XPS Sample Driver question

Question

Hi,

I am trying to modify xpsdrvsmpl to call another program shortly after the document

starts to "print". Where would be the best place to place the CreateProcess or ShellExecute

call so that it only executes once? Thanks

Randy

Answer 1

Hi!

You can to this in the User Interface DLL. see http://msdn.microsoft.com/en-us/library/bb734121.aspx with the DOCUMENTEVENT_STARTDOC event.

Answer 2

This worked well until I tried to move my driver to 64-bit vista and windows 7. It appears that the STARTDOC and ENDDOC events
are not being called. Is this true and if so what can I do to workaround? Thanks

Answer 3

I got it to work after adding the following to DOCUMENTEVENT_QUERYFILTER:

if (pvOut)
            {
                DOCEVENT_FILTER* pFilter = (DOCEVENT_FILTER*)pvOut;
                pFilter->cElementsReturned = 6;
                pFilter->aDocEventCall[0] = DOCUMENTEVENT_ENDDOCPOST;
                pFilter->aDocEventCall[1] = DOCUMENTEVENT_STARTDOC;
                pFilter->aDocEventCall[2] = DOCUMENTEVENT_ENDDOC;
                pFilter->aDocEventCall[3] = DOCUMENTEVENT_STARTPAGE;
                pFilter->aDocEventCall[4] = DOCUMENTEVENT_ENDPAGE;
                pFilter->aDocEventCall[5] = DOCUMENTEVENT_XPS_ADDFIXEDDOCUMENTSEQUENCEPOST;
                *piResult = DOCUMENTEVENT_SUCCESS;
                ret = DOCUMENTEVENT_SUCCESS;
               
            }
            else
            {
                *piResult = DOCUMENTEVENT_UNSUPPORTED;
                ret = E_NOTIMPL;
            }

I also made sure that piResult was not set as an unreferenced parameter

Once these were added, the STARTDOC, ENDDOC, etc.. events were fired in windows x64.
