Firefox 3.0 now supports showModalDialog()


Javascript function window.showModalDialog() is used to create a modal dialog box that displays the specified HTML document. A modal dialog box, is kind of dialog box which retains the focus while open. The user cannot switch back to parent windows until the dialog box is closed.

This works fine in Internet explorer 4.0 and later version of IE but with Firefox 2.0 or below version it was not working. But there is a good news now that Firefox 3.0 supports showModalDialog() function.


Check out this link..


Test this page in Firefox 2 and Firefox 3



Chrome (Google's new browser) also supports showModalDialog().

Fetch random rows through SQL Query

If you need to fetch random rows from a SQL server table and you have an integer column then using RAND() function goes well. However in some cases there is no number column. In such cases how to fetch random rows? SQL Server provides one more mechanism to access random rows:

SELECT TOP <n>
FROM <table>
WHERE <criteria>
ORDER BY NEWID()

The key is the use of NEWID() function that returns a GUID.

As for example:

SELECT TOP 10 * FROM Products ORDER BY NEWID()
