pass value within one form in ms-access - vba

hey i am a total noob and only found ways to pass a value between two forms.
this is the form i am working with: form.
in this form (event.form) there is a subform (Fundort_kurz-Subform) which lists data. when i click one row inside the subform the value for "objid" appears in textbox "text501" by "=[Fundort_kurz-Subform].[Form]![Objid]". I automatically want the value from field "text501" to be passed to field "Objid_3" which is meant to write the value into the table.

Not sure what you are doing, but use the OnCurrent event of the subform:
Me.Parent!Objid_3.Value = Me!text501.Value
And do rename your controls to something meaningful.

How to Update the Values of a Dropdown in a Subform when the Main Form Changes

I have two forms:
InterviewMaster and InterviewDetail
InterviewDetail opens up as a subform in InterviewMaster and these two forms are linked through a common field called InterviewID
In InterviewDetail I have a textbox called Questiontype as well as combobox called InterviewDropdown.
The data in the dropdown varies based on the data on in the textbox. To make this happen, I have a next button to move to the next question. Whenever I click on next the following runs:
Dim ctlCombo As Control
Set ctlCombo = Forms!InterviewDetail!cmbInterviewDropdown
ctlCombo.Requery
The Row Source setting for my combobox is set to look up the required answers, again this is based on the value as per the textbox:
SELECT [queryAnswerOptions].[Answer] FROM queryAnswerOptions ORDER BY [Answer];
So the options are determined by my query called queryAnswerOptions
So as I cycle through my questions using my next and previous buttons, the dropdown options are updated based on the value of my textbox. This works perfectly when I open the subform from the navigation pane. However, when I open the main form and click on the next button my dropdown does not have any values. I've tried requerying the subform with no luck. I've also tried opening the subform in full screen from my main form but this also does not work. I also don't want to go that route as it does not work well with the overall flow of my form.
Any assistance will be greatly appreciated.
Problem with the query WHERE criteria parameter is when form is installed as a subform, the form reference no longer works because it must use the subform container control name. I always name container control different from the object it holds, such as ctrDetails.
Option is to put SQL statement directly in combobox RowSource instead of basing combobox RowSource on a dynamic parameterized query object - then it will work whether form is standalone or a subform.
SELECT Answer FROM InterviewAnswers WHERE QuestionID = [txtQuestionID] ORDER BY Answer;

VBA - Filter subform on unbound field in form

I am passing a value from a lookup form to another form. The value shows in an unbound field on the form (works great). I also want the subform to be filtered by what is in this unbound field. So, for example, I pick 2016 on my lookup form. It brings up another form, enters the value 2016 into an unbound field called yearvar. I cannot get it to filter what's in the subform. Here's my code that's not working:
yearvar.Value = Me.OpenArgs 'Enters year from lookup form into field call yearvar
Forms!frmEthEntCatYr.frmEthEntCatSubCatYr.Form.Filter = "[EthYear]= " & Chr(34) & Forms!frmEthEntCatYr.yearvar & Chr(34)
Form name is frmEthEntCatYr. Subform name is frmEthEntCatSubCatYr. Unbound field on form is called Yearvar. Field on subform that I want to filter is called EthYear.
What am I doing wrong? Thanks in advance!
Problem solved and it was an easy fix (thanks to someone helping me with my dah moment). I had originally tried to link the main form and subform using the Subform field linker wizard, but the unbound field was not showing (yearvar) in the Master Fields dropdowns in the Link wizard. Someone suggested just putting it in the Property Sheet - in Link Master fields, I typed yearvar and in Link Child Fields, I typed Ethyear. Works perfectly now. Lesson of the day for me: sometimes the wizards do not do what we want them to do, and you have to do it the manual way. And I didn't even have to write code to do this!

MS Access: text box value show #Name?

I have created a form and set the form's RecordSource to a query. Below is my query:
SELECT GeneralT.*, SalaryT.[Status]
FROM GeneralT INNER JOIN SalaryT ON GeneralT.Deposits = SalaryT.Deposits;
In the form I have 4 textboxes. In the first 3 textboxes I show value from GeneralT table and in fourth textbox I show SalaryT.[Status] value. But this fourth value doesn't show in the textbox rather it show #Name?.
If I open the query in datasheet view I can see all the value properly. I don't understand what is wrong here. Please help me to show the result properly in the form.
Displaying #Name? for a field says that field has a control source that does not match with the query linked to the form. Some things to check:
Make sure Status is a selection from one of the pre-existing options in the Control Source drop down combo box. Click on the combo box to make sure.
Double check to make sure it is a "Text Box" and not a custom
control.
Make sure there isn't another text box named Status
Try chaning the control source to just Status instead of SalaryT.[Status]. If the field name does not conflict with the naming of a field in GeneralT, the selected SalaryT.[Status] will actually be displayed named Status.

MS Access: listbox appears to be locked when assigned to ID's on continous form

I have a continuous form where i have a listbox assigned to an ID. I cant seem to select anything in the list box. I have the row source property set to a Value List. I manually typed in "Y";"N" for the list.
If I don't assign the control source to the ID, all listboxes are selected at once on the form.
Is there any property I should change?
Thanks
You cannot sensibly use unbound controls on a continuous form.

Gray out a form row's (detail's) button conditionally with VBA code

I have a standard form in MS-Access which lists a bunch of orders, and each row contains order no, customer, etc fields + a button to view notes and attached document files.
On request from our customer we should gray out the button btnAnm (or check or uncheck a checkbox) depending on a calculation from two queries to two other tables (a SELECT COUNT WHERE and a check if a text field is empty).
I've tried btnAnm_BeforeUpdate(...) and btnAnm_BeforeRender(...) and put breakpoints in the subs, but none of them trigger. The same if I use the control Ordernr instead of btnAnm.
I'd like a function in the Detail VBA code to be triggered for each "Me." (row) so to speak, and set the row's control's properties in that sub.
What do I do? I've looked at the help file and searched here.
*Edit: So I want to do something that "isn't made to work that way"? Ie. events are not triggered in Details.
As an alternative, could I base the value of a checkbox on each line on a query based on the 'Ordernr' field of the current row and the result of a SELECT COUNT from another table and empty field check?
Do I do this in the query the list is based on, or can I bind the extra checkbox field to a query?
A description of how to do this (combine a COUNT and a WHERE "not empty" to yes/no checkbox value) would be perfectly acceptable, I think! :)*
You cannot do much with an unbound control in a continuous form, anything you do will only apply to the current record. You can use a bound control with a click event so that it acts like a button.
Presumably the related documents have a reference to the order number that appears on your form, which means that you can create a control, let us call it CountOrders, with a ControlSource like so:
=DCount("OrderID","QueryName","OrderID=" & [OrderID])
The control can be hidden, or you can set it up to return true or False for use with a textbox, you can also use it for Conditional Formatting, but sadly, not for command buttons.
Expression Is [CountOrders]>0
You can also hide the contents and add a click event so that is acts in place of the command button. Conditional Formatting will allow you to enable or disable a textbox.
As I understand your question, you have a continuous form with as command button that appears on each row - and you'd like to enable/disable the button conditionally depending on the contents of the row.
Unfortunately you can't do that. It seems that you can't reference the individual command buttons separately.
Having wanted to do something similar in the past I came up with two alternate ways of setting up my interface.
Put a trap into the onClick code for the Button. Which is icky, because it is counter intuitive to the user. But it gets you that functionality now.
Move the command button (and editable fields) up into the form header, and make the rows read only. Your users then interact with the record only in the header, and select the record they want work with in the list below. As I recall this is known a Master-Detail interface.
