Update a cell in tables in header in word document using .net

Hello,

I have opened a word document in vb.net. This word document has table in header and in the document. I tried updating a table in document it works fine. But not able to succeed in updating table which is in header. Need help to know the syntax to update the table in header.

'update table
Dim r As Integer, c As Integer
oTable = oDoc.Tables(1)
oTable.Range.ParagraphFormat.SpaceAfter = 6
For r = 1 To 1
For c = 1 To 4
oTable.Cell(r, c).Range.Text = "r" & r & "c" & c
Next
Next

'update table in header
Dim footerRange As Word.Range = oDoc.Sections(1).Headers(Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage).Range.Tables(1)
footerRange.Cells(1).Range.Text = "RR"

Error:
"The requested member of the collection does not exist."
in:

Dim footerRange As Word.Range = oDoc.Sections(1).Headers(Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage).Range‌​.Tables(1)

This didn't work, got a error message "The requested member of the collection does not exist." at line
headerRange.Tables(1).Cell(1, 1).Range.Text = "RR"

Open in new window

Are you trying to edit the footer or the header

Dim footerRange As Word.Range = oDoc.Sections(1).Footers(Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage).Range
 footerRange.Tables(1).Cell(1, 1).Range.Text = "RR"

Could you send a dummy word file?
