Message box Code

[Tony Williams]

I have a message box which pops up a message after a check on a total. The
code on the Before Update Event is:
If ([txtDomfacsole] + [txtDomfacpart]) <> [txtDomfactot] Then
MsgBox "Row 1 does not add up" & vbCrLf & "It should be " & [txtDomfacsole]
+ [txtDomfacpart], vbOKCancel, "Calculation Error"
Cancel = True
End If
First Question
However I want the user to be able to accept the error if they wish, at the
moment this code keeps appearing as the user tabs to the next control. How
can I change the code so that the user has the choice as to whether or not
they want to change the data?

Second Question
I have some 14 rows, with totals, on a form where this calculation needs to
check the addition of various controls. I could of course put this code
behind every total but I wondered if there was a way to do this onec using a
module. If so could someone guide thru the creation of the module and what I
would have to put behind each total control.

TIA

You need to use a Yes/No message box and tell the app to cancel the
transaction if the 'No' button is pressed:

If ([txtDomfacsole] + [txtDomfacpart]) <> [txtDomfactot] Then

If MsgBox("Row 1 does not add up" & vbCrLf & "It should be " &
[txtDomfacsole] + [txtDomfacpart] & " - Do you want to accept the
error?", vbYesNo, "Calculation Error") = vbNo Then Cancel = True

End If

The user can then use the ESC key to roll back the change(s) and correct
the entries. Question: why not use a query to do the calculations for
you so no calculation checking is needed?

If you create a module then you won't have the luxury of the "Me"
keyword. Create a sub-routine in the form's code and call it from your
controls, eg:

Sub MyCalc()

End Sub

Thanks Keith. The first part works just fine. The reason I'm not using a
query for the calculation is because the users are keying in data from a
form that has been sent to them by outside organisations and they are
checking the data that has been submitted.
I'm not sure I understand the second part could you elaborate?
Thanks again

Hi Tony, glad the first bit worked for you.

A sub-routine is a sequence of VBA code contained within an object such
as a form. The sub-routine is defined by "Sub" and the name you give it
followed by "()" and the "End Sub" statement. A simple example: if you
wanted all the text boxes on your form to cause the computer to beep and
then display a message box before they are updated, your sub-routine
might look like this:

Sub BeepMessage()

Beep
MsgBox("Data will now be updated.", vbOKOnly, "Data update"

End Sub

You would call the sub-routine from one of the controls' events, eg
'Before update':

Private Sub txtMyTextBox_BeforeUpdate(Cancel As Integer)

BeepMessage

End Sub

Not sure off the top of my head how to use a sub-routine to cancel an
event but I'll do a little digging and come back later.

Keith.

Looks like you'd need to use a function, not a sub:

Function MyCancel() As Boolean

Beep
If MsgBox("Are you sure you want to update the data?", vbYesNo, "Confirm
update") = vbNo Then MyCancel = True

End Function

The function returns "True" if the 'No' button is pressed.
You'd then call the function from your Before Update events:

Private Sub txtMyTextBox_BeforeUpdate(Cancel As Integer)

If MyCancel Then Cancel = True

End Sub

If 'MyCancel' returns 'True' then the event is cancelled. There may be a
more elegant way to do this, I'm sure someone will post it if there is ;-)

Thanks Keith I'll have a play around with that.

One thought Keith each of the 14 rows have different control names in other
words it's the same type of calculation but different control names eg
control1+control2=control3
control4+control5=control6
and so on
How would I alter the formula from the first part of my question to use that
in a function to check all rows as they were entered?
Thanks

You'd have to pass the control names to the function as arguments:

Private Sub txtMyTextBox_BeforeUpdate(Cancel As Integer)

If MyCancel(Me.control1,Me.control2,Me.control3) Then Cancel = True

End Sub

Customise the above for whatever the control names are.

Function MyCancel(MyText1, MyText2, MyText3) As Boolean

If (MyText1 + MyText2) <> MyText3 Then

Beep
If MsgBox("Row 1 does not add up" & vbCrLf _
& "It should be " & MyText1 + MyText2 _
& " - Do you want to accept the error?", _
vbYesNo, "Calculation Error") = vbNo Then MyCancel = True

End If

End Function
