an error. loquin03-07-2003, 09:35 PMIs it possible to have multiple "on error goto" statements going to different lines within the same procedure? I can't get the second On Error to work. Is there a way to do this? Thanks in advance! Yes, you should be able to do this with no problems. J-Man03-07-2003, 09:46 PMThe problem that I am having is if an error is encountered in the top "stuff", it goes to "This"...which is what I want it to vb6 msgbox do. However, if a second error is encounted in the bottom "stuff", the program crashes! It's like it doesn't recognize the second "On Error" for some reason. Any ideas? Can anyone else reproduce what I've explained? J-Man03-07-2003, 09:51 PMIn case anyone wanted some code that does this (for me): Private Sub Command1_Click() Dim a() As Integer Dim b() As Integer On Error GoTo This MsgBox UBound(a) This: On Error GoTo That MsgBox UBound(b) That: MsgBox "Made It!" End Sub loquin03-07-2003, 10:32 PMThis: Err.clear ' <<< Add this line On error goto that I'm thinking that if you don't clear the error, it may brcausing problems with the second on error. loquin03-07-2003, 10:35 PMOne thing though - the code here does nothing except skip aropund the failing code. Why not avoid the labels & gotos and just say On error resume next for this block of code? Optikal03-08-2003, 02:25 AMThe following code works as expected, try this: Private Sub Command1_Click() Dim a() As Integer Dim b() As Integer ReDim a(10) On Error GoTo This MsgBox UBound(a) On Error GoTo That MsgBox UBound(b) Exit Sub This: MsgBox "This" Exit Sub That: MsgBox "That" Exit Sub End Sub It will msgbox "10" and then "That" as expected. If you comment out the Redim line, it will msgbox "This" as expected... J-Man03-08-2003, 07:24 AMloquin, I simplified the code for my example....there's more to it than that. Thanks for your help!

Visual Basic Concepts Visual Studio 6.0 Error Handling Hierarchy An enabled error handler is one that was activated by executing an On Error statement and hasn't yet been turned off — either by an On Error GoTo 0 statement or by exiting the procedure where it was enabled. An active error handler is one in which execution is currently taking place. To be active, an error handler must first be enabled, but not all enabled error handlers are active. For example, after a Resume statement, a handler is deactivated but still enabled. When an error occurs within a procedure lacking an enabled error-handling routine, or within an active error-handling routine, Visual Basic searches the calls list for another enabled error-handling routine. The calls list is the sequence of calls that leads to the currently executing procedure; it is displayed in the Call Stack dialog box. You can display the Call Stack dialog box only when in break mode (when you pause the execution of your application), by selecting the View, Call Stack menu item or by pressing CTRL+L.

You can and should do all you can to prevent them, but when they happen you have to handle them. Introduction Trapping Errors at Run-Time Building http://codereview.stackexchange.com/questions/94415/try-catch-statement-in-vba-using-the-standard-vba-error-handling-statements Error Handlers Raising Your Own Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in Visual Basic expect to deal with certain types on error of data and behavior in your applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that it can use to derive a date. If you provide input that it can't convert, it raises error number 13 - "Type mismatch" - essentially on error goto saying "I can't handle this input data." In an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can examine the properties of the Err object to determine the nature of the error. Once the error has been dealt with, you use the Resume sta

(It works but I'm interested to know what other people make of it and for any suggestions you might like to make.) The most important facts to realise are: When you use on error goto Label1 the procedure enters into a state of "I'm handling an error" as an exception has been raised. When it is in this state, if another "On Error Goto" label2 statement is executed it will NOT goto label2, but raises and error which is passed to the code that called the procedure. You can stop a procedure being in the "I'm handling an error" state by clearing the exception (setting err to nothing so the err.number property becomes 0) by using Err.clear or On Error Goto -1 ' Which I think is less clear! (NOTE that On Error Goto 0 is different from the above) Also important to note is that Err.Clear resets it to zero but it is actually equivalent to: On Error Goto -1 On Error Goto 0 ie Err.Clear removes an "On Error Goto" that is currently in place. So therefore it is mostly best to use: On Error Goto -1 as using Err.clear You would often need to write Err.Clear On Error Goto MyErrorHandlerLabel I use the above techniques with various labels to
