you need to look at the source page of the website to find the correct names for the text input of that page

you can try this where wb is the name of your webbrowser control
vb Code:
  1. wb.navigate2 "http://dms.telenor.com.pk/sca_tp/login.jsp?"
  2. Do Until wb.readystate = 4
  3. DoEvents
  4. Loop
  5. Set f = wb.document.forms(0)
  6. f.all("msisdn").Value = "1235"
  7. f.submit
tested works, change the literal value (1235) for your textbox
f.all("msisdn").Value = text1.text
