XmlForm.Signed Property (Microsoft.Office.InfoPath)

Gets a value that indicates whether a form has been digitally signed using digital signatures.

Namespace: Microsoft.Office.InfoPath
Assembly: Microsoft.Office.InfoPath (in microsoft.office.infopath.dll)

Syntax

'Declaration
Public MustOverride ReadOnly Property Signed As Boolean
'Usage
Dim instance As XmlForm
Dim value As Boolean

value = instance.Signed

public abstract bool Signed { get; }

Property Value

true if the entire form or one or more sections of signable data have been digitally signed; otherwise false.

Remarks

The Signed property is true, if the entire form or one or more sections have been digitally signed. If false, the form has not been digitally signed, or a user has removed all signatures from the form.

InfoPath uses XML Signatures to digitally sign forms.

Note

If a form has been digitally signed, its underlying XML document is placed in a read-only state.

This member can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.

This type or member can be accessed from code running in forms opened in Microsoft Office InfoPath 2007 or in a Web browser.
