Let’s learn ColdFusion …

ColdFusion is a simple language to learn and use primarily because it employs a tag-based syntax, which makes the transition between HTML (the language that your Web browser uses to render content) and CFML (ColdFusion Markup Language, the language that ColdFusion uses to generate that content from dynamic data) within your code very natural. Take, for example, the following HTML listing of companies (no CFML is in this code):




<td>The Very Big Corporation of America</td>




<td>Ma's Homemade Pies</td>




<td>Shecky Records</td>



By using ColdFusion's tag-based syntax, you can easily generate this table dynamically from data stored in your database (the CFML is boldfaced in the following example), as follows:

<cfquery name="GetCompanies" datasource="MyDatabase">

SELECT CompanyID, CompanyName

FROM Company



<cfoutput query="GetCompanies">







Basically, ColdFusion performs a query against the MyDatabase datasource (an object that connects to and communicates with a database) and names the data result set (the data that results from performing the query) GetCompanies. Then, for each row in the GetCompanies query, ColdFusion outputs the HTML markup used to format an HTML table row containing two table cells. The first table cell contains the value of CompanyID, and the second table cell contains the value of CompanyName from the current row in the result set.

How to get indexed by Google & Yahoo

I have seen a lot of ads and services online that provide the facility to get higher page ranks on search engines. But when I asked about those services on Google their respond was not much positive because they said it can decrease you page rank (because those services cannot be trusted always). It is happening because the page rank is depending on page visitors (as Google say). So the better way is to let the Google to index your site by sending them the address of your website. : here you can improve the traffic with the webmaster tools and you can send your website contents also. It is a legal, simple and direct hit.
You can send your web site address (even the blog) to Yahoo: also. It helps them to index your pages on their search engines.
