hey guyz am a student just studied c and trying to practice but can't seem to make my compiler work is there anywhere to get a c compiler better still java's and how do you use d java runtime enviroment just downloaded one pls try being explicit

I don't know if anyone needs the source code of my simple application that calculates the determinant of a 3 by 3 square maltrix.

I don't know if anyone needs the source code of my simple application that calculates the determinant of a 3 by 3 square maltrix.

You have tried man. Keep it up. I did exactly that, about 8 years ago when learning C. You can push it a little 4ward by use it to solve 3X3 simultaneous eqns. I mean real life situations like determining prices of known items.

Good luck.

Here is the code that converts amount in double to amount in words. I did it in C#. You may copy and use it if u like. It uses Nigeria currency :

Usage: AmountInWord(115.50) returns one hundred and fifteen naira fifty kobo only.

i think it will be better to share codes as attachments or using URL's eg. http://www.spiralteck.com

Long time! Cooking up something , Sorry, I was away for a long time.

Hi guys, long time no see. Been busy with lots of projects recently.
OK let share this sample code to send mail HTML page using gmail server in C#:

  private String readHtmlPage(string url)
        {
            if (!System.IO.File.Exists(url)) return string.Empty;

            try
            {
                String result;
                WebResponse objResponse;
                WebRequest objRequest = System.Net.HttpWebRequest.Create(url);
                objResponse = objRequest.GetResponse();
                using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
                {
                    result = sr.ReadToEnd();
                    sr.Close();
                }
                return result;
            }
            catch (Exception ex)
            {
                App.LogError(ex);
                return string.Empty;
            }
        }


private void SendMailBtn_Click(object sender, EventArgs e)
        {               
                string mail = readHtmlPage(url);
                if (mail.Trim().Length == 0) return;

                string toAddress = "to_one@yahoo.co.uk";
                string fromAddress = "someone@gmail.com";

try
{

if (fromAddress.Trim().Length == 0)
{
MessageBox.Show(this, "Cannot send mail from an empty address. Please confirm the setting email.", "Byaxiom SendMail", MessageBoxButtons.OK, MessageBoxIcon.Information);
return;
}
if (toAddress.Trim().Length == 0)
{
MessageBox.Show(this, "Cannot send mail to an empty address. Please confirm the customer email.", "Byaxiom SendMail", MessageBoxButtons.OK, MessageBoxIcon.Information);
return;
}

MailMessage msg = new MailMessage();
msg.IsBodyHtml = true;
msg.From = new MailAddress(fromAddress);
msg.To.Add(toAddress);
if (AppSettings.Default.EMailCopy.Length > 0)
msg.CC.Add("mycopyemail@yahoo.com";

msg.Subject = subject;
msg.Body = message;

SmtpClient mailClient = new SmtpClient("smtp.gmail.com", 587);
mailClient.EnableSsl = true;

mailClient.Credentials = cred;

mailClient.Send(msg);
MessageBox.Show(this, "Track report mail sent to " + toAddress + ". Please confirm by checking your mail copy", "Byaxiom SendMail", MessageBoxButtons.OK, MessageBoxIcon.Information);

@smark k

what would say is the best way of becoming a comptetent programmer in any choosen language. or could share scerets that has worked for you

thanks

@blacksta

i. Have genuine interest in programming
ii. Sincerely ask yourself if u have what it takes
iii. Be consistent. It takes time to get used to programming
iv. Always be prepared to go some extra-mile. Go a step higher than the next person
v. Always open ur mind. Never close ur mind door. U could always find a better way of doing it.

Hey, manage this for now. Thanx

I like this post and i think i have started something on this line before. Well I created a blog on www.youbanize.com recently because i wanted to create a place online to share programming experiences. I am a PHP programmer, a veteran in JavaScript and CSS. I have posted some of my codes in there;if you would like to share real experiences or learn from the experiences of others , you are welcome.

where can i get JDk and its product key to install

go to java.sun.com

Where can i get java file editor to download?

and I use Windows XP Professional 2008.make una help me out

He! long time.

Check me on http://kunlesmart..com for jQuery Cascading Dropdown plug-in.

You can let me know what you think, and if you have any problem using the guy.

Bless u.

How you dey? I love the code you provided, but really have not found any need for database mapping in my applications. Could u please give me some scenario. I really would like to know more about this stuff.

Thanx.

Note: I am not talking about creating classes that maps table fields.

I can't believe my eyes. This is the same old thread we used in those days when I was still a novice. I you check the first page of this thread you will see that I was unable to even parse a String to int but see me today, A near guru giving solutions to nairaland java problems. Thank you God. Starters in the house, work hard its the only road. I started out like you too.
@Smart K. Thanks for this thread.

I de kampe, how your side?
That code is not only useful for mapping. You will find that, at the very least, it can list all Sql Servers on a network.
More important though, if you wish to take it a little further, its an intro to SQL Server Management Objects (SMO). With SMO, you can do every single thing SQL Server is capable of, what I've submitted is just a peep in.

It is still used by 126 million players every month. The game's development started in 2009 when Markus Persson, the creator of Minecraft, released the Cave Game for PC. Get more interesting details about minecraft servers check it out.
