Can expressions be stored in a table and then displayed on a form in a textbox?

Moss100 · Dec 8, 2015

Hello,

I would like to store some default text in a settings table.

For example I would store: ="Hello" & [FirstName] & " " & "[LastName]"

I was hoping when the record was displayed in a textbox on a form it would give me the result: Hello John Smith

Unfortunately it just shows the value: "Hello" & [FirstName] & " " & "[LastName]"

Is there anyway around this?

Many thanks Mark

Where is [FirstName] & [LastName] coming from?

How are you transforming the placeholders into the values you require?

Why aren't you making the value of the form field your concatenation?

Or you could make the column in the table computed

I do not understand why you would do this, but it is possible to run a different calculated control value for each record. So imagine I had a table with a field that contained a field called strCode. It would look like this

Code:

[tt]
ID	strCode
1	=Now()
2	=Date()
3	="The ID is: " & [ID]
4	="Today is: " & Format(date(),"dddd")
[/tt]

Then on the form I have an unbound textbox called txtbxunbound
On the form's current event I have

Code:

Private Sub Form_Current()
  If Not Me.NewRecord Then
    Me.txtBxUnbound.ControlSource = Me.strCode
  End If
End Sub

For each record it shows a different calcuated value from a different expression.

Makes no sense to me, but could be done.

I can't imagine why you'd want to do this - it feels like very bad-practice.

However, take the double quotes off "[Lastname]" and save that to a record, assign that record field content as the text box ControlSource - it should work as you intend.

E.g. store EXACTLY this:

Code:

="Hello " & [FirstName] & " " & [LastName]

N.B. I've added a space at the end of 'Hello'.
