However, after implementing this I found out that many of the variable names have periods (.) in them. I have found this work arround: `Object.send('variable.name=', 'new value')`. However, I am wondering is there a way to escape the period so that I can use `Object.variable.name= 'new value'`?
Thanks,

I am working on a winforms application using LINQ to SQL - and am building the app using a SQL Express instance on my workstation. The final installation of the project will be on a proper SQL Server 2005.
The database has the same name, and all tables are identical but the hostname is different. The only way I have found to make it work from one machine to the next is to delete all of the objects from my .mdbl, save the project, connect to the other server, drag all of the references back on, and rebuild...
What's the correct way of making LINQ to SQL apps use a new database without rebuilding in visual studio?

I have a page that pulls dynamic content from a javabean and passes the list of objects to a custom tag for processing into html. Within each object is a bunch of html to be output that contains a second custom tag that I would like to also be rendered. The problem is that the tag invocation is rendered as plaintext.
An example might serve me better.
1 Pull information from a database and return it to the page via a javabean. Send this info to a custom tag for outputting.

<c:forEach var="noticeBean" items="${ImportantNoticeBean.importantNotices}"> <%-- Get the info --%>
<mysite:notice importantNotice="${noticeBean}"/> <%-- give it to the tag for processing --%>
</c:forEach>
this tag should output a box div like so
*SNIP* class for custom tag def and method setup etc
out.println("<div class=\"importantNotice\">");
out.println(" " + importantNotice.getMessage());
out.println(" <div class=\"importantnoticedates\">Posted: " + importantNotice.getDateFrom() + " End: " + importantNotice.getDateTo()</div>");
out.println(" <div class=\"noticeAuthor\">- " + importantNotice.getAuthor() + "</div>");

Some details:
- I am looking for solution for the entire page.
- When minimizing window, scrolling should appear only when all white space is gone.
In other words, width of screen should be represented as:
"leftSpace width=(screenWidth-widthOfCenteredElement)/2"+
"centeredElement width=widthOfCenteredElement"+
"rightSpace width=(screenWidth-widthOfCenteredElement)/2"
And the same for the height:
"topSpace height=(screenHeight-heightOfCenteredElement)/2"+
"centeredElement height=heightOfCenteredElement"+
"bottomSpace height=(screenWidth-heightOfCenteredElement)/2"
- By practical I mean that use of tables is OK. I intend to use this layout mostly for special pages like login. So CSS purity is not so important here, while following standards is desirable for future compatibility.

We have a .Net 2.0 application which is has a MySQL backend. We want to be able to deploy MySQl and the DB when we install the application and im trying to find the best solution. The current setup is to copy the required files to a folder on the local machine and then perform a "NET START" commands to install and start the mysql service. Then we restore a backup of the DB to this newly created mysql instance using bat files. Its not an ideal solution at all and im trying ton come up with something more robust.
The issues are User rights on Vista, and all sorts of small things around installing and starting the service. Its far too fragile to be reliable or at least it appears that way when i am testing it. This is a Client/Server type setup so we only need to install one Server per office but i want to make sure its as hassle free as possible and with as few screens as possible.
How would you do it?

Many people do suggest obfuscator but they just do rename classes / methods / fields with tough to remember character sequences but what about sensitive constant values ?
For example, you have developed the encryption / decryption component based on Password Based encryption technique. Now in this case any average Java person can use JAD (http://www.kpdus.com/jad.html) to decompile the class file and easily retrieve the password value (defined as constant) as well as SALT and in turn can decrypt the data by writing small independent program !
Or you suggest to build such sensitive components in Native code (e.g. VC++) and call them via JNI.

<p>We have a couple of large solutions, each with about 30 individual projects (class libraries and nested websites). It takes about 2 minutes to do a full rebuild all.</p>
A couple of specs on the system:
* Visual Studio 2005, C#
* Primary project is a Web Application Project
* 40 projects in total (4 Web projects)
* We use the internal VS webserver
* We extensively use user controls, right down to a user control which contains a textbox
* We have a couple of inline web projects that allows us to do partial deployment
* About 120 user controls
* About 200.000 lines of code (incl. HTML)
* We use Source Safe
<p>What I would like to know is how to bring down the time it takes when hitting the site with a browser for the first time. And, I'm not talking about post full deployment - I'm talking about doing a small change in the code, build, refresh browser.<br>
<br>
This first hit, takes about 1 minute 15 seconds before data gets back. </p>
<p>To speed things up, I have experimented a little with Ram disks, specifically changing the <compilation> attribute in web.config, setting the tempDirectory to my Ram disk.
This does speed things up a bit. Interestingly though, this totally removed ALL IO access during first hit from the browser.</p>
<b>Remarks</b><br>
We never do a full compile during development, only partial. For example, the class library being worked on is compiled and then the main site is compiled which then copies the binaries from the class library to the bin directory).
I understand that the asp.net engine needs to parse all the ascx/aspx files after critical files have been changed (bin dir for example) but, what I don't understand is why it needs to do that when only <i>one</i> library dll has been modified.
So, anybody know of a way to either:
Sub segment the solutions to provide faster first hit or fine tune settings in config files or something.
And, again: I'm only talking about development, NOT production deployment, so doing the pre-built compile option is not applicable.
Thanks, Ruvan

I am using it to show a new div with a list gathered from a database when a button is pressed. The problem is the button needs to do a postback to get this list as I don't want to make the call to the database unless it's needed. The postback however stops the animation mid flow and resets it. The button is within an update panel.
Ideally I would want the animation to start once the postback is complete and the list has been gathered. I have looked into using the ScriptManager to detect when the postback is complete and have made some progress. I have added two javascript methods to the page.
function linkPostback() {
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(playAnimation)
}
function playAnimation() {
var onclkBehavior = $find("ctl00_btnOpenList").get_OnClickBehavior().get_animation();
onclkBehavior.play();
}
And I’ve changed the btnOpenList.OnClientClick=”linkPostback();”
This almost solves the problem. I’m still get some animation stutter. The animation starts to play before the postback and then plays properly after postback. Using the onclkBehavior.pause() has no effect. I can get around this by setting the AnimationExtender.Enabled = false and setting it to true in the buttons postback event. This however works only once as now the AnimationExtender is enabled again. I have also tried disabling the AnimationExtender via javascript but this has no effect.
Is there a way of playing the animations only via javascript calls? I need to decouple the automatic link to the
buttons click event so I can control when the animation is fired.
Hope that makes sense.
Thanks

PDF allows documents to be encrypted so that either a user password and/or an owner password is required to do various things with the document (display, print, etc). A common use is to lock a PDF so that end users can read it without entering any password, but a password is required to do anything else.
I'm trying to parse PDFs that are locked in this way (to get the same privileges as you would get opening them in any reader). Using an empty string as the user password doesn't work, but it seems (section 3.5.2 of the spec) that there has to be a user password to create the hash for the admin password.
What I would like is either an explanation of how to do this, or any code that I can read (ideally Python, C, or C++, but anything readable will do) that does this so that I can understand what I'm meant to be doing.

I now have to connect the XP computer to an external network to send processing data to, so there are now two network cards on the XP computer. However, the messages sent to the external network mustn't appear on the network connecting the embedded systems together (don't want to consume the bandwidth) and the messages to the embedded systems mustn't appear on the external network.
So, the assertion I'm making is that messages sent to a defined IP address are sent out on both network cards when using the TcpClient.Connect method.
How do I specify which physical network card messages are sent via, ideally using the .Net networking API. If no such method exists in .Net, then I can always P/Invoke the Win32 API.

I need to design a control which displays a line chart. What I want to be able to do is use a designer to add multiple `Pens` which actually describe the data and presentation so that it ends up with Xaml something along these lines:
<Chart>
<Pen Name="SalesData" Color="Green" Data="..."/>
<Pen Name="CostData" Color="Red" Data="..." />
...
</chart>
My first thought is to extend `ItemsControl` for the `Chart` class. Will that get me where I want to go or should I be looking at it from a different direction such as extending `Panel`?
The major requirement is to be able to use it in a designer without adding any C# code. In order for that to even be feasible, it needs to retain its structure in the tree-view model. In other words, if I were working with this in Expression Blend or Mobiform Aurora, I would be able to select the chart from the logical tree or select any of the individual pens to edit their properties.

This is all well and good, and is a tremdous improvement over what we did in the past, but we have a problem with rerunning scripts. Obviously this isn't a problem with some scripts like altering procedures, because you can run them over and over without adversly affecting the system. Right now to add metadata and run statements like create/alter table statements we add code to check and see if the objects exists, and if they do, don't run them. Our problem is that we really only get one shot to run the script, because once the script has been run, the objects are in the environment and system won't run the script again. If something needs to change once it's been deployed, we have a difficult process of running update scripts agaist the update scripts and hoping that everything falls in the correct order and all of the PKs line up between the environments (the databases are, shall we say, "special").

He gave me a baffled look and asked when anyone would ever need to do such a thing.
Off the top of my head I didn't have a good answer for him, other than "hey, I need to do it right now". So I sat down and came up with a list of some of the things I've actually done with reflection in various languages. Unfortunately, most of my examples come from my web programming in Python, and I was hoping that the people here would have more examples. Here's the list I came up with:
1. Given a config file with lines like
x = "Hello World!"
y = 5.0
dynamically set the fields of some <code>config</code> object equal to the values in that file. (This was what I wished I could do in C++, but actually couldn't do.)
2. When sorting a list of objects, sort based on an arbitrary attribute given that attribute's name from a config file or web request.
3. When writing software that uses a network protocol, reflection lets you call methods based on string values from that protocol. For example, I wrote an IRC bot that would translate
<code>!some_command arg1 arg2</code>
into a method call <code>actions.some_command(arg1, arg2)</code> and print whatever that function returned back to the IRC channel.
4. When using Python's \_\_getattr\_\_ function (which is sort of like method_missing in Ruby/Smalltalk) I was working with a class with a whole lot of statistics, such as late_total. For every statistic, I wanted to be able to add _percent to get that statistic as a percentage of the total things I was counting (for example, stats.late_total_percent). Reflection made this very easy.
So can anyone here give any examples from their own programming experiences of times when reflection has been helpful? The next time a co-worker asks me why I'd "ever want to do something like that" I'd like to be more prepared. | reflection | null | null | null | null | null | open | Use-cases for reflection

The most adequate updating code I've found is the [.net Application Updater Component][1], which I've used for both projects. I've had to modify it recently because it uses web dav, which isn't always installed on our web servers (it still needs directory browsing, however).

I have one huge model class representing the entire building, which include collections of nodes, line elements, loads, etc. which are also custom classes.
I have already coded an undo engine which saves a deep-copy of the model class after each modification to the model. Now I started thinking if I could have coded differently. Instead of saving the deep-copies, I could perhaps save a list of each modifier action with a corresponding reverse modifier. So that I could apply the reverse modifiers to the current model to undo, or the modifiers to redo.
I can imagine how you would carry out simple commands that change object properties, etc. But how about complex commands? Like inserting new node objects to the model and adding some line objects which keep references to the new nodes.
How would one go about implementing that?
