Hello every one
I need your help please talents
I have ms vb 2012

Lets say i need to make a simple project that i need to update data in a text file

lets say in the project i have
textfiled 1
testfiled 2
textfiled 3
and a botton called update

when i push text in the textfiles and press update , i need the external textfile.txt to be updated with the new values each value in a separate line
but also i need the data to be like this way
for example for textfiled 1 to write data to the textfile like this (fixed text like " &t1=" ) then the text written in the textfiled 1
so the final data that will be updated in the text file will be like this way :
&t1=text from textfiled 1

thanks a lot
