Time Input Mask

[brett]

I am trying to enter excercise time into a spreadsheet and want to be able to
enter time without having to type the colons. For example: 2 hrs 15 min 05
sec would be 2:15:05, or 45 min 34 sec would be 0:45:34. I could not find a
way to do it without changing the vb code (if anyones knows a way to do it
that way, it's my preference). So, I found this set of code, but it does not
allow for entry quite the way I want it. I would time entered as 3445 =
0:34:45; 13453 = 1:34:53. Any suggestions on how to edit the vb to make that
happen would be much appreciated. Thanks.

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

On Error GoTo EndMacro
If Application.Intersect(Target, Range("G2:G372")) 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)
