My thoughts on moving from Windows to Linux Mint
bootneck02Any way as I have said I had dabbled once or twice with Linux Distro's and never really tried to understand them but was so fed up with Microcrap I tried several one was Zorin the other was Roblinux both full to the brim with apps but two many apps because they supposedly easy to migrate from Microsoft I found them full of features but really did not sit right with me and then I tried against my better judgement Linux Mint. I found it was easy to use and there is a button to download World Community Grid, all you have to do is forget all Microsoft put all the things out of your mind that you know about that system and it is a new learning experience and as I am a silver surfer that could be a difficult thing but straingly I have found it easy to get my head around and enjoying the experience, so if you are questioning the morality of Microsoft monitoring your privacy have a look at Linux Mint or any other Linux distro you could be surprised and if you need help there many people on this site who will go out of their way to help you.

Mint does simplify the knowledge requirements for the Linux
keyboard commands. Among non-programmers, the competition includes
Apple tablets and macs which arguably easier to use than Mint.

I am able to fetch all the processes which are running in Windows
task Manager. Now I want to end a particular process from those
processes. Is it possible in Java, or do i need to write some native
code??

Type Conversion
Type conversion is necessary for c#. Here is an example.

So I have a button that calls a Class. The Method reads a file, stores the results in a Dictionary (tried Hashtable first and got the same error). I return the Dictionary variable. Then I try to loop through the results so I can save and reuse them later. For testing I am just trying to put the results into a listbox.
I'm getting the error: CS0030 Cannot convert type 'char' to 'System.Collections.Generic.KeyValuePair<string, string>'

The solution requires returning Dictionary <string, string> not a string from getCharacter.getCharacter function.

C# Email Utility
Introduction
Creating the Workspace
Code
. Sender
. Copy List
. Priority
. Body Encoding
. Subject
. Message Body
. SMTP Server
App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>

<add key="Email.Sender" value="Bob.Jones@xyz.com " />
<add key="Email.Copy" value="mycclist@xyz.com" />
<add key="Email.Priority" value="MailPriority.Normal "/>
<add key="Email.Encoding" value="Encoding.ASCII"/>
<add key="Email.Subject" value=".NET Email Utility Sample"/>
<add key="Email.Message" value="This email provides an example of sending a .NET email using C#."/>
<add key="Email.Smtp" value="mailhost.xyz.com" />
</appSettings>
</configuration>
The Email Handler
using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
using System.IO;
namespace EmailApp
{
public sealed class EmailHandler
{
private static char[] charSeparators = new char[] { };
private static String[] result;
public static void SendMailMessage(string smtpHost, MailAddress from, string to, string subject, string message)
{
try
{
MailMessage mailMsg = new MailMessage();
result = to.Split(charSeparators, StringSplitOptions.RemoveEmptyEntries);
for (int count = 0; count < result.Length; count++)
{ mailMsg.To.Add(new MailAddress(result[count])); }
mailMsg.From = from;
mailMsg.Subject = subject;
mailMsg.Body = message;
mailMsg.Priority = AppHandler.EmailPriority;
mailMsg.BodyEncoding = AppHandler.EmailEncoding;
SmtpClient smtpClient = new SmtpClient(smtpHost);
smtpClient.Send(mailMsg);
}
catch (Exception exc)
{}
}}}
The AppHandler class makes the application parameters accessible as static variables in the EmailHandler class.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
namespace EmailApp
{
public static class AppHandler
{
private static MailAddress emailRecipient;
private static String emailSender;
private static String emailCopy;
private static String emailPriority;
private static String emailEncoding;
private static String emailSubject;
private static String emailMessage;
private static String emailSmtp;
public static MailAddress EmailRecipient
{get { return emailRecipient; }
set { emailRecipient = value; }}
public static String EmailSender
{get { return emailSender; }
set { emailSender = value; }}
public static String EmailCopy
{get { return emailCopy; }
set { emailCopy = value; }}
public static String EmailPriority
{get { return emailPriority; }
set { emailPriority = value; }}
public static String EmailEncoding
{get { return emailEncoding; }
set { emailEncoding = value; }}
public static String EmailSubject
{get { return emailSubject; }
set { emailSubject = value; }}
public static String EmailMessage
{get { return emailMessage; }
set { emailMessage = value; }}
}}
The EmailHandler usage involves setting the configuration parameters and calling one line of code.
AppHandler.EmailRecipient = new MailAddress(System.Configuration.ConfigurationManager.AppSettings["Email.Recipient"]);
AppHandler.EmailSender = System.Configuration.ConfigurationManager.AppSettings["Email.Sender"];
AppHandler.EmailCopy = System.Configuration.ConfigurationManager.AppSettings["Email.Copy"];
AppHandler.EmailPriority = System.Configuration.ConfigurationManager.AppSettings["Email.Priority"];
AppHandler.EmailEncoding = System.Configuration.ConfigurationManager.AppSettings["Email.Encoding"];
AppHandler.EmailSubject = System.Configuration.ConfigurationManager.AppSettings["Email.Subject"];
AppHandler.EmailMessage = System.Configuration.ConfigurationManager.AppSettings["Email.Message"];
AppHandler.EmailSmtp = System.Configuration.ConfigurationManager.AppSettings["Email.Smtp"];
EmailHandler.SendEmail(AppHandler.EmailSmtp, AppHandler.EmailSender, AppHandler.EmailRecipient, AppHandler.EmailSubject, AppHandler.EmailMessage);
This useful C# .NET email utility configureseasily identifying the receiver, sender, message content and mailserver requiring minimal time for implementation.
Creating the Workspace
To start the Email Utility project, open aMicrosoft Visual Studio 2005, .NET Framework Version 2.0 developmentenvironment and create a Console Application. Add two C# classes, onecalled EmailHandler.cs and another called AppHandler.cs and anApplication Configuration File called the default, App.config.
Code
As with any Microsoft C# project, theapplication consists of the configuration properties and theapplication. By default the App.config file is XML with a primaryelement named .configuration.. To the default .configuration. element,set the properties required for email configuration:
. Recipient. Sender
. Copy List
. Priority
. Body Encoding
. Subject
. Message Body
. SMTP Server
App.config
<configuration>
<appSettings>
<add key="Email.Recipient" value="John.Smith@abc.com, Joe.Wilson@abc.com" />
<add key="Email.Sender" value="Bob.Jones@xyz.com " />
<add key="Email.Copy" value="mycclist@xyz.com" />
<add key="Email.Priority" value="MailPriority.Normal "/>
<add key="Email.Encoding" value="Encoding.ASCII"/>
<add key="Email.Subject" value=".NET Email Utility Sample"/>
<add key="Email.Message" value="This email provides an example of sending a .NET email using C#."/>
<add key="Email.Smtp" value="mailhost.xyz.com" />
</appSettings>
</configuration>
The Email Handler
The Email Handler provides a simple method forsending the email using the parameters defined in the applicationconfiguration file.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
using System.IO;
namespace EmailApp
{
public sealed class EmailHandler
{
private static char[] charSeparators = new char[] { };
private static String[] result;
public static void SendMailMessage(string smtpHost, MailAddress from, string to, string subject, string message)
{
try
{
MailMessage mailMsg = new MailMessage();
result = to.Split(charSeparators, StringSplitOptions.RemoveEmptyEntries);
for (int count = 0; count < result.Length; count++)
{ mailMsg.To.Add(new MailAddress(result[count])); }
mailMsg.From = from;
mailMsg.Subject = subject;
mailMsg.Body = message;
mailMsg.Priority = AppHandler.EmailPriority;
mailMsg.BodyEncoding = AppHandler.EmailEncoding;
SmtpClient smtpClient = new SmtpClient(smtpHost);
smtpClient.Send(mailMsg);
}
catch (Exception exc)
{}
}}}
The AppHandler class makes the application parameters accessible as static variables in the EmailHandler class.

Variable or Dynamic ListBox
A ListBox can implement generics for a dynamic set of columns and rows. Here's how:
http://www.hightechtalks.com/csharp/
Dear all,
Please can I make my listbox in a variable manner?
I have 3 listboxes and I want to make the number for listbox is a variable ?
I need to display an 2d-array in 3 listboxes .
for (int k = 0; k != array_cols; k++)
{ for (int i = 0; i != array_rows; i++)
{ arraytimes[i, j] = Multi;
Multi = Multi * 10;
listBox($k).Items.Add(arraytimes[i, k]); }}
Have you considered a ListBox that binds to generic Lists as the datasource? This design might be more efficient than a ListBox with variables that binds to an array.
List<dynamic> dynList = new List<dynamic>() {
new {Id = 1, Name = "Elevator", Company="Vertical Pop" },
new {Id = 2, Name = "Stairs", Company="Fitness" }
};
listBox.DataSource = dynList;
listBox.DisplayMember = "Name";
listBox.ValueMember = "Id";

Negative rowIndex for a DataGridViewRow
Negative rowIndex problem for new DataGridViewRow

I create and add a new row to an unbound DataGridView. Then, if I try and
access an item in the Cells collection of the row, as in my commented out
code, I get an index out of range exception, rowIndex. I'm not specifying a
row index, so I assume it is inferring it from the row object, whose
rowIndex property is -1. However, when I access the cell through a row in
the grids Rows collection, I'm happy, as in my other code. Can anyone
explain this behaviour?
The exception:
Specified argument was out of the range of valid values.
Parameter name: rowIndex
The code:
ExportLineRow newRow = new ExportLineRow(); // Derived from
DataGridViewRows.
newRow.ExportLine = newLIne;
newRow.CreateCells(dgvLayout);
dgvLayout.Rows.Add(newRow);
int cx = 1;
foreach (Column o in
newRow.ExportLine.RecordLayout.Columns.Values)

Hi Brady, With the DataGridView, the rows could be accessed iteratively up to a size of myGrid.Rows.Count Here is a webpage with an example of how to access a row/column reference as you describe. http://msdn2.microsoft.com/en-us/library/system.windows.forms.datagridview.rowcount.aspx On Jan 27, 2008 1:00 PM, Brady Kelly <brady <at> chasesoftware.co.za> wrote: > I create and add a new row to an unbound DataGridView.

Hi Kara, Thanks for the link, but I've determined my problem is somehow related to me trying to add row objects derived from DataGridViewRow. I suspect I'm not overriding a required member somewhere, because I can add one custom row, but all other rows after that break when I add them. > > Hi Brady, > > With the DataGridView, the rows could be accessed iteratively up to a > size of myGrid.Rows.Count > > > Here is a webpage with an example of how to access a row/column > reference as you describe. > > http://msdn2.microsoft.com/en- > us/library/system.windows.forms.datagridview.rowcount.aspx
