CodeInsight helps you with the Show Error Messages option
Choose the Show Error Messages option on the CodeInsight page of the Editor Options dialog box (Tools|Editor Options) to get extra help from CodeInsight. When this option is selected, if MemberInsight or ParameterInsight pop-up windows can't be displayed due to compiler errors, CodeInsight expands the error node in the structure pane to display the errors. Also, if there is additional information, the main status bar shows a short message, such as &quot;Unable to determine type of expression.&quot;
