Subform not linking to Main form

2 New Member
Hello,

I have 2 subforms in a Main form, one links fine, the other doesn't. I am trying to link them both to a "tracking ID" on the main form. The Tracking ID is a text field that is a combination of an auto-number and an Alpha expression. The subform that links fine is a comments form (continuous form with just date field and memo box) and the subform that won't link is a larger, more detailed form where I would like to add more than one "Action Plan" to the item on the main form. The parent/child relationships on both are tracking ID to tracking ID. They are also linked by tracking ID in relationships. I didn't do anything different with the Action Plan form as opposed to the Comments form except the continuous form part, so I can't figure out why one works and the other doesn't. I've tried to make it a continuous form, too, and it still doesn't work.

My primary keys are auto-numbers in each table and I just added a tracking ID field to each table for linking purposes.

I have checked it over and over and can't see anything I'm missing, but can't figure out why the information in the Action Plan form will not show up in it's appropriate Tracking record??? Maybe I'm missing something???

try to remove that subform and readd it using the access wizard so that we can know what is causing the error. access wizards usually tells you if something is wrong with your setup.

sorry, that is all i have to say right now. :)

So you have your subform based on a query, or a table?

Query would be far more flexible, allows to enter the criteria you want in the query design view: i.e. =Forms![YourMainForm].[TrackingIDContr olName]

This will then tell the query to display the records you want to see.

Then all you need is a Forms![YourMainForm]![YourSubForm].Form.Requery command in the afterupdate event of your TrackingID control to requery the subform and thereby show the appropriate records.

Regards,
Scott

Access 2000- my form has fields for “name”, “arrival”, “departure” and “site nbr”. Can I make a subform under “name” that keeps a history of all previous entries to arrival/departure/site nbr so that when the main form is changed, the new information is ADDED to the subform?

Hi, I have two very similar forms each with a subform. The main form gets a few fields from the user and passes this back to a query that the subform is bound to. The requery is done when the user enters the last qualifying field on the main form. In one case this works fine, the subform shows the data the user wants to update -- which means showing all the data put in previously (ie showing this via the requery and the continuous...

Greetings all, I have a main form (frmClients) with two subforms (subVisits) (subAccount). I got the subforms to reflect what the main form is showing by linking master and child fields (I think--newbie here). Now I need the second subform (subAccount) to update when I add a visit in the subVisits subform. I assume that the AfterUpdate would do it, but I cant figure out what the code is to update another subform would be. Not...

I am using the following code in my TabControl to manage subform loads. The code assigns the subForms SourceObject. - Do I also need code to DeAssign the SourceObject when leaving the Tab, I'm thinking the Table will stay open otherwise ??? - Do I also need to use code to Assign the Child&Master Links, or can I just type the names into the subForms Control Property and just depend on the SourceObject to link to Table???

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.
