Trap and continue in Loop..

I have a routine that thumbnails an entire directory.
The problem is animated gifs or unsupported file types.
I cannot get this loop to continue if it bombs because of an err.number 481....
There has to be a way to increment and continue onto the next file...I have tried everything I can think of...

Public Sub SaveWholeFolder(sType As String)
For i& = 0 To frmDemo.List1.ListCount - 1
  fName$ = frmDemo.List1.List(i&)
  'On Error do what?
  frmDemo.picHidden.Picture = LoadPicture(fName$)
  Call StretchPic(frmDemo.picHidden, frmDemo.picMain)
  frmDemo.Caption = i&
  DoEvents
  x$ = Mid(fName$, InStrRev(fName$, "\") + 1)
  xx$ = Mid(x$, 1, InStr(x$, "."))
  xx$ = xx$ & sType
  Call SavePicture(frmDemo.picMain, App.path & "\Thumbnails\" & xx$)
Next i&

End Sub

Thanks

wouldn't something like this work?

Public Sub SaveWholeFolder(sType As String)
For i& = 0 To frmDemo.List1.ListCount - 1
 fName$ = frmDemo.List1.List(i&)
 On Error GoTo SkipMe
 frmDemo.picHidden.Picture = LoadPicture(fName$)
 Call StretchPic(frmDemo.picHidden, frmDemo.picMain)
 frmDemo.Caption = i&
 DoEvents
 x$ = Mid(fName$, InStrRev(fName$, "\") + 1)
 xx$ = Mid(x$, 1, InStr(x$, "."))
 xx$ = xx$ & sType
 Call SavePicture(frmDemo.picMain, App.path & "\Thumbnails\" & xx$)

 SkipMe:

Next i&

End Sub

check you tools-options-general tab - error trapping should be set to break in class module

The problem appears to be (always a file) in temp internet folder....Searching the drive the file does not exist....but my FindFiles routine is finding these strange "fake" gifs....that will always make it by the error trap...and lock the app.

can you call out to another routine?

Private Sub Command1_Click()
Dim ix As Integer

For ix = 1 To 100
dostuff ix
Next ix

End Sub



Private Sub dostuff(ix As Integer)
On Error GoTo handler:
'simulate error condition
If ix = 50 Then Err.Raise vbObjectError + 2002, "me", "test"
'the call that would actually generate the error
List1.AddItem ix
Exit Function
handler:
End Function
