It's not experimental software, and they do release a stable build now and then.
You'll find that most stuff is available, up to .NET 4.0. The MonoDevelop IDE doesn't come with a WinForm-designer, you'll have to build your forms from code, or switch to GTK# which would come with a small learning-curve because it works a bit different from WinForms.

I have written a login page but each time I login it returns a blank page even with a wrong password please help:
the login page is as follows:
<body>
<div id="wrapper">
<form action="methods/login.php" method="post">
<ul>
<li><label>Username:</label><input type="text" name="username" size="10" value="<?php echo htmlentities("$username"); ?>" /></li>
<li><label>Password:</label><input type="password" name="password" size="10" value="<?php echo htmlentities("$password"); ?>" /></li>
<li><input type="submit" name="login" value="Log In" /></li>
<li><input type="submit" name="join" value="Join" />
</ul>
</form>
</div>
</body>
</html>
and the php login script is
<?php
require_once("../includes/ikobe.php");
if (isset($_POST['username']) &&isset($_POST['password']))
{
$username = $_POST['username'];
$password = $_POST['password'];
$pass = sha1($password);
if (!empty($username) &&!empty($password))
{
$query = "SELECT 'id' FROM 'users' WHERE username= '$username' AND password='$pass'";
if ($query_run = mysql_query($query))
{
$query_num_row = mysql_num_rows($query_run);
if ($query_num_row==0)
{
echo 'Invalid username / password combination';
}
else if ($query_num_row==1)
{
echo 'ok.';
}
}
}
else
{
echo 'You must supply a username and password.';
}
}
?>
any help will be greatly appreciated

I believe your MySql query may be failing, causing you to see nothing other then a blank page. Your code seems weird to me as you escape strings the same way as you do column names and table names, which is a nono for MySQL.
If you want to escape table / column names use the query below instead.
"SELECT `id` FROM `users` WHERE username= '$username' AND password='$pass'"

I have changed the query script and done a var_dump it returns the values entered but it still does not run the query script even with a wrong password.
-<?php
require_once("../includes/ikobe.php");
if (isset($_POST['username']) &&isset($_POST['password']))
{
$username = $_POST['username'];
$password = $_POST['password'];
var_dump($username,$password);
$pass = sha1($password);
if (!empty($username) &&!empty($password))
{
$query = "SELECT 'id' FROM 'users' WHERE username= '$username' AND password= '$pass'";
if ($query_run = mysql_query($query))
{
$query_num_row = mysql_num_rows($query_run);
if ($query_num_row==0)
{
echo 'Invalid username / password combination';
die();
}
else if ($query_num_row==1)
{
echo 'ok.';
}
}
}
else
{
echo 'You must supply a username and password.';
}
}
?>
No idea how because if you dont enter any fields it returns the error of supply username and password?
any help anyone ??

The default PHP.INI error notify settings are set to NOT DISPLAY. Check out DEVELOPER SETTINGS in error notify and enable it. By default the production setting is recommended.
Also instead of tightly locking your application to MySQL, use Adodb Abstraction Library for PHP (http://adodb.sourceforge.net/[^])

That should work I think.
- Removed quotes from 'id'
- I added "LIMIT 1" to your query to only return a maximum of one result.
You should also:
- "Salt your passwords"
- Clean Input using mysql_real_escape_string()

Thanks alot for all the input I have tried a couple of the solutions. I have had different outcomes
with the same result. At the moment I am using Marc Firth's solution and getting
"-Invalid username / password"
with a wrong or correct password.
With no values entered it returns
"You must supply a username and password."
Am not really good at reading and understanding the "IF" "ELSE" working but would appreciate if someone
gives a clue to what to do.

Try to output the hashed (sha1) password, and compare it to the one in the database. i.e. for user "joe" with password "bloggs" run the following code and compare the output to the mysql query below
First get the hash you are creating when you log in (notice the "die"):
<?php
require_once("../includes/ikobe.php");
if (isset($_POST['username']) && isset($_POST['password'])) {
$username = $_POST['username'];
$password = $_POST['password'];
$pass = sha1($password);
die($pass);
if (!empty($username) && !empty($password)) {
$query = "SELECT id FROM users WHERE username = '$username' AND password='$pass' LIMIT 1";
$query_run = mysql_query($query);
$query_num_row = mysql_num_rows($query_run);
if (mysql_num_rows($query_run) == 0) {
echo 'Invalid username / password combination';
} else {
echo 'Ok.';
}
} else {
echo 'You must supply a username and password.';
}
}
?>
Then compare it to the one in the database:
<?php
$query = "SELECT password FROM users WHERE username = 'joe' LIMIT 1";
$query_run = mysql_query($query);
while($row = mysql_fetch_array($query_run)){
echo $row['password'];
}
?>
The two results should match.

This works (tested):
<?php
session_start();
mysql_connect('localhost', 'user', 'pass');
mysql_select_db('dbname');
if (isset($_POST['username']) && isset($_POST['password'])) {
$username = $_POST['username'];
$password = sha1($_POST['password']);
if (!empty($username) && !empty($password)) {
$query_run = mysql_query("SELECT id, password FROM users WHERE username = '$username' AND password = '$password' LIMIT 1");
if (mysql_num_rows($query_run) == 0) {
echo 'Invalid username / password combination';
} else {
echo 'Ok.';
}
} else {
echo 'You must supply a username and password.';
}
}
?>
<form action="" method="post">
<label>Username:</label>
<input type="text" name="username" size="10" value="<?php echo htmlentities("$username"); ?>" />
<label>Password:</label>
<input type="password" name="password" size="10" value="<?php echo htmlentities("$password"); ?>" />
<input type="submit" name="login" value="Log In" />
<input type="submit" name="join" value="Join" />
</form>

I am using Ubuntu 10.04 LTS with OpenConnect to connect to my work (Cisco VPN). All was working fine and today morning it just fails 'Error fetching SSL response. SSL connection failed).
I am sure they are using a self-signed SSL which has been working fine all along. Any ways to fix this issue?

Any ways to make Google Unicode (Tamil/Hindi etc) fonts to appear properly in Chrome (Ubuntu Linux). Installed the Microsoft TTF fonts as suggested in Ubuntu forums by experts but to no avail yet. I admit:: I have restarted the system too not just the GUI.

Does Tamil or Hindi text appear correctly elsewhere (e.g.) Firefox or not? I.e. is the problem limited to Chrome?
With Ubuntu, you can install the Hindi and Tamil localisations of the operating system. Also the fonts will be installed.

Firefox is no problem. Only Chrome is a headache.

Goto fonts & encodings settings, and change all the fonts to use Tamil Unicode font. I mean the Serif and Sans Serif drop downs. That should be good enough.

Can some one share a few tips on what are the unneeded services that could be removed off in Ubuntu 10.04 (LTS) and Ubuntu 11.04 when using like a personal desktop operating system? The typical use of the computer would be the following:
1) Moderate use of Geany -- Programming IDE
2) Light to Moderate use of MySQL 5.1
3) Moderate use of Apache (for PHP)
4) Google Chrome (for Internet Browsing)
I am pretty sure not to require those bloated services like cron, Akonadi, KDE crap which are annoying my old resource-challenged computer.

KDE on a resource challenged computer?
I'd suggest to move away from Ubuntu. Try something like Arch Linux with simple desktop environments like XFCE.

Easy, install a bare version of Debian, then install things such as X Windows and then a Desktop like XFCE. (Ubuntu is basically a rebranded version of Debian.)
See if you can crack this: b749f6c269a746243debc6488046e33f
So far, no one seems to have cracked this!
