Trapping Errors
If you keep coming up with problems in your applications and you
don't want error messages to be popping up when the user causes
an error then all you need to do is add an error handler.
On Error ...
There are two options from here. You can either get it to ignore
the error or do something else that sorts the error out. If you
just want the error to be ignored use this:
On Error Resume Next
This will simply execute the next line of code after one with the
error on. This could stop your application doing something important
but lets face it, if there is an error it isn't going to do it anway.
Usually it is just used then there is a problem such as when you
are using the web browser control and a user clicks back when there
is no page to go back to. This would normally bring up an error
box but by adding in the code it stops this from happening.
Your other alternative is to add in a GOTO command to send the
code to do something else if it finds an error. Take a look at this
example:
On Error Goto 10
WebBrowser1.GoBack
Exit Sub
10 ' error bit
MsgBox ("Error!")
' some code to sort it out
End Sub
