you never now, maybe he is the teacher. He didnt put a specific question so maybe that post was an assignment brief he wanted proof reading.

I completely agree, it seems many people attemp programming as a route for a better life, or better job prospects. Personally i choose the route through sheer enjoyment of the subject, thats why you wil never see my posting for others to do my work.

Solving the problems is half the fun - if not 3/4... or 4/5...

for(int i = 5; i > 0; i++)
    thisPost.Write(" or " + i + "/" + (i+1) + "...");

My opinion is... If someone has already posted an answer, dont post the SAME answer

That is not correct. There is not a single solution with that length. You could just as well use the solution that starts 4->6->9->12...

sorry you will need the 'gradient histogram' forum

GHForum[^]

sorry - this link a bit dodgey you wil have to keep following it a few times before the forum comes up, something to do with 'internal codeproject hyperlink looping using external forum sources', ICHLUEFS for short, it a safegaurd on this site to prevent random advertising posts

Hi,

Histogram represents the tonal distribution in an image , for this you need to write Image Processing Algorithms , which are not very simple to explain Frown | :(

.

But what i can suggest you is start looking at some of the information available on the net and come up with specific questions.

Also there are many open source Image Processing Libary , which you can use , AForge.Imaging (read the license properly before use )
you may download it from

http://code.google.com/p/aforge/[^]

Also the following link has an example of drawing histogram (with other stuff) , using the AForge.Imaging Libary

http://www.codeproject.com/KB/GDI-plus/Image_Processing_Lab.aspx[^]

Also this are wikki links about histograms

http://en.wikipedia.org/wiki/Image_histogram[^]

Let me know if the info was helpful , also feel free to ask for any info

Listing drives from a server

Hi,
I am new to C#

For writing C# code for the above should i install SQL....
Please help with this

Yes, you are new, and very lost. I don't believe you can iterate over the drives on a server. SQL Server certainly has nothing to do with this. Directory.GetAllDirectories and Directory.GetAllFiles is what you need, once you have a drive.

Overall, what you need is to read a basic book on C#

Hi,

you have to write a server-application that provides the information about drives and files. For example a WebService could suit your needs perfectly.

And you don't need SQL for this. SQL is a language used to query relational databases.

Why would you need SQL? are you storing data?

Plus have you tried looking, there is loads of stuff out there. Try looking into 'C# WMI' or 'C# list server drives' or something.

You put a question like this your more than likely to only get 'links' as replies, which you could get much faster if you searched yourself

BinaryReader and BinaryWriter are probably the classes you are looking for.

What sort of data is it you are writing? Are you trying to write it in a specific format? Is it binary serialisation you are after or more just straight streaming of data?

Rob Philpott.

What does the binary data represent? An image, text or sth. else?

Because I don't know what you try to achieve, I would say you have to use a BinaryWriter/BinaryReader.

Well, why don't use a StreamWriter for this... it's there for text and numbers.

Anyway here is the link to the MSDN with a nice piece of sample code using BinaryReader and BinaryWriter:

BinaryReader/BinaryWriter as has already been suggested.

If you are trying to save your own internal objects in a proprietary format also take a look at BinarySerializer
