I am doing the following and getting an exception, any thoughts?

Dim endpoint As IPEndPoint = Nothing

endpoint = New IPEndPoint(&HC0A80201, 5000) '192.168.2.1

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred
in system.dll

Additional information: Specified argument was out of the range of valid
values.

I forgot that a new without parameters requires a parameterless
constructor.

Thanks.

&HC0A80201 extends range of integer. Use &HC0A80201L to express long(int64)
data.

It works without the L as well, but I agree it is
better to specify the L for clarity. The problem was
(I believe) that when we use new for that type we
must supply parameters because there is no definition
for new() only for new(param) etc.

Thanks.

Huh! Take a look at your code again... You are already calling the
parameterized constructor. The problem is definitely that VB.NET treats the
hex number as 'Int32' and treats it as a negative number.

Sorry, you are absolutely right. I'm afraid my program has other problems
as well, hence I did not see why the L *is* needed. Thanks, and apologies
and thanks to the first replyer too.

This may seem strange, but on dot net cf it *will* work
without the long cast.
