// All the standard and custom objects in the Org

// Make the describe call
Schema.DescribeSobjectResult[] results = Schema.describeSObjects(entityNames);
System.debug('Got describe information for ' + results.size() + ' sObjects.');

// Checking if there is a formula field with Javascript used in Hyperlink formula function

		// cannot be used for security reasons
