'on error goto 0' in VBA?

Vba Resume
0 disables any error trapping currently present in the procedure. On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled.

It is interesting to point out that ONLY On Error Goto -1 will allow further error trapping within error trapping. Infact, even On Error Resume Next will still result in an untrapped error that halts operation. –Daniel Jan 4 '13 at 15:32 Thank you both so much, @Francis Dean and Daniel Cook. I've ended up using this in my code a long time ago, but never knew why

By default Excel on error deals with these, so when a run-time error occurs, you'll see a default error message like this: But you can change this and instruct Excel to allow your code to deal with run-time errors. NOTE : I’m going to use the terms sub, function and procedure interchangeably. For the purposes of this article they all mean the same thing – a chunk on error goto of code written to do a particular thing. The On Error Statement To instruct Excel what to do when an error occurs, you use the On Error statement. You can use On Error in four ways: On Error GoTo 0 On Error Resume Next On Error GoTo [label] On Error GoTo -1 On Error GoTo 0 This is the default mode and is already turned on when you start writing your code. You don’t need to use an On Error GoTo 0 statement at the start of your VBA. In this mode VBA displays the standard style error message box, and gives you the choice to Debug the code (enter VBA editor and use debugging tools) or End code execution. You would use On Error GoTo 0 to turn default error handling back on if you have previously told VBA to deal with errors in some other way e.g. by using On Error Resume Next. On Error Resume Next On Error Resume Next tells VBA to continue executing statements immediately after the statement that generated the error. On Error Resume Next allows your code to co
and receiving the Centigrade temperature in return. Another good technique is to break down a complex program into many small steps. Put the steps in functions with a boolean return value and then have the main program call each step. An example of two lines in your main program would be: 'if Step1 returns false, then go to errHandler1 If Not Step1("Financial Data", 100, 4) _ Then GoTo errHandler2 'if Step2 returns false, then go to errHandler1 If Not Step2("SomeOtherStuff", 5, 2) _ Then GoTo errHandler3 The first line simply says that if function Step1 is false then the method in Step1 has failed and go to errHandler2. If Step1 is true then the method in Step1 has succeeded and continue on to Step 2. Below is the code for 1 procedure and 2 boolean functions. Sub ComplexProgram() 'on error in ComplexProgram, go to errHandler1 On Error GoTo errHandler1 'if Step1 returns false, then go to errHandler1 If Not Step1("Financial Data", 100, 4) _ Then GoTo errHandler2 'if Step2 returns false, then go to errHandler1 If Not Step2("SomeOtherStuff", 5, 2) _ Then GoTo errHandler3 Exit Sub errHandler1: 'Notify user of failure. 'and possible suggestions. MsgBox "ComplexProgram has failed internally", _ vbCritical, "Program Failure" errHandler2: 'Notify user of failure. 'and possible suggestions. MsgBox "Step1 of ComplexProgram has failed", _ vbCritical, "Program Failure" errHandler3: 'Notify user of failure. 'and possible suggestions. MsgBox "Step2 of ComplexProgram has failed", _ vbCritical, "Program Failure" End Sub The Step1 function: c The Step2 function. Function Step2( _ ByVal intFinancialData As String, _ ByVal intNumberofRows As Integer, _ ByVal intNumberofColumns As Integer) _ As Boolean On Error GoTo errHandler1 'Set initial value to False until it finishes. Step2 = False 'Much of your code (especially methods) 'goes in this area. For example, 'this code could be to call your 'method to add a table in Word 'with 5 rows and 2 columns. 'If it completes all the code above 'without error then Step2 = True Exit Function errHandler1: 'Notify user of failure. 'if err.number = 1 then 'add additional possible solutions 'for error 1 to the msgbox below. MsgBox "Step2 has failed for error2 reason", _ vbCritical, "Program Failure" 'if err.number = 2 then 'add additional possible solutions 'for error 2 to the msgbox below. MsgBox "Step2 has failed for error2 reason", _ vbCritical, "Program Failure" End Function Home Programming VBA Topic Index
