get line range with C++ (word 2010)

[BCN 163]

I want to get the range of a line cursor in. VBA code (word2010) looks like this: ================================================ ActiveDocument.Bookmarks.Item("\LINE").Range C++ code looks like this: ================================================ CBookmarks oBookMarks = oDoc.get_Bookmarks(); VARIANT varName; varName.vt = VT_BYREF|VT_I1; char buff[6] = {"\\LINE"}; varName.pcVal = buff; CBookmark0 oBookMark = oBookMarks.Item(&varName); VBA code works perfectly but C++ code triggers some exception(required members does not exist). Anyone knows why? I really appriciate for your help.

You are passing a string using the VARIANT pcVal member. Strings are usually passed using the bstrVal member with type VT_BSTR. When using MFC, you may use the COleVariant type which creates a VT_BSTR when passing a string:

CBookmark0 oBookMark = oBookMarks.Item(COleVariant(_T("\\LINE")));

Another error may be the name of the used function oBookmarks.Item(). Please check if this functions exists. If you have imported a typelib, see the generated header file. With C++ OLE automation, many item access function are named GetItem() and SetItem().

thanks very much. the problem is solved. The reason is that I used the wrong VARIANT type.(I am puzzled on using VARIANT)
