How to pass a GUID from record to record in the same form

[James Schoen]

I have created a form that allows users to select a model number using a dropdown and click a button to open a sub-form. When it opens the sub-form, it passes the record id, in this case a GUID successfully. However, when the user enters a serial number on the sub-form and goes to the next record, it doesn't pass the GUID. I have been able to pass a simple text string (text29 - for testing) but just not the GUID.

My reason for this is to allow users to enter multiple serial numbers assigned to the same model number without entering the model number in every time. I am a newbie to VBA and Access. So, any help is greatly appreciated.

My code:
Main Form:
Private Sub Command24_Click()
RunCommand acCmdSaveRecord
DoCmd.OpenForm "addMultipleNewInventory"
Forms!addMultipleNewInventory!partsLookupUUID.Valu e = Me!Combo9.Value
Forms!addMultipleNewInventory!Text29.Value = Me!serialNumber.Value
DoCmd.Close acForm, "Add New Inventory", acSaveYes
End Sub

Sub-Form:
Private Sub Form_AfterUpdate()
Me!partsLookupUUID.Value = Me!partsLookupUUID.Value
Me!Text29.Value = Me!Text29.Value
End Sub

James,
Welcome. I think you'll find this site to be a huge help as you learn your way around Access and VBA.

Here is a page I refer to constantly. It helps me get the syntax right for referring to objects on forms and subforms. http://www.mvps.org/access/forms/frm0031.htm

Here are a few other basic. Change the names of your objects to be meaningful names. Command24 and Text29 do nothing to tell the purpose of those objects. And always put error checking into routines. Perhaps if you do that in this case you'll see where your problem lies. Your error checking will be something like this

On error goto Err_Command24_Click 'put this 1st in the routine
'put the following code at the end of the routine and all other code goes between the above and the below code
 
   On Error GoTo 0
   Exit Function
 
Err_Command24_Click:
 
    MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure GetNewGuid of Class Module Command24_Click"
    Resume Next

End Function

I installed MZ-Tools from http://www.mztools.com/index.aspx. It is a fantastic free tool that puts the error checking in for you automatically with one click.

Now, for your problem, it is not very clear what you are telling about the subform.

It's not clear to me how you expect the information to flow from one form to the other. When your subform is updated there is no useful action taking place. The code

Me!partsLookupUUID.Value = Me!partsLookupUUID.Value
Me!Text29.Value = Me!Text29.Value

doesn't do anything

I can't tell what "Me" is because I don't know what form's AfterUpdate event is being handled. It looks like it is part of form addMultipleNewInventory. If that's so, then you probably want

Forms!mainformname!Combo9.Value = me!partsLookupUUID.Value 
Forms!mainformname!serialNumber.Value = me!Text29.Value 

I'm not sure the subform's afterupdate event is the best place for that; maybe you could put it in the oncurrent event of the subform, so even if you don't update anything, if you're just browsing through the file you'll get the same effect. And also then in the afterupdate event of the the specific text boxes or other fields that might be edited.

Hope that helps,
Jim

Thanks, I will look at it some more tomorrow. I will let you know how it goes. I really appreciate your speedy reply.
