I am trying to get an understanding of what the syntax would be to access a specific field within a query that makes up a subform within another form.
Form > SubForm/Query > Field
The field I am trying to get access to a field called Berthed that operates as a Boolean field. Either the vessel is present or it is absent.
This is what I was trying and it does not work.
Me.Boat_Move_Prior_Week.SourceObject.berthed
In this case here is the breakdown
Me = current form
Boat_Move_Prior_Week = query
Berthed = field I am trying to access through the VBA
My final goal will be to create an If statement, that upon requery of the Form, will look at the Berthed field, and if the field is checked (vessel is present) do nothing, but if the field is unchecked (vessel is not present) then remove the vessel from the query.
To reach the field (on the subform) bound to the field berthed, this is the syntax (assuming the textbox on the subform also is named berthed):
IsBerthed = Me!NameOfSubformControl.Form!berthed.Value
Here an amazing guide to know how to deal with controls in main form and subforms:

Aside from my syntax issues I should have been using False for the value. Thanks to the two posters above for getting me in the right direction.
If Me.Boat_Move_Prior_Week.Form!BERTHED.value = False Then
Me.Boat_Move_Prior_Week.SourceObject = ""
End If

Error popup after click ok on type mismatch
I am using a combo box to search for records and it is telling me I have a type mismatch. I have been unable to find where this mismatch would be. The combo box still performs the desired function of selecting all records based on their "region"
I am using an ID field which is selected using the combo box but I want to pull through a name as well so I have input an unbound textbox and used VBA on change in the ID to update the name to the corresponding ID in the unbound textbox
Form
For privacy reasons I snipped around some of the other fields showing data.
The VBA in the on_change event in ID goes
Private Sub txtSupplierID_Change()
Me.txtSupplerName.Value = Table("tblSuppliers").SupplierName
Where Table("tblSuppliers").ID = txtSupplierID
End Sub
I'm aware this code could be very wrong but I could not find anywhere else that showed me how to do what I was trying to do. Any suggestions on how to actually do it would be appreciated. If I have not been as detailed as needed or yo have any questions please ask.
Edit for Clarification:
The form is not being used to save data. It is only being used to display data and issue an output to a report.
Code is not just wrong, it is nonsense. Cannot reference a table object like that. And that Where usage is not valid. One way to pull value from a table is with DLookup domain aggregate function. Advise use AfterUpdate instead of Change event.
Private Sub txtSupplierID_AfterUpdate()
Me.txtSupplerName.Value = DLookup("SupplierName", "tblSuppliers", "ID = " & txtSupplierID)
End Sub
Might want to correct textbox name from txtSupplerName to txtSupplierName.
However, should not save both supplier ID and supplier name into this table. There really should be no need for this VBA. Just put DLookup() expression in a textbox ControlSource. For other methods of pulling the supplier name to form, review answer in MS Access Identical Comboboxes for Autofill
I have the following pair of combobox that are used for two inserts in two different access tables from a single form.
The problem I have is that I am not able to make anything else load the form is selected both in Name_OT and in Year the first value that contains corresponding combobox.
I think the solution is with:
Combobox1.Selected (0) = True 'First value
But the combobox goes blank, no text or anything appears.
Solved with this
Cuadro_combinado79 = Cuadro_combinado79.ItemData(0)
Cuadro_combinado85 = Cuadro_combinado85.ItemData(0)
I am relatively new to Access and any SQL and VBA I have picked up is self-taught, so I would really appreciate answers that are not too heavily laden with technical terms...that said, I am having an issue with allowing comboboxes to be left blank on a form if the user chooses not to input data. Also, I am using Access 2016.
Initially the problem I ran into was that if a combobox was entirely skipped and left blank, or if the user selects the combobox and then tries to move on without making a selection from the list, they got the error "You tried to assign the Null value to a variable that is not a Variant data type," and were unable to move on to any other fields on the form or to save the record being entered.
I found this article that details a possible solution, but I can't seem to get it to work. I made an unbound combobox, set the Row Source to:
SELECT EmailID, PersonalEmail FROM EmailT UNION SELECT "<N/A>","<N/A>" FROM EmailT
ORDER BY PersonalEmail;
where PersonalEmail is a field of type short text and the EmailID is an autonumber. I also followed the article's steps for formatting the combobox (column width, etc.) and set it to Limit to List = Yes.
Here is my exact code:
Private Sub Combo62_AfterUpdate()
If Combo62 = "<N/A>" Then
EmailID = Null
Else
EmailID = Combo62
End If
End Sub
Private Sub Form_Current()
If IsNull(EmailID) Then
Combo62 = "<N/A>"
Else
Combo62 = EmailID
End If
End Sub
< N/A> now shows up on my list, but if it is selected I get the error: "The value you entered isn't valid for this field. For example, you may have entered text in a numeric field or a number that is larger than the FieldSize setting permits."
Access's debugger highlights the line:
EmailID = Null
but I am not sure what steps I should take now to try and fix this.
I am completely open to other methods of allowing the combobox to be left blank if someone knows of a better way to do this also. For all I know, I am missing something really obvious! Thanks in advance for any insight!
EDIT: Thanks for your help guys, I never did figure out what exactly the problem was, but I got some advice from another forum to rethink my database design so this ended up being a null issue--it's all totally different now!
If the recordsource for your form contains a query with one-to-many relationships this error may come up. Try to use only the base table as the recordsource for the form. Use subforms if you need to display related data. The rest of the code may then be unnecessary.
I currently have a form. The form contains a subform that displays a Query. The Form also has 2 Text Boxes and buttons for both Boxes. The first box acts as a filter for the query to filter specific record. The second box is intended to be used to hide columns in the query. My issue is that my code will not recognize the text box, or any outside source from my form as a Field Name to be found. Here is my current code:
Private Sub Command137_Click()
Forms![Vermont]![Query1 subform].Form.[Query1 Field Name].ColumnHidden = True
End Sub
Currently if I replace "Query1 Field Name" with any field name that exists in the query the column will hide. However if replaced with anything else I recieve the following error:
"Runtime Error '2465'
Microsoft Access Can't Find the Field '|' reffered to in your expression"
I am pretty sure that I am not referencing the Form Control correctly. I have tried replacing [Query1 Field Name] with the following:
[Text142.Text]
[=Text142]
[Text142]
[Forms![Vermont]![Text142]]
I am very new to VBA but I definitely feel as if this is an easy fix; if possible.
Thank you in advance for any help!
Subform references are always a bit weird. This should work, though:
Forms![Vermont]![Query1 subform]![Text142].ColumnHidden = True
Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records.
Here is the line that opens the form:
DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery
Before the line is ran, strQuery equals:
1=1 AND [NCMR].[NCMR_NUM] = '12-129'
The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition.
DCount("[NCMR_NUM]", "NCMR", strQuery)
Check your form's Data Entry property. You can find it on the Data tab of the form's property sheet.
If Data Entry = Yes, the form will not display existing records.
Sounds like you want Data Entry = No, so that existing records which match your OpenForm WhereCondition will be displayed.
