How to enter multiple string variables into a text box - vba

Question

I have a workbook with an userform that captures user input into string and single variables and I want to display a text consisting those variables into a text box on the same userform using new line and tab.
Example:
Dim dog as String 'rex
Dim years as Single '5
Dim owner As String 'Joe
Dim address as String '123 Sample Street
Dim value as Single '300.00
I would like to have a textbox on my form, that would display:
The dog's name is rex. He is 5 years old.
Owner: Joe
Address: 123 Sample Street
Treatment value: 300.00
I used
textbox.value = "The dog's name is " & dog & vbNewLine & vbNewLine & "Owner: " & owner & vbNewLine & "Address: " & address & vbNewLine & vbNewLine & "Treatment value: " & value
But after some time i will not be able to add another character to this line and I have plenty more variables mixed with text to come.
Can you suggest how this can be done?
Update: Resolved
Many thanks for your help.

Answer 1

Try
textbox.value = "The dog's name is " & dog & vbNewLine & vbNewLine
textbox.value = textbox.value & "Owner: " & owner & vbNewLine
textbox.value = textbox.value & "Treatment value: " & value & vbNewLine
Continue with other fields!

Answer 2

Try like this:
textbox.value = "The dog's name is " & dog & vbNewLine & vbNewLine & _
"Owner: " & owner & vbNewLine & _
"Address: " & address & vbNewLine & vbNewLine _
& "Treatment value: " & value
The " _" signs help you break the code into more lines. Note, that we have 2 signs - space and underscore there.
A small info - it is possibly good to consider passing the text as a .Text and not as .Value. Here is something good to read - Distinction between using .text and .value in VBA Access
