My question is, do I need to synchronize access to this multi-byte value anyway? Or, put another way, can part of the write be complete and get interrupted, and then the read happen.
For example, think of
value = ox0000FFFF
increment value to 0x00010000
Is there a time where the value looks like 0x0001FFFF that I should be worried about? Certainly the larger the type, the more possible something like this is

I know the .Net framework will not allow a web.config file to be served, however I still think its bad practice to leave this sort of information in plain text.
Everything I have read so far requires me to use a command line switch or to store values in the registry of the server. I have access to neither of these as the host is online and I have only FTP and Control Panel (helm) access.

The problem I'm having is trying to work with the other teams in the company who are authoring the services I'm consuming. I found I needed to capture the exact SOAP messages that I'm sending and receiving. I did this by creating a new attribute that extends SoapExtensionAttribute. I then just add that attribute to the service method in the generated Reference.cs file. This works, but is painful for two reasons. First, it's a generated file so anything I do in there can be overwritten. Second, I have to remember to remove the attribute before checking in the file.

The tool itself is large, complicated, and refactoring or rewriting would take more resources than we are able to devote to it for the forseeable future, so my hands are tied when it comes to large modifications. I must use a .NET language.
The files are XML serialized versions of four classes that are used by the tool (let's call them A, B, C, and D). The classes form a tree structure when all is well. Our editor works by loading a set of files, deserializing them, working out the relationships between them, and keeping track of any bad states it can find. The idea is for us to move away from hand-editing these files, which introduces tons of errors.
For a particular type of error, I'd like to maintain a collection of all files that have the problem. All four classes can have the problem, and I'd like to reduce duplication of code as much as possible. An important requirement is the user needs to be able to get the items in sets; for example, they need to get all A objects with an error, and telling them to iterate over the whole collection and pick out what they want is unacceptable compared to a <code>GetAs()</code> method. So, my first thought was to make a generic item that related the deserialized object and some metadata to indicate the error:
public class ErrorItem<T>
{
public T Item { get; set; }
public Metadata Metadata { get; set; }
}
Then, I'd have a collection class that could hold all of the error items, with helper methods to extract the items of a specific class when the user needs them. This is where the trouble starts.
None of the classes inherit from a common ancestor (other than <code>Object</code>). This was probably a mistake of the initial design, but I've spent a few days thinking about it and the classes really don't have much in common other than a GUID property that uniquely identifies each item so I can see why the original designer did not relate them through inheritance. This means that the unified error collection would need to store <code>ErrorItem<Object></code> objects, since I don't have a base class or interface to restrict what comes in. However, this makes the idea of this unified collection a little sketchy to me:
Public Class ErrorCollection
{
public ErrorItem<Object> AllItems { get; set; }
}
However, this has consequences on the public interface. What I really want is to return the appropriate <code>ErrorItem</code> generic type like this:
public ErrorItem<A>[] GetA()
This is impossible because I can only store <code>ErrorItem<Object></code>! I've gone over some workarounds in my head; mostly they include creating a new <code>ErrorItem</code> of the appropriate type on-the-fly, but it just feels kind of ugly. Another thought has been using a <code>Dictionary</code> to keep items organized by type, but it still doesn't seem right.
Is there some kind of pattern that might help me here? I know the easiest way to solve this is to add a base class that A, B, C, and D derive from, but I'm trying to have as small an impact on the original tool as possible. Is the cost of any workaround great enough that I should push to change the initial tool? | .net | generics | null | null | null | null | open | How should I handle a situation where I need to store several unrelated types but provide specific types on demand?

I don't even know if this is possible right now, but I think flash has access to local webcams running through the browser.
Do you have any suggestions or resources to get me started on this? I'm primarily a java developer so If I could do it in an applet that would be great, but It may be easier to accomplish this using flash or some other technology.
This would mean streaming the video back to the webserver and storing it there.
Uploading a file is easy enough, but I'd rather the user not have to deal with that if it's possible.
Just to be clear. I'm not talking about uploading a video. I'm talking about allowing the user to click "record" in a web application and having the video streamed to the server and stored when the user clicks "stop".

In his [examples][2] his user groups are set up as a cascading tree, with the most general user type being at the top of the tree, and its children branching off for each more restricted access type. Elsewhere I've usually seen each user type as a child of the same generic user type.

I'm looking for any tools that can give you code churn metrics (graphs and charts would be even better) for a Subversion repository.
One tool I know of is [statsvn][1] - a Java tool that creates some HTML reports and some code churn metrics.
I wanted to know if there are any others that are maybe open source, extensible, etc.

My web application (C#, .Net 3.0, etc) has Themes, CSS sheets and, of course, inline style definitions. Now that's alot of chefs adding stuff to the soup.

I am sure that all these styles are applied in a hierarchical method (although I am not sure of that order). The issue is that each style is applied as a "transparent" layer which just masks what it is applying. This is, I feel, a good idea as you can specifiy styles for the whole and then one-off them as needed. Unfortunately I can't tell from which layer the style actually came from.
I could solve this issue by explicitly expressing the style at all layers but that gets bulky and hard to manage and the page(s) works 80% of the time.

* it's a regular GUI app when invoked with no command line arguments
* specifying the optional "--help" command line argument causes the app to write usage text to stdout then terminate
* it must be a single executable. No cheating by making a console app exec a 2nd executable.
* assume the main application code is written in C/C++
* bonus points if no GUI window is created when "--help" is specified. (i.e., no flicker from a short-lived window)
In my experience the standard visual studio template for console app has no GUI capability, and the normal win32 template does not send its stdout to the parent cmd shell.

Using this code in the bowels of the codebehind:
foreach (RepeaterItem item in rptrFollowupSummary.Items)
{
string val = ((DataBoundLiteralControl)item.Controls[0]).Text;

}
I produce this:

What I need is the data from Field1 and Field4
I can't seem to get at the data the way I would in say a DataList or a GridView, and I can't seem to come up with anything else on Google or quickly leverage this one to do what I want. The only way I can see to get at the data is going to be using a regex to go and get it (Because a man takes what he wants. He takes it all. And I'm a man, aren't I? Aren't I?).
Am I on the right track (not looking for the specific regex to do this; forging that might be a followup question ;) ), or am I missing something? | 0 |

I have a VB6 application I've "inherited" that generates a PDF for the user to review using unsupported Acrobat Reader OCX integration. The program generates an FDF file with the data, then renders the merged result when the FDF is merged with a PDF. It only works correctly with Acrobat Reader 4 :-(. Installing a newer version of Acrobat Reader breaks this application, making the users very unhappy.
I want to re-architect this app so that it will send the data to be merged to a PDF output generation server. This server will merge the data passed to it onto the form, generate a PDF image of this, and store it, so that any user wishing to view the final result can then simply get the PDF (it is generated just once). If the underlying data is changed, the PDF will be deleted and regenerated next time it is requested. The client program can then have any version of Acrobat Reader they wish, as it will be used exclusively for displaying PDF files (as it was intended). The server will most likely be written in .NET (C#) with Visual Studio 2005, probably as a Web Service...
**Question**:
How would others recommend I go about this? Should I use Adobe's Acrobat 9 at the server to do this, puting the data into FDF or Adobe's XML format, and letting Acrobat do the merge? Are there great competitors in the "merge data onto form and output a PDF" space? How do others do this? It has to be API based, no GUI at the server, of course...
While some output is generated via FDF/PDF, another part of the application actually sends lines, graphics, and text to the printer (or a form for preview purposes) one page at a time, giving the proper x/y coordinates, font, size, etc. for each, knowing when it is at the end of a page, etc. This code is currently in the program that displays this for the user to review, and it is also in the program that prints the final form to the printer. For consistency between reviewer and printer, I'd like to move this output generation logic to a server as well, either using a good PDF generation API tool or use the code as is and generate a PDF with a PDF printer... and saving this PDF for display by the clients.
Googling "Form software" or "fill form software" or similar searches returns sooooooooo much unrelated material, mostly related to UI for users to fill in forms, I just don't know how to properly narrow down my search. This site seems the perfect place to ask such a question, as other programmers must also need to generate similar outputs, and have tried out some great tools. | .net | forms | pdf-generation | null | null | null | open | How to best merge information, at a server, into a "form", a PDF being generated as the final output

I want to tokenize it, however I can't just split on the spaces. I've come up with somewhat ugly parser that works, but I'm wondering if anyone has a more elegant design.
This is in C# btw.

I have an element that I want to append a div to. Then I have another element that I want to clone and shove into that intermediate div. Here's what I was hoping to do:
$("#somediv > ul").after("<div id='xxx'></div>").append($("#someotherdiv").clone());
This seems to be close, but not quite there. The problem with this is that the "append" seems to be operating on the original "#somediv > ul" selector. This sort of makes sense, but it's not what I wanted. How can I most efficiently select that intermediate div that I added with the "after" and put my "#someotherdiv" into it?

It is possible to configure the JVM so it generates UTF-8, using `-Dfile.encoding=UTF-8` as arguments to the JVM. It works fine, but the output on a Windows console is garbled.
Then, we can set the code page of the console to 65001 (`chcp 65001`), but in this case, the `.bat` files do not work. This means that when we try to launch our application through our script (named start.bat), absolutely nothing happens. The command simple returns:
C:\Application> chcp 65001
Activated code page: 65001
C:\Application> start.bat
C:\Application>
But without `chcp 65001`, there is no problem, and the application can be launched.
Any hints about that?
Thanks in advance.

if (!string.IsNullOrEmpty(ddlFileName.SelectedItem.Text))
results = results.Where(x => x.FileName.Contains(ddlFileName.SelectedValue));
if (chkFileName.Checked)

if (chkIPAddress.Checked)

`results` is an `IQueryable<MyObject>`.
The idea is that for each of these innumerable dropdowns and checkboxes, if the dropdown has something selected, the user wants to match that item. If the checkbox is checked, the user wants specifically those records where that field is null or an empty string. (The UI doesn't let both be selected at the same time.) This all adds to the LINQ Expression which gets executed at the end, after we've added all the conditions.
It *seems* like there ought to be some way to pull out an `Expression<Func<MyObject, bool>>` or two so that I can put the repeated parts in a method and just pass in what changes. I've done this in other places, but this set of code has me stymied. (Also, I'd like to avoid "Dynamic LINQ", because I want to keep things type-safe if possible.)
