I have a webbrowser control in my desktop application and its background color and foreground colors are needed to be changed at runtime. How to achieve it. please send some sample code to do this.
Thanks

Look, the webbrowser control(or even a web browser) does not have a background color on its own.
It's basic purpose is to render the page it shows.

What you can do, is to update the displayed html page using Javascript
So you must make some changes and decision on how you display (generate) your html source.

Ok I pulled this from www.aspnettutorials.com I want to know if I can take this and make it a strong encryption method. I wanna be able basically to create a page that allows a text box then it encrypt it and saves it to the server. Then later another user can connect to the same page unencrypted and view what was written. Does that make any sense? I all so want to make the original page that the clear text is being sent to, encrypted as not to have it clear text method.I would post the whole script but it is very long.

Thanks!

Hey Jackeli
"Strong encryption" methods are not something we just sit and come up with, There are cryptographers and cryptanalysts that this is what they're doing.
They come up with "Strong Encrpytions" (and try to break them...).
So if you want to use a "strong encryption", you just need to learn how to use one.
I'll try to explain a little bit about it, but before you get down to the code you need to plan a little bit how you're going to do what you want, that is, encrypt the given text in such a way only certain people will be able to see it.
I think what you are looking for is called "Symmetric encryption" (There are "ASymmetric encryptions" as well), so I'll explain a little bit about it (not technical stuff, but the idea, so you will understand better what you're going to do).
- "Symmetric encryption" means that if you encrypt text with a certain KEY, we need that exact KEY to decrypt. What is a KEY? it can be a password, passphrase, a file. In other words, a KEY is an array of bytes (byte[]).
using this KEY we encrypt and decrypt the text.
So if we'll look at the page you want to write, it means, that I can write a certain sentence, like: "This is my hidden message", and encrypt is using the password "Secret Password!".
Now, if I want you to read my message, you need to know the password. So I will need to tell you the password somehow, only then you can go to the website, and use the password "Secret Password!" and reveal the encrypted text: "This is my hidden message".
This is the tip of the ice burg.
Today's standard symmetric encryption is called "AES", and C# libraries are giving you a method that is doing just what you want (There are many other methods, but I think you should focus one).
Look for it a little bit in codeproject and you will find plenty of examples on how to do it, and other stuff I didn't quite got into in this example (the more technical stuff).
I hope it helped!
Good Luck!

If you read that article it points out quite clearly that it is not at all a good, secure method of encryption. It is a very simple substitution cypher which would be cracked in seconds by anyone with enough reason to do so and the right software.
If you want to learn more about encryption the .net framework has a number of classes you can utilise. I suggest a good google search[^] will provide you with tons of information.

Thanks to MatzeS (in his question 4 hours ago) I managed to put a form on a tabpage.
The form seems to operate allright, but in the datagridview on the form I miss the scrollbars
I use C# Express 2008
How can I make sure the scrollbars are showing ?

Answering my own question (after extensive experimenting):
I had the DataGridView anchored on four sides, when I changed that to dock on top the Scrollbars appearead again.
I would rather have anchoring, but I can live with this solution.

Dear Sir and Madam,
"WD-WCANKF003333" is my harddisk id and
"4&32BEFC79&0&0.0.0" is my harddisk id from ManagementClass.
Do you understand relation between them and how to convert them?
Thank you very much.

The first thing you listed is the Model.
The second thing you listed is the PnpDeviceID.
They're both retrieved from the same management class. You may have more than one drive with the same Model designation, but I think the PnpDeviceID might be unique between drives of the same model.
So, now that you know this, tell us what you're trying to do.

I have one drive.
The Model is WDC "WD2500JS-22NCB1"
The unique ID is "WD-WCANKF003333"
I found in some message board tell me that "4&32BEFC79&0&0.0.0" is unique ID.
"4&32BEFC79&0&0.0.0" may be hex of a string.
I try to convert "4&32BEFC79&0&0.0.0" to "WD-WCANKF003333"
Sorry for bad English.

Hi Guys. Do any of you know if it is possible to pull an image into an app and read data of it? I have aproximately 280 000 .TIF files. I want to or would like to know if I can read data from the image. The image is a scanned image of a word document. I need to be able to read/search the image for certain words and do something with it.
Does anybody know if this is possible at all?

That's called OCR, you need to buy a library for that.

Thanks Christian. Woud it let me read data of an already scanned image? I thought it only possible to read the characters while it is scanned.

Well, it depends on the Reader. What kinda data does your image contain?

OCR is an operation that works on a bitmap by examining it for shapes it thinks are text. It can only work post scan, even if some OCR that runs with a scanner appears to work as it scans.

You might try using the Office 2007 imaging services, although I have no clue on how the APIs work or where you can get docs.
