Invoking SaveAs dialog manually crashes Word

[Levente]

Hello,

I have a simple Word add-in. In the OnBeforeSave event, I need top show the
SaveAs dialog manually. If I do this AND also set the parameter pbSaveAsUI
passed to OnBeforeSave to VARIANT_TRUE (indicating that I already displayed
the SaveAs dialog and I do not want it shown again), then Word will crash
with an access violation AFTER exiting my event handler.

What I do is lilke this:

_ATL_FUNC_INFO OnDocBeforeSaveEventInfo = { CC_STDCALL, VT_EMPTY, 3,
{VT_DISPATCH, VT_BOOL | VT_BYREF, VT_BOOL | VT_BYREF} };

STDMETHODIMP CWordSink::OnDocBeforeSave(IDispatch *pDocument, VARIANT_BOOL
*pbSaveAsUI, VARIANT_BOOL *pbCancel)
{
CComQIPtr<Word::_Document> ptrDoc = pDocument;

DialogsPtr ptrDialogs = m_ptrApplication->Dialogs;
DialogPtr ptrSaveAsDlg = ptrDialogs ?
ptrDialogs->Item(wdDialogFileSaveAs) : NULL;
ptrDialogs = (IUnknown*)NULL;

if(ptrSaveAsDlg)
ptrSaveAsDlg->Show();

*pbSaveAsUI = VARIANT_FALSE;

return S_OK;
}

It only happens in WordXP and Word2003, not in Word2000. I also observed
that if I close the SaveAs dialog with Cancel, then it will not crash.

If anyone can give me some help/hints it would be greately appreciated.
Thanks a lot!

Best regards,
Levente

Hi Levente,

If I'm understanding correctly how you've interpreted the DocumentBeforeSave
event, then I think you need to go back and read the Help again. Setting
SaveAsUI to true should be showing the dialogbox:

SaveAsUI True to display the Save As dialog box.

I believe you want to set it to False?
