how to clear text box inside a macro? - ms-access

I have a macro for onclick event for a combo, how do i have something to clear the text box in the same form when the user click on combo box and make selection. I would like to do the clear inside the same macro rather than a procedure.

Not clear what you mean by macro? Do you mean the new macro language in Access, or do you mean VBA code?
In VBA code you can just go:
Me.MyComboBox = null
In macro code, you use SetProperty, input the name of your Control, set the Property to "Value" and just leave the Value blank.

Update result of formula in text box

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

Clear out dropdown value once another drodown value is changed in vba access?

I have three combo box controls(MFG, Code, and GrpID) in my VBA access form. Once the user selects an option from the first combo box (MFG), rest of combo boxes give me available options. But I need to do some validation i.e. what if the user decided to change the value of first combo box? The values of rest combo box should be cleared. All I need to do is once the first combo box is changed the second and third combo box need to be cleared out or at least set to focus on them so that users will realize that they can't use old values as first value is cleared in the first combo box. I added a code block 'AfterUpdate for first combo box as shown below:
Private Sub MFG_AfterUpdate()
Code.Value = " "
GrpID.Value = 0
End Sub
The problem after writing above code is: they don't get empty until they(Code and GrpID) get clicked. In other words, I need to click them to empty them every time I change the value of MFG. Can anyone direct me how do I clear them or at least focus them?
Set the combo to null to wipe any displayed value in them;
Me.Code = Null
Me.GrpID = Null
This assumes your combo controls are called the same as your field names.
Edit for clarity: Including the Me. makes sure your are changing the form control values. If your field names are the same as the controls then Access will change the underlying field values, and as you have discovered on your form these aren't reflected until you click in that fields bound control.

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.

copy value entered in unbound textbox to label after pressing button

I have an unbound text box on my form which the admin can enter a date of when records were last updated. I want this date to be copied to a label after pushing a button so that it holds the date instead of it do disappear after closing the form.
does anyone know if this is possible and how it is possible?
For creating a variable that can be used AFTER the form is closed:
Create a new module (in code window, click 'Insert | Module'
Insert the variable name(s) and types you want available everywhere. i.e.
Global dtLastUpdated As Date
Global strSaveSomeName As String
Save the module as mdl_Globals
Add code wherever needed to set the variable, then can reference anywhere.
If for use during the form, use the following: where 'lblForUnbound' is the Label field and 'txtUnbound' is your unbound text box
Me.lblForUnbound.Caption = Me.txtUnbound.Text
