pdf and visual basic

I am looking for either a Visual Basic function or control that will allow me to edit the forms in a pdf file. Basically, i would like to fill out of the form fields from my Visual Basic program before displaying the pdf. I am also happy with a function or control that will allow me to create a pdf that has form fields where the user can fill some of the fields out later on his/her screen before printing. Note: This is NOT vb.net but the version before.
