Loops for Parent/Child relationships

Thank you in advance for all your assistance, it is GREATLY appreciated. I'm
writing a small Access 2000 program for tracking Kennel Litters for a friend
and I'm wondering how I can loop through all records from a Parent form to the
Child form with a matching Parent Child relationship.

What I'm trying to do is make it where she can check a box or hit a command
button, loop through all the child records with the same ParentID as the
foreign ChildID and update Date, Procedure and other various information.

Example: Shot for one dog, will be same for all the dogs in that litter.
Instead of having to enter each shot individually, a checkbox or command button
could be used to enter all similar shots/procedures for the complete litter?

For 'loop through all records' which is a procedural expression,
relational databases use update statements (queries, in Access).

You can create a query that updates a field in every record conforming
to certain criteria. I don't know what a litter is, but if you have an
expression for one litter, you can put that in the criteria row with the
update query.

Play with it, maybe you get the hang of it.

Dim db as database
Dim SQLString as string

Set db=CurrentDB
SQLString = "UPDATE ChildRecord SET ChildRecord.Sho tDate = #" &
Me!DateOfShot & #"
SQLString = SQLString & " WHERE ChildRecord.Par entID= " & Me!ParentID & ";"
DB.Execute SQLString

This is air code.

Will you always perform the same procedure on all members of the litter? For
some procedures I would agree but for others it may be just a few of the
litter.

I would suggest an approach that would allow you to update one, more than one
or all child records with the same procedures by selecting child records. You
could provide the means to select all records by using a command button for the
list of child records or select each record that needs to be updated. Then
process only the records that were "selected" for processing.

Sorry to bother you guys but I have another questions related to DataSets. I'm almost there now, so I dont expect to bug you much more ( Hopefully ). I have Master / Details tables with cascading relationships between them. When I Update the master using the DataAdapter we get a new ID for the new master row and all the child row foreign keys are updated to the newly aquired ID.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
