MS Word delete page break

How can I delete a particular break in the document? There is an example of accessing breaks collection through a window pane, but what if my application is running windowless? (What I don't like in vba reference is the ambiguity of objects accessors. Is a window pane the only class able to access breaks collection?)

//MS Word VBA referense
    Dim objBreaks As Breaks 

Set objBreaks = ActiveDocument.ActiveWindow _ 
 .Panes(1).Pages(1).Breaks

Also, not to create additional question: I'm getting error Type mismatch when trying to InsertBreak via Range using parameters (for instance, wdPageBreak or wdLineBreak). But it's ok, to InsertBreak parameterless. Am I the only one getting such a behaviour, or is it another Word API bug?

//MS Word VBA Reference
Set myRange = ActiveDocument.Paragraphs(2).Range 
With myRange 
 .Collapse Direction:=wdCollapseEnd 
 .InsertBreak Type:=wdPageBreak 
End With

//c++ code
HRESULT hr = pWordDoc->GetParagraphs()->Item(1)->GetRange()->
        InsertBreak(&variant_t(Word::wdPageBreak)); //hr = 0x80020005 TypeMismatch
hr = pWordDoc->GetParagraphs()->Item(1)->GetRange()->
            InsertBreak(&vtMissing); // hr = S_OK
