Error encountered when creating table with MS SQL and Visual Studio

Hi Experts,
I am new to MS SQL and I am using it with Visual Studio 2005. I was developing a simple system and tried creating a table but then I got this error message, see below. I have searched the web but couldn’t find a suitable answer. Any help I can get from the forum experts? Help will be much appreciated.

Query Definitions Differ
The following errors were encountered while parsing the contents of the SQL pane:
The CREATE TABLE SQL construct or statement is not supported
The query cannot be represented graphically in the Diagram and Criteria Pane.
