|Access Developer Reference|
expression A variable that represents a Form object.
You can set this property to No to allow users to view and edit existing records but not to delete them. When AllowDeletions is set to Yes, records may be deleted so long as existing referential integrity rules aren't broken.
If you want to prevent changes to existing records (make a form read-only), set the AllowAdditions , AllowDeletions, and AllowEdits properties to No. You can also make records read-only by setting the RecordsetType property to Snapshot.
When the AllowDeletions property is set to No, the Delete Record command on the Edit menu isn't available.
|When the Data Mode argument of the OpenForm action is set, Microsoft Access will override a number of form property settings. If the Data Mode argument of the OpenForm action is set to Edit, Microsoft Access will open the form with the following property settings:|
- AllowEdits — Yes
- AllowDeletions — Yes
- AllowAdditions — Yes
- DataEntry — No
To prevent the OpenForm action from overriding any of these existing property settings, omit the Data Mode argument setting so that Microsoft Access will use the property settings defined by the form.
The following example examines the ControlType property for all controls on a form. For each label and text box control, the procedure toggles the SpecialEffect property for those controls. When the label controls' SpecialEffect property is set to Shadowed and the text box controls' SpecialEffect property is set to Normal and the AllowAdditions, AllowDeletions, and AllowEdits properties are all set to True, the
intCanEdit variable is toggled to allow editing of the underlying data.
