This is due to Java script files using same named variables as those used by the Microsoft.NET AJAX Library. Hence causing the error

‘top.document.documentElement’ is null or not an object

JOIN Types the following is a summary of http://www.tek-tips.com/faqs.cfm?fid=4785

**********************************************************
– INNER JOIN
**********************************************************

Ex.
SELECT Team.Name, Matches.id
FROM Team INNER JOIN
Matches ON Team.id = Matches.HomeTeam

Note:
Returns all rows in which a column on the left table matches one on the right.

**********************************************************
– OUTER JOIN
**********************************************************
1) LEFT OUTER JOIN:
Ex.
SELECT Team.Name, Matches.id
FROM Team LEFT OUTER JOIN
Matches ON Team.id = Matches.HomeTeam

Note:
Similar to the INNER JOIN except that for all records in which a column does not exist for the left hand side table a NULL is returned

2) RIGHT OUTER JOIN
Ex.
SELECT Team.Name, Matches.id
FROM Team RIGHT OUTER JOIN
Matches ON Team.id = Matches.HomeTeam

Note:
RIGHT OUTER JOIN – This JOIN is just like the LEFT OUTER JOIN except the Right_Table is the table that will have every one of its records in the result set and if no record is found in the
Left_Table then its columns in the result set will be NULL

3) FULL OUTER JOIN
Ex.
SELECT Team.Name, Matches.id
FROM Team FULL OUTER JOIN
Matches ON Team.id = Matches.HomeTeam

Note:
FULL OUTER JOIN – This JOIN is a combination of both. All records from both Left_Table and Right_Table are in the result set and matched when they can be on the Join_Condition when no record is found in the opposit table NULL values are used for the columns.
So a query of

Also discusses the adding of Javascript to a page using the

Dim script As String = “[Label1ID].innerHTML = ‘boo!’;”
Dim scriptKey As String = “SayBoo”
Dim addScriptTags As Boolean = True

Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As EventArgs)

script = script.Replace(“[Label1ID]”, Label1.ClientID)

ClientScript.RegisterStartupScript( _
Me.GetType(), scriptKey, script, addScriptTags _
)

End Sub

usemap

URL

Defines the image as a client-side image map. Look at the ‘map’ and ‘area’ tags to figure out how it works
