Forms - Verify date format
 

Hi All,

I have a form to input staff details and l am having trouble verifying the
date format. The staff details exist on 1 Excel sheet in a "database" and
when the form is lauched the existing details are displayed in the form. The
DOB column is formatted as dd/mm/yyyy as is the short date in the systems
regional settings.

The code below is a snippet of the full code but is flawed in that:

1) As it is it crashes on the IF, OR, Then statement for cmbHREnter_Click
2) If l dont declare the variable type it runs fine but if the user
overwrites the date it is written to Excel in the incorrect format

Can anybody please tell me where l am going wrong as l have spent hours
trying to correct this problem. All comments gratefully received.

Dim DOB As Date
Dim Nino As String
Dim Surname As String

Private Sub UserForm_Initialize
tbDOB.Text = ActiveCell.Offset(0, 3).Value
End Sub

Private Sub cmbHREnter_Click()
DOB = tbDOB.Value
If Nino = "" Or _
Surname = "" Or _
DOB = "" Or _
Then
MsgBox ("One of the compulsory fields is blank. Please re-enter")
Else
ActiveCell.Offset(0, -1).Value = Nino
ActiveCell.Value = Surname
ActiveCell.Offset(0, 3).Value = DOB
End If
End Sub

Michael:

I think that it is because you are testing DOB as a string and not a date.

DOB = "" Or _

Try testing the value in the cell ie:

len(tbDOB.Value) = 0 ' no text in the box.

Tom,

Many thanks. That solved the problem of the IF, OR, THEN statement crashing
however l still get the wrong date format.

For instance if the original date displays in the Excel sheet as 08/09/1955
when the form launches it is in the same format. If the user then enters
11/12/1955
it is written to Excel as 12/11/1955.

I have tried modifying the code using FORMAT ie the code now reads as
follows:

Dim DOB As Date
Dim Nino As String
Dim Surname As String

Private Sub UserForm_Initialize
tbDOB.Text = Format(ActiveCell.Offset(0, 3).Text, "dd/mm/yyyy")
End Sub

Private Sub cmbHREnter_Click()
if isdate(tbDob.Value) then
DOB = cdate(tbDOB.Value)
else
DOB = 0
end if
If Nino = "" Or _
Surname = "" Or _
DOB = 0 Or _
Then
MsgBox ("One of the compulsory fields is blank. Please re-enter")
Else
ActiveCell.Offset(0, -1).Value = Nino
ActiveCell.Value = Surname
ActiveCell.Offset(0, 3).Value = Format(DOB, "dd/mm/yyyy")
End If
End Sub

Any ideas ? This is proving to be a right so and so......................

the reason I used cdate is that it understands the regional date setting.

when you use format and assign the cell the value as a string, you cancel
that out and ask vba to interpret the date which it does using US Centric
interpretation.

If you use
ActiveCell.Offset(0, 3).Value = DOB

as I suggested, where DOB was set with

DOB = cdate(tbDOB.Value)


then it should work for you.

I don't know the point of using format with ActiveCell.Offset(0,3).Text

tbDOB.Text = Format(ActiveCell.Offset(0, 3).Text, "dd/mm/yyyy")

Text would place the date as displayed in the cell.

demo'd from the immediate window:

Activecell.NumberFormat = "mmm dd, yyyy"
? activeCell.Text
Jan 15, 2006
? activeCell.Value
01/15/2006


if you insist on using format (perhaps you are changing the way it is
displayed), then use
tbDOB.Text = Format(ActiveCell.Offset(0, 3).Value, "dd/mm/yyyy")

Avoid using strings to represent dates. Use a date variable or a date serial
number. Use Cdate to convert a string to a date/date serial.

Tom,

Once again many thanks. Too much "give it a try" coding. Have taken out all
coding that refers to FORMAT and now all appears OK.

Now l need a beer........................
