I want to catch events between subforms whenever I changed data on the first form and click on the second form.
I'm on the main form. The main form consists of two subforms. I want to catch the editing of records on both. Let's say I changed data on the first subform and then I went to the next subform. I used LostFocus, DeActivate, Exit events but its not cathing the procedure for confirming the update. Only the AfterUpdate event catches them all. The problem is I have to do it two times to get out of the loop to go to the next subform.
On the first subform, there is a form's BeforeUpdate on all controls that if it is not equal to the OldValue property it will change a variable to true.
Dim C As Control
For Each C In Me.Controls
Select Case C.ControlType
Case acTextBox, acComboBox, acListBox, acOptionGroup, acCheckBox
If C.Value <> C.OldValue Then
UpdateDone = True
End If
End Select
Next C
And now I'm trying to catch that by placing this code on the this subform's LostFocus and DeActivate but only works on AfterUpdate event and it prompts again after I select "No"
If ChangedData = True Then
ChangedData = False
Dim ans As Integer
ans = MsgBox("A record has been changed." & vbCrLf & vbCrLf & _
"Do you want to save it?", vbYesNo + vbQuestion, "Changed Records.")
If ans = vbYes Then
Me.Parent.txtAb out_UpdatedBy = fOSUserName
Else
DoCmd.DoMenuIte m acFormBar, acEditMenu, acUndo, , acMenuVer70
End If
End If

Hi,
Why do not try to add this code to each subform before update event?
And not for the totality of the form!
If it is for the totality you can't undo when there is multi records in the subform!
Have a nice day!

gazelle04 Thank you!
Your thread about tracking changes and making undo of records was very usefull for me! :)
In fact i've seen for the first time the use of oldvalue property in before update event!
And I've used today! It does amazing job! And opens a lot my hands to do what I want! :)
Thank you!
:)

Gday everyone,
I'm dearly hoping Stephen Lebans is going to update his masterpeice to
stop the mouse wheel scrolling to work on subforms *he has indicated
this to me but of course beggers can't be choosers here so I have no
idea when this would be done*. I'm just wondering if anyone has gotten
around the problem some other way?

Hi,
I have a form that is designed as a data sheet view. Attached to this
is a subform with some VB code. When the user clicks on a row, the
subform should pop up and run the VB code which accesses the record
corresponding to the row clicked.
To get this row, I tried using Me.Parent.Bookmark. Unfortunately,
this gets the "Current Record" which is set via the navigation

I have a popup "Tools" form with a tab control that has a different subform
on each tab. The problem is that new tabs/subforms continue to be added as
users request new features - so the code on each subform's
Form_Open/Load/Current event fires whenever the popup form is opened, making
the popup form slow to open and causing problems when a function in one
subform is dependent on data or events in another subform (on a different
tab).

Now this is bugging me.
I just released software for a client and they have reported an unhandled

My first concern is that the entirity of the UI and any threaded operations
are all within Try Catches to help me locate the problem and the origination
of any problem by specifiying an error code in the "Catch" section.
So theoretically this shouldn't have been possible (at which point we all

Trying to get back into .net again after being out of it for a while.
I'm trying to figure out the proper way to handle multiple events via a try

What I'm confused about is the proper method to handle, say, 3 separate
events: A, B, and C. I only want all 3 to execute if all 3 can successfully
execute.
Is that what a try-catch is for, or is a try/catch mainly for individual

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
