Thanks for replying.
I'm running this within AutoCAD & don't have the Office Reference ticked.
I'm confused why it would be a specific Excel problem.
Isn't IsNumeric a general
VB command?
Is there a way to prevent it happening?
I'm trying to allow only positive numeric values being typed & displayed in
a textbox:
If IsNumeric(OffsetNo) = False Then ' if there is a value in the
textbox & it's not a number
OffsetNo = Left$(OffsetNo, Len(OffsetNo) - 1) ' remove last typed
TxtBx_Dist.Value = OffsetNo ' & put it back in the box
End If
Cheers

Because Excel knows how to convert it to a number
? clng("45-")
-45
which is the defninition of isNumeric.
Many accounting applications indicate negatives by using the notation you
show.

Hi
I'm using VBA 6.3
If I pass 45- to this:
If IsNumeric(OffsetNo) = False Then
...
it returns True.
1) Why?
2) How do I prevent this happening?
Thanks in Advance.
