I am writing a very simple HTML code which is listed below. Written in notepad and opening in IE-8 and Firefox (OS: Window Vista).

&lt;html&gt;
&lt;body&gt;
    &lt;table border="1"&gt;&lt;tr&gt;&lt;td&gt;test&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;
&lt;/body&gt;
&lt;/html&gt;


There is nothing special in the above code, It is creating some space from top left corner.



Which can be easily removed by using the following code

&lt;body style="margin:0; padding:0"&gt;


Now i have find out the default margin and padding, which is 4 for Firefox and different for IE-8. 

&lt;body style="margin:4; padding:4"&gt;


I have some question on this scenario.


Why this value is 4?
From where this value is coming, is it saved somewhere?
Can we modify (configurable) this default value?
How these values are different for browsers? 


Thanks.


Question: Going round in Circles..Buffering/ArcObjects/VBA
Answer: Halil,

The interface you are using to create the buffers IFeatureCursorBuffer2 creates buffers for selected features.  Your point that you create based upon the users button click is not a feature but a graphic which you are adding to the graphics container of the map. A Feature is essentially a row in a table or featureclass.

As you are adding your point as a graphic I assume the buffer you want to create will also end up as a graphic. Use the interface ITopologicalOperator and it's method Buffer to create a polygon then do as you did with your point, create a graphic element.
