Taking Jeff Atwood's [advice](http://www.codinghorror.com/blog/archives/001163.html), I decided to use a JavaScript library for the very basic to-do list application I'm writing. I picked the [Dojo toolkit](http://dojotoolkit.org/), version 1.1.1. At first, all was fine: the drag-and-drop code I wrote worked first time, you can drag tasks on-screen to change their order of precedence, and each drag-and-drop operation calls an event handler that sends an AJAX call to the server to let it know that order has been changed.
Then I went to add in the email tracking functionality. Standard stuff: new incoming emails have a unique ID number attached to their subject line, all subsequent emails about that problem can be tracked by simply leaving that ID number in the subject when you reply. So, we have a list of open tasks, each with their own ID number, and each of those tasks has a time-ordered list of associated emails. I wanted the text of those emails to be available to the user as they were looking at their list of tasks, so I made each task box a Dijit "Tree" control - top level contains the task description, branches contain email dates, and a single "leaf" off of each of those branches contains the email text.
First problem: I wanted the tree view to be fully-collapsed by default. After searching Google quite extensively, I found a number of solutions, all of which seemed to be valid for previous versions of Dojo but not the one I was using. I eventually figured out that the best solution would seem to be to have a event handler called when the Tree control had loaded that simply collapsed each branch/leaf. Unfortunately, even though the Tree control had been instantiated and its "startup" event handler called, the branches and leaves still hadn't loaded (the data was still being loaded via an AJAX call). So, I modified the system so that all email text and Tree structure is added server-side. This means the whole fully-populated Tree control is available when its startup event handler is called.
So, the startup event handler fully collapses the tree. Next, I couldn't find a "proper" way to have nice formatted text for the email leaves. I can put the email text in the leaf just fine, but any HTML gets escaped out and shows up in the web page. Cue more rummaging around Dojo's documentation (tends to be out of date, with code and examples for pre-1.0 versions) and Google. I eventually came up with the solution of getting JavaScript to go and read the SPAN element that's inside each leaf node and un-escape the escaped HTML code in it's innerHTML. I figured I'd put code to do this in with the fully-collapse-the-tree code, in the Tree control's startup event handler.
However... it turns out that the SPAN element isn't actually created until the user clicks on the expando (the little "+" symbol in a tree view you click to expand a node). Okay, fair enough - I'll add the re-formatting code to the onExpand() event handler, or whatever it's called. Which doesn't seem to exist. I've searched to documentation, I've searched Google... I'm quite possibly mis-understanding Dojo's "publish/subscribe" event handling system, but I think that mainly because there doesn't seem to be any comprehensive documentation for it anywhere (like, where do I find out what events I can subscribe to?).
So, in the end, the best solution I can come up with is to add an onClick event handler (not a "Dojo" event, but a plain JavaScript event that Dojo knows nothing about) to the expando node of each Tree branch that re-formats the HTML inside the SPAN element of each leaf. Except... when that is called, the SPAN element still doesn't exist (sometimes - other times it's been cached, just to further confuse you). Therefore, I have the event handler set up a timer that periodically calls a function that checks to see if the relevant SPAN element has turned up yet before then re-formatting it.
// An event handler called whenever a "email title" tree node is expanded.
function formatTreeNode(nodeID) {
if (dijit.byId(nodeID).getChildren().length != 0) {
clearInterval(nodeUpdateIntervalID);
messageBody = dijit.byId(nodeID).getChildren()[0].labelNode.innerHTML
if (messageBody.indexOf("<b>Message text:</b>") == -1) {
messageBody = messageBody.replace(/>/g, ">");
messageBody = messageBody.replace(/</g, "<");
messageBody = messageBody.replace(/&/g, "&");
dijit.byId(nodeID).getChildren()[0].labelNode.innerHTML = "<b>Message text:</b><div style=\"font-family:courier\">"+messageBody+"</div>";
}
}
}
// An event handler called when a tree node has been set up - we changed the default fully-expanded to fully-collapsed.
function setupTree(theTree) {
dijit.byId("tree-"+theTree).rootNode.collapse();
messageNode = dijit.byId("tree-"+theTree).rootNode.getChildren();
for (pl = 0; pl < messageNode.length; pl++) {
messageNode[pl].collapse();
messageNode[pl].expandoNode.onclick = eval("nodeUpdateIntervalID = setInterval(\"formatTreeNode('"+messageNode[pl].id+"')\",200); formatTreeNode('"+messageNode[pl].id+"');");
}
}
The above has the feel of a truly horrible hack, and I feel sure I must have taken a wrong turn somewhere early on in my thought process. Can someone please tell me:
* The correct way to go about putting nicely-formatted text inside a Dojo/Dijit Tree control.
* The correct way to handle Dojo events, like where I can figure out what events are available for me to subscribe to.
* A better JavaScript library to use (can I do what I want to with JQuery and avoid the all-around-the-houses approach seen above?).

Here's my prior research into this question:
The [Indy][1] components seem entirely synchronous. On the other hand, while ScktComp unit does use WSAAsyncSelect, it basically only asynchronizes a BSD-style multiplexed socket app. You get dumped in a single event callback, as if you had just returned from select() in a loop, and have to do all the state machine navigation yourself.
The .NET situation is considerably nicer, with Socket.BeginRead / Socket.EndRead, where the continuation is passed directly to Socket.BeginRead, and that's where you pick back up. A continuation coded as a closure obviously has all the context you need, and more.

I am torn. It was a design decision to leave such a flexible pre-processor out of C#. However, an author I highly respect mentions it may be ok in some circumstances.

After three years, our project to migrate a codebase to a new platform (a project I was on for 1.5 years, but my team lead was on for only a few months) went live. He, along with senior management of both my company and the client (I'm one of those god-awful consultants you hear so much about. My engagement is an "Application Outsourcing") declared the project to be a success. I disagreed, stating that old presentations I had found showed that compared to the original schedule, the delay in deployment was best measured in months and could potentially be measured in years. I explained what I know of project failure, and the studies and statistics behind failure rates. He responded that that was all academia, and that no project he led had failed, thanks to the wonders of change/risk management - what seems to come down to explaining delays and re-evaluating the schedule based on new data.
Maybe consulting like this differs from other projects, but it seems like this is just failure wrapped up in a prettier name to avoid the stigma of having failed to deliver on time, on budget, or with full functionality. The fact that he explained that my company gave away hours of work for free in order to finish the project within the maxed out budget says a lot.
So I ask you this:
* What is change management, and how does it apply to a project?
* Where does "change management" end, and "project failure" begin?

Some thoughts I've had were:
- **Roll my own serializer using DataOutputStream**: This would give me the greatest control of what was in the file, but at the cost of micromanaging it.
- **Straight old Serialization using ObjectOutputStream and its various related classes**: I'm not sold on it though since I find the data brittle. Changing any object's structure breaks the serialized instances of it. So I'm locked in to what seems to be a horrible versioning nightmare.
- **XML Serialization**: It's not as brittle, but it's significantly slower that straight out serialization. It can be transformed outside of my program.
- **JavaDB**: I'd considered this since I'm comfortable writing JDBC applications. The difference here is that the database instance would only persist while the file was being opened or saved. It's not pretty but... it does lend itself to migrating to a central server architecture if the need arises later and it introduces the possibility of quering the datamodel in a simpler way.
I'm curious to see what other people think. And I'm hoping that I've missed some obvious, and simpler approach than the ones above.
Thanks in advance,

At any point while editing the data in the form the user can click one of the buttons on the form to perform certain actions. By default the focus goes to the clicked button so the user has to click back on to the control they want to edit in order to continue modifying the data on the form. What I need to be able to do is return the focus to the last edited control after the button click event has been processed. Here's a sample screenshot that illustrates what I'm talking about:

The user can be entering data in textbox1, textbox2, textbox3, etc and click the button. I need the button to return the focus back to the control that most recently had the focus before the button was clicked.
I'm wondering if anyone has a better way of implementing this functionality than what I've come up with. Here's what I'm doing right now:

_lastEnteredControl = (Control)sender;
}

{

_lastEnteredControl.Focus();
}
}
So basically what we have here is a class variable that points to the last entered control. Each textbox on the form is setup so the textBox_Enter method is fired when the control receives the focus. Then, when the button is clicked focus is returned to the control that had the focus before the button was clicked.

Recently, I am running into "java.lang.OutOfMemoryError: Java heap space" error because I am not being conservative on memory usage. The user can open unlimited number of files, and the program keeps the opened objects in the memory. After a quick research I found [Ergonomics in the 5.0 Java Virtual Machine][1] and others saying on Windows machine the JVM defaults max heap size as 64MB.
Given this situation, how should I deal with this constraint?
I could increase the max heap size using command line option to java, but that would require figuring out available RAM and writing some launching program or script. Besides, increasing to some finite max does not ultimately get rid of the issue.
I could rewrite some of my code to persist objects to file system frequently (using database is the same thing) to free up the memory. It could work, but it's probably a lot work too.
If you could point me to details of above ideas or some alternatives like automatic virtual memory, extending heap size dynamically, that will be great.

I'm exploring the possibility of writing an application in Erlang, but it would need to have a portion written in Cocoa (presumably Objective-C). I'd like the front-end and back-end to be able to communicate easily. How can this best be done?
I can think of using C ports and connected processes, but I think I'd like a reverse situation (the front-end starting and connecting to the back-end). There are named pipes (FIFOs), or I could use network communications over a TCP port or a named BSD socket. Does anyone have experience in this area? | 0 |

What I'm trying to do though is create a class that could represent an arbitrarily large binary number and be able to perform simple arithmetic operations on two of them (add/subtract/multiply/divide).
My target is dealing with 128-bit integers.
There's a couple of approaches I'm looking at, and problems I see with them. Any input or commentary on what you would choose and how you might go about it would be greatly appreciated.
**Approach #1:** Create a 128-bit integer class that stores its integer internally as four 32-bit integers. The only problem with this approach is that I'm not sure how to go about handling overflow/underflow issues when manipulating individual chunks of the two operands.
**Approach #2:** Use the bcmath extension, as this looks like something it was designed to tackle. My only worry in taking this approach is the scale setting of the bcmath extension, because there can't be any rounding errors in my 128-bit integers; they must be precise. I'm also worried about being able to eventually convert the result of the bcmath functions into a binary string (which I'll later need to shove into some mcrypt encryption functions).
**Approach #3:** Store the numbers as binary strings (probably LSB first). Theoretically I should be able to store integers of any arbitrary size this way. All I would have to do is write the four basic arithmetic functions to perform add/sub/mult/div on two binary strings and produce a binary string result. This is exactly the format I need to hand over to mcrypt as well, so that's an added plus. This is the approach I think has the most promise at the moment, but the one sticking point I've got is that PHP doesn't offer me any way to manipulate the individual bits (that I know of). I believe I'd have to break it up into byte-sized chunks (no pun intended), at which point my questions about handling overflow/underflow from Approach #1 apply. | php | integer | null | null | null | null | open | Arithmetic with Arbitrarily Large Integers in PHP

In order to make the exception processing as generic as possible, and therefore to allow us to use it for any BizTalk application, our XML error schema includes an xs:any node, into which we can place a variety of data, depending on the actual exception. The generated XML should then be presented to a user through an InfoPath 2003 form for manual intervention before being represented back to BizTalk.
The problem is that InfoPath 2003 doesn't like schemas with an xs:any node. What we'd really like to do is the show the content of the exception report in a form with all relevant parameters mapped , and the entire content of the xs:any node in a text box, since users who are able to see these messages will be conversant with XML. Unfortunately, I am unable to make InfoPath even load the schema at design time.
Does anyone have any recommendation for how to achieve what we need, please?

The plugin works like this: Whenever I open a source file I let the plugin parse the source's corresponding build file (this could be further developed with caching the parse result). Getting the file is simple enough:
public void showSelection(IWorkbenchPart sourcePart) {
// Gets the currently selected file from the editor
IFile file = (IFile) workbenchPart.getSite().getPage().getActiveEditor()
.getEditorInput().getAdapter(IFile.class);
if (file != null) {
String path = file.getProjectRelativePath();
/** Snipped out: Rip out the source path part
* and replace with build path
* Then parse it. */
}

The problem I have is I have to use **hard coded strings** for the paths where the source files and build files go. Anyone know how to retrieve the build path from Eclipse?

===
I'm writing a plugin that will parse a bunch of files in a project. But for the moment I'm stuck searching through the Eclipse API for answers.
The plugin works like this: Whenever I open a source file I let the plugin parse the source's corresponding build file (this could be further developed with caching the parse result). Getting the file is simple enough:
public void showSelection(IWorkbenchPart sourcePart) {
// Gets the currently selected file from the editor
IFile file = (IFile) workbenchPart.getSite().getPage().getActiveEditor()
.getEditorInput().getAdapter(IFile.class);
if (file != null) {
String path = file.getProjectRelativePath();
/** Snipped out: Rip out the source path part
* and replace with build path
* Then parse it. */
}
}

The real thing is, I'm struggling to get my head around how to unit-test the UI and more generally objects that generate events: user controls, asynchronous database operations, etc.
So much of my code relates to UI events that I can't quite see how to even start the unit testing.
There must be some primers and starter docs out there? Some hints and tips?
I'm generally working in C# (2.0 and 3.5) but I'm not sure that this is strictly relevant to the question. | 0 |
