SUMMARY
=======

NotesDem.exe is an MFC sample for Windows CE that demonstrates how to read and
write the NOTES field of the Contacts Database using the RichInk control. The
NOTES field in the Contacts application is not the same field as HHPR_NOTES used
in the address card structure. Actually, it is not even part of the addresscard
structure so you must use the Windows CE Database APIs to get access to it.

Microsoft used the most current virus detection software available on the date of
posting to scan this file for viruses. After it is posted, the file is housed on
secure servers that prevent any unauthorized changes to the file.

The property ID of the NOTES field is 0x170041. It contains binary data in the
RichInk control format. There is an article "\Windows CE Platform
SDK\Support\RichInk\RichInk.doc" that describes how to use the RichInk control.

Reading the NOTES field is not very difficult. The following code taken from
NotesDemo.exe shows how you could read the field into a RichInk control:

     HANDLE h_contact;
     CEPROPVAL* propval;
     WORD  propsrecv = 1;
     CEPROPID ceprops[] = {0x170041};
     DWORD buflen = 0;
     PEGOID id = GetAddressCardOid(m_CardIndex);
     DWORD index;

     h_contact=CeOpenDatabase(&contactsid,_T("Contacts Database"),0,0,NULL);
     CeSeekDatabase(h_contact,CEDB_SEEK_CEOID,id,&index);

     if(!CeReadRecordProps(h_contact,CEDB_ALLOWREALLOC,&propsrecv,
                           ceprops,(unsigne d char**)&propval,&buflen))
     {
        MessageBox(_T(" Failed to read data! "));
     }

     ::SendMessage(m_hRichInkCtrl,IM_CLEARALL,0,0);
     ::SendMessage(m_hRichInkCtrl,IM_SETDATA,
                   (WPARAM)propval->val.blob.dwCount,
                   (LPARAM)propval->val.blob.lpb);
     CloseHandle(h_contact);

The NotesDem.exe sample also demonstrates how to write to the NOTES field.

NOTE: RichInk.h includes the calerror.h file. This file was not distributed with
the Windows CE Toolkit for Visual C++ 5.0. This include can be commented out for
the build. This control does not exist for the x86 emulation mode.
