Vba Error Handling Function
only takes a minute: Sign up Error handling in a Class Module Function up vote 4 down vote favorite I have several Class Modules in my Workbook. One of public functions in Class Module 1 relies on data from a
Vba Error Handling Exit Sub
function in Class Module 2, this happens four times. In the event that the object is missing from Class 2 the program crashes (as expected). I am having difficulty debugging the code properly as it seems that I can only exit the program from the main subroutine. I would prefer to kill the program from the Class function, but I don't know if that is possible (we can squash this here if it is). I am currently using On Error vba access error handling statements in the main subroutine, but these don't execute in a timely manner because the function in Class 1 gets data from Class 2 four times. Class Module 1 Function Function oload(ByVal pload As Double, ByVal cord As cCordCol, ByVal grid As cGridCol) ' cord is a scripting.dictionary of Class Module Objects (cCord) ' grid is a scripting.dictionary of Class Module Objects (cGrid) n1 = grid.Item(pg1).toGlobal(cord) n2 = grid.Item(pg2).toGlobal(cord) n3 = grid.Item(pg3).toGlobal(cord) n4 = grid.Item(pg4).toGlobal(cord) ' do something here oload = sum_Ploads End Function Above the n1 thru n4 is where I am calling on the public function of Class Module 2. Below is the Class Module 2 Function Function toGlobal(ByVal cord As cCordCol) On Error Resume Next ctype = cord.Item(Me.cord1).sys ' Missing Coordinate System Error If Err.Number <> 0 Then i = MsgBox("The definition of Coordinate " & Me.cord1 & " was missing from the Bulk Data " & Chr(10) & _ "File. Include this Coord in the .bdf and re-execute the program.", vbOKOnly, "Runtime Error") ' *** TERMINATE MAIN SUBROUTING HERE *** End If This will raise a message box indicating that an object was missing, specifically the (me.cord1) part - this is an item in a scripting.dictionary. I want to terminate the program here. The main subroutine (greatly reduced) is here: Sub main() ' lookup Element ID, Calc OLOAD, Sum Load Set OLOAD On Error GoTo PROC_ERR If dict_quad.Exists(EID) Then dict_oload.Item(LS).add_to_oload (dict_quad.Item(EID).oload(pload, dict_cord, dict_grid)) If dict_tria.E

In particular, what should I do in this situation: ... some code ... ... some code where an error might occur ... ... some code ... ... some other code where a different error might occur ... ... http://stackoverflow.com/questions/1038006/good-patterns-for-vba-error-handling some other code ... ... some code that must always be run (like a finally block) ... I want to handle both errors, and resume execution after the code where the error may occur. Also, the finally code at the end must ALWAYS run - no matter what exceptions are thrown earlier. How can I achieve this outcome? exception vba exception-handling share|improve this question edited Apr 15 '13 at 8:22 Atif Aziz 23k145165 asked Jun 24 '09 at 12:17 jwoolard 2,50562534 add a comment| 9 Answers 9 active oldest votes up vote 69 down vote accepted Error Handling in VBA On Error Goto ErrorHandlerLabel Resume (Next | ErrorHandlerLabel) On Error Goto 0 (disables current error handler) Err object The Err object's properties are normally reset to zero or a zero-length string in the error handling routine, but it can also be done explicitly with Err.Clear. Errors in the error handling routine are terminating. The range 513-65535 is available for user errors. For custom class errors, you add vbObjectError to the error number. For not implemented interface members in a derived class, you should use the const
