This article describes the updates to Messaging Application Program Interface (MAPI) for Microsoft Visual Basic versions 2.0 and 3.0 for Windows that were made for version 1.0 of Microsoft Electronic Forms Designer. For an explanation of the MAPI changes, please refer to the Electronic Forms Designer "Developer's Guide," Chapter 11, "Simple MAPI for Visual Basic."

NOTE: The MAPI information from Electronic Forms Designer supersedes the MAPI information in the version 3.2 Microsoft Mail for PC Networks "Technical Reference" manual.

  • Incorporated the following information throughout Chapter 11 of the "Developer's Guide":

    The following two return values are documented in the "Technical Reference" manual, but are not used and should be ignored:


    The following three return values are incorrectly documented in the "Technical Reference" manual:

          Technical Reference Uses    Header Files Use

    Your applications should use the return value names listed in the header files.

    This information is in the "Technical Reference" README file and should be added to the "Technical Reference" manual.
  • Deleted the Originator field from the MapiMessage type (pages 198-199).

    This field is documented in the "Technical Reference" manual but it does not exist; if you use this field, your code will not compile.

  • Added additional information about the Subject field of MapiMessage (page 199).

    Add the following information to the "Technical Reference" manual:

    (Messages saved with MAPISaveMail are not limited to 256 characters.)

  • Changed the description of the RecipClass field of MapiRecip (page 200).

    Change the following description in the "Technical Reference" manual

    (Messages can be sorted by recipient class.)


    (Recipients can be sorted by recipient class.)

  • Changed the description of the EditFields parameter of MAPIAddress (page 202).

    Changed the Recips parameter to the Recipients() parameter throughout the description. Correct the "Technical Reference" manual to correctly reference this parameter.
  • Added a "Flags" parameter to MAPISaveMail (pages 219-220).

    Add this parameter to the MAPISaveMail function in the "Technical Reference" manual.
