This really isn't that complex :-)

	^[a-zA-Z]+\-[a-zA-Z]+$

starts (^) with one or more (+) alpha characters
	followed by one literal `-` character
		followed by one or more (+) alpha characters
			end of string ($)

By comparison, this example of yours

objRegExpr.Pattern = "^[a-zA-Z]*[\-]*[a-zA-Z]$"

starts with zero or more alpha characters (that matches *any* string)
	followed by zero or more `-` characters (ditto)
		exactly one alpha character
			end of string
HTH!
