Hello,
I am trying to get a date field to autofill based on the date of another date field. I want the autofilled date to be 30 days after the other date. For example, if the user has entered 06/15 in the first date field, I want the second field to automatically populate with 7/15. I have tried everything I can think of to no avail! I can't imagine this is a difficult thing to do........
Anyone have any ideas?

Assuming your 2 Date Fields are [Date1] and [Date2], in the AfterUpdate() Event of [Date1], place the following code. When finished, it should look like: - Private Sub Date1_AfterUpdate()
-
'Is there a Value in [Date1] AND is it a Valid Date?
-
If Not IsNull(Me![Date1]) And IsDate(Me![Date1]) Then
-
Me![Date2] = DateAdd("d", 30, Me![Date1])
-
End If
-
End Sub

In the after update event of datefield1 put the following code ... -
Me!datefield2 = DateAdd("d", 30, Me!datefield1)

Thanks ADezii!
I was trying something close to that, but apparently ooooh soooo far off!!! :)

The answer depends on how you intend to use this field to my mind. If you're entering new data then it's probably better to set the .DelaultValue property of the control. If it's simply for display, then set the .ControlSource to : - =IIf([DateField1] Is Null,Null,DateAdd('d',30,[DateField1]))
@NeoPa
NeoPA, I see what you were talking about now. The date field is populating on the form, but it not in the table. How do get the date into the table as well?
You don't! Very seldom is there a valid reason to store a calculated value in a table! It wastes storage space, and running a calculation is almost sure to take less time than retrieving a value form the disk.
Instead, you merely re-calculate the value as needed, in a form, report or query.

Not sure if this will help but I had a similar issue and this is what I did....
ACTION DESIRED: Have one date field trigger (calculate) future or past date values in other date fields in a form and (Most importantly)hav e those values save in the master database table and queries.
TRIGGER FIELD: Re Insp Date
AFFECTED CALCULATED FIELDS: Re Insp Date 90 Day (To be set to -90 from "Re Insp Date") Re Insp Date 60 Day (To be set to -60 from "Re Insp Date") Re Insp Date 30 Day (To be set to -30 from "Re Insp Date")
SOLUTION: Opened up the properties of what is to be the "trigger" date field went to 'All' tab Opened up a 'Code Builder' Event Procedure in the "After Update" property Entered the following VBA code - Private Sub Re_Insp_Date_AfterUpdate()
-
Re_Insp_Date_90_Day = Re_Insp_Date - 90
-
Re_Insp_Date_60_Day = Re_Insp_Date - 60
-
Re_Insp_Date_30_Day = Re_Insp_Date - 30
-
-
End Sub
NOTE: If there are spaces in the name fields, an underscore has to replace the spaces. As shown in the VBA code above, "Re Insp Date" field name must be coded as "Re_Insp_Da te". (This is why many suggest you use no spacing in when naming database fields, tables, queries, forms, objects, etc)
Hopefully this helps someone else in the future.
Anyway, there it is.

I have a search form with a query-linked subform.
One of the fields in the subform are date fields.
Is there a way to autopopulate the DateFilled field when the person
enters the field? I need this to be code which is entered into the
form, rather than as a property of the field in the table because
there is other data which is entered before. This data is entered in
at a later date.

Hi,
I have some comboboxes that are created dynamically at run time based
on user actions. I found a procedure on a message board to autofill
the combobox text from the dataview that the comboboxes are bound to.
It works perfectly on the comboboxes that I have created at design
time, but the ones that I create runtime behave differently.
The problem is that when the user tabs onto the combobox, the box
stays blank, which is fine. ...
