Impossible to Open a PDF on a bookmark with the WebBrowser control

Hello,

Does someone know if when using the Excel VBA WebBrowser control in a UserForm, it is possible to open a PDF file at a given bookmark ?

No problem to make a basic open but it seems difficult to deal with Bookmarks.

I have created the bookmarks in Word, and when saving the doc as a pdf file, I use the "Options" and ask for handling the Word bookmarks.
By the way, when I open the pdf in Acrobat (or in Chrome or MSIE), I see the bookmarks I have created and they work.

But again, when I try to open the file in the WebBrowser control ( MyWebBrowser.Navigate "file:///C:\MyPath\FilePDF.pdf#TheBookmark"), it just opens the file and ignores the bookmark.
Thanks
