It is recommended that classic VB6 error handling be replaced
with structured exception handling.
But to answer your specific question: In the code, no specific value
is returned in the (empty) error handler.
Just put a "CreateFolder = False" line after the "Errors:" label.
Note: You can also write "Return <value>" instead of
"<function name> = <value>".

I dont program in VB.NET - but not all paths return a value because falling
into error before you set createFolder=True would fail to provide a return
value, and you need to return a bool.
Put CreateFolder = False in your error section. Better still - start using
try/catch statements and get rid of the goto

I'm sure he realises that, the question was as to why he *didn't* get a
compiler warning. I would have expected there to be one too.

Whoops. Misread the original post. .Net Reflector to the rescue.
This is what the code is turned into:
---snip---
Private Shared Function CreateFolder(ByVal sFileName As String) As
Boolean
Dim flag1 As Boolean
Dim num2 As Integer
Try
ProjectData.ClearProjectError
Dim num1 As Integer = 2
If Not Directory.Exists(sFileName) Then
Directory.CreateDirectory(sFileName)
End If
flag1 = True
goto Label_0066
Label_0025:
num2 = -1
Select Case num1
Case 0, 1
goto Label_005B
Case 2
goto Label_0066
End Select
Catch obj1 As Object When (?)
ProjectData.SetProjectError(CType(obj1, Exception))
goto Label_0025
End Try
Label_005B:
Throw ProjectData.CreateProjectError(-2146828237)
Label_0066:
If (num2 <> 0) Then
ProjectData.ClearProjectError
End If
Return flag1
End Function
---snip---
Dim flag1 As Boolean means that flag1 is implicitly initialized
to False by .Net.
So all code paths are indeed satisfied.
But it sure is ugly.

Looks like a normal behavior as all paths are likely returning a value as
all paths are ending with end function (and the implicit return value is
false). IMO you have rather this warning when you use the "exit function"
statement ??

A value is still returned even if not explicit so Im' not sure the warning

I've read a few of these answers that state something along the lines of: Just put a "CreateFolder = False" line after the "Errors:" label.
That should never be required. Since False is the default return value for
any boolean function/variable/whatever, explicitly setting the return =
False should never be required. If it is suddenly required after 30 years of
programming, there should be a huge notice posted on the web somewhere that
says "forget about your existing source code, everything has suddenly
changed for no good reason"

You could actually disable the warning. Simply open up the project file in
a text editor and add the warning number (42105) to the 'NoWarn' element.
My main concern is that the warning only occurs at functions which return a
reference type.
The full text of the warning makes this more clear: "[...] A null reference
exception could occur at run time when the result is used". I do not think
that implicitly returning 'Nothing' is a big problem. The main problem is
IMO forgetting to set a return value for a certain code path inside the
function. The same problem applies to BC42104 too. I have summed up my
thoughts on the usefulness of this warning in an article (in German):

It is true that the squiggly lines appear for

'Do nothing

but not for
Public Function ValueProducesNoSquiggleLines() As Boolean
Dim b As Boolean = True
End Function

Check the samples below. None of them produce squiggly lines, even
though I am fairly positive that they cover both objects and value
types as return values. I see no difference in behavior due to
the choice of return types.
If you look at what the compiler turns the samples into, you will
see that something is explicitly returned on all code paths in all
samples.

(last comment for tonight)
ok. I understand what you want.
But "On Error ..." is an abstraction that is turned into
something completely different (and much bigger).
I think what you are asking for would be extremely difficult
to implement - possibly basing the squiggly lines on something
different than what is being used by IntelliSense.
I am not qualified to speculate on how the
parser/compiler/IntelliSense
work their magic, so I'll leave this one alone.
/Joergen Bech
Herfried, totally agree with your comments, i suppose what i was getting at
is that if you start relying on the warning you can be misled into thinking
you are returning a value when you are not exlpicitly doing it. i know
specifying a value type as the return value will always return a value, hut i
would have expected the warning when there is a code path that does not
***explicitly*** return a value.
seems to me this an 'intermittent' warning and can be misleading.
