Hi all, i use the following code to encrypt a string using MD5:
using System.Security.Cryptography;
public static string EncodePassword(string originalPassword)
{
Byte[] originalBytes;
Byte[] encodedBytes;
MD5 md5;
// Conver the original password to bytes; then create the hash
md5 = new MD5CryptoServiceProvider();
originalBytes = ASCIIEncoding.Default.GetBytes(originalPassword);
encodedBytes = md5.ComputeHash(originalBytes);
// Bytes to string
return System.Text.RegularExpressions.Regex.Replace(BitConverter.ToString(encodedBytes), "-", "").ToLower();
}
But i don't know how to decrypt it using MD5 ????????
Do anyone help me ?????????
Regards...

MD5 is one way encryption, you cannot decrypt it, you can only compare the encrypted value against a dictionary to see if it matches are predefined list of encrypted strings. See this[^] wikipedia article.

In addition to Elliots response, you should not use MD5 for new applications - it is considered "broken" and should not be used for any new development. Use SHA512 instead, until the SHA 1024 specification comes out in 2012.
All those who believe in psycho kinesis, raise my hand.

You don't. MD5 is a one-way hash. You cannot get the original string back from the encrypted hash.

Hi All
I need to develop a C# client able to save a web page given a URL.
The problem I am is that the web pages i.e. the content are rendered by some javascript.
Can you advise me about an easy way to do that?
Thanks

You don't say in what format you want to 'save' the page.
You may be able to render the page using a System.Windows.Forms.WebBrowser control and use that.

My Page renders a simple HTML table generated automatically by some javascript.
I would like to save the rendered page in HTML format so that I can parse it
or reload it later.

Well
I have just found what I need for my specific purposes; I hope that it fits also yours.
Please have a look at this project The most complete C# Webbrowser wrapper control[^]
Digging and trying I found that this project provides DOM information and is exactly what I need.
I found that you need an active x for accomplish this handling the IHTMLDocument2 class.
PLease look also here column_1[^] and here column_2[^]
|

Probably I found what I need to do.
I have to download something called DOM information. For my purpose it would be enough.
Do you know how to do that in C# after a web page was loaded?

Hi to all.
How can I easily convert HTML to well formed XML? Does anyone has an idea how I can do that? Thank you for your time.
|
|

|

First, since HTML does not conform to XML standards, there is no direct conversion. You'll have to define what you mean by the conversion, what you want converted, and why you think you need this. Perhaps there is another method that will work better than the one your trying.

Are you sure? Ifyou are looking at the data in your application you need to refresh your datasource to see changes. Look directly in the database to see if it has been updated.

Did you use commit in your sql?

It's a sql command that makes db changes (to tables) permanent.
Learn how to use google.

How do you insert, delete and update?
|
|
|
|
|
with procedure and I examined these procedure with other database and these procedure work correctly
|
|
|
|
|
As you added this database file to your project did you maybe select "always copy" on the "copy to output directory" property (I don't know the exact phrase in the english studio for this)?
Because this overrides the "modified" database file with the old one (this will be done every time you build your project).
If so, try to use the setting "only if newer".
