It is quite possible. If you are using Expression Blend 4 I assume you are using WPF or Silverlight.
Video streaming is possible in both WPF and Silverlight.
See here[^] for a simple example.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

you could turn at least one machine into a web server, see e.g. this article: http://www.codeproject.com/KB/IP/CSHTTPServer.asxp[^].
And all machines could be web clients, based on either a WebBrowser Control, or the WebClient class, or the HttpRequest and HttpResponse classes.

you're welcome.
MSDN holds all the information on the classes I mentioned.
And I suggest you look around for more articles here on CodeProject, and don't forget to use Google.

i'm doing this in the .net CF 3.5.
i created a custompanel inherited by form.panel. but when trying to dock the custompanel into form at runtime , i set it's Dock property
to DockStyle.fill, but still the custompanel adds to the form with the small size(100,100). and the onresize event is fired.
any idea how to handle this
thanx in advance.

hello,
I deveopped a web application with Visual Studio 2008.My database is elaborated with Navicat 8 for Mysql.
I want to connect to my db.I have this connection string;
string ConnectionString= "Driver={Navicat 8 for MySQL};"
+ "Server=localhost:3306;" + "Database="+informations+";" + " UID=root;" + "PASSWORD=root";
when I run,it show me this error:
"informations doesn't exist in the current context",informations is my database's name.
I think that I miss to add connection from my project(Tools--->connect to database"),this doesn't show any thing to help me because i couldn't add my database.
Someone to help me is so grantful

What it is saying is the the variable "informations" does not exist in the current method as a local variable, or as a parameter,and that it does not exist at the class level either.
Have you recently moved the code from one method to another?
Or should "informations" be inside the string:
string ConnectionString= "Driver={Navicat 8 for MySQL};"
+ "Server=localhost:3306;" + "Database=informations;" + " UID=root;" + "PASSWORD=root";

Please don't attempt to bump your post. It's disrespectful.
Original post here[^].

you are getting error "information doesn't esist in the current context" because you've not created any location holder(variable) of information. as you mention "information" is your database Name then OriginalGriff pointed you a perfect answer you should put it inside as "Database =information"
for more details you can go there[^] to learn basic of creating connection

Hi,
I have a huge set of text files each being 100 kb to 1 mb. My Application reads the files (only 1 at a time) and process the string in it.
My problem is the total size of files are are very large. Is there any way, we can store the files in some format which takes lesser disk space. eg. byte array, or something...
Currently, I have zipped the files and reading the zipped file from my application. Is there any better way to do so.
Thanks,

Hi Anurag,
You should consider using an MSSQL Compact Database. This is a database that is stored in a single file.
A database will generally store very large amounts of small data extremely efficiently - as well as providing a very rapid way to query that data.
Certainly worth considering - although without more information about what the data is, it's tricky to know!
If a database isn't suitable, then you will get a size decrease and performance increase if you use a binary file format rather than a text file format.
Also note that it can be rather inefficient space-wise to have lots and lots of small files, so again finding some way to aggregate the data into a larger file that can be rapidly accessed may be good.

No.
Unless you have very particular definitions for better and process.

By "Better", by default I mean to say "Better by Performance (In terms of disk space, Time consumed and CPU utilization)".
Every time we may not explain each of our words.

so if I can do it twice as fast at the expense of twice the disk space, is it better or worse?
If you refuse to give sufficient information, don't bother asking in the first place.

Well, I don't wish to argue on this.
Apology, i could not convey my issue properly.
As already mentioned, my issue is disk space.
I can compensate on time consumed, this time, to some extent.
As someone suggested, I liked the database approach as it should take lesser space as well as it will be faster.
Thanks Anyways.

When disk space is your primary concern:
- I don't see how a database would be more compact than plain text files;
- compression is what you want, ZIP is very good at compressing text (however it takes lots of cycles to decompress).
If you find anything significantly better than ZIP I will be very interested!

Ok, for the time being I will keep the zip aproach only.
I will let you know, in case, i will get better approach.
Thanks for all your help Luc.

I have to agree with Luc.
ZIP is probably the smallest you will practically get it (or RAR - I won't argue).
A database will quite likely increase the space taken up, as it stores all sorts of extra information over and above your text (table definitions, row ids, etc.).
However, a database may improve the raw disk space usage compared to a lot of separate files, depending on your HDD format. In some formats, a file must occupy complete clusters, so a lot of files mean a lot of partially empty clusters. This is not the case with database or zip.
MySQL does support a COMPRESS function that shrinks a text string, I don't think MsSql does (I could be wrong). However, it required a ZIP library to be loaded so it won't save you anything over using ZIP directly!

zipping seems to be a good idea.
without knowing anything about the content/structure of your textfiles, its not possible to say more.
I cannot remember: What did I before google?

Hi,
Thanks for your response.
Each file is a list of string which needs to be parsed by the application.
Those string will essentially contain ASCII chars only. UTF-8 only.
|

strings -> zip -> optimal.
if you provide sample data, maybe we can found something else.

As mentioned before, if you can extract the data to a database, that would be the best, most flexible solution.
If the string data is predominately numeric you could convert the numeric data to a numeric datatype and then store the file as a binary file. A binary representation of a number is typically a chunk smaller than the string representation of the same number.
