PC Forms: MEFPKG.DAT File Size Limited to 64K (135351)


The information in this article applies to:

  • Microsoft Electronic Forms Designer
This article was previously published under Q135351

SUMMARY

The Microsoft Electronic Forms Designer uses a special attachment (MEFPKG.DAT) that is enclosed with a mail message. The attachment contains data and information for the read form. The Electronic Forms Designer does not support forms that have MEFPKG.DAT files larger than 64K.

MORE INFORMATION

If you attempt to call the electronic form's MEFWriteItem function with an attachment larger than 64K, you may get the following error:
MEF_DISK_FULL
The reason for the 64K limit is not due to a size limitation on the electronic forms attachment itself. The electronic forms MEFWriteItem function calls the Microsoft Windows Application Program Interface (API) function, WritePrivateProfileString, that has this limitation.

Additional information about the Windows API and WritePrivateProfileString can be found in the Microsoft Windows Software Development Kit (SDK) "Programmer's Reference."
