column, auto-inc primary key?

  • Loose Coupling of Components

    - by David
    I have created a class library (assembly) that provides messaging, email and sms. This class library defines an interface IMessenger which the classes EmailMessage and SmsMessage both implement. I see this is a general library that would be part of my infrastructure layer and would / can be used across any development. Now, in my application layer I have a class that requires to use a messaging component, I obviously want to use the messaging library that I have created. Additionally, I will be using an IoC container (Spring.net) to allow me to inject my implementation i.e. either email or sms. Therefore, I want to program against an interface in my application layer class, do I then need to reference my message class library from my application layer class? Is this tightly coupling my application layer class to my message class library? Should I be defining the interface - IMessenger in a seperate library? Or should I be doing something else?

  • Possible to capture all events in a web browser?

    - by David
    I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.

  • SQL 2005 w/ C# optimal "Paging"

    - by David Murdoch
    When creating a record "grid" with custom paging what is the best/optimal way to query the total number of records as well as the records start-end using C#? SQL to return paged record set: SELECT Some, Columns, Here FROM ( SELECT ROW_NUMBER() OVER (ORDER BY Column ASC) AS RowId, * FROM Records WHERE (...) ) AS tbl WHERE ((RowId > @Offset) AND (RowId <= (@Offset + @PageSize)) ) SQL to count total number of records: SELECT COUNT(*) FROM Records WHERE (...) Right now, I make two trips to the server: one for getting the records, and the other for counting the total number of records. What is/are the best way(s) to combine these queries to avoid multiple DB trips?

    - by David
    For example, I have an ASP.NET form that is called by another aspx: string url = "http://somewhere.com?P1=" + Request["param"]; Response.Write(url); I want to do something like this: string url = "http://somewhere.com?P1=" + Request["param"]; string str = GetResponse(url); if (str...) {} I need to get whatever Response.Write is getting as a result or going to url, manipulate that response, and send something else back. Any help or a point in the right direction would be greatly appreciated.

  • Using Qt's XML library for simple operation

    - by David Powers
    I basically want to use the XML parser from Qt in my existing project. I have only used Qt once before, and that was with Qt Designer, and I am not having much luck finding anything on Google about how to just use the XML library. I have downloaded a web page that has one large list, and I want to parse it and add each list item to a c++ list. I found this sample code on Ubuntu forums... http://www.uluga.ubuntuforums.org/showpost.php?p=9112973&postcount=6 I want to use that except I need to know what exactly I need to add to the project to get access to it. One other small question is QDomDocument seems to be for files (makes sense) but I have the XML in a string. What part of the XML library works for contents of a string?

  • How do I create a SQL Server 2008 Reporting Services Template to a Default Font?

    - by David Stein
    I'm creating a new template to create reports from at a later date. I know how to create one, and I know where to save it. However, the problem is this. Everything that is created on the report uses the default font of Arial with a size of 10pt. I need to set mine to default to Tahoma 11pt. I can create a mock title, mock tables, etc and save those to Tahoma 11pt, but any new controls that are used on any version of this report will default back to Arial 10pt. How do I fix this?

  • Setting Scala "Platform" for NetBeans 6.8 on Ubuntu Lucid Lynx

    - by David
    I'm trying to use NetBeans 6.8 with Scala, and it can't find the "Scala Platform" (whatever that is supposed to be). I'm using Ubuntu Lucid Lynx (fully updated). The libraries are in /usr/share/java, the binaries in /usr/bin, the docs in /usr/share/doc/scala-doc/, and the sources are uninstalled. I think that NetBeans is looking for Scala to be in one single directory (with bin, lib, etc.). I created /usr/share/scala and placed links to the other directories, but it still didn't quite make it. Can someone straighten me out? (And why is it a "platform"? More needless jargon...)

  • ServicedComponent not being disposed in finaliser

    - by David Gray Wright
    Questions needing answers : Does the finalizer of the client side ServicedComponent call ServicedComponent.DisposeObject or Dispose? How should destruction (release of memory) occur in the com server in realtion to its usage in the client? Basically - we are reaching a 2 gig limit on process size (memory) of the COM server as memory is not being released - is the solution to call explicitly call Dispose or use the using statement in the client?

  • PostgreSQL: Why does this simple query not use the index?

    - by David
    I have a table t with a column c, which is an int and has a btree index on it. Why does the following query not utilize this index? explain select c from t group by c; The result I get is: HashAggregate (cost=1005817.55..1005817.71 rows=16 width=4) -> Seq Scan on t (cost=0.00..946059.84 rows=23903084 width=4) My understanding of indexes is limited, but I thought such queries were the purpose of indexes.

  • Prove that the set of regular languages is a proper subset of the set of the context-free languages

    - by David Relihan
    I was brushing up (not homework)on some computation-theory and came accross this problem: How can you prove that the set of regular languages is a proper subset of the set of the context-free languages. Now I know a language is regular iff it is accepted by a finite automaton. And I know a language is context-free iff it is accepted by a pushdown automaton. But I'm not sure of what solution is.

  • Entity Framework 4 and SQL Compact 4: How to generate database?

    - by David Veeneman
    I am developing an app with Entity Framework 4 and SQL Compact 4, using a Model First approach. I have created my EDM, and now I want to generate a SQL Compact 4.0 database to act as a data store for the model. I bring up the Generate Database Wizard and click the New Connection button to create a connection for the generated file. The Choose Data Source dialog appears, but SQL Compact 4.0 is not listed in the list of available data sources: I am running VS 2010 SP1 (beta) and I have installed the VS 2010 Tools for SQL Compact 4.0. I can create a SQL Compact 4.0 data connection from the Server Explorer. It is only in the Generate Database Wizard that the 4.0 option doesn't appear. BTW, my SQL Compact 4.0 installation does include System.Data.SqlServerCe.Entity.dll. So I should have the SQL Compact components I need. Am I doing something incorrectly, or is this a bug? Does anyone have a fix or a workaround? Thanks for your help.
