The debate, intentionally or unintentionally, seems to be working in favor of Microsoft, who obviously has vested interest in promoting ASP.NET. RedHat, Zope, and IBM are known as excellent paymasters to open source programmers and scout for talented programmers from open source community.

Perl is one of the most rooted scripting languages, and has wide range of libraries for any purpose.Nowadays I’m studying it, and exploring its great usage and ease of use.Perl has powerful string processing ability, and also when you have confidence in using regular expressions, you may achieve anything on parsing.Here I want to demonstrate its simple syntax.

\t : Tab Character
\n : New Line
\r : Carriage Return
\f : Form Feed Character
\cX : Control Character CTRL-X.  : Match any one character
| : Alternation
( ) : Group  / Also returns the values for $1 , $2 , $3 after proper matches.
[ ] : Define Character class^ : Match the beginning       $ : Match the end
\b : Match at a ”word” boundary  \B : Match at not a ‘word’ boundary

* : Match 0 or more times
+ : Match at least 1 or more times
? : Match 0 or 1 times

\d : [0-9] A digit            \D : A non-digit
\s : Whitespace char       \S : A non-whitespace char.

/i : ignore case    /g : Match globally (all matches)      /s : Substitute, Replace

=~ True If the regex matches        !~ True If the regex doesn’t match

The above information will be helpful if you have just started to learn Regular Expressions.

However you may not want to wait for Whidbey, yes it is said to be there exist some solutions, (I heard this from one my programmer friend). Surprisingly the idea seems very interesting to me. The point is that you call assembly functions from a DLL, so the only thing that differs is coding, you just call some functions to make your calculations in machine language, and as a result. you acquire the indispensable augmentation in performance.

Never tried this method, but I will definitely try, in the following posts I may expose it with some code samples. Another important point that you may use this method in VB.NET also, as you can use the DLL in a same manner. Goodbye until to next post!

For example, I am using GoDaddy’s shared hosting plans and I’m really happy with.However I am discovering the limits lately, and I am understanding what are you capable of to do with shared hosting using ASP.NET.Chances are that if you are using PHP, you have greater freedom and everything becomes possible.

Yesterday I was trying to connect to a MySQL database with .NET, I accomplished this on Windows very smoothly without having any problems.(I used ByteFX .NET library to connect MySQL).On the other hand, on Web, this is nearly impossible, you can not use external dlls on many of the shared hostings (security issue).I tried to use ODBC to connect MySQL, I didn’t use any DLLs and again I couldn’t connect to MySQL database (By the way this MySQL database is not on my shared hosting, on a completely different host), because thanks to GoDaddy, they have blocked outgoing connections to other database hosts.So I was only able to connect an inner MySQL database.You may ask why MySQL? Because you may not find free database hosts that give MSSql (there are lots of hosts that provides free MySQL databases), and also you may not have any other options other than MySQL, so in such a case your all hands are tied.

Briefly I am really considering to use PHP rather ASP.NET, day by day I discover something that is possible in all the way with PHP and not possible with ASP.NET.
This is really driving me nuts.As you see PHP gains another +1 against ASP.NET.See you next time…

Url rewriting can be made in few ways, with ISAPI modules, or you may configure IIS to direct .html or anyother extensions to ASP.NET dll. However you need to access your IIS server.If you are using a shared hosting like me , you may be disappointed but you should accept that you can only do url rewrites which ends in .aspx extension, because IIS directs .aspx extensions to asp.net dll, and your custom rewrites in your global.asax will run before IIS gives an “404 Not Found Error”.

Yes I hate .aspx/.php or any other extensions different than .html. Not only me prefer .html , but also Google prefers .html extensions, and most likely to index that pages.Briefly the same situation can happen if you host php on IIS (which is pretty a dumb action to do), as a result this is not related but .NET, but again If we consider php/apache bros. they gain +1 against asp.net/IIS .

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
MessageBox(NULL, “Goodbye, cruel world!”, “Note”, MB_OK);
return 0;
}

Yes, this is a way of saying “Hello World” in win32 api
Maybe I’ll add some small tools in the future if I can learn, it is pretty hard and complicated.

Why Threading?
-Because threading is really useful, and it is used in nearly all kind of serious softwares, threads enables us to do independent jobs simultaneously, and it is sometimes hard to handle, if it is done with experienced hands, it enhances the software greatly. I want to give a simple example, consider you want your program to check for available updates and install them without interrupting the user’s work. This is only done with threads, while user working with your software, another thread connects to Internet and checks available updates without blocking the current execution of the software.

A simple threading example with C# :

Thread test_thread;

public void Thread_Task()
{
for(int i=0;i<100:++i)
TextBox1.Text=Convert.ToString(i);
}
private void button1_Click(object sender, EventArgs e)
{
test_thread=new Thread(new ThreadStart(this.Thread_Task));
test_thread.IsBackground = true;
test_thread.Start();
}

In the above simple code piece, we created a thread object and a thread task function, then we assigned task function to thread object in a button_click function, then we started the thread, as you notice, if user clicks the button a new thread starts and show the value of i in the TextBox1 without blocking the program, user may continue working and at the same time values of i are showed in the TextBox1. This was a sample example to demonstrate threads created and used, besides there is a vast usage and restrictions for threads, for example there will be a problem what if two threads wants to access the same resource and wants to edit, there are lots of synchronization problems and techniques.

I am here to put a C# implementation of it, I do not care if someone is interested in or not, I feel I could give this away, do what you want with it… Comments are welcome as always.

public string getmxserver(string hostname)
{
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.UseShellExecute = false;
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = “nslookup”;
proc.StartInfo.Arguments = “-type=mx ” + hostname;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
StreamReader pout = proc.StandardOutput;
string s = pout.ReadToEnd();
string[] snew = s.Split(‘,’);
string[] snew2 = snew[1].Split(‘=’);
string[] snew3 = snew2[1].Split(‘ ‘);
string[] snew4 = snew[1].Split();
string mxserver = snew4[4];
return mxserver;
}

As you can see it is the simplest way of Getting MX record. I hope this would be helpful to those who are intended in coding SMTP client.

MailMessage mymes = new MailMessage();
mymes.To.Add(new MailAddress(toTextBox.text);
mymes.From=new MailAddress(fromTextBox.text);
mymes.Subject=subjectTextBox.text;
mymes.Body=bodyTextBox.text;
SmtpClient myclient = new SmtpClient(“smtp server host address as string”);
myclient.Send(mymes);

It is easy as it is. It is extremely short and easy to understand (8 lines as you see), the complexity may emerge, if the smtp server needs authorization and maybe it need a ssl connection to authorize username & password (credentials). I leave those to ones who are interested in more than a simple stmp client, if you have any question or help please leave a comment.
