Update result of formula in text box - ms-access

I'm trying to update an unbound text box in a form I'm building.
The text box has a default value which is: =DLookUp("[Metadata]![Username]";"[Metadata]").
When the value in the field username is changed;
how do I update this change in the text box without closing the whole form and then opening it again?
--
I've tried to to do this by adding a button in the form and then on mouse up event try and either by vba or the macro editor find a solution.
It would supposedly be possible to create a macro that will close and then open the form again but it's not really what I'm looking for.
VBA: I found lots of suggestions for requery but I couldn't get this to work:
Set UserName = Forms![Update test]!Text10
UserName.Requery
A general solution that could work with multiple such text boxes is preferable
(but not required, anything that tries to point me in the right direction is welcome).

Go to the design view and select the textbox which represents your table value username, then go to events and select the On Change() event:
Private Sub username_Change()
YourTextbox.Value =DLookUp("[Metadata]![Username]";"[Metadata]")
End Sub

How to pass value from subform to mainform ms access

I have a form with a subform (Datasheet view form). When i click a row in subform, i want pass that row value to text box in main form . In subform even wrote this
Private Sub Form_Click()
MsgBox (Noloan)
End Sub
But i don't know how to pass that subform form_click no_loan to mainform.textbox. Thanks for your help.
Additional data:In my db , i have a table which consist field No,NoLoan,Name. NoLoan Field value as i wanna clicked .From that table i create a subform/datasheet view ,subform name is T_Loan1. Then I create Main Form, name is FindLoan2. In that main/parent form i create text box, called Text7, and put T_Loan1 in subform object at footer.
I put this
=[Forms]![FindLoan2]![subformTLOAN].[Form]![Noloan]
in my Text7 Control and It's work.
Thank's for all attention.
Goto to the subform and click on the field which has the row value
Select Field property - click on events tab --> On Click --> Code Builder
Put below code in the Click event where Form_frmMain is your form name and Me.ID is the field.
Private Sub ID_Click()
Forms!FindLoan2.Text7 = Me.ID
End Sub
The best way is to write code that ignores the forms!names. If you copy the form, or change the sub form, or even drop the sub form into a different form, then all your code breaks.
To reference the textbox in the parent form from code, use:
me.Parent!Text7 = me!id
I am not sure which version of MS Access you are using, but it is also possible to use Tempvars to store values for use elsewhere if you have a complicated application which makes referencing another form/field/control difficult.
To create:
Tempvars.Add "TempVarName", TempvarValue
To use:
Tempvars!TempVarName
To remove:
Tempvars.Remove "TempVarName
I try to limit my use of them, as it becomes hard to manage. I am always careful about when I set the values and I ensure that they are removed after I am finished with them to avoid confusion or issues with values persisting when they shouldn't.

Paste a value in a textbox on the second tab of a navigation form access vba

I'm quite new to VBA and I've been looking around but cannot seem to find a solution to my problem.
I have made a navigation form (frmNavigation) with 3 buttons, each referring to a different form, let's call them frm1, frm2 and frm3. In the navigationform the control buttons to switch between tabs are all named differently (btn1, btn2, btn3), but the subform that shows either frm1, frm2, or frm3 has the same name: “NavigationSubform” (this shows a different form depending on which tab is clicked on, based on the 'navagation target name' referring to frm1, frm2 and frm3).
When I want to refer to a textbox (txtBox1) on form 1 (first tab) and insert a value i can do this by:
Forms!frmNavigation!NavigationSubform.Form!txtBox1.Value = "insert awesome text"
But how would I refer to txtbox10 on the second tab (frm2)? Just using the following does not work:
Forms!frmNavigation!NavigationSubform.Form!txtBox10.Value
You then get the error 2465 (can't find the field).
I’ve been trying many different things, but can’t seem to get it right. So how do I refer to a textbox on a different tab than the first one?
Help us much appreciated!
Only one subform can be loaded at once. So you've just got to break this process into two steps.
Store the value from txtBox1 somewhere outside of the NavigationSubforms (a textbox on the parent form with visible = no, a global variable or a table works).
In frm2's On Load event, set txtbox10 to be the value you stored.
Just note, that you will need to add conditions in the On Load event if you want to avoid that textbox being set to an empty string or a wrong value if you have a setup where your filter is changing.

Populate textboxes with value from listbox selection on child form

I realise this question has been asked before and I have tried numerous suggestions, but I guess I am just too much of a novice when it comes to VBA coding.
Here is my scenario:
I have an Access 2007 "Application" with a few forms. On the main form, I have 2 text boxes. For simplicity let's call them textbox1 and textbox2.
textbox1 is used to enter a style code. a button on the main form then opens another in modal/dialog mode and runs a query with the style code as the where clasue. the modal popup gives me a list box which is populated from the database based on the query that was passed. I then need to select one of the products in the list and upon closing the popup, populate textbox2 with the brand (column2 in the list from the popup) number.
Please remember that I am a novice. Any help would be greatly appreciated.
I would put a button on the second form, and in the _Click() function, put something like this
If ListBox1.ListIndex = -1 Then
MsgBox "Nothing Selected!"
Exit Sub
End If
UserForm1.TextBox1.Text = ListBox1.List(ListBox1.ListIndex)
Unload Me
Where ListBox1 is the list box containing the content you need the user to select from, where UserForm1 is the name of the calling form, and TextBox1 is the name.
Explanation
The ListIndex property of the list box returns the index of the selected list item. If nothing is selected, it returns a -1.
To reference an item on one from from another, you reference the form, the object and the property.
In The example I gave, the form is UserForm1, the object is TextBox1 and the Property is Text. While typing, intellisense should auto complete the object and properties once you type the period.

Opening a combo box from another object

I would like to know if it is possible to open a combo box and see it's elements listed from another object on the form. I do not like the 'down arrow' on the combo box and would like to create something more 'stylish' if it is possible. I am wondering if there is a routine one could write and put on another object so that upon the 'on click' event, the user will see all the elements listed within the combo box and have the opportunity to select one of them.
For that you can use the Dropdown method of Combobox object.
Example:
Dim cmb1 As ComboBox: Set cmb1 = Me.Combo1
cmb1.SetFocus ' necessary
cmb1.Dropdown
Note: The control needs to have focus so you have to set it programmatically first.

MS Access de-select listbox after running macro/query

So I have a form (frmBookingForm) in Access, and a listbox (lstMyBookings) that displays the results of a query.
Below this, I have a button (cmdDeleteBooking) which runs a delete query using the lstMyBookings selection as input. The button then runs a macro that firstly checks whether a record in the listbox is selected, and if one is, runs the delete query and requeries the data, so the deleted record is no longer shown in the listbox. If not, an error message is displayed.
However, if I then click the button again, it again runs the delete query, even though there is apparently nothing selected in the list box.
Essentially, how can I 'clear' the listbox selection?
I'd prefer a solution that can be done in a macro format, as I have little to no understanding of VBA. However, if providing a VBA solution, I'd greatly appreciate a short explanation of it.
Thanks :)
Looks like this website has a nice little function to do it. Essentially, you need to test if it's a multiselect, and then do one of two things. I suppose if you know ahead of time that it is/isn't a multiselect, you wouldn't even need the "if" statement:
If List0.MultiSelect = 0 Then
List0 = Null
Else
For Each varItem In List0.ItemsSelected
List0.Selected(varItem) = False
Next
End If
If the control's MultiSelect property is set to None, this code just sets List0 to Null. If the control's MultiSelect property is set to anything else, the code loops through all items that are currently selected, and sets the Selected property of that item to False. My example assumes your control is called List0.
EDIT
To use this code, use an event instead of a macro. Here's how you do this:
Right click on the button, select properties
In the Property Sheet window, click on the "Event" tab
Click inside of the "On Click" blank area, and click the dropdown arrow, then select "[Event Procedure]"
Click the ellipsis ("...") to go into the code editor.
In the code editor, your should already have your event for the button (let's assume the button is called Command1:
Private Sub Command1_Click()
End Sub
Add your code in between (assuming the listbox is called List0):
Private Sub Command1_Click()
If List0.MultiSelect = 0 Then
List0 = Null
Else
For Each varItem In List0.ItemsSelected
List0.Selected(varItem) = False
Next
End If
End Sub
