Vba Error Handling Best Practices
it only takes a minute: Sign up VBA Error Handle - Resume and print error up vote 0 down vote favorite I'm trying to build an structure like this below. where I have a loop and sometimes one of the loop steps can return error but I want to skip it and continue loop till the end. But if any

of the loops execution had error I want to know it printing in a cell something like "Missing loads: ( 1 ,20 ,36)" Where this number are unique values that one of my variables on the loop receive. So I think every time one of my loop executions return error I need to build a list of this variable value and at the end of the loop process use this list to return this error msg. UPDATE: For the below I want to know the list of any eventual "sProdId" value that was in the SQL query wen it fail to execute by ANY error. Usually it try to insert #Value in a numeric SQL field. Sub SavetoSQL() Dim conn As New ADODB.Connection Dim iRowNo As Integer Dim Ddate Ddate = Range("refdate") Dim RngRefdate As Date RngRefdate = DateSerial(Year(Ddate), Month(Ddate), Day(Ddate)) With Sheets("Hist Prods temp") 'Open a connection to SQL Server conn.Open "Provider=SQLOLEDB;Data Source=XXXXX;Initial Catalog=XXXXXX;User Id=XXXX;Password=XXXXXXX;" 'Skip the header row iRowNo = 2 'Loop until empty cell in sRefDate Do Until .Cells(iRowNo, 1) = "" sRefDate = .Cells(i

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 ... ... some other code ... ... some code http://stackoverflow.com/questions/1038006/good-patterns-for-vba-error-handling 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 23k145265 asked Jun 24 '09 at 12:17 jwoolard 2,51062534 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 constant E_NOTIMPL = &H80004001. Option Explicit Sub HandleError() Dim a As Integer On E
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value where only a positive number http://www.cpearson.com/excel/errorhandling.htm is acceptable; and run time errors, that occur when VBA cannot correctly execute a program statement. We will concern ourselves here only with run time errors. Typical run time errors include attempting to http://allenbrowne.com/ser-23a.html access a non-existent worksheet or workbook, or attempting to divide by zero. The example code in this article will use the division by zero error (Error 11) when we want to deliberately raise an vba error error. Your application should make as many checks as possible during initialization to ensure that run time errors do not occur later. In Excel, this includes ensuring that required workbooks and worksheets are present and that required names are defined. The more checking you do before the real work of your application begins, the more stable your application will be. It is far better to detect potential print error message error situations when your application starts up before data is change than to wait until later to encounter an error situation. If you have no error handling code and a run time error occurs, VBA will display its standard run time error dialog box. While this may be acceptable, even desirable, in a development environment, it is not acceptable to the end user in a production environment. The goal of well designed error handling code is to anticipate potential errors, and correct them at run time or to terminate code execution in a controlled, graceful method. Your goal should be to prevent unhandled errors from arising. A note on terminology: Throughout this article, the term procedure should be taken to mean a Sub, Function, or Property procedure, and the term exit statement should be taken to mean Exit Sub, Exit Function, or Exit Property. The term end statement should be taken to mean End Sub , End Function, End Property, or just End. The On Error Statement The heart of error handling in VBA is the On Error statement. This statement instructs VBA what to do when an run time error is encountered. The On Error statement t
a full version of Access, while a run-time version just crashes. For a more detailed approach to error handling, see FMS' article on Error Handling and Debugging. The simplest approach is to display the Access error message and quit the procedure. Each procedure, then, will have this format (without the line numbers): 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label to resume after error. 5 Exit Sub|Function ' Exit before error handler. 6 Err_SomeName: ' Label to jump to on error. 7 MsgBox Err.Number & Err.Description ' Place error handling here. 8 Resume Exit_SomeName ' Pick up again and quit. 9 End Sub|Function For a task where several things could go wrong, lines 7~8 will be replaced with more detail: Select Case Err.Number Case 9999 ' Whatever number you anticipate. Resume Next ' Use this to just ignore the line. Case 999 Resume Exit_SomeName ' Use this to give up on the proc. Case Else ' Any unexpected error. Call LogError(Err.Number, Err.Description, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom function to write the error details to a table. This allows you to review the details after the error has been cleared. The table might be named "tLogError" and consist of: Field Name Data Type Description ErrorLogID AutoNumber Primary Key. ErrNumber Number Long Integer. The Access-generated error number. ErrDescription Text Size=255. The Access-generated error message. ErrDate Date/Time System Date and Time of error. Default: =Now() CallingProc Text Name of procedure that called LogError() UserName Text Name of User. ShowUser Yes/No Whether error data was displayed in MsgBox Parameters Text 255. Optional. Any parameters you wish to record. Below is a procedure for writing to this table. It optionally allows recording the value of any variables/parameters at the time the error occurred. You can also opt to suppress the display of information about the error. Function LogError(ByVal lng
