a minute: Sign up VBA On Error Exit Calling Function up vote 0 down vote favorite 1 I have a simple excel function that connects to a db and retrieves some data and populates a worksheet. The function calls another https://msdn.microsoft.com/en-us/library/5hsw66as.aspx function to make the db connection and return the query results. How do I exit the calling function if there is an error connecting to the database? This is what my function looks like that connects to the DB. If there is an error connecting to the DB, the messagebox is displayed but then processing resumes in the calling function and then I get an ugly "END or DEBUG" message box...which I am trying to avoid.

End Function You may want to handle your errors in the calling sub though since errors "bubble up" to the caller. This will cause your macro to debug even though you have an error handler in QueryDB. Here is an example of how you can handle errors in called functions Sub Main() On Error GoTo DBERROR QueryDB ("Query String") On Error GoTo 0 Exit Sub DBERROR: MsgBox "Oops!

generally put more focus on the coding part and getting the desired result but during this process we forget an important thing i.e. Error handling. Error handling is an important part of every code and VBA On Error Statement is an easy way for handling unexpected exceptions in Excel Macros.
