XCLN: Attaching Digitally Signed Messages to an Eform

• Microsoft Exchange Windows 95 client, version 4.0
• Microsoft Exchange Windows 3.x client, version 4.0
• Microsoft Exchange Windows NT client, version 4.0

SUMMARY

You may want to digitally sign an Eform for groupware and tracking purposes. You cannot digitally sign an Eform using Visual Basic 4.0, but you can have a RichEntry field on the Eform to which you can attach an already digitally signed or encrypted message.

MORE INFORMATION

1. Make sure that you have enhanced security installed and running on your Exchange Server.

2. Have the user that wants to send a secure Eform create a message and digitally sign or encrypt the message and send it to their mailbox.

3. From the client Inbox folder select the encrypted message that was just received. On the File menu, select Save As and select Save File As Type. Select message format. This will save the message as an .MSG file.

4. Start the EForms designer and create your form. Make sure that there is a RichEntry field on the form. The RichEntry field should also have a reference name of MAPI_BODY_CUSTOM; this will allow you to add file attachments to this field.

5. Generate and install the form into the forms registry.

6. Launch the form from the client. Click the RichEntry field to highlight it.

7. Select Insert/File and select the .msg file that you saved earlier. The message should show up in the RichEntry field as an envelope icon.

The steps above allow for the full functionality of an encrypted or digitally signed message, as long as the enhanced security is installed.
