I guess it started in C then. Made it's way to Java, then to C#. I'm not too familiar with C. But I have been working with Java for the last couple yrs.


>>In C# the entire clause after the "if" needs to get surrounded with parenthesis. Thanks to Java for that one. Not sure why Java does it that way.

>>> if (this.chkAutoRequery.Checked == true)
