I have solved
I read the file as a text and i replace the value before load the page as loadhtml
in the html page i have insered a placeholder for the 2 value that i need to change
example:
<gaugetitle> and <gaugevalue>

replace value in html page:

Dim pagehtml as String
Dim title as String
Dim value as Int
pagehtml = File.ReadString(File.Dirassets,"gauge.html").replace("<gaugetitle>",title).replace("<gaugevalue>",value)

WebWiew1.loadhtml(pagehtml)

if anyone have different solution, please tell me

You should start a new thread for yany new problem/question you have.

Posting multiple questions in the same thread is a mistake; one Thread should summarize one question.
