Error when setting mySqlConnection's ConnectionString Property

[Bob Yuan]

I met an error of

"Object reference not set to an instance of an object" when I tried to set the connectionString property of a mySqlConnection component at design time.

I have already successfully added mySqlCommand, mySqlConnection and mySQLDataAdapter components from the .net connector to VS2003.

I did not have any other stuffs except a blank form in this project (C#). Is there anything wrong?

Thanks in advance.
