hello!
hope you all are doing fine! i was just wondering if there is any way to get the process id of an application, from within an application! like i want to know what PID is assigned to the application when it is executed! if the application is executed multiple times, each instance displays its own PID! any solution for that??
Thanx in advance! !

System.Diagnostics.Process.GetCurrentProcess().Id will return to you the PID of your application instance

Hi,
I have 2 forms. In the first form I declare a array :
public string[] Name_Menues = new string[10];
Name_Menues[1] = "Mareya" ;
Name_Menues[2] = "Mareya1";
Name_Menues[3] = "Mareya2";
Now I wana to show the value of this array in form2
messagebox.show(Name_Menues[1]);
But when I run it there is some problem and i think i use a wrong code.
please say what should I do??????

What exactly is "some problem"? It's hard to say what's wrong without any kind of error message.
If the array was not available in that scope, the code would not even compile, so you would not be able to run it at all. What are you doing to make the array available in the second form? Are you passing the array along in any way, or are you just creating another array with the same name, hoping that it would become the same array?

I have notice that the default members and properties in resource.resx file is internal in VS2005 by microsoft and there isn't any property that allows a resource file to be declared as public uncless declared explicitly. Is there anyway to set/change the behaviour of the resource file from internal to public class Resource1 {} and all it's members to be public as well whenever they are added. I couldn't figure it out can somebody help me in it.
Thanks

Hi there!
I want to save an encrypted password in a database in order to authenticate the users of my application (on C# 2.0).
So, I encrypted the password provided by the user, as following:
UnicodeEncoding unicodeEncoding = new UnicodeEncoding();<br />
byte[] passwordArray = unicodeEncoding.GetBytes(password);<br />
SHA1Managed sha1Managed = new SHA1Managed();<br />
byte[] encryptedPassword = sha1Managed.ComputeHash(passwordArray);
Then, I saved the password in 'varbinary(160)' field in a table of database (SQL Server 2005):
DataSet.Users.AddUsersRow(userName, encryptedPassword);<br />
UsersTableAdapter userTableAdapter = new UsersTableAdapter();<br />
userTableAdapter.Update(DataSet.Users);
How can I recover this encrypted password in order to compare it with a new encrypted password provided by the user?
This code:
byte[] passwordArray = row["Password"];
doesn't compile because "it can't convert object to byte[]".
Thank you, in advance.

Try casting it first:
byte[] passwordArray = (byte[])row["Password"];

Thank you very, very much!

In VS 2003 I used SBCollectionGenerator to auto-generate strongly-typed collections from .xml files. In VS 2005 the base classes and some interfaces are no longer accessible. Is there a work around or a new tool for VS 2005?
Thanks for help

hi how can i disable alt+f4 key please give me some clue if possible please send some sample
code in c#.

You might be able to with a system wide keyboard hook. Also, doesn't that close a program ? The onclosing event might be useful, you could write code to refuse to close, unless some condition is met ( such as, ALT is not held down )

Yeah, that's what I'd suggest.
private bool closeok = false ;
private void button1_Click ( object sender , System.EventArgs e )
{
this.closeok = true ;
this.Close() ;
}
private void Form1_FormClosing ( object sender , System.Windows.Forms.FormClosingEventArgs e )
{
e.Cancel = !closeok ;
}
The form will only close due to a click of button1.
(In addition, if you haven't already, set the form's ControlBox = false;)

Does anybody know of any way to find out which application/process has locked a file?
As an example, you have a file called widgets.txt and when you try and delete it you get a message along the lines of "Cannot delete widgets.txt, there has been a sharing violation, the source or destination file may be in use". The problem is this message doesnt tell you what it actually holding a handle on the file.
I am currently working under the assumption that there is something in the Win API that I can call to get this information, however I am currently at a loss to what it is.

Well, assuming the first row is headers, I'd create a struct that defines the collection of data in each row, so looks like two strings, and three floats, and then make an array of that type.
I'd use the List class, rather than an array.
