PC Forms: Incorrect Data Displayed in Subform

• Microsoft Electronic Forms Designer, version 1.0, running with Microsoft Mail for PC Networks, version 3.0 or 3.2

SUMMARY

While reading a message created with a version 1.0 Microsoft Electronic Forms Designer custom form, you may notice that incorrect information is displayed in a subform. This problem can occur if E-Form caching is turned on and the Hide method in Microsoft Visual Basic was used to dismiss the window. To properly use subforms with caching turned on, the Visual Basic Unload method should be used to dismiss the forms.

MORE INFORMATION

With the Microsoft Electronic Forms Designer, you can create a custom form to include subforms that are displayed in addition to the form's main window. You can use two methods to dismiss a subform in Visual Basic: Hide and Unload. The Hide method simply removes the dialog box from view; Unload removes the dialog box from memory.

When E-Form caching is turned on, it is important that you use the Unload method to dismiss subforms. Otherwise, if you use the Hide method, when a message of the same message class is read, the first instance of the subform will always be displayed because it is cached in memory. The Unload command removes the subform from memory and therefore allows each message to perform as expected.

For more information on subforms, see pages 95-102 of the Microsoft Electronic Forms Designer "Developer's Guide."
