Locking cels using a UDF

I'm not entirely sure if this is possible or not... but here we go.

I'm looking to lock down two cells in a row after data is input into the
cells... for the entire spreadsheet... or at least 2000 rows. I think the
easiest way would be to have a function since I could fill down and the two
cells would change relative to the position of the function.

Basically, I'm looking to lock cells A1:B1 and so on all the way down the
spreadsheet. I've seen some subroutines to lock cells, but I don't know how
to use them in the spreadsheet, and I'm having a heck of a time trying to get
this to work.

I'd appreciate any help. Thanks.
 
Can't do it with a function, but with event code

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "G2:H2000"

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
.Locked = True
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

Awesome, Thanks a million man. Really needed to know how to use the
subroutines, thanks again.

Just a note here.

The cells will still be editable until you Protect the Worksheet.

Yep, found that out. Played around with it a bit, but I got it to do what I
wanted finally... I decided I wanted to do the same thing for another set of
cells in two other columns... as well as protect the page so the cells
couldn't be altered after entering data, here's what I have working. Wooga!

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "A2:B2000"
On Error GoTo ws_exit:
Application.EnableEvents = False
ActiveSheet.Unprotect Password:="1"
If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
.Locked = True
End With
End If
ActiveSheet.Protect Password:="1"
ActiveSheet.EnableSelection = xlUnlockedCells

ws_exit:
Const WS_RANGER As String = "H2:I2000"
On Error GoTo ws_exit2:
Application.EnableEvents = False
ActiveSheet.Unprotect Password:="1"
If Not Intersect(Target, Me.Range(WS_RANGER)) Is Nothing Then
With Target
.Locked = True
End With
End If
ActiveSheet.Protect Password:="1"
ActiveSheet.EnableSelection = xlUnlockedCells

ws_exit2:
Application.EnableEvents = True
End Sub

Only thing further is to have only the unlocked cells able to be selected
when the program opens... since they seem to be reverting back to editable
once the file is re-opened.

Thanks a bunch!!

Haven't tested your code, but looks impressive and you say it does the job.

Goodonya.
