Re: How to change the ResultFormatType of the MathKernel in a ASP.NET Web Application?

Javier:

Since it has been either Todd or I responding to your questions, I left this 
one unattended because I just thought it was a repost.
I a way it is. But you are still having problems.

You are using Visual Studio 2003 and you still write out full Object paths 
for lack of a better word.

The sample I sent you in VB makes no reference to Global

I declare a variable MathKernel1 as New Wolfram...MathKernel (Created the 
Object called MathKernel1)

From then on I call MathKernel1  methods and set or get Properties.
See post on 3/9/2005

There is no Global in the VB code.

I think you are missing something fundamental. Copy all your code the 
machine generated stuff also. I'll review and get back to you.
