web browser "back" button

Afternoon all. I am putting together a small web browser application and I have a problem with the "back" button. If I navigate to a website then click back twice I get an error (can't remember at the moment what the error message was). I think it is happening because there is no site to navigate "back" to. So what I really want to know is how would I say "if there is no site then disable the back button"?

I tried and it didn't work:

if wb_browser.navigate = false then
cmd_back.enable = false
else
wb_browser.navigate (URL)
end if

I've not used VB in a few years and I expect this is really simple so I appreciate any light you can shed on this.

Cheers,

Would this help?

Code:

If URL = "" Then
  cmd_back.enable = false
Else
  wb_browser.navigate (URL)
End If

Or

If Len(URL) = 0 Then
  cmd_back.enable = false
Else
  wb_browser.navigate (URL)
End If
