// CSource::Find
//
// Find the specified event source.  This is done by searching either
// the tree or the list control depending on the bSearchTree parameter.
//
// Parameters:
//		BOOL bSearchTree
//			TRUE if the tree should be searched, otherwise the list control
//			is searched.
//
//		CString& sText
//			A string containing the text to search for.
//
//		BOOL bWholeWord
//			TRUE if this is a "whole word" search.  False if it
//			is OK to match a partial word.
//
//		BOOL bMatchCase
//			TRUE if a case-sensitive comparison should be used.
//
// Returns:
//		BOOL
//			TRUE if the string was found, FALSE otherwise.  If the specified
//			text is found, then the selection is set on the corresponding
//			item, the item is scrolled into view and the focus
//			is set on the item.
