That's the problem. You should not have access to other people's passwords, end of story.

If you did, you'd be asking for explanation on the salt.

Really? I'd be willing to bet every single one of those "suggestions" was written by a security moron. The problem with encrypting a password is that it can be unencrypted and therefor broken. A salted and hashed password cannot be reversed to get the original string, making it FAR more secure.

just to answer you question - ExecuteNonQuery() return the number of rows effected which is zero ! Try using ExecuteScalar() !

I am reading a file and extracting a string
AB01AN728930JJ7YI8
VD036583AH84000002
In this string we have differenct section like AB,01,AN728930,JJ7YI8 in one line second line has VD,036583,AH84,000002
now there will be predefined line and predefined sections in string and each section will have some common validation like length, data type etc.
What is the best way of processing the validation on each character set

Try regex, The 30 Minute Regex Tutorial[^]
This tutorial will take you more than 30 minutes to read and understand if you are the first timer.
Formulate the regex patterns according to your respective validation rules.

how to read character from a particular position to a particular position in REGEX
|
|
|
|
|
You don't. RegEx uses patterns to match against, not positions.
If you know the specific positions, then you can just use the Substring method of the String class to get it. Start at this position and return x number of characters.
|
|
|
|
|
How many variants are there on the split up of the string ? - you show two, ie,
If String Starts With 'AB', then Format is AB, XX, YYYYYYYY, ZZZZZZ
If String Starts With 'VD', then Format is VD, XXXXXX, YYYY, ZZZZZZ
Before you go reaching for Regex, Id almost be suggesting that you look at Recursive Descent Parsing, or a parser based on a Grammar, using ANTLR perhaps - this would allow you to have rules, validation built in

how to split all hindi unicode characters.
StringBuilder sb = new StringBuilder();
string[] data = textBox1.Text.Split(new char[] { ' ' });
foreach (string s in data)
{
Regex ex = new Regex(@"(\w|\d)",RegexOptions.CultureInvariant);
MatchCollection col = ex.Matches(s);
foreach (Match mat in col)
{
// string d = Worddictonary[mat.ToString()];
sb.Append(mat.ToString());
sb.Append("\n");
}
}
For the input मोहनदास I am getting the output as
म ह न द स
The desired output is
म ो ह न द ा स
Can anyone please help to split Unicode Hindi string. Its very urgent.
Thanks in advance..

Unfortunately the 'normal' rules for string splitting often do not work for non-Latin languages. You will have to write your own parser that recognises the different characters.

string[position] returns the character at the given position. I just tested it with your example text, and it worked correctly:
private void button1_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < textBox1.Text.Length; i++)
{
char indianChar = textBox1.Text[i];
sb.Append(indianChar);
sb.Append(" ");
}
MessageBox.Show(sb.ToString());
}

I am working on a touch surface, I need to create two desktops on a single surface running on a single Operating System (Windows 7), so that two users can simultaneously use them. Please guide me where to start and provide related links.

Google and MSDN would be the logical choice.

Only a single desktop can be shown simultaneous. That's a technical limitation in Windows.
You could show two remote desktops on a single screen.

Do I understand that correctly:
- there is only one computer.
- that computer runs Windows 7
- there are two monitors attached to this computer.
- there are two users, each of them uses one of the monitors
The limitation of Windows 7 is that only one user can have an interactive session at a time. Hence, from the point of view of Windows, there is only one user in your scenario (i.e. both of your users work in the same session, with the same Windows account).
All user interface elements run in the UI thread of the program instance - a real multitasking is not possible with the user interface. You could circumvent that by starting two instances of your program. Each instance would communicate with a "server" (a Windows Service) which provides the back-end for your UI applications and which may run on the same computer.

Why do you think I am going to go a a random site and download random code, the size and nature of which I do not know? Why do you think I want to search your code to find the code you write about? Do you think that is a good use of my time?
Edit your question, remove the links, and paste the relevant code fragments - just the bits with the problem and a few lines around for context - to make it easier for us to identify your problem.

I am looking for a plugin (dll or wotever) that will enable me to view an Analogue voltage on a grid type view. I also want to be able to follow this Analogue voltage and therefore the current value will be displayed in the middle of the grid.
It would also be nice to have scroll bars so I can stop the sampling and look back on previous values.
I could write one from scratch but it will obviously take time.
A free plugin that has these features would be ideal if anyone has any suggestions.
Thanks.

The Chart control that ships with Visual Studio is more than capable of doing this.

Tools: Visual Studio 2010 Ultimate, Language C#, Database MySql
Hi,
I am searching this a while, but to date didn't find any suitable solution.
I've a form with bound DataGridView with 5 columns, ProductID, ProductName, Qty, Price and Amount. After normal data entry user can click button to save data to Mysql database, no problem there.
At present user is manually enter ProductID after which an Sql command is executed to fetch ProductName and sets it to DataGridView ProductName Column. I need a way to show a ListView below ProductID column when it got focus, so that user can select product (ProductID and ProductName) from ListView and set it to DataGridView's Row which user is currently using.
Is it possible to show listview below ProductID cell when user click or when got focus?
Thanks
Ahmed
