Time entry with VBA

M

MartinW

Hi all,

I've never bothered with VBA, simply because I haven't
had a need. I've always been able to do anything I need
with worksheet functions (and the groups help of course).

Now I'm developing a sheet where it will come in very handy.
Chip Pearson's Time entry worksheet change event fits the
bill very nicely. (I'll post it at the end of this thread)

All I need is to input time values as follows

123 converts to 1:23
445 converts to 4:45
12 converts to 0:12
etc.

Chip's code works great for the range A1:A10.
All I need to do is expand on this so that it works
on multiple ranges and individual cells

Say for example;
A1:A10
C1:C12
F4:H20
A15:A17
B22:C26
G25
D34
F34
H34
etc.

How do I go about adapting the code to work in these
multiple ranges only.

Thanks to all
Martin

Here is Chips code.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim TimeStr As String

On Error GoTo EndMacro
If Application.Intersect(Target, Range("A1:A10")) Is Nothing Then
Exit Sub
End If
If Target.Cells.Count > 1 Then
Exit Sub
End If
If Target.Value = "" Then
Exit Sub
End If

Application.EnableEvents = False
With Target
If .HasFormula = False Then
Select Case Len(.Value)
Case 1 ' e.g., 1 = 00:01 AM
TimeStr = "00:0" & .Value
Case 2 ' e.g., 12 = 00:12 AM
TimeStr = "00:" & .Value
Case 3 ' e.g., 735 = 7:35 AM
TimeStr = Left(.Value, 1) & ":" & _
Right(.Value, 2)
Case 4 ' e.g., 1234 = 12:34
TimeStr = Left(.Value, 2) & ":" & _
Right(.Value, 2)
Case 5 ' e.g., 12345 = 1:23:45 NOT 12:03:45
TimeStr = Left(.Value, 1) & ":" & _
Mid(.Value, 2, 2) & ":" & Right(.Value, 2)
Case 6 ' e.g., 123456 = 12:34:56
TimeStr = Left(.Value, 2) & ":" & _
Mid(.Value, 3, 2) & ":" & Right(.Value, 2)
Case Else
Err.Raise 0
End Select
.Value = TimeValue(TimeStr)
End If
End With
Application.EnableEvents = True
Exit Sub
EndMacro:
MsgBox "You did not enter a valid time"
Application.EnableEvents = True
End Sub

Toppers

one way:

Create a named range with all your sub-ranges included: "MyRange"

and change code:

If Application.Intersect(Target, Range("MyRange")) Is Nothing Then

Untested!

Some code posted earlier (from Hesham ELhadad )on a similar question about
non-contiguous ranges .. might be useful:

You can divide the Range as you need as follows:

Sub CreateMyRange()
Dim MyRange As Range

Set MyRange = Application.Union(Range("A1:A24"), Range("A26:A47"),
Range("A49:A100"))
MyRange.Select ' Just to confirm the defined range. you can remove
this line later
MyRange.Name = "MyName"

End Sub

Thanks Toppers,

Your first solution was all that was needed. Amazed I didn't
think of that as I use it in all sorts of situations in other worksheets.
I guess my mind just goes blank at the mention of VBA.
Some sort of psychological disfunction or something. <g>

Thanks
Martin
