The type '_Default' is ambiguous

Hi,
How do you solve this problem, I seen a web page about this but I still very
new to asp.net so please elaborate thanks ?

Hi, basically it is saying that there are two objects called _Default and
you are wanting to use one of them but it does not know which one to
instantiate.
Use the namespace of the _Default object you want to use when you reference
the object in your page (Find which one by using the object browser to
browse the referenced objects (Dlls)).

I see that you are not the only one having this problem

Hi, take a look at this link re namespaces

http://www.csharphelp.com/archives/archive99.html

The problem you are having is that an object is being instantiated by your
application and the compiler does not know which class to use.

The way around that is to explicitly specify the namespace that the class is
associated with

e.g. If I created an image object in code and I had referenced the
System.Drawing namespace in my project then I would receive a similiar error
because the compiler does not know if I want a image object (Ala drag and
drop from the IDE) or a System.Drawing.Image object.

To make it clear that I wanted a System.Drawing.Image object I would have to
explicitly tell the compiler that (To avoid ambiguity, hence your error
message)

so instead of doing this

image myImage = new image...

I would go
System.Drawing.Image = new .... etc

I am explicitly telling the compiler what type of image object I want to
instantiate.

I jsut removed "inherits="_Default"" and it works fine. I have no special
need for
it. So just removeing this from the

<%@ page language="VB" autoeventwireup="false"
solves the problem.
