Read Word ActiveX radio button into vb.net form -

i'm working on code read values in word document windows form using vb.net. word document designed data read in contained within content controls. here sample of code:

private sub importwordbutton_click(sender object, e eventargs) handles importwordbutton.click     dim oword microsoft.office.interop.word.application     dim odoc microsoft.office.interop.word.document     dim occ microsoft.office.interop.word.contentcontrol      oword = createobject("word.application")     odoc = oword.documents.open("c:\temp\pifformtest2.docx", [readonly]:=false)      each occ in odoc.contentcontrols         select case occ.tag             case "pifno"                 numberbox.text = occ.range.text             case "piftitle"                 titlebox.text = occ.range.text              case "initiator"                 initiatorbox.text = occ.range.text             case "pthealthsafety"                 healthsafecheckbox.checked = occ.checked             case "ptregenviro"                 regenvcheckbox.checked = occ.checked 

... goes on. of content in word file captured activex radio buttons rather content controls. can't seem find correct object referring radio buttons. i've spent significant time searching web. appreciated.

i'm working on too, , it's nightmare.

for each f field in odoc.fields    'notice fields not content controls     console.writeline(f.oleformat.object.name) 'notice properties, not methods... next 

here's msdn reference
