Whether the macro results will be shown in real time rather depends on the macro code and what it is supposed to do. For example, add a DocVariable field to the document

{ DOCVARIABLE "varText" }

Create a macro

Sub Test1()
Dim oFld As Field
ActiveDocument.Variables("varText").Value = "This is text"
For Each oFld In ActiveDocument.Fields
If oFld.Type = wdFieldDocVariable Then
If InStr(1, oFld.Code.Text, "varText") > 0 Then oFld.Update
Exit For
End If
Next oFld
End Sub

and run that from a button on the userform


Private Sub CommandButton2_Click()
Call Test1
End Sub

The docvariable field will be updated in real time.

Similarly you can add the content of a text box to a docvariable and associated field

Private Sub TextBox1_Change()
Dim oFld As Field
ActiveDocument.Variables("varTextBox1").Value = TextBox1.Text
For Each oFld In ActiveDocument.Fields
If oFld.Type = wdFieldDocVariable Then
If InStr(1, oFld.Code.Text, "varTextBox1") > 0 Then oFld.Update
Exit For
End If
Next oFld
End Sub
