How To Cause EFD Forms to Display Named Props Set from Ext. MAPI (178319)

MORE INFORMATION

The following code works for one named property. You can modify it for more then one property. This code calls separate functions to set the standard properties on the message and to set the recipients of the message. You may substitute your own functions for these.

The key to making this work is the MS_EXCHANGE_01 property. If you look at the VB source to your Form you will find that it checks for this property to be set on the message. If this property is not set, your other properties will not be read into their fields.

This code does not free all its memory or release its objects. You should of course add this as would be appropriate to your application:

    HRESULT SendMapiMessage()
    {
       HRESULT            hr;
       LPMESSAGE          lpMsg = NULL;
       MAPINAMEID         NamedID;
       LPMAPINAMEID       lpNmid = &NamedID;
       LPMAPIFORMINFO     lpFormInfo = NULL;
       LPMAPIFORMMGR      lpMgr = NULL;
       SPropValue         pProp;
       LPSPropTagArray    lpNamedPropTags = NULL;
       SMAPIFormPropArray *lpFrmPropAry =NULL;

       // Create a new message
       hr=lpFolder->CreateMessage(NULL,MAPI_DEFERRED_ERRORS,&lpMsg);
       if(FAILED(hr)) goto oops;

       // Open Forms Manager
       hr=MAPIOpenFormMgr(poSession,&lpMgr);
       if(FAILED(hr)) goto oops;

       // Get the Forms Info object
       hr=lpMgr->ResolveMessageClass("IPM.NOTE.MyNote",
                      MAPIFORM_EXACTMATCH,lpFolder,&lpFormInfo);
       if(FAILED(hr)) goto oops;

       // Get all the published properties of the form
       hr = lpFormInfo->CalcFormPropSet(0,&lpFrmPropAry );
       if (FAILED(hr)) goto oops;

       // Set First Property for demonstration purposes
       // You could set all the properties here if you wished
       // by using each element in the aFormProp array
       NamedID = lpFrmPropAry ->aFormProp[0].nmid;

       // Get Tags for these properties
       hr = lpMsg->GetIDsFromNames(1, &lpNmid, MAPI_CREATE,

       pProp.Value.lpszA = "Your string here";

       // Set the property
       hr = HrSetOneProp(lpMsg, &pProp);

       // Set EFD property to allow EFD to read and set fields.
       // You should check your VB code to ensure that this is
       // the correct name of the field in your project

       NamedID.ulKind = MNID_STRING;

       pProp.dwAlignPad = 0L;
       pProp.Value.b    = 1;

       // And once again set the property
       // Normally you would want to use one call to SetProps
       // with an array of properties to set
       hr = HrSetOneProp(lpMsg, &pProp);

       // Set Message Class - this could be set with other props
       // Setting here for illustration purposes
       pProp.ulPropTag = PR_MESSAGE_CLASS;
       pProp.dwAlignPad = 0L;
       pProp.Value.lpszA = "IPM.NOTE.MyNote";

       hr = HrSetOneProp(lpMsg, &pProp);
       if (hr) goto oops;

       // Here you would set all other outgoing Message props
       hr = SetOutgoingProps(lpMsg);
       if (hr) goto oops;

       // Here you would set the recipients of your message
       hr = SetRecips(lpMsg);

       // Finally, sumbit the message
       hr = lpMsg->SubmitMessage(0);
