My JS console was showing the above errors

replace_element.insertAdjacentHTML is not a function       tiny_mce.js (line 1)

this.contentWindow has no properties            tiny_mce.js (line 1)

So it was something related to tinymce. Well that was my problem but for the same reason you might encounter another error…So, what’s the fix for this problem?

Since last time this tinymce worked I did one change to Firefox indeed. I’ve changed the user agent and looks like that broke the JavaScript.

So, if you have this problem, type about:config in your Firefox and search for general.useragent.extra.firefox. Make sure this has a value something like this Firefox/2.0.0.1. Also, lookup for general.useragent.override and make sure it has an empty value. If you can’t find this last one than there’s no problem.

Hope this helped somebody out there!

SMTP it’s a simple protocol used for sending electronic messages on internet.SMTP use the 25 TCP port and obtain the address of a SMTP sever using a MX(Mail Exchange) record from the DNS server configuration.

The SMTP protocol specify the way that a electronic message is transfered between SMTP process that are on different systems.The SMTP process that initiate the transfer is called client and the SMTP process that receive that process is called SMTP server. It’s not so important here the way that the message is sent from the client to the server or the way that the server send the message to destination.

History

SMTP protocol was used especially at the begin of ‘80 years. That tine it was used less than UUCP(Unix to Unix CoPy) because that was just perfect for sending messages between systems permanently connected. Anyway SMTP works better for sending electronic messages when the client and the server are permanently connected to a network. First program that implemented the SMTP protocol was Sendmail. From 2001 on there was other programs that implemented that protocol: Postfix, Qmail, Novell, GroupWise, Exim, NetMail and Microsoft_Exchange_Server.

How it works…

Communications between client and server is done using ASCII texts.Initially the client establish the connection with the server and wait for server responding with “220 Service Ready”. From any reasons the server can send this message lately.When the client receive that 220 message he sent a HELLO command and that way he is unfolding his identity.When the connection was establish the client can send one or more messages, can close the connection or can user other services like verifying the mail adress. The server must respond after each command indicating this way that the command was accepted or if there are errors.

For sending a message the client use the MAIL command for specifying the client address. If this command is ok the server respond with “250 ok” message. Then the client send RCPT command for specifying the receiver address. The server respond with “550 No such user here”, or “250 OK”, depending by command validity.When the server accept the command the client send DATA command and that means that the client is starting sending the message content.In this moment server can respond with “503 Command out of sequence” or “554 No valid recipients” message. If server respond with “354 Start mail input” message then the client can start sending the message content. The end of the message will be tagged by <CR><LF>.<CR><LF>.

A SMTP sever must know:

- HELO - the client identity

- EHLO - client identity by large request

- MAIL FROM - client specification

- RCPT TO - receiver specification

- DATA - message content

- RSET - reset

- QUIT -finish the session

- HELP - help for command

- VRFY - verifying an address

- EXPN - expanding an address

- VERB - detailed informations

The function of the SMTP protocol can be tested by initiating a TCP connection using a telnet client:

telnet mailhost.domeniu.ro 25
Server: 220 mailhost.domeniu.ro ESMTP
Client: HELO host.domeniu.ro
Server: 250 Hello host.domeniu.ro
Client: MAIL FROM: user@domeniu.ro
Server: 250 Ok
Client: RCPT TO: user@altdomeniu.ro
Server: 250 Ok
Client: DATA
Server: 354 End data with <CR><LF>.<CR><LF>
Client: Subject: test
Client: un mesaj test
Client: .
Server: Mail queued for delivery.
Client: QUIT
Server: 221 Closing connection. Bye.

If you have java applets or other java applications and you want to connect them with standard SQL databases like SLQ Server, Oracle, Informix, Sybase and others JDBC is the one who can help you to do that.The combination of Java’s JDBC and standard SQL makes a simple and powerful database solution. Using JDBC things are easy without making the complex tasks too difficult either.

During this article we’ll teach you haw to establish a connection between your java applications and SQL data base and we’ll do that step-by-step to understand better.

Obtaining the JDBC driver

For using JDBC you need to install the JAVA JDK. If you don’t have it already installed you can download it(free) at Sun’s Java web site .Also many IDE’s have already integrated it so you have nothing more to do just to use.Next thing you have to do is to obtain correctly the JDBC driver.In most cases the JDBC driver will be provided by your database vendor.Once you have this driver you have to install it.

Establishing a connection is a two-step process

If you installed the JDBC driver correctly it’s very easy to establish the connection between java application and the SQL database. So for establishing that connection you have to follow the next two steps:

- Load the JDBC driver.

- Establish the connection.

For undestanding better what you have to do we give you an example:

//  Establish a connection to a mSQL database using JDBC.import java.sql.*;class JdbcTest1 {        public static void main (String[] args) {        try {            // Step 1: Load the JDBC driver.

            Class.forName(”com.imaginary.sql.msql.MsqlDriver“);

            // Step 2: Establish the connection to the database.

            String url = “jdbc:msql://www.myserver.com:1114/contact_mgr“;

            Connection conn = DriverManager.getConnection(url,”user1″,”password”);

        } catch (Exception e) {

            System.err.println(”Got an exception! “);

            System.err.println(e.getMessage());

        }

    }

}

The JDBC Driver

The name of the JDBC driver will be supplied to you by your database
vendor. As you can see in the class.forName() statements, these
names will vary.

The URL

The syntax of the DriverManager.getConection() method is: DriverManager.getConnection(String url, String username, String password);

Username and password are used for login to the data base.

The first version of Microsoft ASP.NET was 1.0. Since then the team worked for introducing possibilities to create web applications that had the ability to upload files to the hosting server. This was done through the use of the FileField HTML server control. Now we refer to the 2.0 version of ASP.NET.This article try to introduce you to the new FileUpload server control.

FileUpload Server Control Example

If you want to use the FileField control in ASP.NET 1.x version you must know that you had to take a few extra steps to get everything in line and working. In ASP .NET 2.0 version things are ease to be done. The new version of FileUpload server control makes the process of uploading files to the hosting server as simple as possible.

I will show you how to use the FileUpload control to upload files to the server. Here are two examples of using FileUploade: one of them is wrote in Microsoft Visual Basic and the other one in Microsoft Visual C#:

Visual Basic Example:

<%@ Page Language="VB" %>

<script runat="server">
    Protected Sub Button1_Click(ByVal sender As Object, _
      ByVal e As System.EventArgs)
        If FileUpload1.HasFile Then
            Try
                FileUpload1.SaveAs("C:Uploads\" & _
                   FileUpload1.FileName)
                Label1.Text = "File name: " & _
                   FileUpload1.PostedFile.FileName & "<br>" & _
                   "File Size: " & _
                   FileUpload1.PostedFile.ContentLength & " kb<br>" & _
                   "Content type: " & _
                   FileUpload1.PostedFile.ContentType
            Catch ex As Exception
                Label1.Text = "ERROR: " & ex.Message.ToString()
            End Try
        Else
            Label1.Text = "You have not specified a file."
        End If
    End Sub
</script>

<html  >
<head runat="server">
    <title>Upload Files</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:FileUpload ID="FileUpload1" runat="server" /><br />
        <br />
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click"
         Text="Upload File" /> <br />
        <br />
        <asp:Label ID="Label1" runat="server"></asp:Label></div>
    </form>
</body>
</html>

Visual C# Example:

<%@ Page Language="C#" %>

<script runat="server">
    protected void Button1_Click(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile)
            try
            {
                FileUpload1.SaveAs("C:Uploads\" +
                     FileUpload1.FileName);
                Label1.Text = "File name: " +
                     FileUpload1.PostedFile.FileName + "<br>" +
                     FileUpload1.PostedFile.ContentLength + " kb<br>" +
                     "Content type: " +
                     FileUpload1.PostedFile.ContentType;
            }
            catch (Exception ex)
            {
                Label1.Text = "ERROR: " + ex.Message.ToString();
            }
        else
        {
            Label1.Text = "You have not specified a file.";
        }
    }
</script>

<html  >
<head runat="server">
    <title>Upload Files</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:FileUpload ID="FileUpload1" runat="server" /><br />
        <br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click"
Text="Upload File" /> <br />
<br />
<asp:Label ID="Label1" runat="server"></asp:Label></div>
</form>
</body>
</html>

Running this you will obtain the source code generated from the FileUpload control:

<html  >
<head><title>
   Upload Files
</title></head>
<body>
    <form name="form1" method="post" action="MyFileUpload.aspx"
     id="form1" enctype="multipart/form-data">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJNDcxNTg5NDg3D2QWAgIEDxYCHgdlbmN0eXBlBRNtdWx0aXBhcnQvZm9yb
       S1kYXRhZGQUQEUFMY1+/fp1mnrkbqmVNQIzFA==" />
</div>

    <div>
        <input type="file" name="FileUpload1" id="FileUpload1" /><br />
        <br />
        <input type="submit" name="Button1" value="Upload File"
         id="Button1" /> <br />
        <br />
        <span id="Label1"></span>
    </div>

<div>

   <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION"
    value="/wEWAgLB+7jIAwKM54rGBv2Iz6LxVY7jWec0gZMxnuaK2ufq" />
</div></form>
</body>
</html>

As you can see ASP.NET 2.0 modified the page’s<form > element on your behalf by adding the appropriate enctype attribute. Another important thing to remark here is that the FileUpload control was converted to an HTML <input type="file" > element.
If you run the file from the examples you can upload files to the server by clicking on the Upload File button and selecting the file that you want to upload and that’s a very ease job.

As an online business, the people may be familiar with the available utilize “pay for performance”. Also known as pay-per-click, PPC or paid search, it has faithful taken the online marketing world flood especially the two largest player, Overture and Google Adwords. A study by Piper Jaffray tell that paid search constitutes more than 87% of U.S. search market revenues. This wonderful statistic demand the question:”Are advertisers achieving a positive return on their paid search investment?”

The answer to this question may forbid from understanding the role of the two critical performance metrics.

Click-through Rate (a.k.a. CTR) = Click-throughs (i.e. Total Visitors) / Impressions

For example, if your paid search ad is seen by 10 users and one user clicks on your ad.Website conversion is defined of users who want to visit your website and complete your primary objective.

Website Conversion (a.k.a. sales conversion) = Sales / Click-throughs (i.e. Total Visitors)

So what role does each play in understanding the effectiveness of a paid search campaign?
Standard practice between advertisers is to concentrate a high click-through rate to send more visitor traffic to their website.

A trigger is a stored procedure that automatically executes when an event occurs in the database server.Triggers execute when users try to modify something or behind an event that generate changes on the data base.There are three kind of triggers: for insert , update , and delete.The most important events correspond to Transact-SQL CREATE, ALTER, and DROP statements, and certain system stored procedures that perform DDL-like(data definition language) operations.Triggers can be created in the SQL Server 2005 Database Engine directly from Transact-SQL statements or from methods of assemblies that are created in the Microsoft .NET Framework common language runtime (CLR) and uploaded to an instance of SQL Server.Using SQL Server you can create lots of triggers for any specific statement.

Syntax:

CREATE TRIGGER trigger_nameON { ALL SERVER | DATABASE }

[ WITH <ddl_trigger_option> [ ,...n ] ]

{ FOR | AFTER } { event_type | event_group } [ ,...n ]
AS { sql_statement  [ ; ] [ ,...n ] | EXTERNAL NAME

< method specifier >  [ ; ] }<ddl_trigger_option> ::=

[ ENCRYPTION ]

[ EXECUTE AS Clause ]

<method_specifier> ::=

assembly_name.class_name.method_name

schema_name

Is the name of the schema to which a DML trigger belongs. DML triggers are scoped to the schema of the table or view on which they are created. schema_name cannot be specified for DDL or logon triggers.

trigger_name

Trigger name is the name of the trigger. Is not allowed to start the trigger name with # or ##.

table/view

Table or view are the table or view where trigger is executing on.Triggers cannot be defined on local or global temporary tables.

DATABASE

Current data base where changes are making on.

ALL SERVER

Is the current server where are the tables or views that we make changes.If specified, the trigger fires whenever event_type or event_group occurs anywhere in the current server.

WITH ENCRYPTION

Using WITH ENCRYPTION prevents the trigger from being published as part of SQL Server replication.

EXECUTE AS

Specifies the way is executed the trigger.This way users validate permissions on any database objects that are referenced by the trigger.

FOR | AFTER

After - means that trigger can be executed only after all operations specified in the triggering SQL statement have executed successfully.

event_type

Is the type of event that release the trigger for executing.

sql_statement

Is the trigger conditions and actions. Trigger conditions specify additional criteria that determine whether the tried DML, DDL, or logon events cause the trigger actions to be performed.The trigger actions specified in the Transact-SQL statements go into effect when the operation is tried.

method_specifier

The method must take no arguments and return void. class_name must be a valid SQL Server identifier and must exist as a class in the assembly with assembly visibility. If the class has a namespace-qualified name that uses ‘.’ to separate namespace parts, the class name must be delimited by using [ ] or ” ” delimiters. The class cannot be a nested class.

Points to consider while designing a website layout

When you create a website is very important to consider that you may change something on the site and that must be an easy job. That’s why:

Keep it simple:

In major situations a simple website layout is user friendly. It’s better to not create complex navigational links using complex scripts or images that may not be viewable correctly in different browsers. It’s also very possible that search engine to not index the site properly if complex navigation is involved. You should use small icons to attract visitor’s attentions because using larges images cam make your website difficult, laborious.

Readable font size and face:

We recomand you to use standard font size of “-1” (11 or 12 pixels if using styles) because that way visitors can read the content easily. Select a professional looking font face (Verdana, Arial, Helvetica, sans-serif are very common). Avoid using fancy fonts like Comic Sans (unless it is a personal website). Use appropriate spacing between lines (12 or more pixels) to avoid clumsiness.

Use web safe eye pleasing colors:

You must select that color you feel are best for you website subject. However, it is a wise decision to get feedback from users or friends about what they feel about the color combination of the website.

  Web pageDimensions:

Here, an important thing is to keep track of dimensions of a web page. Most successful commercial websites limit the width and height of the web page so that the important content of the web page lies within the top 600×600 viewable area without scrolling. The best choice is to limit the width by placing a table with a fixed width of 750 or 775 pixels and to work in this table. The page height should not be any more than 4 scroll lengths. Limit the content of the page and if more content needs to be added, move it to a new web page. Provide a navigational link to the next page and a link back from the second page. This will also increase your web site’s page views.

Tips & tricks

Extract JavaScript code and styles from within the HTML page to external .JS and .CSS files. To decrease you individual HTML page size create a link from each HTML page to these external files because browsers download these files only once and caches them on the user’s computer. Use server side includes for centralizing common content, use a background which creates a contrast to the font colors and graphics and why not look at media sites to inspire.

There are lots of advanced features that have been added for your convenience. Photoshop CS 2 is not merely content to correct your photos or make graphics, but its goal is to supply you with everything you need to make your images the most vivid they can be. This latest version introduces powerful new tools for creative design and photography as well as refinements on all the old traditional favorites. With Photoshop CS 2 they introduce new levels of power, precision and control with a combination of revolutionary features and evolved enhancements.

Photoshop CS 2 has lots of new features like the next generation file browser Adobe Bridge, Vanishing Points, non-destructive Image Transformations (smart objects), Image Warp and 3 new filters for common photographic problems. Many of us can say that is complicated, or they never use all its features but you never know when you need them and you will use, so that is not a drawback is an absolute advantage. When you have a look at the work area there are many different types of tools. This makes Photoshop appear similar to most other products but, what you don’t see, is all the hidden tools and all the hidden functionalities for these tools which make image editing or graphic design a whole lot less complex.

It’s very important when you have to work with a picture or with different parts of a picture to be able to select the part of the picture that you want to edit. What makes Photoshop so easy to use is all the different sub functions that you can learn about which helps you select the exact thing you want to edit and thus streamlining the editing process. The acclaimed Photoshop file browser, Adobe Bridge, has evolved into its own application that runs fully independently, thus allowing you to multi task between organizing, editing and processing your images by adding Scalable Thumbnails, Enhanced Ranking and Labeling, and a Slide Show Mode for a quick review of your latest shoot.

The Bridge also integrates with Illustrator and InDesign and all the other applications in the creative suite. It is very important to mention some unparalleled new traits, new things from which we can learn how to use the Photoshop Training course. For example we can use this appliance to match new perspectives, new longterm, say how you can have a family portrait and another very important things which should be known by the user.
Photoshop can show you how to remove this clutter very easily. Also known as Smart Object, Photoshop is a destructive o creative transformation who can show you how you transform images without loosing important pixel. They also have Smart Guides who can control the movement of the copies which you will create.

Many times there’s a big need to redirect different URL’s on your website to other places. The reason for this can be very different, but the idea is same. We need a reliable way of doing that. Off course that can be done in a “script wise” manner; I mean, if your website is dynamic, upon loading a specific page, the requested URI could be checked against a database redirects collection and if found there, the specific redirect would be issued ( be it a 302 moved temporarily redirect, 301 Permanent redirect, etc. ). That’s beyound the purpose of this article.

So what would be a simple solution to do a temporary/permanent redirect on dynamic URL?

Since I was asked by many peoples over this website and other places to present a way of doing redirects of dynamic URL’s using .htaccess, I decided to put here a way that I found useful.

So here it is the following htaccess file:

RewriteEngine onRewriteCond %{QUERY_STRING} ^page=1$

RewriteRule ^(/)?$ http://mywebsite.com/url_to_go_to [R=301,L]

Basically that would do the trick, and would issue a 301 Redirect of /?page=1 to http://mywebsite.com/url_to_go_to. If you try that you’ll notice a small problem which really is not a problem: The URL to where it gets redirected will be: http://mywebsite.com/url_to_go_to?page=1. Notice that the query string is automatically appended to the new URL. That can be prevented by ending the URL to be redirected to with a ? mark, as stated in the Apache mod_rewrite documentation, where there is explained the query-string-clearing function.

“ When you want to erase an existing query string, end the substitution string with just the question mark “

If you are trying to redirect an URL like /index. php?page=2 to something like http://www.mysite.com/page/2 , than you can use the power of regular expressions combined with Apache features.

This will look something like the above:

RewriteEngine onRewriteCond %{QUERY_STRING} ^page=([0-9]*)$

RewriteRule ^(/)?$ http://mywebsite.com/url_to_go_to/page/%1? [R=301,L]

Notice the ? sign at the end of the new URL for clearing the query string.

Hope someone will find this article useful. Enjoy

CSS 3 eliminated the need of Photoshop when it comes to add a shadow to a text. A shadow offset is specified with two length terms that indicate the distance from the text:

• The first length term specifies the horizontal distance to the right of the text. We can use negative values which place the shadow to the left of the text.

• The second length term specifies the vertical distance below the text. Also we can have a negative vertical length term which places the shadow above the text.

A blur radius may be specified after the shadow offset. The blur radius is a length value that indicates the boundaries of the blur effect. After setting the blur radius we can add the color.

Let’s have some examples:

1) The example below will set a text shadow to the right. This is a simple example and we can easily observe that no color has been specified meaning the shadow will have the same color as the element itself, and no blur radius is specified meaning the text shadow will not be blurred:

h2 { text-shadow: 0.3em 0.3em }

2) The next example will place a shadow to the right and below the element’s text. The shadow will have a 4px blur radius and will be blue.

h2 { text-shadow: 3px 3px 4px blue}

3) The next example combine more effects specifing a list of shadow effects. The first shadow will be to the right and below the element’s text and will be blue. The second shadow will overlay the first shadow effect, and it will be yellow, blurred, and placed to the left and below the text. The third shadow effect will be placed to the right and above the text.

h2 { text-shadow: 3px 3px blue, yellow -3px 3px 2px, 3px -3px }

4) Take a look at this example:

.shadow {

background: white;

color: white;

text-shadow: black 0px 0px 5px;

}

Here the background and the text has the same color (white) and the shadow is black. This shadow effect added makes the text to be visible.

Note This property is not defined in CSS 1. It is possible not to have a text shadowed if we work with agents using CSS 1. This feature isn’t new in CSS 3, it was put into CSS 2 but only got implemented in Opera 9.5 and Safari 3 so far.
