I am creating a template with multiple columns that will be populated by
others. Some of these columns have specific character limitations--in these
cases I'd like to prevent them from going over the character limit. I've
considered using validation, but there is an excellent chance that some of
the columns will be populated by copying/pasting, in which case validation
doesn't help. I thought vba might be the best bet. What I'd love to have is
this:

If the person types or copies a value that exceeds the character limit, I
would like a general message to display saying something like, "You have
exceeded the character limit. Entries that exceed the limit will be
highlighted and truncated." Then I would like that to happen--that is, to
have their entry truncated to the max character limit, and that cell
highlighted. I would like to have this work whether they pasted in one cell
or multiple cells at a time. Does anyone have any ideas how I could
accomplish this? Any guidance would be appreciated.

Thanks,

Jeff

Hi,

See if this gets you started. Checks for data entered into column A

HTH

Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo wsexit
Application.EnableEvents = False
If Not Intersect(Target, Range("A:A")) Is Nothing Then
Set rng = Target
For Each cell In rng
If Len(cell) 10 Then
MsgBox "You have exceeded the character length. Cell will be
truncated"
cell.Value = Left(cell.Value, 10)
Target.Interior.ColorIndex = 3
End If
Next
End If
wsexit:
Application.EnableEvents = True
End Sub

Just a heads up,
Unless it was Toppers intent to color the entire target if any cell in the
target exceeded the length limitation, then the following line

Target.Interior.ColorIndex = 3

should be changed to
Cell.Interior.ColorIndex = 3

to color only the offending cells within the cells changed

But perhaps "Target" was his intent.

also, if the only restriction was to column A, you could use

set rng = Intersect(Target, Range("A:A"))
rather than
set rng = Target

No intention to criticize Topper's Excellent suggestion, just some
additional refinement suggestions.

Thanks Tom, it should be Cell not Target. Your comments are always welcome
.... that's how I learn!

Right click on the sheet where you want the behavior. Select View Code.
This takes you to the sheet module.

At the top of the resulting module
In the left dropdown, select Worksheet and in the right dropdown select
Change (not selection change)

this will add the declaration for the change event.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)

End Sub


As you can see, this is the event that Topper used. It fires whenever a
cell is edited or data is pasted. You can now delete the Change declaration
that was entered by excel and paste in Topper's code.

You don't have to do the dropdowns to paste in the code - I just when
through that description as a form of instruction.

For general information on events, see Chip Pearson's page on them

Toppers, thanks a bunch! This code looks to be exactly what I need. I
tried
setting this up but have run into a problem. I am a newbie to vba and I'm
having trouble running this code. First of all, does this code
automatically
run each time changes are made to the worksheet, or does the user need to
run
the macro after they are done populating it? Second, I opened the Visual
Basic Editor and copied your code (with the change made by Tom) into a new
module in the workbook. When I attempt to run the code by going to
ToolsMacrosMacros, it does not appear in "This Workbook" or "All Open
Workbooks". When I reopen the VB Editor, it shows up in my module. With
the
VB Editor open with the module active, I can't even run it. When I press
run, it asks me to create a new macro. This seems really weird, but I
havn't even been able to test the code. Do you have any ideas?

Jeff
